+ The prevalence of pregnancy complications are on the rise globally
14
+ with severe consequences. According to the World Health Organi-
15
+ zation (WHO, 2009), every minute, at least one woman dies and
16
+ 20 are affected by the complications related to pregnancy or child-
17
+ birth. While the root cause of pregnancy complications is unclear, it
18
+ likely has physical, psychological, social, and spiritual aspects. The
19
+ Vedas are a rich source of antenatal health care guidelines in all
20
+ these aspects. The primary objective of the authors was to compile
21
+ the scriptural and scientific evidence for a holistic antenatal model
22
+ of yoga with emphasis on sociocultural Indian practices.
23
+ Millions of women globally suffer from some form of pregnancy complica-
24
+ tion each year (World Health Organization [WHO], 2009). While scientific
25
+ advances in antenatal health care have saved many lives with reduced ma-
26
+ ternal and infant mortality (Seibel, Kiessling, Bernstein, Bernstein, & Seibel,
27
+ 1993), they have not been able to explain the root cause of pregnancy
28
+ complications and, as a result, the prevalence of these disorders is on the
29
+ rise (Narendran, Nagarathna, & Nagendra, 2008). Maternal stress has been
30
+ implicated as a contributing factor to the etiology of many complications
31
+ of pregnancy (Zamorski & Green, 1996). Yoga has been shown to reduce
32
+ maternal stress and improve pregnancy outcomes (Rakhshani et al., 2012).

+ Holistic Antenatal Model
39
+ 257
40
+ Based on previous studies, the authors believe that a holistic model based
41
+ on the yogic and Ayurvedic guidelines can be effective in the management
42
+ of low-risk and high-risk pregnancies.
43
+ A pregnancy complication is defined as a problem that arises during
44
+ pregnancy and can potentially put the health of the mother, fetus, or both
45
+ at risk (Beers, Fletcher, Jones, & Porter, 2003). According to the WHO, more
46
+ than 20 million pregnant women worldwide annually suffer from at least
47
+ one obstetric complication of pregnancy (WHO, 2009), excluding Caesarean
48
+ section; with miscarriage, preterm deliveries, low birth weight, and fetal de-
49
+ formities being the most prevalent (Porter, 2009). While the root causes of
50
+ these disorders are not clear, maternal stress has been shown to play a
51
+ major role in their development (Roy-Matton, Moutquin, Brown, Carrier, &
52
+ Bell, 2011). Maternal stress has been shown to adversely affect pregnancy
53
+ outcomes (Zamorski & Green, 1996). In fact, several studies have reported
54
+ that events in the maternal environment will filter through the placental
55
+ barrier and can affect the development of the placenta (Grammatopoulos,
56
+ 2008; Hecht et al., 2008). Furthermore, there is now mounting evidence that
57
+ maternal stress can not only increase the risk of morbidity and premature
58
+ mortality (Pinar & Carpenter, 2010) but it can also predispose the affected
59
+ individuals to diseases over the course of their lives (Li & Wi, 1999). In
60
+ addition to maternal psychological stress, poor diet and sedentary lifestyle
61
+ of the mother has been linked to increased risk of complications during
62
+ pregnancy (Krishna & Harigopal, 1979; Saraswati, 2008). Additionally, ma-
63
+ ternal diet has been shown to influence fetal growth (Drake et al., 2012).
64
+ Therefore, maintaining a good regime of diet, exercise, and a lifestyle that
65
+ promotes minimum psychological stress for the mother can be a prelude to
66
+ a successful pregnancy.
67
+ Yoga, a 5,000-year-old Indian practice, is a holistic approach that pro-
68
+ motes physical, mental, and spiritual well-being in practitioners (Bijlani,
69
+ 2008). A recent review has enlisted the potential positive effects of yoga
70
+ during pregnancy (Babbar, Parks-Savage, & Chauhan, 2012). Yoga has been
71
+ shown to reduce perceived pain (Reis, 2012), improve sleep efficiency (Bed-
72
+ doe, Lee, Weiss, Kennedy, & Yang, 2010), promote shorter duration of
73
+ labor (Chuntharapat, Petpichetchian, & Hatthakit, 2008), and improve ma-
74
+ ternal quality of life (Rakhshani, Maharana, Raghuram, Nagendra, & Venka-
75
+ tram, 2010). The Integrative Approach of Yoga Therapy (IAYT) is a set of
76
+ yoga modules to address many lifestyle-related health conditions. In low-
77
+ risk pregnancy, IAYT has been shown to improve pregnancy outcomes
78
+ (birthweight and APGAR scores) and reduce the frequency of occurrence of
79
+ pregnancy complications, including pregnancy-induced hypertension (PIH),
80
+ intra-uterine growth restriction (IUGR), and small for gestational age (SGA;
81
+ Narendran, Nagarathna, Narendran, Gunasheela, & Nagendra, 2005b). In
82
+ high-risk pregnancy, yoga has been shown to dramatically reduce incidence
83
+ of hypertension-related complications, improve pregnancy outcomes, and
84
+ 258
85
+ A. Rakhshani et al.
86
+ promote the health of the fetus (Rakhshani et al., 2012). An important
87
+ observation in the latter study was that participants were inclined to go
88
+ to their hometowns at the first sign of any complication, and more so at the
89
+ time of delivery. Further inquiry revealed that these tendencies were woven
90
+ into the fabric of the Indian culture and perhaps into many other cultures
91
+ around the globe. The importance of local traditions to modern clinical trials
92
+ is another reason for the development of this model.
93
+ Sociocultural factors play an important role in increasing maternal stress
94
+ during pregnancy. Through millenniums, Indian traditions have evolved to
95
+ reduce such stress and promote well-being in the mother and her fetus
96
+ (Pandey, 2002). The focus continues after the child is born and throughout
97
+ his or her life (Pandey, 2002). In fact, Indian beliefs are based on the ide-
98
+ ology that life is a precious gift from God and it should be celebrated, at
99
+ every stage, from conception to death (Tull, 2008). From this social point of
100
+ view, a baby is the product of that sacred union, and, therefore, it is con-
101
+ sidered a divine gift. It is not then surprising that there are numerous rituals
102
+ centered around marriage and pregnancy in the Indian traditions. These rit-
103
+ uals, often referred to as Samsk¯
104
+ aras (a word which literally means “making
105
+ complete”) in the Vedic literature, are meant to infuse divinity at every step
106
+ of the reproductive process (Tull, 2008). Such rituals are not exclusive to the
107
+ Indian traditions though. Nearly every culture around the globe has strong
108
+ established rituals for marriage, pregnancy, and birth (Hamon & Ingoldsby,
109
+ 2003).
110
+ The primary objective of the authors was to formulate a potential com-
111
+ prehensive and holistic antenatal health care model that can provide guide-
112
+ lines: (a) for design of future studies in this important area, and (b) for
113
+ providing sustainable and effective health care to pregnant women. The
114
+ model takes into account previous studies involving yoga and nutrition dur-
115
+ ing pregnancy, as well as the related Vedic scriptures and the Indian ritu-
116
+ als, Samsk¯
117
+ aras, that may be of value for timing the interventions. Although
118
+ the social and spiritual aspects of the model are geared toward the Indian
119
+ traditions and philosophies, practices from other traditions could easily be
120
+ incorporated into the model without affecting the other elements of it.
121
+ Health From the Modern Medicine Point of View
122
+ The WHO defines health as “a state of physical, mental, social and spiritual
123
+ well-being, and not merely the absence of disease or infirmity” (Larson, 2006,
124
+ p. 181). We chose this definition as the framework to develop this holistic
125
+ antenatal model.
126
+ Health From the Vedic Point of View
127
+ From the Vedic point of view, the physical body is the grossest part of
128
+ the human existence. There are also other metaphorical bodies, sometimes

135
+ called ko´
136
+ sa (
137
+ ) or sheaths, that are more subtle than the physical body
138
+ but play equally important roles in our emotional, mental, and spiritual well-
139
+ being (Rakhshani, 2013). Including the physical body, there are a total of
140
+ five ko´
141
+ sas that are collectively referred to as pancha ko´
142
+ sas (
143
+ ). Yoga
144
+ seeks the root causes of illnesses within the four subtle bodies, believing
145
+ that the diseases of the physical body are manifestations of disturbances in
146
+ those metaphorical layers (Rakhshani, 2013). Table 1 outlines the different
147
+ bodies and their primary functions.
148
+ Manomaya ko´
149
+ sa is of particular importance in maintaining optimum
150
+ health. Disturbances in this ko´
151
+ sa, due to lifestyle stress or past traumas,
152
+ interfere with the flow of prana in pranamaya ko´
153
+ sa, which ultimately result in
154
+ failure of a particular weak organ in the annamaya ko´
155
+ sa. Such disturbances
156
+ can also affect the vijnanamaya ko´
157
+ sa and distort viveka (discrimination),
158
+ which in turn blocks proper contacts with the anandamaya ko´
159
+ sa (blissful
160
+ state). Figure 1 shows this interaction graphically.
161
+ Embryology From the Vedic and Modern Standpoints
162
+ The classic Ayurvedic literature describes the fertilization process, under the
163
+ heading of “S¯
164
+ ar¯
165
+ ira Sth¯
166
+ ana.” These texts also give details on the composition of
167
+ the matter based on the following five elements that constitute the universe
168
+ outside and inside of the body: (a) earth (prthvi = solid), (b) fire (agni =
169
+ heat), (c) water (ap = fluid), (d) air (vayu = movement), and (e) space
170
+ (aakasa). The Vedic literature gives a particular emphasis on the role of vayu
171

+ Description
181
+ Annamaya ko´
182

183
+ “Anna” means food. This physical body needs food as its
184
+ nourishment “annadhyeva khalvimani bhut¯
185
+ ani jayante”
186
+ (everything is born out of physical matter); “annena jat¯
187

189
+ abhisa ˙
190
+ mvisanti” (they merge into anna); and “j¯
191
+ atanyannena
192
+ vardhante” (they grow because of anna).3 If this ko´
193
+ sa is
194
+ neglected, improvement in other ko´
195

196
+ impossible.
197
+ Pranamaya ko´
198
+ sa
199
+ “Pr¯
200
+ ana” means vital energy. It refers to the energy that is
201
+ responsible for the physiological activities of all living cells. Five
202
+ sections of the main pr¨
203
+
204
+ ea manage the functions in five zones:
205
+ pr¯
206
+ ana (respiration and special senses), ap¯
207
+ ana (defecation,
208
+ micturition, menstruation, etc), sam¯
209
+ an¯
210
+ a (digestion), vy¯
211
+ an¯
212
+ a (touch
213
+ sense, circulation of fluids all over etc), and ud¯
214
+ ana (thinking,
215
+ belching, vomiting, etc).4 pr¯
216
+ ana circulates through an intricate
217
+ and invisible system of pathways called nadis. The main three
218
+ nadis are ida, pi`
219
+ ıgal¯
220
+ a, and c
221
+ ¸uc
222
+ ¸uman¨
223
+ a in the spine. They branch
224
+ out to about 72,000 nadis throughout the body. The ida and
225
+ pi ˙
226
+ ngal¨
227
+ a channels correlate with the left and right nostrils, making
228
+ it possible to manipulate pr¯
229
+ ana through controlled breathing.
230
+ Manomaya ko´
231
+ sa
232
+ “Manah” means mind. This ko´
233
+ sa is the seat of perception and
234
+ emotions. Using the five senses, information is acquired to create
235
+ a perception of the world outside and then used to prepare
236
+ appropriate emotional responses to those perceptions.
237
+ Vijnanamaya ko´
238
+ sa
239
+ “Vji˜
240
+
241
+ ana” means knowledge. This is the seat of wisdom that
242
+ facilitates the thinking process of the mind. Utilizing this faculty,
243
+ we are able to discriminate right from wrong and make
244
+ appropriate judgments (viveka) for a healthy lifestyle. More
245
+ significantly, this is the place of intuition that is used when
246
+ analytical process fails to guide us.
247
+ Anandamaya ko´
248
+ sa
249
+ “¯
250
+ ananda” means bliss. This forms the unchanging template of
251
+ (existence, consciousness, and bliss) of our being on which the
252
+ other ko´
253
+ sas carry on their activities. This is also the basic stuff of
254
+ this entire creation. ¨
255
+ anandamaya ko´
256
+ sa is experienced as a
257
+ blissful ecstatic state of pure awareness when all mental activity
258
+ ceases. The main approach of yoga therapy as a mind-body
259
+ medicine is to maintain the practitioner in this state that is
260
+ regarded as a state of perfect health.
261
+ 1The bodies are listed from the grossest, the physical body, to the subtlest, the bliss body.
262
+ 2‘Maya’ means illusion. Therefore, all these five bodies must be conquered by the spiritual practitioner of
263
+ yoga in order for he or she to realize the nature of his soul, which sits beyond these illusions.

268
+ conception, therefore, Saumanasya (happiness/tranquility of mind) of the
269
+ mother is considered to be the most important factor (Sharma & Bhagwan,
270
+ 1992). The unborn child is also said to emulate the nature of the maternal
271
+ mindset during fertilization (Sharma & Bhagwan, 1992).
272
+ Holistic Antenatal Model
273
+ 261
274
+ The Garbha or embryo is described in the Vedic literature as the union of
275
+ the sperm, the ovum, and the soul in the womb. First, the conscious element
276
+ (i.e., the soul) endowed with mental faculty, unites with the mahabhutas
277
+ (maha means great and bhutas means elements; the term refers to the five
278
+ great elements: ether, air, fire, water, and earth) in a fraction of a second.
279
+ This would be a Vedic explanation for the reason why in-vitro fertilization
280
+ fails so often. The embryo also requires the maternal and paternal factors:
281
+ saatmya (wholesomeness), rasa (digestive product of mother’s food), and
282
+ mind (Bhishagratna, 1991). The mind is said to propel the jeeva (soul) into
283
+ the uterus impelled by the deeds of previous lives.
284
+ The Bh¯
285
+ agavata Pur¯
286
+ ana states the concept of conception in canto 3, chap-
287
+ ter 31, verse 1, as, “The living entity, the soul, is made to enter into the womb
288
+ of a woman through the particle of male semen to assume a particular type
289
+ of body (
290
+ )”
291
+ (Gupta & Valpey, 2013). This concept parallels science’s view that the sper-
292
+ matozoon joins the oocyte in the uterine tube to form a zygote. In the
293
+ following verse, the next development of the embryo is explained:
294
+ The sperm and the ovum mix on the first night and by the fifth night,
295
+ the union looks more like a bubble, which gradually turns into a lump
296
+ like a plum by the tenth night and later into an egg. (
297
+ )
298
+ Once again, an unprecedented description of mitosis is put forward. The
299
+ zygote becomes a morula (of 12 to 16 cells) after 5 nights and then develops
300
+ into a blastocyst with a fluid-filled center (just like a bubble) in 10 days (The
301
+ Endowment for Human Development, 2010). The accuracy of this develop-
302
+ ment is uncanny and clearly shows the ability of the seers to visualize the
303
+ process through meditation since there were no other means to do so at that
304
+ time. The next verse further explains the organ development of the embryo
305
+ in the first trimester:
306
+ By the end of the first month, the head is formed and by the end of
307
+ the first three months, the hands and the feet are formed along with
308
+ the nails, fingers, toes, body hair, and the bones. By this time, the
309
+ skin appears, as do the organ of generation and the other apertures
310
+ in the body, namely the eyes, nostrils, ears, mouth and anus. (
311
+ )
312
+ Once again, this passage mirrors discoveries of modern science with amazing
313
+ accuracy. Indeed, the formation of the brain starts at the very early stages
314
+ of embryo development. Between the fourth and fifth weeks of pregnancy,
315
+ the head has developed to a much larger size compared with the rest of
316
+ 262
317
+ A. Rakhshani et al.
318
+ the body, giving the embryo the look of a tadpole (The Endowment for
319
+ Human Development, 2010). In the same line, the next few verses describe
320
+ the growth of the organs formed in the first trimester.
321
+ The Sixteen Samsk¯
322
+ aras
323
+ It is important to point out that the role of women in Hindu society is
324
+ complex due to its dual nature. On one hand, they are viewed as fertile and
325
+ compassionate caregivers, but, on the other hand, they can be viewed as
326
+ hostile and overprotective (Wadley, 1977). A woman’s overemphasized role
327
+ as a caregiver may be the primary cause of her aggressiveness toward people
328
+ whom she suspects may want to hurt her family physically, financially, or
329
+ socially. A point of particular concern to her is an “evil eye” (or evil spirit)
330
+ that envies her life and wants to damage it through negative energy. Part
331
+ of the childbearing rituals are concerned with repelling such external forces
332
+ (Jacobson & Wadley, 1992) through mantras and divine offerings, which are
333
+ believed to ensure normal progression of the different stages of pregnancy
334
+ and provide the mother with the necessary social acceptance. Table 2 lists
335
+ the 16 most frequently practiced Samsk¯
336
+ aras in India. Here, we shall very
337
+ briefly describe only the first four, which are relevant from the point of
338
+ conception through delivery of the newborn.
339
+ First
340
+ Samsk¯
341
+ ara:
342
+ Garbh¯
343
+ adh¯
344
+ ana
345
+ (
346
+ )—The
347
+ conception
348
+ ritual.
349
+ “Garbha” means womb, and “adaana” means donation (Dasji, 2010). There-
350
+ fore, the term “Garbhadana” literally means donation to the womb (Alter,
351
+ 1997). In India, the procreation of offspring is regarded as necessary for
352
+ paying off debt to the forefathers (Dasji, 2010).
353
+ Second Samsk¯
354
+ ara: Pu ˙
355
+ msavana (
356
+ )—The ritual for seeking a male
357
+ offspring.
358
+ Pumsavana literally means engendering a male offspring. Tradi-
359
+ tionally, male offsprings have been preferred since they maintain the conti-
360
+ nuity of the family lineage (Pandey, 2003). Also, sons are required to perform
361
+ the necessary cremation rituals that guarantee a safe passage for the father
362
+ and the mother after they leave this world (Pandey, 2003). Some authors,
363
+ however, have distanced themselves from the gender connotation of this
364
+ Samsk¯
365
+ ara and have interpreted it as a ritual to secure a child full of vi-
366
+ tality (Tambe, 2011). After Garbhadhan Samsk¯
367
+ ara, and when symptoms of
368
+ pregnancy have manifested, the Pumsavana Samsk¯
369
+ ara is performed, usu-
370
+ ally during the second month of pregnancy when the moon is in a male
371
+ constellation. Pumsavana and Simantonyana (the third Samsk¯
372
+ ara) are only
373
+ performed during a woman’s first pregnancy (Dasji, 2010). During the cer-
374
+ emony, the pregnant woman consumes one bead of barley and two beads
375
+ of black grain, along with a little curd (Dasji, 2010). This is accompanied by
376
+ a Homa (a fire ritual, where offerings are given to the deities through fire)
377
+ and chanting of the following by the acharya (the priest; Dasji, 2010): “The
378

480
+ ara: S¯
481
+ imant¯
482
+ onnayana (
483
+ ) —A ritual for safe deliv-
484
+ ery.
485
+ The objective of this Samsk¯
486
+ ara is to ensure a complication-free preg-
487
+ nancy and a safe delivery of the child. It is usually performed in the fourth
488
+ month of pregnancy (Pandey, 2003). First, a prayer is offered to the deities
489
+ and, then, while combing the hair of his wife from front to back, the husband
490
+ chants the following to protect the fetus: “I perform this Simantonnayanam
491
+ Samsk¯
492
+ ara to please God and for the development of the fetus of my wife
493
+ and to remove any obstacles caused by evil spirits and to bring all things of
494
+ prosperity [to the fetus]” (Dasji, 2010, p. 17). Finally, “other old and young
495
+ ladies of the noble families bless the pregnant woman” (Dasji, 2010, p. 17).

498
+ Fourth Samsk¯
499
+ ara: J¯
500
+ atakarma (
501
+ ) —The ritual to purify the newborn.
502
+ Jatakarman literally means natal rites and it is similar in concept to that
503
+ of baptizing the newborn in Christianity. This Samsk¯
504
+ ara is performed right
505
+ before severing the umbilical cord. Its purpose is to ensure proper intellectual
506
+ development, adequate strength, and a long life for the newborn (Dasji,
507
+ 2010). The father places a mixture of honey and ghee on the tongue of the
508
+ child and blesses him with the following prayer: “You [the fetus] may become
509
+ strong like a stone. Brave against the enemies like the great sage Parshuram
510
+ and you may remain pious forever like the gold” (Dasji, 2010, p. 18). Then
511
+ the father cuts the umbilical cord and the child is bathed with milk to bless
512
+ him with physical, mental, and spiritual progress. Finally, the acharya chants
513
+ the following prayer to seal the ritual: “I perform this jatakarma Samsk¯
514
+ ara for
515
+ pleasing the God and to remove all kinds of obstacles produced by this child
516
+ staying in the womb and getting nourishments from the mother through the
517
+ placenta” (Dasji, 2010, p. 18).
518
+ The Integrative Approach of Yoga Therapy (IAYT)
519
+ Yoga is a holistic approach to well-being that originated in India (Bijlani,
520
+ 2008). It involves a combination of stretching, breathing, posture, and med-
521
+ itation that promotes health and spiritual growth in the practitioners (Chan-
522
+ dler, 2001). These techniques are lowimpact, noninvasive, and have few
523
+ side-effects (Benson & McCallie, 1979). A growing body of research data now
524
+ supports the use of yoga for prevention and management of chronic lifestyle-
525
+ related ailments (Bijlani, 2008; Hanser, 2009; McCall, 2007; Taylor, 2003). The
526
+ IAYT is a holistic approach of health management that uses kriyas, asanas,
527
+ pranayamas, meditation, devotional chanting, and self-analysis (Narendran
528
+ et al., 2008).
529
+ METHODS
530
+ An antenatal model was planned based on WHO’s definition of health and
531
+ the Vedic perspective of well-being with a focus on Indian sociocultural
532
+ practices (Samsk¯
533
+ aras). The model can easily be adapted to other cultures
534
+ and incorporate their traditions. We have adopted a systematic approach for
535
+ the development of the model, which consists of three phases that are ex-
536
+ plained below. Through this process, we research, collect, and put together
537
+ guidelines from the Vedic literature, the yogic sciences, and Ayurvedic
538
+ medicine to formulate a holistic model that addresses the well-being of
539
+ the women physically, psychologically, emotionally, socially, and spiritually.
540
+ Figure 2 illustrates the three developmental phases for this model.

+ medicine, was conducted and was summarized in the first section of this
549
+ article. In this phase, the results were compiled into a table based on their
550
+ potential applications to modern antenatal care.
551
+ Phase 2: Compilation of the data from the field.
552
+ The present model was
553
+ developed by incorporating the recommendations of health practices for the
554
+ well-being of pregnant women gathered in Phase I.
555
+ Phase 3: Development of the antenatal model.
556
+ The main aim of this
557
+ phase was to collect all available evidences for the effects of these health
558
+ practices. While there are some published data indicating the potential ben-
559
+ efits of yoga in pregnancy, we found that the literature lacks evidence on
560
+ the effects of another school of Indian medicine, particularly Ayurveda, that
561
+ is widely practiced in India. Hence, Ayurvedic physicians who have adopted
562
+ these Samsk¯
563
+ aras in their routine practices were interviewed and the relevant
564
+ collected data was compiled and has been presented below.

+ decoction of jujube fruit (known in India as badara and scientifically as Zizi-

701
+ followed by a medicated oil enema (anuv¯
702
+ asana basti), with oil prepared with
703
+ milk and madhura gana dravyas described above (Bhishagratna, 1991). The
704
+ pregnant woman is advised to consume rice cooked with milk and added
705
+ ghee for the additional protein needed for the proper development of the
706
+ fetus (Sharma & Bhagwan, 1992). Such a diet will provide proper nourish-
707
+ ment for the annamaya kosha, enriches the pranamaya kosha, and provides
708
+ calmness of the mind in the manomaya kosha (see Figure 1).
709
+ Several cleansing techniques, kriyas, that are safe and useful for healthy
710
+ progression of pregnancy and prevention of complications are incorporated
711
+ in the model. Vamana dhouti is recommended for prevention and treatment
712
+ of pregnancy-induced nausea and vomiting (Rao et al., 2009). Mild Kapal-
713
+ abhati (done at a rate of 27 breaths/minute) helps in normalizing breathing
714
+ patterns and promoting calmness of the mind during the first trimester of

716
+ A. Rakhshani et al.
717
+ low-risk pregnancies. Jalaneti is useful to cleanse the nasal passage and may
718
+ be safely practiced throughout high- and low-risk pregnancies.
719
+ Yogic postures aim to achieve mastery over the fluctuations of
720
+ the mind (
721
+ : y¯
722
+ oga´
723
+ scittavrtti nir¯

725

733

734

751
+ asana (lateral shavasana). Other asanas have been
752
+ shown to be safe in low-risk pregnancies (Rakhshani et al., 2010): tadasana
753
+ (mountain pose), ardhakati-chakrasana (lateral arc pose), trikonasana (tri-
754
+ angle pose), vajrasana (the ankle posture), vakrasana (spine twist pose),
755
+ siddhasana (sage pose), Baddhakonasana (bound ankle pose), upavista
756
+ konasana (sit with legs apart), malasana (garland pose), viparita karani (half
757
+ shoulder stand), and ardha-pavanamuktasana (folded leg lumbar stretch).
758
+ Breathing practices aim at reducing the breathing rate, which in
759
+ turn calm the mind (

793
+ aghr¯
794
+ asana ´
795
+ svasanam (tiger stretch breathing).
796
+ The asanas and the breathing exercises are intended to strengthen
797
+ the musculoskeletal system, stretch ligaments, massage organs, and bring
798
+ oxygen-rich circulation to the various parts of the body in the annamaya
799
+ kosha. In the pranamaya kosha, they move the prana, remove blockages in
800
+ the nadis, and open the chakras. Finally, and most importantly, they gradu-
801
+ ally make the mind one-pointed in the manomaya kosha (Rakhshani, 2013).
802
+ Daily care also plays an important role in the wellness of the expect-
803
+ ing mother. For example, after the thirty-sixthweek of gestation, Ayurvedic
804
+ physicians recommend the following: (a) daily bathing with water boiled
805
+ with leaves, such as those of castor bean (Eranda-Ricinus communis) and
806
+ five-leaved chaste tree (Nirgundi-Vitex negundo), which reduce the v¨
807
+ ata
808
+ dosha; (b) daily massage with medicated oils (Tripathi, 2009); (c) applica-
809
+ tion of enema (sth¯
810
+ apan¯
811
+ a basti) from twenty-eighth to thirty-second weeks
812
+ followed by unctuous enema (anuvasana basti) of medicated oil with milk
813
+ and decoction of drugs of sweet group, like madhuka (Shastri, 2009); and
814

815
+ 269
816
+ (d) insertion of vaginal tampons soaked with oil can be performed from
817
+ thirty-sixth week onward to lubricate the cervix, the vaginal canal, and the
818
+ perineum (Tripathi, 2009).
819
+ Psychological domain.
820
+ This forms the core of all practices recom-
821
+ mended at all levels because, from the Vedic point of view, stress be-
822
+ gins in the mind as suppressed emotions. The scriptures provide the log-
823
+ ical steps of arriving at an understanding of the nature of any emotion
824
+ (suppressed or expressed) and define it as “uncontrolled fast rewinding
825
+ of thoughts in the mind” (
826
+
827
+ amakr¯
828
+ odh¯
829
+ odbhavam v¯
830
+ egam;
831
+ Ranganathananda, 2000). All recommended practices are meant to reduce
832
+ stress by slowing down the mind (
833
+ : Manah pra´
834
+ saman¯
835
+ op¯
836
+ ayah).
837
+ These include meditation of various types. Many of the recommended prac-
838
+ tices have been used successfully as interventions in past studies (Rakhshani
839
+ et al., 2010; Satyapriya, Nagendra, Nagarathna, & Padmalatha, 2009). The
840
+ following pranayamas that have been used in several published studies have
841
+ been incorporated in the model: sectional breathing, nadishiddhi, Sheetali,
842
+ bharamari, Nadanusandhana (Satyapriya et al., 2009).
843
+ Social domain.
844
+ Trials targeting the Indian population should take into
845
+ account the Samsk¯
846
+ aras to reduce dropouts and attrition. Interventions be-
847
+ ginning prior to conception should include marital status as part of their
848
+ selection criteria and, in the event that unmarried couples are included,
849
+ the Garbhadana ceremony. Astrology is the cornerstone of the Indian cul-
850
+ ture. It would behoove the investigators, therefore, to consult with a reliable
851
+ astrologer to find the auspicious days during the duration of the study execu-
852
+ tion and incorporate them into the design. For example, if the interventions
853
+ are administered during the second month of pregnancy, knowing when the
854
+ moon is in its male constellation would allow women to anticipate the Pum-
855
+ savana Samsk¯
856
+ ara. Auspicious days during the fourth month of pregnancy
857
+ would also be the time that Simanatonayan Samsk¯
858
+ ara could be performed.
859
+ Studies targeting other populations of the world would need to incorporate
860
+ their own regional customs and rituals into the model.
861
+ Spiritual domain.
862
+ Responsibility (prabhutvam), tolerance (titiksha),
863
+ contentment (santosha), and self-confidence (aatma vishwasah) are some of
864
+ the essential qualities necessary for moving toward a healthy motherhood.
865
+ Yoga is defined as “freedom” or “personal autonomy”; to be able to shift
866
+ from established patterns of psychological responses to a desired response
867
+ at will. To do, not to do, or to do differently is the freedom we all pos-
868
+ sess (
869
+ kartumakartumanyath¯
870
+ a v¯
871
+ a kartum ´
872
+ sakyam;
873
+ Badarayana, 1960). This freedom evolves by dwelling in the inner silent
874
+ state marked by blissful awareness during yoga practices. There are numer-
875
+ ous such practices that could be incorporated in the design of trials based
876
+ on the teachings of the four paths of yoga, which are jnana yoga (yoga of
877
+ knowledge), bhakti yoga (yoga of devotion), karma yoga (yoga of service),
878
+ and raja yoga (yoga of controlling the mind): (a) dharana (concentration),
879
+ 270
880
+ A. Rakhshani et al.
881
+ (b) bhavana (contemplation on a deity), (c) pathana (study of the scriptures),
882
+ (d) satsanga (being in the company of wise people), (e) japaya (chanting of
883
+ the holy names), (f) seva (selfless service), (g) viveka (developing discrimi-
884
+ nation between right and wrong), (h) viragia (developing dispassion toward
885
+ the objects of the senses), and (i) bhakta (transforming hard emotions into
886
+ soft, divine emotions, as it is said in the Narada Bhakti sutra: the purest form
887
+ of love is devotion
888
+ parama pr¯
889
+ ema r¯
890
+ upa bhaktih). Practices of
891
+ bhakti yoga are deeply embedded in the Indian traditions starting with reg-
892
+ ular daily worship of the personal God (ishtadevata) to special celebrations
893
+ (Samsk¯
894
+ aras) with intense practices (vrat¯
895
+ as) for different phases of pregnancy.
896
+ The abode of the mother should be well fumigated, worshiped, and have
897
+ sound of the Vedic hymns (or other spiritual songs from other faiths) being
898
+ recited by br¯
899
+ ahman¯
900
+ as (holy priests). The pregnant woman after getting up in
901
+ the morning and performing her regular chores should be busy in worship
902
+ of god and should do selfless service (seva; Bhishagratna, 1991). By using
903
+ different religious icons from other faiths, these spiritual practices could be
904
+ utilized by other studies that use yoga and Ayurveda as interventions but are
905
+ targeting other world populations.
906
+ DISCUSSION
907
+ The authors’ aim was to compile the scriptural and scientific evidence for a
908
+ holistic antenatal model of yoga with emphasis on sociocultural Indian prac-
909
+ tices (Samsk¯
910
+ aras). We believe that the model provides practices that promote
911
+ positive well-being at physical, psychological, social, and spiritual levels as
912
+ recommended by the WHO in its definition of heath and by the yogic scrip-
913
+ tures. Except for the social elements, most of the other components of the
914
+ model are replicable in different cultures. While many other studies have
915
+ used various components of this model in trials conducted at different parts
916
+ of the globe, the mechanism of action of yoga in pregnancy is not clear.
917
+ Some speculations have been offered in the next section.
918
+ MECHANISMS
919
+ According to the studies we have reviewed, yoga-based therapies seem to be
920
+ promising interventions during pregnancy. None of these studies, however,
921
+ explain the underlying mechanisms of the physiologic and psychological
922
+ effects of yoga during pregnancy. The collective results suggest that the
923
+ reported improvements likely occur through a number of pathways.
924
+ Yoga by directly activating the vagus nerve may improve parasympa-
925
+ thetic output, leading to enhanced cardiac-vagal function, mood, energy
926
+ state, and related neuroendocrine, metabolic, and inflammatory responses
927
+ (Taylor, Goehler, Galper, Innes, & Bourguignon, 2010). Yoga may pro-
928
+ mote a feeling of well-being by reducing the activation and reactivity of the
929
+ Holistic Antenatal Model
930
+ 271
931
+ sympathoadrenal system through increased vagal activity (Bowman et al.,
932
+ 1997) and better autonomic reactivity after yoga as pregnancy advances
933
+ (Satyapriya et al., 2009). Improved stability of the hypothalamic pituitary
934
+ adrenal (HPA) axis may also contribute as evidenced by decreased corti-
935
+ sol levels in normal adults (Kamei et al., 2000; West, Otte, Geher, Johnson,
936
+ & Mohr, 2004) and increased early morning cortisol in pregnancy (Beddoe
937
+ et al., 2010; Kabat-Zinn, 1990) after yoga. Field attributes this to the “stimula-
938
+ tion of dermal and/or sub-dermal pressure receptors that are innervated by
939
+ vagal afferent fibers, which ultimately project to the limbic system including
940
+ hypothalamic structures involved in cortisol secretion” (Field, 2011, p. 6).
941
+ Another explanation could be that stress reduction, through mind manage-
942
+ ment, could have an impact on reduction of oxidative stress, which in turn
943
+ reduces pregnancy complications (Hsieh et al., 2012).
944
+ It is also possible that a yogic lifestyle has a positive impact on proper
945
+ placentation (particularly if practiced early in pregnancy), although research
946
+ data are needed to substantiate this. Improved blood volume and hemodilu-
947
+ tion with better blood supply to the placenta may be a major contribution of
948
+ the restful relaxation techniques used in yoga (Jayashree, Malini, Rakhshani,
949
+ Nagendra, & Nagarathna, 2013).
950
+ These speculations would not be complete without a reference to the
951
+ yogic vantage on the mechanism of action of yoga on the body given in the
952
+ yogic text by Patanjali (Woods, 2003) and others (Nagarathna & Nagendra,
953
+ 2001). These scriptures tell us that all of these practices produce calmness of
954
+ the mind in the manomaya kosha, which results in proper prana flow in the
955
+ pranamaya kosha and better functioning of the organs in the annamaya
956
+ kosha (Venkatesananda, 1984; Rakhshani, 2013):
957
+ (changing the lifestyle by good abiding to good coun-
958
+ seling, the samanya adhija vyadhi is destroyed (Gupta, 2013).
959
+ LIMITATIONS OF THE STUDY
960
+ The study is a retrospective presentation of the steps that were followed
961
+ over the years and not a prospective planned study to assess the valid-
962
+ ity and reliability of the model. Statistically acceptable checklists and scor-
963
+ ing were not used during the literature search. Not all authors of the arti-
964
+ cle met in groups before finalizing the model. No statistical calculations of
965
+ split half reliability or validity were planned because this was a preliminary
966
+ study.
967
+ STRENGTHS OF THE STUDY
968
+ The aim was to highlight the conceptual basis for the holistic practices
969
+ that were prevalent in ancient India that have been carried on (modified
970
+ 272
971
+ A. Rakhshani et al.
972
+ suitably) even today. This model formed the basis of the interventions used in
973
+ several control trials (Narendran, Nagarathna, & Nagendra, 2005a; Rakhshani
974
+ et al., 2010, 2012).
975
+ SUGGESTIONS FOR FUTURE WORK
976
+ Yoga is now widely recognized and practiced throughout the world. Ante-
977
+ natal yogic practices recommended in this model can be adapted and imple-
978
+ mented in different cultures. Future studies may cull out some of the mean-
979
+ ingful evidence-based cultural and spiritual practices from different cultures
980
+ that may be incorporated or reinstated for healthy progression of pregnancy
981
+ and promotion of well-being of the mother and the offspring.
982
+ CONCLUSION
983
+ Complications of pregnancy are serious life-threatening disorders with se-
984
+ vere economical and social consequences globally. Clearly there is a need
985
+ to identify a noninvasive and cost-effective solutions for the management of
986
+ these disorders. Several studies have shown yoga to be useful in management
987
+ of low-risk and high-risk pregnancies. The yoga and Ayurvedic guidelines
988
+ incorporated in this model are holistic treatments (both physical and psycho-
989
+ logical), which intend to define normal health as harmony and balance and
990
+ not just a fight for survival. They can be practiced in any country or culture
991
+ and offer a solution to restore normalcy and balance using soft techniques
992
+ that correct the stress pathology. We believe that this model opens up a new
993
+ holistic approach to antenatal care for women internationally.

20
+ The pandemic outbreak of coronavirus disease 2019 (COVID-19) infection caused by severe acute
21
+ respiratory syndrome-coronavirus 2 has led to profound public health crisis. In particular, individuals
22
+ with preexisting conditions of heart disease, diabetes, cerebrovascular diseases and the elderly are most
23
+ vulnerable to succumb to this infection. The current COVID-19 emergency calls for rapid development
24
+ of potential prevention and management strategies against this virus-mediated disease. There is a
25
+ plethora of evidence that supports the add-on benefits of yoga in stress management, as well as
26
+ prevention and management of chronic noncommunicable diseases. There are some studies on the
27
+ effect of yoga in communicable diseases as well but very few for acute conditions and almost none for
28
+ the rapidly spreading infections resulting in pandemics. Based on the available scientific evidences on
29
+ yoga in improving respiratory and immune functions, we have formulated very simple doable
30
+ integrated yoga modules in the form of videos to be practiced for prevention of the disease by children,
31

+ Introduction
34
+ The current outbreak of coronavirus disease 2019 (COVID-19) is an infection caused by severe acute
35
+ respiratory syndrome-coronavirus 2 (SARS-CoV-2)[1,2,3,4,5,6,7,8,9,10] with the recently analyzed
36
+ mortality of 5·7% (95% CI 5·5–5·9)[5] The initial reports of disease outbreak were reported in Wuhan,
37
+ Hubei Province of China, COVID-19 followed by its worldwide expansion[3,6,7] owing to the highly
38
+ contagious nature of the virus. In a meeting on January 30, 2020, as per the International Health
39
+ Regulations (2005), the WHO declared the outbreak as a Public Health Emergency of International
40
+ Concern as it has spread across 18 countries across the globe with four countries reporting human-to-
41
+ human transmission.[8]

47
+ Phylogenetic analysis has indicated a zoonotic origin of SARS-CoV-2,[6] with person-to-person
48
+ transmissibility.[10] SARS-CoV-2 is a β-CoV with highly identical genome to bat CoV, pointing to bat
49
+ as the natural host.[9,11] CoVs belong to a large family of single-stranded RNA viruses (+) with a
50
+ broad distribution across humans, other mammals, and birds and cause respiratory, enteric, hepatic, and
51
+ neurologic infections.[7] These RNA viruses derive their name due to the crown-like or coronal
52
+ appearance (coronam is the Latin term for crown) given by the club-shaped glycoprotein spikes in the
53
+ envelope. Importantly, the past two decades have witnessed the emergence of three highly pathogenic,
54
+ novel zoonotic CoVs – SARS-CoV (SARS-CoV now named SARS-CoV-1) discovered in November
55
+ 2002, Middle East respiratory syndrome (MERS)-CoV (MERS-CoV) in June 2012, and SARS-CoV-2,
56
+ identified in December 2019 – and have been of global public health concerns.[2,7] These periodic
57
+ emergencies occur due to frequent cross-species infections and increasing interfaces between humans
58
+ and other animal interface.[7,12] These frequent emergences also derive from the high prevalence and
59
+ wide distribution of CoVs, their large genetic diversity, and frequent recombination of their genomes.
60
+ [12]
61
+ SARS-CoV-2 causes a respiratory viral infection that represents the most prevalent and pathogenic
62
+ forms of communicable infectious diseases.[6,13] In severe cases, wherein there is a delay or absence
63
+ of early and effective antiviral treatment, the infection could manifest in a compromised systemic and
64
+ local respiratory defense mechanisms leading to bacterial coinfection culminating into severe acute
65
+ respiratory illness and occasionally into acute respiratory distress syndrome (ARDS).[7,8,9] The
66
+ current estimates indicate a basic reproduction number (R ) of 2.2, implying that on an average, each
67
+ infected person spreads the infection to an additional two persons.[14]
68
+ The latest updates suggest that the pandemic of COVID-19 has entered a new stage with rapid spread
69
+ in countries outside China indicating the need of practicing the measures for self-protection toward the
70
+ prevention of transmission of the infection to others.[4] As of March 16, 2020, a drastic escalation in
71
+ the number of cases of COVID-19 was observed outside China with a number of 143 affected
72
+ countries, states, or territories reporting infections to the WHO.[15] The COVID-19 outbreak is an
73
+ indication of the prevailing challenge of the recurrent surfacing of the unprecedented pathogenic
74
+ infections that demand regular monitoring and preparedness.[14] There is an urgent need of basic and
75
+ clinical research efforts to aid in the understanding of the disease biology and development of robust
76
+ combat measures.[14]
77
+ Clinical Course of Coronavirus Disease 2019
78
+ SARS-CoV-2 primarily spreads by droplets, and is postulated to have higher transmissibility as
79
+ compared to seasonal influenza. A major concern arises due to its likely spread via even asymptomatic
80
+ or minimally symptomatic individuals who may not seek any clinical evaluation.[16] As reported by
81
+ Huang et al., patients with COVID-19 primarily present with fever, fatigue, and dry cough.[17] Most of
82
+ the patients exhibit favorable prognosis, however, older patients and those with chronic underlying
83
+ conditions may present with worse outcomes.[17,18] In the early stages of infection, patients could be
84
+ afebrile represented with only chills and respiratory symptoms.[19] The clinical spectrum varies from
85
+ asymptomatic or mild symptomatic forms to severe forms characterized by respiratory failure that
86
+ necessitates mechanical ventilation and support in an intensive care unit (ICU) or multi-organ and
87
+ systemic manifestations in terms of sepsis, septic shock, and multiple organ dysfunction syndromes.[8]
88
+ Challenges toward the Combat of Coronavirus Disease 2019
89
+ Effective prevention or treatment of COVID-19 remains a top priority toward the curtailing of this
90
+ pandemic. Implementation of several infection control measures (e.g., social isolation, distancing, or
91
+ quarantine of entire communities) have been posited for control and prevention of the COVID-19
92
+ outbreak.[4,20] The most important and effective challenge seems to establish preventive intervening
93
+ strategies before the human–pathogen interface. Vaccination is the one of the most radical
94
+ countermeasures to combat an infectious disease epidemic. Although substantial progress has been
95
+ made toward characterization of the causative virus for COVID-19, a time period of probably a least 1
96
+ year to 18 months has been speculated for substantial vaccine production.[21] In the early stage of the
97
+ pandemic, antiviral treatment is the most effective method. Very recently hydroxychloroquine has been
98
+ 0
99
+ reported to be apparently effective against the treatment of COVID-19-associated pneumonia in clinical
100
+ studies.[22,23] However, implementation of antiviral treatment and prophylaxis has several
101
+ requirements, in particular an adequate stockpile of drugs along with the safety of the treatment and
102
+ cost-effectiveness.[24] Most importantly, the preventive/controlling measures should be implemented
103
+ in a judicious and cost-effective manner.[24]
104
+ Integrated Yoga for the Management of Noncommunicable Clinical Conditions
105
+ Yoga, an ancient mind–body technique, is defined as samatvam (balance/equipoise/homeostasis) at
106
+ both mind and body levels to be achieved through mastery over the modifications of the mind
107
+ (chittavrittinirodhah). The available evidence indicates that yoga/meditation facilitates the coordination
108
+ among the set of homeostatic responses involving the interaction among the nervous, endocrine, and
109
+ immune systems.[25] Hence, the recent definition of yoga states it as a comprehensive skill set of
110
+ synergistic process tools that aids in bidirectional feedback and modulation of autonomic nervous
111
+ system outputs through integration between central nervous system (CNS) and afferent and re-afferent
112
+ inputs from interoceptive processes such as the somatosensory, viscerosensory, and chemosensory.[25]
113
+ Postures (Sanskrit: asana), breath regulation (Sanskrit: pranayama), and meditation along with the
114
+ conceptual corrections comprise the integrative system of yoga techniques that could promote physical
115
+ as well as mental well-being. The postures or asanas are purported to have different effects. Some are
116
+ stimulatory to the nervous and circulatory systems, some develop coordination and concentration,
117
+ while others have a calming effect on the body. Some postures such as the corpse pose are used for
118
+ elongated periods of relaxation.
119
+ Clinically, these therapeutic techniques of yoga have been reported to be beneficial against the
120
+ management of acute stress as in posttraumatic stress disorder after tsunami[26] or in chronically
121
+ stressed people with depression or anxiety[26,27,28] and in many noncommunicable diseases such as
122
+ asthma,[29,30] hypertension,[31,32] heart disease,[33] and diabetes.[34,35,36,37,38] In particular,
123
+ yoga has been repeatedly reported to facilitate the attainment of glycemic control and mitigate the
124
+ influence of other risk factors associated with the complications in patients with diabetes as compared
125
+ to control conditions. It has been proposed that the abdominal pressure created during exhalation in
126
+ Kapalabhati improves the efficiency of β-cells of the pancreas.[35] It can be further viewed as
127
+ modulated interoception or sensory modulation evoked by the vigorous practice of Kapalabhati aids in
128
+ the increased interoception of the abnormal glycemic control that is signaled through the sensory inputs
129
+ of the CNS that in turn modulates the autonomic outputs to the pancreas and other organs related to
130
+ disease pathophysiology.
131
+ Insights from Clinical Evidence on Efficacy of Yoga/Meditation against
132
+ Communicable Disease Settings
133
+ There is evidence for the beneficial effects of yoga as an add-on strategy for the management of
134
+ communicable diseases including influenza,[39,40] tuberculosis (TB),[41] and human
135
+ immunodeficiency virus (HIV) infection,[42,43,44] wherein status of immune system is an important
136
+ factor that determines the progression of the disease. The results from the Meditation or Exercise for
137
+ Preventing Acute Respiratory Illness Trial (MEPARI) trial indicated that training in meditation evoked
138
+ a larger reduction in global acute respiratory infection (ARI) severity as compared to exercise or the
139
+ wait-list control participants.[39,40] The findings of the study were found to be in concordance with
140
+ prior literature on beneficial effects of moderate-intensity exercise against immune system and
141
+ reduction in the incidence of ARI illness.[39]
142
+ Similarly, a prospective, randomized trial compared the efficacy of two programs (yoga and breath
143
+ awareness) as an add-on to anti-TB treatment in sputum-positive cases in a sanatorium in Bangalore.
144
+ [41] A total of 1009 pulmonary TB patients were screened and 73 were alternately allocated to yoga (n
145
+ = 36) or breath awareness (n = 37) groups. At the end of 2 months, the yoga group showed a
146
+ significantly better reduction in symptom score and an increase in weight and lung capacity with an
147
+ improved level of infection control and radiographic image as compared to the nonyoga group.
148
+ Effect of 1 month of integrated yoga (IY) intervention has reported to significant improvement in the
149
+ psychological states as well as in the viral loads in patients suffering from HIV-1 infection.[42] Further,
150
+ yoga has also been reported to be an effective intervention for stress management and improvement in
151
+ psychological health among HIV/AIDS patients.[42,43,44] These findings indicate toward a potential
152
+ complementary role for yoga in the management of communicable diseases.
153
+ Yoga for the alleviation of stress induced immune deregulation and strengthening
154
+ of innate immune response-Paradigm for Viral Infections
155
+ Immunity of the host is an essential requisite to facilitate the eradication of infections. Impaired
156
+ immunity characterized by lymphopenia and elevated CRP levels is an essential clinical feature of
157
+ COVID-19.[19] Frequent representation of elderly individuals in the COVID-19-infected cases
158
+ indicates the plausible role of immunosenescence underlying their vulnerability to the infection. The
159
+ severity and outcome of the viral infection could be either an outcome of an effective cellular/innate
160
+ immune response that combats SARS-CoV-2 as observed in the patients with mild clinical signs of
161
+ infection or a state of immunosuppression that debilitates and sometimes overwhelms the host's
162
+ defense.[2] Available evidence indicates that stress modulates immune competence through
163
+ immunosuppression[45] (latency of herpesvirus as represented by the antibody titers), upper respiratory
164
+ tract infection, and wound healing time, indicating that stress causes a significant immune response
165
+ dysfunction. Both acute and chronic stressors can mediate their effects on sympathetic nervous system
166
+ and the hypothalamic–pituitary–adrenal (HPA) axis, thereby impairing antiviral immune responses and
167
+ innate immunity and deregulation of different immune parameters, primarily the inflammatory
168
+ pathways.[46,47] Fear, uncertainty, and stigmatization are psychological stress factors during public
169
+ health emergencies such as COVID-19.[48] These factors hinder appropriate medical and mental health
170
+ interventions and could serve as psychological risk factors and alter the immune function of subjects in
171
+ quarantine or health-care workers. In the context of pandemics with individuals experiencing high
172
+ levels of psychological stress, the modulation of HPA axis through practice of yoga could alleviate
173
+ stress and could aid in the strengthening of the antiviral immune responses.
174
+ Innate immunity is needed for precise regulation to eliminate the virus, otherwise will result in
175
+ immunopathology. A randomized controlled study in nonstressed young healthy students showed a
176
+ significant increase in interferon-gamma (IFN-γ) levels (a central regulator of cell-mediated immunity,
177
+ having antiviral, immune-regulatory functions) in the yoga group as compared to students who did not
178
+ do yoga.[49] On the contrary, a study by Gopal et al.[50] on students with examination stress showed a
179
+ significant reduction in the levels of IFN-γ levels after yoga as compared to the nonyoga control group.
180
+ (Academic stress, the stressful condition of students taking examination, has been proposed to be
181
+ considered as a more appropriate model of naturalistic stress in human beings as compared with
182
+ laboratory-induced stress situations). These physiological aspects of yoga-based mechanisms indicate
183
+ toward the buffering effect of the yoga that aids in restoring the imbalance characterized by either
184
+ suboptimum or excessive expression of immune responses. Based on its ability to induce and precisely
185
+ regulate the IFN-γ levels, yoga could boost innate immune responses during the incubation and
186
+ nonsevere stages to eliminate the virus.[51] Interestingly, these preliminary observations point to the
187
+ phenomenon of samatvam or shift toward homeostasis by the holistic approach of IY on the human
188
+ immune system and all other physiological functions. Further, practice of yoga has been associated
189
+ with increased immune surveillance in terms of the modulation of the frequency of blood lymphocytes.
190
+ [46] Infante et al. reported that in transcendental meditation (TM) practitioners, count of
191
+ CD3+CD4−CD8+ lymphocytes (P < 0.05), B-lymphocytes (P < 0.01), and natural killer (NK) cells (P
192
+ < 0.01) was higher as compared to the control group.[52] Kamei et al. reported a significant correlation
193
+ between the frontal alpha wave activation and the increase in NK activity during yoga exercises.[53]
194
+ NK cells are innate lymphocytes that serve as the first line of defense against invading viruses limiting
195
+ their spread and subsequent tissue damage. Further, Tooley et al. reported significantly higher plasma
196
+ melatonin levels in mediators practicing TM-Sidhi.[54] Melatonin is known to regulate cellular as well
197
+ as humoral immunity and stimulates the production of NK cells. A study on 96 women with breast
198
+ cancer, who participated in a MBSR program for 8 weeks, showed restoration of their NK cell activity
199
+ and IFN-γ levels as compared to continued deregulation in the non-MBSR group.[55] In addition,
200
+ postyoga increases in IgA (an antibody isotype central to mediating mucosal immunity) in pregnant
201
+ women support the protective potential of yoga against invading pathogens.[56] As mentioned above,
202
+ the immunity scores (CD4 counts) of HIV patients have been reported to improve with yoga practice.
203
+ [42] Overall, these studies indicate that practice of yoga might strengthen cell-mediated or mucosal
204
+ immunity and could be used as a preventive measure against virus or other pathogen-mediated
205
+ infections.
206
+ Yoga for alleviation of erratic immune responses
207
+ The available evidence supports the potential of yoga as a complementary intervention for populations
208
+ at risk or already suffering from diseases with an inflammatory component.[46] Several evidences
209
+ indicate that yoga might influence chronic inflammatory state and might optimize impaired immune
210
+ function in stress-induced conditions.[46] The available evidence also uniformly supports that yoga
211
+ practice could downregulate pro-inflammatory markers. Among its influence on pro-inflammatory
212
+ markers, significant decreases in interleukin-1 (IL-1) beta, as well as indications for reductions in IL-6
213
+ and tumor necrosis factor (TNF)-alpha, have been indicated.[46] Cytokine storm represented by
214
+ increased cytokine levels (IL-6, IL-10, and TNF-α), lymphopenia (in CD4 and CD8 T-cells), and
215
+ decreased IFN-γ expression in CD4 T-cells is associated with severe COVID-19.[57] These findings
216
+ support the utility of yoga as a complementary intervention for populations at risk or already suffering
217
+ from COVID-19. Duration of the yoga intervention could significantly influence the effects of yoga
218
+ practice on inflammatory markers. Based on the findings of Pullen et al.,[33] in populations with a high
219
+ risk of increased inflammation such as heart failure, shorter course of interventions of only 8 weeks has
220
+ been suggested to be sufficient to reduce inflammatory processes. The authors have indicated that a
221
+ reciprocal influence of duration of intervention required depends on the severity or deviation from
222
+ normal physiology.[33]
223
+ Integrated Yoga for the Management of Coronavirus Disease 2019 with
224
+ Comorbidities
225
+ Respiratory tract infections are highly prevalent in patients with diabetes as compared to those without
226
+ diabetes.[58] Extending on the same note, prevalence of diabetes has also been reported to be one of
227
+ the most distinctive comorbidities in patients with COVID-19; in the study by Xiaobo Yang et al. 22%
228
+ of the non-survivor critically ill COVID-19 patients were reported to have diabetes.[59] This highly
229
+ prevalent association between diabetes and COVID-19 could be attributed to the compromised immune
230
+ function, reduced T-cell response, reduced neutrophil function, and disorders of humoral immunity.[58]
231
+ Further, the hyperglycemic environment in these patients could also increase the virulence of
232
+ pathogens, lower the production of interleukins in response to infection, with reduced chemotaxis and
233
+ phagocytic activity, and immobilization of polymorphonuclear leukocytes.[58] As mentioned above,
234
+ fear, uncertainty, and stigmatization are psychological stress factors during public health emergencies
235
+ such as COVID-19.[48] The stress-induced activation of the HPA axis could also significantly
236
+ contribute to poor glycemic control (hyperglycemia),[35] thereby exacerbating the clinical symptoms.
237
+ The stress-reducing aspects of yoga through modulation of HPA axis in patients with aberrant glycemic
238
+ control (diabetes and prediabetes) could aid in the attainment of glycemic control as has been
239
+ frequently reported.[34,35,36,37,38] The practice of yoga might aid in reducing the exacerbations and
240
+ clearance of virus infection in COVID-19 patients with diabetes through reducing the influence of
241
+ systemic hyperglycemic and inflammatory milieu.
242
+ Similarly, hypertension is also a distinct comorbidity of COVID-19 infection.[60] A study by Guan et
243
+ al. on 1099 patients with confirmed COVID-19 reported the high prevalence of comorbidities of
244
+ hypertension (23·7%) and diabetes mellitus (16·2%) in 173 severe cases.[60] Hypertension is typically
245
+ treated with drug inhibitors that target the renin–angiotensin system (RAS).[18,61] These drugs are
246
+ mainly the angiotensin-converting enzyme inhibitors (ACEIs) or angiotensin receptor blockers (ARBs).
247
+ These RAS inhibitors have been well established against the effective management of blood pressure
248
+ (BP) as well as protection from disease-associated inflammation. However, RAS inhibitors have been
249
+ postulated to affect the expression of ACE2 mRNA and the activity of ACE2 in tissues.[18,61] ACE2
250
+ is a key counterregulatory enzyme of ACE that degrades angiotensin II to angiotensin-(1–7), thereby
251
+ attenuating the effects on vasoconstriction, sodium retention, and fibrosis,[62] although there have been
252
+ no definitive conclusions regarding the association of COVID-19 with RAS inhibitors. ACE2 has been
253
+ +
254
+ +
255
+ +
256
+ proposed to be a likely cellular receptor of COVID-19,[62] and in vitro findings have been reported
257
+ that the receptor mediates the entry of COVID-19 virus into HeLa cells.[63] Further long-term use of
258
+ ACEIs might suppress the adaptive immune response, which is a key defense against viral infection.
259
+ [61]
260
+ Yoga and meditation, in particular slow deep breathing, have been reported to decrease sympathetic
261
+ nervous system activity, and increase the baroreflex sensitivity in hypertensive patients, thereby
262
+ reducing their blood pressure values.[64] Modulation of HPA axis and autonomic outputs including BP
263
+ has also been reported to underlie its physiological effects of yoga.[64] However, there has been a lack
264
+ of evidence on specific targeting of RAS or its effector components through yoga. Inflammatory
265
+ systematic milieu in hypertensive patients with already altered autonomic regulations could exacerbate
266
+ disease outcomes. Based on the anti-inflammatory potential of yoga in hyperinflammatory settings
267
+ such as hypertension, we further extend that yoga could reduce the clinical nonfavorable outcomes in
268
+ hypertensive patients. Further, a Class II-A level of Evidence B recommendation for BP-lowering
269
+ efficacy has been conferred on slow breathing.[65] Hence, yoga/slow breathing techniques could
270
+ provide a safe adjunct/complementary approach for the management of hypertension in COVID-19
271
+ patients with hypertension.
272
+ Yoga for Better Respiratory Capacity
273
+ There is a plethora of evidence that breathing exercises have beneficial effects on the respiratory
274
+ system.[66] Pranayama, a yoga-based respiratory exercise, is a simple and cost-effective intervention
275
+ that could be easily integrated in daily routine and has been proven beneficial in subjects across
276
+ different age groups including the elderly.[67] Yoga training has been reported to improve strength of
277
+ expiratory as well as inspiratory muscles.[68] Joshi et al. reported beneficial effects of a 6-week course
278
+ of pranayama on ventilatory lung functions.[69] The authors reported improved ventilatory functions
279
+ with respect to lowered respiratory rate (RR) and increased forced vital capacity (FVC), forced
280
+ expiratory volume at the end of 1 s (FEV1%), maximum voluntary ventilation (MVV), peak
281
+ expiratory flow rate (PEFR), and prolongation of breath-holding time.[69] Repeated practice of
282
+ pranayama has been shown to strengthen cardiorespiratory coupling and increases in the
283
+ parasympathetic activity in healthy individuals.[64] The breathing practice called Kapalabhati is
284
+ comprised of powerful strokes of exhalations accompanied with the contraction of abdominal and
285
+ diaphragmatic muscles followed by passive inhalations.[70] Kapalabhati aids in appropriate training
286
+ and toning of diaphragm and abdominal muscles. It also helps in removal of secretions from bronchial
287
+ tree, cleansing up respiratory passages and the alveoli.[70] A combination of yogic breathing
288
+ techniques improved the pulmonary functions in competitive swimmers.[71]
289
+ Yoga Practice and Chronic and Acute Respiratory Distress
290
+ There have been several reports of clinical trials that suggest an overall effect of yoga training toward
291
+ improved pulmonary function in patients with chronic obstructive pulmonary disease (COPD),
292
+ [72,73,74,75,76,77] an important cause of morbidity and mortality, and poses a major public health
293
+ problem. When meta-analyzed, a significant clinical effect of yoga in COPD patients with respect to
294
+ FEV1 was observed.[72] In addition, the studies reported training effects of yoga on improved exercise
295
+ capacity, lung function decline, quality of life, and dyspnea in patients with COPD.[72] Several
296
+ mechanistic factors have proposed to underlie the beneficial effects seen in the patients undergoing
297
+ yoga such as increasing respiratory stamina, relaxing chest muscles, expanding the lungs, raising
298
+ energy levels, and calming the body.[72] However, due to the lack of adequate data and insufficient
299
+ clinical evidence provided by these studies, the clinical relevance of these findings needs further
300
+ thorough robust experimental evaluations.[72]
301
+ Findings of Meditation or Exercise for Preventing Acute Respiratory Illness Trial –
302
+ Paradigm for viral-mediated respiratory infections
303
+ There has been a dearth of clinical evidence on influence of yoga against acute respiratory distress.
304
+ However, there have been two major relevant successive reports of MEPARI trials that tested the effect
305
+ of training in mindfulness-based stress reduction (MBSR) or sustained moderate-intensity exercise on
306
+ st
307
+ incidence, duration, severity, and impact of all-cause mortality of ARI.[39,40] MEPARI-1 reported
308
+ statistically and clinically significant reductions in ARI illness for participants randomly assigned to 8
309
+ weeks of MBSR training, compared to the observational controls. The MEPARI-2 trial was designed to
310
+ replicate and extend findings from the first MEPARI trial.[40] The authors reported a consistent pattern
311
+ of benefits across the two trials suggestive of preventive effects ranging from 14% to 33% proportional
312
+ reductions in ARI illness.[40] Very importantly, the authors presented a comparative perspective of the
313
+ findings of MEPARI trials against vaccinations against influenza.[40] Flu shots or vaccines are known
314
+ to reduce influenza, with published estimates of proportional reductions in symptomatic illness,
315
+ medical visits, and absenteeism ranging from 13% to 70%.[78,79,80,81,82] The authors Vaccinations
316
+ are disease specific; in other words, these are specific to virus strains, so the protection provided is also
317
+ specific and restrictive. However, mindfulness and exercise trainings have more generic mechanisms,
318
+ regardless of etiological agent. A recent study has reported beneficial effect of meditation on adaptation
319
+ to the hypoxic high altitude conditions that requires synergistic functioning of respiratory, cardiac, and
320
+ hematological system.[83] The authors reported increase in the partial pressure of oxygen, (PO2) a
321
+ marker of bio-availability of oxygen at the cellular levels.[83]
322
+ Pilot study on yoga module in coronavirus disease 2019
323
+ Breathing exercises using the concepts of yoga could also be adopted to help during states of acute
324
+ respiratory distress. We have previously taught an eight-stepped yoga breathing procedure consisting of
325
+ very simple neck muscle relaxation movements and asanas with breathing exercises using the support
326
+ of a chair during 110 episodes of acute airway obstruction in 86 bronchial asthma patients. There was a
327
+ significant improvement in their PEFR by >20% within 30 min of the practice with successful relief
328
+ from the episode. The patients reported reduction in panic and anxiety element, cutting the vicious
329
+ cycle of aggravating bronchial obstruction. Based on the above discussed several beneficial aspects of
330
+ yoga on the immune and respiratory systems against varied clinical settings including that of infectious
331
+ diseases, we postulate a therapeutic potential of yoga towards COVID-19 prevention and management
332
+ [Figure 1]. We have evolved age-specific sets of yoga modules [Tables 1 and 2] based on our extensive
333
+ experience of over past 35 years on clinical research on yoga. The modules have been made available
334
+ for public use on our website https://svyasa.edu.in. To this end, a pilot study was conducted on request
335
+ providing a 4-min video of very simple practices as a voluntary clinical aid to the hospitalized COVID-
336
+ 19 patients in Milano, Italy, visited by 1000 people between March 17 and 20, 2020. The report by a
337
+ cardiac surgeon who was also admitted in the intensive care unit of the Italy based hospital due to
338
+ severe COVID-19 infection stated “We have reached scientific evidence that this simplified protocol
339
+ sent by you is effective and we intend to disseminate to the overall Scientific Community”.

+ Abstract 
15
+ Background:  The ongoing novel coronavirus disease 2019 (COVID-19) pandemic has a significant mortality rate
16
+ of 3–5%. The principal causes of multiorgan failure and death are cytokine release syndrome and immune dysfunc‑
17
+ tion. Stress, anxiety, and depression has been aggravated by the pandemic and its resultant restrictions in day-to-day
18
+ life which may contribute to immune dysregulation. Thus, immunity strengthening and the prevention of cytokine
19
+ release syndrome are important for preventing and minimizing mortality in COVID-19 patients. However, despite a
20
+ few specific remedies that now exist for the SARS-CoV-2virus, the principal modes of prevention include vaccina‑
21
+ tion, masking, and holistic healing methods, such as yoga. Currently, extensive research is being conducted to better
22
+ understand the neuroendocrinoimmunological mechanisms by which yoga alleviates stress and inflammation. This
23
+ review article explores the anti-inflammatory and immune-modulating potentials of yoga, along with its role in reduc‑
24
+ ing risk for immune dysfunction and impaired mental health.
25
+ Methods:  We conducted this narrative review from published literature in MEDLINE, EMBASE, COCHRANE databases.
26
+ Screening was performed for titles and abstracts by two independent review authors; potentially eligible citations
27
+ were retrieved for full-text review. References of included articles and articles of major non-indexed peer reviewed
28
+ journals were searched for relevance by two independent review authors. A third review author checked the excluded
29
+ records. All disagreements were resolved through discussion amongst review authors or through adjudication by a
30
+ fourth review author. Abstracts, editorials, conference proceedings and clinical trial registrations were excluded.
31
+ Observations:  Yoga is a nonpharmacological, cost-effective, and safe intervention associated with several health
32
+ benefits. Originating in ancient India, this vast discipline consists of postures (asanas), breathing techniques (pranay‑
33
+ ama), meditation (dhyana/dharana), and relaxation. Studies have demonstrated yoga’s ability to bolster innate immu‑
34
+ nity and to inhibit cytokine release syndrome. As an intervention, yoga has been shown to improve mental health, as

+ Introduction
69
+ Coronavirus disease (COVID-19) is a highly contagious
70
+ viral disease that has affected 238,349,712 people world-
71
+ wide as of October 9, 2021. Its outbreak was initially
72
+ reported in 2019 in Wuhan, Hubei Province, China.
73
+ Nearly 5 million deaths had been reported worldwide
74
+ as of the first week of October 2021. Many countries are
75
+ still “locked down” to prevent extensive spread of infec-
76
+ tion, whereas others have relaxed these measures; even
77
+ so, social isolation measures are still generally recom-
78
+ mended, at least to some extent. Many argue that easing
79
+ social restrictions has contributed to spikes in the num-
80
+ ber of cases nationwide [1–5].
81
+ Given the limited treatment options and the emer-
82
+ gence of multiple strains with variable susceptibility to
83
+ vaccines, clinicians are searching for other interventions
84
+ to aid in the prevention and treatment of COVID-19.
85
+ In the context of integrative medicine, yoga is a mind-
86
+ body discipline that promotes healthy living through
87
+ various components, such as the practice of postures
88
+ (asana), breathing techniques (pranayama), concentra-
89
+ tion (dharana), and meditation (dhyana) [2, 6]. A grow-
90
+ ing body of evidence suggests that yoga practice leads to
91
+ better integrative management of a number of non-com-
92
+ municable diseases that share the same pathophysiology,
93
+ including cardiovascular diseases, stroke, and diabetes
94
+ mellitus type II. The underlying reasoning is that these
95
+ diseases, like COVID-19, express rogue immunologi-
96
+ cal aberration, resulting in many of their manifestations,
97
+ which are often triggered or exacerbated by stress [2,
98
+ 7]. A meta-analysis of ten randomized controlled trials
99
+ including 431 individuals suggested that yoga programs
100
+ improved exercise capacity (mean change 2.69, 95% con-
101
+ fidence interval 1.39- 3.99) and health related quality of
102
+ life (mean change 1.24, 95% confidence interval − 0.37-
103
+ 2.85) among patients with chronic ailments namely heart
104
+ disease, chronic obstructive pulmonary disease and
105
+ stroke when compared with normal care [8]. Consistent
106
+ practice of yoga strengthens innate and adaptive immu-
107
+ nity and helps to enhance physiological functions, such
108
+ as respiration, digestion, circulation, and hormone pro-
109
+ duction [2, 9–11].
110
+ In this review article, we discuss inflammatory, infec-
111
+ tious, and psychosocial aspects of COVID-19 and
112
+ explore the anti-inflammatory and immune-modulating
113
+ potentials of yoga, along with its role in reducing risk fac-
114
+ tors for immune dysfunction and impaired mental health.
115
+ We propose yoga as an intervention for expediting recov-
116
+ ery in patients with COVID-19 and for enhancing innate
117
+ immunity and mental health to bolster resistance to the
118
+ virus [2].
119
+ Methods
120
+ We conducted this narrative review from published lit-
121
+ erature in MEDLINE, EMBASE, and COCHRANE data-
122
+ bases. Articles were retrieved from database searches
123
+ using keywords related to complementary therapy,
124
+ COVID-19, immunomodulation, psychological stress,
125
+ and yoga. Observational and experimental studies and
126
+ discussing the role of yoga in anxiety, immunomodula-
127
+ tion, and COVID-19 were considered relevant for this
128
+ narrative review. Screening was performed for titles and
129
+ abstracts by two independent review authors; poten-
130
+ tially eligible citations were retrieved for full-text review.
131
+ References of included articles and articles of major
132
+ non-indexed peer reviewed journals were searched for
133
+ relevance by two independent review authors. A third
134
+ review author checked the excluded records. All disa-
135
+ greements were resolved through discussion amongst
136
+ review authors or through adjudication by a fourth
137
+ review author. Abstracts, editorials, conference proceed-
138
+ ings and clinical trial registrations were excluded. Only
139
+ articles in English language were included.

142
+ an acute infectious agent that enters the body through
143
+ the respiratory system. Droplet transmission is under-
144
+ stood to be the primary mode of transmission. Mounting
145
+ evidence also suggests airborne transmission, although
146
+ the World Health Organization has yet to confirm this.
147
+ A person can become infected when his or her mucus
148
+ membrane (within the nose, eyes, or mouth) comes into
149
+ contact with the respiratory secretions of an actively
150
+ infected person discharging virus particles. Having
151

152
+ to bind angiotensin-converting enzyme (ACE)-2 recep-
153

163
+ expressed primarily in both type I and type II pneumo-
164
+ cytes but also in other types of cells, including endothe-
165
+ lial cells. Thus, it plays a vital role in vascular integrity
166
+ and hemodynamic regulation [12–14].
167
+ Evidence indicates that cardiac involvement is ubiqui-
168
+ tous in patients with COVID-19, particularly in hospi-
169
+ talized patients [14]. Patients with cardiac risk factors or
170
+ established cardiovascular disease have heightened vul-
171
+ nerability, along with worse mortality and morbidity pro-
172
+ files. In various studies, nearly 30% of afflicted patients
173
+ had hypertension and 15% had preexisting cardiovascular
174
+ disease [15, 16].
175
+ Role of immunity in COVID‑19
176
+ The human immune system comprises multiple organs,
177
+ such as the spleen, thymus, lymph nodes, tonsils, and
178
+ bones. Immune cells and their products destroy the
179
+ intruding infective organisms and neutralize them. The
180
+ immune system includes both innate immunity and
181
+ adaptive immunity. Innate immunity is the rapid-act-
182
+ ing first line of defense that effectively inhibits infec-
183
+ tive agents from entering the body. However, if this line
184
+ of defense fails, the immune system activates adaptive
185
+ immunity, which is important to control most viral infec-
186
+ tions. The emerging picture reveals that CD4+ T cells,
187
+ CD8+ T cells and neutralizing antibodies has important
188
+ role in COVID-19 and thus its prevention and manage-
189
+ ment [17].
190
+ Innate immunity is garnered to restrict infections by
191
+ novel pathogens, such as SARS-CoV-2. This elaborate
192
+ immunological cascade appropriately arrests the disease
193
+ and helps to initiate the repair mechanism, thus ensur-
194
+ ing satisfactory resolution of the infection and generating
195
+ targeted resistance to defend the body against reinfection
196
+ by the same organism [18]. The adaptive immune system
197
+ involves T lymphocytes, B lymphocytes, and pathogen-
198
+ specific antibodies in addition to the proinflammatory
199
+ cytokines and chemokines that help to eliminate the
200
+ pathogen [19]. Although these processes are very potent
201
+ and effective, they can render bystander damage to the
202
+ body’s own cells and organs.
203
+ Infection with COVID-19 presents with three dif-
204
+ ferent clinical scenarios: (1) asymptomatic carriers
205
+ who have adequately functioning innate immunity;
206
+ (2) symptomatic carriers with mild symptoms who
207
+ achieve spontaneous recovery as their innate immu-
208
+ nity detects infection and restricts it, while generating
209
+ adaptive immunity that optimally gets rid of the virus;
210
+ and (3) patients who develop moderate to severe illness
211
+ and either recover or die from the infection [20]. In this
212
+ third category of patients, the body’s immune system,
213
+ in both its innate and adaptive expressions, is activated.
214
+ In those who die, the immune system is overwhelmed,
215
+ leading to cytokine release syndrome (CRS), a massive,
216
+ cascading release of cytokines that initiates widespread
217
+ destruction and multiorgan failure, ultimately leading to
218
+ death [13]. In essence, the virus does not directly kill but
219
+ instead initiates an immunological reaction that is mor-
220
+ bid and occasionally fatal (Fig. 1). It is therefore unfortu-
221
+ nate that the resources harnessed by the body to kill the
222
+ virus largely outweigh the appropriate levels needed and
223
+ instead produce tissue destruction, organ failure, and
224
+ eventually death. Interleukin (IL)-6 is the primary can-
225
+ didate cytokine suspected of perpetrating this fatal reac-
226
+ tion [14, 15]. This knowledge has spawned initiatives to
227
+ block IL-6 using receptor inhibitors, including biologics
228
+ like tocilizumab, which are undergoing trials in moder-
229
+ ately to severely ill patients with COVID-19 [19].
230
+ An optimal innate immune response may thus play
231
+ a vital role in the prevention and early disposal of most
232
+ COVID-19 infections. A response of this nature is
233
+ believed to occur in 80% or more of those infected, who
234
+ either are asymptomatic or develop mild symptoms that
235
+ defervesce and culminate in an uneventful recovery. The
236
+ precise cause of immune dysfunction and CRS led by the
237
+ overproduction of IL-6 is unknown. Nonetheless, con-
238
+ siderable evidence points to the fact that the severity of
239
+ the disease is based on the immune response to the virus,
240
+ among other factors [22].
241
+ Pandemics, immunity, and mental health
242
+ Remdesivir, the antiviral agent effective against COVID-
243
+ 19, only shortens the illness timetable by around 33%
244
+ [23]. The antiviral treatments recently approved by the
245
+ FDA would lead to resistance if randomly used. Moreo-
246
+ ver, their efficacy is not absolute and is only effective if
247
+ started early in the course of the infection. These limita-
248
+ tions render preventive measures—including vaccina-
249
+ tion, hygiene, social distancing, and personal protective
250
+ equipment—to be the primary means of managing the
251
+ COVID-19 pandemic. Social distancing through par-
252
+ tial or complete lockdowns often leads to psychological
253
+ issues such as anxiety, depression, and panic attacks—all
254
+ of which are known to downregulate the immune system
255
+ [2, 24]. Associated economic downturns, featuring job
256
+ losses and financial hardships, have accentuated mental
257
+ health issues during the pandemic [25]; suicides, opioid
258
+ overdoses, and domestic violence also have increased.
259
+ When vulnerable persons such as children, pregnant
260
+ women, or elderly relatives are part of the household,
261
+ stress and anxiety levels appear to worsen, given the
262
+ higher disease severity and mortality rates in these
263
+ groups. The conglomeration of stress states is associated
264
+ with downregulation of immunity and, consequently,
265
+ with worsened disease manifestations.

268
+ Stress
269
+ Both chronic and sub-acute stress have a significant
270
+ negative impact on the immune system [26]: on the
271
+ one hand, the ability to cope with stress helps preserve
272
+ immune function; on the other hand, individuals with
273
+ higher stress levels and poor coping mechanisms have
274
+ subpar immunity. Lower resilience to stress is associated
275
+ with poor antibody response and decreased natural-killer
276
+ cell activity [27, 28].
277
+ Stress affects immune function by increasing glucocor-
278
+ ticoid and catecholamine secretion. Stress also induces
279
+ chronic sympathetic overdrive as it simultaneously
280
+ attenuates the parasympathetic system [29]. Escalated
281
+ sympathetic drive with its attendant hormonal milieu
282
+ (including cortisol excess and a robust catecholaminergic
283
+ drive) attenuates the efficacy of the immune system [30].
284
+ The aberrant pathophysiology at play under such condi-
285
+ tions is increased inflammation and decreased protection
286
+ against invading microorganisms [30]. Increased gluco-
287
+ corticoid levels significantly affect the immune function
288
+ by dysregulating cytokine production, affecting natural-
289
+ killer cell activity and reducing immunoglobulin A (IgA)
290
+ production [30]. Elevated cortisol potentiates glucose
291
+ intolerance and diabetes and thus further increases the
292
+ risk for infection [31]. Moreover, evidence suggests that
293
+ people who have stressful life events have greater risk for
294

299
+ respiratory infections [32]. The higher stress levels asso-
300
+ ciated with extended lockdowns and the concomitant
301
+ fear, anxiety, and depression lead to weakened immunity,
302
+ opening the floodgates of infection [33].
303
+ The paradoxical response of augmented inflammation
304
+ that is elicited during stress despite increased corticos-
305
+ teroid levels in the blood is not clearly delineated. After
306
+ all, chronic stressors should ameliorate the symptoms
307
+ of inflammation-related diseases, but this conclusion is
308
+ at odds with the excess morbidity and mortality docu-
309
+ mented in chronically stressed individuals. Miller and
310
+ colleagues [34] have put forth an alternative hypothesis
311
+ that posits the development of macrophage resistance to
312
+ cortisol negative feedback under conditions of chronic
313
+ stress, due to compensatory downregulation at the
314
+ immune cell (glucocorticoid) receptor. Early life stress
315
+ can give rise to blunted cortisol negative feedback of the
316
+ innate inflammatory response [35]. This may set the stage
317
+ for the stress-related chronic inflammation thought to
318
+ lower the threshold for stress-related noncommunicable
319
+ disease [36]. However, the research establishing cell sur-
320
+ face receptor compensatory changes under conditions of
321
+ stress has thus far been unimpressive. Further research
322
+ is needed to discern the probable mechanism for this
323
+ phenomenon.
324
+ Depression
325
+ During lockdowns, social isolation and lack of physical
326
+ activity are two prominent risk factors for depression.
327
+ Depression increases the risk ofCOVID-19 infection sig-
328
+ nificantly. There was increased mortality and hospitali-
329
+ zation rates among COVID-19 infected patients having
330
+ recently diagnosed depression [37].
331
+ Compared with nondepressed cohorts, individu-
332
+ als with recently diagnosed depression were found to
333
+ have a significantly higher risk for COVID-19 infec-
334
+ tion (Adjusted Odds Ratio 7.64, 95% confidence interval
335
+ 7.45- 7.83) [35, 36]. Depression is correlated with altera-
336
+ tion in immune markers, including decreases in mitogen
337
+ proliferation, natural-killer cell activity, and the types
338
+ and respective quantities of antibodies produced [38].
339
+ Depression also dysregulates the neuroendocrine system
340
+ [39] and consequently increases inflammation, altering
341
+ the immune system’s effectiveness while simultaneously
342
+ increasing bystander damage [40]. Patients with depres-
343
+ sion have disrupted T-cell function and elevated levels of
344
+ cytokines, such as tumor necrosis factor (TNF)-α, IL-1,
345
+ and IL-6 [40].
346
+ Anxiety
347
+ Pandemics are associated with heightened anxiety, on
348
+ both the collective and individual levels. The highly con-
349
+ tagious nature of COVID-19 and the lack of treatment
350
+ options add to the increased threat to survival and may
351
+ trigger or aggravate existing anxiety and panic disorders.
352
+ Anxiety contributes to significant dysfunction in
353
+ immune function by dysregulating the hypothalamic-
354
+ pituitary-adrenal (HPA) axis [41, 42]. In a study of 42
355
+ patients with panic disorder and 42 healthy individuals,
356
+ Koh and Lee observed significantly lower IL-2 produc-
357
+ tion and lymphocyte proliferation levels in patients with
358
+ anxiety disorder than in those without [43]. Complex
359
+ changes in the inflammation milieu related to aberrant
360
+ cytokines, particularly IL-1β, IL-6, TNF-α, and interferon
361
+ (IFN)-γ, have been documented in anxiety-based disor-
362
+ ders [44]. Furthermore, patients with anxiety disorder
363
+ exhibit lower CD4+ cell counts, compared with healthy
364
+ controls. Studies have also documented the elevation of
365
+ suppressor CD8+ cells in these conditions, along with
366
+ a potentiated cytokine response [45]. This abnormal
367
+ response of the body’s immunological system in anxiety
368
+ and depression may contribute to heightened infection
369
+ and mishandling of severe infection, leading to a magni-
370
+ fied, self-damaging cytokine response [46].
371
+ Yoga and immunity
372
+ Yoga is noted to have a positive impact on the immune
373
+ system [47–49] and inflammation pathways (Table  1).
374
+ It reduces inflammation and increases the number and
375
+ activity of natural-killer cells [50–52], thus enhancing
376
+ cell-mediated cytotoxicity of invading infective agents.
377
+ Evidence shows that yoga practice is associated with
378
+ improvement in CD3+ and CD4+ cell counts, salivary
379
+ cortisol levels, and IgA [53], a dominant player in innate
380
+ immunity that is present on body linings, such as those of
381
+ the lungs and the gastrointestinal tract [54]. With yogic
382
+ intervention, IgA levels increase at the exposed lung bor-
383
+ der, where type II pneumocytes are prevalent. Addition-
384
+ ally, cortisol, which dampens the body’s ability to fight
385
+ infection, is decreased by practicing yoga.
386
+ Yoga has been found to be effective in immunocompro-
387
+ mised conditions such as HIV. It helps to improve CD4+
388
+ count and anxiety, depression, and stress among patients
389
+ with HIV [47, 56]. It has found to be equally effective in
390
+ improving CD56+ cell count, anxiety, and depression in
391
+ chronic disorders such as cancer [51].
392
+ The cytokine storm unleashed by the body’s unregu-
393
+ lated response to SARS-CoV-2 induces multiorgan
394
+ damage, resulting in high morbidity and mortality.
395
+ Myocarditis with severe refractory acute heart failure
396
+ has been noted [57]. As myocarditis is a clear signal for
397
+ cytokine-mediated damage, direct damage by the SARS-
398
+ CoV-2 virus cannot be discounted, as both the heart and
399
+ vascular endothelium express the ACE2 receptors that
400
+ are entry gates for COVID-19 [13]. Cytokine profiles
401
+ in patients diagnosed with COVID-19 showed marked

619
+ elevation of T-helper lymphocyte type 1, IFN-γ, and
620
+ inflammatory cytokines IL-1β, IL-6, and IL-12 for at least
621
+ 2 weeks after disease onset [58]. Among these, IL-6 is a
622
+ predictor of mortality in COVID-19 patients, which may
623
+ explain why primary evidence suggests that IL-6 inhibi-
624
+ tors have shown promise as treatments [2, 59].
625
+ Nagarathna et al. have documented the downregulation
626
+ of pro-inflammatory markers by yoga in their review arti-
627
+ cle, hence supporting the utility of yoga as a complemen-
628
+ tary intervention for subjects at risk or already infected
629
+ by SARS-CoV-2 virus [60]. Evidence indicates that yoga
630
+ practice helps to reduce inflammation by downregulating
631
+ a vast array of initiators and modulators that perpetuate
632
+ chronic inflammation, including IL-6, TNF-α, and IL-1β
633
+ [59, 60].
634
+ Multiple randomized controlled trials have docu-
635
+ mented a significant reduction in IL-6 levels in yoga
636
+ groups as compared with controls [61]. In one study,
637
+ researchers observed a significant reduction in IL-6 at
638
+ the 3-month follow-up in breast cancer patients who
639
+ practiced yoga, compared with a non-yoga control group
640
+ [62]. Moreover, increasing the amount of yoga practice
641
+ led to a more pronounced decrease in IL-6, pointing
642
+ towards a potential dose-response effect. Another rand-
643
+ omized trial showed significantly reduced IL-6 secretion
644
+ after yoga practice in healthy individuals and significantly
645
+ reduced secretion of IL-6 when cultured blood was chal-
646
+ lenged with a toll-like receptor agonist [62]. Multiple
647
+ studies have substantiated the beneficial effect of yoga on
648
+ inflammation and how it leads to CRS reduction, if not
649
+ inhibition (Table 2).
650
+ Yoga during stressful events
651
+ Various clinical trials have suggested a significant role for
652
+ yoga in reducing depression and its associated variables
653
+ (Table  3). In one study, 16 distressed women received
654
+ 3 months of Iyengar yoga intervention, and a group of
655
+ 8 women served as a control. After 3 months, women
656
+ in the yoga group showed a significant decrease in per-
657
+ ceived stress, depression, and anxiety and in salivary cor-
658
+ tisol; well-being improved significantly in the yoga group,
659
+ compared with controls [65].
660
+ Yoga practice helps adherents to develop a positive
661
+ attitude during stress and to enhance self-awareness and
662
+ coping ability (Fig. 2). Yoga (asana, pranayama, and medi-
663
+ tation) improves calmness and mindfulness and increases
664
+ an individual’s awareness and self-control [52]. Hatha
665
+ yoga (a variation in which only yoga postures are prac-
666
+ ticed, with little or no meditation) improves HPA axis
667
+ dysregulation, corrects autonomic balance, and enhances
668
+ homeostasis by hastening recovery from stress [66].
669
+ In a study among 131 participants with mild to moder-
670
+ ate stress levels, 10 weeks of a Hatha yoga intervention
671
+ resulted in significant decreases in stress and anxiety,
672
+ along with enhanced relaxation [70]. In another study,
673
+ 90-minute Hatha yoga sessions led to a significant reduc-
674
+ tion in titers, negative affect, and cortisol levels [2, 72].
675
+ Yoga helps to reduce the allostatic load of the stress
676
+ response [73]. It reduces sympathetic overactivity and
677
+ improves parasympathetic tone during a stressful situ-
678
+ ation, as indicated by oxygen consumption level, heart
679
+ rate, and the high-frequency component of heart rate
680
+ variability [69].
681
+ In a meta-analysis by Cramer et  al., yoga was found
682
+ to be an effective intervention for improving depression
683
+ [68]. Multiple studies have confirmed that yoga prac-
684
+ tice reduced depression and improved mood and cog-
685
+ nitive function among patients with mild to moderate
686
+ depression. This is achieved by enhancing the HPA axis
687
+ function, increasing brain-derived neurotrophic factor
688
+ (BDNF) levels and serotonin levels, and decreasing cor-
689
+ tisol and inflammatory markers [68, 74, 75]. Autonomic
690
+ dysfunction is a hallmark of both anxiety and depres-
691
+ sion [76]; regular yoga practice of pranayama can help
692
+ improve autonomic balance by decreasing sympathetic
693
+ overactivity and improving parasympathetic activity
694
+ [69]. Yoga also enhances the γ-aminobutyric acid system,
695
+ which is implicated in anxiety and depression [69].
696
+ Yoga also improves various cognitive facets, such as
697
+ attention, concentration, memory, and executive func-
698
+ tioning [71]. By improving body awareness, feelings, and
699
+ thoughts, yoga facilitates the experience of body sensa-
700
+ tions in a nonjudgmental way [77]. It also enables the
701
+ practitioner to focus on present experience instead of
702
+ ruminating over future or past worries [78]. Self-aware-
703
+ ness aids in avoiding addictive or overindulgent behav-
704
+ iors, including overeating and excess sleeping. Yoga helps
705
+ people remain active and fosters a positive attitude dur-
706
+ ing a lockdown.
707
+ Cardio‑respiratory protective effects of yoga
708
+ Given the severe cardiorespiratory illness manifested
709
+ in COVID-19 [1], consistent training in yoga may play
710
+ a protective role. Yoga has numerous positive effects
711
+ on the cardiovascular and respiratory systems. It has
712
+ been proven to improve various forms of cardiac
713
+ arrhythmia, congestive cardiac failure, ischemic heart
714
+ disease, and hypertension [79–83]. Regular yoga prac-
715
+ tice attenuates systolic and diastolic blood pressure
716
+ and mean arterial pressure; it has also been credited
717
+ with maintaining appropriate blood pressure with less
718
+ medication [84]. Simply lying down in the Savasana
719
+ yogic posture for 20 minutes daily was found to be
720
+ effective in reducing systolic and diastolic blood pres-
721
+ sure and the need for antihypertensive medication
722
+ [85]. Yoga has been shown to improve cardiac function

874
+ to improve baroreflex sensitivity, peripheral vascu-
875
+ lar resistance, and heart rate variability [87]. It also
876
+ helps to attenuate catecholamine secretion, which has
877
+ been implicated in the etiology of severe cardiomyo-
878
+ pathy and heart failure [88]. In one study, 8 weeks of
879
+ yoga intervention led to significant decrease in IL-6,
880
+ C-reactive protein, and extracellular superoxide dis-
881
+ mutase, compared with non-yoga controls in patients
882
+ with heart failure [89]. Thus, evidence indicates that
883
+ yoga offers multi-faceted protection from cardiac
884
+ damage mitigated by aberrant cytokine release, such as
885
+ that seen with COVID-19.
886
+ Limitations
887
+ Our review is up-to-date, and the findings are of sig-
888
+ nificant relevance but the important limitations must
889
+ be considered. The literature was searched and sum-
890
+ marized thoroughly but our review was not system-
891
+ atic, thus increasing the possibilities of selection and
892
+ publication bias. Our study included only articles in
893
+ English thus introducing a language bias. The associa-
894
+ tions and characteristics identified in this review await
895
+ clearly proven causative mechanisms. Important con-
896
+ founders exist in the cross-sectional studies reviewed
897
+ in the form of age, medications, and immune strength.
898
+ Larger randomized controlled trials will provide nec-
899
+ essary insight on the role of yoga in immunomodula-
900
+ tion and mental health during the present pandemic.
901
+ Conclusions
902
+ The aggregation of pathophysiological aberrations,
903
+ both psychological and somatic, secondary to COVID-
904
+ 19 pandemic and its resultant restrictions, may increase
905
+ the severity of the infection. Accumulated evidence
906
+ leads us to hypothesize that, for many, yoga practice
907
+ may attenuate the ill effects of COVID-19–induced
908
+ immune dysfunction at different stages.
909
+ From a public health perspective, yoga represents a
910
+ low-cost, noninvasive strategy for alleviating the physi-
911
+ cal and emotional toll of the COVID-19 pandemic.
912
+ The aforementioned yoga practices can be performed
913
+ at home, in adherence to social distancing guidelines.
914
+ Outcomes from an 8-week yoga intervention (asanas,
915
+ pranayama, and meditation) indicated that medical
916
+ treatment plus yoga is more effective than medical
917
+ treatment alone in reducing anxiety [90]. Relaxation
918
+ techniques like yoga and meditation helps in managing
919
+ chronic or long term stress by regulating the cytokines,
920
+ thus assisting people to overcome co-morbidities asso-
921
+ ciated with diseases and improving the quality of life;
922
+ which is important in COVID-19 and post-COVID
923
+ illness [2, 21]. Notwithstanding, appropriate clini-
924
+ cal trials are required to document the efficacy of this
925
+ strategy.

+ ABSTRACT
9
+ Aim: To explore the needs of caregivers of inpatients with schizophrenia in India.
10
+ Material: Thirty caregivers of inpatients with schizophrenia participated in five focus
11
+ group discussions (FGD), where the needs of the caregivers were discussed. The
12
+ FGDs were recorded, transcribed and similar needs were grouped and ranked
13
+ according to their order of importance.
14
+ Discussion: The main needs that emerged were regarding: managing the behaviour
15
+ of patients; managing social-vocational problems of patients; health issues of
16
+ caregivers; education about schizophrenia; rehabilitation; and managing sexual
17
+ and marital problems of patients.
18
+ Conclusion: This study has identified additional needs of caregivers from those
19
+ found in other studies.

22
+ INTRODUCTION
23
+ The importance of the role of family caregivers in the treatment of a person with mental illness
24
+ cannot be overemphasized. Family caregivers provide considerable support to their ill relatives
25
+ even while they experience significant burden (Leff, 1994). In a survey conducted by Consumer
26
+ Health Sciences (CHS) and the National Mental Health Association (NMHA), one third of the 1,328
27
+ family caregivers surveyed said that the emotional and behavioural symptoms of the illness caused
28
+ them extreme hardship and was a constant source of anxiety (Consumer Health Sciences, 2008).
29
+ Caregivers who are in ‘high contact’ with the patient in their daily life often face the highest burden
30
+ (Winefield & Harvey, 1994). Family coping strategies accounted for a substantial proportion of the
31
+ variance observed in objective and subjective burden respectively among caregivers of persons with
32
+ schizophrenia (Magliano et al., 1998). This highlights the fact that studying the needs of family
33
+ caregivers of patients with severe mental disorders is important from a public health perspective.
34
+ In India, the majority of the people with schizophrenia stay with their families (Thara et al.,
35
+ 1998; Murthy, 2006). There have been no systematic scientific Indian studies to assess the needs
36
+ of caregivers; however, several different opinions have been expressed. Some of the needs opined
37
+ are the need for awareness about the nature and outcome of mental illnesses in the community,

43
+ the need for primary psychiatric and other professional treatment, and psychosocial rehabilitation
44
+ (Goswami, 2006; Janardhan, 2006). Caregivers of inpatients report experiencing a significantly
45
+ higher burden than caregivers of outpatients. Unmet needs of the patients have also been found to
46
+ be significantly related to caregiver burden (Cleary et al., 2005). Meeting these needs would help
47
+ to enhance the level of functioning of the patient (Solomon & Draine, 1994) and to decrease the
48
+ emotional problems of family members (Johnson, 1994).
49
+ Family members of a patient with chronic schizophrenia have multiple needs. The major con-
50
+ cerns and support needs of individuals who assume this stressful role include obtaining support,
51
+ reducing risks to their own well-being, and promoting the well-being of the mentally ill (Chafetz &
52
+
53
+ Barnes, 1989). They often express the need for more support and complain of not having enough
54
+ opportunities to relieve the burden imposed on them (Angermeyer et al., 2000). Educational
55
+ needs include gaining information about early warning signs of the illness and relapse, the effects
56
+ of medication and ways of coping with the patient’s bizarre and assaultive behaviour (Chien &
57
+ Norman, 2003). Often family members living with ill persons are less aware of the psychiatric nature
58
+ of the illness (Padmavathi et al., 1998). Thus it is necessary to understand the needs of families
59
+ of persons with mental illness and to develop specific interventions to meet them in order to help
60
+ reduce caregiver burden (Cleary et al., 2006; Murthy, 2006).
61
+ The present study was conducted in order to assess the needs of the caregivers of schizophrenic
62
+ patients in India. India spends a mere 0.83% of its total health budget on mental health compared
63
+ to England and Wales which spends 13.8% (WHO, 2001); thus, the extent to which the needs of
64
+ caregivers will be met in India is likely to be different. Furthermore, given the differences in the
65
+ socio-cultural milieu, the results of the studies done in other cultures may not be relevant in an
66
+ Indian context.
67
+ Further, studies using scales to assess caregiver needs have the limitation of forcing the re-
68
+ spondents to answer from a list. For instance, studies either focus on specific needs such as edu-
69
+ cational needs (Chien & Norman, 2003) or on groups of needs such as counselling and support
70
+ services, education and financial entitlements (Wancata et al., 2006; Barrowclough et al., 1998). We
71
+ used a qualitative approach to assess the needs of caregivers for several reasons: (a) this approach
72
+ is useful in tapping a broader range of needs that are specific to the context in which it is used;
73
+
74
+ (b) studying the needs of caregivers involves probing of sensitive, emotional and personal themes
75
+ of needs, which is more suited to a qualitative approach (Hiday et al., 2002; Padget, 1998); and
76
+ (c) qualitative studies are especially helpful when one intends to generate impressions and to
77
+
78
+ develop assessment scales, programmes or services (Stewart et al., 2007).
79
+ METHOD
80
+ Sample
81
+ The participants were 30 caregivers of inpatients with schizophrenia at the National Institute
82
+ of Mental Health and Neuro Sciences (NIMHANS) in Bangalore, India – a tertiary care centre.
83
+ NIMHANS has a 900-bed teaching hospital with training and research facilities in psychiatry and
84
+ other neurosciences. In April 2008, caregivers of all inpatients with schizophrenia were screened.
85
+ In total, 59 patients with a diagnosis of schizophrenia were admitted to the hospital during this
86
+ period. Caregivers of patients with a diagnosis of schizophrenia were included in the study if they
87
+ were to continue to provide care for them following discharge and if they spoke Kannada, Tamil,
88
+ English or Hindi. Caregivers with psychiatric or neurological disorders and those caring for another
89
+ 182
90
+ INTERNATIONAL JOURNAL OF SOCIAL PSYCHIATRY 57(2)
91
+ relative with psychiatric illness were excluded. Thirty eight caregivers who fulfilled these inclusion
92
+ and exclusion criteria were approached. Of these 38 caregivers, 30 consented to participate in
93
+ the study. These included families from different socioeconomic backgrounds, different states of
94
+
95
+ India and from different carer roles. The 30 caregivers thus recruited participated in five focus
96
+ group discussions (FGDs), with approximately six caregivers participating in each of the FGDs.
97
+ The sociodemographic data of the caregivers who participated in the FGDs and a profile of their
98
+ ill relatives were compiled (Table 1).
99
+ Focus group discussion
100
+ From the range of qualitative research methods available, the FGD method was selected (vis-à-
101
+ vis individual interviews), as it is less time-consuming, economical and has the benefits of group
102
+ processes (Stewart et al., 2007). The discussions followed the recommendations of Stewart et al.
103
+ (2007) – they involved six to eight individuals who discussed the research question ‘What are the
104
+ needs of family caregivers of inpatients with schizophrenia?’ for approximately 1.5–2.5 hours. The
105
+ FGD was conducted under the direction of a moderator (AJ/HVR) who promoted interactions and
106
+ ensured that the discussions remained focused on the topic of interest.
107
+ Script
108
+ A standardized script for conducting the FGD was developed on the basis of the aims of the
109
+ study, literature review and discussion with four experienced focus group researchers. The script
110
+
111
+ followed a semi-structured format using open-ended questions in a face-to-face ‘conversational’ style
112
+ rather than a formal question/answer format. (The script is available from the authors on request.)
113
+ Although the group discussion script was flexible in nature, some direction was given when the
114
+ focus was lost and probes were used when necessary. The script included discussion about the felt
115
+ needs of the caregivers in caring for their relative with schizophrenia, and the grouping and ranking
116
+ of similar needs according to their order of importance.
117
+ Procedure
118
+ The study was reviewed and approved by the Institute’s ethics committee. Written informed consent
119
+ of the family caregivers was obtained to participate in the study and a sociodemographic sheet
120
+ eliciting information on their age, occupation, monthly income, marital status, patient variables
121
+ and family constellation was completed. Each FGD was video-recorded and was facilitated by
122
+ the researcher (psychiatric social worker) and a co-facilitator. The researcher facilitated the group
123
+ process and the co-facilitator helped in recording the observations of the group session (audio/video
124
+ and by taking down notes).
125
+ The FGD involved the researcher asking the caregivers to list their needs (Appendix), group the
126
+ list of needs into main themes, operationally define the themes and rank them in order of importance.
127
+ As the methodology of free listing of needs was used, all the needs expressed by the caregivers
128
+ were noted. Across all five FGDs, the needs of caregivers were found to be largely comparable.
129
+ Thus, no needs were deleted from the list and all needs were accommodated into either one of the
130
+ categories/themes. In case of differences of opinion within the group about the grouping and ranking
131
+ of similar needs, further discussion and cross-clarification (iteration) was conducted among the
132
+ members who differed in their opinion till a consensus was reached. In groups where consensus
133
+ could not be reached, the themes were given similar ranking (e.g. in FGD-2, the themes of health
134
+ of caregivers, rehabilitation options and managing social/behavioural problems of patients were
135
+ given similar ranking).

292
+ Data analysis
293
+ The first level of data analysis was done during each of the focus group sessions. The researcher
294
+ made a list of needs during the discussion. The group (caregivers) then divided these needs into
295
+ themes and sub-themes and ranked them according to their importance. Following the technique
296
+ of iteration, the group went over these themes and rankings several times before finalizing them. In
297
+ each FGD the most important theme (based on grouping and ranking at level one and two of data
298
+ making) was given the highest score (equal to the number of themes listed) and the least important
299
+ theme was given the a score of 1. If two or more themes were deemed as having equal importance
300
+ during the FGD, then such themes were given similar scores. If a theme was not represented in a
301
+ particular FGD, it was given a score of 0 in that FGD.
302
+ Each FGD was transcribed and further data making and analysis was conducted by the researcher
303
+ (second level of data making). Based on the first level of data making, the researcher reviewed
304
+ the listing of themes and wherever two or three themes seemed to represent a common theme,
305
+ they were grouped under an appropriate theme. The theme thus generated was given a score by
306
+ averaging the scores from the first level of data making. For example, in FGD-5, out of the six
307
+ themes identified by the caregivers, themes of ‘educational needs’ (score = 6) and ‘information on
308
+ management of side effects of medicines’ (score = 4) were grouped by the researcher as one main
309
+ theme of ‘education needs’ and given a score of 5.
310
+ The researcher then checked the remaining text for leftover lists of needs and put them under the
311
+ most appropriate theme. The scores for each theme across the five FGDs were totalled. The final
312
+ ranking of the themes corresponded to these totals; the theme with highest total score was ranked
313
+ as the most important need (Table 2).
314
+ The needs under each theme across the five FGDs were listed. A final list of themes and needs
315
+ under each theme was tabulated for analysis. As the sample size in each FGD was small, no
316
+ computer-assisted software package was used for the data analysis. Computer software would have
317
+ been appropriate if 30 individual interviews had been conducted instead of six groups.
318
+ During the entire study period, the ill relative continued to receive the routine treatment prescribed
319
+ by the doctors at NIMHANS. The treating doctors were consulted and their approval to conduct
320
+ the FGD was obtained.
321
+ RESULTS
322
+ The main needs that emerged from the analysis of the FGDs are described in Table 2.
323
+ I: Managing illness behaviour
324
+ The areas in which the caregivers needed help to manage the illness behaviour of their relative
325
+ were: managing their non-compliance with medication; uncooperative behaviour; aggressive and
326
+ demanding behaviour; dealing with their illness symptoms (hallucinations/delusions, wandering,
327
+ insomnia, spending behaviour, reduced food intake); increased substance use; handling their
328
+ unpredictable behaviour; lack of interest in self-care; concentration problems; and lack of daily
329
+ routine. The following quotes of the caregivers depict the problems they faced in managing the
330
+ illness behaviour of their relative.
331
+ ‘Even when the family members advise or request, my brother says, “No I am not the patient;
332
+ you have a problem, so why should I take the medication?”’ (Mr S.M. (47 years), FGD-2)

+ she suspects that I have mixed poison or faeces in the food.’ (Mrs J. (36 years), FGD-3)
339
+ ‘Suddenly my daughter gets angry, very angry to an extent that she does not get pacified until
340
+ and unless she hurts someone, even if it were my son or myself.’ (Mrs J. (36 years), FGD-3)
341
+ ‘My daughter does not do anything. I have to do everything for her… from combing her hair,
342
+ washing her clothes. I have to scrub and bathe her also.’ (Mrs J. (36 years), FGD-3)
343
+ II: Managing social-vocational problems
344
+ Caregivers discussed various areas where they needed professional help in managing the social-
345
+ vocational problems of their ill relative. These were: dealing with patient’s lack of interest in
346
+ socialization/not going out of the house; relationship problems; uninhibited behaviour; and difficulty
347
+ in initiating and maintaining activities/job. The following quotes of the caregivers throw light on
348
+ the social-vocational problems.
349
+ ‘My son is always in the home. He never goes out. He does not mix even with our relatives or
350
+ workers… he finds it difficult to get out of the room.’ (Mrs B.M. (60 years), FGD-2)
351
+ ‘My son comes out of the bathroom at times without wearing his clothes. Even when we tell him,
352
+ he does not listen. It becomes very difficult if there are guests at home.’ (Mr M.S. (45 years),
353
+
354
+ FGD-3)
355
+ ‘I would want my son to go to a job. He has forgotten about going for the job completely. He
356
+ does not have a mind to go for a job. (Mr M.R. (65 years), FGD-4)
357
+ My son has changed seven companies. In no company he has worked for more than two to three
358
+ days… He gets a job easily. Four appointments are in hand. But after joining, he cannot maintain
359
+ the job.’ (Mr R. (68 years), FGD-4)

432
+ III: Health needs of caregivers
433
+ Caregivers had a number of health needs. They required help in: managing their emotions (anger,
434
+ depression, fear); handling their stress; taking decisions; dealing with lack of social support;
435
+ reduced personal life; and balancing work and patient care. The following quotes of the caregivers
436
+ exemplify their health needs.
437
+ ‘I am always worried about the possibility of such events happening at home [violent outburst of
438
+ the patient]. So we continuously suffer from tension and sadness.’ (Mr M.S. (45 years), FGD-3)
439
+ ‘No facility, no neighbours, no relatives or friends came to help us when the patient was violent.
440
+ We were helpless and did not know what to do. [Mr C.R. is overwhelmed and starts crying.] Even
441
+ if I called for the ambulance at our place, they do not come. Thus we start getting negative feelings
442
+ like anger. We need to know how to control these feelings.’ (Mr C.R. (25 years), FGD-2)
443
+ ‘For the past 10 years [since my brother’s illness started], the concept of my personal life is
444
+ completely zero. I am now adjusted to this life and I stopped my studies. I now take care of my
445
+ brother full-time as my parents are aged.’ (Mr S. (33 years), FGD-4)
446
+ IV: Education
447
+ Education needs of the caregivers included: education about the illness; information on medication/
448
+ side effects/emergency medicine (sedatives); information on available concessions/benefits offered
449
+ by the government; and information on how to deal with stigma. The following quotes depict the
450
+ caregiver needs for education.
451
+ ‘The medicines have so many side effects. The doctor does not tell us that this medicine will
452
+ give side effects.’ (Mr I.K. (60 years), FGD-1)
453
+ ‘In event of the patient becoming very violent and not responding to us, if there is any pill
454
+ which can be given to him at that time and if he sleeps… [another group member continues]…
455
+ one liquid… if by adding a few drops in food, he will be ok, we can then bring him to the
456
+ hospital. But we don’t know what to give and what not to give [pill]. We need education on that.’
457
+
458
+ (Mr S.M. (47 years) and Mrs B.M. (60 years), FGD-2)
459
+ ‘For the patient and caregivers we should know about the concessions available from the gov-
460
+ ernment. For other people [of other disorders] they get reimbursed for their treatment. We are
461
+ not getting any money from anywhere and we have to spend a lot of money.’ (Mrs B.M. (60
462
+ years), FGD-2)
463
+ ‘There is a lot of stigma about this illness… a lot of misconceptions about mentally ill patients.
464
+ They do not understand what type of illness this is, what is the problem. So educating society is
465
+ important.’ (Mr C.R. (25 years), FGD-2)
466
+ V: Rehabilitation
467
+ All caregivers cited these rehabilitation needs: knowing about financial and rehabilitation options;
468
+ local support groups and helpline services; office/work benefits for caregivers; and local referral
469
+ systems. The following quotes depict the rehabilitation needs of the caregivers.
470
+
471
+ JAGANNATHAN ET AL.: A QUALITATIVE STUDY ON THE NEEDS OF CAREGIVERS
472
+ 187
473
+ ‘Psychiatric patients have very few rehabilitation options… patients who are well… around 70%
474
+ of them, if some small jobs can be provided for them… small encouragement can be given to
475
+ them by the government, it would be helpful.’ (Mr I.K. (60 years), FGD-1)
476
+ ‘Development of local support groups in city/hometowns like palliative care groups for cancer
477
+ patients will be a great relief to all people, wherever we are.’ (Mrs M. (52 years), FGD-2)
478
+ ‘At least in medical colleges, connected with this issue a helpline can be opened. The government
479
+ can do this.’ (Mrs B.M. (60 years), FGD-2)
480
+ ‘If we are government employees, at any time, we do not get leave and we can get transferred.
481
+ Even when I tried to convince my superiors that I had to take care of three mentally ill persons
482
+ at home [officers] they did not listen. They processed my transfer order. So if certain rules
483
+
484
+ and regulations to give leave to us as a caregiver of a patient are made, it would be useful.’
485
+
486
+ (Mr C.R. (25 years), FGD-2)
487
+ ‘A small centre should be made available [developed] in our state, in any of the cities or in any
488
+ place in the state – with one doctor. If patient does not want to come to NIMAHNS, we do not
489
+ know where to take him. In every crisis situation we cannot come over here [to NIMHANS].
490
+ There needs to be a local referral system.’ (Mrs B.M. (60 years), FGD-2)
491
+ VI: Managing the sexual and marital problems of patients
492
+ Caregivers of persons with mental illness faced a number of problems related to the sexual and
493
+ marital issues of the patient. They needed help in dealing with issues such as: whether to get the
494
+ patient married; problems in getting patient married; problems in maintaining the patient’s marriage
495
+ post-illness (separation/divorce issues); and problems of the patient related to sexual activities/
496
+ marital discord. The following quotes of caregivers exemplify some of the above themes.
497
+ ‘We have seen a few girls for my son’s marriage. But all the parties we go to see, somebody in
498
+ our village would have already told them that he is not mentally well and the alliance would be
499
+ rejected.’ (Mrs B.M. (60 years), FGD-2)
500
+ ‘My brother is married but his wife does not stay with him. He has a child and his wife has put
501
+ the child in a hostel. This is because from 1999 he is getting treatment from NIMHANS and he
502
+ was not cured. After he goes back home, within a few days the symptoms relapse. So his wife’s
503
+ father and mother have advised her not to go back to her husband. We do not know how to deal
504
+ with this situation.’ (Mr S.M. (47 years), FGD-2)
505
+ DISCUSSION
506
+ The needs of the caregivers are extensive and vary across cultures. An in-depth assessment and
507
+ analysis is of paramount importance in order to develop programmes to cater to the needs of
508
+ caregivers in a cultural context. The present study explored the needs of caregivers of inpatients
509
+ with schizophrenia in India. The three main needs that emerged from the analysis of the FGDs,
510
+ 188
511
+ INTERNATIONAL JOURNAL OF SOCIAL PSYCHIATRY 57(2)
512
+ were (in order of importance) help in: (1) managing the illness behaviour of the patients;
513
+
514
+ (2) managing social-vocational problems of patients; and (3) health needs of the caregivers.
515
+ Some published studies have focused on specific needs such as rehabilitation and/or education
516
+
517
+ (Chien & Norman, 2003; Winefield & Harvey, 1994). Most other studies have used a standardized
518
+ needs questionnaire to assess caregiver needs. The Camberwell Assessment of Need (CAN), one
519
+ of the most widely used, is more often used with persons who are in contact with mental health
520
+ services and are receiving inpatient, outpatient or day-patient care (Phelan et al., 1995). The Carer’s
521
+ Needs Assessment (CNA) and the Relatives Cardinal Needs Assessment (RCNS), on the other
522
+ hand, focus on caregivers’ educational, financial, social and interpersonal, professional support
523
+ and health needs (Wancata et al., 2006; Barrowclough et al., 1998).
524
+ Assessing the needs through the method of a questionnaire could limit the range of expression
525
+ of the needs of caregivers. The qualitative assessment method used in this study has been useful
526
+ in finding in-depth requirements of caregivers in each need area – an additional comprehensive
527
+ result, different from that of other studies. For example, under ‘health needs’ various caregivers’
528
+ requirements were covered such as the need to manage stress and emotions, the need to maintain
529
+ balance between caregiving and personal life/work and the need to know how to take decisions in
530
+ stressful situations.
531
+ The results of the current study could also be interpreted in terms of the sample – how needs of
532
+ caregivers of inpatients (who had recently become ill or whose illness had exacerbated) could differ
533
+ from those of caregivers of outpatients (Cleary et al., 2006). The caregivers who participated in
534
+ this study were more patient-focused rather than carer-focused. This reflects not just the altruistic
535
+ preoccupations of focus group participants, but also the fact that all these caregivers were taking
536
+ care of patients who were currently symptomatic and required immediate hospitalization for their
537
+ symptom control. Managing the symptoms of the patients was always considered as the most
538
+ important priority. There were differences in opinion between caregivers in some groups about
539
+ whether rehabilitation, education or their health needs was the next important need. The homogeneity
540
+ of the sample (all caregivers of inpatients with schizophrenia) could be a reason for all the caregivers
541
+ having similar priorities in taking care of their patient.
542
+ Further cultural factors, such as strong family systems, could have a bearing on the results of
543
+ the study. In India the patient is always accompanied by the family member (who is the caregiver)
544
+ as compared to other countries where caregivers are not necessarily family members (Thara et al.,
545
+ 1998; Leff, 1994).
546
+ The sociodemographic profile of the caregivers in this study is consistent with that of earlier
547
+ studies on Indian caregivers of persons with schizophrenia (Srinivasan, 2006; Murthy, 2007). All
548
+ caregivers were family members. Most of them were parents, especially mothers who had a lower
549
+ income and were into late adulthood or old age. It may also be noted that the proportion of patients
550
+ living in nuclear families in this study (76.7%) is comparable to that of the general population of
551
+ India (70.4%; Office of the Registrar General and Census Commissioner, India, 2001).
552
+ Caregivers in the study reported that their primary need was help in managing the symptoms of
553
+ the patient. Due to lack of knowledge, fear and stigma associated with mental illness, caregivers
554
+ often found themselves at a loss as to how to do this (Gandon et al., 2008). Dealing with the social-
555
+ vocational problems of the patient (second need), was another area of concern for the caregivers.
556
+ Some expressed more concern about ‘negative’ symptoms of schizophrenia (e.g. social withdrawal)
557
+
558
+ JAGANNATHAN ET AL.: A QUALITATIVE STUDY ON THE NEEDS OF CAREGIVERS
559
+ 189
560
+ than about positive ones (e.g. hallucinations) (North et al., 1998). Further caregivers seemed to
561
+ understand that they had to take care of their own health (third need) in order to better care for
562
+ the patient.
563
+ Apart from the above three main needs, caregivers also perceived the need for education (fourth
564
+ need) as important, as it would help reduce stigma in society about mental illness (Murthy, 2006).
565
+ Caregivers required information not only about the illness, but also about medication/side effects/
566
+ emergency medication (sedatives) and about the available concessions/benefits offered by the
567
+ government (Cleary et al., 2005; Chien & Norman, 2003). The concept of stigma was discussed
568
+ by the caregivers who participated in FGD-2 in the context of ‘educating the society to minimize
569
+ the stigma in society’. Thus, the issue was considered under the category of education as the focus
570
+ was on educating society – clearing misconceptions, not eradicating stigma. Rehabilitation (fifth
571
+ need) was expressed as important by the caregivers; as most of the caregivers stayed in nuclear
572
+ families, they required help in the form of financial and legal concessions, office/work-related
573
+ benefits for caregivers, rehabilitation centres/day care near home, helpline services and local support
574
+ groups. Apart from the availability of these services, they also needed information about them and
575
+ help in accessing these services (Cleary et al., 2005). The sixth need was sexual and marital prob-
576
+ lems and knowing how to deal with them. This was a significant need in the Indian context as
577
+ marriage and procreation are considered to be important stages in the Indian family life cycle
578
+ (Madan, 1987). Caregivers wanted to know whether to get their patient married; the stigma of
579
+ getting the patient married with a mental illness; and how to deal with difficulties post-marriage
580
+ like relapse of symptoms and marital discord.
581
+ In a country where there are very few psychiatrists, the focus of treatment is more on symptom
582
+ cure. Even in a tertiary multidisciplinary centre like NIMHANS, the focus is often on needs other
583
+ than the health needs of the caregivers. Estimates show that 50% of patients approach NIMHANS
584
+ as a primary care centre (Kare et al., 2008). This makes it difficult to deal with all the needs of the
585
+ patients and caregivers. Needs like rehabilitation, education and sexual concerns of the patient can
586
+ be managed at hospital level. However, the health needs of caregivers that are equally important
587
+ are often not taken as part of the patients’ treatment process at the hospital. As its aim, this study
588
+ will attempt to develop a structured intervention programme based on the holistic coverage of all
589
+ the needs of the family caregivers.
590
+ Certain methodological issues of this study need to be mentioned. The method of FGD has certain
591
+ inherent limitations such as the group members’ responses are not independent of one another,
592
+ which restricts the generalizability of the results (Stewart et al., 2007). Some of the members were
593
+ hesitant to talk in a group situation – especially when sharing sensitive issues. Caregivers may
594
+ have expressed other needs if they had been interviewed individually. Individual interviews could
595
+ thus have added considerable strength to the results of the study. Any interpretation of the results
596
+ needs to be done keeping in mind the exclusion of carers who were not comfortable with a group
597
+ situation. Further, the results obtained from the FGD may have been biased by a very dominant
598
+ or opinionated member. Future studies could examine the validity of the hierarchy of needs by
599
+ presenting the findings of this study to another focus group of carers.
600
+ To counter some of these methodological limitations, informed consent of the members to
601
+ participate in a focus group was taken before the start of the FGD. Those members who were not
602
+ comfortable with talking in a group situation were not chosen for the study. Further, the moderator
603
+ bias was minimized by asking the group members themselves to list and rank the needs without
604
+ consulting the moderator.
605
+ 190
606
+ INTERNATIONAL JOURNAL OF SOCIAL PSYCHIATRY 57(2)
607
+ All family caregivers who attended the FGDs emphatically stated that they required help
608
+ in managing all their needs and expressed their willingness to participate in any training that
609
+
610
+ addressed this.
611
+ CONCLUSIONS
612
+ This study is one of the first scientifically researched qualitative needs assessment studies of the
613
+ caregivers of inpatients with schizophrenia in India. Further, this study gives an holistic view of
614
+ the needs of caregivers with the list of themes and sub-themes that need to be considered for any
615
+ future action. It puts significant emphasis on health needs of the caregivers (third important theme),
616
+ which has often been ignored in other interventions. It must be noted that each patient may have
617
+ more than one caregiver and help of any kind to manage their health needs may have public health
618
+ significance.
619
+ Finally, these findings are highly indicative and future studies could test the results in a larger
620
+ quantitative sample to reconfirm the validity, reliability and generalizability of the results. If validated,
621
+ it would enable the development of any programme developed for Indian family caregivers based on
622
+ the needs assessment. As an outcome of this study, the researchers plan to develop a psychosocial
623
+ and yoga programme for family caregivers of inpatients with schizophrenia in India.

+ Background and objective: The practice of yoga is associated with
13
+ enhanced psychological wellbeing. The current study assessed the
14
+ correlation between the duration of yoga practice with state mindful-
15
+ ness, mind-wandering and state anxiety. Also, we examined if an
16
+ additional 20 min of yoga breathing with intermittent breath holding
17
+ (experimental group) for 8 weeks would affect these psychological
18
+ variables more than regular yoga practice (control group) alone.

26
+ State mindfulness attention awareness scale (SMAAS), Mind-

29
+ Results: Baseline assessment revealed a positive correlation
30
+ between duration of yoga practice with SMAAS scores and nega-
31
+ tive correlation with MWQ and state anxiety scores. At the end
32
+ of 8 weeks, both groups demonstrated enhanced psychological
33
+ functions, but the experimental group receiving additional yoga
34
+ breathing performed better than the group practicing yoga alone.
35
+ Conclusion: An additional practice of yoga breathing with
36
+ intermittent breath holding was found to enhance the psycho-
37
+ logical functions in young adult yoga practitioners.

42
+ Mind-body interventions are found to be useful to managing
43
+ stress.4 Yoga, a noted mind-body intervention has been found
44
+ useful to manage stress and enhance performance.21,22 Among
45
+ various dimensions of yoga practices, Pranayama is an important
46
+ aspect wherein voluntary regulation of the breathing is per-
47
+ formed, while paying mindful attention.23 There are various
48
+ yoga breathing techniques described in the yoga scriptures with
49
+ their potential benefits.17 The regulation of breathing prescribed
50
+ in yoga includes breathing at different pace, alteration of nostrils
51
+ or retention of breath. Earlier reports reveal positive impact of
52
+ mindful breathing on emotional status, through reduction of
53
+ negative affect and emotional volatility.1 There was a reduction
54
+ in perceived stress noted following training in yoga breathing.2,19
55
+ There was also a reduction in test anxiety and improved test per-
56
+ formance following training in Pranayama.18 However, not
57
+ much is known about the impact of yoga and specific yoga
58
+ breathing practices on mindfulness and mind-wandering.
59
+ Mindfulness and Mind-Wandering are two opposing con-
60
+ structs of human psychology.16 Mindfulness is defined by
61
+ Kabat-Zinn as “the awareness that emerges through paying
62
+ attention on purpose, in the present moment, and non-judgmen-
63
+ tally to the unfolding of experience moment by moment”.7
64
+ Recently, mindfulness has been identified as a behavioral para-
65
+ digm that aims at enhancing awareness of the experience at the
66
+ given time, of perceptible mental processes. It is also considered
67
+ as an important aspect of the practice of meditation. Earlier stud-
68
+ ies show mindfulness as an attribute which correlates negatively
69
+ with mind-wandering as well as anxiety.15 Training in mindful-
70
+ ness has been found to reduce mind-wandering and enhance per-
71
+ formance in cognitive tasks involving working memory.14 Such
72
+ training involved practice of attention on breathing and body. A
73
+ recent study shows the brief practice of mindfulness-based inter-
74
+ vention helped children increase the state mindfulness.9 Initial
75
+ reports also suggest a positive role of mindfulness in learning
76
+ and intelligence.5
77
+ Mind-wandering is described as interruption of task-focus by
78
+ task-unrelated thoughts.29 Mind-wandering is a common phe-
79
+ nomenon and is often a sign of unpleasant emotions,8 negative
80
+ mood,27 depression,28 adult Attention Deficit Hyperactivity Dis-
81
+ order12,25 and declined task engagement.20 There is also evidence
82
+ to determine role of anxiety in increased episodes of mind-wan-
83
+ dering through stereotypical threats.13 Due to impairment of
84
+ encoding of information, mind-wandering could lead to failures
85
+ in building a propositional model of a sentence. Thereby, it
86
+ could affect learning abilities by impairing the construction of a
87
+ narrative model having sufficient details to allow generating
88
+ inferences.26 The studies with neuroimaging have demonstrated

107

+ TAGEDH1MATERIALS AND METHODSTAGEDEND
115
+ Subjects
116
+ 143 healthy volunteers studying various long-term residential yoga courses
117
+ at Swami Vivekananda Yoga Anusandhana Samthana (a yoga university),
118
+ Bengaluru, India, were briefed about the study protocol, out of which 130
119
+ consented to participate in the study. The volunteers were screened for
120
+ any major illnesses by a physician who otherwise had no role in the study.
121
+ We excluded participants with a history of respiratory and psychological
122
+ illnesses, use of any medications that could modify mood or cognition.
123
+ We also excluded volunteers who had a history of consumption of alco-
124
+ hol, tobacco or any other habit-forming drugs in any form. Finally, 116
125
+ subjects (44 male + 72 female) were recruited for the study and were ran-
126
+ domly assigned into the experimental group (n = 60) and control group
127
+ (n = 56). The random allocation of the subjects was carried out using ran-
128
+ dom numbers generated using a web-based computer program (www.ran
129
+ domizer.org). The trial profile is illustrated in Fig. 1. The demographic
130
+ data of the subjects is presented in Table 2.
131
+ Ethical Considerations
132
+ The study was approved by the Institutional Ethics Committee of the
133
+ University. Written informed consent forms were obtained from individ-
134
+ ual participants prior to their recruitment to the study.
135
+ Intervention
136
+ Experimental Group: The study was carried out over a period of eight
137
+ weeks. After obtaining the baseline data, the experimental group was
138
+ trained in the Yoga based breathing intervention in addition to routine
139
+ yoga practice of 1 hour/day. The intervention included training for eight
140
+ weeks in the regulated yoga breathing for 20 min incorporating phases of
141
+ inhalation (puraka), internal retention of breath (antarkumbhaka), exhala-
142
+ tion (recaka) and external retention of breath (bahyakumbhaka) in a ratio
143
+ of 1:1:1:1 for 6 s each. The classic yoga texts suggest breath retention in
144
+ varying ratios. We chose this ratio for the intervention since it is consid-
145
+ ered ideal for subjects who are na€
146
+ ıve to the practice of breath holding.
147
+ The intervention was derived from a classical training methodology of
148
+ pranayama suggested in the ancient text of Yoga.23 The duration of 6 s
149
+ was decided based on a previous study which used the similar interval of
150
+ phases of breath hold.30 The duration of 6 s was ensured through verbal
151
+ cues in a pre-recorded audio track.
152
+ Control Group: The control group underwent yoga practices for 1 hour
153
+ practice of Yoga/day for 6 days a week, same as the experimental group.
154
+ The routine yoga practices are listed in Table 1.
155
+ Assessments
156
+ We used three self-report questionnaires viz. Mind-Wandering Question-
157

+ TAGEDH1DISCUSSIONTAGEDEND
312
+ The current study evaluated correlations of state mindfulness,
313
+ Mind-wandering and state anxiety with the duration of yoga experi-
314
+ ence as well as each other. The observations confirmed the initial
315
+ hypothesis, that state mindfulness will be positively correlated to
316
+ duration of yoga experience and negatively to state anxiety and
317
+ Mind-wandering. The study also assessed if an additional practice
318
+ of yoga breathing with intermittent breath holding (experimental
319
+ group) could influence the psychological constructs more than per-
320
+ forming regular yoga practices for one hour/day, 6 days/week alone
321
+ (control group). The findings suggest that regular practice of yoga
322
+ helps to reduce state anxiety and Mind-wandering, whereas an addi-
323
+ tional practice of yoga breathing with intermittent breath holding
324
+ enhances state mindfulness while also reducing the Mind-wander-
325
+ ing and state anxiety. The between group analyses indicate that
326
+ additional yoga breathing with intermittent breath holding could
327
+ lead to better psychological framework than performing regular
328
+ yoga practice alone.
329
+ The scores of the 3 questionnaires at baseline indicate the
330
+ positive influence of yoga practice on psychological state of
331
+ the individuals. The mean score of state anxiety for the study
332
+ population (N = 112) at the baseline (33.52) was slightly
333
+ lower than ‘normal’ score described for the same (3436).10
334
+ The state anxiety score was found to be negatively correlated
335
+ to the years of yoga experience. Although there is lack of
336

338
+ for
339

340

413
+ Yoga Breathing Enhance Psychological Wellbeing
414
+ Our findings concur with earlier studies proposing increased
415
+ mindfulness in yoga practitioners31 along with lowered anxiety.32
416
+ There have been no earlier studies eliciting the effects of yoga inter-
417
+ ventions on Mind-wandering as a psychological construct. Yet,
418
+ mindfulness and mind-wandering are known to have negative corre-
419
+ lation.14 Our results are consistent with an earlier study which used
420
+ an attention task, mindfulness and mind-wandering as the outcome
421
+ measures. The findings suggested mindful breathing enhanced the
422
+ performance in the attention task, mindfulness and reduced mind-
423
+ wandering.16 Mindful breathing was proposed to help in reducing
424
+ the thought-unrelated thoughts and improve metacognitive regula-
425
+ tion by increasing awareness of mind-wandering. In our study, we
426
+ used yoga breathing with intermittent breath holding, which needed
427
+ focused attention for synchronization of the breathing with the audi-
428
+ ble cues, thus possibly not allowing the mind-wandering to occur.
429
+ And over time, practice may have led to enhanced mindful state and
430
+ reduced mind-wandering. Mrazek et al. also observed association of
431
+ negative mood with mind-wandering.16 Another study correlates
432
+ negative state of mind leading to mind-wandering.8 Our study
433
+ observed a reduction in anxiety, which may also be contributing to
434
+ elevated mood and thus reduced mind-wandering and enhanced
435
+ mindfulness. Another possible mechanism of action for the observed
436
+ effects could be diminished activity of the default mode network in
437
+ cortical regions that is associated with Mind-wandering. A recent
438
+ study demonstrated such diminished activity of default mode net-
439
+ work following focusing on internal or external objects mindfully.24
440
+ An earlier study on mindful breathing performed on undergrad-
441
+ uate students who were na€
442
+ ıve to the intervention demonstrated
443
+ significantly reduced negative affect following the intervention.1
444
+ The study observed that the subjects were able to approach the
445
+ stimuli in a mindful manner following the breathing intervention,
446
+ signifying better emotional regulation. The subjects in our study
447
+ were yoga practitioners and thus may have better emotion regula-
448
+ tion. Further clinical trials may include the measures of emotion
449
+ regulation for understanding the underlying mechanisms.
450
+ The control group continued to attend the regular yoga sessions
451
+ with an additional 20 min of sports activities/day. There was sig-
452
+ nificant reduction in state anxiety as well as mind-wandering in
453
+ the control group, which may be attributed to anxiolytic effects of
454
+ yoga.32 Yet, the changes observed in the constructs were signifi-
455
+ cantly higher in the experimental group, which performed an
456
+ additional yoga breathing intervention, thus demonstrating the
457
+ beneficial effects of the add on yoga breathing.
458
+ The limitations of the current study include use of self-report
459
+ measures alone. Further trials could estimate if the enhanced
460
+ mindfulness and reduced mind-wandering could affect the per-
461
+ formance of the study population in attention related tasks.
462
+ Also, we lacked an actual control group, since both the groups
463
+ were yoga practitioners and continued to perform regular yoga
464
+ sessions. Further trials may include a non-yoga practitioner
465
+ group for better generalization of the observed results.
466
+ TAGEDH1CONCLUSIONSTAGEDEND
467
+ The findings of the current study are suggestive of a dose-effect
468
+ relationship of duration of yoga enhancing mindfulness and
469
+ reducing mind-wandering and anxiety. The results also indicate
470
+ a negative correlation between mindfulness and mind-wandering
471
+ as well as anxiety. We also observed that an additional practice
472
+ of yoga breathing with intermittent breath holding for 20 min
473
+ has a better influence on the psychological constructs when com-
474
+ pared with regular yoga practice alone. Further trials are war-
475
+ ranted to understand the mechanisms of the observed effects.

+ Abstract
12
+ This study examined the relationship between aerobic fitness and cognitive functions in 7-9 year old
13
+ school going children hailing from a socio-economically disadvantaged background in Bangalore, India.
14
+ Ninety eight children (51% boys and 49% girls) were assessed on height, weight, BMI, aerobic fitness (multi-
15
+ stage 20 m shuttle test) and cognitive functions (verbal tests: comprehension, arithmetic, vocabulary, analo-
16
+ gies; performance tests: block design, object assembly and coding). Number of shuttles wassignificantly
17
+ positively correlated with two of the cognitive tests: comprehension (p=0.01) and block design (p=0.005).
18
+ Multiple linear regression analysis showed that the number of shuttles emerged as an independent predictor
19
+ of tests of comprehension and block design after adjusting for BMI and gender. The above findings provide
20
+ preliminary evidence for the association between aerobic fitness and cognitive functions in children from
21
+ poor socio-economic background.

+ INTRODUCTION
33
+ A recent meta-analysis on school based physical activ-
34
+ ity and cognitionshowedthat physical activity had a posi-
35
+ tive influence on concentration, memory and classroom
36
+ behavior (1). Experimental studies using either a cross sec-
37
+ tional design or test-post test comparison demonstrated a
38
+ significant positive relationship between physical activity
39
+ and cognitive performance in children (2). A recent review
40
+ examining the effects of aerobic exercise on various cog-
41
+ nitive tasks found that the optimal intensity for impacting
42
+ cognitive tasks covered a wide range (~40–80% VO2max)
43
+ and exercise duration of more than 20 minutes was most
44
+ efficient in increasing the performance on perceptual and
45
+ decisional tasks (3). However, a meta-regression analysis
46
+ concluded that the empirical literature did not support a
47
+ link between cardiovascular physical fitness and cogni-
48
+ tive performance (4), but the number of studies that had
49
+ young children as subjects was very small. In the last two
50
+ decades there has been a resurgence of interest in the area
51
+ of physical fitness, cognitive and academic performance
52
+ in children and adolescents. In a recent randomized con-
53
+ trolled trial of aerobic exercise training on cognition in
54
+ overweight children, there was a significant improvement
55
+ in executive functions in children in the high dose exer-

59
+ cise group compared to controls (5). Most of the published
60
+ studies on physical exercise and cognition in children have
61
+ come from the West with few published studies from de-
62
+ veloping countries. To the best of our knowledge there are
63
+ no known published Indian studies examining physical ac-
64
+ tivity and cognition in school children from an economi-
65
+ cally disadvantaged background. In the present study, we
66
+ examined the association between aerobic fitness and cog-
67
+ nitive functions in 7-9 year old school going children from
68
+ a socio-economically disadvantaged background living in
69
+ Bangalore, India.
70
+ METHODS
71
+ The sample size consisted of hundred, 7-9 year old
72
+ healthy (as assessed by clinical examination by medical
73
+ professionals) school going children hailing from a socio-
74
+ economically disadvantaged background (average monthly
75
+ income of 2000 INR, equivalent to 46 USD approximate-
76
+ ly). All participants were recruited from a single school in
77
+ Urban Bangalore, India. From a total of 200 children who
78
+ were part of a larger interventional study on the effects of
79
+ yogapractices on cognitive performance, physical fitness
80
+ was assessed in 100 randomly selected children at baseline
81
+ before the start of yoga intervention. The children gave oral
82
+ assent while the parents/legal guardian provided written
83
+ informed consent. The school also provided written per-
84
+ mission to conduct the study on its children, on the school
85
+ premises. The study was approved by the Institutional Ethi-
86
+ cal Review Board of St. John’s National Academy of Health
87
+ Sciences. Socio-demographic details were obtained from all
88
+ children. Height, weight and BMI (Body Mass Index) were
89
+ recorded. Children underwent a physical examination and
90
+ apparently healthy children with no history of chronic dis-
91
+ eases, physical or mental handicap and not severely under-
92
+ nourished (<-3SD for weight for age and -3SD height for age
93
+ z scores of the National center for health statistics / WHO
94
+ standards) (6) were invited to participate in the study. The
95
+ Indian adaptation of WISC II, Malin’s Intelligence Scale for
96
+ Indian Children (7) was used to measure cognitive perfor-
97
+ mance. The test contains both verbal and performance sub-
98
+ tests. For the purpose of the present study, 4 verbal, and 3
99
+ performance tests from the battery of tests were used. The
100
+ verbal tests were comprehension, arithmetic, vocabulary
101
+ and analogies. Block design, object assembly and coding
102
+ were the performance tasks. The tests were administered by
103
+ trained psychologists in the morning hours.
104
+ The multistage 20 m shuttle test described by Leger
105
+ and Lambert (8) was used as an index of physical fitness.
106
+ The children were required to run continuously between
107
+ two points which were 20 m apart. The pace of run-
108
+ ning was indicated by an audio recording which emitted
109
+ beeps at prescribed intervals. The initial speed was set at
110
+ 4 km/h and increased by 0.5 km/h for each subsequent
111
+ minute. The test was discontinued when the child vol-
112
+ untarily stopped due to fatigue. The total number of laps
113
+ completed was used as an index of physical fitness. Pre-
114
+ vious research has shown that the number of laps com-
115
+ pleted positively correlates with VO2 max (9). All study
116
+ assessments were conducted in the school premises. At
117
+ the time of conducting test of aerobic fitness all children,
118
+ as part of the school curriculum, were doing physical ex-
119
+ ercises such as running and stretching exercises for about
120
+ 30 minutes twice a week.
121
+ Statistical Analysis
122
+ Analyses were done using the SPSS (version 17) soft-
123
+ ware. Continuous variables were reported using mean
124
+ (SD) and the categorical variables were reported using fre-
125
+ quencies and percentages. Non normal data was log trans-
126
+ formed. Pearson correlation coefficient was computed to
127
+ assess the association between the cognitive measures and
128
+ the number of shuttles. Multiple linear regression analysis
129
+ was computed to identify the predictors of cognitive mea-
130
+ sures. In the regression analysis BMI and sex were adjust-
131
+ ed for since these factors have been reported to influence
132
+ aerobic functioning. All analysis was considered statisti-
133
+ cally significant at the 0.05 level of significance.
134
+ RESULTS
135
+ Of the 100 children enrolled in the study, 98 children
136
+ completed both the assessments (physical fitness and cog-
137
+ nitive tests); both genders were almost equally distributed
138
+ (boys=51%). The children hailed from the lower socio-
139
+ economic strata with average parental income ofRs, 2000
140
+ per month (US $46). Most of the parents were employed
141
+ as daily wage laborers and were illiterate. The mean age of
142
+ the sample was 7.9 ± 0.9 yrs. The mean height, weight and
143
+ BMI of the sample were 1.21 ± 0.07 m, 20.4 ± 3.06 Kg and
144
+ 13.8 ± 1.1 respectively.
145
+ For the analysis the number of shuttles was used as
146
+ the indicator of physical fitness. The average number of
147
+ shuttles completed was 46.1 ± 14.2. In the verbal tests of
148
+ comprehension, arithmetic, analogies and vocabulary the
149
+ mean scores were 7 ± 2.4, 5.2 ± 1.9, 6.2 ± 3.2 and 13.1 ±
150
+ 4.4 respectively. The mean scores for the various perfor-
151
+ mance tests that included block design, object assembly
152
+ Aerobic fitness and cognitive functions in Indian children
153
+ 102
154
+ and coding were as follows: 6.2 ± 4.1, 4.5 ± 2.5, and 32.4
155
+ ± 8.1 (Table 1).
156
+ The number of shuttles wassignificantly positively
157
+ correlated with two of the cognitive tests: comprehen-
158
+ sion (P=0.01) and block design (P=0.005) (Table 2). Mul-
159
+ tiple linear regression analysis showed that the number of
160
+ shuttles is an independent predictor of tests of comprehen-
161
+ sion and block design after adjusting for BMI and gender.
162
+ Results indicated that number of shuttles explained 8% of
163
+ the variance in comprehension and block design scores re-
164
+ spectively (Table 3).
165
+ DISCUSSION
166
+ The main objective of the study was to explore the as-
167
+ sociation between aerobic fitness and cognitive functions
168
+ in 7-9 year old children from a poor socio-economic back-
169
+ ground. The study findings indicated a positive associa-
170
+ tion between aerobic capacity as measured by shuttle tests
171
+ and cognitive functions in 7-9 year old children. This is
172
+ corroborated by previous research where children who are
173
+ physically fit perform better and faster on cognitive testst-
174
+ han children who are less fit (10, 11) and our study extends
175
+ this finding to school going children from a disadvantaged
176
+ background.
177
+ Among the various cognitive tests, significant posi-
178
+ tive association was found between aerobic capacity and
179
+ cognitive measures of both verbal (comprehension) and
180
+ performance tasks (block design). Previous studies have
181
+ shown that particular types of cognitive abilities are sensi-
182
+ tive to benefits of aerobic fitness (2, 12). Though the ex-
183
+ act mechanistic pathways through which physical fitness
184
+ impacts cognitive functions have not been ascertained,
185
+ various explanations have been put forward. A child’s fit-
186
+ ness may reflect the child’s overall health, which in turn
187
+ may positively impact the child’s cognitive performance
188
+ (13). In addition, movement particularly in young children
189
+ stimulates cognitive development (14). Recent research
190
+ has also shed light on the possible neural mechanisms in-
191
+ volved. Animal studies have shown that aerobic activity
192
+ increased capillary blood flow to the cortex and promote
193
+ growth of new neurons and synapses, resulting in better
194
+ performance (15, 16).
195
+ The findings in this small study of a modest positive
196
+ association between physical fitness and cognitive mea-
197
+ sures among school going children from economically
198
+ disadvantaged background is in agreement with earlier
199
+ studies. Future studies on larger sample of children with
200
+ more comprehensive measures of both physical fitness
201
+ and cognitive functions are clearly needed including ex-
202
+ ploring dose-effect relationship between physical fitness
203
+ and cognitive performance. This is especially important
204
+ given that a large number of children from developing
205
+ countries fail to reach their optimal cognitive poten-

+ ABSTRACT
49
+ Aim of the study: To apprehend the incidence of pre-diabetes and high risk for Type 2 diabetes mellitus (T2DM)
50
+ among adults of Bengaluru, South-India.
51
+ Materials and method: Six week’s house hold sector based survey (N=307; 23-70 years), was conducted in City
52
+ armed reserve police quarters, Chamrajpet, Bengaluru, Mysore road. Fasting and postprandial blood glucose
53
+ levels were checked using Hemocue 201+ blood glucose monitor device. In addition, body weight and body mass
54
+ index were assessed. Categorization of screened subjects based on the risk for T2DM was done using Indian
55
+ Diabetes Risk Score (IDRS) screening form. Of a total 1250 residents, almost one-fourth of them (n-307) had
56
+ taken part in the survey.
57
+ Results: Study resulted in identifying people with normal glucose tolerance or non-diabetes (n=178), impaired
58
+ fasting glucose or pre-diabetes (n=75), and T2DM (n=49) and newly diagnosed diabetes (n=5). Although, among
59
+ the screened, the incidence of pre-diabetes was accounted for 24%, with one-half (n=37, 49%) of them found at
60
+ high risk for type 2 diabetes. Age and gender matched data obtained from the screening postulated higher body
61
+ mass index (BMI) (p<0.001) and waist circumference (p<0.001) as most contributing factors increasing the
62
+ incidence of high risk for T2DM among the study population.
63
+ Conclusion: This survey manifested a higher incidence of pre-diabetes and high risk for T2DM among the study
64
+ population, which is linked to the anthropometric measures.

+ INTRODUCTION
75
+ The incidence and prevalence of type 2 diabetes and prediabetes is increasing worldwide[1] and is found closely
76
+ associated with industrialization, modernization and socioeconomic factors.[2] Reports also highlight that along
77
+ with growing incidence and prevalence, cost expenditure of diabetes care is also high[3] which emphasizes the
78
+ need for early detection and adopting appropriate therapies for prevention and effective management of type 2
79
+ diabetes mellitus. Few known reasons for such a huge rise in the prevalence is stipulated as low health awareness or
80
+ ignorance, sedentary life style,[4] abnormalities in the metabolism of carbohydrates, fats and protein, inadequate or
81
+ impaired secretion[5] and utilization of insulin.[6] In association with the rise in the prevalence, need for regular blood
82
+ glucose monitoring for early detection of risk for diabetes, the phase also known as prediabetes,[7] characterized by
83
+ impaired fasting glucose, is inevitable.
84
+ Madras Diabetes Research Foundation (MDRF), Chennai had developed Indian Diabetes Risk score (IDRS)[8] as
85
+ a screening tool to identify the risk for diabetes. Studies have been done using IDRS as a simple, [9] non-expensive
86
+ screening tool comprising of 4 different parameters age, family history, physical activity[10] and abdominal
87
+ obesity and the current study used IDRS as a screening tool to categorize the screened subjects based on risk for
88
+ T2DM.[11] Conclusive evidences suggest that physical inactivity <150 minutes/ week[12] subject an individual to
89
+ higher anthropometric measures which is a leading cause for metabolic disorders like prediabetes with progressive
90
+ loss of beta cell activity leading to impaired secretion of insulin,[13] insulin resistance resulting in the onset of
91
+ T2DM.[14] Dietary changes,[15] sedentary behavior, abdominal obesity[16] and overweight[17] are highest known
92
+ triggers resulting in inflated incidence and prevalence of prediabetes[18] and T2DM[19] and we used a demographic
93
+ data sheet involving all these factors to assess the role of the said factors in the incidence of prediabetes and high
94
+ risk for T2DM.
95
+ Cross sectional study reports a higher prevalence of prediabetes than T2DM[20] narrowing down the need for such
96
+ studies exclusively in Southern states of India[21], postulating a need for early detection among Indians, specially
97
+ among South Indians, to adopt appropriate measures to delay the onset of T2DM. Moreover, 50% of adults with
98
+ prediabetes[22] and a few percentage even with symptoms of Type 2 Diabetes in India remain unaware[23] and get
99
+ detected with complications at the time of diagnosis, which extrapolates the importance of early detection through
100
+ periodic large scale screening. Keeping the above mentioned factors in the background, the present study was
101
+ conducted to estimate the incidence of prediabetes and the prevailing factors resulting in risk for T2DM among
102
+ adults of Bengaluru.
103
+
104
+ MATERIALS AND METHODS
105
+ The total population of the quarters included 1,250 police personals and family members excluding minors. Among
106
+ which, one-fourth of them had volunteered to take part in the survey and who found fitting into the set inclusion
107
+ exclusion criteria ever (N= 307, aged range: 23 and 60 years, with an average age of 41.5 ± 11.2 years) (Figure 1)
108
+ were screened. The sampling technique used was Quota sampling.

+ Data collection
118
+ Inclusion and Exclusion criteria
119
+ Male and female adults who are residents of the police quarters for more than 10 years, willing to take part in the
120
+ survey were included. People who were below 18 and above 70 years of age, physically and mentally challenged,
121
+ with a history of systemic disorders, diabetes complications, handicapped or amputated, Physically inactive,
122
+ frequently on night shifts, known alcoholics and consuming more than 5 servings of beverages a day were excluded
123
+ from the survey. The study protocol was approved by Institutional Ethical Committee of S-VYASA (Deemed-to-be-
124
+ University) and signed informed consent was sought before the data collection.
125
+ Assessments
126
+ The assessments included glycemic parameters like Fasting and post prandial capillary blood glucose,
127
+ anthropometric measures like Body weight, height, Body mass index and waist circumference. Glycemic
128
+ parameters were checked on Hemocue glucose 201+ glucose monitoring internally powered equipment 6VDC,
129
+ catalogue # 1221142161, Sweden). Cuvette boxes were carried by the researchers in ice packs and were opened and
130
+ used only when the subject indicated that he/she is ready for it, to ensure quality of the Cuvette and to avoid
131
+ quantitative errors. Risk for diabetes was examined using IDRS: 0-29 low risk; 30-59 medium risk; >60 high risk for
132
+ T2DM. In addition, demographic data sheet DDS) comprising of information like age, gender, house number, lane,
133
+ race, duration of stay in the quarters, how many members being with diabetes and known prediabetes, mode and
134
+ duration of physical activity, diet pattern and preference, sleep quality, and willingness to take part in such surveys if
135
+ conducted ahead were filled by the eligible subjects.
136
+ Residents were informed about the survey two weeks in prior through flyer and pamphlets, and the need to be on
137
+ empty stomach for Capillary Fasting Blood Glucose (CFBG) reading and tentative date and day of data collection
138
+ upon each of the 18 sectors. In addition, a reminder was given by the researchers through sector wise home visit on a
139
+ day prior to the data collection. The timing of screening was 6:30 am to 10:30 am on all the days. CFBG was tested
140
+ after 8-12 hours of overnight fasting and Capillary post prandial blood glucose (however, identifying pre-diabetes
141
+ was only based on CFBG) was checked within one and a half to two hours of breakfast.
142
+ Screening process
143
+ The interested volunteers were also asked to fill up Demographic Data Sheet (DDS) which included questions like
144
+ the individual’s age, gender, house and lane number, pattern of diet, job, job timings, stress, physical activity (PA),
145
+ preferred mode of indoor and outdoor activity, duration of PA, health awareness, self-updating with health
146
+ checkups, sleep, intake of coffee, tea, soft drinks, alcohol and smoking. IDRS screening form was distributed and
147
+ except for waist circumference and height, subjects filled all other questions by self during their wait to get the
148
+ fasting blood glucose check done. Prediabetes subjects were identified based on FBG (100 to 125 mg/dl) only.
149
+ Ethical clearance and informed consent
150
+ Ethical approval was sought from S-VYASA’s ethical committee and all the rules were followed before, during and
151
+ post the data collection (coding the data). Data was not collected from the volunteers who denied to sign the consent.

+ RESULTS
171
+ Baseline characteristics
172
+ Screening resulted in identifying 3 groups based on the glucose tolerance and intolerance. Group 1 comprised of
173
+ people with impaired glucose tolerance/ T2DM (CFBG: 174.4± 43.9mg/dl; CPPBG 216.9± 55.4mg/dl) among
174
+ which a few were newly diagnosed as Type 2 diabetes (n=5; CFBG 178.4±37 mg/dl; CPPBG 226.2±58.1 mg/dl)
175
+ (Table 2). Group 2 consisted of one-fourth of the total screened subjects who were found with impaired fasting
176
+ glucose/ prediabetes (n=75, CFBG: 113.1±6.7mg/dl) among which except for two all others were newly diagnosed.
177
+ More than half of the subjects who belonged to Group 3, were found with normal glucose tolerance (n=178; CFBG
178
+ 84.3±8.5mg/dl; CPPBG 111±20.9mg/dl). Demographic data showed more or less same range of age among the
179
+ subjects of three groups (Table 1). Furthermore, the incidence of prediabetes is estimated as 24%, with an equal
180
+ distribution across the gender. However, almost half of the total prediabetes (n= 37, 27%) were identified at high
181
+ risk for T2DM as assessed by IDRS. On the other hand, the incidence of type 2 diabetes was estimated as 9.3%
182
+ (n=5) (Table 2).

445
+ DISCUSSION
446
+ This survey was conducted with an aim to assess the incidence of prediabetes and high risk for type 2 diabetes
447
+ among adults of South India. Secondary objectives of the study were to identify the factors increasing the risk for
448
+ diabetes and incidence of prediabetes among the study population. The results of the study substantially exhibited
449
+ body mass index and waist circumference as highest contributors increasing the incidence of prediabetes, whereas
450
+ the non-modifiable factor like age and family history were also found equally significant on a wider view.
451
+ Logistic regression conducted on the data of this study statistically evaluated the accuracy of IDRS as a screening
452
+ tool in identifying risk in terms of sensitivity, which indicates the true positive outcome of the data, confirmation of
453
+ made through the scores of Area of ROC curve (AUC) as low in rightly identifying the risk among group 1 and 3.
454
+ True negative outcome of the data as shown by the specificity scores and false positive scores are calculated by
455
+ applying a formula one minus specificity. Confirmation of the result outputs are sought from F and H measures
456
+ which are based on harmonic mean of precision and recall scores. Study published in 2019 supports the same.[24]
457
+ Study published in 2020 shows the prevalence of diabetes is 13.2% and that of prediabetes as 15.5%.[25] Whereas,
458
+ the present study reports the incidence of prediabetes as 27%, and that of the undiagnosed type 2 diabetes as 9.3%,
459
+ among adults of Bengaluru. This survey outcome thus plights the need for verifying the score distribution towards
460
+ the factors of IDRS and points out a need for verifying the risk assessments with additional tools along with IDRS.
461
+ The study is of high social relevance as it could find high risk for incidence of prediabetes among adults of
462
+ Bengaluru, one of the states in South India. To summarize, this study projects the need for further large scale survey
463
+ studies to get an estimate of incidence of prediabetes and high risk for diabetes across different states of South India.
464
+
465
+ CONCLUSION
466
+ This study orients on the increasing incidence of prediabetes and undiagnosed type 2 diabetes among adults of
467
+ South India and projects the need for large scale screening involving appropriate screening methods to identify
468
+ the risk factors too. As this study assessed Body mass index and waist circumference, in addition to the non-
469
+ modifiable factors like family history and age, as most prevailing risk factors further studies should aim at finding
470
+ other factors as well. The result of this study also highlights the need for awareness programs through interventional

+ Abstract
20
+ Objectives
21
+ In ancient yoga texts there are two meditative states described. One is dharana, which requires focusing, the second is
22
+ dhyana, during which there is no focusing, but an expansive mental state is reached. While an earlier study did show
23
+ improved performance in an attention task after dharana, the autonomic changes during these two states have not been
24
+ studied.
25
+ Methods
26
+ Autonomic and respiratory variables were assessed in 30 healthy male volunteers (group mean age±SD, 29.1±5.1 years)
27
+ during four mental states described in traditional yoga texts. These four mental states are random thinking (cancalata),
28
+ nonmeditative focusing (ekagrata), meditative focusing (dharana), and effortless meditation (dhyana). Assessments
29
+ were made before (5 minutes), during (20 minutes), and after (5 minutes), each of the four states, on four separate days.
30
+ Results
31
+ During dhyana there was a significant increase in the skin resistance level (p<0.001; post hoc analysis following
32
+ ANOVA, during compared to pre) and photo-plethysmogram amplitude (p<0.05), whereas there was a significant
33
+ decrease in the heart rate (p<0.001) and breath rate (p<0.001). There was a significant decrease in the low frequency
34
+ (LF) power (p<0.001) and increase in the high frequency (HF) power (p<0.001) in the frequency domain analysis of the
35
+ heart rate variability (HRV) spectrum, on which HF power is associated with parasympathetic activity. There was also a
36
+ significant increase in the NN50 count (the number of interval differences of successive NN intervals greater than 50 ms;
37
+ p<0.001) and the pNN50 (the proportion derived by dividing NN50 by the total number of NN intervals; p<0.001) in
38
+ time domain analysis of HRV, both indicative of parasympathetic activity.
39
+ Conclusions
40
+ Maximum changes were seen in autonomic variables and breath rate during the state of effortless meditation (dhyana).
41
+ The changes were all suggestive of reduced sympathetic activity and/or increased vagal modulation. During dharana
42
+ there was an increase in skin resistance. The changes in HRV during ekagrata and cancalata were inconclusive.

50
+ Introduction
51
+ MEDITATION IS RECOGNIZED AS a specific consciousness state in which deep relaxation and increased internalized
52
+ attention co-exist.
53
+ There are widely differing methods, involved in different meditations, though the practices are intended to have a common
54
+ end result (viz., a calm, yet alert mind). This is supported by research from the late 1960s, since when there have been
55
+ investigations on the effects of meditation in experienced as well as inexperienced meditators.
56
+ In certain cases
57
+ meditators practicing the same technique showed opposite trends of results, particularly for recordings of the
58
+ electroencephalogram (EEG) and autonomic variables. Some studies showed that meditation practice is associated with
59
+ reduced sympathetic activity, whereas other studies reported increased sympathetic activity. For three meditation
60
+ techniques in particular, the results appeared suggestive of both increased arousal (in some cases) and reduced arousal
61
+ (in others). These are Transcendental Meditation (TM), Zazen meditation, and Ananda Marga meditation. These are
62
+ described in detail in following text.
63
+ In a previous study practitioners of TM showed a decrease in oxygen consumption, reduced heart and breath rates,
64
+ lower blood lactate levels, and an increase in slow alpha and occasional theta in the EEG after 20 minutes of practice,
65
+ suggestive of a quietening effect. In fact most of the studies on TM reported changes suggestive of increased autonomic
66
+ stability and sympathetic withdrawal. In addition, Dillbeck and Orme-Johnson, carried out a meta-analysis of 31
67
+ studies evaluating the effect of meditation on reducing somatic arousal. The studies showed reduced somatic arousal with
68
+ some physiological changes suggestive of increased alertness. The findings of increased alertness was supported by a
69
+ study by Lang et al. In this study meditators who had 2 to 3 years of experience practicing TM had lower 24-hour
70
+ urinary catecholamines compared to meditators with an average experience of 4.1 years. The findings contradict the idea
71
+ that meditation is simply a state of reduced sympathetic activity but supports the idea of it being a “calm yet alert” state.
72
+ Similar findings (increased as well as decreased arousal) were also reported for the eyes open, Zazen meditation. In
73
+ 1960, Hirai reported an increase in heart rate during Zazen meditation, whereas Sugi and Akatsu found a decrease in
74
+ oxygen consumption in Zazen meditators. Hence the first report was suggestive of activation while the second report was
75
+ suggestive of relaxation.
76
+ Similarly, two reports were also found for Ananda Marga meditation, which involves intense concentration. In one report
77
+ during the meditation, the expert meditators showed an increase in skin conductance and absence of a deceleratory heart
78
+ rate orienting response. These findings challenged a relaxation model for Ananda Marga meditation, which showed an
79
+ increase in galvanic skin resistance, a decrease in breath rate, and a more stable EEG in another study.
80
+ Hence, these early studies on different meditation techniques did not support a single model of meditation as either
81
+ activating or relaxing. Findings like these gave rise to meditation being described as a state of “alertful rest,” a description
82
+ first used by researchers studying TM, and later used for other meditation techniques as well.
83
+ Relatively recently there was a report which described three broad categories of meditation techniques and their EEG
84
+ patterns.
85
+ The three categories were (1) focused attention, which involves voluntary and sustained attention on the
86
+ chosen object, (2) open monitoring meditation in which there is nonreactive monitoring of the moment-to-moment content
87
+ of experience, and (3) automatic self-transcending, which includes techniques intended to transcend their own activity.
88
+ Overall the report suggests that there exist differences in objective assessments in meditation techniques which differ in
89
+ their methods and principles.
90
+ The concept of meditation described in ancient yoga texts fits in with the categories of meditation experience mentioned
91
+ above. In Patanjali's Yoga Sutras (circa 900 BC), there are two meditative states described, one leading to the other.
92
+ The first stage is dharana (or focusing with effort), confining the mind within a limited mental area (“desha-
93
+ bandhashchittasya dharana”; Patanjali's Yoga Sutras, Chapter III, Verse 1).
94
+ The next stage is dhyana or effortless
95
+ expansion (“tatra pratyayaikatanata dhyanam”; Patanjali's Yoga Sutras, Chapter III, Verse 2).
96
+ This state is
97
+ characterized by the uninterrupted flow of the mind towards the object chosen for meditation. The practice of dharana is

116
+ Go to:
117
+ supposed to precede dhyana.
118
+ Dharana and dhyana may be considered as the last two of four stages which form a continuum in the process and
119
+ practice of meditation. The first two stages are described in another ancient text (the Bhagavad Gita, compiled circa
120
+ 500 BC). The first stage is cancalata, which is a stage of random thinking.
121
+ The second stage is ekagrata, during
122
+ which the attention is directed to a series of associated thoughts.
123
+ If a person chooses to think thoughts related to
124
+ meditation, the person would then be able to progress to the next two stages, dharana and dhyana.
125
+ The performance in a cancellation task was compared in 70 normal healthy male volunteers at the beginning and end of
126
+ the four types of sessions (viz., cancalata, ekagrata, dharana, and dhyana).
127
+ The performance in this task improved
128
+ significantly after dharana (which can be considered a state of meditative focusing) and was worse after cancalata (or
129
+ random thinking), suggesting better attention after dharana.
130
+ There has been no study comparing the four mental states using autonomic and respiratory variables. Hence, the present
131
+ study was planned to assess the changes in autonomic and respiratory variables in normal healthy volunteers before,
132
+ during, and after the four types of sessions (cancalata, ekagrata, dharana, dhyana) on separate days. These mental
133
+ states are descriptions from the ancient yoga texts and studying them was hoped to increase the understanding about
134
+ meditation including differences seen in earlier studies.
135
+ Materials and Methods
136
+ Participants
137
+ There were 30 male volunteers with ages ranging from 20 to 45 years (group mean age±SD, 29.1±5.1 years) who were
138
+ residing at a yoga center in south India. All of them had normal health based on a routine case history and clinical
139
+ examination. An electrocardiogram (EKG) recording showed that none of them had extra systoles or any abnormality in
140
+ the EKG. They were not on any medication or using any other wellness strategy. The other predetermined conditions to
141
+ exclude participants from the trial were any chronic illness, particularly psychiatric or neurological disorders. Male
142
+ volunteers alone were selected as autonomic and respiratory variables are known to vary with the phases of the
143
+ menstrual cycle.
144
+ All the meditators had been practicing meditation on the Sanskrit syllable Om for 30 minutes each
145
+ day, 4 days a week. They had a minimum of 6 months of experience in meditation on the syllable Om (group average
146
+ experience±SD, 20.95±14.21 months). Apart from their prior experience of meditation on Om, they were given a 3-
147
+ month orientation program under the guidance of an experienced meditation teacher.
148
+ All participants expressed their willingness to take part in the experiment. The study was approved by the institution's
149
+ ethics committee. The study protocol was explained to the subjects, and their signed consent was obtained.
150
+ Design of the study
151
+ Each participant was assessed in four sessions. Two of them were meditation sessions (dharana [meditative focusing]
152
+ and dhyana [meditative defocusing or effortless meditation]) and two of them were control sessions (ekagrata
153
+ [nonmeditative focused thinking] and cancalata [random thinking]). All four sessions consisted of three states: pre (5
154
+ minutes), during (20 minutes), and post (5 minutes). Assessments were made on four different days, which were not
155
+ necessarily on consecutive days, but at the same time of the day. The allocation of participants to the four sessions was
156
+ random using a standard random number table. This was done so as to prevent the influence of being exposed to the
157
+ laboratory for the first time, from influencing the results. In the cancalata session participants were asked to allow their
158
+ thoughts to wander freely. This was facilitated as they were listening to a compiled audio CD consisting of brief periods
159
+ of conversation on multiple subjects recorded from a local radio station. In the ekagrata session, participants were
160
+ asked to focus on a single topic (i.e., listening to a lecture on meditation). In the dharana session participants were asked
161
+ to focus on the Sanskrit syllable Om, whereas in the dhyana session participants moved effortlessly from thinking about
162
+ Om, to quiet absorption in the single thought of Om (i.e., dhyana). Instructions for dharana and dhyana were played
163
+ from compiled audio CD. The duration of all the four sessions was 20 minutes. The study design is schematically

183
+ Assessments
184
+ Autonomic variables and respiration were assessed in the four sessions using a four-channel polygraph (Polyrite D,
185
+ Recorders and Medicare Systems, Chandigarh, India).
186
+ Respiration was recorded using a volumetric pressure transducer fixed around the trunk about 8 cm below
187
+ the lower costal margin as the participants sat erect.
188
+ The EKG was recorded using a standard bipolar limb lead II configuration and an
189
+ AC amplifier with 100-Hz high cut filter and 1.5-Hz low cut filter settings. The EKG was digitized using a 12-bit analog-
190
+ to-digital converter (ADC) at a sampling rate of 1024 Hz and was analyzed off-line to obtain the heart rate variability
191
+ (HRV) spectrum.
192
+ The photo-electric transducer was placed on the volar surface of the distal phalanx of
193
+ the left thumb with the light emitting diode facing the volar surface. The digit pulse volume was recorded and presented as
194
+ microvolts. The amplitude of the pulse wave was used to record digit pulse volume which was presented as microvolts.
195
+ Skin resistance was recorded using Ag/AgCl electrodes with electrode gel placed in contact with the
196
+ volar surfaces of the distal phalanges of the index and middle fingers of the left hand. A low level DC preamplifier was
197
+ used and a constant current of 10 μA was passed between the electrodes.
198
+ Interventions
199
+ Throughout all sessions participants sat cross legged and kept their eyes closed following prerecorded instructions. An
200
+ emphasis was placed on carrying out the practices slowly, with awareness of physical and mental sensations, and
201
+ relaxation. Participants were given a 3-month meditation orientation program under the guidance of an experienced
202
+ meditation teacher. The purpose of this orientation was for all participants to practice the two different states of
203
+ meditation, viz., dharana and dhyana based on specific instructions. The evaluation of the participants' practice of
204
+ dharana and dhyana was based on their self-report as well as consultations with the meditation teacher. A brief
205
+ description of each session is given in the following sections.
206
+ Participants were asked to allow their thoughts to wander freely as they listened to a
207
+ compiled audio CD consisting of brief periods of conversation, announcements, advertisements, and talks on multiple
208
+ topic recorded from a local radio station transmission. All these conversations were unconnected and were believed to
209
+ induce a state of random thinking.
210
+ Participants listened to a prerecorded lecture on meditation. This was not
211
+ about meditation, on the Sanskrit syllable Om, but about meditation, in general. It was speculated that listening to a
212
+ lecture on a particular topics could induce the state of nonmeditative focused thinking.
213
+ Participants were asked to follow the audio instructions for the practice of dharana. The
214
+ meditative focusing on the Sanskrit syllable Om consisted of mental visualization of the symbol Om. Dharana involves
215
+ conscious effort to keep the thoughts restricted to those given in the instructions.
216
+ Participants were asked to follow the audio instruction for the
217
+ practice of dhyana. They were supposed to absorb with the object of meditation without any effort. Dhyana involves
218
+ effortless defocusing induced by mental chanting of Om.

223
+ Go to:
224
+ After each session participants were asked to rate their ability to comply with instructions on a scale from 0 to 10. Only
225
+ those who achieved 7.5 (75%) and more were included in the study. None of the sessions had to be excluded for this
226
+ reason.
227
+ Data extraction
228
+ The following data were extracted from the polygraph. The respiratory rate in cycles per minute (cpm) was calculated by
229
+ counting the breath cycles in 60-second epochs, continuously. The heart rate in beats per minute (bpm) was calculated
230
+ by counting the R waves of the QRS complex in the EKG in 60-second epochs, continuously. The skin resistance was
231
+ obtained at 20-second intervals, continuously and expressed in kilohms (kΩ). The amplitude of the digit pulse volume
232
+ was sampled from the peak of the pulse wave at 30-second intervals and presented in microvolts.
233
+ Frequency domain and time domain analysis of HRV data was carried out for 5-minute recordings for each of the
234
+ following sessions (cancalata, ekagrata, dharana, dhyana). These 5-minute epochs were recorded for pre, during,
235
+ and post sessions. Pre and post sessions had one epoch of 5 minutes, whereas during had four similar epochs (viz. D1,
236
+ D2, D3, D4). The data recorded were visually inspected off-line and only noise-free data were included for analysis. The
237
+ data were analyzed with an HRV analysis program developed by the Biomedical Signal Analysis Group (University of
238
+ Kuopio, Finland).
239
+ The energy in the HRV series in the following specific frequency bands was studied viz., the very
240
+ low frequency band (0.0–.05 Hz), low frequency (LF) band (0.05–0.15 Hz), and high frequency (HF) band (0.15–0.5
241
+ Hz). The LF and HF band values were expressed as normalized units.
242
+ The following components of time domain HRV
243
+ were analyzed: (1) mean RR interval (the mean of the intervals between adjacent QRS complexes or the instantaneous
244
+ heart rate), (2) RMSSD (the square root of the mean of the sum of the squares of differences between adjacent NN
245
+ intervals), (3) NN50 (the number of interval differences of successive NN intervals greater than 50 milliseconds), and (4)
246
+ pNN50 (the proportion derived by dividing NN50 by the total number of NN intervals).
247
+ Data analysis
248
+ Statistical analysis was done using SPSS Inc. (Chicago, USA) (Version 16.0). Repeated measures analysis of variance
249
+ (ANOVA) were performed with two “within subjects” factors (i.e., Factor 1: Sessions; cancalata, ekagrata, dharana,
250
+ and dhyana, and Factor 2: States; Pre, During [D1, D2, D3, D4], and Post). This was followed by a post hoc analysis
251
+ with Bonferroni adjustment for multiple comparisons between the mean values of different states (Pre, During and Post)
252
+ and all comparisons were made with the respective Pre state.
253
+ Results
254
+ The group mean values±SD for breath rate, heart rate, photo-plethysmogram amplitude, and skin resistance are given in
255
+ Table 1. Frequency domain and time domain measures of HRV are given in Table 2 and Table 3, respectively.

286

288
+ Maximum changes in autonomic variables and the breath rate occurred during the stage of effortless meditation (dhyana).
289
+ The changes were all suggestive of reduced sympathetic activity and/or increased vagal modulation. These were a
290
+ decrease in heart rate, an increase in digit pulse volume (based on the photo-plethysmogram amplitude), an increase in

+ skin resistance, a decrease in the LF power of HRV, and an increase in the HF power, also an increase in NN50 and
292
+ pNN50, with a reduction in breath rate.
293
+ The main difference between dharana and dhyana sessions was apparent in the autonomic variables and breath rate. As
294
+ described above, most of the changes during dhyana were suggestive of reduced activity in the different subdivisions of
295
+ sympathetic nervous system activity, though some variables are regulated by several factors. The heart rate for example,
296
+ is regulated by dual innervation (sympathetic and vagal), as well as humoral factors.
297
+ This makes the decrease in heart
298
+ rate less easy to interpret (i.e., it could be due to increased vagal tone or due to sympathetic withdrawal). This also
299
+ applies to HRV components.
300
+ There was a general understanding that the LF band of the HRV is an index of cardiac sympathetic activity.
301
+ However,
302
+ this has been debated. Neither the LF band (<0.15 Hz) nor the HF band (>0.15 Hz) are considered exclusive markers of
303
+ sympathetic or parasympathetic tone, respectively.
304
+ The HRV represents the integrated end-organ response to the
305
+ complex nonlinear interaction between the two divisions of the autonomic nervous system as well as other factors. This
306
+ particularly applies to the relationship between the LF power and cardiac sympathetic tone. It was found that the LF
307
+ power was reduced by selective cardiac parasympathectomy and was not totally removed when β-adrenoceptor
308
+ blockade was combined with denervation.
309
+ Also activities that were expected to increase sympathetic activity failed to
310
+ increase the LF power and actually significantly reduced the LF power. In fact sympathetic activity can also modulate the
311
+ HF component of HRV, though to a lesser extent than the parasympathetic influence on the LF power. The association
312
+ between HF power and cardiac parasympathetic activity is stronger. However the association is qualitative rather than
313
+ quantitative. Hence the HRV provides a qualitative marker of cardiac parasympathetic regulation and changes in the LF
314
+ power and LF/HF ratio have to be viewed with caution.
315
+ The LF power significantly increased during random thinking (cancalata) and nonmeditative focusing (ekagrata), while

321
+ Changes in Autonomic Variables Following Two Meditative States Described in Yoga Texts
322
+ http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3546358/
323
+ 7/10
324
+ there was a significant decrease during meditation (dhyana). Conversely, the HF power increased during meditation
325
+ (dhyana), while it was decreased during nonmeditative focusing (ekagrata). The increase in LF during ekagrata and
326
+ cancalata could reflect either a change in sympathetic or parasympathetic activity as described above. Given the
327
+ complexity in interpreting these changes, at this stage it may be said that the change in LF in ekagrata and cancalata
328
+ reflects a change in autonomic activity that would need further investigation. The frequency domain analysis indicated a
329
+ possible increase in parasympathetic activity based on the increase in HF power in dhyana alone. This is supported by
330
+ the changes in the HRV with time domain analysis. The pNN50 and the NN50 are both indicative of vagal tone.
331
+ Both
332
+ values increased during dhyana, which was also suggestive of parasympathetic dominance. Hence during dhyana there
333
+ was a shift in the autonomic balance towards vagal dominance.
334
+ The skin resistance level is an indicator of the level of activity in the cholinergic sudomotor sympathetic nerves supplying
335
+ the eccrine sweat glands.
336
+ This is believed to be the main contributor to changes in the spontaneous electrodermal
337
+ activity.
338
+ The increase in the skin resistance level in all four sessions suggests relaxation during all of them.
339
+ An increase in photo-plethysmogram amplitude correlates with decreased noradrenergic vasomotor sympathetic control
340
+ of the cutaneous blood vessels.
341
+ Hence during the dhyana session there was decreased activity in the sympathetic
342
+ nerves supplying the cutaneous blood vessels.
343
+ Unlike these variables the breath rate depends upon numerous factors ranging from the level of physical activity to
344
+ psychological stress.
345
+ A decrease in breath rate is generally associated with relaxation, which can explain the decrease
346
+ seen during dhyana. The increase in breath rate during cancalata could suggest that participants found the diverse
347
+ auditory inputs (taken from a local radio station and put together at random) stressful.
348
+ Taken together the results suggest that effortless meditation or dhyana is associated with changes in the autonomic
349
+ nervous system suggesting vagal dominance. Hence earlier studies that gave contrasting results (i.e., of sympathetic
350
+ withdrawal in some studies, while other studies showed sympathetic activation), when meditators practiced the same
351
+ technique may have been due to some meditators being in the dharana phase, while others were in the dhyana phase.
352
+ Examples for this are Ananda Marga Meditation, for which one study reported sympathetic withdrawal,
353
+ while another
354
+ study reported increased sympathetic activity in meditators. Similarly there were conflicting reports for Zazen
355
+ meditation.
356
+ A TM session has been shown to consist of phenomenologically and physiologically distinct substates.
357
+ The three
358
+ qualitatively different substates that have been described are (1) the inward stroke in which there is progressive reduction
359
+ of all activity, (2) transcendental consciousness in which thoughts are absent yet consciousness is maintained, and (3) the
360
+ outward stroke in which mental and physical activity progressively increase.
361
+ These three substates or phases have
362
+ easily measured markers.
363
+ It was observed that meditators went through the three phases several times in a session.
364
+ However, it was possible to note that the inward stroke was characterized by less heart rate deceleration and lowered
365
+ skin conductance compared to the state of transcendental consciousness. Hence, in different phases of meditation,
366
+ sympathetic activity may differ. This is similar to the present results. These differences during a meditation session could
367
+ also be the reason for the apparently contradictory results seen in Ananda Marga and Zazen meditators. Also the
368
+ differences could be due to the fact that different techniques are often given the same name.
369
+ In summary, the changes were hence suggestive of reduced activation in dhyana. However dhyana is not the ultimate
370
+ stage described in the ancient texts. Following dhyana, the eighth step in the astanga (eight limbs) yoga of Patanjali is
371
+ samadhi which means, the state of ultimate realization. Samadhi has two stages, sabija samadhi (bija=seed, in
372
+ Sanskrit), which means realization in its seed or unmanifest form (Patanjali's Yoga Sutras, Chapter I, Verse 50). With
373
+ continued practice this leads to nirbija samadhi or the manifest state of ultimate realization (Patanjali's Yoga Sutras,
374
+ Chapter I, Verse 51).
375
+ There have been studies that have attempted to find objective physiological correlates for the experience of pure
376
+ awareness as in samadhi. In 40 meditators practicing the TM technique, 11 participants were chosen to press a button

398
+ Breath suspension periods when experiencing pure consciousness in TM were correlated with increased total EEG
399
+ coherence with implications for functional integration and better mind–body health, along with reduced heart rate and
400
+ phasic skin conductance responses.
401
+ In summary, the present results show that when meditation is divided as two traditionally described stages, meditative
402
+ focusing (dharana) and meditative defocusing (dhyana), the changes in the autonomic nervous system are distinct and
403
+ different. The present findings make it apparent that studying yoga practices using present-day scientific methods may be
404
+ made more meaningful if the techniques are understood based on the descriptions in the traditional texts.
405
+ Conclusions
406
+ Maximum changes were seen in autonomic variables and breath rate during the state of effortless meditation (dhyana).
407
+ The changes were all suggestive of reduced sympathetic activity and/or increased vagal modulation. During dharana
408
+ there was an increase in skin resistance. The changes with HRV during ekagrata and cancalata were inconclusive.

+ Abstract
19
+ Background:
20
+ The purpose of this study was to observe the effect of bhastrika pranayama (bellows breath) and
21
+ exercise on lung function of healthy individuals.
22
+ Materials and Methods:
23
+ A total of thirty male participants were recruited and randomly divided into two groups, i.e., yoga
24
+ breathing group (YBG, n = 15) and physical exercise group (PEG, n = 15), and the participants’ ages
25
+ ranged between 18 and 30 years (group age mean ± standard deviation, 22.5 ± 1.9 years). YBG
26
+ practiced bhastrika pranayama for 15 min, whereas PEG practiced running for 15 min, 6 days in a
27
+ week, over a period of 1 month. The participants were assessed for (i) forced vital capacity (FVC), (ii)
28
+ forced expiratory volume in the first second (FEV1), (iii) peak expiratory flow rate (PEFR), and (iv)
29
+ maximum voluntary ventilation (MVV) functions of lungs.
30
+ Results:
31
+ Repeated-measures analyses of variance with Bonferroni adjustment post hoc analyses of multiple
32
+ comparisons showed that there was a significant increase in YBG for all variables, i.e., FVC, FEV1,
33
+ PEFR, and MVV (P < 0.001, P < 0.001, P < 0.01, and P < 0.001, respectively), whereas there was a
34
+ significant increase in PEFR and MVV (P < 0.05 and P < 0.01, respectively) only, among PEG.
35
+ However, the change in PEG was less of magnitude as compared to YBG.
36
+ Conclusions:
37
+ These findings demonstrate that incorporating pranayama in sports can enhance the efficiency of
38
+ healthy individuals and athletes by enhancing the ventilatory functions of lungs, especially for those
39
+ who partake in aerobic-based sports and require efficient lungs to deliver sufficient oxygen uptake.

+ Introduction
44
+ Breath regulation or control is crucial to the practice of yoga and is emphasized in later six out of the
45
+ eight aspects, or “limbs” of yoga as follows: yama (universal ethics), niyama (individual ethics), asana
46
+ (physical postures), pranayama (breath control), pratyahara (control of the senses), dharana
47
+ (concentration), dhyana (meditation), and samadhi (bliss).[1] Breath can be considered as the most
48
+ important function of the body for indeed all the other functions depend on it.[2] When the breath stops
49
+ permanently, life ends. Hence, prana (chi) or the breath is thus rightly called the life force energy.
50
+ Moreover, the technique of manipulation of the normal pattern of prana (breath) through its conscious
51
+ control is known as pranayama (yogic breathing exercise).[1] In view of its importance, the yogis from
52
+ times immemorial developed this special system “Pranayama” and emphasized on the need of its
53
+ regular practice. Its practice helps to reap maximum benefits by controlling the life force in a superior
54
+ and extraordinary way by harmonizing body, mind, and spirit.[3] Schünemann et al.[4] reported in their
55
+ study that pulmonary function is a long-term predictor of overall survival rates in both genders and
56
+ could be used as a tool in general health assessment.
57
+ In a previous study, Pramanik et al.[5] revealed that after slow bhastrika pranayamic breathing
58
+ (respiratory rate [RR] 6 breath/min) for 5 min, both the systolic and diastolic blood pressure decreased
59
+ significantly with a slight fall in heart rate. Raju et al.[6] studied pranayama effect among athletes in
60
+ two phases on exercise tests. Both phases, i.e., submaximal and maximal exercise tests revealed that
61
+ the participants practicing pranayama could achieve significantly higher work rates with a reduction in
62
+ oxygen consumption per unit work and without an increase in blood lactate levels. Another study
63
+ assessing the combined effect of both anulom vilom and bhastrika pranayama reported significant
64
+ improvement in vital capacity and maximal ventilator volume.[7]
65
+ Prakash et al.[8] in a cross-sectional study found that the yogis and athletes had significantly better
66
+ forced expiratory volume in the first second (FEV1). Further, yogis’ peak expiratory flow rate (PEFR)
67
+ was reported to be significantly better than that of both athletes and sedentary workers. Joshi et al.[9]
68
+ reported that 6 weeks of pranayama improved ventilatory functions by lowering RR, increasing the
69
+ forced vital capacity (FVC), FEV1, maximum voluntary ventilation (MVV), PEFR, and prolonging the
70
+ breath holding time. Similarly, another study demonstrated a significant increase in FVC, FEV1, PEFR,
71
+ and forced expiratory flow by 25%–75% after the practice of pranava, nadishuddi and savitri
72
+ pranayama.[10] Apart from this, there was a comparative study between slow (Nadisohana, Pranav
73
+ pranayama, and Savitri pranayama) and fast group pranayama (kapalabhati, bhastrika, and kukkriya)
74
+ after training of 12 weeks on pulmonary function in young healthy volunteers reporting improvement
75
+ in ventilatory functions.[11] Additionally, other comparative studies on slow and fast pranayama,
76
+ bhastrika was included as one of the practices of fast group had reported improvement in hand grip
77
+ strength and endurance,[12] reduced perceived stress and enhanced cognitive functions in healthy
78
+ subjects.[13] Furthermore, fast pranayama's additional effects on the executive function of
79
+ manipulation in auditory working memory, central neural processing, and sensory motor performance
80
+ were observed. Apart from this, there are also studies on mukha bhastrika (a bellow-type pranayama)
81
+ reporting decreased reaction time.[14]
82
+ However, all the previous studies had been limited to certain points such as (i) either combined effects
83
+ of slow/fast group pranayama were explored or pranayama effect was cumulatively investigated with
84
+ other multiple techniques of yoga practices, (ii) most studies were either done without a control group
85
+ or rarely control group was present, and (iii) retrospective studies were reported. And eventually, there
86
+ was no study which has examined bhastrika pranayama alone compared with exercise (running) on
87
+ ventilatory functions of the lung. Higher lung capacity has been speculated to be a key variable for
88
+ marathon performance in amateur runners in a previous study.[15] Hence, the present study aimed to
89
+ assess the impact of 4-week (1 month) bhastrika pranayama compared with running as active control
90
+ on four parameters of lung function, i.e., (i) FVC, (ii) FEV1, (iii) PEFR, and (iv) MVV on healthy
91
+ volunteers, who were actively involved in sport activities.
92
+ Materials and Methods
93
+ Participants
94
+ Thirty healthy male participants with ages between 18 and 30 years (group average age ± standard
95
+ deviation, 28.8 ± 7.8 years) were selected from North India. Only male participants were recruited in
96
+ the study as pulmonary capacity varies with gender due to the influence of the reproductive hormones
97
+ in females.[16] The sample size was calculated based on the FEV1 mean and standard deviation values
98
+ of a previous study.[17] The G*Power software,[18] Version 3.0.10 (Heinrich Heine Universität
99
+ Düsseldorf) was used, where alpha, power, and effect size were 0.05, 0.95, and 1.99 respectively,
100
+ which generated a sample size of 7 in each group. It was decided to recruit 15 participants in each
101
+ group to compensate for possible dropouts. Participants were randomly allocated using the web-based
102
+ Research Randomizer[19] into yoga breathing group (YBG; n = 15) and physical exercise group (PEG;
103
+ n = 15) after baseline data recording of the pulmonary function test (PFT). All participants were
104
+ healthy, based on a routine case history and clinical examination, and none of them were on
105
+ medication. They were actively involved in sports activities and ready to volunteer in the current study.
106
+ The participants were excluded who had a history of major medical illness such as tuberculosis,
107
+ hypertension, diabetes mellitus, bronchial asthma, history of major surgery in the recent past, smoking,
108
+ alcohol consumption, and nonvegetarian diet. The study design was explained to all the participants,
109
+ and their signed informed consent form was obtained. The study was approved by the Institutional
110
+ Ethics Committee of Dev Sanskriti University, Haridwar, India.
111
+ Design
112
+ It is difficult to assess yoga practices in double-blind trials because the intervention requires the active
113
+ participation of the individual and hence, the identities of the interventions become known after
114
+ allocation.[18] However, the investigator who did the PFT was blind to the intervention. Therefore, it
115
+ was a simple randomized controlled study. Consort flow diagram is explained in Figure 1.

123
+ Baseline data of each participant for the PFT were measured using a precalibrated computerized
124
+ spirometer-MEDSPIROR (RMS recorders and Med Sys Pvt. Ltd., Chandigarh, India) instrument by an
125
+ expert lab technician. Participants were properly familiarized with the testing procedure before each
126
+ test. The baseline and postdata recording was carried out in sitting position following a standard
127
+ procedure[20] during morning hours (6:30 am to 8:00 am). While performing a test, participants were
128
+ adequately encouraged to perform at their optimum level. The test was repeated three times, and the
129
+ highest value was used for the statistical analyses. All readings were recorded at saturated body
130
+ temperature and pressure.
131
+ For each measure, the maintenance of a tight seal between the lips and mouthpiece of the spirometer
132
+ was ensured. All participants were assessed on the following parameters:
133
+ In assessing FVC, participants were made to sit comfortably with normal
134
+ breathing, with the mouthpiece of a spirometer placed into the mouth. The participants were instructed
135
+ to inspire to their maximum effort and blow all the air through the mouthpiece as rapidly, forcefully,
136
+ and completely as possible.
137
+ FEV1 was the value in the first second of forceful
138
+ expiration derived from FVC.
139
+ For the PEFR, participants were instructed to perform forceful expiration
140
+ immediately after a full inspiration (i.e., with no postinspiratory pause). It is the maximum velocity in
141
+ liters per minute with which air is forced out of the lungs.[21]
142
+ For MVV assessment, participants were instructed to inhale and exhale
143
+ with a maximum voluntary effort by breathing as quickly and deeply as possible for 10–20 s, and
144
+ finally the highest volume from 10 to 20 s was corrected to 1 min.
145
+ Intervention
146
+ The YBG practiced bhastrika pranayama for 15 min, 6 days in a week for a month, in morning hour
147
+ approximately at 8 “o” clock. There was no training or orientation before the intervention as
148
+ participants were occasional practitioner of yogic practices. Bhastrika pranayama imitates the action of
149
+ the bhastra or “bellows” and fans the internal fire heating the physical and subtle bodies. Inhalation
150
+ and exhalation in this pranayama are equal and are the result of systematic and equal lung movements.
151
+ The inhalation and exhalation were performed with little force.[3] All participants were asked to sit in
152
+ any comfortable meditation pose, and bhastrika pranayama practice was started with Om chanting and
153
+ ended with pacifying chanting called shantipatha. Every day, participants were asked to practice three
154
+ rounds of bhastrika pranayama of 4–5 min each with approximately 1 min rest after each round. All
155
+ the participants were trained and monitored by a certified yoga trainer.
156
+ The practice of bhastrika pranayama with medium or fast pace continuously for longer duration is not
157
+ possible or very difficult, so volunteers were asked to start the practice with slow pace and gradually
158
+ increase the speed with full efforts toward the ending of approximately 5 min.
159
+ Similarly, participants in the PEG were asked to run for 5 min thrice in an open environment and
160
+ instead of complete rest, they were asked to walk as a rest in between approximately 1 min, after every
161
+ 5 min. PEG practiced running like YBG for 15 min, 6 days in a week for a month, in morning hour
162
+ approximately at 8:30 am. Initially, each participant was asked to run slowly and gradually increase
163
+ their speed to full effort toward the end of approximately 5-min practice. PEG was also monitored by
164
+ an investigator who was not involved in the analysis part.
165
+ Statistical analysis
166
+ Statistical analyses were performed using the Statistical Package for the Social Sciences (Version 18.0.
167
+ SPSS Inc., Chicago, IL, USA). Data of (i) FVC, (ii) FEV1, (iii) PEFR, and (iv) MVV recorded were
168
+ tested by Shapiro–Wilk test for normality, which showed that data were normally distributed.
169
+ Therefore, repeated-measures analyses of variance (ANOVA) were performed. There was one within-
170
+ subject factor, i.e., state (baseline and post) and one between-subjects factor, i.e., groups (YBG and
171
+ PEG). Post hoc analyses with Bonferroni adjustment were used to detect significant differences
172
+ between the mean values. Cohen's d effect size was calculated using G-power software (3.0.10
173
+ version).

271
+ Discussion
272
+ In the present study, FVC, FEV1, PEFR, and MVV increased significantly after the 1-month practice of
273
+ bhastrika pranayama (YBG) as compared to a physical exercise (PEG). The PEG also showed an
274
+ increase in PEFR and MVV, but the magnitude of change was less compared to YBG. These findings
275
+ are in line with earlier studies. However, the present study attempted to explore single bhastrika
276
+ pranayama effect on healthy individuals in comparison with physical exercise. The regular breathing
277
+ practices in yoga training[22] and Sudarshan Kriya[23] studies had reported significant improvement in
278
+ all PFTs such as FVC, FEV1, PEFR, and MVV. The current study also showed improvement in FVC
279
+ by 38.1% after 4 weeks’ practice of bhastrika. The finding is in consistent with the previous study that
280
+ has reported that pranayama training for 6-week improves ventilatory functions in the form of lowered
281
+ RR and by increasing FVC, FEV1, MVV, and PEFR.[9]
282
+ One of the previous studies conducted on bhastirka pranayama had showed significant improvement in
283
+ pulmonary function after 12 weeks of practice compared with baselines values. This study was limited
284
+ with no control group.[22] In addition to this, there are studies reporting improvements in pulmonary
285
+ 1, 28
286
+ 1, 28
287
+ function which investigated the effect of multiple pranayamas.[9,10,11] Whereas the current study
288
+ observed only the single pranayama (bhastrika) practice effect on pulmonary functions compared with
289
+ running.
290
+ FVC is an index of the state of elastic properties of the respiratory apparatus.[24] Whereas FEV1 is the
291
+ expelling rate of breath from the lungs in the 1 s. It reflects the flow-resistive properties to air flow in
292
+ airways that are >2 mm in diameter. FVC has been considered as a critical component of good health
293
+ and survival important for the evaluation of normal subjects and patients with respiratory and
294
+ cardiovascular conditions.[25] Kondam et al.[26] had reported that consistent practice of a variety of
295
+ asanas constantly recruits muscles of the thoracic cavity. This recruitment may lead to greater
296
+ musculature involvement and thereby result in improved FVC. Further, a study reported that yoga
297
+ exercises improve respiratory breathing capacity by increasing chest wall expansion and forced
298
+ expiratory lung volumes.[27] In both the studies, asanas were the intervention used, whereas in the
299
+ present study, asanas were not at all practiced by the participants, and only bhastrika pranayama was
300
+ intervened. Hence, improvement in the FVC and FEV1 could be due to recruitment and strengthening
301
+ of respiratory muscles that might have enhanced elastic properties of the lungs and chest, incidental to
302
+ the regular practice of bhastrika pranayama.[28] In contrast to this, there were no significant changes
303
+ observed in the above variables among PEG.
304
+ PEFR is a measure of elastic recoil pressure changes or the resistance of small airways.[24] In several
305
+ previous studies,[9,10,11,29] significant improvement in PEFR after yoga practice has been reported.
306
+ An improvement in PEFR was also observed in the present study, but in both YBG and PEG, where
307
+ YBG had a relatively greater magnitude of change [Table 1]. Although earlier PEFR was believed to be
308
+ effort dependent, now it is accepted to be effort independent and is mainly dependent on lung volume
309
+ and airway mechanics.[30] The “Bhastrika Pranayama” is one of the yogic well-regulated breathing
310
+ exercises that involves the use of lung spaces that are not used up in normal shallow breathing, thereby
311
+ it may increase the depth of breathing. Forceful or deep yogic breathing (pranayama) expands the
312
+ lungs more than normal breathing that may recruit previously closed alveoli, resulting in an increased
313
+ surface area of the respiratory membrane and air diffusion across the membrane.[31] The improved
314
+ breathing pattern may widen respiratory bronchioles, leading to effective perfusion of alveoli in a large
315
+ number.[32] Therefore, the increased PEFR in a higher magnitude of YBG than PEG might be a
316
+ consequence of the opening of a small airway in lungs and decrease in airway resistance.
317
+ MVV is respiratory apparatus measuring the status of respiratory muscles, i.e., mechanical properties
318
+ of lungs and chest, representing the flow-resistive properties of the system. MVV has a wide variability
319
+ with the subject and is an effort-dependent test.[24] In the present study, during bhastrika pranayama
320
+ practice, participants were asked and trained to inflate and deflate the lungs and chest to the fullest and
321
+ deepest possible extent as in previous pranayama studies.[9] Hence, the practice of bhastrika
322
+ pranayama in YBG may have helped to use diaphragmatic and abdominal muscles efficiently, leading
323
+ to significant increase in MVV in higher magnitude than PEG.[33]
324
+ In addition to this, regular inspiration and expiration during yoga and pranayama practices for a
325
+ prolonged period lead the lungs to inflate and deflate maximally that causes strengthening and
326
+ enhancement of endurance of the respiratory muscles.[8] And further, maximal lung inflation is the
327
+ major stimulus for releasing the lung surfactants[10] from the epithelial lining of alveoli and
328
+ prostaglandins into the alveolar spaces by the parenchyma of the lungs.[34] This may have increased
329
+ lung compliance and decreased bronchiolar smooth muscle tone, respectively. In other words,
330
+ decreased bronchiolar smooth muscle tone or increased bronchiolar smooth muscle relaxation may
331
+ increase the caliber of airways, leading to more airflow and less airway resistance. These all could be
332
+ the possible mechanism for increasing the pulmonary function in a higher magnitude of YBG
333
+ compared to PEG in the current study. Clinically, there are also few studies that have reported the
334
+ beneficial effects of yoga and breathing practices on respiratory disorders such as asthma[31,35,36] and
335
+ chronic obstructive pulmonary disease.[37,38]
336
+ This study assessed the direct effect of one particular breathing practice called bhastrika pranayama on
337
+ lung functions and compared it with physical exercise. An important thing to be noticed in this study
338
+ was that YBG had more significant effect than PEG. However, the study had the following limitations:
339
+ st
340
+ (i) latest version equipment was not used for measurement, so lung volumes such as functional residual
341
+ capacity and inspiratory capacity were not measured at rest and during exercise in the study; (ii)
342
+ intensity is a crucial part of training and it would have been ideal to strictly control this parameter by
343
+ monitoring energy expenditure while training sessions. As the study was comparing the effects of two
344
+ different streams of training; (iii) the sample size was small, and further studies with larger sample size
345
+ and longer duration can validate the findings with the underlying mechanism; (iv) combined practice of
346
+ yogic breathing and running as third group as well as control group as fourth added, would have been
347
+ more ideal; and (v) demographic details of all participants were self-reported. In addition, the present
348
+ study only recruited male participants; future studies can recruit both the genders in equal numbers for
349
+ generalization of outcome.
350
+ Conclusions
351
+ The results of the study conclude that the practice of bhastrika pranayama can recruit normally
352
+ unventilated lung spaces and help strengthen the respiratory muscles and increase the elastic properties
353
+ of lungs and chest, thereby improving its ventilatory functions.
354
+ It was interesting to find that there was a more significant increase in YBG than the PEG. Therefore,
355
+ yoga breathing, particularly bhastrika pranayama, may have a promising factor for those who partake
356
+ in aerobic-based sports (such as athletes, swimmers, and trekkers) and require efficient lungs to deliver
357
+ sufficient oxygen uptake.

14
+ Background: Studies have shown that conventional treatment methods with drugs, physiotherapy and exercises for common
15
+ neck pain (CNP) may be inadequate. Yoga techniques have been found to be effective complimentary therapies in chronic
16
+ low back pain and also for stress reduction in other diseases.
17
+ Objective: The aim of the study was to examine the complimentary role of a yogic relaxation called mind sound resonance
18
+ technique (MSRT) in non-surgical management of CNP.
19
+ Materials and Methods: In this randomized controlled study, 60 patients with CNP were assigned to two groups (yoga,
20
+ n=30) and (control, n=30). The yoga group received yogic MSRT for 20 minutes in supine position after the conventional
21
+ physiotherapy program for 30 minutes using pre-recorded audio CD and the control group had non-guided supine rest for 20
22
+ minutes (after physiotherapy), for 10 days. MSRT provides deep relaxation for both mind and body by introspective experience
23
+ of the sound resonance in the whole body while repeating the syllables A, U, M and Om and a long chant (Mahamrityunjaya
24
+ mantra) several times in a meaningful sequence. Both the groups had pre and post assessments using visual pain analog
25
+ scale, tenderness scoring key, neck disability score (NDS) questionnaire, goniometric measurement of cervical spinal flexibility,
26
+ and state and trait anxiety inventory-Y1 (STAI-Y1).
27
+ Results: Mann-Whitney U test showed significant difference between groups in pain (P<0.01), tenderness (P<0.01), neck
28
+ movements (P<0.01). NDS (P<0.01) and state anxiety (STAI-Y1) showed higher reduction in yoga (P<0.01) than that in the
29
+ control group. Wilcoxon’s test showed a significant improvement in both groups on all variables (P<0.01).
30
+ Conclusions: Yoga relaxation through MSRT adds significant complimentary benefits to conventional physiotherapy for CNP
31
+ by reducing pain, tenderness, disability and state anxiety and providing improved flexibility.

+ ABSTRACT
34
+ intROductiOn
35
+ Neck pain is one of the very common complaints across
36
+ the globe, with a prevalence of nearly 13%[1,2] and a lifetime
37
+ prevalence of nearly 50% and women are more prone than
38
+ men with an incidence ratio of 1.67 (women are more likely
39
+ than men to develop neck pain; incidence rate ratio=1.67,
40
+ 95% confidence interval 1.08-2.60).[3-5] Neck and shoulder
41
+ pain has also become an increasingly common health
42
+ complaint among adolescents, where the prevalence is found
43
+ to be higher in girls than in boys.[6] It is one of the frequent
44
+ causes for sickness absenteeism that could disrupt a nation’s
45
+ economy apart from disrupting the personal and professional
46
+ life of a victim.[7] Though the exact cause is unknown, altered
47
+ neck mechanics, advanced age-related changes, additional
48
+ load on the neck, occupational hazards as in computer
49
+ professionals or call center workers, faulty sleeping habits
50
+ and sudden violent jerking injuries to the neck as in whiplash
51
+ injury are some of the etiological factors.[8] “Common neck
52
+ pain” (CNP) which is not due to any organic lesion accounts
53
+ for more than 80% of neck pains.[9] Psychological stress
54
+ that may be associated in any of these factors cannot be
55
+ undermined.[10] Depression and anxiety are well-known
56
+ undesirable side effects of chronic neck pain.[11,12]
57
+ Since the underlying pathology of neck disorders remains
58
+ unclear, the treatments are aimed at relief of pain and
59
+ stiffness. The conventional conservative methods include
60
+ non-steroidal anti-inflammatory drugs, physical measures
61
+ such as heat, ultrasound, manipulation and exercises.[13]

65
+ Moffett et al, compared a brief physiotherapy intervention
66
+ on 268 patients (for 7 days) with usual physiotherapy
67
+ (for 14 days) for CNP and showed that latter may be only
68
+ marginally better than the former.[14]
69
+ Spray and stretch (vapo-coolant spray followed by passive
70
+ stretching) was compared to laser therapy and a placebo,
71
+ with no significant difference between the groups and
72
+ no significant reduction in pain.[15] A study conducted
73
+ to investigate the use of traction in two randomized
74
+ controlled trials revealed the difference between the groups
75
+ to be small and not significant.[16,17] Loy et al, showed that
76
+ symptomatic improvement was better with a combination
77
+ of cervical traction, short wave diathermy and electro
78
+ acupuncture, than a combination of TENS, collar, rest and
79
+ education in moderate quality neck pain.[18] With growing
80
+ dissatisfaction with these conventional therapies, there
81
+ is a pressing need for complementary measures and yoga
82
+ seems to hold promise through its multifaceted approach
83
+ to healing. Studies have established the role of yoga in
84
+ decreasing the pain and disability in chronic low back
85
+ pain, along with improved flexibility within 1 week to 4
86
+ months of yogic intervention with no adverse effects.[19]
87
+ Yoga has also been found to be an effective tool in reducing
88
+ stress levels.[20,21] Mind sound resonance technique
89
+ (MSRT) is one of the advanced guided yoga relaxation
90
+ techniques that can be practiced in supine or sitting
91
+ posture for achieving the goal of positive health, will
92
+ power, concentration and deep relaxation.
93
+ This tool [Table 1] was developed using the concepts from
94
+ traditional texts that talk about the power of Om (Mandukya
95
+ Upanishad) and Nadanusandhana (Hatha Yoga Pradipika)
96
+ for achieving internal mastery over the modifications of
97
+ the mind (Patanjali’s definition of yoga).[22] MSRT opens
98
+ up the secret of traditional chants called Mantras. MSRT
99
+ was one of the components of the intensive integrated yoga
100
+ program that was used as the intervention for low back
101
+ pain study.[23] Although MSRT has been used routinely as a
102
+ component of the integrated approach to yoga therapy for
103
+ treatment of neck pain and back pain at our yoga therapy
104
+ health home and the orthopedic center with encouraging
105
+ results, the results of these studies were not published.
106
+ Hence, this study was planned with an aim to evaluate
107
+ the efficacy of an add-on program of this yoga-based
108
+ relaxation technique and compare it with the conventional
109
+ physiotherapy technique. The hypothesis was that the yoga
110
+ group would show better improvement than the control
111
+ group in measures of pain, tenderness, disability, flexibility
112
+ and state anxiety.

114
+ The sample size was derived by calculating the effect
115
+ size based on the mean and standard deviation (SD) of
116
+ an earlier unpublished interventional study done at this
117
+ center using the same design for chronic low back pain,
118
+ by Anupritha et al.[23] Eighty-seven consecutive patients
119
+ who came to the Ebenezer’s orthopedic unit of Parimala
120
+ hospital, Bengaluru, India, for treatment of neck pain
121
+ were screened. Of these, 60 who needed physiotherapy
122
+ and consented to be in the study were randomized into
123
+ two groups of 30 each using a computer-generated random
124
+ number table on the “randomizer.com” software. There
125
+ were 28 females and 32 males.
126
+ The institutional ethical committee of SVYASA approved
127
+ the study. Signed informed consent was obtained from all
128
+ the participants.
129
+ Patients with CNP due to spasm (myalgia) or strain of
130
+ the neck muscles, ligament strain, cervical spondylosis
131
+ without any neurological impairment and who were
132
+ advised physiotherapy by the consulting orthopedic
133
+ surgeon were included in the study. It was ensured that
134
+ these were literate patients in the age group of 20–70 years
135
+ with no previous exposure to yoga.
136
+ Those with uncommon neck pains (UCNP) due to organic
137
+ causes such as congenital conditions like wry neck,
138
+ infective conditions like tuberculosis, inflammatory
139
+ conditions like rheumatoid arthritis, metabolic disorders
140
+ like osteoporosis, neoplastic conditions and post-traumatic
141
+ conditions with ligament or bone injuries were excluded.
142
+ The study design was as follows. This was a randomized
143
+ parallel two-armed control design. Sixty subjects who were
144
+ advised conventional treatment including physiotherapy
145
+ for CNP at the orthopedic centre were selected for the
146
+ study and were randomized into two groups after obtaining

+ the time. The scores for each of the forms range from 20
196
+ to 80, with high scores indicating presence of high levels
197

198
+ Data sheets marked by all patients for PAS, NDS and
199
+ STAI-Y1 were coded and kept aside for future assessment.
200
+ All measurements were taken before the intervention on
201
+ 1st day and 10th day.
202
+ intervention
203
+ Conventional schedule of physiotherapy that was
204
+ common to both the groups included (a) intermittent
205
+ cervical traction treatment (one-sixth of the body weight)
206
+ for 10 minutes, using the Cervical Traction instrument,
207
+ Electrocare (2001), Chennai, India (b) interferential
208
+ therapy for 10 minutes using IFT Technomed (2003) and
209
+ (c) ultrasound massage for 10 minutes using Ultrasound
210
+ Technomed 408 (2003).
211
+ An add-on intervention for the control group was a non-
212
+ guided supine rest for a period of 20 minutes after the
213
+ conservative treatment (physiotherapy) for 30 minutes.
214
+ Add-on yoga relaxation for the study group was used.
215
+ After the physiotherapy, the study group received the yoga
216
+ relaxation therapy called MSRT done in supine position.
217
+ MSRT is one of the advanced yoga techniques for achieving
218
+ deep relaxation. MSRT involves experiencing with closed
219
+ eyes the internal vibrations and resonance developed while
220
+ chanting the syllables A, U, M, Om and Mahamrityunjaya
221
+ mantra sounds.
222
+ Instructions were given in the recorded tape to feel the
223
+ quick relaxation technique, by way of a prerecorded audio
224
+ tape played with head phones for a period of 20 minutes,
225
+ after 30 minutes of conventional physiotherapy. Control
226
+ group had non-guided supine rest for 20 minutes after
227
+ the conventional physiotherapy. After randomization,
228
+ the pre-data on all variables were recorded. The role of
229
+ stress and the value of relaxation in general after the
230
+ conventional physiotherapy were explained to both the
231
+ groups by the research officer. The yoga group had a
232
+ separate session to explain the meaning and other details
233
+ of the intervention and was taught the technique through
234
+ personal instructions by the yoga therapist for half an hour
235
+ on the 1st day. From the second day onward, they were
236
+ asked to practice the same in supine position by listening
237
+ to the prerecorded audio tape on head phones in the annex
238
+ room of the physiotherapy department of the hospital.
239
+ The subjects in the control group were asked to relax
240
+ comfortably and calm down their mind in the supine rest
241
+ on their own in the annex room similar to the study group.
242
+ Post data were obtained on all subjects on the 10th day.
243
+ As this was an interventional study, there was no
244
+ possibility of blinding. The pain analog scale (PAS) sheets
245
+ and the answer sheets of State Trait Anxiety Inventory
246
+ (Form1) (STAI Y1) were kept aside for data extraction until
247
+ the completion of both pre and post data.
248
+ Assessments through the clinical examination by the
249
+ orthopedic surgeon before recruitment included (a)
250
+ history of all health problems followed by examination
251
+ for assessment of the degree and type of neck pain, (b)
252
+ neurological examination to look for any motor or sensory
253
+ deficit, (c) X-rays of the cervical spine in antero-posterior
254
+ and lateral views.
255
+ The primary outcome measures used were visual pain
256
+ analog scale (PAS), neck muscle tenderness, neck disability
257
+ score (NDS) and movements of the neck. The subjects
258
+ were asked to mark the degree of their present pain on
259
+ a numerical PAS by placing a dot on a 10-cm line drawn
260
+ on a white paper with centimeter markings, with 0 = “nil
261
+ pain” and 10 = “the worst possible pain the person can
262
+ imagine”.[24] Neck muscle tenderness grading of tenderness
263
+ was done using the following key: Grade 1 = tenderness on
264
+ deep palpation of para-cervical muscles, Grade 2 = patient
265
+ winces on pressure, Grade 3 = patient winces and withdraws
266
+ and Grade 4 = patient does not allow one to touch.[25] The
267
+ NDS developed by Vernon et al., was used.[26] It consists
268
+ of 60 questions related to pain intensity, personal care,
269
+ work, concentration, lifting, reading, driving, recreation,
270
+ headache and sleeping. The patients were asked to
271
+ complete the answers to these questions on a 6-point
272
+ scale ranging from 0 to 5. Cervical spinal flexibility was
273
+ measured by using a Lenthon Goniometer for the following
274
+ 21

276
+ resonance all over the body both during loud (Ahata: heard)
277
+ and mental chanting (Anahata: unheard). This is done
278
+ alternately starting from Ahata ‘
279
+ A
280
+ ’ followed by Anahata ‘
281
+ A
282
+
283
+ repeated three times. This is followed by similar repetitions
284
+ of all other chants. Resonance generated by MSRT helps in
285
+ revitalizing the internal energy in the body. It takes to deeper
286
+ layers of silence, wards off all fears and stresses. It can lead to
287
+ an experience of tremendous expansion and rest that forms
288
+ the basis of the healing power of these traditional chanting
289
+ called Mantras.[27] This type of mindfulness techniques that
290
+ involve deep levels of mind and body relaxation have the
291
+ ability to reduce the sympathetic nervous system activation
292
+ and increase parasympathetic nervous system activity and
293
+ restore homeostasis.
294
+ data extraction
295
+ Pain analog scale
296
+ The distance of the point marked by the patient on the
297
+ PAS line was measured by using a measuring scale and
298
+ expressed in centimeters.

300
+ The values for F
301
+ , E, RLF
302
+ , LLF
303
+ , RLR and LLR were expressed
304
+ in degrees.
305
+ Neck disability score
306
+ The total score was obtained by taking the sum of the
307
+ scores for all 60 questions.
308
+ state and trait anxiety inventory-y1
309
+ The scoring of the STAI-Y1 was carried out as per the
310
+ manual. The sum of the scores on the 5-point scale for the
311
+ 12 questions marked on the answer sheets was considered
312
+ as the total score for state anxiety.
313
+ data analysis
314
+ Data were analyzed using statistical package for social
315
+ sciences (SPSS, version 10.0). The base line values of
316
+ the two groups were checked for normal distribution by
317
+ using Shapiro-Wilk’s Test. Since the parameters were not
318
+ normally distributed, non-parametric tests were used.
319
+ Wilcoxon’s signed ranks test was done to compare the
320
+ means before and after intervention. The differences
321
+ between the two groups for all variables were assessed by
322
+ Mann-Whitney U test.

+ Results
326
+ [Table 2 shows results of both between and within groups]
327
+ Sixty subjects who satisfied the selection criteria were
328
+ registered for the study of which 32 (15 in control, 17 in
329
+ yoga) were females and 28 (15 in control, 13 in yoga) were
330
+ males. Table 3 shows the baseline characteristics which
331
+ were similar between groups. There were six dropouts
332
+ (two in yoga and four in control group). The reasons for
333
+ dropping out are mentioned in trial profile [Figure 1]. The
334
+ mean and SD of age in yoga group was 41.03 ± 15.54 and
335
+ that of control group was 42.23 ± 14.30 years. Duration
336
+ of neck pain was 6.8 + 3.16 and 5.40 + 2.66 years for
337
+ control group and yoga group, respectively. There was no
338
+ significant difference between groups for baseline values
339
+ on any of the variables. Table 4 shows the results within
340
+ the groups after 10th day of the intervention.

+ discussiOn
510
+ This prospective randomized control study was designed
511
+ to assess the efficacy of addition of a yoga-based relaxation
512
+ technique called MSRT to the conventional physiotherapy
513
+ program for 10 days in patients with CNP
514
+ . Analysis of
515
+ outcomes indicated significant difference between the
516
+ groups (Mann-Whitney test) and within groups (Wilcoxon’s
517
+ test) for all variables including PAS (P<0.01), tenderness
518
+ (P<0.01), flexion (P<0.01), extension (P<0.01), RLF
519
+ (P<0.01), LLF (P<0.01), RLR (P<0.01), LLR (P<0.01),
520
+ NDS (P<0.01) and state anxiety (STAI-Y1) of state and trait
521
+ anxiety inventory (P<0.01).
522
+ Meaning and comparison of a few earlier studies suggest
523
+ the usefulness of relaxation techniques in reduction of
524
+ pain and improvement of flexibility by reduction in muscle
525
+ tension in patients with chronic neck pain. Kabat–Zinn
526
+ showed that 65% of the patients felt lesser pain after
527
+ practicing mindfulness meditation for 10 weeks in patients
528
+ with chronic pain, who had not improved with traditional
529
+ medical care.[28] There are three randomized trial controls
530
+ on yoga for chronic low back pain. RCTs using Viniyoga
531
+ and Iyengar yoga therapy showed reduction in pain and
532
+ functional disability with non-significant changes in the

641
+ back pain by Tekur et al, a short-term intensive residential
642
+ yoga program was compared with intensive residential
643
+ physical exercise program.
644
+ The yoga group showed significantly better improvement
645
+ in pain-related disability and spinal flexibility.[19] There
646
+ is no study that has used MSRT for chronic pain. One
647
+ unpublished study at this institution (dissertation for
648
+ MSc degree of Shetty A., 2006) on the role of MSRT
649
+ in chronic low back pain showed reduction in back
650
+ pain, improvement in spine flexibility and decrease
651
+ in stress on using this relaxation technique. Sripada
652
+ Swamy and Vasudha in a dissertation for M.Sc., Yoga,
653
+ on Nādānusandāna have compiled information on the
654
+ practice of nādānusandhāna, benefits and its application
655
+ from ancient Indian scriptures as well as from the experts
656
+ in the field of yoga and spiritual lore.[29]
657
+ A review on the evidence for mind body therapies such
658
+ as guided relaxation, meditation, imagery and cognitive-
659
+ behavioral therapy in the treatment of pain-related medical
660
+ conditions concluded that these strategies may be an
661
+ appropriate adjunctive treatment for chronic neck and low
662
+ back pain as they offer better stress management techniques,
663
+ coping skills training and cognitive restructuring.[30]
664
+ As for the mechanism, a research conducted by Linton, to
665
+ review the psychological risk factors in back and neck pain
666
+ indicated a clear link between psychological variables with
667
+ neck and back pain. Results of the prospective studies showed
668
+ that the psychological variables were related to onset of pain,
669
+ acute, subacute and chronic pain. Stress, distress or anxiety
670
+ as well as mood and emotions, cognitive functioning and pain
671
+ behavior were found to be significant factors.[31]
672
+ As quoted in one study, tension that is associated with
673
+ stress is stored mainly in the neck muscles, diaphragm and
674
+ the nervous system. If these areas are relaxed, stress gets
675
+ reduced, minimizing the impact of stress on the individual.
676
+ It has also been suggested that the presence of depressive
677
+ symptoms predicts future musculoskeletal disorders but
678
+ not vice versa.[19] Stress can cause spasms by interfering
679
+ with co-ordination of different muscle groups involved in
680
+ the functioning of the neck.
681
+ Yoga is an ancient Indian science and way of life which
682
+ includes the practice of specific postures, regulated
683
+ breathing and meditation.[32] Yoga texts mention that the
684
+ root cause of many diseases can be traced to lifestyle and
685
+ amplified likes and dislikes at the mind level .The distressful
686
+ emotional surges (called aadhi)[33] may percolate into the
687
+ physical frame manifesting as diseases.[24] Hence, yoga is
688
+ fast advancing as an effective therapeutic tool in physical,
689
+ psychological and psychosomatic disorders.[34] In a study
690
+ by Vempati et al. on healthy adults, the yoga-based guided
691
+ relaxation was shown to reduce the sympathetic activity as
692
+ measured by autonomic parameters, oxygen consumption
693
+ and breath volume.[21] Medical and pre-medical students
694
+ showed lesser anxiety and stress during an examination
695
+ period after 8 weeks of meditation.[35] Transcendental
696
+ meditation (TM) was compared to muscle relaxation in its
697
+ effectiveness in controlling stress with significantly better
698
+ reduction in blood pressure in the TM group.
699
+ Brain imaging studies have shown that meditation shifts
700
+ the brain activity in the prefrontal cortex from the right
701
+ hemisphere to the left indicating that the brain is re-
702
+ oriented from a stressful fight or flight mode to one of
703
+ acceptance, a shift that may indicate better contentment.[29]
704
+ Thus, the etiology of CNP being multifactorial, there is
705
+ sufficient evidence in the literature to demonstrate a
706
+ requirement to draw treatment options from many sources
707
+ in order to achieve a favorable pain relief outcome.
708
+ The RCT design demonstrated several methodological
709
+ strengths: (a) CNP of both the categories, physical
710
+ (cervical spondylosis) and psychological (muscle spasm)
711
+ International Journal of Yoga  Vol. 3  Jan-Jun-2010
712
+ 24
713
+ were included in the study; (b) it used a standardized
714
+ randomization procedure; (c) there was baseline matching
715
+ of confounding factors such as age, sex, height, weight
716
+ and BMI; (d) assessment was multidimensional including
717
+ both objective and subjective parameters; (e) because
718
+ the duration of the yoga intervention was short, the
719
+ acceptability and adherence to the therapy was good;
720
+ (f) As MSRT was played using a cassette in the therapy
721
+ sessions, it could be reproduced in the exact way for all
722
+ cases.
723
+ cOnclusiOn
724
+ This randomized control study has shown that yoga
725
+ relaxation through MSRT adds significant complimentary
726
+ benefits to conventional physiotherapy for CNP by
727
+ reducing pain, disability and state anxiety and improving
728
+ flexibility.
729
+ limitations of the study
730
+ This was a study from one orthopedic unit in Bengaluru
731
+ city only. The MSRT technique used involved chanting of
732
+ Indian mantra which may be unacceptable and difficult
733
+ for non-Indian community. Follow up of these cases are
734
+ required for compliance and recurrences.
735
+ suggestions for future Work
736
+ Future studies should be done in other study groups from
737
+ different orthopedic centers in India and other countries
738
+ to establish the generalizability. In addition, there is a
739
+ need for clinical studies to determine whether yoga-based
740
+ relaxation technique can decrease medication requirement.
741
+ Basic physiological studies to understand the mechanisms
742
+ responsible for therapeutic effects of MSRT on CNP may
743
+ be undertaken.
744
+ implications and recommendations
745
+ An integrative holistic model incorporating psychological
746
+ and physical therapies for CNP will strengthen the
747
+ rationalistic approach to treatment of CNP
748
+ . We recommend
749
+ that this simple procedure of using relaxation during
750
+ and after the physiotherapy may be incorporated in
751
+ all conventional therapy units round the globe in the
752
+ management of CNP
753
+ .

+ A number of studies conducted in India  have shown that
29
+ yoga practice improves weight, blood pressure, insulin,
30
+ triglycerides,[3] blood pressure,[4,5] FBS and PPBS levels,[6,7]
31
+ pulse rate.[5] In most of the above studies the period of
32
+ yoga intervention was anywhere between 40  days to
33
+ a maximum of 90 days to observe the desired effects.
34
+ The yoga intervention also differed from Hatha yoga to
35
+ Yoga nidra. The fact that in our study we have observed
36
+ changes in all outcome variables after 2 weeks of in‑patient
37
+ stay shows that the IAYT is effective in the treatment of
38
+ diabetes ‑ where all the components of the IAYT model are
39
+ integrated and provided to have a desired effect on each of
40
+ the five levels of existence in a controlled and monitored
41
+ environment ‑ asanas and pranayama comprise only a
42
+ minuscule part of the entire program. In this context, in
43
+ most of the above research studies, yoga was possibly
44
+ equivalent to “asana, pranayama and/or meditation
45
+ practice.” Hardly any studies mentioned controlling for
46
+ extraneous factors which could have status played an
47
+ integral role in the effectiveness of the program (diet, stress
48
+ and medication compliance).
49
+ The challenge would be to replicate this holistic
50
+ model of IAYT for diabetes actively in community and
51
+ out‑patient settings, as it would require controlling for
52
+ medication compliance, adherence to yoga and stress
53
+ in a nonresidential set‑up. A  three‑arm randomized
54
+ controlled study with:  (1) In‑patient IAYT model,
55
+ (2) out‑patient IAYT model and (3) control group could
56
+ be an important and interesting step in understanding
57
+ the factors determining effectiveness and replicability of
58
+ the IAYT model in the Indian community setting, which
59
+ in turn would help reduce the overall burden of diabetes
60
+ in Indian community.

64
+ Sir,
65
+ In continuation to the article published in your esteemed
66
+ journal titled, “Decoding the integrated approach to
67
+ yoga therapy: Qualitative evidence based conceptual
68
+ framework” by Villacres et al.,[1] we would like to add
69
+ supportive quantitative data to understand and explain
70
+ the mechanism of the integrated approach to yoga
71
+ therapy (IAYT) model developed by Swami Vivekananda
72
+ Yoga Anusandhana Samasthana (SVYASA),[2] based on
73
+ the Pancha Kosa concept. As mentioned by Villacres
74
+ et al.,[1] the IAYT can be understood as a holistic model,
75
+ which corrects the imbalances at physical, mental
76
+ and emotional levels through application of multiple
77
+ components such as asanas, diet, loosening exercise,
78
+ breathing exercises, pranayama, cyclic medication, mind
79
+ sound resonance technique, devotional sessions and yogic
80
+ counselling (lectures). Rightly as the author put it, “no
81
+ component singularly can claim to be the IAYT, nor could
82
+ possibly have the same effects as the whole model,”[1]
83
+ A look at retrospective quantitative data of 560 patients
84
+ with diabetes (who presented to primary treatment
85
+ center – Arogyadhama, Prashanti, SVYASA, Jigani between
86
+ 2008 and 2010) who underwent the IAYT helps us
87
+ further understand the workings of this model. The
88
+ patients stayed for a minimum of 6 days to a maximum of
89
+ 15 days (mean [standard deviation] duration of in‑patient
90
+ stay: 12.38  [6.10] days), during which the IAYT for
91
+ diabetes was imparted to them. The four important factors
92
+ that could affect their diabetes status:  (1) Medication
93
+ compliance, (2) diet, (3), stress and (4) adherence to yoga,
94
+ were monitored and controlled. Medication compliance
95
+ and adherence to yoga was controlled by the medical
96
+ doctor and yoga therapist in‑charge in the section; diet was
97
+ controlled as standard saatvik food is usually provided at
98
+ Prashanti, SVYASA to all patients admitted; the ambience
99
+ of Prashanti campus (away from city life, silence and
100
+ amidst nature) could be considered as a calming factor
101
+ to combat stress. Assessment and analysis of diabetes
102
+ related parameters in the above mentioned controlled
103
+ environment showed that though the baseline values of
104
+ all variables were not normally distributed (P < 0.01),
105
+ nonparametric test analysis of pair wise time effect using
106
+ the Wilcoxon signed ranks test showed a significant
107
+ improvement in respiratory rate, pulse rate, systolic
108
+ blood pressure, diastolic blood pressure, weight, breath
109
+ holding rate, fasting blood sugar (FBS), and postprandial
110
+ blood sugar  (PPBS) from before yoga to after yoga
111
+ practice [P < 0.001, Table 1].

31
+ An earlier developed yoga program for caregivers of schizophrenia was remodeled into an audio-visual self-help manual in three languages
32
+ and validated by mental health and yoga experts. 48 consenting primary family caregivers of outpatients with schizophrenia were screened,
33
+ recruited, and allotted randomly to Yoga or Care as Usual Group. Participants in Yoga group were taught yoga from the self-help manual (1
34
+ session of 1 h every month for 5 months). The caregivers were asked to follow the manual for the remaining month at home. Assessments of
35
+ burden, perceived stress, quality of life, and anxiety-depression were conducted by a rater blind to the group status at baseline and at the end
36
+ of every month.
37
+ Results:
38
+ Post factoring for missing data, Repeatedmeasure ANOVA was conducted; which showed that there was no significant difference between
39
+ the group that practiced the selfhelp yoga manual and the care as usual group. The caregivers who practiced yoga at home maintained an
40
+ average of 50% attendance and “very well” level of yoga performance.
41
+ Conclusion:
42
+ The audio-visual self-help yoga manual was found to be feasible to use by the caregivers even though its effectiveness could not be

45
+ Introduction
46
+ In India, majority of the family caregivers take on the burden of caring for their relative with schizophrenia at their home in the community.
47
+ Due to the stressful demands of caring, they often experience significant burden[1] and sometimes border close to clinical depression. Yoga
48
+ has been found to be effective in the management of stress.[2] Further yoga, which originated in India, is seen to be a more practical
49
+ intervention for caregivers to practice in the community.
50
+ Jagannathan et al.,[3] in a randomized controlled study provided caregivers of in-patients with schizophrenia yoga intervention. It was
51
+ noticed that irrespective of the intervention, with reduction in patient symptoms, the burden of the caregivers also reduced. Further, the yoga
52
+ intervention given was provided only for a period of 7 days, which experts in the field of yoga believed to be insufficient. Varambally et al.
53
+ [4] in another controlled study found that caregivers of outpatients with psychosis were able to learn and retain yoga practices for a period
54
+ of 1 month, leading to reduced burden and improved quality of life. However, a large proportion of caregivers were unable to enroll and
55
+ adhere to the study protocol due to inability to attend yoga sessions at centers far away from their community.
56
+ Based on the results of the above two studies, the current study was designed, with the aim of testing the feasibility of a self-help audio-
57
+ visual yoga manual on burden of Indian caregivers of persons with schizophrenia, living in the community. The researchers believe that this
58
+ self-help audio-visual yoga manual would be a novel and viable option to encourage caregivers to adopt yoga at their homes in the
59
+ community.
60
+ Methods
61
+ This study was funded by the Indian Council of Medical Research, New Delhi, India. It was reviewed and approved by the Institute Ethics
62
+ Committee, at National Institute of Mental Health and Neurosciences, Bengaluru. Written informed consent was obtained from the mental
63
+ health professionals and yoga therapist who helped in the remodeling of the self-help manual and family caregivers who participated in the
64
+ feasibility study.
65
+ The research was conducted in three phases. In Phase I, the earlier developed and validated yoga program for caregivers of schizophrenia[5]
66
+ was remodeled into a self-help written manual with an audio-visual digital versatile disc (DVD). In Phase II, this redeveloped and validated
67
+ self-help manual was tested for its feasibility on five caregivers of outpatients with schizophrenia. In Phase III, the self-help yoga manual
68
+ was tested for its effectiveness on burden of Indian caregivers of persons with schizophrenia, living in the community.
69
+ Phase 1 – Redevelopment and validation of self-help manual
70
+ The earlier developed and validated yoga program for caregivers of schizophrenia[5] was successfully remodeled into a self-help manual
71
+ and DVD and validated (Face and content). The job of developing the self-help yoga manual and DVD was outsourced to a private vendor
72
+ outside the institute. The videoshooting for the DVD took place at S-VYASA campus. S-VYASA provided technical expertise as well as a
73
+ trained yoga therapist as a model for the whole shooting. The entire process, i.e., video and photo shoot of the yoga procedures and editing
74
+ of the video was monitored and supervised by (Co-I) and his team from S-VYASA. Parallel to video shooting, the manual was developed as
75
+ a self-help format and translated into Kannada and Hindi Languages by respective language translators. Both the language translations
76
+ content were edited and validated by the yoga experts (n = 7). Once the video editing and content of the manual in all three languages were
77
+ finalized and validated by the experts, the voice over to the video was initiated using the content of respective language's manual. The final
78
+ draft of the video with voice over and manual in all three languages was presented to all coinvestigators of the study as well as to the experts
79
+ from S-VYASA for their feedback. After 2–3 iterations, the manual and DVD was approved. The final manual and DVD was in English,
80
+ Kannada, and Hindi languages, with an aim to help reach out to a large section of caregivers living in rural/semi-urban/urban India.
81
+ Phase 2 – Feasibility Testing of the manual
82
+ Primary caregivers of outpatients diagnosed with schizophrenia (according to ICD 10, F20, F25, and F29) with a minimum of 3 months
83
+ duration of illness, with a Clinical Global Inventory–Severity Scale[6] score of 4 and below, between 18 and 60 years of age, who continued
84
+ to care for the patient even after discharge from the hospital, who were willing to participate weekly once in a yoga training for a period of 1
85
+ month, who knew Kannada, English, or Hindi languages and were ready to provide consent to participate in the study were recruited.
86
+ Participants were excluded if the caregivers were diagnosed with severe psychiatric or neurological disorders. Caregivers also were
87
+ excluded if they had another relative with psychiatric or neurological illness and/or if their patient relapsed with psychiatric symptoms
88
+ during the course of the study. Caregivers who have undergone formal yoga training (certificate course from a recognized institute) and who
89
+ were practicing yoga regularly for the past 1 month or who had undergone yoga training program from SVYASA University were not
90
+ included in the study.
91
+ This redeveloped and validated self-help manual was tested for its feasibility on five caregivers of outpatients with schizophrenia for the
92
+ period of 1 month. The five caregivers were taught the yoga practices by a trained yoga therapist, from the self-help manual in three parts (1
93
+ session of 1 h every week for 3 weeks) during their weekly follow-up visits followed by the fourth session inclusive of all three parts as a
94
+ concluding session. The caregivers were asked to follow the manual and practice the exercises taught to them for the remaining days till the
95
+ next follow-up date. The yoga therapist maintained a log of the caregiver's practice schedule and attendance at home to check their
96
+ adherence. The yoga instructor also recorded the performance of caregivers at each follow-up visit.
97
+ At every weekly follow-up Burden, (Burden Assessment Schedule),[7,8,9,10,11,12,13,14,15,16,17] Quality of Life (WHO Quality of Life–
98
+ Brief Questionnaire),[7] Stress using (Perceived Stress Scale [PSS])[8] and Anxiety and depression (Hospital Anxiety and Depression Scale
99
+ [HADS])[9] was assessed. All the assessment tools were administered by a Research Scientist 1 (RS1) in the local language (Kannada or
100
+ Hindi) for the benefit of clients who spoke and understood only the vernacular language. A feedback form to assess the Program, Handouts
101
+ (Yoga Manual and Video), and Trainer (a mix of qualitative and quantitative data) was taken during the time the first, second, and third
102
+ assessments were conducted.
103
+ Data were analyzed using the Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, Version 24.0. Armonk, NY:
104
+ IBM Corp). The sociodemographic data were analyzed using descriptive statistics, the results were analyzed using nonparametric statistics
105
+ (Friedman's Chi-square test) and the qualitative feedback was content analyzed.
106
+ Phase 3 –- Testing for effectiveness
107
+ To test the effectiveness of the self-help yoga manual, a directional hypothesis was adopted: (H1): Self-help yoga manual (Y) independently
108
+ enables caregivers of outpatients with schizophrenia to reduce burden of caregiving than caregivers who are not provided any yoga manual
109
+ (Care as Usual; CAU) (YT > CAU).
110
+ To achieve a target sample of 60 (30 in each group: Yoga Therapy – YT and Care As Usual – CAU), a sample of 1040 participants were
111
+ screened with predefined inclusion and exclusion criteria, as mentioned in Phase 2. The caregivers who met the inclusion and exclusion
112
+ criteria were screened using the Self-Reporting Questionnaire[10] and whoever scored 8 and below (having no mental health problems)
113
+ were offered to participate in the study. The CONSORT diagram detailing the process of screening is given in Figure 1
114
+ Open in a separate window
115
+ Figure 1
116
+ Consort diagram depicting the detailed process of screening
117
+ This study used a two-group single-blind, randomized control design. RS1 explained the content of the consent and study process to the
118
+ participants, including the randomization process. Whoever accepted and agreed to participate in the study by signing the written consent,
119
+ were recruited into the study and their sociodemographic details were procured along with baseline assessments by RS1, who was blind to
120
+ the randomization status. To maintain rater blinding, assessment was conducted by RS1 and group allocation status was managed by
121
+ Research Staff 2 (RS2) (yoga therapist), and this was done in two separate places. The randomization was made in opaque sealed envelopes
122
+ by the principal investigator and managed by RS2. Once the baseline assessments were completed, the participants were sent to yoga center
123
+ to meet RS2 for the randomized allotment. For each patient, RS2 opened one opaque-sealed envelope having the group allocation. He was
124
+ thus unaware of the group status of the next recruited patient (allocation concealment). RS2 would tear the group allocation envelope in
125
+ front of the participant and let them know in which group they were allotted, i.e., YT or CAU.
126
+ Participants who were allotted to Yoga group (YT) were taught the yoga exercises from the self-help manual in three parts (1 session of 1 h
127
+ every month for 3 months) during their monthly follow-up visits. The manual contained step-wise details of the yoga asanas/pranayama
128
+ along with pictures for ease of practice. Further, a DVD of the yoga practices was attached to the written manual to help the caregivers to
129
+ follow the practices through audio-visual medium. The caregivers were asked to follow the manual and practice the exercises taught to them
130
+ for the remaining month till the next follow-up date.
131
+ Participants who were allotted to waitlist control group (CAU) did not receive yoga training. Instead, they were available for assessments
132
+ for the 5-month period and were called for follow-up to the outpatient Department once in a month. Normal consultation time spent with the
133
+ caregiver/patient at the initial contact was 3 h. The caregivers in this group (CAU) were however taught the yoga exercises from the self-
134
+ help manual in three parts (1 session of 1 h every month for three months) during their monthly follow-up visits only postcompletion of the
135
+ data collection timelines (after completion of their day 150 assessments).
136
+ At every monthly follow-up, Burden, (Burden Assessment Schedule),[6] Quality of Life (WHO Quality of Life–Brief Questionnaire),[7]
137
+ Stress using (PSS),[8] and Anxiety and depression (HADS)[9] along with yoga performance was assessed.
138
+ Data were analyzed using the Statistical Package for the Social Sciences (SPSS, Version: IBM-SPSS 24). The socio-demographic data were
139
+ analyzed using descriptive statistics, and the results were analyzed using parametric statistics (Repeatedmeasure ANOVA [RMANOVA]) as
140
+ the data was normally distributed. Missing data analysis was also conducted.
141
+ Results
142
+ Phase I
143
+ Theme 1: What caregivers I valued in the program
144
+ Theme 2: Suggestions to improve the programme
145
+ Theme 3: Caregiver's overall experience of the programme
146
+ The manual contained step-wise details of the yoga asanas/pranayama along with pictures for ease of practice. The audio-visual format of
147
+ the yoga practices was added to the written manual to help the caregivers to follow the practices through audio-visual medium. The entire
148
+ yoga program consisted of Yoga practices and Satsang (Philosophy of Yoga) which was broken down into three parts (The final manual is
149
+ can be obtained from the authors on request).
150
+ Phase II
151
+ Five caregivers gave their consent for the feasibility study and all of them completed the 4 weeks follow-up assessments except the 5
152
+ person who missed the last follow-up. Although all the outcome variables were normally distributed at baseline, as the sample size was
153
+ small (n = 5), nonparametric tests were used to analyze the data. The results of Friedman Chi-square test across the timelines showed
154
+ significant improvement in burden and stress scores of the caregivers over the period of 4 weeks. All the caregivers were able to follow-up
155
+ the instructions given and practices taught by the yoga therapist and were practicing the same in their houses regularly, i.e., average of 20
156
+ days in a given month.
157
+ The caregivers provided feedback that the overall pace and length of program was neutral to excellent with scores ranging from 3 to 5. With
158
+ respect to usefulness and ease of understanding the video and manual, rating ranged between Excellent and Good, with scores of 4–5.
159
+ Overall rating of trainer was Good–Excellent with scores ranging between 4 and 5. The qualitative feedback supported the quantitative
160
+ Likert ratings and could be divided into three broad themes with supporting quotes of the caregivers:
161
+ ”It is short, easy to learn and good” (C1, 26 years, female)
162
+ Suryanamaskara and other exercises were good” (C4, 27 years, female)
163
+ ”I liked the way the yoga teacher taught and explained the details of the practices” (C5, 42 years, female).
164
+ ”The contact sessions can be conducted at different locations in Bangalore if possible” (C1, 26 years, female)
165
+ ”Group session rather individual would be better” (C3, 20 years, male)
166
+ ”Want little more information of the practices if possible” (C4, 27 years, female).
167
+ It is a very good initiative with easy and effective yoga techniques (C1, 26 years, female)
168
+ ”It helped relieve stress and tension and made me feel healthy to take care of my patient” (C2, 55 male)
169

170
+ ”I felt calm–peace of mind and had relief” (C3, 20 years, male)
171
+ ”This programme is very good. It totally relaxed me gave me more peace of mind” (C5, 42 years, female).
172
+ Phase III
173
+ A total of 48 samples were recruited into the study, i.e., 23 in yoga group and 25 in care as usual (control) group. There were different
174
+ strategies used, to track, contact. and inform recruited caregivers to come for regular follow-ups. Even after regular follow-up calls, sending
175
+ postal reminders, checking the recruited caregiver's patient file once in month at medical record section, the follow-up rates were poor [
176
+ Figure 1]. The sociodemographic details of the caregivers in Yoga and CAU group are detailed in Table 1.

+ Shapiro–Wilk normality test was conducted for both the group's, for all the four variables at baseline. Burden Assessment Scale, PSS, and

234
+ differences between the groups across all the outcome variables.
235
+ Due to high rates of dropouts over the study timelines, it was decided to do missing data analysis, where the mean scores of the latest
236
+ follow-up that the client attended was considered as the data for the subsequent follow-ups that he/she missed. Using this method of missing
237
+ data analysis, further statistical analysis was conducted.
238
+ RMANOVA, a parametric test to find the interaction effect over the period of 6 months, was performed for BAS, WHO-QOL-Brief, and
239
+ PSS. From Table 2, it can be observed that there is no significant difference between those who practiced the self-help yoga manual and
240
+ those who received care as usual in either of the outcome variables. To understand the effect of the intervention in the two groups on HADS
241
+ (data not normally distributed) over a period of time, Friedman Chi-square, a nonparametric test was performed. From Table 3, it can be
242
+ observed that there is no significant difference in the outcome of HADS between those who were doing yoga and those who got care as
243
+ usual, indicating that both the interventions had an equal effect.

405

408
+ Discussion
409
+ The goal of the study was to help reduce the burden and stress of the caregivers of persons with schizophrenia by training them to self-
410
+ practice yoga in their homes. This was done essentially to help reach yoga to the community and for reducing the logistic barriers to
411
+ attending and practicing yoga in a tertiary care center.[11] The qualitative and quantitative results of the feasibility testing phase of the study
412
+ depict that the audio-visual self-help yoga manual for Indian caregivers of persons with schizophrenia is feasible to practice, helps reduce
413
+ stress and burden of the caregivers (objectively and subjectively), and can be tested for its efficacy in the future.

420
+ The effectiveness of the self-help manual could not be established as no significant difference was observed between those who practiced
421
+ the self-help yoga manual and those who received care as usual in any of the outcome variables. These results need to be interpreted in the
422
+ background of poor follow-rates (high attrition) which was as low as 35% at the end of 1 -month follow-up and which dropped further to
423
+ 14% follow rate. The reasons for dropout (barriers to yoga) as expressed by the caregivers included loss of work day, long distance of travel
424
+ from their homes, no alternative caregiver to take care of patient, patient getting symptomatically better, and hence caregivers not
425
+ experiencing burden nor feeling the need for yoga. Most yoga studies depict a yoga adherence rate of 50%[12] in a community setting. As
426
+ there was hardly any data to analyze at the end of the 6 -month follow-up, it would be false to interpret that the self-help manual was not
427
+ more effective than the care as usual group. Both the Pilot Phase and the main study results depicted significant reduction in burden and
428
+ stress scores at the end of 1 month in those who practiced the self-help manual for the period of the 1 month. If attrition rates in yoga studies
429
+ can be controlled, the true effectiveness of yoga intervention could be depicted.
430
+ Caregivers seemed to be more motivated to attend sessions in the feasibility phase, once week sessions, as compared to the Main study
431
+ phase, sessions conducted once a month. Thus, a more regular follow-up may be required to maintain follow-rates and adherence to yoga.
432
+ Even if our study with a longer training period (of 5 months) had shown effectiveness, its wider application in routine clinical practice
433
+ would have been a daunting task as only a minuscule proportion of caregivers were able to go through longer periods of training. There are
434
+ many barriers to convince people to travel long distances from their homes to a center for yoga therapy[11] once they are discharged. In this
435
+ context, we believe that possible the yoga training programs should be developed for not more than a period of 1 month to help reduce
436
+ attrition rates. Traditional yoga therapists may argue that a 1 month program could be too short to perceive any effects of yoga.
437
+ Studies have time and again discussed the importance of the length of yoga practice[13,14,15,16] to observe desirable effects. Caregivers
438
+ who reported that they had practiced yoga, did they practice yogasana at home as well as they did under supervision? This is indeed a
439
+ genuine concern. Given the long duration of illness, there could well be certain degree of cynicism and lack of interest in the caregivers. The
440
+ seriousness with which they would have adhered to any interventions is doubtful. This observation in vindicated by the fact that <50% of
441
+ the caregivers in the yoga group reported practicing yoga daily.
442
+ Scales used may not have been sensitive in tapping the efficacy of the interventions. The burden scales provide a total burden score which
443
+ encompasses all components of burden including financial, occupation, family routine, family leisure, family interaction, social relations,
444
+ and emotional–physical–mental health. Yoga therapy may not necessarily have a bearing on all these components of burden and stress.
445
+ Although we realized this limitation in the beginning of this study itself, we still decided to use these scales because: (1) they were widely
446
+ used scales which had no good alternatives and (2) they were clinically meaningful outcomes and we had hypothesized that the
447
+ interventions would ultimately lead to a reduction in burden through different methodologies (e.g.,: through developing a sense of
448
+ equanimity by practicing yoga; understanding patient behavior using the skills taught in the psychosocial program). Thus, instead of
449
+ discounting the effectiveness of the program, any negative result could be viewed as a possible inability of the structured instruments to tap
450
+ the effectiveness of the program in reducing the burden of the caregivers.
451
+ st
452
+ th
453
+ Expectation of the caregivers was to “cure the patient.” Hence, caregivers found it difficult to relate their participation in the yoga
454
+ intervention. Further as most of the caregivers did not consider the caretaking process to be burdensome or stressful (they considered it as
455
+ their family responsibility), interventions could have been effective for those caregivers who expressed a felt need for these interventions.
456
+ Resilience of Indian caregivers could be higher than reported in the Western studies. A reason for this is the strong family system present in
457
+ the country which helps the patient and caregivers cope with the illness effectively. By providing interventions to all caregivers, we may be
458
+ falsely assuming that they all equally burdened by the caretaking process and have poor resilience.
459
+ This is one of the first studies in India to have systematically tested the feasibility and effectiveness of audio-visual self-help yoga manual
460
+ for Indian caregivers of persons with schizophrenia. The self-help yoga manual developed in this study was observed to be feasible to use
461
+ by the caregivers qualitatively and quantitatively in reduction of their burden. This manual can thus be provided to caregivers of persons
462
+ with schizophrenia in the community and can also act as a guide for mental health professionals and yoga therapists in the future. The
463
+ effectiveness of this manual however could not be conclusive arrived at, due to the poor follow rates (high attrition). In this background, it
464
+ would be false to interpret that the self-help manual was not more effective than the Care as usual group, as in the Feasibility Phase, time
465
+ effect results depicted significant reduction in burden and stress scores at the end of 1 month in those who practiced the self-help manual for
466
+ the period of the 1 month. If attrition rates in yoga studies can be controlled, the true effectiveness of yoga intervention could be depicted. In
467
+ this context, we believe that future yoga research should provide yoga training for not more than a period of 1 month to help reduce attrition
468
+ rates. Also as attrition was mainly because of the inability of caregivers to travel to a tertiary care center for yoga training, testing the
469
+ feasibility and effectiveness of virtual yoga sessions should be the next research questions that should be addressed by yoga researchers.
470
+ Conclusion
471
+ The self-help audio-visual yoga manual was found to be feasible to use by the caregivers even though its effectiveness could not be
472
+ ascertained due to high attrition.

+ Abstract
41
+
42
+ Context and Aim: Complementary and alternative therapies
43
+ (CAM) are gaining popularity amongst patients as add on to
44
+ conventional medicine. Yoga stands third amongst all CAM
45
+ that is being used by cancer patients today. Different
46
+ schools of yoga use different sets of practices, with some
47
+ using a more physical approach and many using meditation
48
+ and/or breathing. All these modules are developed based on
49
+ the needs of the patient. This paper is an attempt to provide
50
+ the basis for a comprehensive need based integrative yoga
51
+ module for cancer patients at different stages of treatment
52
+ and follow up. In this paper, the holistic modules of the
53
+ integrated approach of yoga therapy for cancer (IAYTC)
54
+ have been developed based on the patient needs, as per the
55
+ observations by the clinicians and the caregivers. Authors
56
+ have attempted to systematically create holistic modules of
57
+ IAYTC for various stages of the disease and treatment.
58
+ These modules have been used in randomized trials to
59
+ evaluate its efficacy and have shown to be effective as add-
60
+ on to conventional management of cancer. Thus, the
61
+ objective of this effort was to present the theoretical basis
62
+ and validate the need based holistic yoga modules for
63
+ cancer patients.
64
+ Materials and Methods: Literature from traditional texts
65
+ including Vedas, Ayurveda, Upanishads, Bhagavat Gita,
66
+ Yoga Vasishtha etc. and their commentaries were looked
67
+ into for references of cancer and therapeutic directives.
68
+ Present day scientific literature was also explored with
69
+ regards to defining cancer, its etiopathology and its
70
+ management. Results of studies done using CAM therapies
71
+ were also looked at, for salient findings. Focused group
72
+ discussions (FGD) amongst researchers, experienced gurus,
73
+ and medical professionals involved in research and clinical
74
+ cancer practice were carried out with the objectives of
75
+ determining needs of the patient and yoga practices that
76
+ could prove efficient. A list of needs at different stages of
77
+ conventional
78
+ therapies
79
+ (surgery,
80
+ chemotherapy
81
+ and
82
+ radiation therapy) was listed and yoga modules were
83
+ developed accordingly. Considering the needs, expected
84
+ side effects, the energy levels and the psychological states
85
+ of the participants, eight modules evolved.
86
+ Results: The results of the six steps for developing the
87
+ validated module are reported. Step 1: Literature review
88
+ from
89
+ traditional
90
+ yoga
91
+ and
92
+ ayurveda
93
+ texts
94
+ on
95
+ etiopathogenesis and management of cancer (arbuda), and
96
+ Amritanshu Ram, Nagarathna Raghuram, Raghavendra M. Rao et al.
97
+
98
+ 270
99
+ the recent literature on cancer stem cells and immunology
100
+ of cancer. Step 2: Focused group discussions and
101
+ deliberations to compile the needs of patients based on the
102
+ expected side effects, energy levels and the psychological
103
+ state of the patient as observed by the caregivers and the
104
+ clinicians. Step 3: Content validation through consensus by
105
+ the experts for the eight modules of IAYTC that could be
106
+ used as complimentary to conventional management of
107
+ cancer at different stages during and after the diagnosis was
108
+ created. Step 4: Field testing for safety and feasibility of the
109
+ modules through pilot studies. Step 5: Compilation of the
110
+ results of efficacy trials through RCTs and step 6: A review
111
+ of our studies on mechanisms to offer evidence for action
112
+ of IAYTC on psycho-neuro-immunological pathways in
113
+ cancer.
114
+ Conclusion: The evidence from the traditional knowledge
115
+ and recent scientific studies validates eight modules of
116
+ integrated approach of yoga therapy for cancer that can be
117
+ used safely and effectively as complimentary during all
118
+ conventional cancer therapies.

+ Introduction
125
+
126
+ Cancer is a leading cause of death worldwide. [1]
127
+ Research to eradicate the tumor burden without
128
+ harming the host has progressed with many success
129
+ stories that have resulted in cure (in a few cancers),
130
+ improved longevity and quality life. In spite of these
131
+ advances, it is intriguing that the prevalence of the
132
+ disease has not reduced. The world statistics indicates
133
+ that in India alone, 22.2% of women presently suffer
134
+ from cancer which is expected to increase to almost
135
+ 30% in the next five years. [2] This has led patients to
136
+ resort to complementary and alternative medicine
137
+ (CAM).
138
+ According
139
+ to
140
+ a
141
+ previous
142
+ survey,
143
+ approximately 21% of cancer survivors in the United
144
+ States had engaged in CAM practices. [3] Among
145
+ these, yoga was the third most commonly accepted
146
+ therapy [3].
147
+ Malignant tumors are known to consist of a stem
148
+ cell population that exhibits both the tumor markers
149
+ and the stem cell markers. Thus these are called
150
+ cancer stem cells (CSCs). Cancer stem cells (CSCs)
151
+ are stem-like tumor populations that are reported to
152
+ contribute towards tumor growth, maintenance, and
153
+ recurrence after therapy. Recent reports also link
154
+ resistance to conventional therapies and the metastatic
155
+ potential to CSCs. [4] A review by Mimeault and
156
+ Batra (2006) emphasizes the interactions among
157
+ certain developmental signaling factors and their
158
+ pathways which are involved in the regulation of the
159
+ self-renewal and/or differentiation of adult stem cells.
160
+ They describe that aberrant expression and activities
161
+ of hormones, cytokines and chemokines which
162
+ include estrogens, androgens, TGF-Notch etc., and
163
+ tumorigenic signaling elements such as telomerase,
164
+ NF-B and Myc-1 may enhance cancer stem cell
165
+ survival and contribute towards the malignant
166
+ potential of tumors. [5] In this context, preliminary
167
+ evidences suggest that Yoga modulates neural,
168
+ endocrine and immune functions at the cellular level
169
+ to bring about a balance. [6–8]
170
+ A study on 45 caregivers of dementia patients
171
+ showed that a brief daily yoga meditation intervention
172
+ may reverse the pattern of increased NF-κB-related
173
+ transcription of pro-inflammatory cytokines and
174
+ decreased Interferon response factors (IRF1) related
175
+ transcription of innate antiviral response genes. [9]
176
+ Another study on 49 patients with breast cancer
177
+ patients and 10 with prostate cancer has shown the
178
+ efficacy of mindfulness based yoga practices in
179
+ shifting the immune profile from one associated with
180
+ depressive symptoms to a more normal profile via
181
+ modulating T cell production of cytokines such as IL-
182
+ 4 (increased) and IFN-gamma (reduced) in addition to
183
+ reduced production of IL-10 by natural killer (NK)
184
+ cells. [10] Similarly another recent study on 86
185
+ patients with chronic inflammatory diseases has
186
+ shown that an intervention program which includes
187
+ asanas (postures), pranayama (breathing exercises),
188
+ stress management, group discussions, lectures, and
189
+ individualized advice can lead to reduction in stress
190
+ (plasma cortisol and β-endorphin) and inflammation
191
+ (interleukin [IL]-6 and tumor necrosis factor [TNF]-α
192
+ within a short duration of 10 days. [11] We had
193
+ shown that Yoga therapy enhances natural killer cells
194
+ [12], and also modulates stress and DNA damage in
195
+ breast cancer patients receiving radiotherapy. [13] In
196
+ another RCT that recruited 98 recently diagnosed
197
+ stage II and III breast cancer patients, compared the
198
+ effects of a yoga program with supportive therapy and
199
+ exercise rehabilitation on postoperative outcomes and
200
+ wound healing following breast surgery. A significant
201
+ decrease in plasma TNF alpha levels was observed
202
+ following surgery in the yoga group (P < 0.001), as
203
+ compared to the controls [13]. A study performed on
204
+ Development and Validation of a Need-Based Integrated Yoga Program for Cancer Patients
205
+
206
+ 271
207
+ 60 medical students demonstrated that integrated yoga
208
+ practices for 35 minutes daily for 12 weeks results in
209
+ better tolerance of stress and prevents the rise in
210
+ serum cortisol and INF- during exams, which is not
211
+ seen in the control group who did not undergo any
212
+ kind of yoga practice. [14]. A similar study conducted
213
+ on 50 healthy females to address the mechanisms
214
+ underlying hatha yoga's potential stress-reduction
215
+ benefits compared inflammatory and endocrine
216
+ responses of novice and expert yoga practitioners
217
+ before, during, and after a restorative hatha yoga
218
+ session, as well as in two control conditions
219
+ (movement control, and passive-video control).
220
+ Importantly, even though novices and experts did not
221
+ differ on key dimensions, including age, abdominal
222
+ adiposity, and cardio-respiratory fitness, the novices'
223
+ serum interleukin (IL)-6 levels were 41% higher than
224
+ those of experts across sessions, and the odds of a
225
+ novice having detectable C-reactive protein (CRP)
226
+ were 4.75 times as high as that of an expert. In
227
+ addition, experts produced less lipopolysaccharide-
228
+ stimulated IL-6 in response to the stressor than
229
+ novices. They concluded that Yoga may minimize
230
+ inflammatory responses to stressful encounters which
231
+ influences the burden that stressors place on an
232
+ individual [15] Thus, yoga therapy may bring about
233
+ moderation and balance in the expression and
234
+ activities of various hormones, cytokines and
235
+ tumorigenic signaling elements to reduce cancer stem
236
+ cell survival and thus may complement conventional
237
+ therapies in reducing cancer progression and
238
+ recurrence.
239
+ Yoga offers several techniques to restore
240
+ normalcy by introspection and self-knowledge.
241
+ Different schools use different set of these practices,
242
+ some using more of physical practices [16] and many
243
+ using meditation and/or breathing. All these practices
244
+ can be classified and compiled as need based
245
+ modules. In a meta-analytical review [17] Lin et al.
246
+ has compiled the techniques and the benefits used by
247
+ different researchers. Speca et al., 2000 [18] used
248
+ gentle Mindfulness based stress reduction program;
249
+ Cohen et al., 2004 [19] used Tibetan yoga which
250
+ included controlled breathing, mindfulness, postures
251
+ from Tsa lung (channels and vital breath), Trul khor
252
+ (magical wheel) in cases of lymphoma; Monti et al.,
253
+ 2006 [20] used gentle yoga (MBAT); Danhauer et
254
+ al.2009 [21] used asanas, pranayama, and deep
255
+ relaxation. Moadel et al., 2007 [22] used Hatha yoga
256
+ that included physical stretches, breathing and
257
+ meditation. The researchers from our institution
258
+ [Raghavendra rao [12,23–25], Banerjee [26], and
259
+ Vadiraja [12,23–25,27–29] used integrated yoga that
260
+ included the modules described in this study. This
261
+ article is an attempt to present the process of
262
+ development
263
+ of
264
+ holistic
265
+ modules
266
+ called
267
+ the
268
+ ‘Integrated Approach of Yoga Therapy for Cancer
269
+ (IAYTC)’ aimed at correcting the imbalances at
270
+ physical, mental, emotional and spiritual levels.

+
277
+ The discussion group consisted of eight members
278
+ with varied expertise. Three members were yoga
279
+ experts capable of providing guidance based on
280
+ ancient scriptures and its interpretations; two
281
+ scientists who had been involved in CAM research
282
+ and have had salient publications in the field of yoga
283
+ for cancer; one post graduate physician who is also a
284
+ practitioner of yoga for several years and two
285
+ oncologists
286
+ who
287
+ have
288
+ had
289
+ extensive
290
+ clinical
291
+ experience in the field of oncology. The Focused
292
+ group discussions (FGDs) were organized with a two
293
+ point agenda.(a) To assess the needs of the patient at
294
+ several phases of the treatment (surgery, RT, CT, HT,
295
+ post treatment) and (b) to evolve the modules of
296
+ integrated yoga intervention that could address these
297
+ needs. The team was involved at all stages of
298
+ discussion and development of the modules.

316
+ Ancient References to Cancer
317
+
318
+ Detailed review of literature, both traditional and
319
+ modern, in the field of yoga and mind body medicine
320
+ was conducted. Ancient yoga texts like Upanishads,
321
+ Bhagavat Gita, Patanjali Yoga Sutra, Yoga Vasishta,
322
+ Hatha Yoga Pradipika and Hatha Ratnavali were
323
+ reviewed to look for descriptions of mind body
324
+ diseases including cancer. Popular commentaries of
325
+ these texts were also reviewed to find interpretations
326
+ that could prove helpful in understanding cancer and
327
+ similar disorders. Citations from salient texts of the
328
+ ayurveda system of medicine were also looked into to
329
+ provide perspective to the disorder and treatment
330
+ mechanisms. A thorough search of scientific literature
331
+ shed light on the recent developments in the
332
+ understanding of cancer and its treatment modalities.
333
+ Published studies on alternative therapies used as
334
+ adjunct to conventional treatment were collected as
335
+ part of the literature review. The authors went on to
336
+ compile all the major theories that attempted to
337
+ explain the etiology of cancer, and made an attempt to
338
+ suggest a suitable remedy for the same. The
339
+ compilation of therapeutic modalities described in
340
+ Ayurveda and yoga included yoga postures, breathing
341
+ practices (pranayama), mind modulation techniques
342
+ (meditation),
343
+ and
344
+ lifestyle
345
+ advice.
346
+ Other
347
+ complementary alternative therapies were also looked
348
+ into, to find relevant practices, which had shown to
349
+ influence various aspects of cancer positively. A
350
+ master list of all these were compiled and presented to
351
+ the experts in a checklist form. The check list
352
+ included questions about all the psychological and
353
+ physical needs at different stages of Conventional
354
+ therapies (surgery or chemotherapy or radiation).
355
+ Inputs, with regards to the needs of a cancer
356
+ patient, as opined by oncologists, caregivers and
357
+ cancer patients, were collected based on the checklist
358
+ provided. Thus a need-based CAM module could be
359
+ designed and put forth as modules that could be used
360
+ as adjunct to conventional treatment.
361
+
362
+
363
+ Procedure
364
+
365
+ The study used the in-depth discussion method of
366
+ data collection with the purpose of compiling yoga
367
+ based traditional knowledge available in all yoga
368
+ scriptures. The process involved several small group
369
+ meetings, correspondences, visiting the experts in the
370
+ field and sitting together to practice and experience
371
+ the techniques that were prescribed. Using a
372
+ humanized method, rather than a restricted checklist
373
+ or questionnaire scoring method, offered flexibility
374
+ for the evolution of the concepts. Despite it’s time
375
+ consuming characteristics it helped the researchers to
376
+ interact as contributors in order to develop the
377
+ module. The extensive questions and discussion
378
+ sessions facilitated the development of the modules
379
+ by sharing each other’s experiences and developing
380
+ the steps of the modules that evolved.
381
+ The eight modules that evolved from these FGDs
382
+ were field tested through pilot studies. Further
383
+ revisions based on the feedbacks from the therapists
384
+ and the patients during these pilot studies helped in
385
+ finalizing the modules. These were used as the
386
+ interventions in our randomized control studies on
387
+ breast cancer that formed the material for the eight
388
+ publications on the complimentary role of IAYT in
389
+ breast cancer [13,23–29].

+ Results
393
+
394
+ Considering the need, expected side effects, the
395
+ energy levels and the psychological states of the
396
+ participants, eight modules evolved, the results of
397

403
+ at Five Aspects of Personality
404
+
405
+ According to yoga texts (30), the human system
406
+ consists of five components (panca kośa - five bodies)
407
+ Development and Validation of a Need-Based Integrated Yoga Program for Cancer Patients
408
+
409
+ 273
410
+ 1. Physical (Annamaya Kośa)
411
+ 2. Prana or subtle energy (Prānamaya Kośa)
412
+ 3. Instinctual mind (Manomaya Kośa)
413
+ 4. Intellectual
414
+ or
415
+ discriminative
416
+ mind
417
+ (Vignānamaya Kośa) and
418
+ 5. The blissfully silence state (Ānandamaya
419
+ Kośa)
420
+
421
+ Shvetashvatara Upanishad [31] describes that a
422
+ human being is in perfect health when he is
423
+ established in Ānandamaya Kośa which is the
424
+ unchanging state of being, the self. The living body is
425
+ a flux of continuous changes that is programmed to
426
+ live a full life span of about a century in perfect heath
427
+ if it is not disturbed by major calamities. Mind is the
428
+ most highly evolved and the most powerful entity of
429
+ the manifest universe. Disease begins in manomaya
430
+ kośa, the instinctual mind which is characterized by
431
+ likes and dislikes (Verse 49) [32] Due to wrong
432
+ notion of happiness the mind goes on seeking
433
+ relentlessly for objects of happiness; fear of failures
434
+ leads to distress and violent emotions; emotions are
435
+ defined as uncontrolled rewinding speed of thoughts
436
+ (chapter 5 verse 26) [33]; this becomes a habit;
437
+ suppressed emotions manifests as uncontrolled speed
438
+ in prānamaya kośa; speed and constriction of prana
439
+ flow to different organs result in violent activity in
440
+ Annamaya Kośa. As man goes through the ups and
441
+ downs of life (be it exposure to external onslaughts
442
+ like injury or infection, or emotionally challenging
443
+ situations), it sets off an imbalance.
444
+ The goal of treatment is to establish in a state of
445
+ complete mastery over all Kośas; this is possible by a
446
+ training to dwell in the state of alertful inner silence,
447
+ the Vignanamaya Kośa which is a state of total
448
+ contentment and freedom from all distress and
449
+ disease. (Chapter 2 Verse 12) [31] This is a state in
450
+ which one develops the ability to manipulate the laws
451
+ of nature within the body and outside the body.
452
+ (Chapter 1 Verse 4) [34] The integrated approach of
453
+ yoga provides a means to recognize and reverse the
454
+ damage by techniques at all these five levels.
455
+
456
+ References to Cancer (Arbuda ) in Āyurveda
457
+ Texts
458
+ Āyurveda, that evolved as a system of medicine
459
+ takes over from the understanding provided in yoga
460
+ texts. The imbalance due to excessive uncontrolled
461
+ speed in the prānamaya kośa that goes on to manifest
462
+ as physically visible symptomatic carcinomatous
463
+ mass in the annamaya kośa level has been elaborated.
464
+ Ayurveda is a highly developed system of medicine
465
+ that has descriptions of classification, progression,
466
+ manifestations and medical prescriptions for cancer.
467
+ According to āyurveda, the imbalance or vitiation of
468
+ any one of the three factors (vata, pitta and kapha)
469
+ results in disease and the balance can be restored by
470
+ holistic
471
+ life
472
+ style
473
+ modification
474
+ along
475
+ with
476
+ administration of drugs. Cancer is referred to as
477
+ Adhimāmsa and/or Arbuda under māmsa dhātu
478
+ pradośaja
479
+ (vitiated
480
+ muscle
481
+ tissue)
482
+ disorders.
483
+ Localization of the vitiated dośa to one part of the
484
+ body followed by metastasis (Prasara) is also
485
+ mentioned by Caraka. [35] The texts go on to explain
486
+ the stages of progression of arbuda. (Table 2) Arbuda
487
+ is considered to be due to vitiation with predominance
488
+ of Kapha Dośa that results in toxins (āma correlated
489
+ to free radicals) which get localized predominantly in
490
+ tissues, such as Rakta (blood), Māmsa (Muscle) and
491
+ Meda (Adipose). The treatment administered should
492
+ reduce the kapha dośa (Kaphahara), cleanse the
493
+ toxins of tissues, and reduce the āma (Māmsa and
494
+ Medo duñtihara).

+ In benign tumors: Abnormal cells confined to this stage only within the tissue of

502
+ Stage of uncontrolled growth.
503
+ 3. Prasara (spread)
504
+ Distant metastasis
505
+ Primary prasara
506
+ Invading adjacent tissues.
507
+ Secondary prasara
508
+ Migration to other parts away from the tissue of origin.

+ Localization in other tissues after metastasis.

513
+ 274
514
+ We find detailed decriptions of the clinical
515
+ manifestations
516
+ (Vyakta
517
+ arbuda)
518
+ and
519
+ also
520
+ the
521
+ complications (Bheda) of cancer in ayurveda texts.
522
+ Management of arbuda according to ayurveda
523
+ consists of two components:
524
+
525
+ a. Improving the immune stamina which is of
526
+ foremost importance and
527
+ b. Restore the balance of the three dośās by
528
+ drugs and life style modification.
529
+
530
+ The specific treatment for arbuda is classified
531
+ under
532
+ Bhaishajiya
533
+ Chikitsa,
534
+ the
535
+ conservation
536
+ therapies to revert the disease and Śalya Chikitsa
537
+ (Surgery). Surgical (Śastra Karma) procedures that
538
+ include Chhedana (partial or complete removal of
539
+ tissue), Lekhana (scraping or dissolving) and
540
+ Viśravaëa Aëuśastra Karma (draining with Para-
541
+ surgical methods). Ayurveda also describes radical
542
+ surgeries to clear the area of residual malignant cells.
543
+ Anuśastra Karma is the specialty of surgeons (Śalya
544
+ Chikitsaka)
545
+ which
546
+ includes
547
+ Agni
548
+ Karma
549
+ corresponding to radiation therapy and Kśāra Karma
550
+ that involves threading i.e. ligation of the tumor by
551
+ medicated threads. It has been mentioned that there is
552
+ possibility of recurrence of arbuda even after all
553
+ procedures are completed (37) and hence the need for
554
+ continued vigilance and administration of Rasāyana
555
+ therapies. This rasāyana therapy appears to be of
556
+ great value as an add-on to present day management
557
+ of cancer. Four groups of drugs that have Rasāyana
558
+ functions
559
+ have
560
+ been
561
+ mentioned:
562
+ (a)
563
+ Balya
564
+ (restoratives),
565
+ (b)
566
+ Jeevaniya
567
+ (vitalizers),
568
+ (c)
569
+ Brahmaëeeya (nutritious) and (d) Vayas-sthapana
570
+ (age stabilizers).
571
+ Rasāyana drugs correct the dośā’s disturbed
572
+ equilibrium and nourish the tissues (Dhātus). Many
573
+ scientific studies on rasāyana drugs such as āmalaki,
574
+ Aśwagandha, Guduchi, Yashtimadhu, Jivanti, Tulasi
575
+ and Pippali have shown their beneficial effects. Based
576
+ on some experimental studies in animal and human
577
+ subjects, it is proposed that rasāyanās may have
578
+ several rejuvenating properties such as anti-oxidant,
579
+ adaptogenic, immuno modulatory, cytoprotective,
580
+ neurotropic and or anabolic activities [38].
581
+
582
+
583
+ Step 2 –The Needs of Cancer Patients
584
+
585
+ All modules have the common purpose of
586
+ correcting the imbalances at all five aspects of the
587
+ personality through alert rest to the mind-body-
588
+ complex in general and to the effected organ in
589
+ particular. Each module consists of eight steps and
590
+ takes about 30 minutes to perform. All modules begin
591
+ with a selected prayer followed by Introspective
592
+ Perception/recognition and end with a resolve
593
+ followed by a closing prayer. The practices are to be
594
+ taught in ten sessions of one and half hours each.

+ Development and Validation of a Need-Based Integrated Yoga Program for Cancer Patients
650
+
651
+ 275
652
+ After a lecture for about 30 minutes to understand the
653
+ principle and back ground of the technique, the
654
+ participants
655
+ learn
656
+ the
657
+ module
658
+ under
659
+ guided
660
+ instructions for 50 minutes; this is followed by 10
661
+ minutes of interaction to check the experience. All
662
+ participants begin with basic modules based on the
663
+ abilities and needs. The therapist and the yoga
664
+ clinician assess the experience of the participant using
665
+ a check list before moving on to more advanced level.
666
+ [39].
667
+
668
+
669
+ Step 4 –Field Testing for Safety and Feasibility
670
+ of the Modules through Pilot Studies
671
+
672
+ Pilot studies were conducted (1995 to 2005) on
673
+ several cancer patients (breast, stomach, esophagus,
674
+ uterine cervix, colon, brain etc.) who were admitted
675
+ for IAYTC therapy at Arogyadhama, the residential
676
+ health home of VYASA. The modules were
677
+ introduced to these patients with regular follow up
678
+ and assessments. The feedbacks from the therapists,
679
+ about the feasibility, and from the patients, about their
680
+ experiences during the practices were documented.
681
+ This formed the basis for improvising the module of
682
+ IAYTC for the planned RCT for breast cancer.
683
+ A second level FGD was planned to finalize the
684
+ module by taking the inputs from the eight experts
685
+ who were involved initially in developing the
686
+ modules using a semi structured discussion method.
687
+
688
+
689
+ Step 5 –Efficacy trials through RCTs
690
+
691
+ Results of RCTs for efficacy
692
+ In our first RCT [13], 69 women with stage II or
693
+ III breast cancer were recruited to study the effect of
694
+ different modules of yoga during different stages of
695
+ conventional treatment starting from the first day of
696
+ diagnosis until the treatment was completed. During
697
+ the period of 2005-2008 when all our RCTs were
698
+ planned, the protocol of management at Bangalore
699
+ institute of oncology where the studies were
700
+ conducted, the standard conventional protocol was
701
+ surgery,
702
+ followed
703
+ by
704
+ radiation
705
+ therapy
706
+ and
707
+ chemotherapy (six cycles at an interval of three weeks
708

+ Effects of IAYTC after surgery
785
+ All participants were taught SKYM (in part) and
786
+ SMET in two days before surgery either as inpatients
787
+ or outpatient. They practiced DRT (ten minutes)
788
+ component of SMET four times a day for two days in
789
+ immediate post-operative period in the hospital;
790
+ SKYM practice was revised with a few additions
791
+ during their stay. They were asked to continue the full
792
+ practice (SKYM and SMET) daily for 30 minutes at
793
+ home. The results showed lesser number of days of
794
+ drain retention which resulted in lesser duration of
795
+ hospital stay after surgery implying economic
796
+ advantages (ref). They also showed significant
797
+ reduction in the number and severity of other
798
+ distressful symptoms after surgery (ref).

814
+ As they moved on and were preparing for
815
+ chemotherapy (CT) they went on to learn MIRT and
816
+ MEMT; they were given prerecorded audio CDs for
817
+ home practice; they were made to listen and practice
818
+ MSRT followed by PET during the hour long
819
+ chemotherapy infusion. As the CT progressed (six
820
+ cycles at an interval of three weeks between the
821
+ intravenous infusion therapy), the patients were taught
822
+ the other practices of VISAK and ANAMS which are
823
+ meant to allay the fear at subtler levels.
824
+ The results showed significant reduction in both
825
+ State and Trait anxiety (STAI); the CT related
826
+ distressful symptoms were significantly lower in the
827
+ yoga group [25]; the frequency and severity of post-
828
+ chemotherapy nausea and the anticipatory nausea
829
+ reduced
830
+ significantly.
831

838
+ and

944
+ There were positive correlations between the physical
945
+ and psychological symptoms. The activity levels were
946
+ correlated with fatigue, nausea and vomiting,
947
+ constipation and diarrhea. The perceived stress (PSS),
948
+ anxiety (STAI) and depression (HADS) were also
949
+ lower in the yoga group.
950
+ The salivary cortisol at 6am and the overall
951
+ pooled cortisol levels were significantly lower in the
952
+ yoga group of patients with stage II and III breast
953
+ cancer; and the scores for anxiety and depression
954

960
+ evidence to the immune system normalizing effects of
961
+ the integrated yoga modules [23]. The Plasma TNF-α
962
+ levels were significantly lower in the immediate post
963
+ operative period (7th day) in yoga group as compared
964
+ to control group (Mann-Whitney p<0.001) indicating
965
+ lower pro-inflammatory activity which could explain
966
+ faster healing. [13] Serum IgA were significantly
967
+ lower, %CD8+ and %CD56 counts were significantly
968
+ higher in yoga group pointing to better immune
969
+ adaptability towards the stressor [23].
970
+ Rao et al also went on to show a predictive
971
+ relationship between the emotional states (anxiety and
972
+ depression) and the outcome of surgery. The yoga
973
+ intervention played an important role in predicting the
974
+ number of days for drain retention, suture removal
975
+ interval, duration of hospital stay and post surgery and

+ TNF-α levels [13]. There were also significant

981
+ and

+ psychological variables such as anxiety, depression,

+ Discussion
990
+
991
+ This paper presents the six steps of developing
992
+ and providing the validity for the IAYTC modules
993
+ and also the proof of concept for their psycho-neuro-
994
+ humero-immunological basis. The concepts about the
995
+ origin and progression of disease that had evolved as
996
+ an introspective science in the east by yoga masters
997
+ were compiled. Eight feasible need based modules
998
+ were developed after several exchanges between the
999
+ experts. These were tested by pilot studies on patients
1000
+ with cancer at different sites. The efficacy was proved
1001
+ through high grade (pedro scoring of 6) [17]
1002
+ randomized control trials in breast cancer patients.
1003
+ Step 6 showed the predictive relationships between
1004
+ the psyche with the humoral and immunological
1005
+ measures.
1006
+
1007
+
1008
+ Comparisons
1009
+
1010
+ Since
1011
+ the
1012
+ first
1013
+ published
1014
+ research
1015
+ article
1016
+ evaluating the benefits of a support group therapy
1017
+ [40] in 1981, several researchers have used techniques
1018
+ like mindfulness-based stress reduction (MBSR),
1019
+ progressive muscle relaxation, Tibetan yoga as
1020
+ alternative forms of mindful and proactive non-
1021
+ pharmacological methodologies in combination with
1022
+ conventional treatment and seen a plethora of benefits
1023
+ in cancer care.
1024
+ There are many schools of yoga that are being
1025
+ practiced today in the world. These range from simple
1026
+ body postures either with or without the use of props
1027
+ to meditation. Iyengar yoga is one such school of
1028
+ yoga that prescribes simple asanas with supportive
1029
+ aids like pillows, wooden blocks and ropes that assist
1030
+ in reaching final position of difficult postures. Also
1031
+ breath modulation (pranayama) and meditation are
1032
+ practiced in these final postures. Other schools like
1033
+ Sudarshan Kriyā Yoga, Hatha Yoga, and Patanjali
1034
+ yoga have varying proportions of physical, breath and
1035
+ mind
1036
+ activities
1037
+ implemented
1038
+ through
1039
+ diverse
1040
+ techniques. As the premise for calling any practice
1041
+ ‘yoga’ is clearly defined in ancient Indian literature as
1042
+ ‘chitta vritti nirodhah’ (voluntary mastery over the
1043
+ modifications of the mind)(chapter 1 verse 2) [34] and
1044
+ offered eight or more practices to achieve this,
1045
+ researchers have the freedom to select and modify the
1046
+ intervention to suit the desired objectives.
1047

1050

1051
+ [19],
1052

+ [18,41,42] and simple awareness [43] techniques have
1054
+ shown benefits to cancer patients at physical,

1056
+
1057

1058
+ psychological, psychosocial levels and consistently
1059
+ reported an improvement in quality of life outcomes.
1060
+ Physical benefits included reduction in fatigue
1061
+ [21,44,45], pain [44,46] and symptoms [46,47]. Also
1062
+ improvements in sleep measures [19] and immune
1063
+ parameters [18] have been reported. Research has also
1064
+ shown that a spectrum of psychological abnormalities
1065
+ like distress [17,46], stress [17,18,48], anxiety
1066
+ [17,21,46,48], depression [17,21,46], affect[21] and
1067
+ mood [47], can be corrected through mind body
1068
+ interventions.
1069
+ Psychosocial variables like mental adjustment
1070
+ [48] and acceptance [44] are also affected by
1071
+ inculcating restorative yoga related techniques into
1072
+ the treatment process. Quality of life as measured by
1073
+ several sub scales relating to physical QOL,
1074
+ psychological QOL, Health related QOL and overall
1075
+ QOL have shown consistent improvements [21,49]. A
1076
+ review article suggests that these QOL measures need
1077
+ to play a more important role in planning treatment
1078
+ regimen for cancer patients [50].
1079
+
1080
+
1081
+ Mechanism -Yoga and Cancer Stem Cells
1082
+
1083
+ Recent reports link resistance to conventional
1084
+ therapies and the metastatic potential to a stem-cell-
1085
+ like tumor population, termed cancer stem cells
1086
+ (CSCs) [51,52]. CSC population survives injury due
1087
+ to radiations and chemotherapy through their ability
1088
+ to restrict DNA damage by reducing reactive oxygen
1089
+ species and thus, continues to propagate the tumor by
1090
+ preventing DNA damage [52]. It appears that the
1091
+ elimination of this minority of cancer progenitor cells
1092
+ with stem cell-like properties [53] is essential for the
1093
+ development of more effective curative treatments
1094
+ against cancer.
1095
+ Two factors which facilitate cancer stem cell
1096
+ survival are; aberrant expression of tumor signaling
1097
+ pathways [52] and hypoxia [54]. Hypoxia induced
1098
+ signaling is mediated by Hypoxia-inducible factor
1099
+ (HIF), which is critical for stem cell survival and self-
1100
+ renewal [4]. Apart from balancing the neuro-
1101
+ endocrino-immunological
1102
+ pathways
1103
+ [7],
1104
+ Yoga
1105
+ practices especially pranayamas have been proven to
1106
+ increase blood oxygen saturation levels [55].
1107
+ Proposed IAYTC Module thus, has the potential to
1108
+ make CSCs more susceptible to radiation and
1109
+ chemotherapy
1110
+ induced
1111
+ damage
1112
+ probably
1113
+ by
1114
+ harmonizing tumor signaling pathways and by
1115
+ reducing Hypoxia-induced transcription of HIFs,
1116
+ thereby reducing the progression and recurrence of
1117
+ cancer.
1118
+
1119
+
1120
+ Summary
1121
+
1122
+ The yoga texts propose a psycho-physical model
1123
+ of cancer. It is an imbalance caused by persistent
1124
+ uncontrolled speeded up recycling of thoughts
1125
+ (emotions) in the psyche that manifests as cancer at
1126
+ the physical level. The aim is introspective self-
1127
+ correction of the inner violence and reaches a blissful
1128
+ silent state of the mind. Eight modules of practices to
1129
+ correct the imbalances evolved through focused group
1130
+ discussions. Corrections in the modules were
1131
+ implemented after getting feedbacks from field testing
1132
+ through pilot studies. Randomized control studies
1133
+ provided more evidence to the value of these IAYTC
1134
+ modules
1135
+ as
1136
+ add-on
1137
+ therapy.
1138
+ Predictive
1139
+ and
1140
+ correlational relationship between psychological with
1141
+ immunological and humoral variables was considered
1142
+ as supportive evidence for the scriptural basis for the
1143
+ modules.
1144
+
1145
+
1146
+ Limitations of the Study
1147
+
1148
+ The study is a retrospective presentation of the
1149
+ steps that were followed over the years and not a
1150
+ prospective planned study to assess the validity and
1151
+ reliability of the modules. Statistically acceptable
1152
+ scoring for the check list was not used during all
1153
+ group discussions as the format was semi structured.
1154
+ Not all members of the focused group met during all
1155
+ discussions and some of the meetings were not
1156
+ documented. Statistical calculations of split half
1157
+ reliability were not planned.
1158
+
1159
+
1160
+ Strengths and Recommendations from the
1161
+ Study
1162
+
1163
+ Eight published articles that have tested the
1164
+ feasibility, safety and efficacy of these eight modules
1165
+ of IAYTC is the major strength of this work. These
1166
+ Development and Validation of a Need-Based Integrated Yoga Program for Cancer Patients
1167
+
1168
+ 279
1169
+ modules developed on the basis of time tested
1170
+ knowledge base of 2000 to 7000 years by the eastern
1171
+ introspective researchers offers many more tools to
1172
+ modern
1173
+ cancer
1174
+ management
1175
+ protocols.
1176
+ The
1177
+ uniqueness of these modules is that these can be
1178
+ added on safely to any of the protocols of
1179
+ management of cancer of different stages at any site.
1180
+ We recommend incorporation of these tested modules
1181
+ in all cancer management protocols to reduce the
1182
+ toxicity and side effects which has been one of the
1183
+ major limitations of most of the therapeutic tools
1184
+ available today. This would add on to better
1185
+ acceptability through improved quality of life.
1186
+
1187
+
1188
+ Suggestions for Future Work
1189
+
1190
+ More studies to establish the validity and
1191
+ reliability using structured approach is recommended.
1192
+ These modules have to be tested in different races;
1193
+ this is now going on as a NIH funded project at MD
1194
+ Anderson’s center for cancer, Houston, USA. Can
1195
+ these techniques replace the existing modalities of
1196
+ management is a major question that has to be
1197
+ addressed
1198
+ by
1199
+ innovative
1200
+ ethically
1201
+ acceptable
1202
+ experimental designs.
1203
+
1204
+
1205
+ Conclusion
1206
+
1207
+ Among the various CAM treatments available,
1208
+ yoga has proved to be useful in management of
1209
+ cancer. Eight modules of IAYTC to be introduced
1210
+ systematically as add-on to conventional therapies
1211
+ (surgery, radiation, and chemo) of cancer with
1212
+ additional benefits of improved quality of life, stress
1213
+ reduction, correction of HPA axis and immune system
1214
+ imbalances offers many more tools to the existing
1215
+ protocols of cancer management.

+ Context and Aim: Yoga has been found to be effective in the management of stress. This paper describes the development
4
+ of a yoga program aimed to reduce burden and improve coping of family caregivers of inpatients with schizophrenia in India.
5
+ Materials and Methods: Based on the assessment of caregiver needs, literature review, and expert opinion, a ten-day group
6
+ yoga program was initially developed using the qualitative inductive method of inquiry. Each day’s program included warm-up
7
+ exercises, yogic asanas, pranayama, and satsang. A structured questionnaire eliciting comments on each day’s contents was
8
+ given independently to ten experienced yoga professionals working in the field of health for validation. The final version of
9
+ the program was pilot-tested on a group of six caregivers of in-patients with schizophrenia admitted at NIMHANS, Bangalore.
10
+ Results: On the question of whether the program would help reduce the burden of caregivers, six of the ten experts (60%)
11
+ gave a rank of four of five (very much useful). Based on comments of the experts, several changes were made to the program.
12
+ In the pilot-testing stage, more than 60% of the caregivers assigned a score of four and above (on a five-point Likert scale, five
13
+ being extremely useful) for the overall program, handouts distributed, and performance of the trainer. Qualitative feedback of
14
+ the caregivers further endorsed the feasibility and usefulness of the program.
15
+ Conclusion: The developed yoga program was found to be acceptable to caregivers of in-patients with schizophrenia.

34
+ INTRODUCTION
35
+ Yoga models described by earlier authors have provided
36
+ their own rationale behind the choice of yoga asanas/
37
+ program.[1-3] However, there is no mention whether these
38
+ programs have been endorsed by other specialists in the
39
+ field than the researcher themselves. Also, there is no
40
+ literature which discusses the development of a yoga
41
+ program which attempts to match the expressed needs of
42
+ the participants.
43
+ Only two studies have looked at development and
44
+ feasibility testing of yoga programs for caregivers of
45
+ persons with disability. Puymbrock et al.[4] tested the
46
+ feasibility of a yoga program on the physical health and
47
+ coping of informal caregivers who cared for a person
48
+ with a disease or disability in USA. Waelde et al.[5]
49
+ conducted a pilot study of a yoga and meditation
50
+ intervention called “Inner Resources” for dementia
51
+ caregiver stress in USA.
52
+ The above studies focus more on feasibility testing rather
53
+ than on the development of a yoga program. The cultural
54
+ applicability of the studies in an Indian setting would
55
+ also require testing. Furthermore, the needs expressed
56
+ by the caregivers of persons with dementia[6-9] is different
57
+ from that of the needs of caregivers of persons with
58
+ schizophrenia.[10] As there were no Indian studies which
59
+ explored the development and feasibility testing of yoga
60
+ program based on the needs of caregivers, we undertook
61
+ the systematic development of a yoga program based on the
62
+ needs of caregiver of persons suffering from schizophrenia.

66
+ MATERIALS AND METHODS
67
+ The study was reviewed and approved by the Institute’s
68
+ ethics committee. Written informed consent of the mental
69
+ health professionals who helped in validation of the
70
+ program and family caregivers who participated in the pilot
71
+ study was obtained. A sociodemographic sheet eliciting
72
+ information on their age, occupation, monthly income, and
73
+ marital status was filled up by the researcher for both the
74
+ mental health professionals and family caregivers.
75
+ The inductive method of inquiry (quintessence of
76
+ qualitative research) in which general principles (theories/
77
+ programs) are developed from specific observations was
78
+ used to develop and test the feasibility of the program. The
79
+ development of the yoga program was conducted in two
80
+ stages. Stage-one involved development of the content and
81
+ methodology for the yoga program. Stage-two involved face
82
+ and content validation of the program. The feasibility of the
83
+ program was tested in Stage-three of the study where the
84
+ program was pilot-tested and feedback from the caregivers
85
+ who participated in the program was elicited. The process
86
+ involved in each stage of the development and feasibility
87
+ testing of the program is delineated below [Figure 1].
88
+ Stage-One: Program development
89
+ Initially, a yoga program was developed by matching
90
+ the needs of the caregivers.[10] Classical texts such as
91
+ Patanjali Yoga Sutra,[11] Rigveda,[12] Gheranda Samhita,[13]
92
+ Hatharatnavali,[14] and Hathayogapradipika[15] were
93
+ reviewed to understand the asanas/practices that would
94
+ help directly or indirectly deal with each of the needs.
95
+ To help warm up the body to practice the asanas and
96
+ pranayama, jogging, cycling, and hands in and out
97
+ breathing was incorporated in the beginning of each day’s
98
+ program (Nagendra, 2008).
99
+ Suryanamaskara a set of yogic postures done in a sequence
100
+ of postures routinely followed in several yoga schools,
101
+ helps in bringing about general flexibility of the body and
102
+ improving mental health as a preparation for asanas and
103
+ pranayama (Satyananda Saraswati, 2008; Yogendra., 1997).
104
+ Even the foremost classical text (Rigveda, 1st Mandala,
105
+ 50th Sukta) emphasizes the benefits of the practice in
106
+ destroying physical illnesses and the diseases of the
107
+ heart (mind) [‘udyannadya mitramaha arohannuttaram
108
+ divam /Hrdrogham mamasurya harimanam ca nasaya //
109
+ (1st  Rucha). “Rising this day, O rich in friends, ascending
110
+ to the loftier heaven, Surya remove my hearts disease, take
111
+ from me this yellow hue…”].
112
+ The goal of yoga practices in context of the needs expressed
113
+ by the caregivers (such as managing illness behavior,
114
+ managing socio-occupational concerns, physical and
115
+ mental health, and managing marital and sexual issues of
116
+ the patient) was to enable the caregivers to think clearly,
117
+ have equanimity in emotions, improve their decision
118
+ making as well as their response to a situation, and
119
+ improve their attention. A review of classical yoga texts
120
+ (Gheranda Samhita, Hatharatnavali, Hathapradipika) and
121
+ contemporary yoga textbooks (Yogendra., 1997, Satyananda
122
+ Saraswati, 2008; Nagendra, 2008) showed that asanas such
123
+ as Padahastasana, ardhachakrasana, Vajrasana, Vakrasana,
124
+ Salabhasana Bhujangasana, Savasana, Nadanusandana,
125
+ Matsyasana, Nadishuddhi, Bhramhari, and Kapalabhatti
126
+ had direct or indirect benefits in improving caregiver’s
127
+ ability to think clearly, improve their decision making/
128
+ response to a situation/attention, and equanimity of
129
+ emotions.
130
+ The satsang was used to educate the caregivers on how yoga
131
+ could help tackle their needs and help in rehabilitation
132
+ of the patient.
133
+ Table 1 depicts the details of the yoga program developed
134
+ in accordance with the assessed needs of caregivers. The
135
+ table enlists practices that are applicable/not applicable in
136
+ fulfilling the six assessed needs of the caregivers.
137
+ The ultimate aim of the yoga program was to reduce the
138
+ burden of the caregivers either by addressing their needs
139
+ or by developing yoga program which in turn would equip
140
+ them with the ability and skills to reduce their burden—
141
+ irrespective of the fulfillment of needs. As not all needs
142
+ could be theoretically addressed by teaching yoga, we
143
+ focused on the reduction of burden (aim of the study),
144
+ irrespective of the expressed needs.
145
+ Thus, the framework of the yoga program was based on
146
+ Integrated Yoga Therapy (IAYT) model developed by
147
+ Swami Vivekananda Yoga Anusandhana Samasthana[3]
148
+ (SVYASA). This model incorporated the “Self Management
149
+ of Excessive Tension (SMET)/ Cyclic meditation” approach
150
+ which reflected not only the aim of the current study
151
+ of reducing burden and improving coping among the
152
+ caregivers, but also directly or indirectly dealt with the
153
+ Figure 1: Process of Inductive method of program development

+ International Journal of Yoga  Vol. 5  Jan-Jun-2012
155

156
+ Jagannathan, et al.: Need-based yoga program for caregivers of patients with schizophrenia
157
+ six broad categories of assessed needs elucidated in the
158
+ first phase of this study.[10]
159
+ Stage-Two: Face and content validation
160
+ For the purpose of content validation of the program, the
161
+ researcher developed a structured questionnaire eliciting
162
+ dichotomous responses such as Yes/No and qualitative
163
+ comments on the appropriateness of each exercise and
164
+ asana selected as a component of the entire yoga program.
165
+ Ten experienced yoga therapy and research professionals
166
+ (in and around Bangalore) were approached individually
167
+ for the validation. The average number of years of work
168
+ experience (SD) of the experts after their formal education
169
+ was 14.8 (14.1) years. Through this methodology of content
170
+ - validation, the researcher accumulated a list of comments
171
+ for incorporating into yoga program. For face validation of
172
+ the program, the researcher asked each of the professionals
173
+ to rate the likelihood of the program achieving its objective
174
+ of helping the caregivers reducing their burden and stress
175
+ - on a five point Likert scale.
176
+ To arrive at a consensus on the contents and methodology of
177
+ the yoga program, three rounds of iteration was conducted
178
+ among the yoga professionals, i.e., the researcher made
179
+ changes to the program based on comments given by the
180
+ professionals and went back (iteration) to them for their
181
+ further inputs on the modified program, three times before
182
+ all the ten experts agreed on the contents and methodology
183
+ (data saturation).
184
+ A standardized script of the final version of the yoga
185
+ program was developed on incorporating the comments
186
+ of the ten experts. The script included list of practices and
187
+ asanas along with their step-wise procedure and pictures,
188
+ detailed notes on each satsang topic (seven topics – one
189
+ topic for each day; the script is available from the authors
190
+ on request). A handout explaining the contraindication of
191
+ practicing certain asanas during ailments along with the
192
+ order and list of yogic practices and their pictures was
193
+ developed in four languages (English, Hindi, Kannada,
194
+ and Tamil) for distribution to the participants. Each
195
+ satsang topic and notes was converted into power point
196
+ slides in the four languages for ease of presentation to the
197
+ participants.
198
+ Stage-Three: Pilot study and feasibility
199
+ The final version of the yoga program was pilot-tested on
200
+ a group of eight in-patient family caregivers who were
201
+ residing at National Institute of Mental Health and Neuro
202
+ Sciences (NIMHANS) in Bangalore, India (NIMHANS has
203
+ a 900-bed teaching hospital with training and research
204
+ facilities in psychiatry and other neurosciences) during
205
+ the period of the study.
206
+ Caregivers of patients with a diagnosis of schizophrenia
207
+ were included in the study if they were to continue to
208
+ provide care for them following discharge. Caregivers with
209
+ psychiatric or neurological disorders and those caring for
210
+ another relative with psychiatric illness were excluded.
211
+ Of the eight caregivers recruited in the pilot study, three
212
+ caregivers dropped out during the intervention. The mean

+ intervention included sessions of about one hour daily for a
406
+ period of seven days. During the entire period of the study,
407
+ the ill relative continued to receive the routine treatment
408
+ prescribed by the doctors at NIMHANS. At the end of the
409
+ seven days, the caregivers were asked to fill a structured
410
+ feedback form on their overall rating of the program,
411
+ trainer, and the handouts distributed during the sessions.
412
+ Descriptive analysis of the quantitative (Likert ratings)
413
+ feedback and content analysis of the qualitative feedback
414
+ received from the caregivers was conducted. Each and
415
+ every comment was given importance and the researcher
416
+ tried to accommodate all of it into the yoga program.
417
+ RESULTS
418
+ As the main objective of the study was to develop and test
419
+ the feasibility of a need-based yoga program for inpatient
420
+ caregivers, the results reflect the qualitative data acquired
421
+ at two levels: at the validation stage and at the pilot stage.
422
+ At validation stage
423
+ For content validation, experts were asked for their
424
+ feedback on the components that should be added in
425
+ the IAYT model [incorporating the ‘Self Management of
426
+ Excessive Tension’ (SMET)/ Cyclic meditation approach].
427
+ The suggestions given by the experts are elicited below:
428
+
429
+ Breathing exercises (like ‘Bhujangasana breathing’ and
430
+ ‘Salabhasana breathing’) need to be included.
431
+
432
+ Chanting either with the breathing exercises or
433
+ separately (Nadanusandana) should be included
434
+ as it would increase the exhalation: inhalation
435
+ ratio and hence (in all probability) stimulate the
436
+ parasympathetic tone, which would be useful in stress
437
+ reduction.
438
+
439
+ Emphasis on awareness of calmness and silence from
440
+ within during asana practice is of vital importance.
441
+ For this reason, explanations of the purpose of the
442
+ asanas should be done in the introduction or during
443
+ ‘Satsang’ at the end.
444
+
445
+ Teach the full round of 13 practices of ‘suryanamaskara’
446
+ with invocation at the beginning of each for at least
447
+ six minutes.
448
+
449
+ I am personally used to ‘Padahastasana’ at the end,
450
+ once the body and legs are softened. It is a good
451
+ preparation for final ‘Savasana’ (or Quick Relaxation
452
+ Technique - QRT).
453
+
454
+ ‘Paschimuttanasana’ or ‘Halasana’ can feature in
455
+ the list as these two (possibly in combination with
456
+ Sarvangasana) are ideal for loosening up the region
457
+ of the ‘Muladhara chakara’ and inducting the shakti
458
+ to flow more strongly.
459
+
460
+ Twist poses are excellent for refreshing blood flow
461
+ to all the inner organs in the abdomen, from which
462
+ the renewed flow of the various pranas in the nadis/
463
+ meridians transform how a person feels. In this
464
+ context, even the rotating swings performed during
465
+ loosening exercises could be useful as a 1-minute
466
+ practice during the warm-up period.
467
+
468
+ Sarvangasana is the best position for becoming
469
+ aware of the inner silence and could well be put at
470
+ the beginning.
471
+
472
+ To add deep breathing, nadishodhana and Kapalabhatti
473
+ in the program which should be practiced frequently,
474
+ example: while attending satsang.
475
+
476
+ Caregivers need to consciously focus on the ‘stretch’
477
+ which maintains easy and relaxed breathing during
478
+ asana performance. This has the most powerful
479
+ calming and integrating effect.
480
+ Based on the comments given by the experts, the yoga
481
+ program was appropriately modified and developed for a
482
+ seven-day period of one hour each (inclusive of 45 minutes
483
+ of practices and 15 minutes of satsang). The program
484
+ started with loosening exercises, five rounds of 13 step
485
+ ‘suryanamaskara’ excluding invocation (due to lack of
486
+ time), cyclic meditation, ‘Kapalabhatti’, ‘Nadishuddhi’
487
+ pranayama, and chanting (Nadanusandana). Emphasis
488
+ was on awareness of calmness and silence from within
489
+ during asana practice. For this reason, explanations about
490
+ the benefits of each asana was given during the practice
491
+ and included as topics for the ‘Satsang’ at the end of each
492
+ day’s program. Caregivers were consciously taught to
493
+ focus on the ‘stretch’ with maintaining easy and relaxed
494
+ breathing during asana performance. Paschimuttanasana’,
495
+ ‘Halasana’, and Sarvangasana were excluded from the
496
+ program as the authors felt that it would be challenging
497
+ for the caregivers to learn and practice these asanas due
498
+ to their age.
499
+ For face validation, on asking whether the overall yoga
500
+ program would achieve its objective of helping the
501
+ caregivers reduce their burden and stress, six of the ten
502
+ experts (60%) gave a rank of four (very much useful).
503
+ At pilot stage
504
+ Of the five caregivers who underwent the pilot yoga
505
+ program, four of them assigned a score of four or five (on a
506
+ International Journal of Yoga  Vol. 5  Jan-Jun-2012
507
+ 46
508
+ Jagannathan, et al.: Need-based yoga program for caregivers of patients with schizophrenia
509
+ five-point Likert scale, five being extremely useful) for the
510
+ overall program, handouts distributed, and performance of
511
+ the trainer. Qualitative feedback of the caregivers further
512
+ endorsed the feasibility and usefulness of the program
513
+ (M: Member):
514
+
515
+ “The entire program was good as it taught us the
516
+ importance of taking care of our own health. I liked
517
+ to attend the program” (M1).
518
+
519
+ “I liked the program as it helped to reduce my physical
520
+ problem (leg pain) and gave me a relaxed feeling” (M2).
521
+
522
+ “The program helped me to understand the problem
523
+ (of my health) and find a way to get relief. I liked the
524
+ chanting of slokas the best.”(M3)
525
+
526
+ “The instructor and her way of teaching were very
527
+ good. Also I feel Suryanamskar benefitted me the
528
+ most.” (M5).
529
+ DISCUSSION
530
+ The challenges faced by caregivers in dealing with their
531
+ relative who is suffering from schizophrenia are varied
532
+ and extensive. A number of interventions offered to
533
+ family members with patients of schizophrenia have
534
+ been developing to help deal with the burden and stress
535
+ of caring. The current study in an attempt to develop a
536
+ need-based yoga program describes the steps involved in
537
+ the program development, content and face validation,
538
+ and pilot testing of the program.
539
+ There is hardly any research study that discusses the
540
+ development and effectiveness of standardized training
541
+ programs based on the assessed needs of caregivers of
542
+ persons suffering from schizophrenia in India. This
543
+ attempt to develop a structured intervention program
544
+ based on the holistic coverage of all the needs of the
545
+ family caregivers—via a participatory approach (i.e., the
546
+ caregivers themselves opined their needs and areas they
547
+ required training in which was incorporated to develop
548
+ the program) is of significant importance, even though we
549
+ were unable to match all the needs of the caregivers to the
550
+ contents of yoga program (where the focus was more to
551
+ reduce burden of the caregivers).
552
+ The yoga program was developed after a lot of collective
553
+ thought and scientific rigor. The possible effects of each
554
+ asana and exercise on the physiology and mental health of
555
+ the caregiver was weighed to retain the asana/exercise in
556
+ the program (whether it physiologically reduced the stress
557
+ and mentally reduced burden and improved coping). A
558
+ number of related factors such as age and possible health
559
+ conditions of the caregiver were taken into consideration
560
+ before incorporating a particular asana/exercise into the
561
+ program. Experts had opined the importance of educating
562
+ the caregivers about the benefits of the asanas/exercises at
563
+ the onset or during the satsang—incorporation of which
564
+ helped caregiver gain greater awareness of the subtle
565
+ changes in the physical and mental state over the period
566
+ of the program.
567
+ Though a few experts were skeptical of the effects of yoga
568
+ in helping caregivers relieve their burden and stress,
569
+ majority of them felt that the overall yoga program would
570
+ achieve its objective. Skepticism could be valid, as both
571
+ concepts of burden and stress are complex. Varied practical
572
+ issues could weigh on the caregivers’ mind when asked to
573
+ rate their burden—example, financial burden and stress
574
+ in caregivers is a prolonged effect of enduring certain
575
+ unresolved practical problems.
576
+ Another critique of the above program was that it was too
577
+ short to enable the caregivers to imbibe the yoga techniques
578
+ into daily practice. Traditional yoga therapists would
579
+ argue that the seven-day program could be too short to
580
+ perceive any effects of yoga. However, development of an
581
+ elaborate program in the current setting would have its
582
+ own limitations, mainly being that of high drop-outs and
583
+ inability to reach out to majority of the caregivers. This
584
+ is mainly because the average period of stay of a patient
585
+ and his caregiver in any psychiatric setting is less than one
586
+ week. The statistics at NIMHANS depict the average stay of
587
+ in-patients and their caregivers as three weeks. However,
588
+ as the patient is usually acutely symptomatic in the first
589
+ week, it is challenging to conduct any intervention with
590
+ the caregiver alone, as there is no one else to take care of
591
+ the patient. There are many barriers like convincing people
592
+ to travel long distances from their homes to a center for
593
+ yoga therapy/psychosocial interventions[16] once they are
594
+ discharged. In this context, we believe that our seven-day
595
+ program was pragmatic in its timeline and achieved its goal
596
+ of reaching out to maximum caregivers who were admitted
597
+ in the wards along with their patients at NIMHANS, during
598
+ the study period.
599
+ The sociodemographic profile of the caregivers who
600
+ participated in the programs was consistent with that
601
+ of earlier studies on Indian caregivers of persons with
602
+ schizophrenia.[17,18] All caregivers were family members.
603
+ Most of them were parents, who were working and were
604
+ into late adulthood or old age.
605
+ The feasibility and usefulness of the yoga program was
606
+ endorsed by the caregivers. The fact that the caregivers
607
+ were able to perform all the asanas properly, understand
608
+ its benefits, and feel relaxed indicates that the program
609
+ was feasible and could be tested on a larger population.
610
+ CONCLUSION
611
+ This study is one of the first studies to use a sound
612
+ methodology of inductive enquiry model for the
613
+ 47
614
+ International Journal of Yoga  Vol. 5  Jan-Jun-2012
615
+ Jagannathan, et al.: Need-based yoga program for caregivers of patients with schizophrenia
616
+ development of a need-based yoga program for caregivers
617
+ of in-patients with schizophrenia in India. These findings
618
+ are highly indicative and future studies could test the
619
+ efficacy of the program with a larger quantitative sample
620
+ to reconfirm its validity, reliability, and generalizability.
621
+ The researchers plan to test the efficacy of this validated
622
+ yoga program for family caregivers of inpatients with
623
+ schizophrenia in India in a larger randomized control trial,
624
+ as an outcome of this study.

+ Abstract:
40
+ Background: Parkinson’s disease (PD), a progressive neurodegenerative disease, affects motor and nonmotor
41
+ functions, leading to severe debility and poor quality of life. Studies have reported the beneficial role of yoga in
42
+ alleviating the symptoms of PD; however, a validated yoga module for PD is unavailable. This study developed
43
+ and validated an integrated yoga module(IYM) for PD.
44
+ Methods: The IYM was prepared after a thorough review of classical yoga texts and previous findings. Twenty
45
+ experienced yoga experts, who fulfilled the inclusion criteria, were selected validating the content of the IYM.
46
+ A total of 28 practices were included in the IYM, and each practice was discussed and rated as (i) not essential,

56
+ Introduction
57
+ Parkinson’s disease (PD) is one of the most common progressive neurodegenerative disorders and is character-
58
+ ized by various motor symptoms such as resting tremors, bradykinesia, rigidity, and imbalance. As the disease
59
+ progresses, additional symptoms, such as autonomic dysfunction, cognitive impairment, neurobehavioral ab-
60
+ normalities, and sensory abnormalities, such as anosmia, paraesthesia, and pain, also develop [1, 2].
61
+ A survey reported that 6.3 million persons had PD [3]. PD is predominantly observed in men [4, 5]; it affects
62
+ the financial aspects and quality of life of patients and makes them dependent on others [6]. Levodopa is the
63
+ most potent drug used in the conventional management of PD [7]. However, this drug has various adverse
64
+ effects such as psychosis, motor fluctuations, and dyskinesia. Dopamine resistance can cause several motor
65
+ difficulties, such as speech impairment, abnormal posture and gait, and balance problems, and non-motor
66
+ symptoms such as autonomic dysfunction, mood and cognitive impairment, sleep problems, and pain [8]. A
67
+ survey reported that 40 % of patients with PD used at least one alternative therapy [5].
68
+ Yoga
69
+ Yoga is a mind–body intervention and comprises physical practices (asanas), breathing techniques
70
+ (pranayama), and meditation and relaxation techniques. Yoga is a popular complementary and alternative
71
+ medicine modality worldwide. Studies have reported several health benefits of yoga for clinical conditions such
72
+ as asthma [9], coronary artery disease [10], diabetes mellitus [11], pulmonary tuberculosis [12, 13], epilepsy, fi-
73
+ bromyalgia, and arthritis [14].

80
+ Furthermore, studies have reported a positive role of yoga in chronic neurological conditions such as mul-
81
+ tiple sclerosis [15], carpal tunnel syndrome [16], migraine [17], and stroke [18].Yoga was reported to improve
82
+ strength and flexibility [19].
83
+ Yoga and neurological disorders
84
+ The practice of yoga improves the measures of gait, fatigue, quality of life, and physical function in several
85
+ neurological conditions [15, 20–22].
86
+ Yoga is beneficial in several neurological conditions such as multiple sclerosis and stroke [23]. It improves
87
+ fatigue, cognitive function [24], balance, and quality of life in multiple sclerosis [15, 25] and improves the balance
88
+ confidence and quality of life of patients with stroke [18, 22, 26].
89
+ PD and yoga
90
+ In a randomized controlled trial, 13 patients with PD were divided into the Iyengar yoga (intervention) and
91
+ waitlist-control groups. The intervention group performed 60 min of Iyengar yoga daily for 12 weeks. At the
92
+ end of 12 weeks, marked improvement was observed in the United PD Rating Scale scores; motor performance;
93
+ Berg Balance Scale scores; and gait, hip, knee, ankle, and shoulder range of motion in the intervention yoga
94
+ group compared with the control group [27].
95
+ In another single-group prepost study, 10 adults with PD performed a 60-min session of Hatha Yoga weekly
96
+ for 8 weeks, following which considerable improvements were observed in anxiety, depression, functional
97
+ strength, and leg flexibility [28].
98
+ In a similar pre-post study, 17 participants with PD underwent a 10-week Iyengar yoga program consisting
99
+ of 2-h yoga classes and a daily 30-min home practice session. After the intervention, marked improvements
100
+ were noticed in walking speed, Short Physical Performance Battery scores, balance, and Falls Efficacy Scale
101
+ scores [29].
102
+ Another study assessing nine adults with PD, who participated in a twice weekly Hatha yoga program
103
+ (75-min duration) for 12 weeks, reported remarkable improvements in physical measures (chair stand and sit-
104
+ and-reach test) and depression [30].
105
+ A systematic review on PD concluded that yoga alleviates PD-related symptoms, including motor function,
106
+ muscle strength, flexibility, balance, gait difficulties, poor balance, and lower-body weakness. It also improves
107
+ depression, sleep, and quality of life of patients with PD [31].
108
+ Apart from these studies, three single-case studies of patients with PD aged 57, 59, and 69 years who un-
109
+ derwent yoga interventions for 6 months (90-min daily), 3 weeks (60-min daily), and 8 months (60-min daily),
110
+ respectively, reported improvements in the body awareness and motor function of these patients [32].
111
+ Other alternative therapies in PD
112
+ Approximately 40 % of patients with PD use alternative therapies. Ayurveda, Tai Chi, mindfulness, massage
113
+ therapy, and acupuncture are the most commonly used alternative therapies for PD [33, 34]. Most of these
114
+ therapies have promising roles in PD management [34]. An ayurvedic herb called Mucuna prureins was used as
115
+ an herbal dopamine supplement, and it played important role in improving the motor function and quality of
116
+ life of patients with PD [35].
117
+ However, the strong recommendations by previous studies for using yoga in PD have not been confirmed
118
+ with a well-designed and validated yoga module [31]. This study developed and validated an integrated yoga
119
+ module (IYM) for patients in the first three stages of PD (without comorbidities such as hypertension and
120
+ diabetes). The basic module was designed such that improvisations could be made according to the participant
121
+ requirements (e. g., if they require support or assistance).
122
+ Materials and methods
123
+ The IYM was developed as follows.

128
+ Step 1: Compilation of literature on PD
129
+ a. In this phase, we reviewed traditional [36, 37] and contemporary yoga texts [38–40].
130
+ b. Research papers on the use of yoga in neurological conditions, including modern scientific reviews of PD,
131
+ were identified using different search engines such as PubMed and Google Scholar. Indexing terms such as
132
+ “yoga,” “Parkinson’s disease,” “movement disorders,” “pranayama,” and “Hathayoga” were used in the
133
+ search. All experimental studies that only used yoga as the therapy for PD were included.
134
+ Step 2: Sorting the literature on PD
135
+ The compiled literature was searched to identify the common and unique features described in each study.
136
+ Studies published in scientific journals were extracted, which provided scientific support to the literary search.
137
+ Step 3: Preparing a yoga module based on previous literature on PD
138
+ A customized protocol was developed, which comprised practices supported by classical texts and research
139
+ evidence. This preliminary module comprised 28 practices.
140
+ Step 4: Validation of the yoga module by experts
141
+ For validation, the complete module was presented to yoga experts with clinical experience [who had either a
142
+ doctorate or Doctor of Medicine degree in Yoga, with a minimum of 5 years’ experience or a Masters degree
143
+ in yoga (MSc Yoga)/yoga therapist, with a minimum of 7 years’ experience]. These experts were requested to
144
+ validate the practices in the proposed module on a three-point scale as follows.
145
+ 1. Not essential: has no role in improving any symptoms or the quality of life of patients with PD
146
+ 2. Useful but not essential: useful in improving general wellbeing, but the benefits are not specific to PD symp-
147
+ toms
148
+ 3. Essential: very important for improving PD symptoms
149
+ A panel comprising 20 experts with the aforementioned qualifications was assembled for determining the con-
150
+ tent validity. Experts in yoga therapy with clinical experience (≥5 years) were also considered yoga experts.
151
+ Among the 20 experts, more than seven had previously applied yoga therapy in patients with PD and were
152
+ already using most of the practices included in this module. For calculating the content validity ratio (CVR),
153
+ the expert panel was asked to comment on the necessity of the included items.
154
+ The CVR for the total scale was computed based on the experts’ validation. According to Lawshe’s formula,
155
+ if more than half of the panelists indicate that an item is essential, then that item has the minimum content
156
+ validity. The CVR for our scale was ≥0.42, which was considered satisfactory for a panel of 20 experts.
157
+ Statistical analysis
158
+ The cut-offvalue of 0.42 was calculated by applying Lawshe’s formula for the CVR (Lawshe CH, 1975). The
159
+ mean CVR across the items may be used as an indicator of the overall test content validity.
160
+ Lawshe’s formula:
161
+ CVR = (Ne −N/2)
162
+ N/2
163
+ where
164
+ Ne = total number of panelists indicating “essential” for each practice
165
+ N = total number of panelists

426
+ Discussion
427
+ In the present study, we developed a valid yoga module for PD. We selected different yoga practices, including
428
+ loosening practices, breathing practices, yoga postures, and yoga-based relaxation and meditation techniques,
429
+ from classical yoga texts and previous research findings. Twenty qualified experts, who fulfilled the study
430
+ criteria, validated this module. Of the 28 practices subjected to validation, 21 had a CVR score of ≥0.49 and
431
+ were included in the final validated yoga module.
432
+ To date, no previous studies have focused on the validation of a yoga module for PD.
433
+ This study was conducted in two phases: (a) designing the yoga module for PD and (b) expert validation of
434
+ the module for PD.
435
+ In the first phase, the IYM was designed based on literature reviews of traditional textual references and
436
+ recent research publications. We did not find any direct references for yogic practices capable of improving
437
+ PD symptoms. However, recent Hatha yogic texts [41, 42] have increasingly emphasized on improving health
438
+ through different yogic practices.
439
+ In addition, recent findings on PD reported by several schools of yoga have helped in formulating a
440
+ yoga module for PD. The CVR was calculated for all 28 practices in our yoga module. Of these, 21 practices
441
+ (CVR≥0.42) were included in the validated yoga module (Table 3). The remaining seven practices (CVR≤0.42),
442
+ namely Tiger Breathing, Ardha Chakrasana (0.2), Tiger Breathing (0.2), Pashchimottanasana (0), Gomukasana
443
+ (0), Trataka (0.3), and Ujjayi Pranayama (0.4), were used as complimentary poses for important postures to align
444
+ the body and mind. These practices were slightly challenging for patients with PD at a beginner level.
445
+ Therefore, most experts did not consider them as essential for PD therapy. Apart from these seven practices,
446
+ the 21 practices were considered essential for PD therapy; thus, the final CVR satisfied the minimum value, as
447
+ per Lawshe’s CVR.
448
+ Similar to any other exercise protocol, an ideal yoga module consists of modes (types), frequencies, inten-
449
+ sities, durations, and progression. Determining the appropriate mode depends upon patient preference and
450
+ safety issues associated with the stage of PD or other conditions. The frequency, intensity, and duration are
451
+ specific to the type of activity and should be customized according to the patient’s ability to safely perform the
452
+ activity.
453
+ The loosening practices (Shithilikarna Vyayamas) included in this module helped in loosening the joints
454
+ and reducing the stiffness, which consequently helped in easy mobility.
455
+ The standing yoga asana (Ardhakti Chakrasana) helped in improving balance and strengthened the hip
456
+ extensor, quadriceps, hamstring, and calf muscles.
457
+ Other supine and prone postures helped in improving flexibility and strength and reducing the stiffness in
458
+ the back, hip, and lower limb muscles, thereby aiding mobility [27].
459
+ All relaxation techniques helped in reducing stress and anxiety and improving the relaxation of the body
460
+ and mind. This facilitated the improvement of anxiety, depression, and stress caused by PD [31].
461
+ Conclusions
462
+ The present IYM is a valid module for PD. However, future studies must determine the feasibility and efficacy
463
+ of the IYM.

+ Abstract:
19
+ Background: There exist controversies about the health effects of coconut. Fresh coconut consumption on hu-
20
+ man health has not been studied substantially. Fresh coconut consumption is a regular part of the diet for many
21
+ people in tropical countries like India, and thus there is an increasing need to understand the effects of fresh
22
+ coconut on various aspects of health.
23
+ Aim: To compare the effects of increased saturated fatty acid (SFA) and fiber intake, provided by fresh coconut,
24
+ versus monounsaturated fatty acid (MUFA) and fiber intake, provided by a combination of groundnut oil and
25
+ groundnuts, on anthropometry, serum insulin, glucose levels and blood pressure in healthy adults.
26
+ Materials: Eighty healthy volunteers, randomized into two groups, were provided with a standardized
27
+ diet along with either 100 g fresh coconut or an equivalent amount of groundnuts and groundnut oil for a pe-
28
+ riod of 90 days. Assessments such as anthropometric measurements, blood pressure, blood sugar and insulin
29
+ levels were performed before and after the supplementation period.
30
+ Results: Results of this study showed a significant reduction in fasting blood sugar (FBS) in both the groups.
31
+ However, a significant reduction in body weight was observed in the coconut group, while a significant increase
32
+ in diastolic pressure was observed in the groundnut group.
33
+ Conclusions: Results of this study suggest that fresh coconut-added diet helps reduce blood glucose levels and
34
+ body weight in normal healthy individuals.

38
+ Background
39
+ Many ancient philosophies on food and alternate therapies of medicine have enumerated multiple health bene-
40
+ fits of coconut [1, 2, 4]. However, medical research has associated coconut fats with dyslipidemia and increased
41
+ body weight, disturbed glucose metabolism and insulin resistance due to its rich saturated fat 92%% [5] and
42
+ saturated fatty acids (SFA) content [6]. All the above listed factors contribute to lifestyle disorders/noncom-
43
+ municable diseases (NCDs) which are major global health challenges of the twenty-first century. According to
44
+ latest data, out of 56 million deaths worldwide, 86%% are due to NCDs [7]. South Asians have a higher risk of
45
+ developing NCDs at a lower body mass index (BMI) and waist circumference (WC) than other ethnic groups
46
+ [8]. Hence, it is important to resolve the controversy surrounding coconuts which most Indians and Asians
47
+ consume every day, in either the fresh or dry form as an ingredient in their food as most traditional recipes de-
48
+ mand addition of fresh coconut. Studies on the effect of coconut oil consumption are contradictory, with some
49
+ showing deleterious effects [9–11] and others showing neutral effects [12, 13]. However, the available literature
50
+ on the health effects of fresh coconut on human subjects is too small and inconclusive. Fresh coconuts not only

+ contain SFA but are rich in fiber, protein, and a number of vitamins, minerals and electrolytes along with 40–50
61
+ % moisture [14]. Many studies report that increased consumption of fiber improves glucose metabolism, glu-
62
+ cose–insulin homeostasis, endothelial functioning and weight loss and also reduce inflammation [6, 15, 16]. On
63
+ the other hand, there are studies showing evidence that consuming SFA negatively affects the whole metabolic
64
+ profile by decreasing the particle size of high-density lipoprotein (HDL) and low-density lipoprotein (LDL),
65
+ increasing triglycerides and plasma glucose [11]. The present study evaluates the influence of daily consump-
66
+ tion of fresh coconut on anthropometry and physical and biochemical parameters in comparison to groundnut
67
+ which is rich in monounsaturated fatty acid (MUFA) in healthy adults.
68
+ Materials and methods
69
+ Subjects
70
+ The present study was carried out on 80 healthy adults who were recruited following advertisement of the
71
+ study within a residential university campus. Sample size was calculated using G-power 3.1.9.2 software us-
72
+ ing alpha = 0.05, power = 0.95 and effect size = 0.570. A sample size of (n = 27) in each group was obtained.
73
+ Healthy individuals between 18 and 40 years were recruited for the study. Accounting for possible dropouts,
74
+ 40 subjects were recruited for each group. Subjects were aged 23.8 ± 4.8 years and BMI 21.29 ± 2.07-kg/m2.
75
+ Subjects intolerant to nuts were excluded. Subjects were nonsmokers and were teetotalers. All subjects signed
76
+ a written consent to participate in the study and were free to withdraw at any time. The study protocol was
77
+ approved by the institutional ethics committee. The study was registered with Clinical Trial Registry of India
78
+ (CTRI/2016/07/007071).
79
+ Study design
80
+ The study was a randomized comparative study of 90-day duration. The subjects were randomized into two
81
+ groups – coconut group and groundnut group. The randomization was done using a computer-generated ran-
82
+ dom number table (www.randomizer.org). Subjects were trained and requested to abstain from consuming any
83
+ other food apart from the food and snacks provided by the coconut project kitchen, set up exclusively for the
84
+ study. Compliance to the diet was ensured by serving specific portion sizes for each individual based on their
85
+ calorie requirement and maintenance of individual log book.
86
+ Assessments
87
+ Anthropometry: Subjects’ weight and height were recorded by the same person on day 1 and day 90. Waist–hip
88
+ ratio (WHR) and BMI (weight in kg/height in meter squared) were determined. Body weight was measured
89
+ using a digital scale. Height, waist and hip circumference were measured using a standard measuring tape.
90
+ The systolic and diastolic blood pressures were recorded manually with a sphygmomanometer in lying-down
91
+ position.
92
+ Biochemical data and fatty acid analysis
93
+ Fasting blood sugar (FBS) was measured using fully automated Biochemistry Analyzer (Mindray BS-390,
94
+ China). Insulin was measured with commercially available human enzyme immunoassay ELISA kits (USCN
95
+ Biotech, Houston, Texas, USA) using Perkin Elmer Multimode plate reader (EnSpire, Waltham, Massachusetts,
96
+ USA).
97
+ Intervention
98
+ All subjects received a balanced diet and consumed this standard meal plus intervention for a period of 90
99
+ days. Along with the standard diet, the coconut group consumed 100 g of fresh coconut per day, while the
100
+ groundnut group consumed 45 g of groundnuts and 22 g of groundnut oil per day daily for a period of 90
101
+ days. A combination of groundnut and oil was used to make the two study interventions isocaloric, and to

257
+ Discussion
258
+ In the present study, an attempt was made to understand the impact of fiber and high SFA from fresh coconut
259
+ in comparison with fiber and fat (MUFA) from groundnuts when used in addition to a regular balanced meal.
260
+ Results of this study showed a significant decrease in body weight in the coconut group unlike the ground-
261
+ nut group. As early as 1987, Blundell et al. reported that fiber influences the body weight by influencing the
262
+ control over the food consumption [17]. Fiber brings about satiety and hence ensures reduced quantity of con-
263
+ sumption and reduces hunger for longer periods of time. This has been reported in many earlier studies [18–20].
264
+ Another study reported consuming >25 g of fiber per day may help to decrease the prevalence of obesity [20].
265
+ Mechanisms underlying this effect of fiber are due to a reduction in the energy density of the meal and prolong-
266
+ ing the intestinal phase of nutrient processing and absorption [18]. Another study reported that the effectiveness
267
+ of dietary fiber depends on the source and its chemical structure responsible for their physical properties [21].
268
+ Coconut has high insoluble dietary fiber of 58.71 % (63.25 % total dietary fiber) [22]. A food is considered to
269
+ be an “excellent source of fiber” if it contains 20 % of the recommended amount (5 g/serving) [23] and thus
270
+ we can call fresh coconut as an excellent source of dietary fiber. Coconut fiber shows highest water retention
271
+ and swelling capacity when compared to other dietary fibers [22]. But, the concern in increasing dietary fiber
272
+ is its negative effect on the bioavailability of minerals like calcium, iron, zinc and magnesium. This is due to the
273
+ property of dietary fiber to bind nonspecifically and reduce their absorption [24–26]. However, reports from
274
+ medium-chain fatty acid (MCFA)-rich diets showed increased absorption of calcium and magnesium [27]. Not
275
+ just fiber but also MCFA in coconut contributes to decrease in body weight. MCFAs in coconut oil contribute
276
+ to decrease in body weight [28] by increasing daily energy expenditure through increased rate of oxidation of
277
+ MCFA in liver. MCFA also induces satiety. Hormones including cholecystokinin, peptide YY, gastric inhibitory
278
+ peptide, neurotensin and pancreatic polypeptide have been proposed to the underlying mechanisms by which
279
+ MCFA may induce satiety; however, the exact mechanisms have not been established [29]. Another 4-week ran-
280
+ domized double-blind study reported a decrease in body weight and body fat and showed a sparing effect on
281
+ fat-free mass [30].
282
+ Higher intake of saturated fat adversely affects glucose metabolism and insulin resistance [6]. But, in our
283
+ study, high saturated fat content from fresh coconut did not have any negative effect on blood glucose. This is
284
+ possibly due to the presence of fiber and the MCFA in coconut. Many earlier studies on fiber have reported this
285
+ phenomenon [23, 31, 32]. Fiber-rich diets have proved to reduce glycosylated hemoglobin and day-long blood
286
+ glucose by 16 % [33, 34]. The effect of fiber on glucose metabolism can be attributed to slow absorption and
287
+ digestion of carbohydrates (slow gastric emptying), leading to a reduced demand for insulin [35] and improved
288
+ glycemic index of the diet [16, 36]. Another reason for lowering of FBS could be due to the coconut protein.
289
+ Coconut kernel protein has a potential effect in lowering the oxidative stress associated with diabetes, and this
290
+ was attributed to the presence of high amount of biologically potent arginine [37].
291
+ We also found trends of reduction in insulin levels in our study, although it was not significant. It is well
292
+ understood that hyperinsulinemia is most often caused by insulin resistance where pancreas tries to compen-
293
+ sate by making more insulin. Insulin resistance may eventually lead to the development of type 2 diabetes.
294
+ Similar results were seen in another study which reported decreased insulin with increased fiber intake [38].
295
+ MCFA also have been reported to have a positive impact on blood sugar and preserve insulin sensitivity by
296
+ suppressing fat deposition through enhanced thermogenesis and fat oxidation [39]. After a single oral dose of
297
+ MCFA, a slight hypoglycemia was observed way back in 1982 and was reported to be as a result of decrease in
298
+ the hepatic glucose output and increase in concentration of insulin. Insulin secretion seems to increase because
299
+ of stimulation of islets of Langerhans by either ketone bodies produced by MCFAs or MCFA themselves [27].
300
+ Obesity [40], inflammation and oxidative stress are attributed to the pathogenesis of cardiovascular diseases
301
+ including hypertension and atherosclerosis [41]. Consumption of fresh virgin coconut oil is reported to be ben-
302
+ eficial in preventing cardiovascular diseases by reducing body weight, insulin resistance, hypertension, total
303
+ cholesterol, triglycerides, phospholipids, LDL and very low-density lipoprotein (VLDL) levels, while improv-
304
+ ing HDL and antioxidant status [9, 40, 41]. Similarly, it also prevents lipid and protein abnormality, without
305
+ producing any detrimental effects on blood pressure and inflammatory biomarkers [41].

313
+ Coronary heart disease (CHD) is common in India and, recently, an increase in the incidence of CHD was
314
+ reported from the South Indian state of Kerala (literally known as “land of coconut palms”), where the people
315
+ consume a large amount of coconuts and coconut oil in their diet [12]. Consumption of coconut and coconut
316
+ oil that contains high amounts of saturated fats were believed to be strongly associated with high incidence of
317
+ CHD in Kerala. But, a case–control study revealed that there is no significant difference in coconut consumption
318
+ between CHD patients and age- and sex-matched healthy individuals [12]. This indicates that there is no specific
319
+ role for coconut or coconut oil in the causation of CHD of Indian patients from Kerala. Another study reported
320
+ that the intake of coconut, fruits and vegetables was negatively associated with hypertension in the urban
321
+ population of Trivandrum, Kerala, South India [42]. Presence of hyperlipidemia and heart diseases are reported
322
+ to be uncommon among high coconut-consuming populations [43].
323
+ India is facing an “epidemic” of NCDs resulting in substantial socioeconomic burden. Nutrition transition
324
+ over the past few decades coupled with declining levels of physical activity due to rapid urbanization have re-
325
+ sulted in escalating levels of obesity, dyslipidemia, subclinical inflammation, type 2 diabetes mellitus and CHD
326
+ in Indians. Hence, a preventive approach like consumption of fresh coconut might help in preventing the escala-
327
+ tion of NCDs in India [44]. Because, fresh coconuts are nutritious, which are not only rich in SFA, but also rich in
328
+ fiber, protein, vitamins, minerals, electrolytes and moisture. Interestingly, the composition of the SFA found in
329
+ the coconut consists of >50 % of MCFA, whose properties and metabolism differ from the long-chain SFA com-
330
+ monly found in animal products [40]. Moreover, it has been reported to have numerous medicinal properties
331
+ including antibacterial, antifungal, antiviral, antiparasitic, antidermatophytic, antioxidant [45], hypoglycemic
332
+ [45, 46], cytoprotective [46], hepatoprotective and immunostimulant [45]. Previous studies also support the ev-
333
+ idence that the consumption of coconut is effective in reducing body weight [40] and in improving increasing
334
+ beneficial effect in the treatment of obesity, dyslipidemia, insulin resistance and hypertension [47].
335
+ Strengths of the study: Daily consumption of fresh coconut has no negative impact on any markers discussed
336
+ in the paper and could reduce blood glucose and body weight. This impact might reduce the risk of developing
337
+ lifestyle disorders in healthy men and women. Moreover, this is one of the very few studies to report the effect
338
+ of coconut consumption in a raw and fresh form on blood glucose levels, when compared to most other trials
339
+ looking at the effect of coconut oil, and none of the subjects reported any adverse effect throughout the study
340
+ period. Limitations of the study: The present study was conducted in healthy individuals aged 23.8 ± 4.8 years;
341
+ thus, application of the results of this study either in elderly or in individuals with pathological conditions
342
+ is limiting the scope of the study. Hence, further studies are required in elderly and in various pathological
343
+ conditions for better understanding of the effect of fresh coconut intake.
344
+ Conclusions
345
+ Daily consumption of 100 g of fresh coconut, containing high levels of fiber and MCFA, is found to be beneficial
346
+ in reducing body weight and blood glucose levels and showed no significant negative impacts on biochemi-
347
+ cal, anthropometric and physical measures. Further research with larger sample size and long-term follow-up
348
+ including more specific parameters would throw better light in understanding the beneficial effects of fresh
349
+ coconut consumption.

27
+ Methods: The countrywide data was collected in 2017 in Individuals with high risk analysed
28
+ by Indian Diabetes Risk Score (IDRS) and self-declared diabetics were identified after
29
+ screening a sample of 240,968 individuals from rural (4 villages of about 500 adults each)

34
+ Results: In the age group of 31–34 years, the proportion of Diabetes (22.36%) and Prediabetes
35
+ (9.86%) was higher in comparison with younger age groups. Also, Diabetes (7.3%) and Pre-
36
+ diabetes (22%) were highest among those who had parental history of DM in both parents
37
+ as compared to those with Diabetes history in one parent [Diabetes (7.1%) or Prediabetes
38
+ (19.0%)] and no Diabetes Parental History (Diabetes (7.3%) and Prediabetes (18.3%) cases.

57
+ Introduction
58
+ Diabetes Mellitus affects people of all ages. There is a dra-
59
+ matic increase in the prevalence of Type 2 Diabetes (T2DM)
60
+ in young adults globally and also in India [1] which led to
61
+ increasing prevalence of long term complications of Diabetes
62
+ [2]. Almost 50% of the Indian population is unaware of their
63
+ Diabetes status [3].
64
+ Indian Diabetes Risk Score (IDRS) is often used as an ini-
65
+ tial, cost effective, simple tool to assess the risk of Diabetes
66
+ (T2DM) and it can also be used in combination with A1c
67
+ and BMI so that preventive measures can be taken at early
68
+ stages [1,4,5]. There are other scales similar to IDRS, like FIN-
69
+ RISK [6] and Framingham Offspring Diabetes Risk Score, Uni-
70
+ ted States [7], AUSDRISK [8] and many others [9] which are
71
+ used as an assessment tools in various countries for assess-
72
+ ment of T2DM risk. But IDRS is more specific for Indian pop-
73
+ ulation with sensitivity of 62.2% and specificity of 78.7% [10].
74
+ However Glycosylated Haemoglobin (A1c) is used as a gold
75
+ standard for detection of T2DM and Prediabetes [57,58]. It is
76
+ used in evaluation of the long term of glycemic control and
77
+ aids in prediction of risk for development of complication
78
+ associated with Diabetes. A1c level is known to have positive
79
+ correlation with age, gender, ethnicity, IDRS, BMI, and Waist-
80
+ hip ratio (WHR) [11,12]. Early identification of risk of T2DM
81
+ through IDRS can create an early awareness of the risk of
82
+ development of T2DM, which can be assured with A1c evalu-
83
+ ation. There is an increasing incidence of T2DM in adoles-
84
+ cents and young adults in countries like UK, USA, Japan and
85
+ Korea [25,61,62]. However very limited studies have focused
86
+ on the Young adult population with A1c assessment in India,
87
+ therefore, similar will provide an estimation about the distri-
88
+ bution of A1c levels among the Indian Young adults along
89
+ with the major risk factors contributing to this condition.
90
+ BMI, Lipid profile, Obesity are some risk factor’s which are
91
+ directly correlated with the development of T2DM [13–15],
92
+ hence assessment of these factors also gives an idea about
93
+ the glycemic control of the participant population. These fac-
94
+ tors along with enhanced A1c levels, also indicate involve-
95
+ ment of micro vascular diseases [16], which highlights the
96
+ need of lifestyle modification.
97
+ India’s T2DM prevalence has been expected to increase
98
+ upto 266% by 2030, with the urban population considered at
99
+ a higher risk than the rural population [17]. This highlights
100
+ an urgent need to highlight the importance of the need to
101
+ undertake lifestyle modification among young adults. For this
102
+ there is a dire need to adopt suitable public action so that the
103
+ enhanced burden of T2DM does not hurt health or develop-
104
+ ment budgets of developing countries. This is the first study
105
+ from India revealing a high prevalence of T2DM in young
106
+ adults based on both IDRS and A1c.The study calls for control
107
+ of A1c by nationwide public health intervention model.

109
+ Material and methods
110
+ 2.1.
111
+ Study population
112
+ The countrywide study was carried out in 2017 in which
113
+ house to house survey was carried out for screening of high
114
+ risk individuals in the community under the Niyantarita
115
+ Maduhmeha Bharat (NMB-2017, F.No.16-63/2016–17/CCRYN/RE
116
+ S/Y&D/MCT) multi cluster population based survey. The
117
+ detailed methodology is previously published [18,19].
118
+ This included various states and Union Territories of India.
119
+ Additionally, for the detection of high risk individuals from
120
+ the community, NMB screening form was used for collection
121
+ of data by Yoga Volunteers for Diabetes Mellitus (YVDMs).
122
+ The screening form contained information regarding the fol-
123
+ lowing parameters: Age, marital status, information about
124
+ Diabetes, Level of Physical activity, Genetic History, Anthropo-
125
+ metric parameters (consist of Weight, height, waist circum-
126
+ ference, Hip Circumference), socio-economic information
127
+ like education of Head of family, Occupation and Family
128
+ income/month etc. During the screening as well as at the
129
+ time of the registration, informed consents were obtained
130
+ from every participant.
131
+ The total number of 240,968 individuals were registered
132
+ with door to door visit out of which complete screening data
133
+ of 162,230 individuals was available. This screening was done
134
+ on the basis of IDRS i.e.  60 (High Risk). And 69,717 partici-
135
+ pants were invited for biochemical assessmentstelephoni-
136
+ cally. The total young adult population within the age range
137
+ (19–34 years) was 2862 (Male-1664, Female-1198).
138
+ The selected subjects were analyzed for biochemical and
139
+ anthropometric assessments. Further, the age was divided
140
+ into four age groups (4 equal intervals) i.e. 19–22, 23–26, 27–
141
+ 30 and 31–34 years.
142
+ 2.2.
143
+ Measures
144
+ IDRS was used to determine the level of risk for Diabetes
145
+ among Indian population. This was proposed by Mohan
146
+ et al. [24]. It is one of the most simple, cost effective and easy
147
+ technique to use for mass screening. It mainly uses four crite-
148
+ ria for detection of high-risk individuals from the community,
149
+ namely Age, Waist Circumference, Genetic History and Level
150
+ of Physical Activity of the subject. Further, the cumulative
151
+ scores of these four risk factors enables detection of risk sta-
152
+ tus (High risk  60, Moderate 30–50, low risk < 30) of the indi-
153
+ vidual. Diabetes (T2DM) is a condition characterized by high
154
+ blood sugar, insulin resistance and relative lack of Insulin
155
+ with A1c value  6.5 and Prediabetes is a condition where
156
+ blood sugar level is above normal but not as high as Diabetes
157
+ (5.7 - 6.4) [59,60].
158
+ The detailed procedure for biochemical assessments has
159
+ been previously published [18]. The BMI was calculated by
160
+ using the formula (of weight divided by height in squares)
161
+ and WHR was measured by using the formula waist divided
162
+ by hip (W/H).
163
+ 2.3.
164
+ Statistical analysis
165
+ The statistical analysis was carried out by using the SPSS
166
+ Statistics, version 22.0 (IBM Corp., Armonk, New York, United
167
+ States of America). For the assessment of data, continuous
168
+ data was given in the form of mean ± SD and n (%) was given
169
+ in as discrete categorical data; suitably matched percentiles,
170
+ range and median was used. Furthermore, for the assessment
171
+ of differences between actual and predicted A1cvalues paired

174
+ t-test was used. To analyze the normalcy of data, Kolmogorov
175
+ Smirnov test was used. In addition, to find out the relation-
176
+ ship among different parameters Spearman and Pearson
177
+ coefficient correlation test was administered. The appropriate
178
+ test i.e. Chi square or Fisher’s exact test was used as compar-
179
+ ison between different proportions. To find out independent
180
+ risk factors for different risk factors, Multivariate Regression
181
+ analysis was performed. Multivariate regression analysis
182
+ was used to predict the A1c levels in Young adult population
183
+ with perfect fitted model. The independent variables included
184
+ age, gender, family history, BMI, WHR and IDRS. The Age fac-
185
+ tor shows the higher significant value (0.000).

189
+ Clinical characteristics of participants
190
+ The data used in this study was collected under the National
191
+ Survey Niyantrita Madhumeha Bharat (NMB, 2017) program, a
192
+ national survey. The Table 1 shows the mean and SD values
193
+ of biochemical parameters in young adults. The data was
194
+ analyzed in four different groups: 19–22 years of age, 23–
195
+ 26 years, 27–30 years, and 31–34 years.
196
+ 3.2.
197
+ Distribution of age wise Diabetics and Pre diabetics
198
+ Based on A1c level estimates, the young adult population
199
+ included 7.2% Diabetic and 18.6% Pre Diabetics, which after
200
+ being categorized in age groups showed that 5.1% males
201
+ and 9.8% females were Diabetic, and 12.0% males 26.3%
202
+ females were pre diabetic. The age group categorization of
203
+ which is shown in Table 2.
204
+ There were more male young adults in the T2DM group
205
+ (12.8% in 31–34yrs) while there were more female young
206
+ adults in the Pre Diabetes range (23.7% in 31–34yrs) with
207
+ increasing age as shown in Table 2.Therefore, with growing
208
+ age, increased prevalence of diabetes in males was seen as
209
+ compared to females. In the Prediabetes group, it was found
210
+ to be higher in females.
211
+ 3.3.
212
+ Distribution of Diabetics and Pre-diabetics by A1c
213
+ The distribution of A1c among four age groups is shown in
214
+ Table 2. Based on A1c, the prevalence of T2DM and Predia-
215
+ betes increased with age. In the age group of 19–22 years,
216
+ the prevalence of T2DM was 5.3% and that for Prediabetes
217
+ was 13.0%. This further increases with the growing with age

+ viz: between the age groups of 23–26 years (Diabetes-4%,
219
+ Prediabetes-12.5%), 27–30 years (Diabetes-5.6%, Prediabetes-
220
+ 18.9%) and 31–34 years (Diabetes-9.9%, Prediabetes-22.4%)
221
+ respectively.
222

223
+ Role of family history in distribution of Diabetes and
224
+ Prediabetes on the basis of A1c
225
+ Parental diabetic history revealed that 7.7% of Diabetics and
226
+ 21% of Pre Diabetics were more associated with a Diabetic
227
+ father than a Diabetic mother. The proportion of Diabetes
228
+ (7.3%) and Prediabetes (22%) together with both Diabetic par-
229
+ ents was expectedly higher (Table 2). Furthermore, it was
230
+ found that Diabetic mother (10.0%) and father (9.1%) resulted
231
+ in a higher prevalence of Diabetic male young adults in com-
232
+ parison to female young adults (Father-6.9%, Mother-3.8%).
233
+ Additionally, age group, gender and family history wise differ-
234
+ ences are shown in Table 2.
235
+ 3.5.
236
+ Role of demography in distribution of Diabetes and
237
+ Prediabetes by A1c
238
+ Urban young adults were more prone to Diabetes (9.9%) and
239
+ Pre Diabetes in comparison to rural (5.1%) young adults at a
240
+ significant level.
241
+ 3.6.
242
+ Role of physical activity in distribution of Diabetes
243
+ and Prediabetes by A1c
244
+ Surprisingly, it was found that highest number of diabetes
245
+ (7.6%) and Prediabetes (18.7%) prevalence was found among
246
+ the moderate physical activity group in comparison with
247
+ the mild (Diabetes-7.4%,Pre Diabetes-17.5%) physical activity
248
+ group. Expectedly, the vigorous physical activity group had
249
+ lower incidence of Diabetes (5.1%), and Prediabetes (11.5%).
250
+ 3.7.
251
+ Role of biochemical parameters in distribution of
252
+ Diabetes and Prediabetes by A1c
253
+ According to A1c, 58.2% were Diabetics in the group with
254
+ PPBG (200) whereas 82.7% were pre diabetics in the normal
255
+ PPBG (<140 mg/dl) range. And 64.7% Diabetics were in the high
256
+ FBG range (125) and 69.9% pre diabetics were in the normal
257
+ FBG (<100 mg/dl) range. About 73.2% Diabetics and 80.3% Pre-
258
+ diabetics had normal cholesterol levels, whereas 51.9% of dia-
259
+ betic and 36.8% of prediabetic cases showed high risk triglyc-
260
+ erides levels.
261
+ However, 63.9% of women with low HDL were found to be
262
+ associated with Diabetes, 62.7% with Pre Diabetes in compar-
263
+ ison to the normal HDL range amongst which 36.1% were Dia-
264
+ betic and 37.3% were pre diabetics. In males, 69.4% were
265
+ Diabetic and 63.3% were pre diabetic in normal HDL level
266
+ group as compared to health risk category with 30.6% Diabetic
267
+ and 36.7% pre diabetic cases.
268
+ In case of LDL, the higher number of Diabetes (85.6%) and
269
+ Prediabetes (87.8%) cases were found in the normal category

1226
+ Discussion
1227
+ Diabetes is a complex disease and occurs due to cumulative
1228
+ effect of genetics and environmental factors like diet, dys-
1229
+ functional eating habits, levels of physical activity, levels of
1230
+ endocrine disrupting chemicals like arsenic and psychologi-
1231
+ cal stress. Worldwide, 451 million people have Diabetes and
1232
+ its prevalence is growing due to our stressful lifestyle and ever
1233
+ increasing intake of fast food rich in trans fats, sugars and
1234
+ salt. It occurs mainly due to insulin resistance and insuffi-
1235
+ cient insulin secretion and is predominantly caused due to
1236
+ oxidative stress and damage, inflammation and endoplasmic
1237
+ reticulum stress. Our study examined the distribution of A1c
1238
+ among 2862 Indian young adults along with other factors and
1239
+ biochemical parameters for the risk of T2DM.
1240
+ It was shown in a study that the occurrence of Diabetes in
1241
+ young adults could make them more vulnerable to other co-
1242
+ morbidities and poor quality of life, leading to unfavorable
1243
+ long-term outcomes thus raising the possibility of future pub-
1244
+ lic health calamity [1]. It has been found in many studies that
1245
+ younger onset of Diabetes leads to early development of other
1246
+ vascular complications than those with later onset [20]. Thus,
1247
+ simple lifestyle interventions like enhanced physical activity
1248
+ and Yoga may help to reduce the prevalence of this epidemic
1249
+ and its sequelae like cardiometabolic effects. One of the key
1250
+ factors which play a role in Diabetes type 2 onset is dysfunc-
1251
+ tional eating habits and stress. Yoga helps to regulate both
1252
+ and is known to enhance insulin sensitivity. As age is one
1253
+ the acknowledged risk factors for Diabetes, this is also true
1254
+ for young Indian adults. The proportion of young Diabetes
1255
+ and Prediabetes young adults has been found to increase with
1256
+ increase in the age [21] (Fig. 2A) Age is one of the risk factors
1257
+ for Diabetes and similar results were found in other studies
1258
+ [22]. T2DM prevalence also depends upon the ethnic back-
1259
+ ground, as described in various studies [12,23,24]. Further-
1260
+ more, it was found that male young adults had higher rate
1261
+ of Diabetes, with advancing age, is consistent with the study
1262
+ done by Seo et al in Korean population[25]. [25]. This study
1263
+ shows that proportionately more male were Diabetic in the
1264
+ age group 31–34 indicating that with advancing age male
1265
+ become more prone to Diabetes which is consistent with cer-
1266
+ tain studies Seo et al. [25–27]. Moreover, with advancing age,
1267
+ female also show some risk of development of Type 2 Dia-
1268
+ betes Mellitus as 23.7% females had Prediabetes in the age
1269
+ group of 31–34 years. However, the reason for more female
1270
+ subjects in Pre Diabetic group remains unclear. Fig. 3 shows
1271
+ the elevated values of A1c with age [28,29] among young male
1272
+ [30] adults. On the other hand, there were marginal gender
1273
+ differences between both genders on the A1c levels. The
1274
+ females had slightly higher A1c values than males (Fig. 2B).
1275
+ In this study, urban adults were found to have more Dia-
1276
+ betes and Pre Diabetes in comparison with rural adults.
1277
+ Higher physical activity and a diet rich in whole plant based
1278
+ foods, which is predominantly unrefined and unprocessed,
1279
+ could account for the lower prevalence of Diabetes in rural
1280
+ Indians. A study by Mohan et al has also reported the preva-
1281
+ lence of self-reported Diabetes to be higher in urban areas
1282
+ [31]. Presence of more diagnostic facilities in urban setup
1283
+ could further explain higher prevalence of self-reported Dia-
1284
+ betes amongst urban Indians. However, a study done by
1285
+ Anjana et al. revealed that prevalence of Diabetes and
1286
+ Prediabetes was equally high in
1287
+ both rural and urban
1288
+ localities [32].
1289
+ Table 4 describes the prediction values of A1c based on
1290
+ multivariate regression model and shows the significant asso-
1291
+ ciation of Parental history with A1c. Furthermore, the propor-
1292
+ tion of Diabetes and Prediabetes has been found to be more
1293
+ among those young adults who had both parents as Diabetics.
1294
+ This suggests that there is higher risk of Diabetes when both
1295
+ parents are affected. In addition, it has been found that dia-
1296
+ betic father had higher probability of having diabetic kids in
1297
+ comparison with diabetic mother. However, contradictory
1298
+ results were found in another study where Diabetes was more
1299
+ prevalent in the case of Diabetic mother than father [33].
1300
+ Additionally, it was also found that sons are more prone to
1301
+ Diabetes if any of the parents from Diabetes, in comparison
1302
+ with their daughters. On the other hand, some studies
1303
+ described association of Diabetes among fathers and their
1304
+ Diabetic sons [34,35]. Diabetes is a complex disease and thus
1305
+ no role of holandric inheritance to account for higher
1306
+ prevalence in sons of Diabetic fathers. However, abdominal
1307
+ obesity with higher levels of abdominal fat (visceral fat-
1308
+ mesentric and omental fat) plays a critical role in etiopatho-
1309
+ genesis of metabolic syndrome and Diabetes. Dysregulation
1310
+ in lipids and glucose are associated with visceral adiposity
1311
+ rather than subcutaneous fat accumulation. Accumulation
1312
+ of visceral fat shows a positive correlation with levels of C
1313
+ peptide, insulin and glucose levels but Testosterone levels
1314
+ show negative association. Although Diabetes is not a risk
1315
+ factor for hypogonadism, it is associated with lower levels
1316
+ of testosterone. In women too, insulin and C peptide levels

1324
+ While ovulation, clinical or biochemical hyperandrogenism,
1325
+ polycystic ovaries and insulin resistance are the hallmarks
1326
+ of polycystic ovarian disease (PCOD) these women have a
1327
+ higher susceptibility to develop T2DM and gestational Dia-
1328
+ betes. It affects 4–7% of pregnancies and is characterized by
1329
+ carbohydrate intolerance at onset of pregnancy. Women with
1330
+ PCOD have higher pre-gestational levels of insulin and
1331
+ develop derangements of glycemic control during this time
1332
+ despite increased levels of insulin due to placental hormones.
1333
+ This could lead to hyperglycemia and gestational Diabetes. It
1334
+ has been found in a study that the family history of T2DM is
1335
+ inversely related with age. This implies that those having
1336
+ strong family history of Diabetes have earlier onset of Dia-
1337
+ betes Weerarathna and Dissanayake [36]. A strong family his-
1338
+ tory increases susceptibility to develop Diabetes if there is
1339
+ sedentary lifestyle and dysfunctional eating habits.
1340
+ The levels of FBG and PPBG were found increased in Dia-
1341
+ betics and Prediabetes. The PPBG Diabetes (200) and FBG
1342
+ Diabetes (125) constituted more Diabetes cases when fur-
1343
+ ther analyzed by A1c, showing higher correlation between
1344
+ A1c and other biochemical parameters. Specifically, 58.2% of
1345
+ participants with PPBG  200 were found to be T2DM as per
1346
+ A1c criteria. This could be ascribed to inconsistencies in cor-
1347
+ relation between PPBG and A1c. Several studies have shown a
1348
+ strong correlation of PPBG and FBPG Weerarathna and Dis-
1349
+ sanayake [36,37]. Biochemical analysis has also revealed that
1350
+ individuals with normal cholesterol and LDL levels may also
1351
+ develop Diabetes and Prediabetes. Raised Triglycerides are
1352
+ also health risks with strong association with Diabetes. Dys-
1353
+ lipidemia is one of the major co morbidity associated with
1354
+ insulin resistance characterized by increased plasma triglyc-
1355
+ erides concentration, decreased HDL increased LDL concen-
1356
+ tration [38]. Abnormal lipids in Diabetes patients include
1357
+ elevated VLDL, LDL and Triglycerides and reduced levels of
1358
+ HDL, low levels of HDL levels in T2DM patients. This is almost
1359
+ double as compared to non-diabetics [39]. In our study, it was
1360
+ found that the young female adults with low HDL levels were
1361
+ found prone to Diabetes and Prediabetes (who had health
1362
+ risk). In contrast, Diabetics and Prediabetics males had nor-
1363
+ mal HDL levels.
1364
+ The result of the study showed that Obesity is the one of
1365
+ the contributing factors for Diabetes (11.4%) and Prediabetes
1366
+ (28.1%). Moreover, obesity is a major factor for the develop-
1367
+ ment of insulin resistance. According to WHO, obesity in
1368
+ childhood and adolescence increases at a higher rate in devel-
1369
+ oping countries of Asia and Africa [40]. Association between
1370
+ abdominal obesity and Diabetes has also been reported in
1371
+ number of studies [41–43]. The prevalence of Diabetes and
1372
+ Prediabetes was found reduced among vigorous exercise
1373
+ group in our study [44–46].There is a marginal difference in
1374
+ diabetic cases among the mild (7.4%) and moderate (7.6%)
1375
+ physical activity group. Apart from the level of physical activ-
1376
+ ity, there are various factors which contribute to Diabetes.
1377
+ This includes the dietary pattern. Although the current litera-
1378
+ ture [47] is consistent with moderate exercise group to have
1379
+ low propensity to develop Diabetes as compared to mild exer-
1380
+ cise group [48], we report this finding to be not significantly
1381
+ different. Regardless, mild physical activity is also effective
1382
+ in improving glycemic parameters [49].
1383
+ The strength of the study derived from the unique applica-
1384
+ tion of A1c for prediction and distribution of Diabetes among
1385
+ young adults is hitherto unreported from India. Also, there
1386
+ are very few studies available on the basis of A1c. This may
1387
+ be due to high costs associated with this test. This is the first
1388
+ study from India which represents 24 states and 2 union ter-
1389
+ ritories and 5 zones to analyze the status of Diabetes and
1390
+ Prediabetes in Indian young adults. Therefore, this study
1391
+ paves way to understand the risk of Diabetes in young adults
1392
+ and suggests timely management and prevention of the
1393
+ same. The limitation that it does not take into account indi-
1394
+ viduals below an age of 19 years can be addressed in future
1395
+ studies. Furthermore, physical inactivity group were not
1396
+ included in the study. Psychological stress also plays a major
1397
+ role in etiology of T2DM but Psychological assessments,
1398
+ socioeconomic status (like family income and parental educa-
1399
+ tion) were not incorporated in this study.
1400
+ The present study describes the glycosylated A1c levels
1401
+ from a large cohort of individuals sampled equally across
1402
+ urban and rural areas from India, and also highlights the util-
1403
+ ity of IDRS for identifying individuals at high risk for T2DM
1404
+ which correlate to these levels. The results from the current
1405
+ study highlights a high prevalence of T2DM in young Indian
1406
+ adults which indicates the need of lifestyle modification
1407
+ [41,50] in order to halt or delay the onset of Diabetes among
1408
+ in Young adults. Thus, it is imperative to institute public
1409
+ health measures like exercise and Yoga [51,52–54] along with
1410
+ dietary modifications [55,56]. We also recommend a similar
1411
+ analysis on regular intervals in order to understand the
1412
+ changing patterns of A1c among the community.

+ Abstract
24
+ Objective:
25
+ Thoracic radiotherapy (TRT) may result in toxicities that are associated
26
+ with performance declines and poor quality of life (QOL) for patients and their family
27
+ caregivers. The purpose of this randomized controlled trial was to establish feasibility
28
+ and preliminary efficacy of a dyadic yoga (DY) intervention as a supportive care strategy.
29
+ Methods:
30
+ Patients with stage I to III non‐small cell lung or esophageal cancer under-
31
+ going TRT and their caregivers (N = 26 dyads) were randomized to a 15‐session DY or
32
+ a waitlist control (WLC) group. Prior to TRT and randomization, both groups com-
33
+ pleted measures of QOL (SF‐36) and depressive symptoms (CES‐D). Patients also
34
+ completed the 6‐minute walk test (6MWT). Dyads were reassessed on the last day
35
+ of TRT and 3 months later.
36
+ Results:
37
+ A priori feasibility criteria were met regarding consent (68%), adherence
38
+ (80%), and retention (81%) rates. Controlling for relevant covariates, multilevel modeling
39
+ analyses revealed significant clinical improvements for patients in the DY group com-
40
+ pared with the WLC group for the 6MWT (means: DY = 473 m vs WLC = 397 m,
41
+ d = 1.19) and SF‐36 physical function (means: DY = 38.77 vs WLC = 30.88; d = .66)
42
+ and social function (means: DY = 45.24 vs WLC = 39.09; d = .44) across the follow‐up
43
+ period. Caregivers in the DY group reported marginally clinically significant improve-
44
+ ments in SF‐36 vitality (means: DY = 53.05 vs WLC = 48.84; d = .39) and role perfor-
45
+ mance (means: DY = 52.78 vs WLC = 48.59; d = .51) relative to those in the WLC group.
46
+ Conclusions:
47
+ This novel supportive care program appears to be feasible and bene-
48
+ ficial for patients undergoing TRT and their caregivers. A larger efficacy trial with a
49
+ more stringent control group is warranted.

+ BACKGROUND
56
+ Thoracic radiotherapy (TRT), particularly when delivered concurrently
57
+ with chemotherapy, may result in acute and late toxicities (eg,
58
+ dyspnea, reduced lung function).1-4 Chemoradiation is often the
59
+ definitive treatment for patients with thoracic malignancies (eg, lung
60
+ and esophageal cancers) because they tend to be diagnosed with
61
+ unresectable, locally advanced or even metastatic disease.5 Due to

70
+ the adverse effects of aggressive multimodal cancer treatment, a gen-
71
+ erally poor prognosis, and common comorbidities, patients with tho-
72
+ racic cancers are at high risk of experiencing physical function
73
+ declines, physical and psychological symptoms, and overall poor qual-
74
+ ity of life (QOL).3,4,6 Consequently, patients have a high need for tan-
75
+ gible care and emotional support from their families.7 Caregiving is
76
+ taxing, however, and family caregivers often report feeling helpless
77
+ and overwhelmed and having low caregiving efficacy.8,9 Given the
78
+ high rates of distress in both cancer patients and their family care-
79
+ givers, and the interdependent nature of distress in families coping
80
+ with cancer, a dyadic approach to supportive care may be advanta-
81
+ geous
82
+ over
83
+ traditional,
84
+ patient‐oriented
85
+ interventions.10-12
86
+ The
87
+ psychosocial literature includes reports of a handful of dyadic
88
+ randomized controlled trials (RCTs) including those with lung and
89
+ esophageal cancer patients, with two of these trials providing
90
+ evidence of preliminary efficacy in improved psychological distress
91
+ or relationship outcomes.13,14 Of note, previously reported dyadic
92
+ psychosocial interventions have not targeted physical function as a
93
+ study outcome.
94
+ Considering the need to address physical decline and the mixed
95
+ evidence regarding improved symptoms and QOL in thoracic cancer
96
+ patients and their caregivers, a dyadic yoga (DY) intervention that
97
+ integrates gentle movements with breathing exercises and relaxation
98
+ techniques focusing on the needs of the patient‐caregiver dyad may
99
+ be a promising supportive care strategy. Although researchers have
100
+ extensively studied yoga in women with breast cancer, little is known
101
+ regarding the feasibility of implementing an RCT of yoga in patients
102
+ undergoing TRT.15,16 In our formative research, we developed a DY
103
+ intervention to improve QOL during and after TRT.17
104
+ Building on this previous study, we sought to examine the feasibil-
105
+ ity of implementing an RCT of this intervention and expand our proce-
106
+ dures to include the 6‐minute walk test (6MWT), an objective,
107
+ clinically relevant measure of patients' physical function found to pre-
108
+ dict survival in patients with lung cancer.18 Based on previous dyadic
109
+ psychosocial RCTs, we hypothesized that at least 60% of eligible
110
+ dyads would consent to participate, participants randomized to the
111
+ DY group would attend at least 75% of the intervention sessions,
112
+ and 60% of the dyads would be retained at the 3‐month follow‐up
113
+ assessment.13,14,19 Additionally, we sought to establish the preliminary
114
+ efficacy for the intervention regarding clinically significant improve-
115
+ ments in patients' 6MWT results and patients' and caregivers' depres-
116
+ sive symptoms and overall QOL relative to those of dyads in a waitlist
117
+ control (WLC) group at the end of treatment and 3 months later.

124
+ Patients with stage I to IIIB non‐small cell lung or esophageal cancer
125
+ undergoing at least 5 weeks of TRT having a consenting family care-
126
+ giver (eg, spouse, sibling, adult child) were eligible to participate. Both
127
+ patients and caregivers had to be at least 18 years old, proficient in
128
+ English, and able to provide informed consent. Patients were excluded
129
+ if they were not oriented to time, place, or person; practiced any form
130
+ of yoga on a regular basis (self‐defined) in the year prior to diagnosis;
131
+ and had a physician‐rated Eastern Cooperative Oncology Group
132
+ (ECOG) performance status of greater than 2.

135
+ Procedure
136
+ Prior to starting the trial, the MD Anderson Institutional Review Board
137
+ approved all of the procedures. Research staff identified potentially
138
+ eligible patients
139
+ in the institution's
140
+ electronic
141
+ medical
142
+ records,
143
+ approached patients and caregivers during routine clinic visits, con-
144
+ firmed their study eligibility, and obtained their written informed con-
145
+ sent to participate prior to data collection. If a caregiver was not
146
+ present during a clinic visit, the patient's permission to contact the
147
+ caregiver was obtained. Prior to randomization, both patients and
148
+ caregivers completed paper‐pencil survey measures (baseline/T1)
149
+ and then again on the last day of TRT (T2), and 3 months later (T3).
150
+ Surveys were returned either in person during a clinic visit or via
151
+ pre‐postage paid return envelops. Patients also completed the
152
+ 6MWT at T1 to T3. Participants were enrolled for a duration of 18
153
+ to 20 weeks. The trial was completed between November 2014 and
154
+ October 2016.

157
+ Randomization
158
+ Dyads were randomized to either the DY or WLC group through a
159
+ form of adaptive randomization called minimization ensuring that the
160
+ groups were balanced on patients' stage, sex, age, and cancer type
161
+ (non‐small cell lung cancer [NSCLC] vs esophageal cancer) using a
162
+ computerized system (Filemaker).20

165
+ DY group
166
+ The manualized yoga program was developed in collaboration with
167
+ Swami Vivekananda Yoga Anusandhana Samsthana. Two certified
168
+ instructors (International Association of Yoga Therapists; C‐IAYT)
169
+ who had also completed a 200‐hour instructor course in Vivekananda
170
+ yoga implemented the sessions. All sessions were delivered to individ-
171
+ ual patient‐caregiver dyads either in a designated space for behavioral
172
+ interventions or a family consult room in the radiation treatment area
173
+ based on participants' preference. Dyads had to attend all sessions
174
+ together over the course of patients' standard TRT (2‐3 times per
175
+ week for a total of 6 weeks; 60 minutes per session).
176
+ The program consisted of four main components: (1) joint
177
+ loosening with breath synchronization; (2) postures (asanas) including
178
+ partner‐poses
179
+ followed
180
+ by
181
+ relaxation
182
+ techniques;
183
+ (3)
184
+ breath
185
+ energization (pranayama) with sound resonance; and (4) guided
186
+ imagery/meditation focusing on dyadic concepts (eg, love, accep-
187
+ tance).17 Sessions 1 to 4 focused on gradually introducing the various
188
+ practices. The remaining sessions (5‐15) focused on practicing the
189
+ components and answering questions pertaining to the techniques
190
+ and participants' experiences. Starting with session 1, instructors con-
191
+ veyed the notion that each practice is intended to target the needs of
192
+ both members of the dyad, with a focus on their interconnectedness.

+ Measures
212
+ Demographic and medical factors. Demographic items (eg, age, marital
213
+ status) were included in the baseline questionnaires. Patients' medical
214
+ data were extracted from their electronic medical records.
215
+ Feasibility data. Tracking data regarding consent rates, class atten-
216
+ dance, completion of questionnaires, and attrition were kept. Partici-
217
+ pants in the DY group completed an evaluation of the intervention
218
+ to assess their satisfaction. The frequency of home yoga practice
219
+ was assessed weekly with a paper‐pencil practice log over the course
220
+ of TRT. Instructors monitored for adverse events, and participants
221
+ completed perceived exertion during the yoga session on the 0 to
222
+ 10 Borg scale on a weekly basis to ascertain patient safety.21
223
+ Patient physical function was assessed using the 6MWT following
224
+ the guidelines of the American Thoracic Society (ATS).22 A research
225
+ assistant who was blinded to group assignment implemented the tests
226
+ on a straight, long, and flat hospital corridor. For patients with thoracic
227
+ malignancies, 42 meters (m) has been identified as the cut‐off value
228
+ for clinically relevant differences.23 Patients were asked to indicate
229
+ their level of perceived exertion during the task on the 0 to 10 Borg
230
+ scale and their shortness of breath on the 0 to 10 modified Borg
231
+ Scale.21,24 A 1‐point between‐group difference has been identified
232
+ as the minimally clinically important difference.25
233
+ Depressive symptoms were assessed using the Center for Epidemi-
234
+ ologic Studies‐Depression Scale (CES‐D), a 20‐item self‐reported
235
+ instrument focusing on the affective component of depression.26 A
236
+ score of at least 16 is the cutoff for further psychological evaluation
237
+ for a depressive disorder.
238
+ QOL was assessed with the Medical Outcomes Study 36‐item
239
+ short‐form survey (SF‐36) assessing eight distinct domains: physical
240
+ functioning, physical impediments to role functioning, bodily pain,
241
+ general health perceptions, vitality, social functioning, emotional
242
+ impediments to role functioning, and mental health.27 A group
243
+ difference of 5 points is considered clinically significant.

246
+ Statistical analyses
247
+ To examine feasibility, we calculated descriptive statistics of consent,
248
+ class attendance, assessment completion, and program satisfaction.
249
+ To establish preliminary efficacy, we used an intent‐to‐treat analysis
250
+ when performing multilevel modeling (MLM) using PROC MIXED
251
+ (SAS, 9.4 version). We used separate analyses for patients and
252
+ caregivers and controlled for baseline level of the given outcome.
253
+ Because age, gender, smoking status, and patients' stage at diagnosis
254
+ have been associated with outcomes in thoracic cancers,28,29 we
255
+ included these factors as a priori covariates when examining group
256
+ means. In the caregiver models, we controlled for age and sex as they
257
+ were associated with the outcomes at P < .05. We examined each
258
+ dimension of the SF‐36 separately to identify which QOL domain
259
+ may serve as a primary outcome in the future efficacy trial. Because
260
+ the current study is a pilot trial and not adequately powered, we
261
+ interpreted least square mean (LSM) differences for the 6MWT and
262
+ SF‐36 domains based on clinical relevance as opposed to inferential
263
+ significance testing. We also calculated the effect size (Cohen's d)
264
+ associated with each between‐group comparison interpreting effects
265
+ as small (d = .2), medium (d = .5), and large (d = .8) and recorded 95%
266
+ confidence intervals (CI).30 Because too few participants met the
267
+ CES‐D caseness criterion, we did not examine change in caseness
268
+ to identify clinical relevance. Instead, we examined the between‐
269
+ group effect size to establish preliminary efficacy. We followed up
270
+ the MLM analyses with cross‐sectional between group tests to
271
+ examine LSM for time point. We determined sample size based on
272
+ Whitehead et al's recommendation of n = 30 for a two arm‐pilot
273
+ trial detecting a medium effect size with 90% power and two‐sided
274
+ 5% significance.31 (We consented an additional two dyads because
275
+ two of the consented patients became ineligible as mentioned
276

+ Recruitment and sample retention
300
+ We screened 144 patients, 47 of whom were eligible for study

+ participation. Ineligibility was mainly due to lack of a caregiver or
302
+ consenting caregiver (n = 73). Of the eligible dyads, 32 (68%)
303
+ consented. Refusal reasons were lack of interest (n = 7) and time
304
+ (n = 5), feeling too sick or distressed to participate (n = 2), and not
305
+ wanting to risk being in the control group (n = 1). Four patients

491
+ CONCLUSIONS
492
+ The goal of this pilot RCT was to demonstrate the feasibility and pre-
493
+ liminary efficacy of a DY intervention for patients undergoing TRT and
494
+ their family caregivers, targeting patient physical function and patient
495
+ and caregiver depressive symptoms and QOL. The results revealed
496
+ that the trial was feasible, as it met our a priori feasibility criteria
497
+ regarding consent, retention, and adherence rates. Of note, 80% of
498
+ the dyads attended all 15 DY sessions, which is remarkable consider-
499
+ ing that the majority of the patients had stage III disease and were
500
+ undergoing aggressive chemoradiation. All of the patients and care-
501
+ givers considered the intervention to be useful and beneficial, which
502
+ they further demonstrated by their yoga practice outside of class.
503
+ Based on clinically significant improvements in objective and self‐
504
+ reported measures, the DY program may be efficacious in improving
505
+ patients' physical function. We also observed clinically significant
506
+ improvements in patients' social function across the 3‐month follow‐
507
+ up period and short‐term clinically significant gains in the role perfor-
508
+ mance and mental health domains as well depressive symptoms. The
509
+ caregivers' treatment response was less pronounced than that of the
510
+ patients. Although we found no role differences at baseline regarding
511
+ depressive symptoms, unlike patients, caregivers in the DY group did
512
+ not show improvements across the follow‐up period. Regarding
513
+ QOL, effect sizes for caregivers ranged from small to medium, with
514
+ marginal clinically significant improvements in vitality and role perfor-
515
+ mance, two important aspects of QOL that are relevant to providing
516
+ quality care and support to patients.
517
+ Based on these findings, an efficacy RCT is warranted. Although
518
+ the current feasibility trial has provided an essential foundation for
519
+ evaluating the effects of a dyadic supportive care approach, remaining
520
+ crucial issues must be addressed in future research. For example,
521
+ whether a dyadic intervention is in fact superior to a patient‐only
522
+ approach in general and in this particular patient population is unclear.
523
+ Although caregivers' responsiveness to the dyadic intervention was
524
+ modest and thus may not appear to provide a strong rationale for a
525
+ dyadic intervention, the larger intervention context must be consid-
526
+ ered. Enrolling patients and caregivers jointly may increase feasibility
527
+ with regard to consent and adherence rates as demonstrated herein
528
+ and in the behavior change literature.32,33 Without the support of a
529
+ MILBURY ET AL.
530
+ 619
531
+ family caregiver, a patient may be less likely to attend yoga sessions
532
+ and practice it at home, which may compromise treatment efficacy.
533
+ Moreover, patients indicated that they enjoyed and preferred partici-
534
+ pating with their family members, which may account for the clinically
535
+ significant improvements in social function we observed. Our next
536
+ study will include qualitative interviews and pinpointed measures to
537
+ examine the relationship constructs (ie, illness communication) as a
538
+ potential intervention mechanism. Also, given the interdependence
539
+ of depressive symptoms and QOL, even small treatment effects on
540
+ caregivers may have systemic implications and, thus, optimize patients'
541
+ responses.
542
+ Nevertheless, several patients were ineligible for the present
543
+ study because they lacked family caregivers who were able to partic-
544
+ ipate, which may potentially limit external validity and feasibility of a
545
+ larger trial. To remedy these concerns, we propose the use of video-
546
+ conferencing delivery, which we are currently testing. As opposed to
547
+ one primary caregiver, enrolling alternate caregivers who attend only
548
+ a subset of sessions may also increase patient eligibility. Regarding
549
+ the caregivers, their treatment responses may have been limited
550
+ because their primary focus may have been supporting patients as
551
+ opposed to practicing self‐care. Although caregivers' consent and
552
+ retention rates tend to be much higher in dyadic intervention studies,
553
+ they may receive greater benefit from caregiver‐only interventions,
554
+ possibly offering respite from their caregiving. Head‐to‐head compar-
555
+ isons of dyadic and individual‐oriented supportive care are needed to
556
+ address these central issues in the dyadic intervention literature.34
557
+ Future research is also needed to explore the underlying mecha-
558
+ nisms of yoga, particularly DY, as in the present study. For patients
559
+ undergoingTRT, breathing exercises targeting dyspnea, a common side
560
+ effect, may be a primary mechanism by which yoga protects patients
561
+ from physical function declines during and after TRT. In fact, patients
562
+ in the DY group reported significantly less severe dyspnea and per-
563
+ ceived less exertion during the 6MWT than did patients in the WLC
564
+ group. Moreover, examining improvements in dyadic coping or illness
565
+ communication may also be important mediators to be considered.

568
+ Study limitations
569
+ In addition to lacking an active control group, our study is limited by
570
+ the sample's fairly homogenous characteristics. Patients and care-
571
+ givers were psychologically well‐adjusted based on the rather low
572
+ mean CES‐D scores, so how patients and caregivers with greater dis-
573
+ tress would fare with the DY intervention is unclear. Again, an efficacy
574
+ trial with a larger sample is needed to facilitate subgroup analyses and
575
+ identify participant characteristics associated with differential treat-
576
+ ment responses. Lastly, the pilot RCT was not powered to examine
577
+ group differences and the initial evidence for efficacy presented here
578
+ must be interpreted with caution.

+ Clinical implications of the utility of this intervention in the clinical
583
+ setting are premature at this point. However, the present pilot RCT
584
+ provides strong evidence of the feasibility of the DY intervention for
585
+ patients undergoing TRT and their family caregivers based on a priori
586
+ criteria pertaining to DY consent, adherence, and retention ratings.
587
+ Patients and caregivers rated the intervention as beneficial and useful.
588
+ Using clinical cutoff scores, we demonstrated preliminary DY efficacy
589
+ regarding patients' QOL and. Objectively measured physical function.
590
+ Thus, the intervention has promise in protecting patients against
591
+ TRT‐related toxicities. Based on these findings, a large, well‐controlled
592
+ efficacy trial of DY is warranted.

+ Dear Dr. Telles:
100
+
101
+ This PDF contains the edited manuscript and a copy of the proof of your paper, “Effect of four voluntarily
102
+ regulated yoga breathing techniques on grip strength.”
103
+
104
+ Please read the proof carefully. Author’s corrections are charged to the author. This refers to any changes in
105
+ the copy which are not due to printer’s error. Such changes are expensive and increase the time necessary for
106
+ handling.
107
+
108
+ You will receive 50 preprints without covers. If you wish to order additional preprints or covers, please fill in
109
+ the amounts of each on the enclosed form. Be sure to indicate the correct mailing address for the preprints.
110
+
111
+ Please note that we were able to get the piece into an 8-page signature rather than the estimated 12 pages.
112
+ Please advise us whether you wish the $110.00 credit to be returned to you, held until you wish to publish a
113
+ paper in the future, or applied to additional reprints or covers. Note that in the 8-page signature you will have
114
+ one blank page which you may use in the future by submitting a 1- to 2-page note-sized manuscript.
115

315
+ Summary.—Bilateral hand-grip strength was studied in 21 male volunteers (M
316
+ age = 25.6 yr., SD = 5.2). All were assessed before and after five practice sessions of
317
+ 20 min. duration: right-nostril yoga breathing, left-nostril yoga breathing, alternate-
318
+ nostril yoga breathing, breath awareness, and a no-intervention session. Data were
319
+ analyzed with analyses of variance and an analysis of variance using the no-breath
320
+ awareness control condition as a covariate. There were no significant changes. The
321
+ left-hand-grip strength reduced after left-nostril yoga breathing. However, findings
322
+ were not considered significant, so methodological issues in yoga research which
323
+ could contribute to null findings and even mask actual changes were discussed.
324
+ The basic-rest-activity cycle (BRAC) was initially described based on
325
+ observations made for infants and was later shown also to hold for adults
326
+ (Kleitman, 1963). Various physiological processes are entrained to this
327
+ rhythm. One of the lesser known is the nasal cycle.
328
+ The nasal cycle is an ultradian rhythm during which both nostrils
329
+ are alternately patent. Originally, the periodicity was reported to range
330
+ between 2 and 8 hours. (Keuning, 1968). However, time analyses detect­
331
+ ed periods for the nasal cycle and coregulated systems. These periods
332
+ were at 280–300, 215–275, 165–210, 145–160, 105–140, 70–100, and 40–65
333
+ minutes, with the greatest spectral power in longer periods during wak­
334
+ ing (Shannahoff-Khalsa, Kennedy, Yates, & Ziegler, 1996, 1997). While
335
+ the nasal cycle is coupled to other rhythms such as alternating cerebral
336
+ hemispheric dominance and autonomic activity, it has also been sug­
337
+ gested that right nostril dominance may correlate with the activity phase
338
+ of the basic-rest-activity cycle (Werntz, Bickford, Bloom, & Shannahoff-
339
+ Khalsa, 1983; Shannahoff-Khalsa, 2008).
340
+ A very early description by Wada, in 1922, presented a relation be­
341
+ tween basic rhythms (i.e., hunt-eat-rest) and hand-grip strength (Shanna­
342
+ hoff-Khalsa, 1991; Shannahoff-Khalsa, 2008). Hand-grip strength is used
343
+ to assess general strength, and hence, underlies work capacity, extent of
344
+ injury and disease, and the possibility of rehabilitation (Petersen, Petrick,
345
+ Connor, & Conklin, 1989). Motor activity during wakefulness showed
346
+ greater hand-grip strength during periods of hunger contractions than for
347
+ quiescent or postmeal periods. This rhythm, i.e., hunt-eat, then rest, may
348
+ be considered another way of viewing the basic-rest-activity cycle. Given

355
+ this connection between basic-rest-activity cycle and hand-grip strength
356
+ and the speculation that right nostril breathing corresponds to the activity
357
+ phase of the basic-rest-activity cycle, the effect of uninostril breathing on
358
+ hand-grip strength has been studied in yoga practitioners (Raghuraj, Nag­
359
+ arathna, Nagendra, & Telles, 1997). Such a study was possible as there are
360
+ certain yoga breathing techniques in which practitioners learn to breathe
361
+ through either one of the nostrils at a time or to alternate between nostrils
362
+ (these are called pranayamas). These maneuvers are done by occluding one
363
+ nostril with the thumb and ring finger of the dominant hand in a charac­
364
+ teristic yoga pose called nasika mudra (Swami Niranjanananda Saraswati,
365
+ 1994). These yoga breathing practices impose uninostril or alternate nos­
366
+ tril yoga breathing on the practitioner, hence they occur quite separate­
367
+ ly from the spontaneously occurring nasal cycle. The 1994 study showed
368
+ that right-, left-, and alternate-nostril yoga breathing practiced over a 10-
369
+ day period all brought about a bilateral increase in the hand-grip strength
370
+ (Raghuraj, et al., 1997).
371
+ The present study was intended to assess the immediate effect of
372
+ right-, left-, and alternate-nostril breathing on bilateral hand-grip strength.
373
+ When each of the breathing techniques was practiced for 20 min., hand-
374
+ grip strength was assessed before and after each of them.
375
+ Method
376
+ Subjects
377
+ Twenty-one male volunteers whose ages ranged from 20 to 42 years
378
+ (M age = 26.0, SD = 5.5 yr.) were selected. Their range of experience of prac­
379
+ ticing yoga breathing techniques was 3 mo. to 7 yr. (M experience = 39.4,
380
+ SD = 57.3 mo.). The volunteers were informed about the study, and their
381
+ signed consent was obtained. They were all right-hand dominant based
382
+ on the Edinburgh Handedness Inventory (Oldfield, 1971).
383
+ Design
384
+ Each subject was assessed in five sessions, which were (i) right-nostril
385
+ yoga breathing, (ii) left-nostril yoga breathing, (iii) alternate-nostril yoga
386
+ breathing, (iv) breath awareness, and (v) control (no-intervention ses­
387
+ sion). The participants were randomly assigned to a sequence of five ses­
388
+ sions using a random number table (Zar, 1999). Hence, each subject was
389
+ assessed in five sessions on five different days. Possibly, a better design
390
+ would have been systematically rotating the conditions so that an equal
391
+ number of subjects practiced the manipulation in every order, such as an
392
+ incomplete Latin Square whereby one-fifth of the participants would have
393
+ had the order 1, 2, 3, 4, 5; one-fifth of the participants the order 5, 1, 2, 3, 4;
394
+ and one-fifth the order 4, 5, 1, 2, 3, and so on. Since this was not done, it is
395
+ hard to say whether there were carry-over effects in people’s practice, es­

398
+ 3
399
+ pecially if the control condition was the last one. This is a methodological
400
+ limitation of the study.
401
+ Assessment
402
+ The hand-grip strength of both hands was assessed using a hand-grip
403
+ dynamometer (Lafayette Instruments, Co., Model No.76618, USA). Partic­
404
+ ipants were tested in six trials, three trials for each hand alternately, with
405
+ an interval of 10 sec. between trials. During assessment, participants were
406
+ asked to keep the arm extended at shoulder level out to the side, horizon­
407
+ tal to the ground as has been described earlier (Madan, Thombre, Bhara­
408
+ thi, Nambinarayan, Thakur, Krishnamurthy, et al., 1992). The maximum
409
+ value, the average value, and the final value out of three readings were
410
+ used for statistical analysis.
411
+ Intervention
412
+ Each subject had three pranayama sessions and two control sessions.
413
+ The sessions were for 20 min. on five separate days at the same time of
414
+ the day. The five sessions are mentioned: (1) right-nostril yoga breathing
415
+ or suryanuloma viloma pranayama practice involves breathing exclusively
416
+ through the right nostril while the left nostril is occluded. (2) Left-nos­
417
+ tril yoga breathing or chandra anuloma viloma pranayama practice involves
418
+ breathing through the left nostril exclusively while the right nostril is oc­
419
+ cluded. (3) Alternate-nostril yoga breathing or nadisuddhi pranayama prac­
420
+ tice involves breathing out from the left nostril, breathing in from the left
421
+ nostril, breathing out from the right nostril, breathing in from the right
422
+ nostril, and breathing out from the left nostril. This is one “round”. Also,
423
+ (4) in the breath-awareness session, participants maintained awareness
424
+ of the breath without manipulation of the nostrils (Nagendra, Mohan, &
425
+ Shriram, 1988). Throughout these practices, participants’ eyes were closed,
426
+ and they sat cross-legged with focus on awareness of the breath. During
427
+ these four practices, participants’ attention was directed to the flow of air
428
+ as it moved through the nostrils. (5) In the control session, participants
429
+ were asked to sit at ease without being aware of the breath. For expe­
430
+ rienced yoga practitioners it could be difficult to remain without breath
431
+ awareness. This also limits the present findings. This session was intend­
432
+ ed to assess whether the hand-grip strength changed when the assessment
433
+ was repeated after 20 min. with no intervention between the first assess­
434
+ ment and the second one 20 min. later. In the three pranayamas involving
435
+ nostril manipulation, the thumb and the ring finger of the dominant hand,
436
+ which was the right hand for these participants, were used to manipulate
437
+ or occlude the nostrils. This is a characteristic yoga gesture (nasika mudra
438
+ in Sanskrit), prescribed during pranayama practice (Swami Niranjananan­
439
+ da Saraswati, 1994).

443
+ Data Analysis
444
+ The data obtained before and after all yoga breathing practices, i.e.,
445
+ right-nostril yoga breathing, left-nostril yoga breathing, alternate-nostril
446
+ yoga breathing, breath awareness, and the control period, were compared.
447
+ Using SPSS, Version 10.0, a repeated-measures analysis of variance was
448
+ carried out with three within-subjects factors, i.e., Sessions (5 levels), As­
449
+ sessments (2 levels, pre- and posttest), and Hands (2 levels; left and right).
450
+ Posttest data were compared with pretest data of the respective session
451
+ using post hoc analysis with a Bonferroni adjustment.
452
+ These analyses were carried out for the average of three values, the
453
+ final value, and the maximum of the three. In addition, an analysis of co­
454
+ variance was carried out using the pre- and posttest values from the no-
455
+ breath awareness control condition as a covariate.
456
+ Results
457
+ The groups’ mean values for hand-grip strength for all the yoga breath­
458
+ ing practices are given in Table 1. An analysis of covariance was done us­
459
+ ing the control session pre- and posttest values as covariates. There was no
460
+ significant difference among any of the sessions for left-hand-grip strength
461
+ (p = .08 for the omnibus analysis of covariance). The same analysis for the
462
+ right hand gave a p value of .09 for the omnibus analysis of covariance.
463
+ The three repeated-measures analyses of variance showed no signifi­
464
+ cant difference among Sessions, Assessments, or Hands, as well as no in­
465
+ teractions among these factors (p > .05, in all cases). This was true for the
466
+ average value, the final value, and the maximum of the three values.
467

468
+ was no attempt to conduct post hoc analyses. Instead, pretest and post­

520
+ test comparisons were made at both one-tailed and two-tailed t tests for
521
+ paired data. The left hand-grip strength following left-nostril breathing
522
+ showed a decrease (p < .05, one-tailed).
523
+ The absence of change appeared related to the small effect size. An a
524
+ priori analysis using the effect size showed that the sample size required to
525
+ produce effects would be extremely large, far exceeding the present sample
526
+ size of 21 persons for α value of .05. This analysis was done with G*Power
527
+ software, Version 3.0.10 (Faul, Erdfelder, Lang, & Buchner, 2007).
528
+ Discussion
529
+ The bilateral hand-grip strength was recorded for 21 male volun­
530
+ teers before and after four yoga breathing practices, and a no-intervention
531
+ session, each practiced on a separate day. Despite different methods of
532
+ analysis, no effect of the breathing practices on hand-grip strength could
533
+ be seen. The sole change was a trend of decrease in the left hand-grip
534
+ strength following left-nostril yoga breathing which is not convincing and
535
+ hence is not discussed further.
536
+ A previous study assessed effects of yoga breathing techniques, i.e.,
537
+ right-, left-, alternate-nostril yoga breathing and one control group on bi­
538
+ lateral hand-grip strength (Raghuraj, et al., 1997). The subjects were 130
539
+ children attending a 10-day residential yoga camp, and the techniques
540
+ were practiced as “27 rounds” four times a day. The assessments were on
541
+ the first day and after 10 days. There was bilateral increase in hand-grip
542
+ strength in all three experimental groups. In this earlier study, the effects
543
+ were studied over a 10-day period, whereas in the present study, assess­
544
+ ments were made immediately before and after 20-min. practice of the in­
545
+ terventions.
546
+ The absence of change in hand-grip strength following the yoga
547
+ breathing practices could be related to certain methodological issues
548
+ apart from the possibility that the yoga breathing practices really did not
549
+ change hand-grip strength. The methodological issues are relevant to
550
+ yoga research and particularly to studies of this kind requiring the par­
551
+ ticipation of volunteers who are experienced in specific yoga techniques.
552
+ The first issue is related to the study’s design. Early studies on medita­
553
+ tion compared the effects of Transcendental MeditationTM with nonmedi­
554
+ tation in age-matched volunteers (Wallace, Benson, & Wilson, 1971).
555
+ However, given the fact that yoga practices are closely related to the
556
+ mental state (Lutz, Slagter, Dunne, & Davidson, 2008) and hence can be
557
+ expected to vary considerably among individuals, an alternative study de­
558
+ sign was devised (Telles & Desiraju, 1993). This design is a self-as-control
559
+ design. In this type of design the same individual is assessed in repeated
560
+ sessions (e.g., meditation and nonmeditation) on separate days to reduce
561
+ interindividual variability. Such a design was used in the present study;

565
+ however the design has a risk of a carry-over effect whereby the effect of
566
+ one practice influences the effects of the practice following it.
567
+ The second methodological issue is the small sample size. It is of­
568
+ ten difficult to get volunteers having adequate experience with the yoga
569
+ technique being studied, who are willing to participate in repeated as­
570
+ sessments. However, when studying the immediate effect of a practice as
571
+ subtle as yoga breathing techniques (pranayamas), it appears necessary to
572
+ have a much larger sample size than in studies where the effects may be
573
+ less subtle (Telles, Naveen, Dash, Deginal, & Manjunath, 2006).
574
+ Hence, the present study highlights the importance of certain issues
575
+ when designing studies of yoga. These are (i) obtaining as large a sam­
576
+ ple size as possible when studying change with a small effect size, as was
577
+ seen here, and (ii) avoiding study of the same individual in too many re­
578
+ peated sessions to prevent a carry-over effect and boredom of the volun­
579
+ teers. To evaluate whether these yoga breathing practices actually influ­
580
+ ence the hand-grip strength, in future, further studies should be planned
581
+ with a large number of volunteers and each would be assessed at the most
582
+ in two sessions.

+ Summary.—Bilateral hand-grip strength was studied in 21 male volunteers (M age=25.6 yr.,
670
+ SD=5.2). All were assessed before and after five practice sessions of 20 min. duration: right-nostril
671
+ yoga breathing, left-nostril yoga breathing, alternate-nostril yoga breathing, breath awareness, and a
672
+ no-intervention session. Data were analyzed with analyses of variance and an analysis of variance
673
+ using the no-breath awareness control condition as a covariate. There were no significant changes.
674
+ The left-hand-grip strength reduced after left-nostril yoga breathing. However, findings were not
675
+ considered significant, so methodological issues in yoga research which could contribute to null
676
+ findings and even mask actual changes were discussed.

695
+ The basic-rest-activity cycle (BRAC) was initially described based on observations made
696
+ for infants and was later shown also to hold for adults (Kleitman, 1963). Various physiological
697
+ processes are entrained to this rhythm. One of the lesser known is the nasal cycle.
698
+ The nasal cycle is an ultradian rhythm during which both nostrils are alternately patent.
699
+ Originally, the periodicity was reported to range between 2 and 8 hours. (Keuning, 1868).
700
+ However, time analyses detected periods for the nasal cycle and coregulated systems. These periods
701
+ were at 280–300, 215–275, 165–210, 145–160, 105–140, 70–100, and 40–65 minutes, with the
702
+ greatest spectral power in longer periods during waking (Shannahoff-Khalsa, Kennedy, Yates, &
703
+ Ziegler, 1996, 1997). While the nasal cycle is coupled to other rhythms such as alternating cerebral
704
+ hemispheric dominance and autonomic activity, it has also been suggested that right nostril
705
+ dominance may corelate with the activity phase of the basic-rest-activity cycle (Werntz, Bickford,
706
+ Bloom, & Shannahoff-Khalsa, 1983; Shannahoff-Khalsa, 2008).
707
+ A very early description by Wada in 1922, presented a relation between basic rhythms (i.e.,
708
+ hunt-eat-rest) and hand-grip strength (Shannahoff-Khalsa, 1991; Shannahoff-Khalsa, 2008). Hand-
709
+ grip strength is used to assess general strength, and hence, underlies work capacity, extent of injury
710
+ and disease, and the possibility of rehabilitation (Petersen, Petrick, Connor, & Conklin, 1989).
711
+ Motor activity during wakefulness showed greater hand-grip strength during periods of hunger
712
+ contractions than for quiescent or postmeal periods. This rhythm, i.e., hunt-eat, then rest, may be
713
+ considered another way of viewing the basic-rest-activity cycle. Given this connection between
714
+ basic-rest-activity cycle and hand-grip strength and the speculation that right nostril breathing
715
+ corresponds to the activity phase of the basic-rest-activity cycle, the effect of uninostril breathing
716
+ on hand-grip strength has been studied in yoga practitioners (Raghuraj, Nagarathna, Nagendra, &
717
+ Telles, 1997). Such a study was possible as there are certain yoga breathing techniques in which
718
+ practitioners learn to breathe through either one of the nostrils at a time or to alternate between
719
+
720
+ 4
721
+ nostrils (these are called pranayamas). These maneuvers are done by occluding one nostril with the
722
+ thumb and ring finger of the dominant hand in a characteristic yoga pose called nasika mudra
723
+ (Swami Niranjanananda Saraswati, 1994). These yoga breathing practices impose uninostril or
724
+ alternate nostril yoga breathing on the practitioner, hence they occur quite separately from the
725
+ spontaneously occurring nasal cycle. The 1994 study showed that right-, left-, and alternate-nostril
726
+ yoga breathing practiced over a 10-day period all brought about a bilateral increase in the hand-grip
727
+ strength (Raghuraj, et al., 1997).
728
+ The present study was intended to assess the immediate effect of right-, left-, and alternate-
729
+ nostril breathing on bilateral hand-grip strength. When each of the breathing techniques were
730
+ practiced for 20 min., hand-grip strength was assessed before and after each of them.
731
+ Method
732
+ Subjects
733
+ Twenty-one male volunteers whose ages ranged from 20 to 42 years (M age=26.0, SD=5.5
734
+ yr.) were selected. Their range of experience of practicing yoga breathing techniques was 3 mo. to 7
735
+ yr. (M experience=39.4, SD=57.3 mo.). The volunteers were informed about the study, and their
736
+ signed consent was obtained. They were all right-hand dominant based on the Edinburgh
737
+ Handedness Inventory (Oldfield, 1971).
738
+ Design
739
+ Each subject was assessed in five sessions, which were (i) right-nostril yoga breathing, (ii)
740
+ left-nostril yoga breathing, (iii) alternate-yoga nostril breathing, (iv) breath awareness, and (v)
741
+ control (no-intervention session). The participants were randomly assigned to a sequence of five
742
+ sessions using a random number table (Zar, 1999). Hence, each subject was assessed in five
743
+ sessions on five different days. Possibly, a better design would have been systematically rotating
744
+ the conditions so that an equal number of subjects practiced the manipulation in every order, such
745
+
746
+ 5
747
+ as an incomplete Latin Square whereby one-fifth of the participants would have had the order 1, 2,
748
+ 3, 4, 5; one-fifth of the participants the order 5, 1, 2, 3, 4; and one-fifth the order 4, 5, 1, 2, 3, and so
749
+ on. Since this was not done, it is hard to say whether there were carry-over effects in people’s
750
+ practice, especially if the control condition was the last one. This is a methodological limitation of
751
+ the study.
752
+ Assessment
753
+ The hand-grip strength of both hands was assessed using a hand-grip dynamometer
754
+ (Lafayette Instruments, Co., Model No.76618, USA). Participants were tested in six trials, three
755
+ trials for each hand alternately, with an interval of 10 sec. between trials. During assessment,
756
+ participants were asked to keep the arm extended at shoulder level out to the side, horizontal to the
757
+ ground as has been described earlier (Madan, Thombre, Bharathi, Nambinarayan, Thakur,
758
+ Krishnamurthy, et al., 1992). The maximum value, the average value, and the final value out of
759
+ three readings were used for statistical analysis.
760
+ Intervention
761
+ Each subject had three pranayama sessions and two control sessions. The sessions were for
762
+ 20 min. on five separate days at the same time of the day. The five sessions are mentioned: (1)
763
+ right-nostril yoga breathing or suryanuloma viloma pranayama practice involves breathing
764
+ exclusively through the right nostril while the left nostril is occluded; (2) left-nostril yoga breathing
765
+ or chandra anuloma viloma pranayama practice involves breathing through the left nostril
766
+ exclusively while the right nostril is occluded; (3) alternate-nostril yoga breathing or nadisuddhi
767
+ pranayama practice involves breathing out from the left nostril, breathing in from the left nostril,
768
+ breathing out from the right nostril, breathing in from the right nostril, and breathing out from the
769
+ left nostril. This is one “round”. Also, (4) in the breath-awareness session, participants maintained
770
+ awareness of the breath without manipulation of the nostrils (Nagendra, Mohan, & Shriram, 1988).
771
+
772
+ 6
773
+ Throughout these practices, participants’ eyes were closed, and they sat cross-legged with focus on
774
+ awareness of the breath. During these four practices, participants’ attention was directed to the flow
775
+ of air as it moved through the nostrils. (5) In the control session, participants were asked to sit at
776
+ ease without being aware of the breath. For experienced yoga practitioners it could be difficult to
777
+ remain without breath awareness. This also limits the present findings. This session was intended to
778
+ assess whether the hand-grip strength changed when the assessment was repeated after 20 min. with
779
+ no intervention between the first assessment and the second one 20 min. later. In the three
780
+ pranayamas involving nostril manipulation, the thumb and the ring finger of the dominant hand,
781
+ which was the right hand for these participants, was used to manipulate or occlude the nostrils. This
782
+ is a characteristic yoga gesture (nasika mudra in Sanskrit), prescribed during pranayama practice
783
+ (Swami Niranjanananda Saraswati, 1994).
784
+ Data Analysis
785
+
786
+ The data obtained before and after all yoga breathing practices, i.e., right-nostril yoga
787
+ breathing, left-nostril yoga breathing, alternate-nostril yoga breathing, breath awareness, and the
788
+ control period were compared. Using SPSS, Version 10.0, a repeated-measures analysis of variance
789
+ was carried out with three within-subjects factors, i.e., Sessions (5 levels), Assessments (2 levels,
790
+ pre- and posttest), and Hands (2 levels; left and right). Posttest data were compared with pretest
791
+ data of the respective session using post hoc analysis with a Bonferroni adjustment.
792
+ These analyses were carried out for the average of three values, the final value and the
793
+ maximum of the three. In addition, an analysis of covariance was carried out using the pre- and
794
+ posttest values from the no-breath awareness control condition as a covariate.
795
+ Results
796
+ The groups’ mean values for hand-grip strength for all the yoga breathing practices are
797
+ given in Table 1. An analysis of covariance was done using the control session pre- and posttest
798
+
799
+ 7
800
+ values as covariates. There was no significant difference among any of the sessions for left-hand-
801
+ grip strength (p=.08 for the omnibus analysis of covariance). The same analysis for the right hand
802
+ gave a p value of .09 for the omnibus analysis of covariance.
803
+ Insert TABLE 1 about here
804
+ The three repeated-measures analysis of variance showed no significant difference among
805
+ Sessions, Assessments, or Hands, as well as no interactions among these factors (p>.05, in all
806
+ cases). This was true for the average value, the final value and the maximum of the three values.
807
+ Since none of the above analyses showed statistical significance, there was no attempt to
808
+ conduct post hoc analyses. Instead, pretest and posttest comparisons were made at both one-tailed
809
+ and two-tailed t tests for paired data. The left hand-grip strength following left nostril breathing
810
+ showed a decrease (p<.05, one-tailed).
811
+ The absence of change appeared related to the small effect size. An a priori analysis using
812
+ the effect size showed that the sample size required to produce effects would be extremely large, far
813
+ exceeding the present sample size of 21 persons for α value of .05. This analysis was done with
814
+ G*Power software, Version 3.0.10 (Faul, Erdfelder, Lang, & Buchner, 2007).
815
+ Discussion
816
+ The bilateral hand-grip strength was recorded for 21 male volunteers before and after four
817
+ yoga breathing practices, and a no-intervention session each practiced on a separate day. Despite
818
+ different methods of analysis, no effect of the breathing practices on hand-grip strength could be
819
+ seen. The sole change was a trend of decrease in the left hand-grip strength following left-nostril
820
+ yoga breathing which is not convincing and hence is not discussed further.
821
+ A previous study assessed effects of yoga breathing techniques i.e., right-, left-, alternate-
822
+ nostril yoga breathing and one control group on bilateral hand-grip strength (Raghuraj, et al., 1997).
823
+ The subjects were 130 children attending a 10-day residential yoga camp, and the techniques were
824
+
825
+ 8
826
+ practiced as “27 rounds” four times a day. The assessments were on the first day and after 10 days.
827
+ There was bilateral increase in hand-grip strength in all three experimental groups. In this earlier
828
+ study, the effects were studied over a 10-day period, whereas in the present study, assessments were
829
+ made immediately before and after 20-min. practice of the interventions.
830
+ The absence of change in hand-grip strength following the yoga breathing practices could be
831
+ related to certain methodological issues apart from the possibility that the yoga breathing practices
832
+ really did not change hand-grip strength. The methodological issues are relevant to yoga research
833
+ and particularly to studies of this kind requiring the participation of volunteers who are experienced
834
+ in specific yoga techniques. The first issue is related to the study’s design. Early studies on
835
+ meditation compared the effects of Transcendental MeditationTM
836
+ The second methodological issue is the small sample size. It is often difficult to get
837
+ volunteers having adequate experience with the yoga technique being studied, who are willing to
838
+ participate in repeated assessments. However, when studying the immediate effect of a practice as
839
+ subtle as yoga breathing techniques (pranayamas), it appears necessary to have a much larger
840
+ sample size than in studies where the effects may be less subtle (Telles, Naveen, Dash, Deginal, &
841
+ Manjunath, 2006).
842
+ with nonmeditation in age-
843
+ matched volunteers (Wallace, Benson, & Wilson, 1971).
844
+ However, given the fact that yoga practices are closely related to the mental state (Lutz,
845
+ Salgter, Dunne, & Davidson, 2008) and hence can be expected to vary considerably among
846
+ individuals, an alternative study design was devised (Telles & Desiraju, 1993). This design is a self-
847
+ as-control design. In this type of design the same individual is assessed in repeated sessions, (e.g.,
848
+ meditation and nonmeditation) on separate days to reduce interindividual variability. Such a design
849
+ was used in the present study; however the design has a risk of a carry-over effect whereby the
850
+ effect of one practice influences the effects of the practice following it.
851
+
852
+ 9
853
+ Hence, the present study highlights the importance of certain issues when designing studies
854
+ on yoga. These are (i) obtaining as large a sample size as possible when studying change with a
855
+ small effect size, as was seen here, and (ii) avoiding study of the same individual in too many
856
+ repeated sessions to prevent a carry-over effect and boredom of the volunteers. To evaluate whether
857
+ these yoga breathing practices actually influence the hand-grip strength, in future, further studies
858
+ should be planned with a large number of volunteers and each would be assessed at the most in two
859
+ sessions.

+ Abstract
4
+ Original Article
5
+ Introduction
6
+ Neurocognition is a sub‑discipline of neuroscience.
7
+ Neurocognitive abilities include learning, memory, perception,
8
+ attention, alertness, and problem‑solving. These abilities are
9
+ the brain‑mind skills needed to initiate any task from the
10
+ simplest to the most complex. The process of normal aging is
11
+ associated with substantial declines in cognitive abilities, which
12
+ include speed and accuracy of perception, decision‑making,
13
+ task‑switching, working memory, and multitasking. The
14
+ basic neurocognitive functions mainly attention‑alertness
15
+ and memory are markedly affected by age.[1,2] Last three
16
+ decades investigations on mind body interventions signify
17
+ on neurocognitive functions suggested promising effect
18
+ in slowing or reversing the cognitive decline associated
19
+ with aging process.[3,4] Further, research investigations in
20
+ the field of exercise science clearly indicated that regular
21
+ moderate exercise habit reduces the risk factor associated
22
+ with neurocognitive decline in healthy individuals.[1‑4] Yoga
23
+ is considered a mind‑body practice of Indian origin, which
24
+ confirms its potential benefits on the functional ability of
25
+ neurocognitive aspects. There are studies on the effect of
26
+ yoga (single or multiple interventions) and the improvement
27
+ of neuropsychological or psychophysiological functions.[5,6]
28
+ However, there is no study found on the effect of combined
29
+ graded yogic training on neurocognitive abilities among
30
+ middle‑aged population, although it is a vulnerable phase of life
31
+ from where every person may start the normal aging process.
32
+ Therefore, the present study was conducted to see the effect
33
+ of Six and twelve weeks of yogic training on neurocognitive
34
+ abilities among the middle‑aged group.
35
+ Background: Neurocognitive abilities are the brain‑mind skills needed to initiate any task from the simplest to the most complex, decreases with
36
+ advancing age. Attention, alertness, and memory are the basic neurocognitive functions most affected by age. There are potential benefits of yoga
37
+ on neurocognitive functions because this ancient Indian technique positively nurtures the mind‑body systems. Aim of the Study: The present
38
+ study was aimed to evaluate the effect of 12 weeks of yogic training on neurocognitive abilities in a middle‑aged group. Methods: A total of 86
39
+ volunteers (46 male and 40 females, age group of 35–55 years), with no prior experience of yoga were participated in this study. Five male
40
+ and 4 female participants were excluded from the study. All participants divided into yoga training group (male = 21 and female = 18) and
41
+ control group (male = 20 and female = 18). The yoga training group underwent yoga practices, including kriya, surya namaskar, asana,
42
+ pranayama, and dhyana daily in the morning, for 6 days/week, for 12 weeks. Standing height, body weight, body mass index, visual reaction
43
+ time (RT), auditory RT (attention and alertness), and short‑term memory were assessed day 1 (pre), 6th week (mid), and 12th weeks (post) of
44
+ intervention. Results: Repeated‑measures analysis of variance showed that a statistically significant increased (P < 0.05) in attention‑alertness
45
+ and short‑term memory after 12 weeks of yogic practices. Conclusion: Integrated approach of yogic intervention may have promising effect
46
+ on neurocognitive abilities that concomitantly promote successful aging.

+ Methods
78
+ Study location
79
+ The present study was carried out in the city of Bolpur, West
80
+ Bengal, India.
81
+ Population
82
+ The target population was middle‑aged men and women.
83
+ Subjects
84
+ To meet the specific objective of the study and to find out
85
+ the motivated participants, a workshop on “Healthy aging
86
+ through Yoga” was organized in the locality of Bolpur city,
87
+ District–Birbhum, State–West Bengal, India. There was total
88
+ 86 adult men (n = 46) and women (n = 40) aged between 35
89
+ and 55 years willingly enrolled their names to join this yoga
90
+ and healthy aging workshop. The sample size calculation was
91
+ not done before the study. However, the post hoc analysis of
92
+ auditory reaction time (RT) of male in the yoga group showed
93
+ that with the sample size 86, the calculated effect size is 0.96
94
+ and power is 0.99 of the study.[7] All participants were from
95
+ almost similar in socioeconomical background, recreationally
96
+ active but they have no prior experience any form of yoga
97
+ before the commencement of specific yoga training. Based on
98
+ a routine clinical examination, nine participants (5 male and
99
+ 4 female) were excluded from the study due to major injury
100
+ and illness. The participants who were (n = 77; male 41 and
101
+ female 36) found in normal health and none of them taking any
102
+ medication were considered for the study. All the participants
103
+ were living in Bolpur city and following a similar lifestyle
104
+ pattern. All of them were nonvegetarian.
105
+ Study designed
106
+ Quasiexperimental research design and convenient sampling
107
+ method were considered to enroll subjects. All participants were
108
+ divided into two groups in respect to their serial of registration
109
+ for the workshop. First 39 participants were served (male 21;
110
+ age 39.81 ± 9.13 years; female 18, age 41.75 ± 8.70 years)
111
+ as the yoga training group and remaining others (n = 38)
112
+ were served as a nonyoga practicing group (male 20, age
113
+ 40.17 ± 8.37 years; female 18, age 42.33 ± 8.23 years). The
114
+ University Research Review Board approved the study and
115
+ signed informed consent form was obtained from each subject.
116
+ All participants were tested‑three times, i.e., day 1 (pre),
117
+ after 6th week (mid), and after 12th week (post) assessment,
118
+ under similar laboratory condition. Participants were free to
119
+ withdraw themselves from the yoga training or assessments at
120
+ any point of time during the study. The final number of each
121
+ group completed the study is shown in the flow diagram of
122
+ quasi‑experimental trials [Figure 1].
123
+ Assessments
124
+ Demographic information, including age, gender,
125
+ socioeconomic status, education, and anthropometric
126
+ measurements, was taken on the day of enrolment. Further,
127
+ participants were assessed for neurocognitive abilities by
128
+ using visual RT (VRT), auditory RT (ART), and short‑term
129
+ memory. RT is an interval time between stimulus (S) and
130
+ response (R) in a given situation. RT was used as an index of
131
+ cognitive performance change, was considered as it correlates
132
+ with many central nervous system conditions. Digital reaction
133
+ timer (Lafayette Instrument Multi‑Operational Apparatus for
134
+ RT, Model No. 35600) was used for the collection of data.
135
+ Two modes were used to measure the RT, i.e., VRT using
136
+ “Light” stimulus; ART using “Audio” stimulus. RT was
137
+ recorded in term of milliseconds unit. Each subject was given
138
+ 10 trials, and then, average of these trials was considered as
139
+ the RT of that subject. It was regarded as lesser the time is
140
+ better the cognitive ability (Manual, Lafayette Instrument,
141
+ 3700 Sagamore Parkway North, P.O. Box 5729, Lafayette, In
142
+ 47903 USA). The short‑term memory is holding small amount
143
+ of information for the short period of time. The short‑term
144
+ memory was measured through “serial learning” test by using
145
+ “Digital Memory Scope” instrument (Medicaid System, 389,
146
+ Ind. Area, Phase‑II, Chandigarh ‑ 160 002, India). Serial
147
+ Learning was recorded in terms of the right attempt made by
148
+ the subject out of 10 numbers accordingly.

193
+ reach 90 min at the end of 6 weeks. Finally, 1 h 45 min practice
194
+ times were fixed in the beginning of 8th week and continue
195
+ till 12–weeks. The detailed yogic practices were reported
196
+ elsewhere.[8,9] Furthermore, a general record was maintained
197
+ of the subjects’ activities, diet, and lifestyle during the study
198

200
+ The subjects of the waitlist control group following their usual
201
+ routine activities. They are instructed to report in the laboratory
202
+ once in a week. Researcher kept a detail history of their daily
203
+ lifestyles during these 12 weeks.
204
+ Statistical analysis
205
+ Data obtained through different tests and measurements were
206
+ processed for data analysis. Mean and standard deviation
207
+ as descriptive statistic, repeated measures analysis of
208

209
+ for the data analysis. The RM ANOVA was utilized for two
210
+ factors, i.e., factor 1 within groups‑time points (pre, mid, and
211
+ post) measurements and factor 2 between Groups‑differences
212
+ between the groups (yoga practicing group and nonyoga
213
+ practicing group). Post hoc test was followed with within
214
+ and between groups’ factors. Significant level was set at 0.05
215
+ levels (P < 0.05).
216
+ Results
217
+ Baseline status
218
+ An insignificant baseline difference was found
219
+ between yoga practicing group and nonyoga practicing
220
+ group for both male and female participants separately
221
+ [Table 1].
222
+ Effect of yoga on physical characteristics
223
+ In yoga practicing group for both male and female, body weight
224
+ and body mass index were fall significantly (P < 0.001) after
225
+ 12 weeks of yogic practices compare to baseline; however,
226
+ in the nonyoga practicing group, no such changes were
227
+ found (P > 0.05).
228
+ Effect of yoga on neurocognitive variables
229
+ Attention and alertness
230
+ Following 6‑week and 12‑week of combined yoga practices
231
+ showed a significant improvement in auditory and visual
232
+ reaction time compared to baseline data, in male and female
233
+ yoga‑practicing group [Table 2], whereas no such changes were
234
+ found in the non‑yoga practicing group [Figure 2]. Similarly,
235
+ the short‑term memory was measured through serial learning
236
+ test showed a significant improvement after 12‑week yogic
237
+ practices [Table 2 and Figure 3].
238
+ Discussion
239
+ It is evident that regular exercise or physical activity of
240
+ mild to moderate intensity, i.e., walking, freehand exercises,
241
+ stretching exercises, moderate strength exercises, obviously
242
+ reduces the risk of neurocognitive decline compared to
243
+ sedentary lifestyle.[2,10,11] However, this probably the first
244
+ quasi‑experimental study in which, 12 weeks combined yoga
245
+ practice regimen was applied to observe the neurocognitive
246
+ response in a middle‑aged group with normal health status.
247
+ The results of the present study showed a significant decrease
248
+ in ART and VRT following 6‑week and 12‑week practice
249
+ of yoga. This outcome clearly indicates improvement of
250
+ one’s attention and alertness. The outcomes are in line with
251
+ previous reports that yogasana can produce a significant
252
+ reduction in the RT of ART and VRT.[12] It was reported that
253
+ voluntary control on the time period of inspiratory breathing
254
+ positively correlated with the changes in RT.[13] Another study
255
+ reported that the RT was improved after the practice of Mukh
256
+ Bhastrika.[14] Further, 12 weeks of yoga training (asana and
257
+ pranayama) decrease RT[15] and also reported shortening of RT
258
+ after pranayama practice.[16] In a study, Borker and Pednekar[17]
259
+ reported that ART and VRT reduced significantly after 4 weeks
260
+ of pranayamic breathing exercises. In a recent study, Telles
261
+ et al.[15] reported that RT was decreased significantly after
262
+ the session of breath awareness and quite sitting, whereas no
263
+ change was observed immediately after 18 min of Bhastrika
264
+ pranayama. RT has been considered an indirect index for the
265
+ measurement of the processing ability of the central nervous
266
+ system and also a method used to determine sensory‑motor

300
+ association and performance.[18] It involves a central neural
301
+ mechanism and also an index of cortical arousal.[18] A decrease
302
+ in RT indicates improved sensory‑motor performance and
303
+ enhanced processing ability of the central nervous system.
304
+ Finally, a decrease in ART and VRT clearly expresses a
305
+ positive improvement in the sensory‑motor processing ability
306
+ that may broadly interpret as the development of central
307
+ nervous system functions. Therefore, from the findings of the
308
+ present study, it may be concluded that yogic intervention
309
+ for a period of 12 weeks positively improved this processing
310
+ ability by (i) the higher rate of information processing,
311
+ (ii) improving the power of concentration and the ability to
312
+ ignore extraneous stimuli factors, (iii) higher arousal and the
313
+ ability of faster information processing could be understood
314
+ as the alterations in afferent inputs and efferent outputs, which
315
+ may further control the activity of ascending and descending
316
+ activity of the reticular system in thalamo‑cortical levels,
317
+ and (iv) a decrease in sympathetic activity and increased
318
+ parasympathetic activity may enhance the concentration
319
+ ability and bring deep psychosomatic relaxation and decrease
320
+ in oxygen consumption. All these above possible mechanisms
321
+ may be attributed to the decrease of visual and ART. From the
322
+ above discussion, it may be concluded that a combined yoga
323
+ regimen in the middle‑aged group may improve attention and
324
+ alertness as reflected through the RT results.
325
+ In the present study, researcher evaluates the effect of yogic
326
+ training on short‑term memory in a middle‑aged group. It was
327
+ found that short‑term memory was improved significantly in
328
+ the form of the serial learning score after 6th and 12th weeks
329
+ of yoga training. From the evidence, it could be observed that
330
+ aging may disrupt old memory and the processing of new
331
+ memory. Yoga is a type of mind‑body intervention, regular
332
+ practice of which helps to improve individual memory, which
333
+ includes perception, concentration, and attention span.[19]
334
+ Naveen et al. studied the impact of uninostril breathing on
335
+ verbal and spatial memory tests in school children. On the
336
+ basis of different breathing practices, all the students were
337
+ randomly categorized into four groups, i.e., (a) right nostril
338
+ breathing, (b) left nostril breathing, (c) alternate nostril
339
+ breathing, or (d) breath awareness without manipulation of
340
+ nostrils. They found a significant increase in spatial memory
341
+ scores in all four experimental groups after 10 days of
342
+ yoga breathing practice, but no such change was observed
343
+ in the control group.[20] Sahaj yoga practice can lead to an
344
+ improvement in verbal working memory[21] and breathing
345
+ through the left nostril able to increase the spatial cognitive
346
+ task.[22] In a study, Subramanya and Telles reported that
347
+ memory scores were improved immediately after the practice
348
+ of cyclic meditation.[23] The yogic education system improves
349
+ visual and verbal memory scores in school boys compared to
350
+ the modern education system.[24]
351
+ In the present study, short‑term memory in the form of
352
+ serial learning scores significantly improved after yogic
353
+ practices in the middle‑aged group. It can be interpreted
354
+ as (i) Anxiety inhibit memory development, whereas yoga
355
+ practice reduced anxiety may improve memory scores;[25]
356
+ (ii) Right hemispheric (nonverbal, spatial memory) and
357
+ left hemispheric (verbal memory) improvement after yogic
358
+ training may have a positive effect on memory development;[24]
359
+ (iii) Yogic practices decrease psychophysiological scores of
360
+ arousals, and sympathetic activity may alter hypothalamic
361
+ functions, which is considered the highest center for autonomic
362
+ regulations;[22‑24]  (iv) Regular Yoga practice positively
363
+ improves the concentration, attention span, and visuomotor
364
+ speed, which may influence memory by large; and (v) some
365
+ practices of yogic technique modulate the function of

+ Abstract
26
+
27
+ Introduction: Traumatic Spinal Cord Injury (TSCI) is an
28
+ injury to the spinal cord that results in temporary or
29
+ permanent motor, sensory, and cognitive deficits.
30
+ The current conventional approach of TSCI management
31
+ includes surgery, pharmacology, and physical therapy,
32
+ which have some limitations and are associated with side
33
+ effects. Yoga is a form of mind-body medicine found to be
34
+ effective in several neurological disorders as an-add on to
35
+ other therapies.
36
+ Aim: The present study intended to see the effect of
37
+ Integrated Yoga (IY) intervention as an-add on to the
38
+ physiotherapy on walking index, ESR, pain and spasticity
39
+ among subjects with TSCI.
40
+ Methods: The study was conducted in a Rehabilitation
41
+ Centre at Swami Vivekananda National Institute of
42
+ Rehabilitation, Training and research (SVNIRTAR),
43
+ Odisha. A total of 125 paraplegics within age range 18-60
44
+ years were randomly assigned to either integrated Yoga
45
+ therapy + physiotherapy group (IY + PT) group (n = 62,
46
+ age = 33.97 ± 10.00) or Physiotherapy (PT) group (n = 63,
47
+ age = 32.84 ± 9.47). The participants in PT + IY group
48
+ received one month of integrated yoga intervention
49
+ consisting of yogic postures, yogic breathing techniques &
50
+ chanting, and yogic relaxation practices along with physical
51
+ therapy. Yoga session lasted for 75 mins per day and
52
+ 6 days per week. PT group participants received only
53
+ physiotherapy intervention for one month. All the
54
+ participants were assessed for Erythrocyte Sedimentation
55
+ Rate (ESR), Walking Index for Spinal Cord Injury II
56
+ (WISCI II), Multidimensional Pain Inventory (MPI), and
57
+ Modified-Modified Ashworth Scale (MMAS) at the
58
+ baseline and after one month.
59
+ Results: We found statically significant changes in 4
60
+ variables for IY + PT group 1) Erythrocyte Sedimentation
61
+ Rate (P < 0.001), 2) WISCI II (P < 0.001) MPI-S1
62
+ (P < 0.001), MPI-S2 (P = 0.003), & MPI-S3 (P = 0.003),
63
+ and 4) MMAS (P < 0.001) after one month of intervention
64
+ compared to baseline.

67
+ Compared to PT group, IY + PT group showed
68
+ significantly better improvement in WISCI II (P < 0.001),
69
+ MPI-S3 (P = 0.003), and MMAS (P < 0.001).
70
+ Conclusion: The resent study suggests the usefulness of an
71
+ IY intervention add on to physiotherapy in the management
72
+ of patients with paraplegia.

75
+ Introduction
76
+
77
+ Traumatic Spinal cord injury (TSCI) is a
78
+ medically complex and life-disrupting condition. It is
79
+ an insult to the spinal cord which leads to temporary
80
+ or permanent, sensory, motor and autonomic deficits
81
+ resulting in severe disability (Alexander, Biering-
82
+ Sorensen, Bodner, et al., 2009). Paraplegia is most
83
+ commonly observed condition after TSCI. Paraplegia
84
+ affects the activities of daily living and puts
85
+ socioeconomic burden on family of an individual
86
+ (Wyndaele & Wyndaele, 2006). Spasticity is the most
87
+ common complication which affects gait and
88
+ activities of daily living to a higher degree. It is also
89
+ involved in pain aggravation, deformities and
90
+ contractures (Burchiel, Kim, et al., 2001). Evidences
91
+ from
92
+ several
93
+ studies
94
+ suggest
95
+ that
96
+ paraplegia
97
+ characterized by increased systematic inflammation
98
+ shown by increased ESR (Hausmann, 2003).
99
+ Systematic inflammation in individual with paraplegia
100
+ is associated with increased respiratory and bladder
101
+ infection, further it affects the prognosis of TSCI
102
+ (Diana, Cardenas, Thomas, Hooton, 1995; Gris,
103
+ Hamilton, Weaver, 2008).
104
+ Available treatment for paraplegia in convention
105
+ medicine is surgery, pharmacological intervention
106
+ and physical therapies. Despite, large portion of
107
+ paraplegics report persistent functional disability,
108
+ spasticity and pain. Further, conventional therapies
109
+ have limited efficacy in improving systematic
110
+ inflammation (Bethea, John; Dietrich, Dalton, 2002).
111
+ In order to enhance the present management of
112
+ paraplegia and to get better treatment outcome
113
+ addition of other supportive therapies has become
114
+ mandatory.
115
+ Yoga is a form of mind body interventions. Yoga
116
+ is a lifestyle meant for physical, mental, social and
117
+ spiritual growth of an individual. In present days
118
+ Yoga is perceived as practice of asanas, pranayama,
119
+ and meditation and various kinds of yogic relaxation
120
+ methods (Manas, Kashinath, Nagaratna, Nagendra,
121
+ 2017).
122
+ Several evidences from scientific studies suggest
123
+ the variety of health benefiting effects of yoga. Yoga
124
+ has been found useful in many chronic health
125
+ conditions including various neurological disorders
126
+ such as multiple sclerosis, stroke, Parkinson’s
127
+ disease etc. Studies on Yoga shows to improve
128
+ gait, spasticity, pain, inflammation and QoL among
129
+ neurologically impaired patients (Mishra, Singh,
130
+ Bunch, Zhang, 2012).
131
+ For individuals with SCI, the injury permanently
132
+ transforms their lives. Indeed, SCI can result in
133
+ diverse motor, sensory and autonomic problems
134
+ (Hou, Rabchevsky, 2014). Mobility impairment (e.g.,
135
+ paraplegia and tetraplegia), bowel and bladder
136
+ incontinence, loss of sensation and sexual dysfunction
137
+ are common following SCI (Guilcher, Craven,
138
+ Lemieux-Charles, et al, 2013). As a result, individuals
139
+ with SCI have complex health needs as their
140
+ condition includes chronic multi-morbidity, mainly
141
+ associated with the development of several secondary
142
+ health conditions (e.g., pain and pressure ulcers)
143
+ (Guilcher, Craven, Lemieux, Charles, et al., 2013). In
144
+ addition, compared with community estimates, higher
145
+ rates of psychological disorders can be present in
146
+ 17%–25% of individuals with SCI (Khazaeipour,
147
+ Taheri-Otaghsara,
148
+ Naghdi,
149
+ 2015).
150
+ Particularly,
151
+ between 18% and 37% of individual with SCI
152
+ experience depression (Williams, Murray, 2015).
153
+ From a clinical perspective, understanding the
154
+ needs of individuals with SCI, knowing the person
155
+ and working with the family can be beneficial to
156
+ guide their healthcare and improve outcomes (Stiens,
157
+ Fawber, Yuhas, 2013). As unmet needs have a direct
158
+ relationship with diminished quality of life (Sweet,
159
+ Noreau, Leblond, et al., 2014), it is mandatory to
160
+ understand them and to find ways to meet them. In
161
+ consequence, obtaining a comprehensive picture of
162
+ needs by integrating the different perspectives of
163
+ professionals, family caregivers and individuals with
164
+ SCI is paramount. The challenge is in understanding
165
+ the evolution of these needs as they change over time.
166
+ The literature on SCI needs indicates that in the first-
167
+ year post discharge, the fulfilment of critical needs
168
+ (e.g., housing and transportation) is below 60%
169
+ (Beauregard, Guindon, Noreau, et al., 2012),while the
170
+ long-term care needed is higher than the care received
171
+ Effect of Integrated Yoga as an Add-On to Physiotherapy on Walking Index, ESR, Pain …
172
+ 59
173
+ for information and psychosocial care needs (van
174
+ Loo, Post, Bloemen, et al, 2010).Rehabilitation plays
175
+ a central role in maximizing function and facilitating
176
+ community reintegration following SCI (Anthony,
177
+ Ralph, Sukhvinder, et al., 2017).
178
+ Strategies that seek out the complementary
179
+ effects of combination treatments and that efficiently
180
+ integrate relevant technical advances in biomechanics
181
+ represent an untapped potential and are likely to have
182
+ an immediate impact. There are no published
183
+ randomized control trials till date available to explore
184
+ the efficacy of combination of complementary
185
+ alternative therapies with conventional main stream
186
+ rehabilitation treatments, in the management of SCI.
187
+ Hence, in present study we assessed the impact of
188
+ one month of yoga intervention as an add-on to
189
+ physiotherapy on ESR, walking Index, pain and
190
+ spasticity among participants with paraplegia.

+ normal.
286
+
287
+ ASIA A implies a complete injury, ASIA B – D
288

289
+
290
+
291
+ Ethical Considerations
292
+
293
+ The study protocol was passed by S-VYASA’s
294
+ Institutional Ethics Committee. All procedures were
295
+ performed according to the Declaration of Helsinki
296
+ research ethics. Signed informed consent of all
297
+ subjects was obtained after explaining the nature
298
+ of study in detail and the voluntary nature of
299
+ participation. Confidentiality was assured as part of
300
+ the research process.
301
+ Design of the Study
302
+
303
+ Two group pre–post randomized wait-list control
304
+ (WLC) design is adopted.
305
+
306
+
307
+ Randomisation
308
+
309
+ To avoid selection biases Sequentially Numbered
310
+ Opaque Sealed Envelops (SNOSE) is adopted. After
311
+ screening, the patients are asked to select an opaque
312
+ envelop from the bunch which is randomly arranged
313
+ and the number it contains is not visible outside. The
314
+ envelopes are sequentially numbered but the number
315
+ it contains is not visible outside. The patients are
316
+ then allocated to the experimental or WLC group
317
+ according to the number they receive. Each number is
318
+ separately assigned to either Experimental or WLC
319
+ group randomly.

327
+ Walking Index for SCIII (WISCIII)
328
+ Walking Index for Spinal Cord Injury (WISCI II)
329
+ assesses the amount of physical assistance needed, as
330
+ well as devices required, for walking following
331
+ paralysis that results from Spinal Cord Injury
332
+ (SCI). Designed to be a more precise measure of
333
+ improvement in walking ability specific to SCI. It
334
+ rank orders the ability of a person to walk 10m after
335
+ a spinal cord injury from most to least severe
336
+ impairment (Ditunno & Dittuno, 2001).
337
+
338
+ American Spinal Injury Assessment (ASIA)
339
+ motor and sensory scores
340
+ The ASIA Impairment Scale builds on the earlier
341
+ Frankel scale, but includes a number of significant
342
+ improvements. The International Standards for
343
+ Neurological Classification of Spinal Cord Injury
344
+ (ISNCSCI) were developed by the American Spinal
345
+ Injury Association (ASIA) as a universal classi-
346
+ fication tool for spinal cord injury (SCI), depending
347
+ upon motor and sensory impairment that results from
348
+ a SCI. It assesses Functional Mobility, Strength and
349
+ Upper Extremity Function. A tapered piece of cotton
350
+ and a safety pin is required to administer the test,
351
+ which usually takes 10-60 minutes (Furlan et al.,
352
+ 2008).
353
+
354
+ Modified Ashworth Scale to measure spasticity
355
+ Originally developed to assess the effects
356
+ of antispasticity drugs on spasticity in Multiple
357
+ Sclerosis. Modified Ashworth: measures spasticity in

359
+ Original Ashworth Scale: Tests resistance to passive
360
+ movement about a joint with varying degrees of
361
+ velocity scores range from 0-4, with 5 choices. A
362
+ score of 1 indicates no resistance and 5 indicates
363
+ rigidity. Modified Ashworth Scale: Similar to
364
+ Ashworth, but adds a 1+ scoring category to indicate
365
+ resistance through less than half of the movement.
366
+ Thus scores range from 0-4, with 6 choices
367
+ (Bohannon & Smith, 1987).

369
+ Anthropometry: Body Mass Index (BMI)
370
+ The body mass index (BMI), or Quetelet index, is
371
+ a measure of relative weight based on an individual’s
372
+ mass and height. It is defined as the individual’s body
373
+ mass divided by the square of their height – with the
374
+ value universally being given in units of kg/m2
375
+ (Eknoyan and Garabed, 2007).

+ Erythrocyte Sedimentation Rate (ESR)
381
+ An erythrocyte sedimentation rate (ESR) is a type
382
+ of blood test that measures how quickly erythrocytes
383
+ (red blood cells) settle at the bottom of a test tube that
384
+ contains a blood sample. Normally, red blood cells
385
+ settle relatively slowly. A faster-than-normal rate may
386
+ indicate inflammation in the body. Inflammation is
387
+ part of your immune response system. It can be a
388
+ reaction to an infection or injury. ESR can be marker
389
+ of altered immune response seen in people with SCI
390
+ (Edsberg, Jennifer, Rajna, et al., 2015).
391
+
392
+ Assessments
393
+ The assessments were done on day1 and day30.
394
+ Fasting blood was drawn from the study participants
395
+ early in the morning and send to the Institute’s
396
+ Pathology Lab to test for ESR. The Physical
397
+ Examination tests like MMAS and WISCI II were
398
+ carried out by an Expert Physiotherapist who was
399
+ blinded to the study design. MPI was filled by the
400
+ participants with the guidance of trained staff.

405
+ Multidimensional Pain Inventory (Spinal Cord
406
+ Injury Version) – MPI-SCI
407
+ A spinal cord injury version of the MPI that
408
+ assesses the severity and impact of chronic pain,
409
+ emotional and physical adaptation to persistent
410
+ pain, and social support. The internal consistency
411
+ of the MPI-SCI sub-scales ranged from fair (.60)
412
+ for affective distress to substantial (.94) for pain
413
+ interference with activities. With the exception of the
414
+ support and life control sub-scales, all others showed
415
+ adequate test-retest reliability. The MPI-SCI measures
416
+ impact of pain on activities of daily living, which
417
+ corresponds to achievements and activities of daily
418
+ living, and subjective evaluations and reactions of
419
+ Dijker’s Model. Each item is scored on a 7-point
420
+ scale. Scale scores are computed by summing over all
421
+ Monali Madhusmita, T. M. Srinivasan, John Ebnezar et al.
422

445
+
446
+ The specific module of ‘Integrated approach of
447
+ Yoga therapy (IAYT)’ for Spinal Cord injury
448
+ management was developed by using the concepts
449
+ from traditional yoga scriptures (Patanjali Yoga
450
+ Sutras, Upanishads and Yoga Vasishtha) that
451
+ highlights a holistic approach to health management
452
+ at physical, mental, emotional and intellectual levels.
453
+ The practices consisted of asana chosen specifically
454
+ for Spina Cord Injury (yoga postures), pranayama,
455
+ kriyas, relaxation techniques, Chanting of OM and
456
+ Mahamrytunjaya Mantra and yogic counselling for
457
+ stress management. The physical practices (spinal
458
+ cord injury special techniques) progressed from safe
459
+ yogic movements to yoga postures to provide traction
460
+ like effect and channelize the vital energy flow all
461
+ through the spine.

715
+ Discussion
716
+
717
+ This study aimed to compare the effect of add-on
718
+ of IY intervention to Physiotherapy, in the manage-
719
+ ment of spinal cord injury (SCI) patients. At the end
720
+ of one-month the study found significant reductions in
721
+ Variables: Erythrocyte Sedimentation Rate, Walking
722
+ index for SCIII (WISCI II), Multidimensional Pain
723
+ Inventory: MPI-S1, (MPI-S2), MPI-S3 and Modified-
724
+ Modified Ashworth Scale (MMAS).
725
+ The current study clearly shows that add-on of
726
+ IAYT was effective make the performance of YG was
727
+ better than WLC.
728
+ Mechanisms underlying the beneficial effects of
729
+ Yoga practice on spinal cord injury patients are not
730
+ yet well understood. Yoga represents a form of mind-
731
+ body fitness. IAYT includes a combination of asanas,
732
+ pranayama, meditation and relaxation, and internally
733
+ directed mental focus on awareness of self, breathing,
734
+ and energy (Rajashree, Hankey, Nagendra, Mohanty,
735
+ 2016). However, Muscle conditioning during yoga’s
736
+ intense stretching postures helps by improving
737
+ oxidative capacity and strength of skeletal muscles,
738
+ flexibility, endurance, coordination, power, static and
739
+ dynamic stability, decreasing glycogen utilization, in
740
+ turn improving physical performance and increasing
741
+ walking pace and stride length (Katiyar, Bihari,
742
+ 2006). This possibly explains for the improvement in
743
+ scores of Walking Index for SCIII (WISCI II), and
744
+ shows significant difference between the groups post
745
+ intervention.
746
+ MSRT technique leads to deep relaxation, which
747
+ helps in downregulating the hypothalamus-pituitary-
748
+ axis and reduces anxiety (Hewitt, 2009) and stress
749
+ (Robins, Hendin, Trzesniewski, 2001). By reducing
750
+ the activation and reactivity of the sympathoadrenal
751
+ system and the hypothalamic pituitary adrenal (HPA)
752
+ axis and promoting feelings of well-being, Yoga may
753
+ alleviate the effects of stress and bring up multiple
754
+ positive downstream effects on neuroendocrine status,
755
+ metabolic function and related systemic inflammatory
756
+ responses. These results may also explain the
757
+ improvements in pain in YG more than WLC
758
+ {Multidimensional Pain Inventory: MPI-S1, (MPI-
759
+ S2),
760
+ MPI-S3},
761
+ and
762
+ reduction
763
+ in
764
+ Erythrocyte
765
+ Sedimentation Rate (ESR) values which is highly
766
+ significant in YG.
767
+ Deep
768
+ relaxation
769
+ technique,
770
+ an
771
+ important
772
+ component of IAYT showed significant reductions in
773
+ the yoga group’s spasticity, possibly due to
774
+ modulation of cardiac autonomic function and
775
+ cardiorespiratory efficiency (Tomas, 2011). It may
776
+ also synchronize neural elements in the brain, leading
777
+ to
778
+ ANS
779
+ changes,
780
+ resulting
781
+ parasympathetic
782
+ dominance and blunted sympathetic activity leading
783
+ to reduced spasticity. Pranayama modifies various
784
+ inflatory and deflatory lung reflexes and interacts with
785
+ central neural elements to improve homeostatic
786
+ control (Tandon, Tripathi, 2012).
787

+
789
+ Cerebrospinal Fluid (CSF) and Traumatic
790
+ Spinal Cord Injury (TSCI)
791

795
+ 65
796
+ patients. These changes can be experimentally
797
+ evaluated ex vivo by isolating the CD34+ progenitor
798
+ stem cells from the CSF of the pre and post TSCI
799
+ patients. Any severe damage to CSF of these
800
+ TSCI patients may be reflected in the CD34+ stem
801
+ cells differentiation. Since the colony formation is
802
+ controlled by cytokines, these growth factor changes
803
+ may also be measured using ELISA, on the CSF of
804
+ the pre and post TSCI patients. Hence, whether
805
+ cytokine therapy could be considered for the TSCI
806
+ patients may be of relevance.
807
+
808
+
809
+ Scope and Limitations of the Study
810
+
811
+ This is the first randomized controlled study
812
+ of yoga for spinal cord injured patients with ASIA
813
+ score C and D (paraplegics). It used IAYT, and its
814
+ reasonable sample size offers good evidence for
815
+ the benefits of yoga-based rehabilitation. Having
816
+ additional subgroups stratified as motor and sensory
817
+ complete and incomplete would have made the
818
+ study more vigorous. In addition, we did not
819
+ investigate radiological findings, such as MRI, CT-
820
+ scan or X-rays, which would have detailed clearly
821
+ the clinical outcomes, providing a fuller picture of
822
+ subject’s
823
+ anatomy
824
+ and
825
+ physiology.
826
+ Similarly,
827
+ assessments
828
+ of
829
+ neurological
830
+ biomarkers
831
+ (e.g.,
832
+ neuroproteomics) in body fluids would throw light
833
+ on mechanisms. Objective measurement of bio-
834
+ energy fields of patients with GDV or BIOWELL
835
+ would also explore the positive changes in energy
836
+ state and mood. We would recommend a multicentre
837
+ RCT to confirm results of the study, with a longer
838
+ follow-up of 6 months or more to evaluate long-term
839
+ efficacy.
840

841
+
842
+ Conclusions
843
+
844
+ Present study indicated that addition of integrated
845
+ yoga intervention to physiotherapy have beneficial
846
+ effects in terms of improving pain, inflammation, gait
847
+ and spasticity among patients with paraplegia.
848
+ Further, this study also suggest the implementation of
849
+ yoga intervention in the conventional rehabilitation
850
+ program for traumatic spinal injury patients.

+ Background and Objectives: A major part of Diabetes burden (75%) will be borne by
19
+ developing countries and India will be having the dubious honour of being host to the
20
+ maximum number of diabetics numbering about 57 millions. Complementary and
21
+ Alternative Medicine (CAM) modalities are found to be effective in the management of
22
+ Diabetes Mellitus type 2. While Naturopathy and Yoga is a part of CAM which is used in
23
+ the management of Diabetes Mellitus type 2, the scientific literature to support its’
24
+ judicious usage is inadequate. Hence the present study evaluated the effect of
25
+ Naturopathy and Yoga on the Fasting blood glucose (FBG) and postprandial blood
26
+ glucose (PPBG) levels in patients with Type 2 Diabetes Mellitus.
27
+ Methods: Subjects were recruited from the Yoga and Naturopathy Hospital,
28
+ Shanthivana, Dharmastala, Karnataka. Two Hundred patients diagnosed for Diabetes
29
+ Mellitus type 2 were screened. One Hundred subjects were recruited for the single pre-
30
+ post design study, selected based on the inclusion and exclusion criteria. Subjects were
31
+ assessed for FBG and PPPG levels before and after 10 days of intervention.
32
+ Results: The results suggested the significant changes in the levels of FBG and PPBG
33
+ with the p <0.001.
34
+ Interpretation & Conclusion: Naturopathy and Yoga is one of the major treatment
35
+ modality in controlling type II Diabetes Mellitus.

+ INTRODUCTION
39
+ The prevalence of Type 2 Diabetes Mellitus (T2DM) is projected to rise from 171 million
40
+ in 2000 to 366 million in 2030(Wild, Roglic, Green, Sicree, & King, 2004). T2DM is a

47
+ costly, complex, chronic disease that is expected to increase in prevalence in the coming
48
+ decades(“Economic costs of diabetes in the U.S. in 2007.,” 2008). The estimated annual
49
+ cost of diabetes-related medical expenses was $132 billion in 2002, accounting for more
50
+ than 12 per cent of the U.S. health care budget(Hogan, Dall, & Nikolov, 2003). A major
51
+ part of Diabetes burden (75%) will be borne by developing countries(Arora MM,
52
+ Chander Y, Rai R,2000) and India has the second largest number (>61 million) of
53
+ individuals with T2DM in the world and this is expected to nearly double by
54
+ 2030(Brussels, 2011).
55
+ The prevalence of risk factors for diabetic complications, such as hypertension,
56
+ obesity, and physical inactivity are also high. In 2007 67.0% of United States adults with
57
+ diabetes reported having hypertension, 83.5% were overweight or obese, and 38.2%
58
+ reported 0 being physically inactive. Cardiovascular complications are the leading cause
59
+ of morbidity and mortality among patients with T2DM, and cardiovascular disease
60
+ (CVD) risk is 2 to 8 fold higher in the diabetic population than it is in non-diabetic
61
+ individuals of a similar age, sex and ethnicity(Haffner, Lehto, Rönnemaa, Pyörälä, &
62
+ Laakso, 1998)(Brun et al., 2000). Furthermore, macro vascular complications are the
63
+ largest contributor to the direct and indirect costs of diabetes(“Economic costs of diabetes
64
+ in the U.S. In 2007.,” 2008). Micro albuminuria and retinopathy are indicators of micro
65
+ vascular dysfunction, and both predict a poorer outcome in patients with diabetes(Rajala,
66
+ Pajunpää, Koskela, & Keinänen-Kiukaanniemi, 2000)(Klein, Klein, Moss, &
67
+ Cruickshanks, 1999).
68
+ Complementary and alternative medicine (CAM) may offer novel approaches to
69
+ address lifestyle,behaviour change for prevention and control of chronic diseases such as
70
+ T2DM.
71
+ Naturopathic medicine is of greatest interest as it is a whole-system of CAM most
72
+ closely resembling conventional primary care in scope of practice, but with greater
73
+ delivery of healthy lifestyle counselling(Bradley et al., 2009). According to observational
74
+ studies, healthy lifestyle interventions are routine in naturopathic clinical care for T2DM
75
+ ,with diet, physical activity, and stress management counselling incorporated into the
76
+ majority of clinical encounters (80– 100%)(Bradley & Oberg, 2006)(Bradley & Oberg,
77
+ 2006). Care provided by Naturopathic Doctors (ND) is a particularly promising form of
78
+ CAM practice for diabetes, because the ND training emphasizes assessment and
79
+ understanding of medical risk, intensive dietary and lifestyle counselling, and the routine
80
+ laboratory testing necessary for on-going management(Bradley & Oberg, 2006; Bradley
81
+ et al., 2011; Oberg, Bradley, Allen, & McCrory, 2011).
82
+ In a survey conducted in United States, approximately 48% of individuals with
83
+ diabetes reported using CAM. Several CAM modalities like naturopathy, acupuncture,
84
+ therapeutic massage, reflexology, dietetics etc. are found to be effective in the
85
+ management of T2DM( Donald Garrow, Leonard Egede E, 2006). Retrospective
86
+ observational studies also suggest ND care reduces risk for T2DM and hypertension,
87
+ including improved glucose control and reduced blood pressure, respectively(Ellen
88
+ seber,2000).

307
+ Previous studies have shown decrease in the levels of FPG, PPPG and HbA1c by
308
+ the intervention of Yoga, Diet and Naturopathic intervention. A clinical study has shown
309
+ that the Naturopathic care to people with T2DMsignificantly improved glycemic control,
310
+ increased self-monitoring of blood glucose, improved diet, increased physical activity,
311
+ greater self-efficacy, improved mood and reduced problem areas in diabetes(Bradley et
312
+ al., 2012).Another study demonstrates the modifications in risk-factors that occur with
313
+ long-term naturopathic care for T2DM with notable percentages of patients achieving
314
+ improvements in glucose levels as measured by HbA1c and blood pressure
315
+ measures(Bradley et al., 2009).
316
+ A retrospective study suggests Naturopathic medicine is a philosophy-based,
317
+ complete medical system. This description of naturopathic care can serve other health
318
+ professionals in their referral recommendations. Naturopathic care for diabetes at this
319
+ representative academic facility remains mostly adjunctive, although physicians possess
320
+ the training and skills necessary to participate as primary care providers.
321
+ The naturopathic treatment approach frequently includes important dietary and
322
+ lifestyle recommendations included in current medical treatment guidelines for diabetes,
323
+ hypertension, and hyperlipidaemia, although improvements can be made on the precision
324
+ of recommendations(Bradley & Oberg, 2006).
325
+ The present study also suggested the similar results of the previous study that the
326
+ Naturopathy and Yoga intervention reduces both Fasting blood glucose level and Post-
327
+ prandial glucose levels.
328
+ Limitation of the study:
329
+ • There is no control group in the study.
330
+ • Compared to other intervention based studies, the duration of this study is
331
+ considerably short.
332
+ • The study was limited to a fixed period of intervention. Post intervention follow
333
+ up was not done which is critical in evaluating a non-pharmacological therapy in
334
+ the management of a chronic disease like T2DM.
335
+ CONCLUSION
336
+ The present study suggested that Naturopathy and Yoga intervention has reduced
337
+ significantly the levels of FBG and PPBG in patients with Type II Diabetes Mellitus. The
338
+ Naturopathy and Yoga intervention is the main stream of management in treating Type II
339
+ Diabetes Mellitus.

51
+ Abstract
52
+ Context: Abnormal respiratory function is known to be detectable almost as soon as it can
53
+ be measured reliably. Studies have identified the effect of respiratory muscle training as well
54
+ as breathing exercises in improving pulmonary functions in children with Duchenne muscular
55
+ dystrophy (DMD). Aims: This study aims to identify the add‑on effect of yoga over physiotherapy
56
+ on pulmonary functions in children with DMD. Settings and Design: One hundred and twenty‑four
57
+ patients with DMD were randomized to two groups. Group I received home‑based physiotherapy and
58
+ Group II received physiotherapy along with yoga intervention. Materials and Methods: Pulmonary
59
+ function test  (PFT) was assessed before the intervention  (baseline data) and at regular intervals
60
+ of 3 months for a period of 1  year. Statistical Analysis Used: Normality was assessed using
61
+ Shapiro–Wilk normality test. The baseline data were analyzed using Mann–Whitney U‑test to
62
+ identify the homogeneity. Repeated measures analysis of variance was used to assess significant
63

+ an insight on the presence of subclinical pulmonary
148
+ dysfunction early in the course of disease that evolves later
149
+ into clinical dysfunction.[8] Abnormal respiratory function
150
+ is known to be detectable almost as soon as it can be
151
+ measured reliably. PFT should be performed on a regular
152
+ basis on patients diagnosed with DMD to understand the
153
+ prognosis and to initiate early interventions as required in
154
+ accordance with the indications identified.[8]
155
+ Various strategies have been adopted for respiratory
156
+ management in patients with DMD. One study has shown
157
+ that steroid treatment has the potential to stabilize lung
158
+ function in DMD patients even in nonambulant children,
159
+ in those older than 10  years, and in those in whom the
160
+ medication was started after 7  years of age.[2] The rate of
161
+ decline of FVC% has been reported to reduce from 4.28%
162
+ to 1.36% upon initiating noninvasive ventilation.[9] Chest
163
+ physiotherapy and respiratory muscle training are being
164
+ administered in DMD patients, but their efficiency is not
165
+ fully established. Studies have identified the effect of
166
+ respiratory muscle training as well as breathing exercises
167
+ in improving pulmonary functions in children with DMD.
168
+ Yeldan et al. have showed that respiratory muscle strength
169
+ is enhanced in ambulatory patients with DMD with
170
+ training.[10]
171
+ Yoga is a complimentary mind–body therapy which is
172
+ being practiced increasingly among Indian and Western
173
+ populations. An American survey in 2004 reported that 15
174
+ million adults used yoga at least once in their lifetime and
175
+ 7.4 million during the previous year, and concluded that
176
+ yoga was often helpful and cost effective.[11] It has been
177
+ proven that yoga as an add‑on therapy in patients with
178
+ DMD has an effect on heart rate variability.[12] Rodrigues
179
+ et  al. have identified that 83% of DMD patients are able
180
+ to learn how to perform yoga breathing exercises and
181
+ could significantly demonstrate improvements in forced
182
+ expiratory volume in 1 s (FEV1) and FVC over a period of
183
+ 10 months.[13] Yoga may help in improving the lifespan and
184
+ quality of living of DMD individuals through its influence
185
+ on pulmonary functions, which is least explored by
186
+ researchers. Although the effect of yoga and physiotherapy
187
+ has been studied separately, combined effect of both is not
188
+ known. Yoga which is a recent trend in the field of exercise
189
+ and fitness can be used as an adjunct with the regular
190
+ physical therapy program. This randomized trail aims to
191
+ identify the add‑on effect of yoga over physiotherapy on
192
+ pulmonary functions in children with DMD.
193
+ Materials and Methods
194
+ Participants
195
+ Children with a confirmed diagnosis of DMD were selected
196
+ for the study. Boys within the age group of 5–10 years and
197
+ who were self‑ambulant or required minimal assistance
198
+ were included for the study. The exclusion criteria were as
199
+ follows: muscular dystrophy other than DMD, nonambulant
200
+ children, children with DMD who were undergoing regular
201
+ yoga and physiotherapy before recruitment, children with
202
+ DMD who were on steroids for more than 3 months, and
203
+ associated cardiopulmonary conditions. Written informed
204
+ consent was obtained from the parents or guardians of the
205
+ children with DMD after explaining the nature and purpose
206
+ of the study.
207
+ Design
208
+ The study was conducted for a period of 4 years. The study
209
+ was approved by the Institutional Review Board of the
210
+ institution. The consort diagram explaining the procedure
211
+ of the study is depicted in Figure  1. The patients were
212
+ randomly allocated to two groups, i.e., Group I and Group
213
+ II, using computer‑generated Tippet’s random number table.
214
+ Assessments
215
+ The demographic data and medical history of the
216
+ patients were documented. PFT was assessed before the
217
+ intervention  (baseline data) and at regular intervals of 3
218
+ months for a period of 1  year, using the spirometry kit
219
+ manufactured by Microquark Cosmed, Italy. The procedure
220
+ was explained to the participants, and three measurements

+ FVC, PEFr, tidal volume, MVV, and tidal volume during
249

+ analysis.
251
+ Intervention
252
+ Group I received home‑based physiotherapy exercises for
253
+ two sessions a day: one in the morning and another in
254
+ the evening. Group II received one session of yoga in the
255
+ morning and one session of physiotherapy in the evening
256
+ as home program. Each session of physiotherapy and yoga
257
+ lasted for a maximum of 45  min. The detailed protocol
258
+ of physiotherapy and yoga is provided in Tables  1 and 2,
259
+ respectively.
260
+ Participants were made to practice physiotherapy and yoga
261
+ under the supervision of physiotherapists initially for a
262
+ period of 1  week. Parents were also trained during these
263
+ supervised sessions in order to enable them to conduct
264
+ sessions at home. Patients were then asked to perform the
265
+ exercises every day at home for a period of 1 year. All the
266
+ parents were instructed to maintain an exercise diary which
267
+ was reviewed every 3 months at the time of each visit for
268
+ the assessment during which the home program performed
269
+ by the children was also reviewed.
270
+ Data analysis
271
+ Outcome measures for the study were assessed at 5
272
+ points of time during the study period  (baseline, at 3
273
+ months, 6 months, 9 months, and after 12 months). All
274
+ the variables were tested for normality using Shapiro–
275
+ Wilk normality test. The baseline data of Group I and
276
+ Group II were also analyzed using Mann–Whitney U‑test
277
+ to identify the homogeneity between the groups. Repeated
278
+ measures analysis of variance  (RmANOVA) was used
279
+ to assess significant changes in study parameters during
280
+ the assessment of every 3 months, both within and
281
+ between the two groups of patients. Time effect  (changes
282
+ over the duration of treatment irrespective of type of
283
+ treatment), group effect  (difference between the treatment
284
+ groups irrespective of the time point of assessment), and
285
+ interaction effect (differences in the way the two treatment
286
+ groups differ at the five time points of assessment) were
287
+ also identified. Post hoc test was carried out using least
288
+ significant difference test. The mean difference between
289
+ the baseline and 1‑year follow‑up data of the individuals
290
+ was also analyzed according to the age groups of 5–6, 7–8,
291
+ and 9–10 years of age. The data were analyzed using  IBM

294
+ Results
295
+ A total of 124 boys with DMD fulfilling the inclusion
296
+ criteria were recruited and were followed for 1  year at
297
+ an interval of 3 months for a total of 5 serial follow‑up
298
+ assessments  (including baseline). The patients were
299
+ randomly grouped into Group I  (physiotherapy treatment
300
+ regimen)  (n  =  62) and Group II  (physiotherapy and yoga
301
+ treatment regimen)  (n  =  62). Thirty‑six  (30%) individuals
302
+ dropped out from the study  (17  (57%) from Group I and
303
+ 19  (63%) from Group II) at different time intervals and
304
+ 88 participants  (71%) completed all the 5 assessments.
305
+ The mean age of individuals recruited for study was
306
+ 7.9  ±  1.5  years. The mean height was 118.2  ±  8.4 cm
307
+ (ranges between 95 and 147 cm) and the mean weight was
308
+ 20.6  ±  4.3 kg  (ranges between 11 and 32 kg). The mean
309
+ age of onset of the disorder was 2.8  ±  0.6  years  (ranges
310
+ between 1.5 and 4.0  years). The mean duration of illness
311
+ within the population was 5.1  ±  1.5  years  (ranges from 1
312
+ to 8 years).
313
+ A comparison performed between the two groups on
314
+ baseline PFT parameters showed no significant changes
315
+ between them, thus maintaining homogeneity at the initial
316
+ time period of the study  [Table  3]. Serial evaluation
317
+ of PFT parameters was carried out at baseline and
318
+ after intervals of every 3 months for 1  year  [Table  4].
319

363
+ Discussion
364
+ This randomized comparative study aimed at comparing
365
+ the effect of physiotherapy and physiotherapy with yoga
366
+ in children with DMD to improve pulmonary functions.
367
+ The mean age of onset of the study population was
368
+ 2.8 ± 0.6 years, which is similar to other studies conducted
369
+ within the same population.[14,15] The results suggest that,
370
+ except for tidal volume, all other parameters of PFT
371
+ have significantly improved on the course of treatment
372
+ irrespective of the intervention provided. It is also
373
+ noteworthy that there is no significant difference between
374
+ the two groups based on the intervention administered at
375
+ any point of the timeframe of follow‑up visits.
376
+ The skeletal muscle tissue undergoes wasting and is
377
+ ultimately replaced by fat and fibrotic tissue as the disease
378
+ progresses. In the later stage of the disease, weakness
379
+ of the diaphragm reduces the respiratory efficiency that
380
+ in turn leads to decrease in ventilation.[16‑18] Expiratory
381
+ lung strength begins to decline at the age of 7  years and
382
+ continues to worsen with age.[16] Thirty percent of children
383
+ with DMD had a history of respiratory complications, and
384
+ the frequency increased with age.[4] DMD patients may
385
+ develop respiratory failure due to restrictive respiratory
386
+ pattern. Pulmonary function increases until 10–12  years
387
+ of age and reaches plateau, following which it declines at
388
+ rate of 6%–8% annually. Vital capacity shows 10.7%/year
389
+ decrease in DMD children.[2]
390
+ FVC is one of the best indicators of clinical condition of
391
+ the lungs.[19] Expiratory muscles are more affected than
392
+ inspiratory muscles in children with DMD, leading to
393
+ a reduced quality of cough. This can cause ineffective
394
+ removal of secretions and an increased chance of
395
+ infections.[20] Previous studies in nonambulatory patients
396
+ have found that FVC declines rapidly when standing
397
+ ceases. A percentage of FVC was found to be the parameter

+ than 80% of predicted as early as 7  years of age.[20,21] As
740
+ this disease has a characteristic stage‑wise deterioration,
741
+ a planned and proactive approach to respiratory care is
742
+ advocated and appropriate surveillance, prophylaxis, and
743
+ intervention are needed.
744
+ Effect of physiotherapy on pulmonary functions
745
+ Physiotherapy improves muscle strength, reduces the
746
+ progression of joint contractures and spinal deformity,
747
+ improves respiratory functions, prolongs ambulation
748
+ for as long as possible, and maintains the best level of
749
+ health.[22,23] Topin et  al. suggested that specific training
750
+ improves respiratory muscle endurance in DMD and
751
+ the effectiveness of training appears to be dependent on
752
+ the quantity of training.[24] In our study when compared
753
+ to baseline values, with PT intervention, FVC, MVt,
754
+ PEFr, and MVV significantly improved from baseline
755
+ to 1  year. FVC and MVV are important parameters
756
+ of PFT which are reflective of the intercostal and
757
+ diaphragm muscle strength. Hence, the intervention has
758
+ helped in improvement/maintenance of muscle strength
759
+ of the respiratory muscles. PEFr also improved after
760
+ physiotherapy which suggests that there was an increase
761
+ in the flow of oxygen into the bronchioles and hence
762
+ increased ventilation.
763
+ Various methods are used in the treatment of DMD to
764
+ improve respiratory function. This includes respiratory
765
+ muscle training, resisted inspiratory muscle training
766
+ using valves, breath stacking with resuscitation bags,
767
+ and glossopharyngeal breathing.[25] These methods need
768
+ specialists’ presence along with some equipment needed
769
+ all the time. Chances of development of fatigue and
770
+ further deterioration of respiratory muscles are another
771
+ complication
772
+ of
773
+ vigorous
774
+ respiratory
775
+ training.[25]
776
+ In
777
+ comparison to this, yoga which is a holistic approach is
778
+ relatively simple to follow at home with little training,
779
+ providing maintenance as well as improvements in the
780
+ disease course.
781
+ Effect of yoga on pulmonary functions
782
+ Practice of yoga in the form of low‑intensity rhythmical
783
+ movements with mindfulness is known to improve
784
+ the coping skills with physical and emotional stresses
785
+ effectively.[26] The yoga asanas are done with mindfulness
786
+ to achieve both physical and mental well‑being and
787
+ harmony. We have used the holistic approach suitable
788
+ for DMD children and included Sukshma and Sthula
789
+ Vyayama  (low‑exertion exercises), breathing exercises,
790
+ Pranayama and Kriyas with awareness and relaxation,
791
+ asanas, and guided meditation. Six weeks of Pranayama
792
+ practice in healthy volunteers have found to reduce
793
+ respiratory rate and increase FVC, FEV1%, MVV and
794
+ PEFR.[27] Similar beneficial effects were observed by
795
+ Makwana et  al., after 10  weeks of yoga practice, with
796
+ increase in inspiratory and expiratory pressures which
797
+ suggests that yoga training improves the strength of
798
+ respiratory muscles.[28]
799
+ Overall relaxation and calming the mind through physical
800
+ and breathing practices is the primary goal of yogic
801
+ practices. Yoga in the form of Pranayama has an effect on
802
+ limbic system, hypothalamic medullary axis, and medullary
803
+ cardiovascular centers, which might have influenced
804
+ the cardiorespiratory system.[29] Pranayamas also help
805
+ in increasing respiratory capacity, whereby helping to
806
+ suspend respiratory cycle for a longer duration with lesser
807
+ effort.[30] One of the studies showed that Pranayama and
808
+ meditation added along with regular physiotherapy in adult
809
+ patients with neurological disorder showed improvement in
810
+ the quality of sleep.[31] Yoga has neurocardiac beneficiary
811
+ effect by reducing vagal tone as well as reducing the
812
+ catecholamine,
813
+ angiotensin
814
+ II
815
+ concentrations,
816
+ and
817
+ increasing bioavailability of nitric oxide.[12] Slow yoga
818
+ breathing decreases chemoreflex responses to hypoxia, and
819
+ hypercapnia in healthy practitioners with increased FVC
820
+ and PEFr after 3 months of practice.[32]
821
+ The study observed significant improvements in the PFT
822
+ parameters on the course of treatment irrespective of the
823
+ intervention provided. The improvements were steady and
824
+ more pronounced in younger children. Yoga intervention
825
+ showed significant improvements in the pulmonary function
826
+ parameters such as FVC and MVt after 1  year, whereas
827
+ MVV showed a significant improvement from baseline up
828
+ to 9 months. There are certain advantages of using yoga
829
+ as a therapeutic intervention in children with DMD. Yoga
830
+ asanas in which the thorax and spinal movements are used,
831
+ there is a natural movement occurring in the costovertebral
832
+ joints of the thorax and the ribs.[33] This movements
833
+ can maintain the mobility in the thoracic cage which is
834
+ essential for prevention of the reduced compliance of the
835
+ cage in the due course. In our study, thoracic spine and
836
+ rib cage movement is evident by means of Vakrasana and
837
+ Bhujangasana.
838
+ Comparing yoga and physiotherapy on pulmonary
839
+ functions
840
+ No studies are available which have evaluated the effect
841
+ of yoga on serial assessment of PFT in DMD. In our
842
+ study, we observed that FVC, MVV, and MVt improved
843
+ significantly at every 3‑month follow‑up and were sustained
844
+ for a period of 1  year with combined therapy with yoga
845
+ and physiotherapy. In our study, the abnormalities in PFT
846
+ parameters indicated subclinical pulmonary dysfunction
847
+ as none of the patients demonstrated any respiratory
848
+ symptoms. This may evolve later in to clinical respiratory
849
+ dysfunction, which makes it imperative to start respiratory
850
+ muscle training early in the disease course to slow down its
851
+ progression.
852
+ These evidences collectively show that physiotherapy
853
+ and
854
+ yoga
855
+ practices
856

863
+ function by increasing the respiratory muscle strength,
864
+ maintaining the resilience of lung tissue, and improving
865
+ the lung capacities. Based on these objective evidences
866
+ of the effect of yoga on pulmonary functions, the same
867
+ could be extrapolated to explain the improvements
868
+ noted in PFT parameters in our study population. As the
869
+ pulmonary dysfunctions are subclinical in DMD children,
870
+ it is imperative to assess pulmonary functions at an early
871
+ age and introduce appropriate interventions which will
872
+ offer higher benefit in improving pulmonary functions
873
+ through which assisted ventilation may be delayed in
874
+ the disease course by which the life expectancy may be
875
+ expanded.
876
+ Conclusions
877
+ The early introduction of a pulmonary rehabilitation
878
+ protocol helped in maintaining and improving the
879
+ pulmonary functions in patients with DMD. Our findings
880
+ provide evidence that yoga has an add‑on effect along with
881
+ physiotherapy intervention at an early age, which can be
882
+ considered as one of the therapeutic strategies in improving
883
+ pulmonary functions in children with DMD.

+ Abstract
18
+ Context:
19
+ HIV/AIDS individuals have problems relating to immune system, quality of life (QOL), and cognitive
20
+ functions (CFs). Yoga is found to be useful in similar conditions. Hardly, any work is reported on yoga
21
+ for HIV-positive adults/adolescents. Hence, this study is important.
22
+ Aim:
23
+ The aim of the study is to determine the effect of yoga on immune parameters, CFs, and QOL of HIV-
24
+ positive children/adolescents.
25
+ Settings and Design:
26
+ Single-group, pre–post study with 4-month yoga intervention.
27
+ Methods:
28
+ The study had 18 children from an HIV/AIDS rehabilitation center for children/adolescents. CD4,
29
+ CD8, CD4/CD8 ratio, and viral loads were studied. CF tests included six letter cancellation test,
30
+ symbol digit modalities test, digit-span forward backward test, and Stroop tests. QOL was assessed
31
+ using PedsQL-QOL and fatigue questionnaire. Depression was assessed using CDI2-SR.
32
+ Statistical Analysis Used:
33
+ t-test and Wilcoxon signed-rank tests, as applicable.
34
+ Results:
35
+ The study included 18 children/adolescents. There was improvement in general health of the
36
+ participants. There was statistically significant increase in CD4 cells counts (p = 0.039) and significant
37
+ decrease in viral load (p = 0.041). CD4/CD8 ratio moved to normal range. QOL significantly
38
+ improved. CFs had mixed results with improved psychomotor performance (PP) and reduced executive
39
+ functions.
40
+ Conclusions:
41
+ There was improvement in general health and immune parameters. While depression increased, QOL
42
+ improved. CFs showed mixed results with improved PP and reduced executive functions.

44
+ Introduction
45
+ HIV/AIDS still remains to be one of the challenging and prevailing diseases of the modern times. The
46
+ HIV/AIDS individuals have issues with general health owing to poor immune system leading to several
47
+ opportunistic infections. The quality of life (QOL) is also rated to be poor among HIV/AIDS adults[1]
48
+ and is attributed to reasons such as stigma, depression, and cultural beliefs.[2,3] Depression and
49
+ cognitive disorders are also a prevalent comorbid mental disorders in HIV positives.[4,5,6,7]
50
+ Depression is reported in up to 45% of HIV/AIDS patients.[8] Bhargav et al.[9] have reported that
51
+ yoga could promote the health of HIV-infected mothers, enhance the efficacy of antiretroviral therapy
52
+ (ART) in preventing vertical progression of HIV (mother-to-child transmission of HIV), and help
53
+ reduce ART-related side effects. The mechanisms of action explained in the report also indicate that
54
+ yoga would help any HIV-positive individual in general. Other reports also show that yoga helps in
55
+ improving immune system functioning.[10] Bhargav et al.[11] describe the importance and mechanism
56
+ of working of yoga on HIV-positive individuals and also recommend a theoretical comprehensive yoga
57
+ module for HIV positives. However, they do not provide any empirical evidence. In spite of the clue
58
+ that yoga can improve immune functioning, not many studies are reported on immune parameters in
59
+ specific owing to the cost of blood tests.[12] A pilot randomized controlled trial study reports that 1-
60
+ month yoga intervention showed improvement in CD4 count and depression among adult age group.
61
+ [13] Yet, another single-group pre–post study has shown improvement in immunity, depression, and
62
+ anxiety management of HIV adults.[14] Yoga has shown improvement in cognitive functions (CFs) of
63
+ normal school children.[15] Yoga, in general, is known to also helpful in alleviating depression and
64
+ improving QOL in several diseased conditions.[13] However, there are hardly any reports on the effect
65
+ of yoga on children/adolescents with HIV. The current study is an attempt to determine the effect of
66
+ yoga practice on the immune system, CFs, and QOL of HIV-positive children/adolescents.
67
+ Methods
68
+ This study is a part of larger study to determine the effect of yoga on the immune system, CFs, and
69
+ QOL of HIV-positive children/adolescents. The design is a single-group pre–post study conducted on
70
+ HIV-positive children/adolescents in an HIV/AIDS rehabilitation center (RC). The RC had 22
71
+ children/adolescents, both males and females, at the time of the start of the study. Although all 22 were
72
+ included in the study, for CF tests where the ability to read English was inevitable, only such of those
73
+ having the appropriate abilities had to be considered. Further, for answering questionnaires, assistance
74
+ was provided to the participants in the local language by research volunteers. Four participants had left
75
+ the RC at the time of final data collection, and hence, the net number of participants were 18. The RC
76
+ had voluntarily provided consent for the study.
77
+ The yoga intervention largely based on a potential yoga module for HIV-positive individuals[11]
78
+ included 1-h daily practice primarily involving loosening and breathing exercises, āsanas
79
+ (Sūryanamaskāra - six rounds, Padmāsana, Vajrāsana, Varvāṇgāsana, Bhujangāsana, Ardhakati
80
+ Ćakrásana, Uśtrāsana, Ardha Ćakrásana, Paśćimottanāsana, and Shavāsana) and prāṇāyāma
81
+ (Kapālabāti (Kriya), Bhāstrika, Nāḍiśodhana, and Brāmari). Yoga was taught by a professional yoga
82
+ teacher. Duration of intervention was 6 months. The daily routine of the participants was not disturbed,
83
+ except for one hour yoga. Routine medical care too was not disturbed, and all the participants
84
+ continued the standard medical care and checkups as per norms/schedules. All the participants were
85
+ under the first-line ART routine as part of the standard medical care.
86
+ For the study of immune parameters, health status, and related issues, the data were collected from the
87
+ medical files proactively maintained by the RC as per norms. CD4 and CD3 counts and viral load were
88
+ available. CD8 counts were computed using the formula CD8 = CD3 − CD4, and the CD4/CD8 ratio
89
+ was calculated. Health-related QOL (HRQOL) was assessed with the help of PedsQL QOL
90
+ questionnaire which has four subscales, namely, (a) health and general activities, (b) feelings, (c)
91
+ getting along with others, and (d) about school. Fatigue-related QOL (FRQOL) was assessed through
92
+ the PedsQL fatigue questionnaire which has three subscales (a) general fatigue (b) sleep fatigue, and
93
+ (c) cognitive fatigue. The depression level of the candidates was assessed through self-reported child
94
+ depression inventory, version 2 (CDI2-SR) questionnaire. The CFs were assessed through digit-span
95
+ forward-backward (DSFB) test, symbol digit modalities test (SDMT), six letter cancellation test
96
+ (SLCT), and Stroop test (ST). While SLCT and SDMT test for the psychomotor performance (PP),
97
+ DSFB and ST test the executive functioning (EF) aspect of CF. Standard test procedures were used for
98
+ the assessment in all tests. The statistical programming language R3.5.0 (with appropriate add-on
99
+ packages) was used, and suitable codes were written for statistical computations and for graphical
100
+ representation of data. t-test and Wilcoxon signed-rank test (WSRT) were used for determining the
101
+ differences in the parameters for data with normal distribution and not with normal distribution,
102
+ respectively.
103
+ Results
104
+ Sociodemographic data
105
+ The participants included 18 children/adolescents of age between 8 and 18 years. The mean age was
106
+ 13.5 ± 2.46 years (mean ± standard deviation). Of 18 participants, 14 were males and 4 were female.
107
+ General health
108
+ At the beginning of the study, the participants had several opportunistic infections and health issues,
109
+ namely, skin infection, eye, and ear problems, all of which were significantly reduced at the time of
110
+ final data collection. These general health conditions are as reported by the physician during routine
111
+ medical checkup.
112
+ Immune parameters
113
+ The mean CD4 cell counts significantly increased from 571.1 ± 238.0 cells/mm before yoga to 717.4
114
+ ± 241.7 cells/mm after yoga (p = 0.039), with typically the values at the baseline being in tune with
115
+ that reported by an earlier study.[9] The average CD8 cell counts decreased from 1389.18 ± 572.88
116
+ cells/mm before yoga to 1338.82 ± 471.12 cells/mm after yoga, which was not statistically
117
+ significant (p = 0.477, WSRT). Mean CD4/CD8 ratio increased from 0.814 to 1.016 although the
118
+ median difference between pre- and post-values was not statistically significant (p = 0.091; WSRT).
119
+ The average viral load significantly reduced from 55487.5 ± 56996.4 copies/mL before yoga to 5755.4
120
+ ± 6539.3 copies/mL after yoga (p = 0.041; WSRT). Table 1 shows the summary of the immune
121
+ parameters along with the general medical issues. Figures 1 and 2 show the distribution of CD4 and
122
+ viral load, respectively, along with the change in the parameters case to case between pre- and post-
123
+ yoga.

333
+ The CDI2-SR-T scores were calculated as per the guidelines are given in the CDI-SR user manual.[16]
334
+ Results revealed that the average of the total CDI-T-scores significantly increased from 55.7 ± 8.42
335
+ before yoga to 61.1 ± 10.33 after yoga (p = 0.029). Similarly, all the subscales and the sub-subscales
336
+ showed increase in the average T-scores. This means that the depression has increased. CDI2-SR
337
+ classifies depression status into four categories, (1) very elevated, (2) elevated, (3) high average, and
338
+ (4) average or lower.[16] Although there is an increase in the depression of the children, it has only
339
+ moved from higher range of lower depression state (lower depression range = 40–59) to lower range of
340
+ high depression range (high depression range = 60–64). Both raw scores and T-scores indicated similar
341
+ performance. Table 3 shows the summary of the results of various CDI parameters.

513
+ Discussion
514
+ There has been a significant improvement in the general health condition of the participants, as
515
+ reported by the physicians during their routine checkup. Skin infection in the participants is either
516
+ reduced or nullified in all the participants. For want of control group in the study, the improvement
517
+ cannot be attributed purely to yoga intervention. However, sūryanamaskāra, kapālabāti (Kriya),
518
+ bhāstrika, and nāḍiśodhana prānāyāma in the yoga intervention are known to be excellent practices for
519
+ participants having skin diseases.[17] Hence, yoga could have played a role in improving the status.
520
+ The major point that was demonstrated through this study is that there was improvement in the immune
521
+ parameters. The CD4 cells are the major marker for HIV/AIDS increased by 36.63% which is also
522
+ statistically significant. Further, at the baseline, the counts were well matching with the ones reported
523
+ in one of the earlier studies. The CD4/CD8 ratio improved by 42.05%. The normal CD4/CD8 ratio is
524
+ 1–4[18] and the average ratio shifted from a lower value (0.814) to normal (1.016), also indicating
525
+ improvement in the immune system. This is further supported by the decrease in the viral load by an
526
+ average of 178.5%. Figure 3 shows the relationship between changes in viral load against changes in
527
+ CD4. It can be observed that in most the cases where there is a massive drop in the viral load, they are
528
+ characterized by large increase in the CD4 cell counts.
529
+ Figure 3
530
+ Case-wise relation between viral load and CD4 cell counts, pre and post yoga intervention
531
+ The case-to-case observation indicated that yoga greatly helped those participants whose viral loads
532
+ were very high. It can be noted that participants with a viral load >18,000 cells/mm showed a more
533
+ significant decrease in viral load (p = 0.018, WSRT). Considering such cases, the CD4 counts and
534
+ CD4/CD8 ratio cell count increased although not significantly (p = 0.128 and p = 0.063, WSRT).
535
+ Overall, it can be noted that yoga has helped candidates even with high levels of viral loads. Perhaps,
536
+ yoga seems to have an attribute of addressing the crucial problems first by prioritizing. Although in this
537
+ study, the changes in immune parameters cannot be completely attributed to yoga program since this
538
+ study does not have a control group; another 1-month yoga intervention study reports that there is a
539
+ significant increase in CD4 cell counts among adults against the control group.[13] Thus, this study
540
+ shows that yoga can help to HIV positives in increasing the CD4 cells and reducing the viral load in
541
+ children/adolescents. However, there was no change in ART status recommended by the physicians.
542
+ In the current study, there was mixed response to CFs. SLCT showed improvement in the result.
543
+ Normative data for SLCT on healthy school children indicate a mean score of 24.04, for the age group
544
+ of 9–16 years.[19] In the current study, the mean scores were 23.4 and 27.6 before and after yoga,
545
+ respectively. Thus, at the baseline, the scores were lesser than that of normal and improved to normal
546
+ after yoga. Similarly, SDMT also showed significant improvement (p~0). DSFB test which is a test for
547
+ EF showed a nonsignificant improvement. Stroop tasks which also require good working memory and
548
+ is a test of EF[20] also showed show improvement but not significant. Thus, in the current study, CFs
549
+ pertaining PP showed significant improvement while that of EF did not. With reference to DSFB test
550
+ while the participants showed improvement in DSB, there was difficulty with DSF test. Supporting this
551
+ phenomenon, another study on large group of children with specific learning disabilities also showed
552
+ similar results which are attributed to more requirement of working memory in DSF than in DSB.[20]
553
+ It is also known that depression has a negative impact on working memory,[21] thus resulting in poor
554
+ executive function. Incidentally, in the current study, the participants' depression level also showed an
555
+ increase. Overall, the current study could not improve EFs of the participants owing to depression
556
+ which also could not be improved.
557
+ 3
558
+ There was an overall significant improvement in the QOL although not statistically significant in all the
559
+ subscales. The physical functioning score had good significance since yoga is known to improve the
560
+ flexibility of the body. The fatigue factors assessed through the PedsQL fatigue questionnaire also
561
+ showed improvement. Of the three subscales, sleep/rest fatigue showed significant improvement.
562
+ However, although not statistically significant, there was improvement in general fatigue and cognitive
563
+ fatigue subscales. Improvement in sleep/rest fatigue state is an important aspect since HIV-positive
564
+ individuals are known to have issues in sleep.[6]
565
+ CDI total score had increased significantly (p < 0.05). The total score comprises emotional problem
566
+ (EP) and the functional problem (FP). Of these, the increase in EP is statistically significant (p =
567
+ 0.039), and FP is not statistically significant (p = 0.082). EP has two components, negative mood
568
+ physical symptoms (NMPSs) and negative self-esteem (NSE). Of these, NMPS is not statistically
569
+ significant (p = 0.887>>0.05), whereas NSE has a high statistical significance (p~0). Thus, the
570
+ participants have statistically significant NSE. Looking into the components of NSE in the
571
+ questionnaire, it can be understood that there is a need to address the issues such as “things not working
572
+ out well with” (Q.2r [question 2; r indicating reverse scoring]), “blaming themselves for the faults that
573
+ happen” (Q.7r), and “sometimes being disgusted” (Q.8). However, for the participants, “liking
574
+ themselves” (Q.6r) was not an issue although they had an issue about “somebody else loving them”
575
+ (Q.24r). This means that in the current study, yoga could not address these issues but largely physical
576
+ issues.
577
+ Similarly, FP has two sub components ineffectiveness (INE) and interpersonal (IP). The IP has no
578
+ statistical significance (p = 0.571). However, with INE, there is a statistically significant increase (p =
579
+ 0.032). A detailed analysis of the INE reveals through the component questionnaire that there are issues
580
+ with “making up mind to do things” (Q.12r), “having fun at school” (Q.20r), and “feeling good relative
581
+ to others” (Q.23). It can also be noted that the participants on an average that they do have any issues
582
+ with “having fun” (Q.4) in general (although not at school), “to make time to do school-related things”
583
+ (Q.14r, Q.22), and “remembering things” (Q.28). Although the EF tests indicated poor working
584
+ memory, CDI is not sensitive to tap the difference between different types of memories. However, this
585
+ also explains the improvement in other CFs which require memory. The component on issues related to
586
+ going to school has been positive in spite of it being a component of INE which had overall negative
587
+ effect. This is further supported by the improvement in the school functioning subscale of PedsQL
588
+ QOL questionnaire. Overall, the yoga program needs to be improved to address psychosocial issues,
589
+ which can be improved with the addition of yogic games which help children involve better with others
590
+ and proper counseling.
591
+ Conclusions
592
+ In the current study, the six months yoga program could significantly improve the immune parameters
593
+ of the HIV-positive children/adolescents. CD4 and viral load significantly improved, with CD4 cells
594
+ increasing and viral load reducing. CD4/CD8 ratio moved to a normal range. Yoga could also improve
595
+ the QOL of the children/adolescents. In an overall sense, yoga could not improve, in the current study,
596
+ the depression of the children/adolescents. However, several sub components of the depression showed
597
+ improvement or were not affected. With reference to CFs, PP improved while executive functions did
598
+ not improve owing to depression among the participants. The major issue is with mentally preparing
599
+ the children/adolescents to think more positively about themselves. Improvement in the yoga program
600
+ by introducing yogic games, more of prānāyāmas, and the introduction of counseling could improve
601
+ the situation.

+ Abstract
19
+ Background: Type 2 diabetes mellitus (T2DM) is a highly prevalent disease characterized by
20
+ chronic hyperglycemia. Yoga is a form of mind-body intervention shown to have a positive
21
+ impact on several health conditions in both healthy and diseased patients. The present study
22
+ is intended to assess the effects of the Residential Integrated Yoga Program (RIYP) on blood
23
+ glucose levels in patients with T2DM. Material and Methods: Data of 598 (186 females) T2DM
24
+ patients from a holistic health center in Bengaluru, India, who attended a 15-day RIYP between
25
+ January 2013 and December 2015 was obtained retrospectively. Average age of the partici­
26
+ pants was 56.45 ± 11.02 years. All subjects underwent a 15-day RIYP which involved yoga-
27
+ based lifestyle changes with components of regulated sleep, balanced diet, asanas, pranaya­
28
+ ma, relaxation techniques, meditations, yogic cleaning procedures, and tuning to the nature.
29
+ Fasting and post-prandial blood sugar, medication score, symptom score, systolic and diastol­
30
+ ic blood pressure, pulse rate, and respiratory rate were assessed before and after intervention.
31
+ Result: There was a significant decrease in fasting (p < 0.001) and post-prandial blood sugar
32
+ levels (p < 0.001) along with a significant reduction in medication and symptom scores after
33
+ 15 days of RIYP compared to baseline. Conclusion: The present study indicates that 2 weeks
34
+ of a yoga-based residential program improves blood glucose levels, blood pressure, and med­
35
+ ication score in patients with T2DM. However, further randomized controlled studies need to
36
+ be performed in order to confirm the present findings.

+ Introduction
59
+ Type 2 diabetes mellitus (T2DM) is a common metabolic disorder characterized by chronic
60
+ hyperglycemia. It is a leading cause of morbidity and mortality worldwide, associated with
61
+ severe complications such as cardiovascular disease, cerebrovascular disease, or chronic renal
62
+ disease. It is projected to be the 7th leading cause of death by 2030 [1]. The worldwide preva­
63
+ lence of T2DM was estimated to be 6.4%. In Asia, 15% of the population – or 1 in 7 adults –
64
+ have been reported to have either elevated fasting glucose or impaired glucose tolerance [2],
65
+ 5–12% of these persons develop type 2 diabetes every year [3]. At present, India is the country
66
+ with the 2nd highest number of T2DM patients, and the figure is expected to double by 2030
67
+ [4]. The incidence rate of T2DM cases is progressively increasing in rural parts of India, and
68
+ the age at onset of T2DM is also reducing gradually [5, 6] due to unhealthy lifestyles [7].
69
+ Conventional anti-diabetic medication therapy includes oral administration of hypogly­
70
+ cemic agents and insulin therapy. These methods have been shown to be beneficial in the
71
+ initial phase of T2DM; over a period of time, however, a significant number of patient reports
72
+ indicate a reduced efficacy of most anti-diabetic medications. Further, these medications are
73
+ associated with several adverse effects including weight gain [8, 9] weakness, fatigue, lactic
74
+ acidosis, or diarrhea, and they may increase LDL cholesterol level. Vigorous insulin treatment
75
+ may also carry an increased risk of atherogenesis [10, 11].
76
+ Yoga is a form of traditional and complementary medicine. Several scientific investiga­
77
+ tions have shown the health-benefiting effects of yoga in various chronic health conditions
78
+ including T2DM [12], neuromuscular diseases [13], psychiatric illnesses [14], asthma [15],
79
+ hypertension [16], and coronary artery disease [17].
80
+ Material and Methods
81
+ From a holistic health center in Bengaluru, India, data of 598 (186 females) T2DM patients, with on
82
+ average 8 ± 3.4 years of history of T2DM and who attended a 15-day yoga program between January 2013
83
+ and December 2015, was obtained retrospectively.
84
+ Inclusion and Exclusion Criteria
85
+ Subjects with T2DM, within the age range of 30–60 years, who meticulously followed the routine of
86
+ Integrated Approach of Yoga Therapy (IAYT) for 15 days during their stay at the health center, were
87
+ considered for the study. Subjects were excluded from the study if they were on insulin therapy, had any
88
+ diabetic complications, were on antipsychotic medication or steroid medication, were long-term practi­
89
+ tioners of any kind of yoga, or had been practicing yoga within the last year.
90
+ All subjects underwent a 15-day Residential Integrated Yoga Program (RIYP) which involved timetable-
91
+ based, supervised, yoga-based lifestyle changes with components of regulated sleep, yogic sattvic diet,
92
+ asanas, pranayama, relaxation techniques, meditations, yoga-based cleansing procedures, lectures on yoga
93
+ philosophy, and selfless service. All subjects were assessed before and after intervention for changes in
94
+ fasting blood sugar, post-prandial blood sugar, medication score, and symptom scores along with systolic and
95
+ diastolic blood pressure, bhramari time, pulse rate, and respiratory rate.
96
+ Ethical Considerations
97
+ This study was approved by the institution’s Ethics Committee of SVYASA University, Bengaluru, India.
98
+ Intervention
99
+ The RIYP which is based on IAYT can be understood as a holistic model, which corrects imbalances at
100
+ the physical, mental, and emotional level through the application of multiple components such as asanas, diet,
101
+ loosening exercise, breathing exercises, pranayama, cyclic medication, mind sound resonance technique,
102
+ devotional sessions, and yogic counseling (lectures). For details on time tables followed during the 15 days
103
+ of RIYP, see Table 1 and 2.

111
+ Data was analyzed using IBM SPSS software, version 10. Paired-sample t test was applied to assess
112
+ changes from pre- to post-RIYP in all variables. Data was presented in the form of mean and standard devi­
113
+ ation. Statistical change with a p value < 0.05 was considered as a significant change.

192
+ Discussion
193
+ The present study showed a significant improvement in blood glucose levels, physio­
194
+ logical variables, and anti-diabetic medication score following 15 days of RIYP in patients
195
+ with T2DM. This suggests a potential role of RIYP in T2DM management. Yoga-based lifestyle
196
+ intervention is a comprehensive intervention and consists of several physical and mental
197
+ practices. Yoga is also cost effective and easy to maintain, requiring little in the way of
198
+ equipment or professional personnel, and there is evidence indicating excellent long-term
199
+ adherence and benefits.
200
+ A randomized controlled trial by Nagarathna et al. [18], in 2012, showed a significant
201
+ reduction in oral hypoglycemic medication requirement and LDL; and increasing HDL, blood
202
+ glucose, HbA1c, triglyceride, total cholesterol, and VLDL following a yoga-based lifestyle
203
+ modification program.
204
+ In our study, T2DM patients stayed for 15 days during which the RIYP for diabetes was
205
+ imparted to them. Yoga-based lifestyle takes into consideration the 5 important factors of
206
+ lifestyle: (1) diet, (2) physical activity, (3) sleep, (4) habits, and (5) psychological stress. The
207
+ designed RIYP was developed to address each of these lifestyle factors and bring balance at
208
+ all the levels. Medication compliance and adherence to yoga was controlled by the medical
209
+ doctor and yoga therapist in charge at the section; diet was controlled as standard sattvic food
210
+ was provided; the location of our health home – being away from city life and amidst nature
211
+ – could be considered as a calming factor to combat stress.
212
+ Many previous studies have shown beneficial effects of yoga in improving overweight,
213
+ blood pressure, insulin levels, triglycerides [19], fasting and post-prandial blood sugar levels,
214
+ and pulse rate [20, 21]. Most of the above-mentioned studies where yoga therapy was bene­
215
+ ficial in reducing blood sugar levels involved yoga intervention of discrete yoga sessions
216
+ (asanas, paranayama, or both) in the usual routine (mostly for 60 min per day, 1–5 days per

+ study of the scriptures, and yogic counseling) are integrated together on the basis of the
290
+ philosophy of yoga-based lifestyle then they may act synergistically and thereby provide
291
+ better results than those produced by any of the components of yoga alone.
292
+ The improvement in fasting and post-prandial blood sugar levels following IAYT may be
293
+ attributed to an activation of the HPA axis through a reduction in stress which is associated
294
+ with decreased glucose levels in T2DM. Several sessions of yoga in a day may help the patients
295
+ to improve their glucose level.
296
+ Though the present retrospective study was performed on a large number of T2DM
297
+ subjects, the lack of a control group is a major limitation of the current study. Future studies
298
+ should use a control group, where subjects follow a conventional lifestyle change program in
299
+ a residential setup and then compare the residential conventional lifestyle change program
300
+ with the residential yoga-based lifestyle program (RIYP).
301
+ Conclusion
302
+ The present study indicates that 2 weeks of yoga-based residential program improves
303
+ blood glucose levels, blood pressure, and medication score in T2DM patients.

+ Effect of high-frequency yoga breathing on pulmonary functions in
3
+ patients with asthma
4
+ A randomized clinical trial
5
+ Bronchial asthma is one of the most common respiratory disorders
6
+ with significant morbidity and mortality. Patients with asthma
7
+ experience declined lung function. Among patients with asthma,
8
+ forced expiratory volume in 1 second (FEV1), forced vital capacity
9
+ (FVC), and FEV1/FVC ratio were found to be lower than in age- and
10
+ height-matched healthy individuals.1 To arrest the decline in
11
+ ventilatory function is one of the major objectives of management
12
+ of asthma.
13
+ Yoga has been used to manage asthma in several clinical trials. A
14
+ recent Cochrane review found yoga useful in alleviating symptoms
15
+ of asthma and improving the quality of life.2 However, there is lack
16
+ of empirical studies on the effect of specific yoga practices on lung
17
+ functions in patients with asthma.
18
+ Kapalabhati is a technique described in the traditional texts of
19
+ yoga indicated for phlegm-related diseases, such as bronchial
20
+ asthma and other respiratory disorders.3 The practice of kapa-
21
+ labhati has been found to enhance pulmonary functions.4 It has also
22
+ been used in combination with other yoga practices for asthma in
23
+ most earlier clinical trials.5,6 We evaluated the immediate effects of
24
+ kapalabhati on lung function among patients with mild and mod-
25
+ erate asthma, comparing it with deep breathing with breath
26
+ awareness.
27
+ This was a single-center, randomized, prospective, controlled
28
+ study performed at an inpatient yoga and naturopathy facility from
29
+ South India. After screening 78 patients with clinician-diagnosed
30
+ asthma, 60 patients were recruited for the study. A total of 35
31
+ men and 25 women, with the mean (SD) age of 31.5 (8.23) years,
32
+ were included in the study. We included patients from the age
33
+ group of 20 to 50 years to restrict the study population to adults.
34
+ Patients with severe asthma (predicted FEV1 60%) and any other
35
+ respiratory disorders that influence pulmonary function or a prior
36
+ history of abdominal or thoracic surgery were excluded from the
37
+ study. Individuals with a history of tobacco smoking were excluded
38
+ because smoking exacerbates symptoms and restrict the lung
39
+ functions. The demographic data of the subjects are given in Table 1.
40
+ All the patients were trained in the practice of kapalabhati for a
41
+ period of 10 min/d for 1 week before they were randomly assigned
42
+ to different groups.
43
+ The patients were randomly assigned to experimental (18 men
44
+ and 12 women) and control (17 men and 13 women) groups
45
+ using random numbers generated by a computer-based program
46
+ (www.randomizer.org) with a 1:1 ratio. The protocol of the study
47
+ was reviewed and approved by the institutional ethics committee
48
+ of the SDM College of Naturopathy and Yogic Sciences, Ujire,
49
+ India. Informed written consent was obtained from each patient
50
+ before the commencement of the intervention.
51
+ The practice of kapalabhati included breathing at 1 Hz in which
52
+ the exhalations are kept as an intentionally active process. The
53
+ participants were asked to sit in cross-legged position, keeping the
54
+ back erect. On the assessment day, the experimental group practiced
55
+ kapalabhati for10 minutes. The practicewas repeated, giving abreak
56
+ of half a minute between 2 bouts of practice. The control group
57
+ practiced deep breathing at 6 breaths per minute for the same
58
+ duration, maintaining awareness on the nostrils. The assessments
59
+ were performed before and immediately after the practice.
60
+ On the day of assessment, the patients were asked to evacuate
61
+ the bowels and bladder and restrain from consuming food for at
62
+ least
63
+ 2
64
+ hours before
65
+ recording.
66
+ The
67
+ participants
68
+ were also
69
+ restrained from the use of all bronchodilators for at least 24 hrs
70
+ before assessment. Spirometry was performed using the BIOPAC
71
+ MP36 system (www.biopac.com). Three recordings were averaged
72
+ to obtain the values of FEV1 (liters), FVC (liters), and FEV1/FEC ratio.
73
+ The data were analyzed using SPSS statistical software, version
74
+ 16 (SPSS Inc, Chicago, Illinois). The means of preintervention and
75
+ postintervention values in each group were analyzed using the
76
+ paired-samples t test, and the between-group comparisons for the
77
+ postintervention
78
+ values
79
+ were
80
+ made
81
+ using
82
+ the
83
+ independent-
84
+ samples t test. The data were found to be normally distributed
85
+ (Shapiro-Wilk
86
+ test).
87
+ The
88
+ within-group
89
+ analyses
90
+ revealed
91
+ a
92
+ significant increase in FEV1 (1.91 [0.31] to 2.12 [0.35]; t ¼ 8.149; P
93
+ < .001), FVC (2.62 [0.68] to 2.70 [0.57]; t ¼ 2.438; P < .05) and
94
+ FEV1/FVC ratio (0.75 [0.12] to 0.80 [0.10]; t ¼ 4.232; P < .001) in
95
+ the kapalabhati group. None of the variables had a significant
96
+ change in the deep breathing group. The between-group analyses
97
+ revealed a significant difference between the postintervention
98
+ values of FEV1 (t ¼ 2.319, P < .05) and FEV1/FVC ratio (t ¼ 2.173,
99
+ P < .05). The results are summarized in Table 2.

141
+ The current study indicates a significant increase in lung func-
142
+ tions immediately after the 10-minute practice of kapalabhati
143
+ among the patients with bronchial asthma. There were no signifi-
144
+ cant changes observed in the deep breathing group. In addition, a
145
+ significant difference was observed between the 2 groups in the
146
+ FEV1 and FEV1/FVC ratio after the intervention. A mean increase of
147
+ approximately 200 mL in FEV1 was observed in a single session of
148
+ kapalabhati for just 10 minutes. During the trial, none of the
149
+ patients reported any untoward effects attributable to the practice.
150
+ They found the practice comfortable and reported fewer episodes
151
+ during the training phase, although we did not systematically
152
+ record the same. Thus, this preliminary trial found the practice of
153
+ kapalabhati
154
+ an
155
+ easy-to-perform
156
+ and
157
+ cost-effective
158
+ means
159
+ of
160
+ enhancing lung function.
161
+ Inconsistent results are reported on the effects of breathing
162
+ practices in patients with asthma.7 To the best of our knowledge,
163
+ this was the first systematic attempt to examine the immediate
164
+ effects of kapalabhati in patient with asthma. The results concur
165
+ with the earlier yoga studies reporting beneficial effects of yoga
166
+ practices.2
167
+ Parasympathetic dominance plays an important role in the
168
+ pathophysiology of bronchial asthma.8,9 Earlier studies have indi-
169
+ cated sympathetic activation after the practice of kapalabhati.10,11
170
+ One of the postulated mechanisms of action for the observed
171
+ effects in the study could possibly be immediate sympathetic
172
+ activation after the practice of kapalabhati. Future trials may
173
+ include measures of autonomic functions to understand whether
174
+ sympathetic activation is the background mechanism.
175
+ The practice of yoga breathing may also increase the lungs
176
+ capacity and decrease the airway resistance. Forceful expiration, as
177
+ practiced in kapalabhati, may lead to efficient use of the intercostal
178
+ and diaphragmatic muscles, leading to better lung functions. The
179
+ part of
180
+ kapalabhati
181
+ that involves
182
+ isometric
183
+ contraction
184
+ and
185
+ expansion of abdominal and intercostal muscles may also improve
186
+ the strength of the intercostal muscles and thus lead to increased
187
+ FVC and FEV1. We speculate this increase in FEV1 will lead to
188
+ a
189
+ transient
190
+ increase
191
+ in
192
+ the
193
+ muscle
194
+ tone
195
+ immediately after
196
+ kapalabhati. The increase in FVC is suggestive of a probable role of
197
+ kapalabhati in enhancing the oxygen-carrying capacity of the red
198
+ blood cells and overall respiratory muscle endurance.
199
+ Although
200
+ this
201
+ study
202
+ found
203
+ significant
204
+ improvements
205
+ in
206
+ lung functions immediately after the practice of kapalabhati, the
207
+ long-term effect of the practice in the patients remains to be esti-
208
+ mated. There is also a need for further evaluation of the effects of the
209
+ practice on the overall functional status in patients with asthma.
210
+ Hence, we conclude that kapalabhati might be an effective
211
+ intervention to improve pulmonary function among patients with
212
+ bronchial asthma. The practice of kapalabhati, being simple and
213
+ cost-effective, can be adapted easily by the patients. Further clinical
214
+ trials to estimate the long-term effects and underlying mechanisms
215
+ of effect of kapalabhati on pulmonary function are warranted.

+ EFFECT OF INTEGRATED YOGA AND PHYSICAL THERAPY ON AUDIO-
204
+ VISUAL REACTION TIME, ANXIETY AND DEPRESSION IN PATIENTS WITH
205
+ CHRONIC MULTIPLE SCLEROSIS: A PILOT STUDY
206
+ ABSTRACT
207
+ Background: Multiple Sclerosis is characterized by a significant deterioration in auditory and
208
+ visual reaction times along with associated depression and anxiety. Yoga and physical
209
+ therapy interventions have been found to enhance recovery from these problems in various
210
+ neuro-psychiatric illnesses, but sufficient evidence is lacking in chronic MS population.
211
+ Aim: To assess the effect of Integrated Yoga and Physical therapy on audio-visual reaction
212
+ times, depression and anxiety in patients suffering from chronic multiple sclerosis.
213
+ Material and Methods: From a Neuro-rehabilitation center in Germany, eleven patients (6
214
+ females) suffering from multiple sclerosis for 19±7.4 years were recruited. Subjects were in
215
+ the age range of 55.45±10.02 years and had Extended Disability Status Scores (EDSS) below
216
+ 7. All the subjects received mind-body intervention of Integrated Yoga and Physical therapy
217
+ (IYP) for three weeks. The intervention was given in a residential setup. Patients followed a
218
+ routine involving yogic physical postures, pranayama and meditations along with various
219
+ physical therapy techniques for 21 days, five days a week, 5 hours per day. They were
220
+ assessed before and after intervention for changes in audio-visual reaction times (using Brain
221
+ Fit model No OT 400), anxiety and depression (using HADS). Data was analysed using
222
+ paired samples test.
223
+ Result: There was significant improvement in visual reaction time (p = 0.01), depression (p =
224
+ 0.04) and anxiety (p = 0.02) scores at the end of 3 weeks as compared to the baseline.
225
+ Auditory reaction time showed reduction with borderline statistical significance (p = 0.058).
226
+ Conclusion: This pilot project suggests utility of IYP intervntion for improving audio-visual
227
+ reaction times and psychological health in chronic MS patients. In future, randomized
228
+ controlled trials with larger sample size should be performed to confirm these findings.
229
+ Key words: Multiple sclerosis, yoga, physical therapy, reaction time, anxiety, depression.

+ INTRODUCTION
297
+ Multiple sclerosis (MS) is a chronic inflammatory and autoimmune neuro-degenerative disorder
298
+ with emotional, cognitive, and physical consequences. Patients may display a diverse array of
299
+ symptochronic MS including impaired mobility, sensory disturbance, chronic pain, fatigue,
300
+ bladder and bowel dysfunction, depression, and cognitive impairment. Patients report high levels
301
+ of stress, independent of physical disability [1-3].
302
+ Patients with chronic MS have a defect in aspects of central auditory processing with
303
+ poorer hearing thresholds and increased auditory reaction times [4]. chronic MS patients have
304
+ been shown to have abnormalities in auditory evoked potentials indicating dysfunction of
305
+ different regions of the central auditory nervous system [5]. Optic pathway involvement
306
+ in multiple sclerosis is frequently the initial sign in the disease process [6]. Retinal nerve fiber
307
+ layer (RNFL) thickness is reduced in chronic MS cases and is associated with reduced visual
308
+ reaction times [7]. Visual impairment from axonal degeneration is increasingly recognized as
309
+ correlate of disability in chronic MS [8-10]. For treating chronic MS several pharmacological
310
+ drugs are available. Use of these drugs is limited due to their side effects a n d benefits are
311
+ also not satisfactory [11].
312
+ Stress is a potential trigger of disease activity in patients with relapsing-remitting
313
+ chronic MS. There are a few studies that point to the impact of stress on chronic MS.
314
+ Psychological stress has been implicated in the onset and exacerbations of several
315
+ autoimmune diseases including chronic MS [12]. Anecdotal accounts suggest
316
+ that
317
+ significant stressful life events frequently trigger the development of chronic MS
318
+ symptochronic MS. Psychological stress has been shown to precede both the onset and
319
+ recurrence of chronic MS symptochronic MS in 70-80% of cases, using standardized
320
+ assessment of life stressors measures[13]. More recently, stressful life events have been
321
+ shown to predict the development of new lesions and relapses in chronic MS [14]. Meta-
322
+ analyses concerning stress and chronic MS have concluded that there was a significantly
323
+ increased risk of exacerbation associated with stressful life events [15, 16]. The risk of
324
+ developing stress-related disorders like anxiety and depression is also high in chronic MS
325
+ patients with lifetime prevalence of 25% and 34–50% for anxiety and depression
326
+ respectively[17-20].

+
394
+ Yoga has gained popularity in health care systechronic MS as a mind-body intervention to
395
+ alleviate both mental and physical problechronic MS [21]. Yoga has already been proven to
396
+ incur various health benefits in chronic MS patients [22].Yoga has been found useful in
397
+ psychological disturbances such as anxiety and depression. It can be a viable therapeutic option
398
+ for reducing state anxiety [23]. Yoga could be an ancillary treatment option for patients with
399
+ depressive disorders and individuals with elevated levels of depression [24-25].
400
+ Yoga therapy has also been found useful in improving visual and auditory functions in patients
401
+ suffering from various chronic stress-related disorders. Certain yoga practices (OM meditation
402
+ and ujjayi pränäyäma) facilitate processing of auditory information at mesencephalic and
403
+ diencephalic levels [26-27]. Yoga practices improve visual perception as well [28-29] There are
404
+ studies showing that after practicing Yoga the auditory and visual reaction time decreased
405
+ significantly [30-32]. Slow and fast pranayama were particularly useful in improving auditory
406
+ and visual reaction times [33]. Yoga based intervention is beneficial for improving several
407
+ domains of cognitive function including processing speed, executive function, visual memory
408
+ and attention of the elderly [34].
409
+
410
+ Yoga therapy is superior to physical exercises because of its holistic approach. Yoga has been
411
+ proven useful in treating auto-immune diseases like Rheumatoid arthritis and
412
+ other
413
+ psychosomatic ailments. Yoga techniques such as äsanäs (postures), prāṇāyāma: (voluntary,
414
+ regulated breathing through nostrils), yoga nidrä (guided relaxation with imagery) and
415
+ meditation promote physical wellbeing and mental calmness. Various studies have shown its
416
+ effects in stress-related disorders, respiratory allergies, depression, anxiety neurosis, diabetes,
417
+ coronary heart disease, and rehabilitation of disabled [35]. Also, studies have shown that yoga
418
+ will help in improving the quality of life, disability limitation, and rehabilitation of people with
419
+ chronic diseases [36]. Different kinds of Yoga techniques intervention have shown positive
420
+ outcomes in chronic MS population. Yoga has been found useful in decreasing pain, fatigue [37-
421
+ 38], bladder dysfunction [39], improving balance, strength, peak expiratory flow [40], cognition
422
+ [41], anxiety and depression [42] and quality of life [43-44] of chronic MS Patients.

490
+ Physical therapy (PT) is another mode of treatment found effective in managing certain aspects
491
+ of chronic MS disease. PT intervention includes therapy using mechanical force and movement
492
+ which are aimed at alleviating impairments and promoting mobility, function, and quality of life
493
+ of patients. A course of physical therapy is associated with improved mobility, subjective
494
+ wellbeing, and improved mood in chronic multiple sclerosis [45]. Evidence supports that
495
+ exercise training is associated with improvement in walking mobility among individuals [46].
496
+ Physical rehabilitation resulted in an improvement in disability and had a positive impact on
497
+ mental components of health-related quality of life perception at 3 and 9 weeks [47]. Neuro-
498
+ rehabilitation has been shown to ease fatigue, bladder and bowel disturbances, sexual
499
+ dysfunction, cognitive and affective disorders, and spasticity symptochronic MS by improving
500
+ self-performance and independence [48].
501
+
502
+ Thus, present study was planned as an preliminary pilot attempt to assess the effect of intergrated
503

+ METHODOLOGY
586
+ Subjects
587
+ From a Neuro-rehabilitation center in Germany, eleven patients (6 females) suffering from
588
+ multiple sclerosis for 19±7.4 years were recruited. Subjects were in the age range of 55.45±10.02
589
+ years and had Extended Disability Status Scores (EDSS) below 7. Inclusion criteria for the study
590
+ were: 1) Those who satisfied Mc Donald’s diagnostic criteria for chronic MS [49]; 2) Those
591
+ suffering from chronic MS (MS for more than 5 years) with EDSS<or=7; 3) Those who gave
592
+ written consent to participate in the study; 4) Those who had not been exposed to regular (for at
593
+ least a month in last 1 year) Yoga therapy practices before and 5) Those using chronic MS
594
+ disease modifying drugs. Whereas those who were not capable of following yoga-instructions
595
+ mentally and physically; those suffering from transmittable infections, advanced dementia,
596
+ severe heart insuffiency (EF less than 35%) or on Artificial cardiac pace maker and COPD and
597
+ those with h/o substance abuse, any other organic brain illness or severe psychological morbidity
598
+ except anxiety and depression were excluded from the study.
599
+ Single group pre-post design was followed. All the subjects received mind-body intervention of
600
+ IYP for three weeks. They were assessed before and after intervention for changes in audio-
601
+ visual reaction times (using Brain Fit model No OT 400), anxiety and depression (using HADS).
602
+ Data was analysed using paired samples test. Signed, informed consent was obtained from the
603
+ subjects to participate in the study after explanations of protocol of the study. The approval from
604
+ the Institutional Review Board was taken.
605
+ INTERVENTION
606
+ The intervention was given in a residential setup. Patients followed a routine involving yogic
607
+ physical postures, pranayama and meditations along with physical therapy rehabilitation for 21
608
+ days, five days a week, 5 hours per day. The intervention included yoga and physical therapy
609
+ consisting of regular integrated yoga program (asanas, pranayama, relaxation techniques and
610
+ meditaions) given 5 days a week for 1 hour daily and Physiotherapy for 5 days a week, 3 hour
611
+ daily. Total intervention was given for 20 days. Data was taken on day 1 and day 21.

+ Integrated Approach of Yoga Therapy Module for chronic MS
680
+ Based on our 20 years of experience in dealing with chronic MS patients the following module
681
+ of IAYT was considered most useful (Table 1). Hence used for the study. Yoga therapy
682
+ techniques correct the problem from the most fundamental level. The corrections are sought
683
+ from the innermost causal layer of our existence (Ānandamaya kośa or the soul or the master of
684
+ the system). A total correction of the bodily disturbances is brought about by correcting
685
+ the disturbances at the emotional, psychological and the vital energy levels. The integrated
686
+ approach uses several techniques with a unique aim of reaching a state of silence or calmness
687
+ of mind or deep relaxation and rest. The special yoga module was designed by yoga
688
+ professionals of S-VYASA using basic principles of ancient yoga science and comprised the
689
+ following practices (The daily routine included one hour of group yoga practice); see Table
690
+ 1 [50-51]:
691
+ Loosening and strengthening exercises: These are Yogic loosening practices (sukshma
692
+ vyayamas) which help to stretch and loosen the body parts. This practice is done with
693
+ synchronising body movements and breathing.
694
+
695
+ Asanas: Yogasanas are the particular postures of the body. It includes stretching the body and
696
+ maininting the posture as per the capacity of individual or for a given duration of time with
697
+ awareness of breath and body.

700
+ Kriya:
701
+ According
702
+ to
703
+ ancient
704
+ scriptures,
705
+ Kriyas are the
706
+ cleansing
707
+ techniques.
708
+ Kapalabhati, a kriya stimulates brain cells and gives it the deep rest. Kapalabhati Kriya was
709
+ given to the patients once a day for 5 minutes.
710
+
711
+ Pranayama: Pranayama is a voluntary regulated breathing while the mind is directed to the
712
+ flow of breath. A cycle of the slow type Pranayama involves the phases of inhalation and
713
+ exhalation. There are different kinds of Pranayama which vary according to the durations of
714
+ the phases in the breathing cycles and the nostrils used. Yogic breathing practices were
715
+ included to bring about a slow rhythmic breathing pattern to reduce the breath rate with

+ internal awareness of the touch of the flow of air through the air passages, which is an
783
+ effective way to get mastery over the mind (Dr. H. R. Nagendra, 2000). Practice of Pranayama
784
+ promotes autonomic balance through mastery over the mind. Nadishuddi is a widely
785
+ practiced pranayama [50-51]
786
+
787
+ Relaxation techniques: It begins by slowly sliding down to shavasana with the support of the
788
+ elbows. Legs, hands are kept apart with palms facing the roof. The whole body is allowed to
789
+ collapse on the ground and part by part each portion of the body is relaxed from toes to head.
790
+
791
+
792
+ Counseling: Yogic concepts of health and disease, role of mind in the development of chronic
793
+ MS and healing property of mind are discussed.These sessions are aimed to understand the
794
+ need for life style change, and prevent the relapses by yogic self-management of psychosocial
795
+ stresses.
796
+ Physical Therapy for Multiple Sclerosis
797
+ Physical therapy intervention included therapies using mechanical force and movement aimed
798
+ towards remediation of impairments and promoting mobility, function, and quality of life.
799
+ Physical Therapies were given 5 days a week for 3 hours/day. Total intervention was given for
800
+ 20 days. Table 2 describes the physical therapy module. The program followed was as follows:
801
+ Active and passive movements using devices: Movement trainer helps to move the arms and legs
802
+ slowly. As per the muscle strength, patients selected either passive, motor-assisted or active
803
+ resistive training. The movements are smoothly controlled, as like bicycling. Depending on the
804
+ model, we can train patients on a chair, on a wheelchair or even in supine position from the bed.
805
+ It optimizes the motor assistance as per the individual need.
806
+ Galileo vibration therapy [52]: It is based on the use of a device called “Galileo XS”. The
807
+ device produces a large number of vibrations, it help to improve co-ordination of movements.
808
+ This method has been used successful in orthopedic patients and neurological patients. It

877
+ Giger therapy: By lying on back Giger MD enables the patient to move his limbs in a safe and
878
+ painless way. Though limbs are paralyzed or have reduced function after stroke or due to chronic
879
+ MS. If coordination and range of movement are reduced due to spasticity or immobilization, Bu
880
+ using bandages and belts the therapist will be able to place the patients’ arms and legs in the
881
+ correct position. Giger MD helps in improving motor function and co-ordination. Also, gentle
882
+ rotation of the arms and legs may also affect the trunk and thus relieve pain in the joints and the
883
+ spine.
884
+ Ergometer: It is an exercising machine which measures the work performed by exercising. It is
885
+ an instrument for measuring the amount of work done by body muscles and also used for to
886
+ increase the power of muscles.
887
+ Physiotherapy [53]: It builds on all traditional approaches, Using different manual therapy
888
+ techniques, several forms of electrotherapy, equipment-assisted therapy, therapeutic climbing,
889
+ massages etc. It helps to reduce balance problems, fatigue, weakness.
890
+ Matrix rhythm therapy[54]: It may be applied after operations and in rehabilitation. It helps to
891
+ decrease pain and improves symptoms of muscle and skeletal diseases. It uses oscillations to
892
+ produce resonance in the skeletal muscles. The oscillations are generated by a device are applied
893
+ to muscle fibres in specific therapeutic position. When matrix rhythm therapy is combined with
894
+ physiotherapy, it stimulates tight, spastic or even paralysed muscles to improve mobility of limb
895
+ and trunk functions and also provide targeted pain relief.

+ before and after the intervention. It was observed that there was significant improvement in
1065
+ visual reaction time (p = 0.01; -32.89 %), depression (p = 0.04; -41.51%) and anxiety (p = 0.02; -
1066
+ 32.09%) scores at the end of 3 weeks as compared to the baseline. Auditory reaction time
1067

1068
+ DISCUSSION
1069
+ Previously, in a randomised controlled trial, 150 chronic MS paitients were randomly divided
1070
+ into two groups : 1) Mindfulness based intervention and 2) Usual care. Intervention was given
1071
+ for eight weeks period and follow up was done after 6 months. Depression was measured with
1072
+ the center for epidemiologic studies depression scale (CES-D) and Anxiety with spielberger trait
1073
+ anxiety inventory pre and post intervention. It was found that depression, fatigue, and anxiety (P
1074
+ = .002) reduced significantly in mindfulness intervention group as compared to usual care and
1075
+ benefit continued upto 6 months. In another study, thirty-one chronic MS patients, all female
1076
+ with mean of age of 36.75 years and Expanded Disability Status Scale scores (EDSS) of 1.0 to
1077
+ 4.0 were recruited. Subjects were randomly assigned to one of the three groups: treadmill
1078
+ training, yoga or control groups. Treadmill training and yoga practice consisted of 8 weeks (24
1079
+ sessions, thrice weekly). The control group followed their own routine treatment program.
1080
+ Balance, speed and endurance of walking, fatigue, depression and anxiety were measured by
1081
+ Berg Balance scores, time for 10m walk and distance for a two minute walk, Fatigue Severity
1082
+ Scale (FFS), Beck Depression Inventory (BDI) and Beck Anxiety Inventory (BAI),
1083
+ respectively[57].Comparison of results showed that pre- and post-interventions produced
1084
+ significant improvements in the balance score, walking endurance, FFS score, BDI score and
1085
+ BAI score in the treadmill training group and yoga group as compared to controls. In this study,
1086
+ BDI scores decreased in the treadmill training group by 34.11%; whereas BAI score reduced by
1087
+ 78%. In the yoga practice group, average BDI score and BAI score decreased by 36.11% and
1088
+ 48.56%, respectively. In our study, we have found that using HADS, depression scores reduced
1089
+ by 41.51% and anxiety scores reduced by 32.09%. This shows that a yoga and physical
1090
+ intervention of 3 weeks may produce equivalent result of what is achieved through yoga therapy
1091
+ or other mindfulness based intervention in 8 weeks. This is probably due to synergistic effect of

1158
+ yoga therapy with other physical therapies involved in yoga and physical therapy. These findings
1159
+ are similar to what we have found in the present study using yoga and physical interventions. No
1160
+ previous study has assessed the effect of alternative or complementary therapies on Audio-Visual
1161
+ reaction times before in chronic MS patients and ours is the first attempt to explore this area.
1162
+ After the practicing of certain yoga techniques (OM meditation and ujjayi pränäyäma)measuring
1163
+ by the recordings of middle latency auditory evoke potentials, yoga practices facilitate the
1164
+ processing of auditory information at mesencephalic and diencephalic levels[58-59]. Yoga
1165
+ Practices improves visual perception as well[60-61] This may be the mechanism behind
1166
+ enhancement of audio-visual reaction times through Yoga therapy. Also, Yoga therapy may lead
1167
+ to increase in GABA (gamma-amino butyric acid) in the brain which may contribute towards
1168
+ anti-anxiety and anti-depressant effects[62-63]. Similarly, another study found positive
1169
+ therapeutic and neurotropic effects of yoga in depressive subjects. It was observed that a key
1170
+ modulator of neoplastic changes called brain derived neurotrophic factor (BDNF) levels
1171
+ increased after 3 months with positive correlation with fall in Hamilton Depression Rating Scale
1172
+ (HDRS)[64].
1173
+ Strengths of the present study are: a) First study assessing effects of IYP intervention in chronic
1174
+ MS patients; b) Procedures were simple and standardized modules were used; c) Study addressed
1175
+ an important aspect of chronic MS disease; d) Both the genders were included and e) Relatively
1176
+ longer duration of intervention was given; f)As patients followed a residential program, close
1177
+ monitoring was possible.
1178
+ Present study is a preliminary pilot attempt to understand and assess effect of combined yoga and
1179
+ physical therapy and has several limitations: a) Small sample size; b) lack of control group;
1180
+ c)Lack of robust objective variables of neuroimaging and biochemistry that would help
1181
+ understands the mechanisms involved.
1182
+ Future studies should be conducted by including control group, with bigger sample size and
1183
+ longer duration of intervention using randomized controlled design. Outcome measures
1184
+ may include other Audio-Visual testing variables to strengthen the evidence for the
1185
+ efficacy of Integrated Mulitmodal Therapy. Objective measure of neuroimaging and
1186
+ biochemical markers can be assessed in future studies. Effect of each therapy involved in
1187
+ Yoga and physical therapy can be assessed separately.

1255
+ CONCLUSION
1256
+ We conclude that Yoga is a feasible, easy and useful practice to improve visual reaction time and
1257
+ psychological health in Multiple Sclerosis. However, due to the limited number of participants
1258
+ and the lack of a control group further studies are necessary to confirm these results.
1259
+ ACKNOWLEDGEMENT
1260
+ We are thankful to KWA Klinik Stift Rottal Bad Griesbach, Germany for their support to conduct
1261
+ study. We are thankful to the participants who participated in the study.

+ Objective: To study the effect of integrated yoga on Pregnancy experience, anxiety, and depression in
27
+ normal pregnancy.
28
+ Methods: This Prospective Randomized control study recruited 96 women in 20th week of normal
29

32
+ Results: There was significant difference between groups (ManneWhitney p < 0.001) in all variables.
33
+ There were significant changes within groups (Wilcoxon’s p < 0.001) in both groups. Pregnancy related
34
+ experience (PEQ) reduced in yoga by 26.86%, State (STAI I) anxiety (decreased 15.65% in yoga, increased
35
+ 13.76% in control), Trait (STAI II) anxiety (decreased 8.97% in yoga, increased 5.02% in control) and
36
+ Depression (HADS) (decreased 30.67% in yoga, increased 3.57% in control).

+ 1. Introduction
40
+ Pregnancy is a unique state of physiological stress, which ne-
41
+ cessitates physical, mental and social adaptation. Animal experi-
42
+ ments and human studies have shown that prenatal maternal
43
+ stress is associated with increased risk for spontaneous abortion,
44
+ preterm labor, fetal malformations, and asymmetric growth retar-
45
+ dation [1]. Evidence of long-term functional disorders in the
46
+ offspring after prenatal exposure to stress is limited. But retro-
47
+ spective studies [2] and two prospective studies support such ef-
48
+ fects [3] on the behavioral development with attentional deficits,
49
+ hyper anxiety and disturbed social behavior [4].
50
+ Pregnant women respond differently to identical stressful
51
+ stimuli, depending on genetic factors, personality traits, previous
52
+ experience and social support. Anxiety and depression are two
53
+ common responses to stressfully demanding situations that may
54
+ affect healthy progression of pregnancy as observed by many re-
55
+ searchers. Bennett et al. reported Prevalence rates of clinical
56
+ depression at 7.4%, 12.8%, and 12.0% for the first, second, and third
57
+ trimesters, respectively [5]. There are studies that have shown that
58
+ high scores of Anxiety results in increased incidence of preterm
59
+ labor [6], reduced birth weight and small fetal head size [7].
60
+ A review of preclinical and clinical studies on the deleterious effects
61
+ of maternal depression showed that it affects not only the mother
62
+ but also has short and long term effects on the offspring [8].
63
+ Depressed women had higher symptom frequency, more discom-
64
+ fort, flatulence and fatigue [9]. Postpartum weight retention in
65
+ obese mothers was associated with psychological distress during
66
+ early pregnancy [10]. Depression that continues in the Postpartum
67
+ period is associated with negative childbirth experience [11] and
68
+ when untreated, impairs the mother-infant attachments and re-
69
+ sults in cognitive, emotional and behavioral consequences in
70
+ childhood [12]. Ventegodt et al. showed that the global quality of
71
+ life of the mother during pregnancy is important for the quality of
72
+ life of the child and their attitudes toward life and philosophy of life
73
+ [13]. Studies on adolescent quality of life (HR-QOL) point to
74
+ adversity in the neural pathways that are determined in their fetal
75
+ developmental stage [14]. It is alarming to note that review articles
76
+ say that there are no controlled studies on the safety of antide-
77
+ pressant use in pregnancy and lactation [8]. This points to an urgent
78
+ need for non-pharmacological interventions.
79
+ Very simple
80
+ interventions
81
+ such as
82
+ educating
83
+ women
84
+ by
85
+ providing information about benefits and risks of prenatal physical
86
+ activity motivates them to practice better health behaviors [15].
87
+ Cognitive-behavioral intervention led to improvement in the bio-
88
+ logical stress response of pregnant women with sub clinically
89
+ elevated stress, anxiety, or depressive symptoms [16]. A controlled
90
+ clinical trial on outpatient ante-partum women who met DSM-IV

100
+ criteria for major depressive disorder, found significant improve-
101
+ ment in mood after 16 weeks of Interpersonal psychotherapy [17].
102
+ Massage therapy showed reduced anxiety, improved mood and
103
+ better sleep with fewer complications during labor and postnatal
104
+ period [18] with lesser incidence of prematurity and low birth
105
+ weight [19]. Exercise in the third trimester was associated with
106
+ lesser state-anxiety [20]. Applied relaxation training showed sig-
107
+ nificant reductions in state/trait anxiety and perceived stress [21].
108
+ ‘Attending nurse-led relaxation education’ reduced the need for
109
+ cesarean section, and/or instrumental extraction and also the
110
+ number of infants with low birth weight [22].
111
+ Yoga, with its holistic approach, has been used to promote
112
+ positive health for centuries in India [23]. Several clinical trials
113
+ point to the beneficial effects of yoga in Asthma [24,25], Hyper-
114
+ tension [26,27], Pain Managament [28,29], Diabetes [30], Cancer
115
+ [31], and Mood Changes [32]. Yoga improves the Quality of life [33]
116
+ and reduces stress as evidenced by reduced anxiety levels [34,35],
117
+ serum cortisol levels [36,37] with lower metabolic rate in yoga
118
+ practitioners [38].
119
+ To date there are a few publications on the effect of integrated
120
+ approach of yoga (IAYT) on pregnancy outcome [39]. In a case
121
+ control study Narendran et al. showed the positive effects of IAYT
122
+ on mode of delivery, birth weight of the infant and pregnancy
123
+ complications. Again, in those pregnancies with abnormal flow in
124
+ umbilical and uterine arteries (observed in ultrasound Doppler
125
+ scanning), there was improvement in birth weight, decrease in
126
+ preterm labor and intrauterine growth restriction [40].
127
+ Sun et al. [41]. observed that 12e14 week yoga program pro-
128
+ duced lesser scores on Discomforts of Pregnancy (DoPQ) in 38e
129
+ 40th week of gestation with higher self-efficacy and outcome
130
+ expectancy in both the active and second stages of labor. It is
131
+ known that Physiological stress reactivity is dampened during
132
+ pregnancy [42]. We demonstrated improved autonomic adapt-
133
+ ability (in heart rate variability) with reduced perceived stress
134
+ levels [43] that resulted in better quality of life (WHOQoL 100) and
135
+ interpersonal relationships (FIRO-B) after integrated yoga in
136
+ pregnant women [44]. We hypothesized that these observations
137
+ could be due to reduced anxiety and depressive responses to
138
+ perceived stress and planned to document these variables in the
139
+ same cohort in which we observed the above changes which is
140
+ reported here.
141
+ 2. Methods
142
+ 2.1. Participants
143
+ 2.1.1. Sample size
144
+ A sample size of 88 was obtained by using the ‘G power’ soft-
145
+ ware, (alpha ¼ 0.05, power ¼ 0.8 and effect size ¼ 0.54). The effect
146
+ size was calculated from the mean and SD values of an earlier
147
+ interventional study [45]. We recruited 122 women to provide for
148
+ any dropouts.
149
+ Ninety six women (20e35 years) between 18th to 20th weeks
150
+ of gestation who satisfied the selection criteria were randomized
151
+ to yoga (51) and control groups (45). They were recruited from a
152
+ pool of 200 subjects who had registered for antenatal care at
153
+ Maiya multispecialty hospital in south Bengaluru, India. The
154
+ following criteria were followed to ensure inclusion of only
155
+ normal pregnancies and avoid those who may have high stress
156
+ levels: (a) gestational age between 18 and 20 weeks, (b) prime
157
+ gravidae and (c) multi gravidae with at least one live child. The
158
+ exclusion criteria were: (a) associated medical problems, (diabetes,
159
+ hypertension, etc), (b) multiple pregnancy, (c) IVF pregnancy, (d)
160
+ previous history of IUGR, (e) maternal physical abnormalities, (f)
161
+ fetal abnormality on ultrasound scanning and (h) previous expo-
162
+ sure to yoga.
163
+ 2.2. Consent
164
+ Institutional ethical committee of the yoga university (S-VYASA)
165
+ had cleared the project. Signed informed consent was obtained
166
+ from all subjects before randomization.
167
+ 2.3. Design
168
+ This was a prospective randomized two-armed control design
169
+ with supervised practices for both groups from the time of
170
+ recruitment till delivery.
171
+ 2.4. Procedure
172
+ After obtaining the signed informed consent, the subjects were
173
+ allocated to two groups (yoga and control) using a computer
174
+ generated random number (www.Randomizer.com) table. Pre and
175
+ post assessments were done at the time of recruitment (between 18
176
+ and 20 weeks of pregnancy) and at 36th week. Yoga group prac-
177
+ ticed specific set of integrated yoga. The control group practiced
178
+ standard antenatal exercises. Both groups learnt the practices (in
179
+ batches of 4e10) from trained instructors in sessions of 2 h/day (3
180
+ days/week) for one month. Subsequently, they continued the
181
+ practices at home using a pre recorded instruction cassette for one
182
+ hour each day. Both groups had refresher classes of 2 h each time
183
+ they came for their antenatal obstetric assessment. (Once in 3
184
+ weeks up to 28 weeks and every two weeks up to 36 weeks).
185
+ Compliance was ensured by phone calls and maintenance of an
186
+ activity diary.
187
+ 2.5. Masking
188
+ As this was an interventional study, the participants or the
189
+ trainer could not be blinded. Attempts were made to mask
190
+ wherever feasible to reduce the bias. The team who did the as-
191
+ sessments was not involved in administering the intervention.
192
+ The statistician who did the randomization and analysis was blind
193
+ to the source of the data. Care was taken to avoid interaction and
194
+ exchange of techniques between participants of the two groups by
195
+ staggering the timings and venue of the classes for the two
196
+ groups.
197
+ 2.6. Intervention
198
+ The yoga module used for the experimental intervention called
199
+ Integrated approach of yoga therapy (IAYT) during pregnancy
200
+ which was developed specifically for the purpose culled out from
201
+ original scriptures (Patanjali Yoga Sutras, and Mandukaya Karika)
202
+ that highlight the concepts of a holistic approach to health man-
203
+ agement at physical, mental, emotional and intellectual levels with
204
+ techniques to improve mental equilibrium. Table 1 shows the list of
205
+ yoga practices used in three trimesters. The number of asanas
206
+ (physical postures) performed in standing, sitting or lying prone or
207
+ supine postures went on reducing with increasing gestational age.
208
+ These asanas done with internal awareness (eyes closed) promotes
209
+ full range of motion of the body part by graded gradually increasing
210
+ stretches followed by relaxation, that results in flexibility of the
211
+ joints and strengthening of the muscles. The breathing techniques
212
+ (Pranayama) focus on conscious prolongation of all three compo-
213
+ nents of breathing cycle (inhalation, effortless retention, and
214
+ exhalation) that results in better vital capacity and balance of vital
215
+ energy. Meditation included techniques such as listening to one’s

219
+ own breath or repeating a mantra to bring about a state of self-
220
+ awareness and inner calm [39].
221
+ The control group practiced the standard antenatal practices
222
+ which included simple stretching exercises (Table 1) approved by
223
+ the Executive Council of the society of Obstetrician and Gynecolo-
224
+ gists of Canada, and by the board of directors of the Canadian so-
225
+ ciety for exercise physiology [46].
226
+ 2.7. Assessments
227
+ 1. PEQ: Pregnancy experiences Questionnaire
228
+ The Pregnancy experiences Questionnaire addresses Pregnancy-
229
+ specific stressors and concerns experienced during pregnancy [47]
230
+ PEQ has 41 questions related to somatic symptoms, Pregnancy,
231
+ fetus/infant and parenting concerns, baby-image, and attitudes to
232
+ sex. Women are asked to rate how severe each item has been for
233
+ them in the past month on a three-point scale (1e3) with the total
234
+ scores ranging from 41 to 123 with higher scores indicating higher
235
+ stress levels. PEQ has good internal consistency (a ¼ 0.87e0.91)
236
+ [48] with Test-retest reliability coefficients varying from 0.64e0.84
237
+ depending on the time period sampled (one to six months).
238
+ 2. STAI: state trait anxiety inventory
239
+ The STAI [49] comprises two-self report scales for measuring
240
+ two distinct anxiety concepts, the State anxiety and Trait anxi-
241
+ ety. Both scales contain 20 statements that asks the respondent
242
+ to describe how she feels at a particular moment (state anxiety)
243
+ or how she generally feels (trait anxiety). State anxiety is
244
+ conceptualized as a transitory emotional state, where as trait
245
+ anxiety refers to relatively stable individual differences in
246
+ proneness to anxiety. The respondents were required to rate
247
+ themselves on a four point Lickhert scale ‘not at all’ to ‘very much
248
+ so’ on various anxiety related symptoms which they experience
249
+ in the past weeks for the state scale or how they generally feel

+ for the trait scale [49]. STAI is widely used and has been shown to
454
+ have high reliability and validity [49] with a Cronbach’s alpha of
455
+ 0.88 and 0.83 for state (STAI-I) and trait anxiety (STAI-II) respec-
456
+ tively [50].
457
+ 3. HADS: Hospital Anxiety Depression Scale
458
+ HADS is a self-assessment scale developed by Zigmond and
459
+ Snaith [51]. It is a widely used self-report instrument designed to
460
+ assess the dimensions of anxiety and depression in non-psychiatric
461
+ population [52,53]. It has 14 items that consist of two subscales of
462
+ seven items each, to measure the levels of anxiety and depression.
463
+ Each item is rated on a scale from 0 (not at all) to 3 (very much).
464
+ This is a widely used reliable scale with Cronbach’s alpha of 0.89
465
+ [54].
466
+ 3. Data analysis
467
+ Statistical analysis was done using SPSS Version 10.0. Chi
468
+ squared test and independent samples ‘t’ test were used for base-
469
+ line comparisons and mean differences within groups. As the data
470
+ were not normally distributed, ManneWhitney test (between
471
+ groups) and Wilcoxon’s test (within groups) were used for statis-
472
+ tical analysis.
473
+ 4. Results
474
+ Fig. 1 shows the trial profile. 200 women who registered at the
475
+ antenatal clinic of the institute were screened; 122 women who
476
+ satisfied the selection criteria, 105 consented and the final data was
477
+ available on 96 women (yoga 51 and control 45). There were 2 drop
478
+ outs in yoga and 7 in control. The reasons for drop out included: (i)
479
+ Irregular attendance (ii) shifts from control to yoga group because
480
+ of increasing popularity of yoga through the media, and (iii) social
481
+ reasons: moved out of Bangalore for delivery and post partum care
482
+ to mother’s house as a sentimental social custom of south India.
483
+ The two groups were matched on maternal characteristics
484
+ (Table 2) and baseline scores were not normally distributed.
485
+ Table 3 shows the results after the intervention. State (STAI I)
486
+ anxiety reduced in yoga (15.65%, p < 0.001) with significant dif-
487
+ ference between groups (P < 0.001); it increased in the control
488
+ group (13.76 %, p < 0.007); Trait (STAI II) anxiety also reduced in
489
+ yoga (8.97%, p < 0.001) and increased in the control group (5.02%,
490
+ p < 0.09) with significant difference between groups (p < 0.001).
491
+ Anxiety as measured by HADS also reduced in yoga (29.12%,
492
+ p < 0.001) with significant difference between groups (p < 0.001).
493
+ Depression (HADS) reduced in yoga (30.67%, p < 0.001) with sig-
494
+ nificant difference between groups (p < 0.001). Pregnancy related
495
+ experience questionnaire showed significant changes in the yoga
496
+ (26.86%, p < 0.001) group with significant difference between
497
+ groups (p < 0.001).
498
+ 5. Discussion
499
+ This prospective randomized control study compared the effect
500
+ of daily practice of integrated yoga program with standard ante-
501
+ natal exercises in normal pregnant women from 20th to 36th
502
+ weeks. Anxiety and Depression reduced with improvement in
503
+ pregnancy experience after yoga with significant difference be-
504
+ tween groups (P < 0.001). There were no adverse effects in any of
505
+ the cases.
506
+ Although the women in control group were doing the practices
507
+ of physical activity as planned and were reporting the regularity of
508
+ practices, there was significant increase in state (13.76%) and trait
509
+ (5%) anxiety as pregnancy advanced. The reason for this increase
510
+ could be: although it is well known that physical activity reduces

515
+ stress and improves health, it appears that, this may not be suffi-
516
+ cient to prepare the woman to manage the psychological response
517
+ (anxiety) to demanding situations of life, i.e. anticipation of com-
518
+ plications and pain of delivery. Yoga, by definition is mastery over
519
+ the modifications of mind (Patanjali e chitta vrtti nirodhah) and
520
+ offers techniques that invoke the inbuilt capability to manage the
521
+ psychological and physiological challenges. Regular practice of in-
522
+ tegrated yoga leads to a balanced state of mind (samatvam yoga as
523
+ stated in bhagavadgita) that does not get perturbed by these
524
+ challenges [55] by improving neural plasticity [56].
525
+ 5.1. Comparisons
526
+ There are very few studies that have looked at the effect of yoga
527
+ on stress, anxiety or depression during pregnancy. Two studies
528
+ have reported reduction in trait anxiety (p < 0.05) in third trimester
529
+ in
530
+ healthy
531
+ pregnant
532
+ nulliparous
533
+ women
534
+ who
535
+ practiced
536
+ mindfulness-based yoga between 12 to 32 weeks [57,58]. We have
537
+ earlier reported reduction in perceived stress and better autonomic
538
+ adaptability [43]. There are several studies that have looked at the
539
+ effect of different types of yoga practices on anxiety, depression,
540
+ wellness and quality of life in clinical conditions and normal
541
+ healthy volunteers. To our knowledge this is the first study that has
542
+ reported the effect of yoga on pregnancy experience, anxiety and
543
+ depression.
544
+ Nidhi et al. reported significant reductions in both state [12.27%]
545
+ and trait [14.97%] anxiety in adolescent girls with polycystic
546
+ ovarian disease [59]. Subramanya et al. [60] observed a reduction in
547
+ state anxiety (22.4%) immediately after Cyclic Meditation in normal
548
+ volunteers. Rao et al. in their randomized control study on early
549
+ breast cancer patients observed reduction in both state and trait
550
+ anxiety by add-on yoga [61]. Twelve weeks of Iyengar yoga reduced
551
+ the state and trait anxieties in normal volunteers [62] and in
552
+ women with mental distress [63]. Our present study observed
553
+ a15.65% reduction in state anxiety and 9% reduction in trait anxiety
554
+ in yoga group of pregnant women.
555
+ There was a 48.2% reduction in anxiety levels (HADS) after 6
556
+ weeks of add-on yoga in breast cancer patients undergoing radia-
557
+ tion therapy [64]. Sudarshan Kriya and related practices reduced
558
+ the scores on depression from 4.11  2.99 to 2.73  2.19 and Anxiety
559
+ scores from 7.60  3.71 to 5.87  3.18 after yoga practice in adult
560
+ volunteers [65]. In the present study, there was better reduction in
561
+ anxiety score (HADS) in the yoga (29.12%) group compared to the
562
+ control group (1.69%); reduction in Depression score was also
563
+ higher in yoga (30.67%) than the control group (3.57%).
564
+ Looking at effect of yoga on the discomforts of pregnancy, we
565
+ observed higher degree of improvement in the yoga (26.86%) group
566
+ as compared to control group (13.55%) in their Pregnancy experi-
567
+ ence .Sun et al. [41]. studied the effects of a 12e14 week yoga
568
+ program and showed significantly less discomfort in the 38e40th
569
+ week
570
+ of
571
+ gestation with
572
+ higher
573
+ self-efficacy expectancy and
574
+ outcome expectancy in both the active and second stages of labour
575
+ than the women in the control group.
576
+ 5.2. Mechanism: stress reduction
577
+ Anxiety and depression are the experiences that a person
578
+ actually feels in response to perceived stress. Studies using ultra-
579
+ sound Doppler flow velocimetry have shown high resistance of the
580
+ uterine arteries in women with high anxiety scores in the third
581
+ trimester [66]. It has been reported that high scores on perceived
582
+ stress and anxiety are related to increase in HPA-Axis-activity [67].
583
+ Based on our results we may hypothesize that yoga’s benefits

782
+ would be mediated through reduction in the abnormal activity of
783
+ the maternal sympatheticeadrenalemedullary system (SAM) and
784
+ hypothalamicepituitaryeadrenocortical axis (HPA-axis) [42]. Bet-
785
+ ter autonomic stability with reduced sympathetic arousal and
786
+ increased parasympathetic tone has been demonstrated in normal
787
+ adults [68] after yoga. Also, we have shown reduced perceived
788
+ stress and better autonomic adaptability during normal pregnancy
789
+ after integrated yoga [43] pointing to better plasticity of ANS and its
790
+ ability to restore the basal state of relaxation quickly after a stress
791
+ response.
792
+ Better psychological health resulting from stress reduction may
793
+ have contributed to the improvement observed on PEQ in this
794
+ study. We have published earlier that these women had much
795
+ better quality of life and interpersonal relationships [44] that points
796
+ to the positive psychological state that yoga can induce. Thus, these
797
+ psychological changes may explain the physiological changes
798
+ observed as better outcomes seen in our earlier studies on inte-
799
+ grated yoga in both normal [39,43] and high risk pregnancies
800
+ [44,69]. This may also promote a healthier ANS programming in the
801
+ fetus [42,70] which may help in preventing diseases related to
802
+ autonomic nervous system hyperactivity in the offspring.
803
+ The Word yoga comes from a Sanskrit root ‘Yuj’ that means ‘to
804
+ yoke’, ‘to join’, to unite the mind, body and the spirit; and to direct
805
+ and concentrate one’s attention by calming down the restless mind
806
+ [55]. Thus the deep physiological rest that is achieved by the
807
+ components of pranayama, meditation and other mindfulness
808
+ practices incorporated in the integrated yoga program could be the
809
+ major aspects that could explain the observed benefits.
810
+ 6. Conclusion
811
+ Regular practice of integrated yoga in second and third trimester
812
+ is more effective than antenatal exercises in reducing anxiety,
813
+ Depression and improving the pregnancy experience.
814
+ 6.1. Limitations
815
+ a. Possible interaction between the groups could not be avoided.
816
+ b. Requests for shift from control to yoga group due to popularity
817
+ of yoga through the media led to unexpected number of drop
818
+ outs.
819
+ 6.2. Generalizability
820
+ As yoga is widely accepted even in the west today and there are
821
+ good number of centers round the globe which have been teaching
822
+ yoga for pregnancy, this study offers the scientific evidence for the
823
+ safety and benefits of this module of integrated yoga. Thus, we
824
+ recommend that obstetricians incorporate these practices in all
825
+ antenatal clinics in all sections of the society.
826
+ 6.3. Suggestions for future research
827
+ More studies in different ethnic groups, in abnormal preg-
828
+ nancies and by use of different types of Yoga may throw more
829
+ light on ANS modulations in pregnancy. Multi centric trials
830
+ including a more comprehensive battery of variables to measure
831
+ ANS functions and changes in hormonal levels may unravel the
832
+ hidden mechanisms of yoga, since the exact nature of the auto-
833
+ nomic changes involved in stress adaptation are poorly under-
834
+ stood [70].
835
+ Conflict of interest
836
+ We hereby declare that authors do not have any conflict of in-
837
+ terest while carrying out this research.
838
+ Source of funding
839

+ Naturopathic Fasting Therapy is the cornerstone of most Naturopathic therapy protocols. It has been claimed to
2
+ reduce the acidity of the body, but this has not been conclusively proven. The present study was designed to assess
3
+ the effect of Naturopathic Fasting Therapy on Urine pH young healthy volunteers. Seventy participants with ages
4
+ ranging from 19-21 years (group mean age ±SD; 20 ±0.8 years) were assigned to either a fasting group (n=35) or a
5
+ vegetarian diet group (n=35). The two groups were matched for age, education and routines. Fasting was conducted
6
+ for a period of five days under supervision by project coordinators. We executed a matched controlled design with
7
+ urine pH assessed by testing first void midstream urine using pH meter at baseline and every day subsequently until
8
+ the period of fasting ended. Data were analyzed using IBM SPSS 20. The data were checked for normality. The data
9
+ was checked for normality and then a Paired samples t-test was performed to investigate statistically significant
10
+ difference within-group in urine pH of fasting group and control group. Urine pH increased by 0.24 ±0.49 pH units
11
+ (p <0.05) after five days'Naturopathic Fasting Therapy Naturopathic Fasting Therapy significantly increases Urine
12
+ pH. This signifies that acidity of the plasma is reduced, which can be linked to many health benefits.

+ Discussion
289
+ In the present study, we investigated whether Naturopathic Fasting
290
+ Therapy is associated with any change in urine pH. We found that the
291
+ fasting group demonstrated higher urine pH against those eating a
292
+ normal vegetarian diet for 5 days.

+ An acidic Urine and ECF are associated with negative outcomes
294
+ in a number of diseases, such as bladder cancer, solid tumors and
295
+ high systolic blood pressure.[12, 13, 14] One of the most important
296
+ indicators of Urine pH is diet. Diet-derived acid causes a shift in pH
297
+ towards an acidic one, and higher fruit and vegetable intake as well
298
+ as lower meat are associated with a more alkaline urine pH.[10]

+ acidity of, and increasing the pH of the urine and the blood. On the
348
+ other hand, there is one factor that would indicate a shift in urine pH
349
+ towards acidity. During prolonged periods of starvation, there is an
350
+ shift from glycolysis to lipolysis and other metabolic adaptations to
351
+ low calorie intake, causing a shift in blood pH towards an acidic one.
352
+ However, there are juices provided during NF Therapy that might
353
+ prevent this from occurring, by providing a source of energy from
354
+ simple sugars such as those present in fruits and honey.[19] In order
355
+ to understand the overall effect of this complex mechanism of acid-
356
+ base balance, we looked at urine pH readings during the first eight
357
+ days of the study, till the last day of NF Therapy.
358
+ First Void Urine pH increased by 0.24 ±0.49 pH units, (p<0.05),
359
+ showing a trend towards alkalinity, in conformation with the PRAL
360
+ of -2.28 mEq/day of the diet provided to the Naturopathic Fasting
361
+ Therapy group. Net Acid Excretion, thus, reduced during an
362
+ intervention of NF Therapy, showing that the acidosis associated
363
+ with a shift in metabolism to lipolysis and protein utilisation is
364
+ countered effectively and overcome by Naturopathic Fasting
365
+ Therapy.
366
+ These findings suggest that a five-day Naturopathic Fasting
367
+ Therapy regimen can lead to a reduction in acidity of the ECF in
368
+ healthy individuals. Thus, fasting can have important uses in the
369
+ background of modern day diets, in which net acid load is
370
+ considerably high compared to hunter-gatherer civilizations[4], due
371
+ to higher sodium:potassium and chloride:bicarbonate consumption
372
+ ratio,[6] reduced magnesium, potassium and fiber, and increased fat
373
+ and simple sugars.[5] Also, fasting may be a potentially effective tool
374
+ to use in geriatric care, as renal acid-base regulatory function reduces
375
+ with age, resulting in an increased diet-induced metabolic
376
+ acidosis.[8]
377
+ Further studies are warranted in all age groups and conditions to
378
+ ascertain this effect of Naturopathic Fasting Therapy.

+ Abstract:
15
+ Background: Mud pack is one of the fundamental therapeutic procedures used in naturopathy to treat various
16
+ diseases. There is a lack of scientific evidence for the use of mud-pack application in psychological variables. The
17
+ present study aims at evaluating the effect of mud pack to eyes on psychological variables in healthy volunteers.
18
+ Materials and methods: Sixty healthy individuals with the age varied from 18 to 21 years were recruited and
19
+ randomly divided into either mud-pack group (n=30) or wet-pack group (n=30). Mud-pack group received
20
+ mud pack to eyes and wet-pack group received wet pack to eyes for a duration of 30 min/session (a total of 15
21
+ sessions). Psychological assessments like Mindful Attention Awareness Scale (MAAS), Perservative Thinking
22
+ Questionnaire (PTQ) and Positive and Negative Affect Scale (PANAS) were taken before and after the interven-
23
+ tion. Statistical analysis was performed using statistical package for the social sciences, version 16.
24
+ Results: Result of this study showed a significant reduction in PTQ score and PANAS negative score in both
25
+ mud-pack and wet-pack groups. But, a significant increase in MAAS score was observed only in the mud-pack
26
+ group, unlike wet-pack group. However, there was no significant difference found in between group analysis.
27
+ Conclusions: Result suggests that though both mud pack and wet pack to eyes reduced the scores of PTQ and
28
+ negative affects, only mud pack to eyes increased the state of mindfulness in healthy individuals.

32
+ Background
33
+ Mud is a mixture of inorganic and organic matter with water, which has undergone geological and biological
34
+ processes under the influence of various physico-chemical factors [1]. Mud-pack therapy is a therapeutic ap-
35
+ plication of natural products containing a mix of mineral or mineral-medicinal water (including seawater or
36
+ salt water from lakes) with organic or inorganic compounds resulting from geological, biological or evens both
37
+ processes, used in the form of a wrap or a bath [2].
38
+ In India, mud pack to eyes is one of the treatment procedures commonly employed by the naturopathy
39
+ physicians in patient with psychological and psychosomatic disorders. In previous studies, mud therapy was
40
+ shown to be an effective treatment modality in various psychosomatic diseases like rheumatoid arthritis [3],
41
+ psoriatic arthritis [4], fibromyalgia syndrome [5], spondylitis associated with inflammatory bowel disease [6]
42
+ and also in osteoarthritis of knee [7]. Though mud therapy is used in various psychological and psychosomatic
43
+ diseases, there is lack of evidence in its precised psychological effects. To the best of our knowledge, there is no
44
+ known study reported the effect of mud pack to eyes on psychological variables. Hence, this present study was
45
+ performed to evaluate the effect of mud pack to eyes on psychological variables in healthy volunteers.

55
+ Materials and methods
56
+ Subjects
57
+ Sixty healthy individuals with the age varied from 18 to 21 years were recruited from a residential college
58
+ (located in South India, India.). Both male and female genders aged 18 years and above who were willing to
59
+ participate in the study were included. Subjects with the history of any systemic and mental illness, regular use
60
+ of medication for any diseases, addiction to smoking and alcoholism were excluded from the study. The study
61
+ protocol was approved and a written informed consent was obtained from each subject.
62
+ Study design
63
+ This is a pilot randomized controlled trial, in which subjects were randomly divided into either mud-pack group
64
+ (n=30) or wet-pack group (n=30). Mud-pack group received mud pack to eyes and wet-pack group received
65
+ wet pack to eyes. Baseline and post-test assessments were taken before and after the intervention. Trail profile
66
+ has been given in Figure 1.

68
+ Randomization
69
+ All the recruited subjects were randomly divided into either mud-pack group (n=30) or wet-pack group (n=30)
70
+ using computerized randomization. Randomization was performed by one of the authors who did not involve
71
+ in either intervention or any part of the investigation.

78
+ Blinding/masking
79
+ Since the intervention was given with the closed eyes, all the subjects were blinded to the mud-pack and wet-
80
+ pack interventions. Investigator was kept blind to the mud-pack and wet-pack groups.
81
+ Assessment
82
+ Mindful Attention Awareness Scale (MAAS): It is a 15-item single-dimension measure of trait mindfulness
83
+ designed to assess a core characteristic of mindfulness, namely, a receptive state of mind in which attention,
84
+ informed by a sensitive awareness of what is occurring in the present, simply observes what is taking place.
85
+ Here, the subject was asked to indicate how frequently or infrequently they currently have each experience and
86
+ answer according to what really reflects their experience rather than what they think as their experience should
87
+ be. Response options ranged from 1 to 6, where 1=almost always; 2=very frequently; 3=somewhat frequently;
88
+ 4=somewhat infrequently; 5=very infrequently; 6=almost never. Internal consistency levels (Cronbach’s alphas)
89
+ generally range from 0.80 to 0.90. The MAAS has demonstrated high test–retest reliability, discriminant and
90
+ convergent validity, known-groups validity and criterion validity [8].
91
+ Perseverative Thinking Questionnaire (PTQ): It is a 15-item questionnaire in which the subjects were asked to
92
+ describe how he/she typically thinks about his/her negative experiences or problems. They were instructed to
93
+ read and rate all the 15-item the extent to which they apply to them when they think about negative experiences
94
+ or problems. Response options ranged from 0 to 4, where 0=never; 1=rarely; 2=sometimes; 3=often; 4=almost
95
+ always. Internal consistencies (Cronbach’s alphas) were found for the total scale is 0.95 [9].
96
+ Positive and Negative Affect Schedule (PANAS): It consists of two ten-item scales that describe different
97
+ feelings and emotions for positive affects (PAs) and negative affects (NAs) respectively. The ten items for PA
98
+ are attentive, interested, alert, excited, enthusiastic, inspired, proud, determined, strong and active, and the
99
+ ten items for NA are distressed, upset, hostile, irritable, scared, afraid, ashamed, guilty, nervous and jittery.
100
+ Subjects were instructed to read each item and then mark the appropriate answer in the space next to that word
101
+ to indicate to what extent they have felt like this in the past few hours. Response options ranged from 1 to 5,
102
+ where 1=very slightly or not at all; 2=a little; 3=moderately; 4=quite a bit; 5=extremely. The scores generated
103
+ used to vary along the scale of 10–50, with lower scores indicating low (positive or negative) affect and higher
104
+ scores indicating high (positive or negative) affect. The validity and the reliability of the PANAS have been
105
+ tested [10].
106
+ Intervention
107
+ Mud-pack group: All the subjects received mud pack to eyes. Mud pack was prepared using clay obtained from
108
+ about 6 ft below the surface of the earth. Clay was exposed in sunlight, crushed very well, and pebbles and
109
+ stones were removed. The clay was then made into a smooth paste with pure water 1 h before the intervention.
110
+ Mud was kept on a strip of cotton cloth to prepare eye pack (9 cm × 6 cm × 1 cm). The mud pack was prepared
111
+ using water at 20–21oC. All the subjects were asked to lay down on the back with closed eyes, followed by mud
112
+ pack was kept on the subject’s closed eyelids for the duration of 30 min/session for 15 sessions.
113
+ Wet-pack group: All the subjects received wet pack to eyes. Wet pack (9 cm × 6 cm × 1 cm) was prepared
114
+ using cotton cloth wetted in water at the temperature of 20–21oC. All the subjects were asked to lay down on
115
+ the back with closed eyes, followed by mud pack was kept on the subject’s closed eyelids for the duration of 30
116
+ min/session for 15 sessions.
117
+ Statistical analysis
118
+ All the data were checked for the normality test using Kolmogorov–Smirnov and Shapiro–Wilk. Statistical
119
+ analysis was performed using paired sample t-test for within group and independent sample t-test for between
120
+ groups analysis. p-Value <0.05 was considered as significant.
121
+ Results
122
+ Of 83 subjects, 23 subjects did not fulfil the criteria and hence did not include in the study. Recruited 60 sub-
123
+ jects were randomized into either mud-pack group (n=30) or wet-pack group (n=30). Five subjects in each

229
+ Result of this study showed a significant reduction in PTQ and PANAS negative scores in both mud-pack
230
+ and wet-pack groups. But, a significant increase in MAAS score was observed only in mud-pack group unlike
231
+ wet-pack group. However, there was no significant difference found in between groups (Table 2).
232
+ Discussion
233
+ Result of this study showed a significant reduction in PTQ score and PANAS NA score along with a significant
234
+ increase in MAAS score in subjects those who underwent mud pack to eyes. It suggests that mud pack to eyes
235
+ is an effective modality in reducing the repeated negative thinking (RNT) and NAs while increasing the state
236
+ of mindfulness in healthy individuals.
237
+ A number of different emotional problems have been found to be related to heightened levels of repetitive
238
+ negative thinking in the form of worry and/or rumination. For example, individuals with depressive disor-
239
+ ders have shown to ruminate excessively about the symptoms, causes and consequences of the depression. The
240
+ heightened levels of rumination and/or worry are present in various disorders including post-traumatic stress
241
+ disorder, social phobia, obsessive–compulsive disorder, insomnia, eating disorders, panic disorder, hypochon-
242
+ driasis, alcohol use disorder, psychosis and bipolar disorder. The PTQ is regarded as a valid measure of RNT
243
+ [9]. Result of this study showed a significant reduction in the PTQ score followed by the 15 sessions of mud pack
244
+ to eyes in healthy individuals. It suggests that mud pack to eyes might be useful in reducing RNT. However,
245
+ since this study is conducted in healthy individuals, further studies in clinical population are required to find
246
+ its effect in the prevention and management of various psychological disorders related with RNT.
247
+ In PANAS, the PA represents the extent to which an individual experiences pleasurable engagement while
248
+ the NA represents the extent to which an individual experiences unpleasurable engagement with the envi-
249
+ ronment [10]. The high NA scores reflect ‘subjective distress’ and low NA scores reflect ‘a state of calmness

256
+ and serenity’ [11]. Hence, in this study, a significant reduction in NA score after 15 sessions of mud pack to
257
+ eyes suggests that mud-pack therapy might be useful in increasing a state of calmness and serenity in healthy
258
+ individuals.
259
+ Mindfulness is defined as paying attention in a particular way: on purpose, in the present moment, and
260
+ non-judgmentally. The MAAS positively correlated with various measures of well-being like life satisfaction,
261
+ optimism, and self-esteem and negatively correlated with neuroticism [8] (a stable temperament that is one of
262
+ the vulnerable factors for depression) [12], depression, anxiety and unpleasant affect [8]. Hence, increase in the
263
+ MAAS score followed by the 15 sessions of mud pack to eyes might be useful in increasing attention, optimism
264
+ and self-esteem in healthy individuals.
265
+ Likewise, wet pack to eyes has also showed a significant reduction in PTQ and PANAS NA scores. However,
266
+ there was no significant change in MAAS score compared to its respective baseline. It suggests that though wet
267
+ pack to eyes is effective in reducing RNT and NAs, it was not effective in increasing the state of mindfulness in
268
+ healthy individuals. Hence, even though both mud pack to eyes and wet pack to eyes are effective in reducing
269
+ RNT and NAs, mud pack to eyes was effective in increasing the state of mindfulness too in healthy individuals.
270
+ In various studies, cold application has shown to be effective in improving cardiovascular functions includ-
271
+ ing workload of the heart [13, 14] and autonomic functions towards either sympathetic withdrawal or parasym-
272
+ pathetic activation [15]. Reduction in sympathetic withdrawal is known to activate a state of relaxation and
273
+ activate relaxation response [16]. And thus, a significant reduction in RNT and NA both in mud-pack group
274
+ and wet-pack group might be possibly through either sympathetic withdrawal or parasympathetic activation
275
+ due to the cooling and relaxing effect followed by the application of wet pack to eyes or mud pack to eyes.
276
+ Though water application produces effect that are similar to mud application and can be applied more easily
277
+ and cleanly than mud application, the moisture and coolness retaining property of a mud application (mud
278
+ pack or direct application) is much longer than a water application (pack or compress) [17]. It suggests that
279
+ mud pack to eyes might have produced a better relaxation through its longer cooling effect that is needed to
280
+ increase the state of mindfulness than wet pack to eyes.
281
+ Stress is one of the risk factors associated with sympathetic activation that increases muscle rigidity, blood
282
+ pressure, cortisol and restless mood [16] that are known to affect the mindfulness. Whereas, mud application
283
+ has shown to be effective in reducing muscle rigidity [17], blood pressure and salivary cortisol (indicative of
284
+ reduction in stress) and in improving mood [18] that helps in increasing mindfulness. Since mud is a mixture
285
+ of inorganic and organic matter with water, which has undergone geological and biological processes under
286
+ the influence of various physico-chemical factors [1], the beneficial effects of or mechanism of action of mud
287
+ application were reported to be as a result of combination of its chemical and thermal effects [19]. Whereas,
288
+ the beneficial effect of water application is believed to be mainly as a result of thermal effects. Hence, mud
289
+ application has reported to produce a better therapeutic effect than water application [17]. This explains the
290
+ possible mechanism for the increase in the state of mindfulness in mud-pack group unlike wet-pack group.
291
+ However, further studies are required to warrant the effect of mud therapy on autonomic functions and the
292
+ mechanism behind its effect.
293
+ Strengths of the study: To the best of our knowledge, this is the first study reporting the effect of mud pack
294
+ to eyes on various psychological variables in healthy individuals. Subjects and the investigator were blind to
295
+ the mud-pack and wet-pack groups. Both the applications were feasible, acceptable and none of the subject
296
+ reported any adverse reaction throughout the study period. Hence, this study reports a simple, low-cost inter-
297
+ vention that can be given by anyone.
298
+ Limitations of the study: Sample size was small and it was not calculated based on the previous study. Study
299
+ was conducted in healthy volunteers and thus, application of its results in the pathological condition is limiting
300
+ the scope of the study. Assessments were based on the subjective methods and not on any objective measures.
301
+ Hence, further study is required with larger sample size and objective variables in healthy as well as in clinical
302
+ conditions for the better understanding.
303
+ Conclusions
304
+ Result suggests that though both mud pack and wet pack to eyes reduced the scores of PTQ and NAs, only
305
+ mud pack to eyes increased the state of mindfulness in healthy individuals.

39
+ Background and Objective: Attention and memory are essential aspects of cognitive
40
+ health. Yogasanas, pranayama, and meditation have shown to improve cognitive
41
+ functions. There has been no assessment of Trataka (yogic visual concentration) on
42
+ working or on spatial memory. The present study was planned to assess the immediate
43
+ effects of Trataka and of eye exercise sessions on the Corsi-block tapping task (CBTT).
44
+ Methods: A total of 41 healthy volunteers of both genders with age 23.21 ± 2.81 years
45
+ were recruited. All participants underwent baseline assessment, followed by 2 weeks of
46
+ training in Trataka (including eye exercise). Each training session lasted for 20 min/day
47
+ for 6 days a week. After completion of the training period, a 1-week washout period
48
+ was given. Each participant then was assessed in two sessions in Trataka and in eye
49
+ exercise on two separate days, maintaining the same time of the day. Repeated measure
50
+ analysis of variance with Holm’s adjustment was performed to check the difference
51
+ between the sessions.
52
+ Results: Significant within-subjects effects were observed for forward Corsi span
53
+ andforward total score (p < 0.001), and also for backward Corsi span (p < 0.05) and
54
+ backward total score (p < 0.05). Post hoc analyses revealed Trataka session to be better
55
+ than eye exercises and baseline. The eye exercise session did not show any significant
56
+ changes in the CBTT.
57
+ Conclusion: The result suggests that Trataka session improves working memory,
58
+ spatial memory, and spatial attention.

+ INTRODUCTION
61
+ Yoga, an ancient Indian tradition, is aimed at all-round personality development (Taimni, 2010).
62
+ The practices in the discipline of yoga include yama and niyama (moral and ethical conduct),
63
+ asana (physical postures), pranayama (regulated breathing), dharana, dhyana (meditation), and
64
+ shuddhikriya (cleansing practices). Scientific research in recent times has explored the positive
65
+ impact of yoga practices on various domains of physiology and psychology in healthy and
66
+ therapeutic settings (Field, 2016). One major area of interest in yoga research has been the effects of
67
+ yoga practices on cognition and performance. Yoga practices appear to prevent neurodegeneration
68
+ and enhance neuroplasticity by influencing specific brain areas involved with domains of cognition

+ Trataka and Cognition
74
+ such as hippocampus, amygdala, prefrontal cortex, insula, and
75
+ default mode network (Marciniak et al., 2014; Gothe et al.,
76
+ 2019). A meta-analysis, which included fifteen RCTs and
77
+ eight acute exposure studies, indicated the beneficial effect of
78
+ yoga on cognition, attention, processing speed, and memory
79
+ (Gothe and McAuley, 2015).
80
+ Various aspects of cognition, such as spatial and visual
81
+ memory scores (Joshi and Telles, 2008; Garg et al., 2016; Gupta
82
+ et al., 2019), verbal memory (Naveen et al., 1997), executive
83
+ functions, attention, and concentration (Chattha et al., 2008),
84
+ working memory (Subramanya and Telles, 2009), response
85
+ inhibition (Rajesh et al., 2014), visual attention (Jarraya et al.,
86
+ 2019), and task-switching (Anusuya et al., 2021), were found to be
87
+ positively influenced through yoga practices such as yogasanas,
88
+ pranayama, and meditation techniques. Yoga practice was found
89
+ to be better than physical exercises in improving cognitive
90
+ functions in school children (Vhavle et al., 2019).
91
+ The classical texts of Hathayoga described the profound
92
+ impact of the six cleansing techniques on various aspects of
93
+ one’s personality, which are also validated through empirical
94
+ studies (Muktibodhananda, 1999; Swathi et al., 2020). Trataka
95
+ (Yogic Visual concentration) is one of the cleansing techniques
96
+ considered to enhance vision and positively influence cognitive
97
+ processes. Since the process of Trataka involves focused attention
98
+ on a candle flame, the practice leads to the mind becoming
99
+ one-pointed and arouses inner vision (Muktibodhananda, 1999).
100
+ Earlier studies on Trataka and cognition have demonstrated
101
+ enhanced performance in Stroop Task (Raghavendra and Singh,
102
+ 2016; Sherlee and David, 2020), Six Letter Cancelation, Trail
103
+ Making tasks (Talwadkar et al., 2014), and Critical Flicker Fusion
104
+ (Mallick and Kulkarni, 2010). Considering the earlier studies
105
+ on Trataka and cognition, we hypothesize that Trataka may
106
+ positively influence the domains of cognition, such as spatial
107
+ and working memory. Corsi-block tapping task (CBTT) is a
108
+ neuropsychological test that measures visuospatial short-term
109
+ and working memory. The task can be performed using a
110
+ computer to collect the data with precision (Kessels et al.,
111
+ 2000; Siddi et al., 2020). Considering the wide use and ease
112
+ of administration of CBTT, the current study was designed to
113
+ evaluate the effect of Trataka on the performance in the CBTT.
114
+ MATERIALS AND METHODS
115
+ Participants
116
+ A total of 90 volunteers from a University in South India were
117
+ briefed about the study protocol. Out of which, 60 consented to
118
+ participate in the study. The inclusion criteria were normal vision
119
+ (6/6) on Snellen’s chart and regular physical and psychological
120
+ health as assessed by a physician who, otherwise, had no role
121
+ in the study. We included participants with prior experience of
122
+ yoga practices other than Trataka. We excluded volunteers who
123
+ had any known eye disorders, including refractive errors, color
124
+ blindness, glaucoma, cataract, any ophthalmological surgeries, or
125
+ presence of cognitive or neurological disorders, respiratory or
126
+ cardiac, and sensory abnormalities. We also excluded participants
127
+ who had a history of smoking or alcoholism. Finally, 41
128
+ subjects (8 male and 33 female) with their mean (± SD) age
129
+ 23.21 ± 2.81 years were recruited to the study. Out of the 41
130
+ subjects, 31 were pursuing their undergraduate education, 4 were
131
+ graduates, and 6 had completed postgraduation. Their experience
132
+ in yoga ranged between 1 and 7 years (mean ± SD = 3.98 ± 1.44).
133
+ Sample Size Calculation
134
+ The sample size was calculated using G∗power where alpha was
135
+ 0.05 and power was 0.8. The effect size was found to be 0.50
136
+ (Gupta et al., 2019). The recommended sample size resulted in
137
+ being 33 participants for each session. Considering dropouts to
138
+ be at about 25% during the training, we decided to have 41
139
+ participants for each session.
140
+ Ethical Consideration and Trial
141
+ Registration
142
+ The Institutional Ethics committee approved the study of the
143
+ university (Ref. No: RES/IEC-SVYASA/182-C/2021). Written
144
+ informed consent was obtained from individual participants
145
+ before their recruitment to the study. The study was registered
146
+ with the Clinical Trial Registry of India (CTRI/2021/03/031872).
147
+ Trial Design
148
+ We executed a within-subject repeated measures design. All
149
+ participants underwent baseline assessment, followed by 2 weeks
150
+ of training in Trataka (including eye exercise). Each training
151
+ session lasted for 20 min/day for 6 days a week. This orientation
152
+ was administered to avoid individual variations in the practice.
153
+ After completion of the training period, a 1-week washout period
154
+ was given. Each participant then was assessed in two sessions in
155
+ Trataka and in eye exercise on two separate days, maintaining
156
+ the same time of the day (between 4 pm and 6 pm). The order
157
+ of allotment of Trataka and eye exercise sessions was block
158
+ randomized using a web-based random number generator1. Half
159
+ the participants practiced Trataka on day 1, eye exercise on day 2
160
+ and vice versa. The CBTT was recorded following both the trial
161
+ conditions (Trataka and eye exercise).
162
+ Intervention
163
+ Baseline
164
+ The participants were asked to give their baseline assessment
165
+ without any intervention. On the day of baseline assessment, the
166
+ participants were seated comfortably in a cross-legged position
167
+ for 5 min prior to the commencement of the CBTT performance.
168
+ Trataka Session
169
+ Each Trataka session consisted of 20 min practice. Throughout
170
+ the practice, the participants were seated comfortably on the floor
171
+ in a cross-legged position. The practice consists of 2 distinct
172
+ stages. Each Trataka session involved a preparatory stage of eye
173
+ exercises for 10 min. These were performed with eyes open in a
174
+ well-lit, soundproofed recording room in the laboratory. During
175
+ this stage, the participants were asked to move the eyeballs in
176
+ horizontal, vertical, diagonal, and circular directions. The second

+ Trataka and Cognition
183
+ stage is the practice of gazing at the candle flame in a dark room,
184
+ where the candle was placed at the participant’s eye level at a
185
+ distance of 2 m. The participants were asked to fix their gaze
186
+ on the candle flame for about 2 to 3 min without blinking their
187
+ eyes. Then they were asked to visualize the candle flame between
188
+ the eyebrows with closed eyes. This process was repeated for
189
+ three rounds. Later, subjects were asked to defocus, and practice
190
+ concluded in silence with a prayer. This stage lasted for a total
191
+ duration of 10 min. A pre-recorded audio was used to maintain
192
+ uniformity of the practice among participants.
193
+ Eye Exercise Session
194
+ The eye exercise session included eyeball movements in the
195
+ horizontal, vertical, diagonal, and circular directions for 10 min
196
+ followed by 10 min of quiet sitting with closed eyes. The eyes open
197
+ part was performed in well-lit room, while the eyes closed part
198
+ was performed by switching offthe lights to maintain similarity
199
+ of interventions.
200
+ Assessments
201
+ Corsi-Block Tapping Task
202
+ Corsi-block tapping task is a popular neuro-psychological task
203
+ used to assess working and spatial memory. Nine blue squares
204
+ appear on the screen. For each trial, the squares "light up" as
205
+ yellow one by one in a varying sequence. After the presentation,
206
+ the participants had to click each of the boxes in a similar order
207
+ in which they have to "lit up" the first part of the task, i.e.,
208
+ forward tapping. In the second part of the task, they maintained
209
+ the reverse order, i.e., backward tapping (Kessels et al., 2008).
210
+ The task begins with a two-box sequence to a maximum of nine.
211
+ The test gets terminated when the participant cannot remember
212
+ the sequence for two consecutive trials at any one level. Hence,
213
+ the test assesses the following four variables: (i) forward Corsi
214
+ span, (ii) forward total score, (iii) backward Corsi span, and
215
+ (iv) the backward total score. Figure 1 illustrates the forward
216
+ and backward CBTT.
217
+ Presentation of Corsi-Block Tapping Task
218
+ We assessed the participants at baseline, following Trataka and
219
+ eye exercise sessions. The participants were asked to avoid
220
+ caffeine consumption on all the assessment days as it may
221
+ alter their cognitive abilities. The CBTT (Kessels et al., 2000,
222
+ 2008) was presented using the INQUISIT software package 4.0
223
+ (Millisecond Software, LLC, Seattle, WA, United States) on a
224
+ Dell desktop computer with a 21.5 color monitor. Uniform
225
+ configuration was maintained for the computers on which the
226
+ CBTT was presented to maintain the uniform processing speed.
227
+ All participants received a practice session prior to the actual
228
+ assessment session to familiarize themselves with the CBTT. The
229
+ experiment was conducted individually in a room under standard
230
+ fluorescent lighting in the research laboratory.
231
+ Data Analysis
232

264
+ DISCUSSION
265
+ The current study was designed to elicit if the practice of
266
+ Trataka affects the working and the spatial memory through the
267
+ performances in the CBTT. All the four measures, viz., forward
268
+ and backward Corsi spans, and total scores, demonstrated
269
+ significance within the subject’s effect. The Corsi span and total
270
+ scores were higher following Trataka while comparing with
271
+ baseline and Eye exercises. Scores following eye exercises and
272
+ baseline sessions were insignificant except in Forward total score.
273
+ The forward span and total score of CBTT measure material-
274
+ specific slave systems. The backward test measures primarily
275
+ tax central executive resources (Monaco et al., 2013). Thus,
276
+ improvements in both forward and backward span and total
277
+ scores indicated a positive effect of Trataka on working, spatial
278
+ memory, and executive functions while comparing with baseline
279
+ and eye exercises.
280
+ Earlier studies on Trataka and cognition have shown
281
+ improvements in the domains of selective attention, cognitive
282
+ flexibility, and response inhibition through the Stroop task
283
+ (Raghavendra and Singh, 2016; Sherlee and David, 2020).
284
+ Another study shown improvement in the performance of critical
285
+ flicker fusion after the immediate practice of Trataka in 35
286
+ volunteers (Mallick and Kulkarni, 2010). After the practice of
287
+ Trataka for 26 days, the performances of the digit span test, the
288
+ six-letter cancelation test, and the trail making test significantly
289
+ improved in thirty elderly subjects compared to the waitlist
290
+ control group (Talwadkar et al., 2014). Thus, improvements

434
+ practice of Trataka (Raghavendra and Ramamurthy, 2014). The
435
+ possible mechanisms for improving working and spatial memory
436
+ following the Trataka session could be the process of Trataka
437
+ itself, involving focused attention. This focused attention is
438
+ also elaborated in the Yoga Sutras (aphorisms) of Patanjali
439
+ (Taimni, 2010). A recent study has also demonstrated enhanced
440
+ mindfulness, attention, and reduced mind-wandering with the
441
+ practice of Trataka (Swathi et al., 2021). Thus, improved working
442
+ memory found in our study could be due to a reduction in
443
+ mind-wandering and enhanced focusing. The prefrontal cortex
444
+ is associated with memory, attention, executive functions, and
445
+ various other complex cognitive functions (Miller, 2000). Thus,
446
+ the results following the Trataka session could be due to
447
+ activation of the prefrontal cortex. However, further studies
448
+ with neuroimaging techniques may be required to confirm this
449
+ mechanism of action.
450
+ Another possible mechanism could be a surge in melatonin
451
+ release due to practice in the dim light. It is known that bright
452
+ light tunes the suprachiasmatic nucleus (SCN) that regulates the
453
+ circadian rhythm. Exposure to bright light impedes the melatonin
454
+ synthesis, whereas the dim light initiates the surge in melatonin
455
+ release (Zisapel, 2018). Melatonin has been found to positively
456
+ influence learning and memory (Zakaria et al., 2016). Thus,
457
+ further studies on Trataka may assess the serum melatonin levels
458
+ as one of the variables.
459
+ Our
460
+ study
461
+ indicated
462
+ a
463
+ beneficial
464
+ role
465
+ of
466
+ Trataka
467
+ in
468
+ enhancing the CBTT performance in healthy volunteers.
469
+ CBTT performance is commonly altered in neurodegenerative
470
+ disorders such as early-stage Parkinson’s (Stoffers et al., 2003)
471
+ and Alzheimer’s disease (Guariglia, 2007). Thus, future studies
472
+ may be planned in a clinical population, where the CBTT
473
+ performance is compromised.
474
+ Using a repeated measures design for immediate effect is
475
+ one of the strengths of the study. We also used a computer-
476
+ based program to execute CBTT, which enabled robust results
477
+ (Brunetti et al., 2014). The limitation of the study includes not
478
+ incorporating a neuro-imaging technique, which has limited
479
+ our ability to predict the exact mechanism of action. Thus,
480
+ future studies on Trataka and cognitive performance should
481
+ include neuroimaging techniques. Another major limitation of
482
+ the study is control condition which had eye exercise for
483
+ 10 min followed by 10 min of quiet sitting in which they
484
+ were told not to meditate. However, we are not sure if during
485
+ quiet sitting, if they focused on breathing or let their mind
486
+ wandered freely. We could not get an equal number of male
487
+ and female participants and were also unable to study the
488
+ impact of long-term practice of tataka. Lastly, the effect of
489
+ Trataka in a population with mild cognitive decline could be
490
+ studied in future.
491
+ CONCLUSION
492
+ The results of this study indicated a positive impact of the
493
+ Trataka session on the CBTT, indicating enhanced working
494
+ memory, spatial memory, and spatial attention among the
495
+ subjects compared to the baseline and eye exercise sessions.

+ Abstract. The self-rated musculoskeletal discomfort, hand grip strength, tapping speed, and low back and hamstring flexibility
13
+ (based on a sit and reach task) were assessed in 291 professional computer users. They were then randomized as Yoga (YG;
14
+ n = 146) and Wait-list control (WL; n = 145) groups. Follow-up assessments for both groups were after 60 days during which
15
+ the YG group practiced yoga for 60 minutes daily, for 5 days in a week. The WL group spent the same time in their usual
16
+ recreational activities. At the end of 60 days, the YG group (n = 62) showed a significant decrease in the frequency, intensity
17
+ and degree of interference due to musculoskeletal discomfort, an increase in bilateral hand grip strength, the right hand tapping
18
+ speed, and low back and hamstring flexibility (repeated measures ANOVA and post hoc analysis with Bonferroni adjustment).
19
+ In contrast, the WL group (n = 56) showed an increase in musculoskeletal discomfort and a decrease in left hand tapping speed.
20
+ The results suggest that yoga practice is a useful addition to the routine of professional computer users.
21
+ 1. Background of the study
22
+ There is extensive evidence that working with com-
23
+ puter terminals and keyboards is associated with the
24
+ development and exacerbation of a variety of work-
25
+ related disorders involving the back, neck, and upper
26
+ limbs [2]. These conditions are known as cumulative
27
+ trauma disorder (CTD). The National Institute for Oc-
28
+ cupational Safety and Health (NIOSH) estimated that
29
+ 15–20 percent of the workforce in the United States is
30
+ at risk of developingCTD [20]. In India a survey of 500
31
+ professional computer users showed that over 50 per-
32
+ cent of them had symptoms of established CTD [25].
33
+ Many investigators have identified the risk factors
34
+ that are closely related with CTD of the upper extrem-
35
+ ities. These include repetitive motion, excessive force,

41
+ and maintenance of awkward or constrained postures
42
+ for prolonged periods [1,16,27].
43
+ Various solutions to CTD include modifying work-
44
+ stations, using alternative keyboards and pointing de-
45
+ vices, and adopting software solutions to minimize the
46
+ key presses required to execute elaborate routines [33].
47
+ However these are only partial solutions to CTD. It
48
+ is essential to keep professional computer users aware
49
+ about injurious keyboard techniques, as well as pos-
50
+ tures and working styles which place them at risk [14,
51
+ 22].
52
+ Apart from this there have been studies to evaluate
53
+ the impact of lifestyle on the prevention of CTD while
54
+ complementary treatments have been used in the man-
55
+ agement of this condition. A cross-sectional survey
56
+ of 134,072 respondents in Canada, showed that being
57
+ physically active during leisure time was associated
58
+ with a lower prevalence of work-related upper body
59
+ CTD compared to the general prevalence of 5.9 percent
60
+ in the Canadian population [24].
61
+ In the management of CTD various combinations
62
+ of exercise and health awareness strategies have been

68
+ basic physiological understanding of the disorder have
69
+ been found effective in reducing stiffness and pain of
70
+ the upper back and neck in CTD [23]. There is also
71
+ some evidence to indicate that splinting, laser acupunc-
72
+ ture, yoga and therapeutic ultrasound may be effec-
73
+ tive in the short to medium term (i.e., up to 6 months)
74
+ management of carpal tunnel syndrome [10]. This was
75
+ based on an assessment of two systematic reviews, six-
76
+ teen randomized controlled trials (RCTs) and a single
77
+ before-and-after study using historical controls.
78
+ An
79
+ earlier RCT did indicate the benefits of yoga over splint-
80
+ ing for carpal tunnel syndrome [9]. In this trial the ben-
81
+ efit was derived from practicing eleven yoga postures
82
+ intended to strengthen, stretch, and balance each joint
83
+ in the upper body, practiced along with relaxation given
84
+ twice weekly, for eight weeks. Following yoga the par-
85
+ ticipants showed a significant decrease in pain and an
86
+ increase in grip strength whereas a control group (who
87
+ were given a wrist splint to supplement their treatment)
88
+ showed no change.
89
+ The hand grip strength measures muscle strength and
90
+ endurance in the hand and forearm muscles.
91
+ Expe-
92
+ rienced computer users with symptoms of discomfort
93
+ in the hand-wrist and forearm-elbow had lower pinch
94
+ grip strength than those who were asymptomatic [15].
95
+ In a separate study on normal volunteers and patients
96
+ with rheumatoidarthritis, the hand grip strength of both
97
+ hands measured with a grip dynamometer increased
98
+ in normal adults, children and in rheumatoid arthritis
99
+ patients following yoga practice which included yoga
100
+ postures (asanas), voluntarily regulated yoga breathing
101
+ (pranayamas), and meditation (dhyana) [5]. An equal
102
+ number of normal adults, children, and patients with
103
+ rheumatoid arthritis who did not practice yoga showed
104
+ no increase in hand grip strength, suggesting that there
105
+ was no re-test effect. Given the fact that symptomatic
106
+ computer users did have a lower pinch grip strength
107
+ and that hand grip strength has been shown to improve
108
+ with yoga practice [5,28] in the present study hand grip
109
+ strength was assessed in professional computer users
110
+ following yoga.
111
+ In an earlier study another aspect of motor func-
112
+ tion, viz., motor speed, was also found to improve fol-
113
+ lowing thirty days of practicing a combination of yo-
114
+ ga postures, breathing techniques and meditation ev-
115
+ ery day [4]. The number of successive, rapid alternat-
116
+ ing movements in a given time, as in a tapping speed
117
+ task, is a standard measure to clinically evaluate motor
118
+ speed [26]. Following thirty days of yoga the tapping
119
+ speed increased in the first ten seconds of the thirty-
120
+ second tapping speed task. This showed that motor
121
+ speed for repetitive finger movements increased fol-
122
+ lowing yoga, but since the increase was not sustained
123
+ for thirty seconds, it suggested that endurance was not
124
+ improved. In the present study it was considered rele-
125
+ vant to study the tapping speed based on a report that in
126
+ contrast to earlier biomechanicaltheories, the key press
127
+ force and key press speed were negatively associated
128
+ with musculoskeletal discomfort [18]. In particular,
129
+ slower key press speeds were associated with higher
130
+ levels of right shoulder discomfort and fatigue.
131
+ The effect of yoga practice on the hand grip strength
132
+ and tapping speed have not been studied in professional
133
+ computer users who are potentiallyat risk of developing
134
+ CTD
135
+ 2. Methods
136
+ 2.1. Purpose of the study
137
+ The present randomized controlled trial was con-
138
+ ducted to assess the effect of sixty days of yoga practice
139
+ on musculoskeletal discomfort, motor functions (viz.,
140
+ strength and motor speed) and hip and lower back flex-
141
+ ibility in professional computer users. This research
142
+ may help to develop a yoga module attending to the
143
+ specific requirements of professional computer users.
144
+ 2.2. Sampling
145
+ Two hundred and ninety one persons working in a
146
+ software company in Bangalore, India were recruited
147
+ for the study. All the participants in the study used
148
+ a computer for at least 6 hours each day, for 5 days
149
+ in a week. Persons of both sexes with ages ranging
150
+ between 21 and 49 years participated in the trial. The
151
+ following conditions were the basis for excluding par-
152
+ ticipants from the trial: (i) those who reported symp-
153
+ toms of musculoskeletaldiscomfort(neck/shoulderand
154
+ hand/arm) during a clinical examination, requiring the
155
+ use of analgesics and (ii) subjects who were left hand
156
+ dominant. Hand dominancewas assessed using the Ed-
157
+ inburgh handedness inventory [21]. All subjects were
158
+ right hand dominant. None of the participants had to
159
+ be excluded based on the criteria mentioned above.
160
+ Both groups had comparable job assignments and
161
+ responsibilities based on rating by the human resource
162
+ personnel from the software company.
163
+ All of them
164

193
+ The details of the study were explained to the partic-
194
+ ipants and their consent to participate in the study was
195
+ obtained. The project was approved by the ethics com-
196
+ mittee of the research foundation and had the approval
197
+ of the human resource department of the software com-
198
+ pany.
199
+ 2.3. Design
200
+ The 291 participants were randomizedas two groups
201
+ using a standard random number table prior to their as-
202
+ sessment. The two groups were then designated as (i)
203
+ intervention (i.e., yoga, n = 146) and (ii) wait list con-
204
+ trol (n = 145), by a person from the software company
205
+ who had no other part in the study. The yoga (YG) and
206
+ wait list control (WL) groups were comparable with
207
+ respect to their age [group average (± S.D.) 32.8 (±
208
+ 8.6) years and 31.9 (± 10.2) years, respectively], gen-
209
+ der distribution [11 females in YG group and 13 in WL
210
+ group], the type of work they did, their workstations
211
+ and the number of hours they used a computer each
212
+ day.
213
+ Both groups were assessed at baseline and after
214
+ 60 days. During the 60 days the YG group had an
215
+ hour of yoga practice each day, for five days in a week.
216
+ While the YG group practiced yoga the WL group spent
217
+ the time in the recreation center of the software com-
218
+ pany where 60 percent of them talked to their friends,
219
+ 12 percent spent time playing indoor games, 12 percent
220
+ exercised in the gym and 16 percent watched television.
221
+ The WL group had already been spending this time
222
+ each day doing the same activities and hence during
223
+ the 60 day period they were following their usual rou-
224
+ tine. Hence the wait-list control group served mainly to
225
+ assess the changes related to repeated-testing after 60
226
+ days. During the 60 days there were 84 drop outs from
227
+ the trial in the YG group and 89 from the WL group.
228
+ The large number of drop outs was mainly due to the
229
+ fact that the participants had demanding work sched-
230
+ ules which interfered with their participating in: (i) the
231
+ intervention (YG group) or recreational activities (WL
232
+ group) and/or (ii) the assessments (both YG and WL
233
+ groups). Most of the participants who were consid-
234
+ ered as ‘drop-outs’ had been posted to other companies
235
+ elsewhere during the two month study period. To be
236
+ considered as regular in their participation they had to
237
+ have a minimum of 38 days of attendance during the
238
+ 60 day period. The trial profile is given in Fig. 1.
239
+ These details as well as the trial profile have been
240
+ provided in an earlier report of the effects of this yoga
241
+ programon symptoms of visual discomfort(i.e., of ‘dry
242
+ eye’) [29].

+ 2.4.1. Musculoskeletal and hand discomfort
245
+ The Cornell Musculoskeletal Discomfort Question-
246
+ naire (CMDQ) The Cornell Musculoskeletal Discom-
247
+ fort Questionnaire (CMDQ) is a questionnaire which
248
+ combines a body map diagram with questions about
249
+ the seven day prevalence of musculoskeletal pain,
250
+ its’ severity, and if it interfered with performing
251
+ job duties.
252
+ This questionnaire was used in a 1999
253
+ study of musculoskeletal discomfort among keyboard
254
+ users [12]. Since this survey was based on another in-
255
+ strument called the Nordic Musculoskeletal Question-
256
+ naire (NMQ), it was concluded that the CMDQ had
257
+ 300
258
+ S. Telles et al. / Yoga and motor functions in computer professionals
259
+ the same validity [12] The CMDQ has face validity
260
+ and test-retest reliability, though this was studied over
261
+ a three week period [12]. The main limitations of this
262
+ instrument are the lack of clinical validity testing for it
263
+ specifically and the fact that it is primarily developed
264
+ for use in upper body disorders. The tool does not as-
265
+ sess if the musculoskeletal discomfort is work-related.
266
+ The CMDQ was used to assess: (i) frequencyof pain
267
+ episodes during the last work week at: neck; shoulder;
268
+ elbow; arm; wrist; hands and fingers, (ii) the inten-
269
+ sity of pain expressed as level of discomfort and (iii)
270
+ the interference with the ability to work. The symp-
271
+ toms were considered during the week before assess-
272
+ ment. The scores were analyzed by weighting the rat-
273
+ ing scores to more easily identifythe most serious prob-
274
+ lems and summing the rating values for each person
275
+ for the whole body, right hand and left hand separately
276
+ as follows. For frequency the rating was: Never = 0,
277
+ 1–2 times/week = 1.5, 3–4 times/week = 3.5, Every
278
+ day = 5, and Several times every day = 10. The level
279
+ of discomfort scores were analyzed as: Slightly = 1,
280
+ Moderately uncomfortable = 2, and Very uncomfort-
281
+ able = 3. The Interference scores were rated as: Not
282
+ at all = 1, Slightly interfered = 2, and Substantially
283
+ interfered = 3.
284
+ The person who administered the questionnaire and
285
+ scored the response sheets was not aware to which
286
+ group the subjects belonged.
287
+ 2.4.2. Hand grip strength
288
+ Hand grip strength of both hands was assessed us-
289
+ ing a hand grip dynamometer (Lafayette Instruments,
290
+ Model No. 76618, Indiana, USA). Subjects were tested
291
+ in 6 trials, 3 for each hand alternately, with a gap of
292
+ 10 seconds between trials. During the assessment sub-
293
+ jects were asked to keep their arm extended at shoul-
294
+ der level, horizontal to the ground, with extension at
295
+ the elbow as has been described earlier [5]. The max-
296
+ imum value obtained during the three trials was used
297
+ for statistical analysis.
298
+ 2.4.3. Tapping speed
299
+ Tapping speed was measured using an apparatus con-
300
+ sisting of an 18 inch fiber-resin board with two rect-
301
+ angular metal plates on either end, 11 inches apart
302
+ (Lafayette Instruments, Model No. 32012, Indiana,
303
+ USA) The apparatus has a metal stylus connected to
304
+ it and contacts between the stylus and the two metal
305
+ plates are registered on an impulse counter. Subjects
306
+ were instructed to use their right hand to hold the stylus
307
+ and tap on the steel plate which is on the right side
308
+ of the board, and to use their left hand for the board
309
+ on the left side. They were asked to tap as rapidly as
310
+ possible. The apparatus was kept on a table at the level
311
+ which the keyboard was kept and tapping was carried
312
+ out with the wrist supported and the stylus held as a
313
+ pen is held. Assessments were made for both hands,
314
+ and the order of testing a particular hand was alternated
315
+ for different subjects. Tapping speed was assessed in
316
+ three contiguous periods of 10 seconds. This was done
317
+ separately for each hand.
318
+ 2.4.4. Low back and hamstring flexibility
319
+ Low back and hamstring flexibility were assessed
320
+ using a standard sit-and-reach apparatus (Lafayette In-
321
+ struments, Model No. 01285, Indiana, USA) and fol-
322
+ lowing a standard method [7]. The test involves sitting
323
+ on the floor with legs out straight ahead. Bare feet
324
+ are placed with the soles flat against the box, shoulder-
325
+ width apart. Both knees are held flat against the floor
326
+ by the tester.
327
+ With hands on top of each other and
328
+ palms facing down, the subject reaches forward along
329
+ the measuring line as far as possible, sliding a plate
330
+ with a marker, along the scale as far forward as possi-
331
+ ble. After one practice reach, the second reach is held
332
+ for at least two seconds while the distance is record-
333
+ ed. It is made sure that there are no jerky movements,
334
+ and that the fingertips remain level and the legs flat.
335
+ The distance to which the plate and indicator are slid
336
+ forward are recorded to the nearest cm.
337
+ 2.5. Intervention
338
+ The yoga sessions were taught by an instructor who
339
+ had completed a one year diploma in yoga at an uni-
340
+ versity recognized by the Indian government. He had
341
+ taken up the diploma after graduation. After this he had
342
+ been teaching yoga to people with normal health for
343
+ ten years at the time the project commenced. The yoga
344
+ sessions were conducted in a room set aside for the em-
345
+ ployees’ recreational use which was located within the
346
+ company premises. The yoga sessions were conducted
347
+ during a 1 hour period set aside for recreation between
348
+ 17.30 and 18.30 hours each day. The participants’ yoga
349
+ practice and attendance of the sessions were monitored
350
+ by the yoga instructor.
351
+ The 60 minute yoga program included yoga postures
352
+ (asanas, 15 minutes), exercises for the joints and back
353
+ (sithilikarana vyayama, 10 minutes), regulated breath-
354
+ ing (pranayamas, 10 minutes), visual cleansing exer-
355
+ cises (trataka, 10 minutes), and guided relaxation (15
356
+ minutes). These techniques were selected based on pre-
357
+ S. Telles et al. / Yoga and motor functions in computer professionals
358
+ 301
359
+ (i) Yoga posture (asana)
360
+ (ii) Regulated yoga breathing

366
+ vious research which has shown that practicing them re-
367
+ duced musculoskeletal discomfort [11], increased grip
368
+ strength [5] and tapping speed [4]. Figure 2 shows a
369
+ single individual practicing (i) a yoga posture or asana,
370
+ (ii) voluntarily regulated yoga breathing (pranayama),

374
+ 2.6. Data analysis
375
+ The data were analyzed using SPSS Version 10.0.
376
+ 2.6.1. Musculoskeletal and hand discomfort
377
+ Three repeated measures analyses ofvariance (ANO-
378
+ VA) were carried out separately for the frequency, dis-
379
+ comfort and level of interference, with one Between-
380
+ subjects factor, viz., Groups (with two levels, i.e., YG
381
+ and WL groups) and two Within-subjects factors, viz.,
382
+ Assessments (with two levels, i.e., day 1 and day 60)
383
+ and Sites (with three levels, i.e., whole body, right hand
384
+ and left hand).
385
+ Post-hoc analyses using pair wise comparisons be-
386
+ tween day 1 and day 60, for the whole body, right hand
387
+ and left hand were done separately, with Bonferroni
388
+ adjustment.

+ S. Telles et al. / Yoga and motor functions in computer professionals
391
+ 2.6.2. Hand grip strength and tapping speed
392
+ The hand grip strength data were analyzed with re-
393
+ peated measures analyses of variance (ANOVA) with
394
+ one Between-subjects factor, viz., Groups (with two
395
+ levels, i.e., YG and WL groups) and two Within-
396
+ subjects factors, viz., Assessments (with two levels,
397
+ i.e., day 1 and day 60) and Hands (with two levels, i.e.,
398
+ right hand and left hand).
399
+ For the tapping speed the numberof contacts made in
400
+ specified time intervals were analyzed with an ANOVA
401
+ which had one Between-subjects factor, viz., Groups
402
+ (with two levels, i.e., YG and WL groups) and three
403
+ Within-subjects factors, viz., Assessments (with two
404
+ levels, i.e., day 1 and day 60), Hands (with two levels,
405
+ i.e., right hand and left hand) and Time (with three
406
+ levels, i.e., 10 sec., 20 sec. and 30 sec.).
407
+ Post-hoc analyses for pair wise comparisons between
408
+ mean values were done with Bonferroni adjustment.
409
+ 2.6.3. Low back and hamstring flexibility
410
+ The data were analyzed with an ANOVA for repeat-
411
+ ed measures with one Between-subjects factor, viz.,
412
+ Groups (with two levels, i.e., YG and WL groups) and
413
+ one Within-subjects factor, viz., Assessments (with two
414
+ levels, i.e., day 1 and day 60).
415
+ Post-hoc analyses for pair wise comparisons between
416
+ mean values were done with Bonferroni adjustment.
417
+ 3. Results
418
+ 3.1. The repeated measures ANOVA
419
+ 3.1.1. Musculoskeletal discomfort
420
+ The repeated measures ANOVA showed a significant
421
+ difference between the two groups i.e., YG and WL
422
+ groups (F = 7.448, DF = 1.116, p < 0.01). There
423
+ was also a significant difference between the three sites
424
+ i.e., body as a whole, right hand and left hand (F =
425
+ 146.799, DF = 1.125, 130.460, p < 0.001; Huynh-
426
+ Feldtε = 0.562) and the three indicators of discomfort
427
+ i.e., frequency, severity and interference (F = 67.107,
428
+ DF = 1.200, 139.929, p < 0.001; Huynh-Feldt ε =
429
+ 0.603). There was a significant interaction between
430
+ assessments [day 1 and day 60] and sites (F = 6.928,
431
+ DF = 1.376, 153.806, p < 0.01]; Huynh-Feldtε =
432
+ 0.663); and between sites and indicators of discom-
433
+ fort (F = 36.617, DF = 1.283, 148.779 p < 0.001;
434
+ Huynh-Feldtε = 0.321). This suggests that these fac-
435
+ tors were not independent of each other [34].
436
+ 3.1.2. Hand grip strength and tapping speed
437
+ The repeated measures ANOVA showed a signifi-
438
+ cant difference in hand grip strength between Assess-
439
+ ments (F = 9.658, DF = 1,116, p < 0.01) and Hands
440
+ (F = 11.524, DF = 1,116, p < 0.01). There was no
441
+ difference between the YG and WL group.
442
+ The tapping speed showed a significant difference
443
+ between Hands (F = 27.854, DF = 1,116, p < 0.001)
444
+ and Time, that is 10, 20 and 30 seconds (F = 21.451,
445
+ DF = 2, 232, p < 0.001). The interaction between
446
+ Assessments and Hands (F = 5.755, DF = 1,116, p <
447
+ 0.05) was also significantly different. This suggests
448
+ that the effect of one factor was not independent of a
449
+ particular level of the other factor(s) [34]. There was
450
+ no difference between the YG and WL group.
451
+ 3.1.3. Low back and hamstring flexibility
452
+ The repeated measures ANOVA showeda significant
453
+ difference between the two groups i.e., YG and WL
454
+ groups (F = 4.934, DF = 1,116, p < 0.05). There
455
+ was a significant difference in sit and reach scores be-
456
+ tween assessments (F = 58.556, DF = 1,116, p <
457
+ 0.001).
458
+ 3.2. Post-hoc analyses
459
+ 3.2.1. Musculoskeletal discomfort
460
+ Post-hoc analyses by pair wise comparisons with
461
+ Bonferroni adjustment for the YG group showed a sig-
462
+ nificant decrease following two months of yoga com-
463
+ pared to before, in the frequency of discomfort for the
464
+ whole body (p < 0.001), right hand (p < 0.001) and
465
+ the left hand (p < 0.01). The level of discomfort also
466
+ decreased at the three sites mentioned above (p < 0.01
467
+ in all cases). There was also a decrease in the extent to
468
+ which discomfort interfered with their routine work in
469
+ the three sites mentioned above (p < 0.01 for the whole
470
+ body and the right hand; p < 0.05 for the left hand).
471
+ In contrast, the WL group showed a significant in-
472
+ crease in frequency of discomfort for the whole body
473
+ (p < 0.001), the right hand (p < 0.001) and the left
474
+ hand (p < 0.001). The level of discomfort also in-
475
+ creased at the three sites mentioned above (p < 0.001
476
+ in all cases) respectively. There was also an increase
477
+ in the extent to which discomfort interfered with their
478
+ routine work at the same three sites (p < 0.001 in all
479
+ cases).

569
+ 4. Discussion
570
+ In the present study eight weeks of yoga practice sig-
571
+ nificantly decreased self–reported musculoskeletal dis-
572
+ comfort in 62 professional computer users. Also, they
573
+ showed an increase in the bilateral hand grip strength,
574
+ the tapping speed of the right hand, and an increase
575
+ in low back and hamstring flexibility based on a stan-
576
+ dard sit and reach task. In contrast, after sixty days
577
+ of no-intervention and carrying on with their routine
578
+ recreational activities 55 professional computer users
579
+ who formed the WL group showed an increase in mus-
580
+ culoskeletal discomfort and a decrease in left hand tap-
581
+ ping speed.
582
+ Earlier, musculoskeletal discomfort and pain of the
583
+ hands, neck and back were shown to be associated
584
+ with different psychosocial factors [8]. For example,
585
+ increased physical workload, such as an increase in
586
+ work pressure and greater time spent at a computer was
587
+ related to symptoms in the neck, shoulder, hand and
588
+ wrist [3]. Conversely neck and low back discomfort
589
+ were associated with mental distress related to either
590
+ of two extremes viz., monotonous work [13] or a high
591
+ mental work demand [30]. This suggests that greater
592
+ mental workload has a bigger impact on discomfort of
593
+ the neck and back, whereas upper limb discomfort may
594
+ be more closely related to a physical work load.
595
+ The decrease in discomfortfollowing yoga was com-
596
+ parable for the whole body, the right hand and the left
597
+ hand. In contrast, the WL group showed an increase in
598
+ the level of discomfort after eight weeks. The level of
599
+ discomfort was high for the left hand (277.4 percent)
600
+ and for the right hand (106.7 percent) compared to the
601
+ body as a whole (40.4 percent). Hence while the mus-
602
+ culoskeletal discomfort increased to a greater extent
603
+ in both hands than in the rest of the body, in the WL
604
+ group, the improvement in the YG group was compa-
605
+ rable at all three sites. Here, musculoskeletal discom-
606
+ fort was assessed using a subjective rating scale, not
607
+ some more objective method. Given the fact that it was
608
+ more likely that the WL (control group) felt deprived
609
+ of the additional care in the form of interaction with
610
+ the yoga teacher, which the yoga group had, this could
611
+ possibly have made the control group more likely to
612
+ experience and express subjectively rated discomfort.
613
+ This is specially possible since additional care (in this
614
+ case interaction with the yoga therapist), is known to
615
+ have psychological benefits [6].
616
+ In another study, experienced computer users with
617
+ symptoms of discomfort in the hand-wrist and forearm-
618
+ elbow had no difference in their hand grip strength

686
+ but had lower pinch grip strength than those who were
687
+ asymptomatic [15]. These observations are comparable
688
+ to those of the WL group in the present study that
689
+ showed no change in hand grip strength after eight
690
+ weeks with no specific intervention.
691
+ In an earlier study a combination of yoga practices
692
+ which included postures, breathing techniques, and
693
+ meditation, increased the hand grip strength in physical
694
+ activity instructors, over a three month period [28]. In
695
+ another study the hand grip strength also increased in
696
+ children after 10 days of practice and adults after 30
697
+ days of practice [5]. In the same report, patients with
698
+ rheumatoid arthritis showed an increase in hand grip
699
+ strength after a 15 day period of yoga practice. In-
700
+ creased hand grip strength following varying durations
701
+ of yoga practice may be related to the availability of
702
+ energy and oxidation of glucose, as these factors are
703
+ known to influence grip strength [19].
704
+ While increased hand grip strength after yoga sug-
705
+ gests an increase in muscle strength and endurance,
706
+ similar results were not seen in another study which ex-
707
+ amined the impact of yoga on a thirty seconds tapping
708
+ speed task [4], In this earlier study, following a month
709
+ of yoga practice the tapping speed, which is correlated
710
+ with motor speed for repetitive movements increased
711
+ within the first ten seconds of the task. However when
712
+ the participants continued the task for three contiguous
713
+ 10 second periods, the tapping speed was significantly
714
+ lower in the last 10 seconds for both yoga and con-
715
+ trol groups at both pre and post assessments. Hence
716
+ for this repetitive and continuous task yoga practice
717
+ did not reduce fatigue. Here, the increase in tapping
718
+ speed could have been an initial spurt of speed which
719
+ was not sustained. In contrast, in the present study,
720
+ the increase in tapping speed in the YG group was
721
+ seen after 10 and 30 seconds, with a non-significant
722
+ trend of increase at 20 seconds. Hence these results
723
+ suggest that the increase in motor speed was sustained
724
+ over 30 seconds. Motor speed is determined by muscle
725
+ strength, endurance, and co-ordination. An increase in
726
+ some, or all, of these factors may have contributed to
727
+ the increase in tapping speed. However the increase in
728
+ right hand tapping speed, with no increase for the left
729
+ hand is difficult to explain. This is especially difficult
730
+ to explain as frequent use of a computer keyboard was
731
+ shown to increase left hand performance scores on a
732
+ dexterity task [30].
733
+ In contrast to the YG group the WL group showed a
734
+ decrease in left hand tapping speed during the first ten
735
+ seconds, at the end of eight weeks. This may have been
736
+ related to work fatigue during the eight week period.
737
+ However, the decrease in the initial speed could also be
738
+ related to psychological factors [31,32] and poor moti-
739
+ vation for the task in the absence of an intervention [6].
740
+ The latter point is related to the fact that in the absence
741
+ of being given an intervention the WL group may not
742
+ have felt that their performance was likely to change
743
+ and hence may not have been enthusiastic at re-test.
744
+ The increased scores in the sit and reach task fol-
745
+ lowing yoga are suggestive of an increase in hamstring
746
+ and low back flexibility. Improved flexibility is asso-
747
+ ciated with a lower risk of developing muscle tension
748
+ and pain [17]. This may have also contributed to the
749
+ decreased musculoskeletal discomfort following yoga.
750
+ There were two main limitations to the study. One
751
+ limitation was the large numbers of drop-outs from both
752
+ groups. The main reason why participants dropped out
753
+ of the study was because they had job assignments for
754
+ which they were posted elsewhere in or outside India.
755
+ Out of 57 drop-outs from the YG group, who were
756
+ not able to regularly attend the intervention, 6 of them
757
+ dropped out as they preferred to use the 60 minute peri-
758
+ S. Telles et al. / Yoga and motor functions in computer professionals
759
+ 305
760
+ od kept aside for recreation for some activity other than
761
+ yoga. The majority dropped out as they were posted
762
+ elsewhere. A second limitation is that the intervention
763
+ was for 60 minutes, for 5 days each week. This would
764
+ require special commitment for the participants to set
765
+ aside this amount of time on all working days. The
766
+ yoga program was designed to address at least three
767
+ problems which are known to arise in computer users.
768
+ These are musculoskeletal discomfort, symptoms of
769
+ visual discomfort, and mental stress. However future
770
+ research needs to be carried out to determine whether
771
+ the duration of the program could be shortened and still
772
+ get the same benefits.
773
+ 5. Conclusion
774
+ In summary the present trial showed that yoga prac-
775
+ ticed for an hour a day, 5 days in a week, for sixty
776
+ days decreases self rated musculoskeletal discomfort,
777
+ improves muscle strength and speed and low back and
778
+ hamstring flexibility. These results suggest that yoga is
779
+ a useful addition to the routine of professional comput-
780
+ er users. Based on this, employees of software com-
781
+ panies would need to commit 5 hours a week for yoga
782
+ practice and their employers would need to facilitate
783
+ this in terms of providinga place to practice yoga, time,
784
+ and arranging for informed instruction on yoga.
785
+ 6. Recommendations for future studies
786
+ In the present study theyoga program was for 60min-
787
+ utes, 5 days in a week. Future research could be planned
788
+ to determine the usefulness of a shorter duration yoga
789
+ program. Also, it would be useful to determine whether
790
+ practicing yoga for some days as part of a group and for
791
+ the remaining days at home using pre-recordedinstruc-
792
+ tions and maintaining a diary, would also be effective.
793
+ These options could make it easy for more participants
794
+ to comply with the program.
795
+ The present randomized controlled trial was limited
796
+ to a sixty day follow-up period. Further studies could
797
+ be planned with a longer duration follow-up period. It
798
+ would also be desirable to study whether yoga prac-
799
+ tice prevents the development of CTD in professional
800
+ computer users.

+ INTRODUCTION
18
+ The diagnosis and treatment of breast cancer can pose
19
+ a considerable amount of physical, psychological, and
20
+ emotional distress,[1-3] and affects about 80% of the
21
+ patients during initial stages of their treatment.[3] Though
22
+ advancements in the treatment of cancer have improved
23
+ survival rates in cancer patients, they have to endure
24
+ distressing symptoms for a longer time than ever before.
25
+ Patients with breast cancer normally receive multimodal
26
+ treatment over a long period of time[4,5] and experience
27
+ a multitude of symptoms that grossly affect their overall
28
+ quality of life and survival. As patients live longer with
29
+ cancer, concern is growing about both the health-related
30
+ quality of life of those diagnosed with cancer and the quality
31
+ Objectives: This study compares the effects of an integrated yoga program with brief supportive therapy on distressful
32
+ symptoms in breast cancer outpatients undergoing adjuvant radiotherapy.
33
+ Materials and Methods: Eighty-eight stage II and III breast cancer outpatients were randomly assigned to receive yoga
34
+ (n = 44) or brief supportive therapy (n = 44) prior to their radiotherapy treatment. Intervention consisted of yoga sessions
35
+ lasting 60
36
+ min daily while the control group was imparted supportive therapy once in 10 days during the course of their
37
+ adjuvant radiotherapy. Assessments included Rotterdam Symptom Check List and European Organization for Research in
38
+ the Treatment of Cancer—Quality of Life (EORTC QoL C30) symptom scale. Assessments were done at baseline and after
39
+ 6 weeks of radiotherapy treatment.
40
+ Results: A GLM repeated-measures ANOVA showed a signifi
41
+ cant decrease in psychological distress (P = 0.01), fatigue
42
+ (P = 0.007), insomnia (P = 0.001), and appetite loss (P = 0.002) over time in the yoga group as compared to controls. There
43
+ was signifi
44
+ cant improvement in the activity level (P = 0.02) in the yoga group as compared to controls. There was a signifi
45

46
+ positive correlation between physical and psychological distress and fatigue, nausea and vomiting, pain, dyspnea, insomnia,
47
+ appetite loss, and constipation. There was a signifi

72
+ meanings for the symptoms and decide how to respond to
73
+ them.[10] The perceived discomfort experienced in relation
74
+ to the symptom can lead to anxiety and depression if
75
+ patients are unable to cope with this distress. This can
76
+ significantly impact patient outcomes in terms of quality
77
+ of life, functional and emotional status, compliance to
78
+ treatment, self-care and management, mortality, and
79
+ morbidity.[11-13] Therefore adopting symptom management
80
+ strategies that reduce symptom experience can significantly
81
+ benefit the patient’s activity, functioning, and health
82
+ outcomes. Although research is producing new insights
83
+ into the causes of and cures for cancer, efforts to manage
84
+ the symptoms of the disease and its treatment have not
85
+ kept pace. Evidence suggests that pain is frequently
86
+ undertreated. Patients and health care providers have
87
+ reported depression and a persistent lack of energy as
88
+ the aggressiveness of therapy has been increased and/or the
89
+ underlying malignancy has worsened. The challenge is to
90
+ increase awareness of the importance of recognizing and
91
+ actively addressing cancer-related symptoms when they
92
+ occur. Specifically, we need to be able to identify who is
93
+ at risk for cancer-related pain, depression, and/or fatigue;
94
+ what treatments work best to address these symptoms when
95
+ they occur; and how best to deliver interventions across
96
+ the continuum of care.[6]
97
+ Various psychosocial interventions and behavioral
98
+ approaches have been used over the decades to alleviate
99
+ distress and reduce distressing side effects or symptoms
100
+ in these populations.[14-19] Preliminary findings suggest
101
+ beneficial effects for yoga in improving mood, coping,
102
+ adjustment, and decrease in distressful symptoms such as
103
+ loss of appetite and fatigue in cancer patients. However,
104
+ subjects in these studies were a heterogeneous mix of
105
+ cancer patients in varying stages of disease and treatment.
106
+ Since cancer patients experience a multitude of symptoms
107
+ of varying clusters at various stages of their disease and
108
+ conventional treatment, it is difficult to ascertain if yoga
109
+ intervention is beneficial in reducing a group of symptoms
110
+ that are specific to the treatment and stage of their disease.
111
+ It has also been shown that most of these symptoms
112
+ may persist even after completion of treatment thereby
113
+ impacting their quality of life. Managing these symptoms
114
+ effectively during the early course of treatment has been
115
+ shown to improve patient outcomes during later stages of
116
+ their disease.
117
+ In this study, we compare the effects of “integrated yoga
118
+ program” with “brief supportive therapy” on symptom
119
+ control in early operable breast cancer patients undergoing
120
+ adjuvant radiotherapy.
121
+ MATERIALS AND METHODS
122
+ Though the primary objective in our study was to evaluate
123
+ effects of yoga on quality of life, the secondary objective
124
+ was to evaluate its effects on symptom control. In this
125
+ paper, we focus on effects of yoga in managing distressful
126
+ symptoms in early breast cancer patients receiving
127
+ adjuvant radiotherapy.
128
+ Subjects
129
+ Eighty-five recently diagnosed women with stage II and III
130
+ breast cancer from two different urban cancer centers were
131
+ recruited for this study over a 2-year period from January 2004
132
+ to June 2006. All subjects had undergone primary treatment
133
+ as surgery and were receiving adjuvant radiotherapy. Patients
134
+ were eligible to participate in this study if they met the
135
+ following selection criteria at the start of the study: (i) women
136
+ with recently diagnosed operable breast cancer, (ii) age
137
+ between 30 and 70 years, (iii) Zubrod’s performance status 0-2
138
+ (ambulatory >50% of time), (iv) high-school education, and
139
+ (v) written consent to participate in the study. Subjects were
140
+ excluded if they had (i) any concurrent medical condition
141
+ that was likely to interfere with the treatment, (ii) major
142
+ psychiatric, neurological illness or autoimmune disorders,
143
+ and (iii) any known metastases. Each study participant was
144
+ prescribed adjuvant radiotherapy with a cumulative dose of
145
+ 50.4 Gy with fractionations spread over 6 weeks. The details
146
+ of the study were explained to the participants and their
147
+ informed consent was obtained in writing.
148
+ Randomization
149
+ Of the 103 eligible participants, 88 (85.4%) consented to
150
+ participate and were randomized to receive yoga (n = 44)
151
+ or supportive therapy (n = 44) initially before intervention
152
+ (prior to radiotherapy) using computer-generated random
153
+ numbers. Randomization was performed using concealed
154
+ allocation protocol into two study arms. Personnel who had
155
+ no part in the trial performed randomization.
156
+ Sample size
157
+ The primary hypothesis of the study was to evaluate the
158
+ effects of yoga intervention on the improvement in quality-
159
+ of-life measures. Earlier study with Mindfulness-Based
160
+ Stress Reduction Program (MBSR) had shown a modest effect
161
+ size (ES = 0.38) on EORTC QoL C30 global quality-of-life
162
+ measure. We used G power to calculate the sample size with
163
+ α = 0.05 and β = 0.2, and the above-mentioned effect size of
164
+ 0.38 for repeated-measures ANOVA between factor effects.
165
+ The sample size thus required was n = 44 in each group.
166
+ Among the 88 participants, 75 (yoga, n = 42; control,
167
+ n = 33) completed their prescribed radiation therapy
168
+ of 6 weeks and follow-up assessment. There were 13
169
+ dropouts in the study [Figure 1]. The reasons for dropouts
170
+ were migration to other hospitals (n = 4), use of other
171
+ complementary therapies (e.g., homeopathy or ayurveda)
172
+ (n = 2), refusal to continue the study (n = 2), time

179
+ Measures
180
+ Before randomization demographic information, medical
181
+ history, and clinical data were ascertained from all
182
+ consenting participants.
183
+ Rotterdam symptom check list
184
+ Participants completed the Rotterdam Symptom Check
185
+ List (RSCL) that measures symptoms that cause physical
186
+ distress, psychological distress, and impairment in the
187
+ activities of daily living. The RSCL is a 39-item scale
188
+ which has been widely used as a brief measure of quality
189
+ of life in cancer patients. It covers important domains
190
+ of psychological distress, physical status (disease and
191
+ treatment items), functional status, and global quality
192
+ of life. Evidence of its reliability and validity has been
193
+ found in a number of research settings. It comprises three
194
+ subscales and includes one global question: How would
195
+ you describe your quality of life during the past week?
196
+ Responses range from “extremely poor” to “excellent”
197
+ on a seven-point scale. The psychological symptom
198
+ subscale contains eight symptoms. Respondents are
199
+ asked to indicate the frequency with which they have
200
+ experienced each symptom in the past week on a four-
201
+ point scale, ranging from “not at all” (0) to “very much”
202
+ (3). Possible scores on this scale therefore range from 0 to
203
+ 24. The physical symptom subscale contains 22 symptoms;
204
+ scores on this scale range from 0 to 66. The third subscale
205
+ assesses whether respondents are able to perform eight
206
+ activities, given their condition in the past week. Responses
207
+ range from “unable” (0) to “without help” (3), and the
208
+ possible range of scores on this subscale is from 0 to 24
209
+ with lower scores representing better levels of functioning.
210
+ The reliability of this scale has been reported to range from
211
+ 0.68 to 0.90 for physical and psychological distress and
212
+ from 0.42 to 0.89 for the activity subscale.[20]
213
+ Treatment-related symptoms were assessed using the
214
+ European Organization for the Research and Treatment of
215
+ Cancer—Quality of Life (EORTC QoL C30 questionnaire,
216
+ version 1).[21] Though this 30-item questionnaire provides
217
+ a measure on the dimensions of global health status,
218
+ physical role, emotional, cognitive, social functioning, and
219
+ cancer-related symptomatology, we report results of only
220
+ cancer-related symptomatology. Assessments were carried
221
+ out before and after radiotherapy treatment.
222
+ Interventions
223
+ The intervention group received the integrated yoga program
224
+ and the control group received brief supportive therapy
225
+ intervention, each imparted as a one-to-one session with
226
+ the therapist. The yoga intervention consisted of a set of
227
+ asanas (postures done with awareness), breathing exercises,
228
+ pranayama (voluntarily regulated nostril breathing),
229
+ meditation, and yogic relaxation techniques with imagery
230
+ (mind–sound resonance technique and cyclic meditation).
231
+ These practices were based on principles of attention
232
+ diversion, mindful awareness, and relaxation to cope with
233
+ day-to-day stressful experiences. Participants were required
234
+ to attend a minimum of at least three in-person sessions/week
235
+ for 6 weeks during their adjuvant radiotherapy treatment
236
+ in the hospital with self-practice as homework on the
237
+ remaining days. Each of these sessions lasted 1 h and was
238
+ administered by a trained yoga therapist either before or after
239
+ radiotherapy. These sessions started with a few easy yoga
240
+ postures, breathing exercises, and pranayama (voluntarily
241
+ regulated nostril breathing), and yogic relaxation. After this
242
+ preparatory practice for about 20
243
+ min, the subjects were
244
+ guided through any one of the meditation practices for the
245
+ next 30
246
+ min, which included focusing awareness on sounds
247
+ and chants from Vedic texts,[22] or breath awareness and
248
+ impulses of touch emanating from palms and fingers while
249
+ practicing yogic mudras, or a dynamic form of meditation
250
+ that involved practicing, with eyes closed, of four yoga
251
+ postures interspersed with relaxation while supine, thus
252
+ achieving a combination of both “stimulating” and “calming”
253
+ practices.[23] The control intervention consisted of brief
254
+ supportive therapy with education as a component that is
255
+ routinely offered to patients as a part of their care in this
256
+ center. We chose to have this as a control intervention mainly
257
+ to control for the nonspecific effects of the yoga program that
258
+ may be associated with factors such as attention, support,
259
+ and a sense of control as described in our earlier study.[24]
260
+ Subjects and their caretakers underwent counseling by a
261
+ trained social worker (once in 10 days, 15-min sessions)
262
+ during their hospital visits for adjuvant radiotherapy. The
263
+ control group received 3-4 such counseling sessions during
264
+ a 6-week period, where as the intervention group received

+ measure (study dropouts). Pearson’s correlation analyses
304
+ were used to study the bivariate relationships between
305
+ quality-of-life domains and treatment related symptoms.
306
+ RESULTS
307
+ A total of 74 participants (yoga, n = 40; control, n = 34)
308
+ completed the prescribed radiotherapy regimen. All
309
+ participants were ambulatory and had a Zubrod’s
310
+ performance status score of 0-2. All patients had
311
+ mastectomy as primary treatment; 16 subjects received
312
+ radiotherapy following mastectomy and 57 subjects
313
+ received radiotherapy following mastectomy and three
314
+ cycles of chemotherapy. Participants in both groups were
315
+ comparable with respect to sociodemographic and medical
316
+ characteristics [Table 1].
317
+ Psychological distress
318
+ A repeated-measures analysis of variance was done on
319
+ psychological distress scores. Results showed significant
320
+ group-by-time interaction effects [F (1, 72) = 7.64,
321
+ P = 0.01] and between-subject effects [F (1, 72) = 7.91,
322
+ P = 0.01]. Post-hoc tests using Bonferroni’s correction
323
+ showed significant differences between yoga and control
324
+ groups in post-RT measures alone (mean difference ± SE,
325
+ 3.72±1.07; P = 0.001). There was a significant within-
326
+ subjects difference (post- and pre-RT measure) in the yoga
327
+ group alone (mean difference ± SE, 2.95±0.66; P < 0.001;
328
+ 95% CI 1.6-4.3) but not in the control group (0.26±0.71;
329
+ P = 0.71; 95% CI−1.1 to 1.6) [Table 2]. Intention-to-treat
330
+ analysis on the initially randomized sample showed
331
+ significant improvement in psychological distress between
332
+ groups following intervention (−3.47±0.73, P < 0.001,
333
+ −4.91 to −2.03) [Table 3].

601
+ Physical distress
602
+ A repeated-measures analysis of variance was done
603
+ on physical distress scores. There was no significant
604
+ group- by- time interaction effect [F (1, 72) = 3.86, P = 0.05]
605
+ or between-subjects effect [F (1, 72) = 1.49, P = 0.23]. Post-
606
+ hoc tests using Bonferroni’s corrections also did not show
607
+ significant differences between yoga and control groups in
608
+ post-RT measures (mean difference ± SE, −3.31 ± 1 .77;
609
+ P = 0.07). But there was a significant within-subjects
610
+ difference (post- and pre-RT measure) in the yoga group alone
611
+ (mean difference ± SE, 3.20 ± 1.04; P < 0.01, 95% CI 1.1-
612
+ 5.2) but not in the control group (0.18 ± 1.13, P = 0.88, -2.0
613
+ to 2.4) [Table 2]. Intention-to-treat analysis on the initially
614
+ randomized sample showed significant improvement in
615
+ physical distress between groups following intervention
616
+ (−4.18 ± 1.74, P = 0.02, −7.65 to −0.72) [Table 3].
617
+ Activity level
618
+ A repeated-measures analysis of variance was done on
619
+ activity level scores. There was no significant group-by-
620
+ time interaction effect [F (1, 72) = 1.82, P = 0.18] but
621
+ a significant between-subjects effect [F (1, 72) = 5.31,
622
+ P = 0.02]. Post-hoc tests using Bonferroni’s corrections
623
+ showed significant differences between yoga and control
624
+ groups in post-RT measures alone (mean difference ±
625
+ SE, 3.65 ± 1.37; P = 0.01). There was no significant
626
+ within-subjects effect in yoga or control groups following
627
+ intervention [Table 2]. Intention-to-treat analysis did
628
+ not show any significant changes between groups in the
629
+ activity level [Table 3].

635
+ insomnia [F (1, 72) = 16.24, P = 0.001] and appetite loss
636
+ [F (1, 72) = 10.41, P = 0.002] and significant between-

+ subjects effects for fatigue [F (1, 72) = 8.26, P = 0.01] but
638
+ not for insomnia [F (1, 72) = 0.02, P = 0.90] and appetite
639
+ loss [F (1, 72) = 2.72, P = 0.10]. Post-hoc tests using
640
+ Bonferroni’s correction showed significant differences
641
+ between yoga and control groups in post-RT measures
642
+ alone for fatigue (mean difference ± SE, −20.72±5.36;
643
+ P = 0.001), insomnia (−14.31 ± 6.83, P = 0.04), and
644
+ appetite loss (−17.95 ± 5.67, P = 0.002). There was a
645
+ significant decrease in fatigue (mean difference ± SE, 13.39
646
+ ± 3.61; P < 0.001; 95% CI 6.2-20.5) and insomnia (26.02
647
+ ± 4.49; P < 0.001; 17.0-34.9) in the yoga group alone;
648
+ there was a significant increase in loss of appetite in the
649
+ control group (−13.19 ± 4.54, P = 0.005, −22.2 to −4.1)
650
+ [Table 2]. Intention-to-treat analysis on the initially
651
+ randomized sample showed significant improvement in
652
+ fatigue (−17.26 ± 4.89, P = 0.001, −26.99 to −7.53), pain
653
+ (16-.93 ± 6.09, P = 0.007, −29.05 to −4.82), insomnia
654
+ (−13.49 ± 6.60, P = 0.04, -26.60 to −0.38), and appetite
655
+ loss (−14.07 ± 5.46, P = 0.01, −24.93 to −3.22) between
656
+ groups following intervention [Table 3]. Other symptoms
657
+ such as pain, dyspnea, nausea and vomiting, diarrhea, and
658
+ constipation did not change significantly with time in both
659
+ groups, and only pain showed significant between-subjects
660
+ effects [F (1, 72) = 5.20, P = 0.03]. Post-hoc tests using
661
+ Bonferroni’s correction showed significant differences
662
+ between yoga and control groups in pain scores in the
663
+ post-RT measure (mean difference ± SE, −18.36 ± 7.04;
664
+ P = 0.01). There was a significant decrease in pain (mean
665
+ difference ± SE, 10.57±4.34; P = 0.02, 95% CI 1.9-19.2)
666
+ and nausea and vomiting (6.50 ± 2.77, P = 0.02, 0.9-12.0)
667
+ in the yoga group alone following intervention [Table 2].
668
+ Intention-to-treat analysis did not show any significant
669
+ changes between groups in nausea and vomiting, dyspnea,
670
+ constipation, and diarrhea [Table 3].
671
+ Bivariate relationships
672
+ Bivariate relationships were determined between the outcome
673
+ measures. There was a significant positive correlation
674
+ between physical and psychological distress and fatigue,
675
+ nausea and vomiting, pain, dyspnea, insomnia, appetite loss,
676
+ and constipation. There was a significant negative correlation
677
+ of activity levels with fatigue, nausea and vomiting, pain,
678
+ dyspnea, insomnia, and appetite loss [Table 4].

805
+ DISCUSSION
806
+ This study evaluated the effects of integrated approach of yoga
807
+ therapy on symptom distress among early-stage breast cancer
808
+ patients undergoing adjuvant radiotherapy. A significant
809
+ reduction was observed in psychological distress, physical
810
+ distress, a significant increase in the activity level on the
811
+ RSCL and a significant reduction in fatigue, pain, insomnia,
812
+ nausea and vomiting on the EORTC QoL symptom subscale
813
+ following yoga intervention as compared to controls.
814
+ These results offer further support for preliminary findings
815
+ that have shown beneficial effects of yoga intervention in
816
+ reducing distressful symptoms such as fatigue, pain, loss of
817
+ appetite, and insomnia and improving mood and quality-
818
+ of-life concerns in cancer patients. Though beneficial
819
+ effects are seen with yoga on symptom management, it
820
+ should be noted that subjects in these studies were in
821
+ various stages of treatment and disease and had varied
822
+ diagnosis contributing to generalizability of findings.[25] In
823
+ our study, the cohort sample were patients with stage II
824
+ and III breast cancer receiving adjuvant therapy and our
825
+ results support benefits of yoga in modulating distressful
826
+ symptoms related to adjuvant radiotherapy. However,
827
+ adherence did not seem to influence the outcome measures
828
+ possibly due to the fact that an improved adherence
829
+ created an “overall floor effect” thereby not influencing the
830
+ outcome measures. The effect size was high (Cohen’s f >3)
831
+ for fatigue, insomnia, psychological distress, and physical
832
+ distress and moderate for pain and activity.
833
+ There was a significant positive correlation between
834
+ symptoms and physical and psychological distress and
835
+ negative correlation between these and activity. The results
836
+ indicate that yoga intervention was helpful in reducing
837
+ these distressing symptoms and that reduction in these
838
+ could have reduced physical and psychological distress and
839
+ improved activity. Patients with cancer often have multiple
840
+ symptoms and symptoms can often cluster together in a
841
+ systematic way whereby treatment of one can influence the
842
+ treatment of other symptoms as well.[26] Though studying
843
+ the effects of intervention on symptom clusters is not
844
+ the main aim of this study, its effects on a multitude of
845
+ symptoms such as pain, fatigue, nausea, insomnia, and
846
+ loss of appetite could have nevertheless contributed to
847
+ improvement in health outcomes. Moreover, most of these
848
+ symptoms persist throughout the course of disease, and
849
+ the effective treatment of these in initial stages is known
850
+ to affect health outcomes later even after the completion of
851
+ treatment.[27] It may be hypothesized that yoga could serve
852
+ to be a prophylactic intervention in the initial stages of
853
+ treatment affecting quality-of-life outcomes in future. This
854
+ is more so important in today’s scenario where efforts are
855
+ being directed at producing new insights into the causes of
856
+ and cures for cancer, rather than managing the symptoms
857
+ due to the disease and their treatment.
858
+ Evidence suggests that pain, fatigue, and depression are
859
+ frequently undertreated. Patients and health care providers
860
+ have reported depression and a persistent lack of energy as
861
+ the aggressiveness of therapy has been increased and/or the
862
+ underlying malignancy has worsened.[6] Cancer symptom
863
+ management would benefit if an integrated intervention
864
+ plan existed for a cluster of symptoms based on a clear
865
+ understanding of which symptoms are likely to cluster,
866
+ when clustering is likely to occur, and how a symptom
867
+ cluster affects patient outcomes at different stages of
868
+ treatment. Most of these symptom clusters are influenced
869
+ by patient’s perception, awareness, education, and mood
870
+ states, and can be explained through various biologic,
871
+ psychological, behavioral, and sociocultural mechanisms
872
+ that constitute a symptom interaction network and symptom
873
+ experience.[28] The experience of multiple simultaneous
874
+ symptoms has a synergistic effect on symptom distress.[29]
875
+ Management of symptoms therefore requires a holistic
876
+ approach that integrates behavioral and mind–body
877
+ strategies; this is more so emphasized in earlier studies
878
+ that have shown several stress reduction and mind–body
879
+ approaches to reduce distressful symptoms and manage
880
+ mood states in cancer patients. The results of our study
881
+ reinforce findings of our earlier study that has shown
882
+ beneficial effects of yoga intervention in managing
883
+ chemotherapy-related nausea and vomiting.[24] This simple
884
+ intervention can be imparted to nurses and cancer care
885
+ givers especially in developing countries where access
886
+ and resources for supportive care rarely exist.
887
+ There are several limitations to our study; one among
888
+ them could be inequality in contact time for interventions.

934
+ However, it should be noted that supportive therapy[30]
935
+ interaction was only used to negate the confounding
936
+ variables such as instructor–patient interaction, education,
937
+ and attention that could have significantly reduced distress
938
+ in these patients.[31] Secondly, it was not possible to mask the
939
+ yoga intervention from the study participants. Blinding in
940
+ yoga studies is a topic of intense discussion in yoga research.
941
+ As yet there has been no perfect method for blinding yoga
942
+ therapy from the participants because of the nature of the
943
+ therapy itself, which involves the patients being asked
944
+ to perform asanas as well as a spiritual component that
945
+ includes the knowledge that they are performing yoga.
946
+ In conclusion, our yoga intervention shows beneficial
947
+ findings in managing cancer-related symptoms in early
948
+ breast cancer patients taking recourse to adjuvant
949
+ radiotherapy. More robust measures to assess individual
950
+ symptoms must be attempted in future studies. Future
951
+ studies should unravel putative mechanisms of action of
952
+ our intervention for each of these symptoms.

22
+ ABSTRACT
23
+ OBJECTIVE: Ice massage (IM) is one of the treatment procedures used in hydrotherapy. Though its
24
+ various physiological/therapeutic effects have been reported, effects of IM of the head and spine on heart
25
+ rate variability (HRV) have not been studied. Thus, this study evaluated the effects of IM of the head and
26
+ spine on HRV in healthy volunteers.
27
+ METHODS: Thirty subjects were randomly divided into 3 sessions: (1) IM, (2) tap water massage (TWM) and
28
+ (3) prone rest (PR). Heart rate (HR) and HRV were assessed before and after each intervention session.
29
+ RESULTS: A significant increase in the mean of the intervals between adjacent QRS complexes or the
30
+ instantaneous HR (RRI), square root of mean of sum of squares of differences between adjacent normal
31
+ to normal (NN) intervals (RMSSD), number of interval differences of successive NN intervals greater
32
+ than 50 milliseconds (NN50), proportion derived by dividing NN50 by total number of NN intervals
33
+ along with significant reduction in HR after IM session; significant increase in RRI along with significant
34
+ reduction in HR after TWM, and a significant increase only in RMSSD after PR were observed. However,
35
+ there was no significant difference between the sessions.
36
+ CONCLUSION: Results of this study suggest that 20 min of IM of the head and spine is effective in
37
+ reducing HR and improving HRV through vagal dominance in healthy volunteers.

41
+ 1 Introduction
42
+ Naturopathy is a drugless system that aims to bring
43
+ harmony in the physical, mental, moral and spiritual planes
44
+ of living
45
+ [1]. It is a distinct type of primary care medicine that
46
+ blends age-old healing traditions with scientific advances and
47
+ current research
48
+ [2]. It consists of hydrotherapy, diet therapy,
49
+ fasting therapy, mud therapy, helio therapy and air therapy
50
+ [1].
51
+ Hydrotherapy is the external/internal use of water in any

77
+ Ice massage (IM) of the head and spine is one of the
78
+ naturopathic treatments used to reduce blood pressure

+ [9].
80
+ Though it is widely used, the precise physiological
81
+ responses have not been fully explored and, to the best of
82
+ our knowledge, no study has reported the effect of IM of
83
+ the head and spine on heart rate variability (HRV). Thus,
84
+ the present study evaluates the effect of IM of the head
85
+ and spine on HRV in healthy volunteers.
86
+ 2 Materials and methods
87
+ 2.1 Subjects
88
+ A total of 30 healthy male volunteers between 18 and
89
+ 25 years of age were recruited from a residential college
90
+ in south India based on the inclusion criteria.
91
+ 2.1.1 Inclusion criteria
92
+ The criteria for inclusion of patients in the present
93
+ study were: aged 18 years and above, male, and willing to
94
+ participate in the study.
95
+ 2.1.2 Exclusion criteria
96
+ Subjects were excluded if they had a history of any
97
+ systemic and/or mental illness, regular use of any
98
+ medications, regular smoking and/or regular alcohol
99
+ consumption.
100
+ The study protocol was approved by the institutional
101
+ ethics committee of Sri Dharmasthala Manjunatheshwara
102
+ College of Naturopathy and Yogic Sciences and a written
103
+ informed consent was obtained from each subject.
104
+ 2.2 Study design
105
+ A cross over design was used, in which
106
+ each
107
+ participant was assessed in three different intervention
108
+ sessions: (1) IM, (2) tap water massage (TWM) and
109
+ (3) prone rest (PR). Subjects were assigned to treatment
110
+ order randomly by drawing from an envelope with the
111
+ description of the three different orders (n=10)
112
+ [10]. The
113
+ sessions were performed on days 1, 2 and 3 respectively
114
+ in orders: IM, TWM, PR (the first order); TWM, PR, IM
115
+ (the second order); or PR, IM, TWM (the third order).
116
+ Assessments of heart rate (HR) and HRV were measured
117
+ before or after 20 min of each intervention session. The
118
+ trial profile is shown in Figure 1.
119
+ 2.3 Intervention
120
+ Each subject received 3 intervention sessions in any
121
+ one of the 3 different orders as described in the above.
122
+ The duration of each intervention session was about
123
+ 20 min
124
+ [5,11–13]. Duration of the intervention was chosen
125
+ based on a previous study
126
+ [14].
127
+ 2.3.1 IM session
128
+ Subjects were asked to lie prone on the massage table.
129
+ Then, IM was given to the head and spine by continuous
130
+ longitudinal displacements
131
+ [7] by means of a rubber bag
132
+ filled with ice
133
+ [15] (1–2
134
+ oC) for the duration of 20 min
135
+ [5,11–13].
136
+ The use of an ice bag was mainly to avoid overuse injuries
137
+ among the patients
138
+ [6].
139
+ 2.3.2 TWM session
140
+ TWM was given as an active control for IM. Subjects
141
+ were asked to lie prone on a massage table. Then
142
+ TWM was given to the head and spine by continuous
143
+ longitudinal displacements by means of a rubber bag filled
144
+ with tap water (24–25
145
+ oC) for the duration of 20 min.
146
+ 2.3.3 PR session
147
+ PR was given as a passive control, in which subjects did
148
+ not receive any hydrotherapic intervention, but similar to
149
+ IM and TWM, all subjects were asked to lie in the prone
150
+ position for 20 min. The prone rest was given to avoid
151
+ postural variation.
152
+ 2.4 Assessments
153
+ 2.4.1 Anthropometrics
154
+ Height (cm) was measured using a standard measuring
155
+ tape
156
+ [4]. Weight (kg) and body mass index (BMI, kg/m
157
+ 2) were
158
+ measured using Body Composition Analyzer (TANITA
159
+ SC-330, Japan), which calculates body composition from
160
+ bio-electric impedance, and measured by the unit
161
+ [16]. The
162
+ measurement was done by asking the subjects to stand erect
163
+ with bare feet on the footplate of the analyzer.
164
+ 2.4.2 HR and HRV
165
+ HR and HRV were assessed using a four-channel
166
+ polygraph
167
+ (MP 36, Biopac Student Lab, BIOPAC System
168
+ Inc, USA). The Ag/AgCl pre-gelled electrodes were
169
+ placed according to the standard limb lead II configuration
170
+ for recording electrocardiogram. Data were acquired at
171
+ the sampling rate of 1 024 Hz.
172
+ 2.4.3 Data extraction
173
+ Frequency domain and time domain analysis of
174
+ the HRV data were carried out for baseline and post-
175
+ intervention (5 min recordings for each) for each of
176
+ the three intervention sessions. The data recorded were
177
+ visually inspected off-line and only noise-free data
178
+ were included for the analysis
179
+ [17].
180
+ The data were analyzed with an HRV analysis program
181
+ developed by the Biomedical Signal Analysis Group
182
+ (University of Kuopio, Finland)
183
+ [18]. The energy in the
184
+ HRV series in the following specific frequency bands
185
+ was studied: low frequency (LF) band (0.05–0.15 Hz),
186
+ and high frequency (HF) band (0.15–0.5 Hz). LF/HF
187
+ ratio was also calculated. The LF and HF band values
188
+ were expressed as normalized units. The following
189
+ components of the time domain HRV were analyzed:
190
+ (1) the mean of the intervals between adjacent QRS
191
+ complexes or the instantaneous HR (RRI), (2) HR,
192
+ (3) the square root of the mean of the sum of the
193
+ squares of differences between adjacent normal to

198
+ normal (NN) intervals (RMSSD), (4) the number of
199
+ interval differences of successive NN intervals greater
200
+ than 50 milliseconds (NN50) and (5) the proportion
201
+ derived by dividing NN50 by the total number of NN
202
+ intervals (pNN50)
203
+ [17].
204
+ 2.5 Statistical analysis
205
+ Statistical analysis was performed using Statistical
206
+ Package for the Social Sciences (SPSS for Windows,
207
+ Version 16.0, SPSS Inc., Chicago, IL). Analysis of variance
208
+ for repeated measures, followed by post-hoc analysis with
209
+ Bonferroni adjustment for multiple comparisons, was
210
+ performed for testing patients’ responses. A P value < 0.05
211
+ was considered to be significant.
212
+ 3 Results
213
+ 3.1 Demographic variables
214
+ Thirty subjects were assigned into 3 intervention
215
+ sessions on 3 different days. Baseline and post-ntervention
216
+ assessments of each session were made before and after
217
+ the respective intervention session. Of 30 subjects’
218
+ data, there were movement artefacts in the data of 5
219
+ subjects [IM session (n=2), TWM session (n=1), PR
220
+ session (n=2)]; thus these data were not included in the
221
+ statistical analysis. Demographic variables of the study
222
+ subjects were shown in Table 1. There was no significant
223
+ difference among the sessions in baseline assessment in
224
+ any of the variables (Table 2).

240
+ Result of this present study showed significant increases
241
+ in RRI, RMSSD, NN50, pNN50 along with significant
242
+ reduction in HR after IM. Significant increase in RRI
243
+ along with significant reduction in HR after TWM; and a
244
+ significant increase only in RMSSD after PR. However, there
245
+ were no significant differences among the sessions (Table 2).
246
+ 4 Discussion
247
+ Though the results of this present study showed no
248
+ change in the frequency domains such as LF, HF, and
249
+ LF/HF values after all the three intervention sessions,
250
+ significant increases in RRI, RMSSD, NN50 and pNN50,
251
+ along with significant reduction in HR, were observed
252
+ after IM session. This showed that 20 min of IM of the
253
+ head and spine reduced HR and improved HRV towards
254
+ parasympathetic dominance or sympathetic withdrawal.

+ All values are presented as mean ± standard deviation and analyzed using repeated measures of analysis of variance and post-hoc
363
+ analysis with Bonferroni correction. P values are results of within-session analysis. IM: ice massage; TWM: tap water massage;
364
+ RRI: the intervals between adjacent QRS complexes or the instantaneous HR; HR: heart rate; RMSSD: the square root of the mean
365
+ of the sum of the squares of differences between adjacent NN intervals; NN50: the number of interval differences of successive NN
366
+ intervals greater than 50 milliseconds; pNN50: proportion derived by dividing NN50 by the total number of NN intervals; LF: low
367
+ frequency; HF: high frequency.
368
+ The time domain measures of the HRV, i.e., mean RRI,
369
+ RMSSD and NN50 have been recognized as stronger
370
+ predictors of vagal modulation than frequency domain
371
+ measures
372
+ [18]. Thus, the increases in RRI, RMSSD, NN50,
373
+ pNN50 following IM are suggestive of vagal dominance.
374
+ Generally, it is thought that the LF power of the
375
+ HRV corresponds to the cardiac sympathetic activity;
376
+ conversely, HF power corresponds to the cardiac
377
+ parasympathetic activity. However, there is still some
378
+ debate over this matter. It has been reported that neither
379
+ the LF power band nor the HF power band is exclusive
380
+ indices of cardiac sympathetic and parasympathetic
381
+ tone, respectively. The LF power was reduced after
382
+ selective cardiac parasympathectomy, but did not totally
383
+ disappear after a β-adrenoceptor blockage, resulting from
384
+ denervation. Further, the sympathetic activity can also
385
+ influence the HF power but to a lesser extent than the
386
+ effect of parasympathetic activity on the LF power
387
+ [17,18].
388
+ A previous study that focused on three types of cold
389
+ stimulation treatments included: (1) immersing the hand/
390
+ foot in ice water, (2) ice application to forehead and (3) ice
391
+ application to face. This study found that HR and blood
392
+ pressure increased only in the case of hand immersion.
393
+ However, ice application to the forehead or face produced
394
+ an insignificant reduction in HR, as well as insignificant
395
+ changes in blood pressure. This finding indicated that the
396
+ application of ice to the forehead and face might have
397
+ an effect on reducing HR, while to hand/foot had the
398
+ opposite effect
399
+ [19]. Another study on ice bag application to
400
+ the head and spine showed a significant reduction in pulse
401
+ rate and blood pressure, which supports the results of our
402
+ study
403
+ [9].
404
+ A significant increase in RRI coupled with a significant
405
+ reduction in HR, following TWM, indicated that 20 min
406
+ of TWM to the head and spine affected HR and HRV.
407
+ Since within-session analysis of IM of the head and spine
408
+ showed improvement in all the time-domain variables
409
+ of HRV spectra and a significant reduction in HR, it
410
+ may be considered as influencing the HRV towards
411
+ vagal dominance, which is unlike TWM and PR. This
412
+ effect might be used for the prevention and treatment of
413
+ cardiovascular diseases, including hypertension and its
414
+ related problems.
415
+ 5 Strength of the study
416
+ To the best of our knowledge this is the first study
417
+ evaluating the effect of IM of the head and spine on HRV
418
+ in healthy volunteers. A previous study reported that ice
419
+ used in IM treatment should weigh at least 0.6 kg for
420
+ www.jcimjournal.com/jim
421
+ July 2016, Vol 14, No.4
422
+ 310
423
+ Journal of Integrative Medicine
424
+ cold treatment
425
+ [11]. In this study, we used approximately
426
+ 0.6–0.8 kg for IM, resulting in no adverse side effect,
427
+ such as the cold-induced burn or discomfort. Hence, this
428
+ study reports a simple, low-cost intervention that can be
429
+ given by anyone.
430
+ 6 Limitations of the study
431
+ This study was conducted in the healthy male
432
+ volunteers, limiting the application of our findings
433
+ to females and pathological conditions. Investigators
434
+ were not blinded for the intervention sessions.
435
+ Although clinicians were aware of the treatments they
436
+ delivered, all assessments were performed with standard
437
+ equipment. Additional assessments, such as continuous
438
+ blood pressure monitoring, baroreceptor sensitivity,
439
+ photo plethysmography and galvanic skin resistance
440
+ would have given better understanding of the state of the
441
+ autonomic nervous system. The present study assessed
442
+ only the immediate effects of IM, PR and TWM of the
443
+ head and spine on HRV, but did not assess its long-
444
+ term effects or its underlying mechanisms. Hence,
445
+ further studies are required (i.e., randomized control
446
+ trials) engaging a larger sample size, using advanced
447
+ techniques and taking place over a greater period of
448
+ time, in order to evaluate its precise physiological effects
449
+ and underlying mechanisms.
450
+ 7 Conclusion
451
+ Results of this study suggest that 20 min of IM of
452
+ the head and spine is effective at reducing HR and in
453
+ improving HRV towards vagal dominance in healthy
454
+ volunteers.

11
+ Dear Editor,
12
+ Recreational music-making (RMM) was evaluated as a stress-
13
+ alleviating strategy in Japanese corporate male employ-
14
+ ees and was compared to leisure reading as a control [1].
15
+ Following a single session of RMM, the volunteers showed
16
+ enhanced mood, lower gene expression levels of the stress-
17
+ induced cytokine interleukin-10, and higher natural killer
18
+ (NK) cell activity. The increase in NK cell activity was espe-
19
+ cially seen in individuals who had low levels prior to inte-
20
+ rvention. These changes were attributed to the stress-alle-
21
+ viating effects of RMM.
22
+ It was interesting to note that the benefi
23
+ ts were noted after
24
+ a single session of RMM. Similarly, practicing yoga has also
25
+ been shown to reduce subjectively rated occupational stress
26
+ levels as well as psychophysiological signs of stress following
27
+ a short, two-day training program [2].
28
+ A randomized controlled trial assessed the effect of a yoga
29
+ program on NK cell counts in breast cancer patients un-
30
+ dergoing conventional cancer treatment (i.e., surgery fol-
31
+ lowed by radiotherapy and chemotherapy). The study had
32
+ the approval of the institutional review board and the pa-
33
+ tients gave their consent to participate in the trial. Thirty-
34
+ seven women with recently diagnosed stage II and III
35
+ operable breast cancer were randomized to receive yoga
36
+ (n=16; mean age ±S.D, 47.0±7.6 years) or supportive thera-
37
+ py (n=21; mean age ±S.D, 49.8±12.9 years) before primary
38
+ surgery. None of them had any secondary malignancy, re-
39
+ cent infections, or other medical conditions which would
40
+ have infl
41
+ uenced the outcome of the interventions or the as-
42
+ sessments. The age (±1 year), stage of disease, grade, and
43
+ lymph node status were similar in the yoga and supportive
44
+ therapy (control) groups.
45
+ Blood samples were collected between 8 a.m. and 12 p.m.
46
+ to reduce diurnal variation. A baseline assessment was done
47
+ prior to surgery. Follow-up assessments were done at 4 we-
48
+ eks following the baseline assessment (i.e., after surgery),
49
+ 10 weeks from baseline (i.e., after radiotherapy), and 32
50
+ weeks from baseline (i.e., after 6 cycles of chemothera-
51
+ py). Peripheral blood lymphocytes were characterized for
52
+ NK cell subsets using immunohistochemistry (Alkaline
53
+ Phosphatase Anti-Alkaline Phosphatase technique). The
54
+ cells were counted per two hundred fi
55
+ elds and the mean
56
+ percentage of CD56 positive cells per hundred fi
57
+ elds was
58
+ extrapolated.
59
+ The yoga group received a program which included dif-
60
+ ferent yoga techniques while the control group received
61
+ supportive counseling sessions. The yoga program consi-
62
+ sted of postures practiced with awareness (asanas, for 15
63
+ minutes), voluntarily regulated yoga breathing (pranayama,
64
+ for 15 minutes), and relaxation while supine (shavasana or
65
+ the corpse posture) combined with imagery (30 minutes).
66
+ The supportive counseling sessions increased the patients’
67
+ knowledge about the disease and treatment options, there-
68
+ by reducing their apprehensions and anxiety. The patients
69
+ had four yoga sessions in the period before and after surge-
70
+ ry and had three yoga sessions per week during their adju-
71
+ vant radiotherapy treatment with self-practice at home on
72
+ the remaining days. During chemotherapy, patients had
73
+ a yoga session on the same day as chemotherapy, which
74
+ was once in twenty-one days and had an additional yoga
75
+ session once in ten days. The instructor monitored their
76
+ practice at home everyday by telephone calls and house
77
+ visits. Participants were also requested to maintain a da-
78
+ ily diary listing the yoga practices done, duration of prac-
79
+ tice, experience of distressful symptoms, intake of medi-
80
+ cation and their diet. The control intervention consisted
81
+ of brief supportive therapy with education that is routine-
82
+ ly offered to patients as a part of their care in the center.
83
+ This control intervention was chosen to control for fac-
84
+ tors such as attention and support from contact with the
85
+ instructor. Patients and their relatives underwent counse-
86
+ ling by a trained social worker once in 10 days, as 15 mi-
87
+ nute sessions during their hospital visits for adjuvant ra-
88
+ diotherapy and chemotherapy. Patients in the supportive
89
+ therapy group also completed daily diaries on treatment
90
+ related symptoms, medication and their diet during che-
91
+ motherapy. Data were analyzed using a repeated measures

108
+ In contrast, the NK cell percentage did not signifi
109
+ can-
110
+ tly decrease in the yoga group, at corresponding time po-
111
+ ints [i.e., baseline/pre-surgery (20.1±6.5) to post-surgery
112
+ (19.8±5.8); and from pre-surgery (20.1±6.5) to post-chemo-
113
+ therapy (16.9±3.2)]. The NK cell percentage was higher in
114

115
+ the control group (13.8±3.2; p<0.05). However, there were
116

117

119
+ These fi
120
+ ndings are consistent with those of other, non-yoga
121
+ stress reduction interventions [3]. Also, an earlier study sho-
122
+ wed an increase in NK cell counts after 24 weeks of yoga
123
+ voluntarily regulated rhythmic breathing (sudarashan kriya
124
+ yoga and pranayama) in patients with cancer [4].
125
+ Decrements in NK cell counts have been found to be an
126
+ important predictor for survival in advanced breast cancer
127
+ patients. The present results suggest that practicing yoga
128
+ helped to reduce immune suppression associated with che-
129
+ motherapy in early breast cancer patients. Catecholamines
130
+ and glucocorticoids have been shown to rapidly and marke-
131
+ dly affect the dynamics and distribution of NK cells in the
132
+ spleen. liver, lungs, circulating blood, and marginating pool
133
+ of blood [5,6]. It may be hypothesized that changes in these
134
+ hormone levels following yoga [7], could be one of the ways
135
+ in which yoga practice infl
136
+ uences NK cell levels.

+ Abstract
17
+ The aim of the study was to test the efficacy of a one month in-patient naturopathy and yoga programme
18
+ for patients with asthma. Retrospective data of 159 bronchial asthma patients, undergoing the naturopathy
19
+ and yoga programme, was analyzed for Forced Vital Capacity, Forced Expiratory Volume at the end of 1
20
+ second, Maximum Voluntary Ventilation and Peak Expiratory Flow Rate on admission, 11th day, on discharge
21
+ and once in three months for three years. The paired sample t test results showed significant increase in
22
+ the Forced Vital Capacity and Forced Expiratory Volume from the date of admission up to 6th month
23
+ (P<0.0035) post Bonferroni correction. Maximum Voluntary Ventilation significantly increased from admission
24
+ till the date of discharge (P<0.0035) and Peak Expiratory Flow Rate significantly increased from admission
25
+ till the 36th month of follow-up (P<0.0035), post Bonferroni correction. This validated the beneficial effect of
26
+ combining naturopathy and yoga for the management of bronchial asthma.

+ Introduction
29
+ Research has shown that different types of alternative
30
+ and complementary treatments like acupuncture,
31
+ yoga, tai chi, chuan and hypnosis have been used
32
+ by asthma patients in alleviating their symptoms (1).
33
+ A meta-analytical review of seven databases including
34
+ three RCTs and one NRCT suggested that yoga lead
35
+ to significant greater reduction in airway hyper-
36
+ response, PC20 (needed to provoke a 20% reduction
37
+ in forced expiratory volume in the first-second weekly
38
+ number of asthma attacks), and the need for drug
39
+ treatment (2). Other reviews have also reported that
40
+ yoga leads to a significant greater reduction in airway
41
+ hyper-response, weekly number of asthma attacks
42
+ and drug treatment (3-7).
43
+ In the last decade, there have been only 12
44
+ experimental studies in the field of yoga and asthma
45
+ (8-17). As yoga is a long-term treatment - with its
46
+ efficacy most pronounced after 4-8 weeks, it is very

60
+ These patients were not controlled satisfactorily by
61
+ conventional medicines prior to their enrollment into
62
+ the study. Patients with other major health problems
63
+ (medical/neurological/psychiatric) were excluded from
64
+ the study. Before enrolling in the study all the
65
+ patients were using conventional medicines as
66
+ prescribed by their physician. As these patients were
67
+ treated by different physicians who were not a part
68
+ of the current study, the researchers had no control
69
+ on the method of treatment used prior to their
70
+ enrollment in the study. Hence at the start of study
71
+ each patient was examined by the investigator/
72
+ naturopath physician. Based on the patient’s disease
73
+ condition the investigator prescribed the minimum
74
+ pharmacological intervention/medication dosage to
75
+ help control the symptoms.
76
+ The combined intervention of Naturopathy and Yoga
77
+ was provided as a residential treatment for a period
78
+ of one month at Jindal Nature Cure Hospital. The
79
+ Yoga session included physical activity, relaxation,
80
+ regulated breathing and philosophical aspects of
81
+ yoga. The Integrated yoga module was selected from
82
+ the integrated set of yoga practices used in earlier
83
+ studies on yoga for positive health (18). The yoga
84
+ sessions were conducted three times in a day.
85
+ Morning sessions of asanas were conducted for about
86
+ one hour. It consisted of ‘suryanamaskar’ of 4 rounds
87
+ and other asanas such as Ardha cakräsana,
88
+ Pädahastäsana, Vajräsana, Supta vajräsana, Ardha
89
+ matsendrsana, Paschimottasana, Ustrasana,
90
+ Naukasana, Shashanasana, Halàsana or Mayüräsana,
91
+ Dhanuräsana, Sarvängäsana, Matyäsana, Ardha
92
+ sirsasana or sirsasana, Vipareetakarani (one round
93
+ of each asana). Beside this ‘yogic kriyas’ such as
94
+ Jalaneti, Gargling, Ghee drop in nose, Vamana
95
+ dhuti (once in three days), Rubber neti, Trataka,
96
+ Kapälabhäti, Laughing Exercises – were practiced
97
+ for half an hour. The afternoon session consisted of
98
+ half an hour of yoga asanas (as listed above) which
99
+ included one round of each asana. The evening
100
+ session consisted of half an hour of ‘yoga nidra’. All
101
+ sessions were done under supervision – in the
102
+ presence of a qualified yoga instructor, specially
103
+ trained for the study protocol.
104
+ essential to have extended follow-up studies to test
105
+ the efficacy of yoga for treatment of asthma. In the
106
+ last few decades, only one long-term follow-up study
107
+ (3-54 months follow-up) has been conducted to
108
+ assess the effect of a 2 week integrated yoga therapy
109
+ programme on patients suffering from asthma (18).
110
+ This study showed that there was a significant
111
+ improvement in the yoga group in the weekly number
112
+ of attacks of asthma, scores for drug treatment, and
113
+ peak flow rate (18).
114
+ Along with the mind-body therapy of yoga that
115
+ integrates physical postures, breathing exercises,
116
+ and meditation, the researchers of the current study
117
+ believe that the intake of naturopathic medicine
118
+ [natural substances to treat the patient (19)] can
119
+ create a lasting effect in the patient‘s mental,
120
+ emotional, and physical states. Till date only one
121
+ self controlled matched study has looked at the
122
+ efficacy of a 21 day naturopathy and yoga intervention
123
+ in bronchial asthma and has shown significant
124
+ improvement in PEFR, VC, FVC, FEV1, FEV/FEC%,
125
+ MVV, ESR and absolute Eosinophil count (11). We
126
+ have thus attempted to analyze retrospective data of
127
+ a study which was designed to test the efficacy of
128
+ a combined treatment of naturopathy and yoga
129
+ treatment in patients with asthma, using a
130
+ longitudinal follow-up design (36 month follow-up
131
+ design).
132
+ Methods
133
+ The current study was a retrospective study and
134
+ hence all cases available of bronchial asthma in the
135
+ INYS Medical Research Society – Jindal Nature Cure
136
+ database and meeting the eligibility criteria were
137
+ selected [n=159 patients (74 males and 85 females)].
138
+ The average age of these patients ranged from 18 to
139
+ 70 years [mean age (SD): 39.8 (13.0) years] and
140
+ their average education was tenth standard. The
141
+ average (SD) duration of untreated illness (asthma)
142
+ was 10(8.01) months. 71% of patients had a family
143
+ history of asthma.
144
+ In the original study, diagnosis of asthma was arrived
145
+ at based on the: (1) detailed medical history, (2)
146
+ physical examination including auscultation, (3)
147
+ spirometry measures (to demonstrate obstruction and
148
+ 234
149
+ Rao, Kadam, Jagannathan, Babina, Rao and Nagendra
150
+ Indian J Physiol Pharmacol 2014; 58(3)
151
+ Naturopathy therapies were selected as per the
152
+ standard practice/treatment prescribed for patients
153
+ with asthma. The treatment included various
154
+ combinations of naturopathic treatments such as diet,
155
+ mud pack, enema, steam bath, steam inhalation,
156
+ hot-hip bath, contrast foot bath, oxygen bath, hot-
157
+ foot arm bath, drainage massage, oil massage,
158
+ neutral immersion bath, vibro-drainage massage, hot
159
+ check pack, sauna, half bath, neutral spinal bath
160
+ and asthma bath.
161
+ Both men and women were provided the same
162
+ intervention programme. Menopausal patients were
163
+ not excluded from the study. If a woman patient was
164
+ observed to be menstruating during the study period,
165
+ she was barred from practicing therapies which were
166
+ considered contraindicative during the period (like
167
+ abdominal packs and hydrotherapy treatments
168
+ involving abdomen and pelvis and yogic exercises
169
+ contraindicative during menstruation). The remaining
170
+ therapies were continued with these women
171
+ participants.
172
+ The subjects were assessed at baseline, 11th day
173
+ and after 21 days (post naturopathy-yoga
174
+ intervention). The subjects were followed up once in
175
+ every three months for three years. During each
176
+ follow-up visit, the patients were examined by a
177
+ physician and based on the patient’s condition the
178
+ anti asthmatic drugs were first documented and then
179
+ either reduced or stopped. In case of aggravation of
180
+ symptoms after stopping/reduction of pharmacological
181
+ medications inhaled bronchodilators were used as
182
+ rescue medications to manage acute bronchospasm;
183
+ and/or naturopathy therapies (like hot chest pack,
184
+ hot foot immersion) were provided for symptomatic
185
+ relief. In an eventuality of these therapies failing to
186
+ relieve the symptoms, there was a provision in
187
+ protocol to provide symptomatic relief medication (â
188
+ agonist) based on the assessment of a general
189
+ physician.
190
+ The outcome variables assessed were Forced Vital
191
+ Capacity (FVC), Forced Expiratory Volume (FEV1),
192
+ Maximum Voluntary Ventilation (MVV) and Peak
193
+ Expiratory Flow Rate. FVC was the total volume of
194
+ air breathed out by the person after a full inspiration
195
+ (inhalation) into a spirometer. FEV1 was the volume
196
+ of air expired into a spirometer in the first second
197
+ (FEV1). MVV was measured based on how quickly
198
+ one can exhale (MVV) and PEFR was measured as
199
+ the greatest amount of air one can breathe in and
200
+ out during one minute. FVC, MVV were assessed
201
+ using a ‘spirometry’, whereas PEFR was assessed
202
+ using ‘Peal flow meter’.
203
+ The above primary study data was retrospectively
204
+ analyzed in the year 2008-2011, from the medical
205
+ record files of the Jindal Nature Cure Hospital using
206
+ the Statistical Software of Social Sciences (SPSS)
207
+ version 10. The baseline data of the patients was
208
+ assessed using Kolmogorov-Smirnov test for
209
+ normality. As the data normally distributed (P>0.200)
210
+ and the study design did not have a control group,
211
+ paired t test was used to analyze the pre/post data.
212
+ Due to multiple comparisons with baseline, Bonferroni
213
+ correction was also conducted using the formula
214
+ 0.05/n (where n=14, as there were 14 pair wise
215
+ comparisons only with baseline). Though Bonferroni
216
+ correction is usually used with ANOVA, statistical
217
+ experts have opined that in case of multiple baseline
218
+ comparisons with t test, this method could be used
219
+ to increase the power of the test used and to
220
+ determine the significant results (20). The Holm–
221
+ Bonferroni method, a uniformly more powerful test
222
+ procedure (i.e. more powerful regardless of the values
223
+ of the unobservable parameters) was also considered
224
+ as an effective alternative power test. However, as
225
+ current methods for obtaining confidence intervals
226
+ for the Holm-Bonferroni method do not guarantee
227
+ confidence intervals that are contained within those
228
+ obtained using the Bonferroni correction (21), the
229
+ authors of this paper have analyzed the data using
230
+ only Bonferroni correction.
231
+ Results
232
+ Records detailed that as all the patients were under
233
+ direct observation and care of investigator there was
234
+ very good compliance to the interventions during their
235
+ stay in the hospital. Though the patients were advised
236
+ to continue the interventions at home post discharge,
237
+ their compliance to these treatments during the 3
238
+ years of study period was checked but not
239
+ documented. Out of the 159 recruited patients,

644
+ To understand the gender differences, independent
645
+ sample t test analysis was conducted. The results
646
+ depicted that FVC, FEV1, MVV and PEFR were
647
+ significantly lower in men as compared to females
648
+ at the time of discharge (P<0.05, Table III). However
649
+ the same variables were significantly higher in males
650
+ as compared to females at the last follow-up (36th
651
+ month; P<0.05, Table IV).
652
+ on FVC, FEV1, MVV and PEFR, as long as the
653
+ intervention is practiced regularly by the patients. A
654
+ look at Table I shows that all the outcome variables
655
+ have significant results from admission till date of
656
+ discharge (the time period during which the patients
657
+ practiced yoga and naturopathy as in-patients) Due
658
+ to the positive results during admission, it could be
659
+ assumed that the patients continued to practice both
660
+ the interventions at home for the next few months
661
+ (positive results observed in all outcome variables
662
+ till the 6th month). However, even though the patients
663
+ were followed up every three months for two years
664
+ post discharge, the possible lack of motivation to
665
+ continue the interventions at home could be one of
666
+ the reasons for lack of significance in most outcome
667
+ variables post 6 months.
668
+ In case of yoga and naturopathy, it is well known
669
+ that regular practice of the interventions can only
670
+ bring about desired results. However this aspect is
671
+ also true vice-versa, where it is often observed that
672
+ positive results of an intervention are a strong
673
+ indicator for continuation of the treatment. It could
674
+ be reasoned that the lack of motivation to continue
675
+ practice post 6 months could have resulted in
676
+ stagnation in symptoms, which in turn could have
677
+ acted as a disillusionment to continue with the
678
+ treatment itself. This could possibly explain the large
679
+ attrition or drop-out rates in the study.
680
+ In such a scenario, it would be best to discuss the
681
+ results and the effectiveness of the intervention when
682
+ it is practiced regularly. A number of studies have
683
+ shown varied results with respect to FEV and FVC
684
+ as output variables in testing the efficacy of
685
+ interventions for asthma. One such study showed
686
+ that there was no significant difference in pre- and
687
+ post-FEV1 and pre- and post-FVC and in their
688
+ percentage predicted. Thus it was concluded that
689
+ reversibility in FEV1 levels or percentage change in
690
+ FEV1 are promising lab parameter to assess the
691
+ efficacy of intervention in asthma patients (22). In
692
+ another study PEFR and FEV1 improved significantly
693
+ following inhalation of bronchodilator in each of the
694
+ five spacers. Similarly delta FEV1 and percentage
695
+ improvement were comparable in the five groups. This
696
+ study corroborates the results of our study where

797
+ Discussion
798
+ The above results depict that the combined yoga
799
+ and naturopathy intervention has a significant effect
800
+ Indian J Physiol Pharmacol 2014; 58(3)
801
+ Naturopathy and Yoga for Asthma
802
+ 237
803
+ Expiratory Flow Rate) PEFR values have seen
804
+ an increase (improvement) from admission to
805
+ discharge. Only one study till date has looked at
806
+ the Maximal minute ventilation during exercise
807
+ and pulmonary function of 78 elite winter athletes
808
+ (25 males, 53 females; 25 EIB positive, 53 normal)
809
+ retrospectively (23). In such a scenario, our study
810
+ is the first to show the positive relation between
811
+ MVV and improvement in symptoms of asthma
812
+ patients through the use of yoga and naturopathy
813
+ treatment.
814
+ The results of gender comparison depict that though
815
+ males improved better than females at discharge,
816
+ females improved better than males at the end of
817
+ 36th month of the study. According to the treating
818
+ team at INYS-Medical Research Society, Jindal
819
+ Nature cure Institute, Bangalore, the patients were
820
+ banned from using addictive substances (i.e. nicotine)
821
+ during their stay at the hospital, as nicotine had an
822
+ adverse reaction to the asthma symptoms. Though
823
+ not documented, a number of males in the current
824
+ study were addicted to nicotine and the team
825
+ felt that, it was difficult to control the additive/drug
826
+ habits of the patients once they were discharged
827
+ from the hospital. This could be one of the causes
828
+ for the gender differences at different timelines of
829
+ the study.
830
+ This study has some inherent limitations: (1) As a
831
+ retrospective study, it is difficult to interpret the result
832
+ based on the current cultural milieu and patient
833
+ characteristics of the hospital, (2) Due to lack of
834
+ control group, the result could be interpreted as an
835
+ outcome of extraneous factors or time factor (patient
836
+ improving over time) instead of the effectiveness of
837
+ the treatment introduced, (3) As the interventions of
838
+ yoga and naturopathy were provided together, it was
839
+ difficult to tease out the individual effects of each of
840
+ the interventions for asthma. A cross-over design
841
+ could have helped in this purpose. Further, to
842
+ strengthen the overall study methodology, future
843
+ research could focus on conducting a prospective
844
+ randomized control clinical trial based on the GINA
845
+ guidelines (for diagnosis and management of bronchial
846
+ asthma), with a large sample size.
847
+ In spite of the limitations explained above, the current
848
+ study is a classic longitudinal study with a 36 month
849
+ follow-up of patients who have undergone a combined
850
+ naturopathy and yoga intervention. As all patients
851
+ were on conventional care at baseline, practicing the
852
+ combined naturopathy and yoga treatment, clearly
853
+ demonstrated positive and significant changes in lung
854
+ function even after tapering of the antiasthamatic
855
+ medications. The naturopathy treatment helped create
856
+ a lasting effect in the patient‘s mental, emotional,
857
+ and physical states and yoga helped reduce the
858
+ frequency of infections (by enhancing the immunity)
859
+ and mental stress. In this context, the present
860
+ study can have significant clinical implications
861
+ as a new and modern solution for bronchial
862
+ asthma patients who suffer from the other adverse
863
+ effects of consuming oral pharmacological medicines.
864
+ Further propagating naturopathy and yoga as a
865
+ way of life (long term practice of intervention), could
866
+ help not just control symptom exacerbation but
867
+ also improve the overall health and immunity of the
868
+ patient.
869
+ Conclusion
870
+ The current study provides evidence that if practiced
871
+ regularly, a combined intervention of naturopathy and
872
+ yoga is an effective alternative treatment for bronchial
873
+ asthma. A rigorous prospective randomized control
874
+ clinical trial based on the GINA guidelines for
875
+ diagnosis and management of bronchial asthma, with
876
+ a large sample size would help further validate these
877
+ results and also tease out the effects of the individual
878
+ and/or combined treatments.

+ INTRODUCTION
30
+ Spinal Cord Injury (SCI) is a catastrophic event which is sudden
31
+ and unexpected that can affect the patient’s normal sensory, motor
32
+ and autonomic function, leading to dependency, morbidity and
33
+ deterioration in mental health and QOF [1,2]. SCI leads to immense
34
+ economic burden on the country’s health care system [3,4]. The
35
+ true impact of SCI can be reflected through the average prevalence
36
+ rate of 1:1000, and the mean incidence estimated to be between
37
+ 4-9 cases per 100,000 populations per year, worldwide [5]. It was
38
+ also reported that the gender ratio in traumatic SCI is 3:1 (men:
39
+ women), whereas gender is equally distributed in non-traumatic SCI
40
+ [4]. Management of acute TSCI often involves surgery followed by
41
+ long term rehabilitation to improve functional abilities and QoL [6].
42
+ Patients with SCI often experience post-traumatic stress disorder
43
+ and distress which are associated with decrease compliance with
44
+ rehabilitation. Prevalence of other co-morbidities such as emotional
45
+ distress, psychological issues and Post-Traumatic Stress Disorders
46
+ (PTSD) is very high which makes an adjustment to Activities of Daily
47
+ Living (ADL) very poor [7].
48
+ Evidence shows raised CRP in chronic SCI patients even without
49
+ the evidence of any concurrent infections, which is an indicator of
50
+ systemic inflammation and is associated with poor rehabilitation
51
+ outcome [8]. Increased Body Mass Index (BMI) in SCI is associated
52
+ with increased risk of Cardio-Vascular Disease (CVD). BMI has
53
+ been used in earlier studies as a stand-in predictor of risk of
54
+ obesity in individuals with SCI [9,10]. The therapeutic benefit of
55
+ medications is often inadequate in the management of neurological
56
+ and psychiatric disorders [11]. Various other studies have proved
57
+ that yoga, a form of mindbody intervention and Physical Therapy
58
+ (PT) have enhanced recovery in various neuropsychiatric illnesses
59
+ [12]. Yoga enhances motor and sensory function, ADL, gait, mental
60
+ flexibility, psychological well-being and relaxation in individuals with
61
+ SCI [13-15].
62
+ Different yogic techniques incorporated into the rehabilitation
63
+ protocol of individuals with SCI, with proper guided assistance, is
64
+ believed to stimulate neural pathways and neurotransmitters [16].
65
+ This, in turn, can be valuable instrument in the regeneration of nerve
66
+ fibres in SCI patients [17]. However, a large number of studies
67
+ recommended RCTs to assess the impact of yoga in SCI [13,15,18].
68
+ Therefore, authors hypothesised to see the add-on effect of Yoga
69
+ therapy along with Physiotherapy may improve motor and sensory
70
+ scores on ASIA scale, QoL, inflammatory markers, distress and
71
+ functional independence in patients with Spinal Cord Injury, rather
72
+ than Physiotherapy rehabilitation alone in paraplegic patients.
73
+ MATERIALS AND METHODS
74
+ Design
75
+ This was a single-blind pre-post randomised controlled trial where
76
+ all participants were randomly divided into two groups: (i) add-
77
+ on yoga and physiotherapy group (IYP); and (ii) Physiotherapy
78
+ Group (PT). Prior to randomisation each participant was assessed
79
+ at the baseline.
80
+ Participants
81
+ A total of 157 SCI patients who were admitted to the Swami
82
+ Vivekananda National Institute of Rehabilitation, Training and
83
+ Research (SVNIRTAR), Odisha, India, were screened using ASIA
84
+ scale during the period between April 2018 to October 2018. The
85
+ sample size was calculated using G-power software by fixing the
86
+ alpha at 0.05 powered at 0.8 and the effect size of 0.55 based on the

+ ABSTRACT
91
+ Introduction: Traumatic Spinal Cord Injury (SCI) is a leading
92
+ cause of disability. Varying injury level and severity generate a
93
+ spectrum of neurological dysfunction and a reduction in long-
94
+ term Quality of Life (QOL) with a decrease in mobility.
95
+ Aim: To evaluate the add-on effect of a Yoga program along
96
+ with physiotherapy on individuals with paraplegia.
97
+ Materials and Methods: A total of 124 SCI patients of both
98
+ genders with age range 18-60 years, having incomplete SCI
99
+ (AIS)-C and (AIS)-D, and admitted to the rehabilitation centre,
100
+ India, were randomly allocated into two groups i.e.,: (i) Study
101
+ group-Integrated Yoga and Physiotherapy (IYP) (n=62; age
102
+ means and SD: 33.97±10.0 years); and (ii) control group-
103
+ Physiotherapy (PT) (n=62; age mean and SD:32.84±9.5 years).
104
+ These participants were assessed on primary outcome
105
+ measures: (i) American Spinal Injury Association Impairment
106
+ (ASIA) scale; (ii)  c-Reactive Protein (CRP); (iii) Spinal Cord
107
+ Injury Independence Measure (SCIM); and (iv) Medically Based
108
+ Emotional Distress Scale (MEDS). The secondary outcome
109
+ measures were: (i) Body Mass Index (BMI); and (ii) Quality of
110
+ Life Index Spinal Cord Injury - Version III (SCI-QOL index), were
111
+ measured before and after one-month interventions.
112
+ Results: The IYP group showed a significant reduction in
113
+ scores of CRP (p<0.001), SCIM (p<0.001), MEDS (p<0.001),
114
+ and improvement in SCI-QoL Index (p<0.001) compared to the
115
+ control group. There was no significant change observed in the
116
+ ASIA scale between the two groups.
117
+ Conclusion: One-month Integrated Yoga and Physiotherapy
118
+ program is more effective than physiotherapy intervention
119
+ alone, in the management of paraplegia patients.

125
+ practice protocol were safe, feasible and have been adapted for the
126
+ intervention with consent from authors of the previous study [19].
127
+ An attendance register was maintained to monitor the attendance of

130
+ Yoga therapy for IYP group: The specific module of yoga therapy
131

132
+ traditional yoga scriptures (Patanjali Yoga Sutras, Upanishads
133
+ and Yoga Vashishtha) that highlight a holistic approach to health
134
+ management at physical, mental, emotional and intellectual levels.
135
+ The practices consisted of yogic postures (asanas), breathing
136
+ practices (pranayama), cleansing techniques (kriya), relaxation
137
+ techniques, meditation and yogic counselling, chosen specifically for
138
+ SCI. SCI special techniques progressed from safe yogic movements
139
+ to yoga postures that provide traction like effect and channelise the
140
+ vital energy flow all through the spine. The details of yoga therapy

240
+ Primary Outcomes
241
+ American Spinal Injury Association (ASIA) impairment scale:
242
+ The ASIA Impairment Scale is an improvisation of the earlier Frankel
243
+ scale and includes a number of important improvements. The
244
+ International Standards for Neurological Classification of Spinal
245
+ Cord Injury (ISNCSCI) was developed by the ASIA as a universal
246
+ Ethical Clearance
247
+ The study was approved by the Institutional Ethics Committee of
248
+ University (RES/IEC-SVYASA/93/2016). Signed informed consent
249
+ was obtained from the head of the institution and each participant,
250
+ upon explaining the study details. CTRI Registration Number:
251
+ CTRI/2018/07/014779.
252
+ Randomisation
253
+ A Total of 124 participants were assigned in two groups, 62 in each,
254
+ using computer-based random number generator. One hundred
255
+ and twenty-four envelopes were prepared, and each participant
256
+ was asked to pick an envelope. Depending on the number in the
257
+ envelope, participants were considered either in IYP group or in PT
258
+ group {known as Sequentially Numbered Opaque Sealed Envelopes
259
+ (SNOSE) randomisation technique}.
260
+ Intervention
261
+ Participants in the IYP group received 75 minutes (six days/week)
262

267
+ classification tool for SCI, depending upon motor and sensory
268
+ impairment that results from an SCI. In sensory examination, two
269
+ aspects of sensation are examined: light touch and pinprick. A
270
+ grade of 0 denotes absent sensation, 1 denotes impaired or altered
271
+ sensation and 2 denotes normal sensation. The motor examination
272
+ consists of testing key muscle functions. Motor strength is recorded
273
+ for each muscle group bilaterally and is graded using a universal
274
+ six-point scale (graded as 0-5) where 0 denotes total paralysis and
275
+ 5 is normal [20].
276
+ Bio-marker: c-Reactive Protein (CRP) is a blood test marker for
277
+ inflammation in the body [21]. Blood samples from the patients
278
+ were collected early in the morning at 8.00 a.m. for the sake of
279
+ convenience without any other prior instructions of fasting. The
280
+ CRP levels <1.0 mg/dL was denoted as negative and CRP levels
281
+ >1.0 mg/dL was denoted as positive [22].
282
+ Spinal Cord Independence Measure (SCIM): Functional recovery
283
+ may or may not follow/translate into neurologic recovery. SCIM
284
+ III is a sensitive outcome measure designed to assess functional
285
+ status relevant to SCI. It can be used as a scale in traumatic and
286
+ non-traumatic, acute and chronic SCI. There is a total of 19 items
287
+ on the SCIM III, which are divided into three subscales (self-care,
288
+ respiration and sphincter management, and mobility). A total score
289
+ out of 100 is achieved, with the subscales weighted as follows: self-
290
+ care: scored 0-20; respiration and sphincter management: scored
291
+ 0-40; and mobility: scored 0-40. Scores are higher in patients that
292
+ require less assistance or fewer aids to complete basic activities of
293
+ daily living and life support activities. SCIM III has been validated
294
+ with excellent internal consistency (Cronbach’s alpha=0.91),
295
+ excellent inter-rater reliability (r=0.99), and excellent correlation with
296
+ the Functional Independence Measure (FIM) (r=0.85, p<0.01) [23].
297
+ Medical-Based Emotional Distress Scale (MEDS): The MEDS
298
+ is a 60-item (7 subscales) clinician-administered questionnaire that
299
+ is completed following a structured interview to assess emotional
300
+ reactions to severe physical illness or disability that are not the direct
301
+ result of a physical condition or problem. This instrument measures
302
+ distress along seven subscales: Dysphoria (8 items), Irritability
303
+ (9 items), Anhedonia (11 items), Social Withdrawal (9 items),
304
+ Ruminations over past events (6 items), Cognitive Perspective in
305
+ the Present (8 items), and Expectations for the future (9 items). Each
306
+ item provides a question and is followed by a range of responses
307
+ that are on a 5-point scale for either intensity (how much?) or
308
+ frequency (how often?). The questions are organised by subscale
309
+ and the interview is structured such that a denial of problems in a

+ certain area allows the interviewer to skip to the next subscale [24].
311
+ Secondary Outcomes
312
+ Quality of Life Index Spinal Cord Injury-Version III: The ferrans
313
+ and powers quality of life index spinal cord injury-version III is an index
314
+ of 74 items divided into two parts: satisfaction and importance. The
315
+ Ferrans and Powers Quality of Life (QLI) emerged its specific version
316
+ for spinal cord injury, known as QLI Spinal Cord Injury - Version III.
317
+ It was developed by Carol Estwing Ferrans and Powers Marjorie in
318
+ 1984 [25]. The QLI-SCI was developed to measure quality of life
319
+ specifically in people with spinal cord injury. It can be administered
320
+ by interview or by self-report and contains 37 items and each item is
321
+ rated on a scale of 1 (least satisfied/important) to 6 (most satisfied/
322
+ important). Five scores of 0-30 (0=less satisfied, 30=most satisfied)
323
+ are calculated for the following subscales:
324
+
325
+ Total quality of life score
326
+
327
+ Health and functioning subscale
328
+
329
+ Social and economic subscale
330
+
331
+ Psychological/spiritual subscale
332
+
333
+ Family Subscale
334
+ Calculation of score weighs satisfaction scores according to the
335
+ level of importance assigned to each item.
336
+ Anthropometry: Body Mass Index (BMI), The BMI, or Quetelet
337
+ index, is a measure of relative weight based on an individual’s mass
338
+ and height [26]. For measuring the height, the recumbent length of
339
+ the study participants was measured by making them lies supine on
340
+ a raised mat table. With the participant’s head in the Frankfort plane,
341
+ authors placed one metal plate against the top of the participant’s
342
+ head and the ruler along the right side of the participant’s body.
343
+ With the right leg aligned with their hip, the other end of the ruler
344
+ was placed on the distal end of the calcaneus of their right foot.
345
+ If the participant had spasticity, contractures, or could not lay flat
346
+ or dorsiflex the ankle to 90°, authors manually assisted them in
347
+ extending the leg as far as possible or dorsiflexing the ankle. Height
348
+ was then recorded to the nearest 1/16 of an inch [27]. Total weight
349
+ was measured using a Wheelchair (WC) platform scale and the
350
+ participant’s weight was recorded with his/her WC. The participant
351
+ then transferred out of his/her WC and the WC was weighed alone.
352
+ Body weight was calculated by subtracting WC weight from the
353
+ total weight.
354
+ Statistical ANALYSIS
355
+ Data were analysed using the R-Studio. Shapiro-Francia test was
356
+ used to check the normality of data distribution. Gender and other
357
+ categorical variables were analysed using chi-square test. Mc-Nemar
358
+ test was used to analyse within the group differences in categorical
359
+ variables. The independent sample t-test was used for between-
360
+ group analysis and paired samples-test was used for within-group
361
+ change from pre- to post- at Day 1 and Day 30. Pearson’s correlation
362
+ was done between age and outcome measured variables. The level
363
+ of significance considered for the present study was p<0.05.
364
+ RESULTS
365
+ One-hundred-twenty-four paraplegic patients participated in the
366
+ study. The mean age of the participants was 33±10.0 years and
367
+ 32.84±9.5 years in IYP and PT group respectively. The number
368
+ of males and females were almost similar in both the groups.
369
+ The characteristics and socio-demographic information of study
370
+ participants are presented in [Table/Fig-3].
371
+ Within-group Comparisons
372
+ At the completion of one month, the difference between BMI,
373
+ SCI-QOL, SCIM, MEDS, CRP and ASIA score was statistically
374
+ significant in both the groups however the percentage difference
375
+ and the change in the number of participants were more in IYP
376
+ group [Table/Fig-4,5].
377
+ The male participants in IYP (n=54) and in PT (n=53) showed that
378
+ there was a significant change in BMI (p<0.001; p<0.05), SCI-
379
+ QOL Index (p<0.001; p<0.001), SCIM (p<0.001; p<0.001), and
380
+ MEDS (p<0.001; p<0.005) when compared with baseline. Similarly,
381
+ female participants in IYP (n=8) and in PT (n=9) also demonstrated
382
+ significant improvement in BMI (p=0.477; p=0.429), SCI-QOL
383
+ Index (p<0.001; p=0.339), SCIM (p<0.005; p<0.001), and MEDS
384
+ (p<0.001; p<0.005) when compared with baseline [Table/Fig-6a,b].
385
+ Between-group Comparisons
386
+ Between groups comparison showed that there was a significant
387
+ difference in post scores of both the groups in the following
388
+ assessments: CRP (p<0.001), SCI-QoL Index (p<0.05), MEDS
389
+ (p<0.001). However, ASIA (p=0.241), SCIM (p=0.069), and BMI
390
+ (p=0.475) scores were not significantly different [Table/Fig-7]. The
391
+ male participants in IYP (n=54) and PT (n=53) showed that there was
392
+ no significant difference in BMI (p=0.729), SCI-QOL Index (p=0.12),
393
+ SCIM (p=0.109), but a significant difference in MEDS (p<0.001) in
394
+ post scores of both groups. Similarly, female participants in IYP (n=8)
395
+ and in PT (n=9) also demonstrated significant difference in SCI-QOL
396
+ Index (p=0.012), and MEDS (p=0.019), but no significant difference in
397
+ BMI (p=0.280) and SCIM (p=0.452) when post compared with post.

697
+ DISCUSSION
698
+ This is the first randomised control trial of yoga in SCI which was
699
+ done to compare the effect of IYP to PT in the management of
700
+ SCI patients on ASIA score, functional independence, distress, an
701
+ inflammatory marker, quality of life and BMI. The strength of the
702
+ study is its study design and the large sample size. The percentage
703
+ change in the post scores of ASIA, BMI, SCI-Qol, SCIM, MEDS
704
+ and CRP is higher in IYP than the PT group, when compared with
705
+ pre-scores. Similarly, between groups comparison showed IYP
706
+ group had significantly better improvement in SCI-QoL, MEDS and
707
+ CRP
708
+ , than PT group which suggest that yoga therapy could be a
709
+ feasible, cost-effective, easy-to-accomplish, non-pharmacological
710
+ intervention aiding rehabilitation of paraplegics.
711
+ The non-pharmacological approach of yoga therapy [28,29] which
712
+ encompass a combination of physical postures, voluntary breathing
713
+ practices, cleansing techniques, concentration and relaxation
714
+ techniques [30]. As observed in the outcomes, the positive changes
715
+ in the IYP group compared to PT group may be due to psychological
716
+ benefits; calming effect, increasing awareness, attention span,
717
+ acceptance, adaptability and a sense of security resulting from the
718
+ practice of yoga therapy [31]. The process adopted during the yoga
719
+ program included stimulation and successively followed by relaxation
720
+ might have helped in breaking the loop of the uncontrolled speed of
721
+ thoughts (stress) [32] and better psychological health resulting from
722
+ stress reduction [33] through slowly gaining mastery over the mind
723
+ [34]. Increase in thalamic GABA levels, improvement in mood and
724
+ anxiety levels, and a decrease in depressive symptoms has been
725
+ demonstrated by 12 weeks of yoga practice, in two recent studies
726
+ [35,36]. A possible mechanism is explored hereunder.
727
+ There is strong evidence showing an association of raised CRP
728
+ with chronic SCI which is mainly due to prevailing systemic
729
+ inflammation and not due to any infection condition [8,37,38].
730
+ As per the study protocol, authors wanted to observe whether
731
+ the add-on of yoga therapy does improve chronic systemic
732
+ inflammation in patients who have already undergone their primary
733
+ rehabilitation. The reduction in CRP scores indicates a significant
734
+ reduction in systemic inflammation in IYP group in comparison to
735
+ the PT group. Reduction in inflammation can be directly attributed
736
+ to a significant decrease in stress in the IYP group. Yoga has a
737
+ beneficial impact on reducing stress than simple exercises, as
738
+ shown in previous studies [39]. Relaxation and calming effect is
739
+ unique to yoga which in turn helps to modulates Hypothalamus-
740
+ Pituitary-Adrenal-Axis (HPA-axis) and resulted in reducing
741
+ inflammation [40]. It is likely that yoga practice improves immune
742
+ function [41] and this could add to bring a significant change in
743
+ the parameters measured.
744
+ The present study reported the functional improvement (in areas
745
+ such as self-care, respiration, sphincter management and mobility)
746
+ is better in IYP group (% change=17.35%) as indicated by SCIM
747
+ scores as compared to PT group (% change=5.64%), though no
748
+ significant differences were observed in between the two groups.
749
+ This finding aligns with the results of another clinical trial on
750
+ paraplegics where there was a highly significant improvement in
751
+ spasticity and gait after receiving yoga therapy [42].
752
+ Emotional distress is well managed by yoga which is reflected
753
+ in the reduction of symptoms score of MEDS. Improvement in
754
+ emotional distress results in decreased sympathetic activity and
755
+ may be attributed to better autonomic modulation. The function
756
+ of the Autonomic Nervous System (ANS) becomes more specific
757
+ resulting in a tilt in balance in favour of the Parasympathetic
758
+ Nervous System (PNS), in turn resulting in emotional stability and
759
+ distress reduction [11]. Previous studies have shown that yogic
760
+ practices handle anxiety and depression well, resulting in enhanced
761
+ self-esteem and betterment in performances of Activities of Daily
762
+ Living (ADL) [43]. A six-week specialised yoga program has shown
763
+ similar results where there have been significant improvements in
764
+ depressive symptoms, mindfulness and self-compassion in yoga
765
+ group compared to control [13]. Thus, improvement in SCI-QoL
766
+ Index can be attributed to improvement in psychological states
767
+ due to yogic practices.
768
+ Yoga postures (asanas) are targeted to extend the spine in controlled
769
+ measure and also to twist the spine gently. These asanas could
770
+ increase blood flow in the spinal arteries and thus bring improved
771
+ oxygen with increased healing possibilities, as demonstrated by a
772
+ previous study [15]. Neural tissue plasticity can be promoted by
773
+ several factors including neurotrophic factors, neurotransmitters,
774
+ endocrines, cytoskeleton proteins and neuronal electrical activity
775
+ to name a few [16]. The practice of yoga can enhance the above
776
+ mentioned factors and could have possibly increased the production
777
+ of neurotrophic factors (e.g., -BDNF, VEGF, IGF-1 etc.,) that would
778
+ have mediated neurogenesis and neuroplasticity [44,45]. This, in
779
+ turn, is likely to improve sensory, motor and autonomic function in
780
+ SCI patients. Hence, the current study clearly showed that because
781
+ of add-on of yoga therapy, improvements in IYP group was better
782
+ than the PT group [Table/Fig-8].
783
+ [Table/Fig-8]: Summarises possible mechanism for add-on yoga module in
784
+ improving patient outcomes in SCI.
785
+ Though both groups (IYP and PT) showed improvements in the
786
+ scores of BMI and ASIA, the magnitude of change was higher in
787
+ participants of IYP group compared to participants of the PT group.
788
+ This indicates that add-on of yoga therapy with physiotherapy,
789
+ increases basal metabolic rate, enhancing metabolism and more fat
790
+ oxidation [46]. Therefore, better metabolic regulation has resulted in
791
+ weight reduction and improvement in sensory and motor function
792
+ leading to better mobility.
793
+ LIMITATION
794
+ The main limitation of the study was that it was conducted on
795
+ paraplegia patients belonging to one rehabilitation centre and the
796
+ results were not able to rule out the effect of other rehabilitation
797
+ activities such as vocational training and occupational therapy.
798
+ Hence more studies are needed including more centres.
799
+ CONCLUSION
800
+ Authors conclude that improvements in stress resulted in a
801
+ decrease in inflammation and enhanced emotional stability resulting
802
+ from better autonomic modulation. Improvement in psychological
803
+ states resulted in better QoL, and reduction in BMI increased Basal
804
+ Metabolic Rate (BMR), leading to significant improvement in overall
805
+ functional independence. The study might be improvised in design
806
+ by further conducting a multi-centric trial and including radiological
807
+ investigations for a better understanding of the underlying processes
808
+ involved.

+ Abstract
67
+ Introduction: Yoga is the science of right living practice to promote health. Many studies have
68
+ documented the cardiovascular effects of various yogic breathing techniques (YBTs), comparing the
69
+ cardiovascular changes before and after the practice. However, there is a lack of study reporting
70
+ the cardiovascular changes during the practice of YBT. Materials and Methods: Twenty healthy
71
+ individuals performed four different YBTs  (Bhastrika, Bhramari, Kapalbhati, and Kumbhaka)
72
+ in four different orders. Cardiovascular variables such as systolic blood pressure  (SBP), diastolic
73
+ blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR), stroke volume (SV), cardiac
74
+ output (CO), pulse interval (PI), and total peripheral resistant (TPR) were assessed using a continuous
75
+ noninvasive blood pressure monitoring system, before, during, and immediately after each YBT.
76
+ Data were analyzed using repeated measures analysis of variance followed by post hoc analysis with
77
+ Bonferroni adjustment for multiple comparisons using Statistical Package for the Social Sciences,
78
+ Version  16.0. Results: Results of this study showed a significant increase in DBP, MAP, HR, and
79
+ CO along with a reduction in PI during Bhastrika; a significant increase in DBP, MAP, HR, and
80
+ TPR with a reduction in SV, CO, and PI during Bhramari pranayama; a significant increase in SBP,
81
+ DBP, MAP, HR, and CO with a reduction in PI during Kapalbhati; and a significant increase in SBP,
82
+ DBP, MAP, and TPR with a reduction in SV and CO during Kumbhaka practice. Conclusion: In
83
+ healthy individuals, cardiovascular changes during the practice of Bhastrika and Kapalbhati are more
84
+ or less similar to each other and are different from those of Bhramari and Kumbhaka in most of the
85
+ variables.

160
+ Participants
161
+ Twenty healthy individuals with the mean  (standard
162
+ deviation) age of 23.40 (3.05) years were recruited from a
163
+ residential university located in South India. Both male and
164
+ female participants aged 18 years and above and willing to
165
+ participate in the study were included, while participants
166
+ with a history of any illness (systemic or mental), chronic
167
+ smoking, or alcoholism and the participant who is not
168
+ able to perform the selected YBT were excluded. The
169
+ study protocol was approved by the Institutional Ethics
170
+ Committee,
171
+ S‑VYASA 
172
+ (Deemed

177
+ (RES/IEC‑SVYASA/76/2015),
178

181
+ The study design
182
+ A single‑group repeated measures design was adopted,
183
+ in which all participants performed four different types
184
+ of YBT in four different orders. The order was randomly
185
+ selected using a lottery method as follows: twenty
186
+ papers (five containing the word “Bhastrika” [i.e., 1st order],
187
+ five containing the word “Bhramari”  [i.e., 2nd order], five
188
+ containing the word “Kapalbhati” [i.e., 3rd order], and five
189
+ containing the word “Kumbhaka” [i.e., 4th order]) were put
190
+ in an envelope, and each participant was asked to draw
191
+ a paper from the envelope. The paper each participant
192
+ drew out determined the order in which the respective
193
+ YBTs were done.[2] In the first order  (n  =  5), participants
194
+ performed Bhastrika followed by Bhramari, Kapalbhati,
195
+ and Kumbhaka; in the second order  (n  =  5), participants
196
+ performed Bhramari followed by Kapalbhati, Kumbhaka,
197
+ and Bhastrika; in the third order  (n  =  5), participants
198
+ performed Kapalbhati followed by Kumbhaka, Bhastrika,
199
+ and Bhramari; and in the fourth order (n = 5), participants
200
+ performed Kumbhaka followed by Bhastrika, Bhramari,
201
+ and Kapalbhati with the interval of 5  min between each
202
+ YBT. Baseline assessment was taken at rest before starting
203
+ of the YBT, whereas during and post assessments were
204
+ taken during and immediately after each YBT.

+ mean arterial pressure  (MAP), heart rate  (HR), stroke
219
+ volume  (SV), cardiac output  (CO), pulse interval  (PI),
220
+ and total peripheral resistant  (TPR) were assessed in a
221
+ sitting position using a noninvasive blood pressure  (BP)
222
+ monitoring system  (Finapres Continuous Non‑Invasive
223
+ Blood Pressure Systems, Netherlands). A  finger cuff was
224
+ positioned in between the interphalangeal joints of the
225
+ left middle finger. A  noninvasive BP cuff was positioned
226
+ on the left upper arm at heart level and ensured that the
227
+ cuff marker was directly above the brachial artery. The
228
+ elbows were flexed and the hands were kept on the knees.
229
+ The brachial correction was made before assessment and
230
+ assessments were taken at rest  (during normal breathing)
231
+ before starting of the YBT  (baseline), during, and
232
+ immediately after each YBT.
233
+ Intervention
234
+ Bhastrika (5 min)
235
+ Participants were asked to perform forceful inhalation and
236
+ forceful exhalation through both nostrils for the duration
237
+ of 1  min. This is one round and it was repeated for three
238
+ rounds with a rest (normal breath) period of 1 min between
239
+ each round.[1]
240
+ Bhramari (5 min)
241
+ Participants were asked to perform inhalation through both
242
+ nostrils and then while exhaling should produce sound of a
243
+ humming bee for the duration of 5 min.[2]
244
+ Kapalbhati (5 min)
245
+ Participants were asked to perform forceful exhalation
246
+ followed by normal inhalation through both nostrils[1]
247
+ for the duration of 1  min. This is one round and it was
248
+ repeated for three rounds with a rest (normal breath) period
249
+ of 1 min between each round.
250
+ Kumbhaka (breath retention) (5 min)
251
+ Participants were asked to take a deep inhalation through both
252
+ nostrils, followed by a voluntary breath‑holding/retention[1]
253
+ by closing the right and left nostrils using participants’
254
+ thumb and ring finger of the right hand, respectively, for
255
+ the duration of 1 min. Then, the participants were asked to
256
+ slowly exhale through both nostrils and maintain the normal
257
+ breath for 1  min. The same procedure was repeated for
258
+ another two times  (total 3  times of breath‑holding  [1  min
259
+ each] with a rest  [normal breath] period of 1  min between
260
+ each breath‑holding). The time of breath‑holding and rest
261
+ period was maintained using a stopwatch. To ensure the
262
+ breath‑holding, respiration was monitored using a volumetric
263
+ pressure transducer fixed around the trunk about 8 cm below
264
+ the lower costal margin while the participants sat erect.
265
+ Data extraction
266
+ Brachial artery SBP and DBP were derived from finger
267
+ arterial pressure using a height correction unit and
268
+ waveform filtering and level correction methods supplied by
269
+ the BeatScope software package (Finapres Medical Systems
270
+ B.V., 184 Netherlands).[3, 12] SV, CO, and TPR were also
271
+ derived from the standard formula using BeatScope Easy

292
+ Results
293
+ Of 36 participants, 16 participants did not fulfill the
294

295
+ Recruited twenty participants’ data were collected and
296
+ performed the analysis. The details of the results are
297
+ provided in Table 1.
298
+ Bhastrika
299
+ During Bhastrika practice, a significant increase in DBP,
300
+ MAP, HR, and CO along with a significant reduction in PI
301
+ was observed. In the recovery period, the increase in DBP,
302
+ MAP, and HR along with a reduction in PI was sustained.
303
+ Bhramari
304
+ During Bhramari practice, a significant increase in DBP,
305
+ MAP, HR, and TPR with a significant reduction in SV, CO,
306
+ and PI was observed. In the recovery period, the reduction
307
+ in SV and CO was sustained, whereas the rest of the
308
+ variables revert back to normal.
309
+ Kapalbhati
310
+ During Kapalbhati practice, a significant increase in SBP,
311
+ DBP, MAP, HR, and CO with a significant reduction in PI
312
+ was observed. In the recovery period, the increase in DBP
313
+ and HR along with a reduction in PI was sustained.
314
+ Kumbhaka
315
+ During Kumbhaka practice, a significant increase in SBP,
316
+ DBP, MAP, and TPR with a significant reduction in SV and
317
+ CO was observed. In the recovery period, the increase in
318
+ MAP was sustained, whereas the rest of the variables revert
319
+ back to normal.
320
+ Discussion
321
+ Autonomic nervous system plays a vital role in regulating
322
+ and maintaining the cardiovascular functions, such as
323
+ SBP, DBP, and HR.[13] Literature suggests that SBP is the
324
+ byproduct of peripheral resistance (PR) and CO, in which CO
325
+ is the byproduct of SV and HR.[14] The results of this study
326
+ showed a significant increase in SBP during the practice of
327
+ Kapalbhati and Kumbhaka  (Kumbhaka  >  Kapalbhati). In
328
+ Kapalbhati, a significant increase in SBP might attribute to
329
+ the significant increase in CO due to a significant increase
330
+ in HR during the practice. However, in Kumbhaka, the
331
+ significant increase in SBP might attribute to the significant
332
+ increase in TPR during the practice. Hence, Kapalbhati
333
+ increases SBP by increasing CO through increased HR,
334
+ whereas Kumbhaka increases SBP by increasing TPR.

+ Although there was a significant increase in DBP during all

+ YBTs (Kumbhaka > Bhramari > Kapalbhati > Bhastrika),
440

443
+ during all YBTs, the contributing factors are different in

+ different YBTs. For example, the increased DBP during

+ Bhastrika and Kapalbhati might attribute to the significant
446
+ increase in HR and CO; during the Bhramari, it might
447
+ attribute to the significant increase in HR and TPR; and
448
+ during the Kumbhaka, it might attribute to the significant
449
+ increase in TPR. The sustained increase in DBP even after
450
+ the practice of Kapalbhati and Bhastrika could be due to
451
+ the sustained increased level of HR after these practices.

456
+ MAP
457
+ during
458
+ all
459
+ YBTs  (Kumbhaka  >  Kapalbhati  >  Bhramari  >  Bhastrika)
460
+ might attribute to the significant increase in DBP during
461
+ all the practices because MAP is the byproduct of DBP
462
+ and pulse pressure. MAP reverts back to normal only after
463
+ Bhramari and Kapalbhati, and this could possibly be due
464
+ to the reduction in the TPR after Bhramari and CO after
465
+ Kapalbhati.
466
+ A significant increase in HR and reduction in PI were
467
+ observed in Bhastrika  >  Kapalbhati  >  Bhramari, no such
468
+ significant change was observed during Kumbhaka, and
469
+ it was sustained after Bhastrika  >  Kapalbhati and revert
470
+ back to normal after Bhramari. It might have attributed to
471
+ the increased breath rate during the practice of Bhastrika
472
+ and Kapalbhati, whereas the significant increase in HR
473
+ and reduction in PI during Bhramari might attribute to
474
+ parasympathetic withdrawal.[15]
475
+ During
476
+ Bhramari
477
+ and
478
+ Kumbhaka,
479
+ a
480
+ significant
481
+ reduction
482
+ in
483
+ SV 
484
+ (Bhramari 
485
+
486
+ Kumbhaka)
487
+ and
488
+ CO  (Kumbhaka  >  Bhramari) was observed but the
489
+ reduction was sustained only after Bhramari and revert
490
+ back to normal after Kumbhaka. The reduction in the CO
491
+ might be due to the significant reduction in the SV. In
492
+ contrast to Bhramari and Kumbhaka, there was a significant
493
+ increase in CO during Kapalbhati and Bhastrika. This
494
+ effect could be due to the significant increase in HR during
495
+ these practices.
496
+ During Bhramari and Kumbhaka, a significant increase
497
+ in TPR  (Kumbhaka  >  Bhramari) was observed and revert
498
+ back to normal after the practice. The reason for this
499
+ change is not clear, and thus, it needs to be explored in the
500
+ future studies.
501
+ The exact mechanism of the YBT on cardiovascular
502
+ functions is not well defined. However, the possible
503
+ mechanisms
504
+ for
505
+ the
506
+ effect
507
+ of
508
+ various YBTs
509
+ are
510
+ as
511
+ follows:
512
+ Literature
513
+ suggests
514
+ that
515
+ slow‑pace
516
+ Bhastrika  (6 breaths/minute) produces a reduction in
517
+ BP and HR  (indicative of parasympathetic activation),
518
+ while fast‑pace Bhastrika  (>60 breaths/minute) produces
519
+ an increase in HR, rate pressure product, and double
520
+ product[13] (indicative of an increase in load on the heart and
521
+ subsequent reduction in HR variability  [HRV]).[14] Thus,
522
+ the cardiovascular effect of fast‑pace Bhastrika provided
523
+ in our study might be attributed to increased workload on
524
+ the heart and reduced HRV due to increased sympathetic
525
+ activation or reduced parasympathetic activity.
526
+ Evidence suggests that Kapalbhati increases low‑frequency
527
+ (LF) spectrum of HRV, and LF: HF ratio and reduces
528
+ high‑frequency (HF) spectrum of HRV, indicating increase
529
+ in sympathetic activity[4] or reduction in parasympathetic
530
+ activity and arterial baroreflex sensitivity.[4,13,16] The
531
+ cardiovascular findings of the study during Kapalbhati are
532
+ consistent with the previous study findings (i.e., increase in
533
+ SBP, DBP, and HR).[16] Thus, the cardiovascular changes
534
+ during the Kapalbhati practice might be attributed to
535
+ sympathetic arousal or reduced vagal tone and/or reduced
536
+ baroreflex sensitivity.
537
+ A previous study showed an increase in the LF spectrum
538
+ of HRV and a reduction in the HF spectrum of HRV and
539
+ time‑domain variables  (indicative of parasympathetic
540
+ withdrawal)
541
+ during
542
+ Bhramari
543
+ practice.[15]
544
+ Likewise,
545
+ literature suggests that breath retention leads to increased
546
+ sympathetic tone in response to hypoxia and hypercapnia.[3]
547
+ Results of the present study showed a significant increase
548
+ in TPR  (indicative of a possible sympathetic shift in the
549
+ autonomic activity)[4] during Bhramari and Kumbhaka
550
+ practice. Breathing at the resonant frequency and breath
551
+ retention has been shown to reduce the circulatory load
552
+ by improving oxygen saturation and gaseous exchange.
553
+ Thus, the reduction in SV and CO during Bhramari and
554
+ Kumbhaka might be a result of the body’s compensatory
555
+ mechanism to either increased TPR or low circulatory
556
+ load.[4] Hence, cardiovascular changes during Bhramari
557
+ and Kumbhaka might be due to either parasympathetic
558
+ withdrawal or sympathetic activity.
559
+ In summary, cardiovascular changes during Bhastrika,
560
+ Kapalbhati, Bhramari, and Kapalbhati might be due
561
+ to either parasympathetic withdrawal or sympathetic
562
+ activity. It might be due to the nature of intervention that
563
+ needed constant attention during the practice. However,
564
+ the results of the study suggest that during the fast YBT,
565
+ parasympathetic withdrawal or sympathetic activity might
566
+ have influenced the cardiovascular functions by directly
567
+ acting on the central, i.e., the heart (i.e., by increasing the
568
+ workload of the heart as indicated by increased HR and
569
+ CO), while during Bhramari and Kumbhaka, it might have
570
+ influenced the cardiovascular functions by acting on the
571
+ peripheral  (i.e., by increasing peripheral vasoconstriction
572
+ as indicated by increased TPR). Moreover, the results of
573
+ the study also suggest that the parasympathetic withdrawal
574
+ or sympathetic activity was sustained even after fast
575
+ YBT  (i.e., Bhastrika and Kapalbhati), while it was
576
+ reverted back to normal immediately after Bhramari and

584
+ Strengths of the study are  (i) this is the first study
585
+ evaluating the cardiovascular effect of selected YBT during
586
+ the practice itself, and  (ii) beat‑to‑beat changes in the BP
587
+ were measured using a standard, advanced, noninvasive BP
588
+ monitoring system.  Limitations of the study are  (i) small
589

+ based on any previous study, and  (iii) assessments such
591

593

595

26
+ 1. Background
27
+ Developing countries such as India, China, and Indonesia are
28
+ projected to have the largest number of elderly by 2025 (Hariprasad
29
+ et al., 2013a,b,c,d). The elderly population in India is estimated to
30
+ increase from 71 million in 2001 to 179 million in 2031 (Hariprasad
31
+ et al., 2013a,b,c,d). Similarly, in developed countries like United
32
+ States of America, between 1980 and 2010, the proportion of over-
33
+ 65 years rose from 11% to 13% (varies from 8% in Alaska to 17% in
34
+ Florida) and by 2030, and 2050, the proportions would be expected
35
+ to rise up to 19%, and 20% respectively (Barbieri and Ouellette,
36
+ 2012). More than 50% of the elderly above 60 years of age, suffer
37
+ from chronic medical conditions and its prevalence and severity
38
+ increases with age (Hariprasad et al., 2013a,b,c,d). The aging pro-
39
+ cess always involves functional, physiological and biochemical
40
+ changes that reduce one's ability to perform daily activities
41
+ (Ramos-Jim
42
+ enez et al., 2009). Aging is also associated with multiple
43
+ medical conditions (both physical and psychological) mainly due to
44
+ deteriorating
45
+ physiological
46
+ reserves
47
+ and
48
+ impaired
49
+ immune
50
+ mechanisms which lead to poor quality of sleep and quality of life
51
+ (Hariprasad et al., 2013a,b,c,d).
52
+ Yoga is an ancient Vedic science and a way of life, believed to
53
+ have originated in India around 5000 BC which is being increas-
54
+ ingly applied in the field of therapeutics (Singh et al., 2008). It in-
55
+ cludes the practice of moral observances (Yama), self-disciplines
56
+ (Niyamas), specific posture (asana), regulated breathing (Pra-
57
+ nayama), Sensory withdrawal (Pratyahara), Concentration (Dhar-
58
+ ana), Meditation (Dhyana), and self-realization (Samadhi) (Gard
59
+ et al., 2014). Increasing number of elderly adults are practising
60
+ yoga in recent years (Wang et al., 2013) and these yogic practices
61
+ are also reported to promote healthy aging (Hariprasad et al.,
62
+ 2013a,b,c,d). Though Yoga has been reported as an effective mo-
63
+ dality in improving various physical and psychological aspects of
64
+ elderly populations, a comprehensive review on the effects of yoga
65
+ on the health problems faced by elderly population is not available.
66
+ Hence, this current review aims to provide a comprehensive review
67
+ using the current available scientific literature on the effect of yoga
68
+ in elderly.

77
+ 2. Methods
78
+ We performed a comprehensive search in the PubMed/Medline
79
+ electronic database to review relevant articles, using keywords
80
+ “yoga and elderly”. A total of 1044 articles published from 1965 to
81
+ 06th October 2016 were available. All the relevant articles that fit
82
+ into the following inclusion and exclusion criteria were reported in
83
+ this review. Inclusion criteria: Clinical trials, controlled trials, ran-
84
+ domized controlled trials, systematic reviews and meta-analysis
85
+ that are dealing with Yoga alone or in combination with conven-
86
+ tional medicines in elderly. Exclusion criteria: Research protocols,
87
+ comments, articles that do not have either abstract or full text,
88
+ articles that are dealing with Yoga in combination with other
89
+ complementary and alternative therapies, articles with lack/repe-
90
+ tition of the same kind of information. Of 1044 articles, 47 articles
91
+ published from 1997 to 6th October 2016 were included in this
92
+ review.
93
+ 3. Practice of yoga and its effects in elderly peoples
94
+ In general, Yoga was reported to have beneficial effect on
95
+ physical function, mental/emotional state (Alexander et al., 2013),
96
+ social, vitality (Halpern et al., 2014), and lifestyle choices. And thus,
97
+ it might be useful as a health promotion strategy in the prevention
98
+ and management of chronic disease in older adults (Alexander
99
+ et al., 2013). According to a systematic review and meta-analysis
100
+ Yoga is superior to conventional physical activity interventions in
101
+ elderly people especially in improving for self-rated health status,
102
+ aerobic fitness, and strength (Patel et al., 2012). The effect of Yoga
103
+ on various systems and its related problems were discussed below.
104
+ 3.1. Cardiovascular system and its related problems
105
+ Ageing is associated with a decline in heart rate variability and
106
+ spontaneous decline in baroreceptor sensitivity whereas 4-month
107
+ (2 classes/week plus home exercises) of yogic respiratory training
108
+ was reported to produce beneficial effects by reducing cardiac
109
+ sympathetic activity and improved sympathovagal balance in
110
+ elderly individuals (Santaella et al., 2011). Oxidative stress has been
111
+ implicated as one of the underlying cause of hypertension. Hy-
112
+ pertension, especially in the elderly is a strong risk factor for car-
113
+ diovascular mortality and morbidity. A 3-month Yoga (1-h in the
114
+ morning for 6-days per week) intervention has shown to reduce
115
+ oxidative stress by showing a significant reduction in serum
116
+ malondialdehyde levels and an increase in antioxidant levels
117
+ (serum superoxide dismutase activity, serum glutathione, and
118
+ vitamin C). Thus, Yoga was reported to be effective in reducing
119
+ oxidative stress and to improve antioxidant defense in elderly hy-
120
+ pertensive individuals (Patil et al., 2014).
121
+ Twelve week of Yoga has shown to produce significant reduc-
122
+ tion in heart rate (Bezerra et al., 2014) and 11 week of Hatha-Yoga (5
123
+ sessions/week for 90 min) was shown to produce significant in-
124
+ crease in maximal oxygen consumption and maximal expired air
125
+ volume and high-density lipoprotein cholesterol in elderly women
126
+ (Ramos-Jim
127
+ enez et al., 2009). In a study involving 12 weeks (1-h in
128
+ the morning for 6 days in a week) of Yoga a significant reduction in
129
+ arterial stiffness, blood pressure, sympathetic activity and an
130
+ improvement in endothelial function and enhanced bioavailability
131
+ of nitric oxide was observed in elderly individuals, along with an
132
+ increase in pulse pressure (Patil et al., 2015). In another study 8-
133
+ weeks of Bikram yoga (90 min per session, three times per week),
134
+ an improvement in arterial stiffness was reported only in young,
135
+ but not in older adults (Hunter et al., 2013a,b).
136
+ Baroreflex sensitivity is quantified by the alpha-index, at high
137
+ frequency (0.15e0.35 Hz, reflecting parasympathetic activity) and
138
+ mid-frequency (MF; 0.05e0.15 Hz, reflecting sympathetic activity)
139
+ derived from spectral and cross-spectral analysis of spontaneous
140
+ fluctuations in heart rate and blood pressure. Six weeks of Yoga
141
+ practice was shown to reduce heart rate and increase alpha high
142
+ frequency, suggestive of parasympathetic activity in healthy elderly
143
+ persons (Bowman et al., 1997).
144
+ 3.2. Respiratory system and its related problems
145
+ Ageing is associated with a decline in pulmonary function but 4-
146
+ months of (2 classes/week plus home exercises) Yogic breathing
147
+ practices have shown to be beneficial in improving respiratory
148
+ functions in elderly (Santaella et al., 2011) by reducing respiratory
149
+ rate and improving tidal volume, vital capacity, minute ventilation,
150
+ maximal inspiratory and expiratory pressure (Bezerra et al., 2014).
151
+ In elderly individuals, respiratory function may be seriously
152
+ compromised when a marked decrease in respiratory muscle
153
+ strength coexists with co-morbidity and activity limitation. But, 6
154
+ weeks (5 days per week) of Yogic breathing practice was reported
155
+ to be an effective and well-tolerated exercise regimen in elderly
156
+ individuals. Hence, yoga can be considered as a useful alternative to
157
+ inspiratory threshold training, or no training, to improve respira-
158
+ tory muscle function in elderly individuals, when whole-body ex-
159
+ ercise training is not possible (Cebri
160
+ a i Iranzo et al., 2014).
161
+ 3.3. Nervous system and its related problems
162
+ 3.3.1. Physical performance in parkinson disease
163
+ A 12 week Yoga study showed a significant improvement in
164
+ physical performance in elderly individuals with Parkinson disease
165
+ measured using the Unified Parkinson Disease Rating Scale motor
166
+ score, Berg Balance Scale, Mini-Balance Evaluation Systems Test,
167
+ Timed Up and Go, single leg stance, postural sway test, 10-m usual
168
+ and maximal walking speed tests, 1 repetition maximum and peak
169
+ power for leg press (Ni et al., 2016).
170
+ 3.3.2. Cognitive impairment and dementia
171
+ The elderly have an increased risk of cognitive impairment and
172
+ dementia (Hariprasad et al., 2013a,b,c,d). Yoga-based intervention
173
+ was reported to be a feasible intervention in the elderly with
174
+ cognitive impairments (Hariprasad et al., 2013a,b,c,d). The practice
175
+ of Yoga for 6 months was shown to be effective in increasing hip-
176
+ pocampal grey matter (Hariprasad et al., 2013a,b,c,d); in improving
177
+ immediate and delayed recall of verbal (Rey's Auditory Verbal
178
+ Learning Test) and visual memory (Rey's complex figure test),
179
+ attention and working memory (Wechsler's Memory Scale-spatial
180
+ span), verbal fluency (Controlled Oral Word Association), execu-
181
+ tive function (Stroop interference) and processing speed (Trail
182
+ Making Test-A) (Hariprasad et al., 2013a,b,c,d). One month practice
183
+ of Trataka (a Yogic visual cleansing technique), was shown to pro-
184
+ duce significant improvement in various cognitive tasks such as
185
+ Digit Span Scores, Six Letter Cancellation Test Scores and Trail
186
+ Making Test-B scores in elderly. Yoga could thus prove to be a
187
+ valuable tool to enhance cognition in the elderly (Talwadkar et al.,
188
+ 2014). Whereas, another study on 6 months of Hatha-Yoga, re-
189
+ ported no such significant improvement in cognitive functions
190
+ (Oken et al., 2006).
191
+ A study of 12-week (three 55-min sessions per week) Yoga
192
+ practice showed beneficial effects in individuals with dementia,
193
+ living in long-term care facilities in improving both physical (low-
194
+ ered blood pressure, reduced respiration rate, strengthened car-
195
+ diopulmonary fitness, enhanced body flexibility, improved muscle
196
+ strength and endurance, improved balance, and increased joints
197
+ motion) and mental health (reduction in depression state and
198
+ problem behaviours). Hence, yoga could usefully be recommended
199
+ A. Mooventhan, L. Nivethitha / Journal of Bodywork & Movement Therapies 21 (2017) 1028e1032
200
+ 1029
201
+ as one of the routine activities in the long-term care facilities (Fan
202
+ and Chen, 2011).
203
+ 3.4. Mental health and its related problems
204
+ Yoga influences both the physiological and psychological as-
205
+ pects of aging (Wang et al., 2014). In a study, 6-week of yoga was
206
+ demonstrated to be effective in improving psychological wellbeing
207
+ by reducing anger, anxiety, depression and self-efficacy for daily
208
+ living of elderly individuals (Bonura and Tenenbaum, 2014). In
209
+ other studies, 7-week of Yoga was demonstrated to be effective in
210
+ improving mental/emotional wellness, exhaustion levels, and
211
+ stress levels (Lindahl et al., 2016); and 8-week of yoga effectively
212
+ improved the performance of executive function measures such as
213
+ working memory capacity and efficiency in mental set shifting in
214
+ elderly individuals (Gothe et al., 2014).
215
+ A 24 weeks (7 h 30 min per week) study of an integrated
216
+ approach of yoga including the mental and philosophical aspects, in
217
+ addition to the physical practices, was shown to help in reducing
218
+ depression in institutionalized older individuals (Krishnamurthy
219
+ and Telles, 2007). In another study, laughter Yoga reduced
220
+ depression and improved life satisfaction of elderly depressed
221
+ women and was found to be as effective as group exercise pro-
222
+ grams. (Shahidi et al., 2011). A systematic review also reported Yoga
223
+ to be effective in reducing depressive symptoms of elderly people
224
+ living in institutions and in the community (Wang et al., 2014).
225
+ 3.5. Musculoskeletal system and its related problems
226
+ Falls are amongst the most common problems affecting elderly
227
+ individuals. At least 50% of those over the age of 80 fall annually
228
+ (Galantino et al., 2012). Twelve weeks of Yoga practice was shown
229
+ to be as effective as Tai-Chi and standard balance training in
230
+ improving postural stability in the elderly (Ni et al., 2014). In a
231
+ systematic review and Meta-analysis, yoga was reported to result in
232
+ small improvements in balance and medium improvements in
233
+ physical mobility in elderly people (Youkhana et al., 2016). An 8-
234
+ week (two 90-min sessions per week, and at least 20 min of on
235
+ alternate days) Iyengar Hatha yoga program specifically tailored to
236
+ the elderly was reported to be safe, feasible and to provide a
237
+ beneficial effect in preventing or reducing age-related changes of
238
+ gait function (Di Benedetto et al., 2005), while a chair based yoga
239
+ program was reported to be effective in improving mobility and
240
+ reducing the fear of falling. Moreover, there were no adverse events
241
+ during the Yoga sessions (Galantino et al., 2012).
242
+ Yoga was reported to have ancillary benefits in terms of
243
+ improved physical function (Alexander et al., 2013), and reduced
244
+ fatigue (Halpern et al., 2014). A previous study on 32 weeks (two
245
+ 60-min sessions per week) of Hatha yoga for elderly people
246
+ demonstrated the demand of various individual standing yoga
247
+ poses at the ankle, knee and hip, in the frontal and sagittal planes.
248
+ In these, the Crescent, Chair, Warrior II, and One-legged Balance
249
+ poses were shown to generate the greatest average support mo-
250
+ ments; Side Stretch was shown to generate the greatest average hip
251
+ extensor and knee flexor joint moments of force (JMOFs); Crescent
252
+ pose was shown to have the highest demands on the hip flexors and
253
+ knee extensors; and all the poses were shown to produce ankle
254
+ plantar-flexor JMOFs. In the frontal plane, the Tree pose was shown
255
+ to generate the greatest average hip and knee abductor JMOFs;
256
+ whereas Warrior II pose was shown to generate the greatest
257
+ average hip and knee adductor JMOFs. The Warrior II and One-
258
+ legged Balance induced the largest average ankle evertor and
259
+ invertor JMOFs, respectively. The electromyographic findings were
260
+ also shown to be consistent with the JMOF results (Wang et al.,
261
+ 2013).
262
+ In various previous studies, practice of Yoga improved flexibility
263
+ (Oken et al., 2006; Farinatti et al., 2014), hip extension, stride length
264
+ (Di Benedetto et al., 2005), range of motion (Gonçalves et al., 2011),
265
+ standing balance, sit-to-stand test (Tiedemann et al., 2013), one-
266
+ legged stand with eyes closed test score (Oken et al., 2006;
267
+ Tiedemann et al., 2013), Four Minute Walk Test score (Tiedemann
268
+ et al., 2013), Six-Minute Walk Test score (McCaffrey et al., 2014),
269
+ mobility (Kelley et al., 2014), postural control and gait (McCaffrey
270
+ et al., 2014; Kelley et al., 2014; Zettergren et al., 2011) and
271
+ decreased anterior pelvic tilt (Di Benedetto et al., 2005).
272
+ A cross-sectional survey of a nationally-representative sample
273
+ of women aged 60e65 years from the Australian Longitudinal
274
+ Study on Women's Health (ALSWH) showed the use of yoga/
275
+ meditation to be useful for management of back pain (Murthy et al.,
276
+ 2014). In a study on older women with knee osteoarthritis, 8-week
277
+ Yoga program was shown to be safe, feasible, acceptable and
278
+ effective in providing therapeutic benefits such as a significant
279
+ improvement in The Western Ontario and McMaster Universities
280
+ Arthritis Index (WOMAC) pain, stiffness and short physical perfor-
281
+ mance battery with no yoga related adverse events (Cheung et al.,
282
+ 2014). Similarly, a review was also reported as demonstratingYoga
283
+ to be useful in reducing pain in knee osteoarthritis without side
284
+ effects (Field, 2016).
285
+ 3.6. Metabolic disorders and its related problems
286
+ In a study of older adults with metabolic syndrome, 1-year of
287
+ Yoga practice was shown to improve the cardiovascular risk factors
288
+ including central obesity and blood pressure (Siu et al., 2015).
289
+ Bikram Yoga is an exotic form of physical activity combining hatha
290
+ yoga and thermal therapy that could positively impact metabolic
291
+ health. 8-week studies of Bikram Yoga were reported to produce a
292
+ significant improvement in glucose tolerance in elderly individuals
293
+ (Hunter et al., 2013a,b) and a significant reduction in insulin
294
+ resistance index in elderly individuals with obesity (Hunter et al.,
295
+ 2013a,b).
296
+ 3.7. Uro-genital system and its related problems
297
+ In a case study, a 63-year-old overweight female previously
298
+ diagnosed with stress urinary incontinence presented with exac-
299
+ erbated events of urine leakage. She was advised a residential
300
+ lifestyle and behavioural program, primarily consisting of a moni-
301
+ tored yoga therapy, apart from her ongoing anti-cholinergic med-
302
+ icine, for 21 days. Improvements were reported as “a total of 1.9 kg
303
+ of weight lossduring her stay. Usage of pad, as reported in her diary,
304
+ reduced from 3 to 1 per day. Her International Consultation on
305
+ Incontinence Modular Questionnaire-Urinary Incontinence Short
306
+ Form score reduced from 16 to 9, indicating better continence and
307
+ she expressed subjective well-being and confidence in her social
308
+ interactions” (Vinchurkar and Arankalle, 2015), suggesting that
309
+ yoga could be a possible complementary practise in the manage-
310
+ ment of incontinence and other uro-genital problems often asso-
311
+ ciated with age.
312
+ 3.8. Cancer and its related problems
313
+ Cancer and its treatments lead to cancer-related fatigue and
314
+ many other side effects, in turn, creating a substantial global side-
315
+ effect burden (total burden from all side effects) which, ulti-
316
+ mately, compromises functional independence and quality of life.
317
+ In a study, 4-week Yoga intervention was reported to be effective in
318
+ reducing cancer-related fatigue, physical fatigue, mental fatigue,
319
+ and global side-effect burden among older cancer survivors,
320
+ compared with standard care (Sprod et al., 2015). A study of a
321
+ A. Mooventhan, L. Nivethitha / Journal of Bodywork & Movement Therapies 21 (2017) 1028e1032
322
+ 1030
323
+ classical
324
+ Yoga
325
+ program (8-sessions), showed
326
+ a
327
+ reduction
328
+ in
329
+ depression, pain, fatigue amongst cancer patients with enhanced
330
+ performance of daily and routine activities, and increases in the
331
+ quality of life in elderly patients with breast cancer (Yagli and Ulger,
332
+ 2015).
333
+ 3.9. Quality of sleep and quality of life
334
+ The aging process is associated with physiological changes that
335
+ affect sleep. Sleep disturbances and decline in physical function-
336
+ ality are common conditions associated with aging (Bankar et al.,
337
+ 2013). Sleep in older persons is characterized by decreased ability
338
+ to stay asleep, resulting in fragmented sleep and reduced daytime
339
+ alertness (Manjunath and Telles, 2005). In older adults, undiag-
340
+ nosed and untreated insomnia may cause impaired daily function
341
+ and reduced quality of life. Insomnia is also a risk factor for acci-
342
+ dents and falls that are the main cause of accidental death in older
343
+ adults and, therefore associated with higher morbidity and mor-
344
+ tality rates in older populations (Halpern et al., 2014).
345
+ The pharmacological treatment of sleep disturbances (Bankar
346
+ et al., 2013) and insomnia in older persons (Manjunath and
347
+ Telles, 2005) is associated with various adverse effects (Bankar
348
+ et al., 2013; Manjunath and Telles, 2005). Whereas, practice of
349
+ Yoga has been shown to be effective in reducing the time taken to
350
+ fall asleep; in increasing the total number of hours slept (Halpern
351
+ et al., 2014; Manjunath and Telles, 2005) and in the feeling of be-
352
+ ing rested in the morning (Manjunath and Telles, 2005); in
353
+ improving overall sleep quality, sleep efficiency, and self-assessed
354
+ sleep quality (Halpern et al., 2014). Hence, regular practice of
355
+ Yoga was reported to be a safe intervention (Halpern et al., 2014;
356
+ Bankar et al., 2013) in improving different aspects of sleep
357
+ (Halpern et al., 2014; Manjunath and Telles, 2005), quality of sleep
358
+ (Hariprasad et al., 2013a,b,c,d; Bankar et al., 2013) and quality of life
359
+ (Hariprasad et al., 2013a,b,c,d; Halpern et al., 2014; Oken et al.,
360
+ 2006)
361
+ in
362
+ elderly
363
+ individuals
364
+ (Hariprasad
365
+ et
366
+ al.,
367
+ 2013a,b,c,d;
368
+ Halpern et al., 2014; Oken et al., 2006; Bankar et al., 2013). The
369
+ systematic reviews on Meditative Movement Intervention (a new
370
+ category of exercise integrating physical activity and meditation)
371
+ (Wu et al., 2015) and on Yoga (Wang et al., 2014) were also reported
372
+ to result in beneficial effects in improving the quality of sleep in
373
+ elder people (Wang et al., 2014; Wu et al., 2015).
374
+ 4. Conclusion
375
+ Based on the available scientific literature, this review suggests
376
+ that the regular practice of Yoga can be considered as an effective
377
+ intervention in improving various health related problems of
378
+ elderly people.

+ Introduction
3
+ Obesity  is a  metabolic disorder with excessive accumulation
4
+ of fat cells which leads to adverse impacts on physical as well as
5
+ psychological functions of theperson.1 Energy-dense overeating,
6
+ nutrient-poor foods and a sedentary lifestyle have led to an epidemic
7
+ of obesity all over the world.2 Apart from physical problems there
8
+ are issues which affect psychological well-being of an individual.
9
+ Depression is the commonest psychological co-morbidity of obesity.
10
+ A wide range of treatment options are available for obesity but,
11
+ balanced nutritional food intake and regular exercise are considered
12
+ to be the safest and the easiest option.3 The most common reason of
13
+ obesity is increased high calorie & irregular food intake, insufficient
14
+ exercise, and hereditary body pattern. 4 As per the leading scientist, if
15
+ not controlled vigorously it may end up in a serious health challenge
16
+ to the society.5 According to WHO, UNICEF & CARE it is one of the
17
+ most neglected public health problem in recent years.6
18
+ Adolescence is a transitional stage of physical and psychological
19
+ human development that occurs between the age of 13 and 19years.7
20
+ Overweight or obese children may continue this body pattern in
21
+ adulthood with same or increased levels which may lead to high risk
22
+ of developing disorders like diabetes, hypertension, cardiovascular
23
+ diseases and cancers.8 It has been observed that obesity in children has
24
+ dramatically increased over the past two decades.9 In the last decade,
25
+ 43million children were found overweight or obese. 35million of
26
+ this data were living in developing countries. This data may cross 60
27
+ million in coming dead if not managed with systematic & scientific
28
+ channels. Two systematic reviewpapers10,11 and one clinical review
29
+ paper12 suggest that yoga has beneficial effects on mental and
30
+ physical health in children and adolescents.
31
+ Yoga has been proved its efficacy in psychosomatic disorders
32
+ along with scientific evidence in past decade. Few national surveys
33
+ has reported that more than 10 million Americans are practicing yoga
34
+ for different health challenges since last 15yearss.13,14 Diseases due
35
+ to stress are found to be well managed with Yoga therapy according
36
+ to many scientific research article.15 Different schools of yoga have
37
+ varying proportions of physical, breathing, and mind activities
38
+ executed through varied practices. Most of these studies found a
39
+ varied range of positive benefits on obesity. They have a common
40
+ objective of voluntary mastery over the modifications of the mind.15
41
+ In order to provide yoga for adolescent obesity, we have designed
42
+ & developed an integrated yoga module for Obesity in adolescents
43
+ from authentic Yoga texts which were result of group discussion of
44
+ 16 subject matter experts. The module has been checked for content
45
+ validity by using Lawshe’s content validity ratio. This study is
46
+ accepted for publication in another publication. Now before going
47
+ for a proper randomised trial control in larger population, it needs
48
+ to be checked for feasibility on pilot basis. This study is designed to
49
+ provide feasibility of Integrated Yoga Module in overweight & obese
50
+ Adolescents. It also aims to objectively and rationally uncover the
51
+ strengths and weaknesses of the module. 17 It evaluates the project’s
52
+ potential for success.

+ Background
74
+ Yoga has been known to have stimulatory or inhibitory effects on the metabolic
75
+ parameters and to be uncomplicated therapy for obesity. Adolescence is more prone to
76
+ get obese due to lack of physical activity making them more sedentary.
77
+ Aim: To identify feasibility of validated Integrated Approach of yoga Therapy module
78
+ (IAYTM) for Obesity in adolescents.
79
+ Method: RCT (Randomized Controlled Trial) was conducted on overweight & obese
80
+ adolescents. Special yoga training was conducted for yoga group parameters like
81
+ weight, Body Mass Index (BMI), pulse rate , blood pressure, MAC (Mid Upper Arm
82
+ Circumferences), Waist Circumference (WC), HC (Hip Circumference), Fasting blood
83
+ sugar, total cholesterol, High-density lipoproteins, low-density lipoproteins, very low-
84
+ density lipoprotein & Sr. triglycerides were assessed before and after intervention for
85
+ both yoga and control groups. Within and between group analyses of the variables
86
+ were carried out.
87
+ Result: The study showed significant reduction in weight, body mass index, very low-
88
+ density lipoprotein & Sr. triglycerides, circumference & Serum cholesterol in yoga
89
+ group &percentage of improvement is more in yoga group than that of control group.
90
+ Conclusion: Integrated Approach of yoga Therapy module (IAYTM) is effective
91
+ in management of weight, serum triglyceride & very low - density lipoprotein in
92
+ adolescent obesity.

+ or guardians in the prior stage of intervention.
114
+ During intervention, Yoga group followed the Integrative Yoga
115
+ Therapy module for obesity in adolescents which contains body
116
+ posture, breathing tools, Relaxation and Meditation techniques. All
117
+ the techniques were conducted under guidance & expert’s observation.
118
+ Duration of each session of the intervention was 60minutes & sessions
119
+ were conducted for five days in a week for 1month. The control group
120
+ were doing regular physical activities. All participants received same
121
+ type of meal throughout the month. All the participants were assessed
122
+ for weight, BMI, pulse, blood pressure, mid-arm circumference
123
+ waist circumference, hip circumference, fasting blood sugar, serum
124
+ total cholesterol, high-density lipoprotein, low- density lipoprotein,
125
+ very low- density lipoprotein, serum triglycerides respectively at
126
+ baseline and after 1-month of the intervention. All the 23 adolescents
127
+ completed the intervention. There were no adverse effects observed
128
+ during the study period.
129
+ Data analysis
130
+ The data analysis was performed with SPSS software 20 th version.
131
+ In very beginning, the data was analysed for normal distribution.
132
+ Within groups analysis was analysed with all the variables. Between
133
+ groups analysis was conducted for the post variables of both the
134
+ groups.
135
+ Results
136
+ The basic demographic data of age and height of the yoga and
137
+ control group are given in Table 1. The average age of Yoga group was
138
+ 14.21±1.84 and that of control group was 15.22±1.09. The average
139
+ height of Yoga group was 1.64±0.09and that of control group was
140
+ 1.66±0.09. The minimum age in yoga group was 11 years whereas that
141
+ in control group was 14years and the maximum age in both groups
142
+ was 17years. The minimum height in yoga group was 1.51 meter and
143
+ that of control group was 1.54meter. The maximum height in yoga
144
+ group was 1.85 meter and that of control group was 1.75 meter.

525
+ Discussion
526
+ 23 adolescents were intervened by validated IYTM (36practices),
527
+ and they were assessed pre- and post-intervention for variables
528
+ out of which weight (P<0.001), Serum triglyceride & triglycerides
529
+ (P<0.001) & very low- density lipoprotein (P<0.001) showed
530
+ statistically significant reduction whereas waist circumference (P<
531
+ 0.45) & high - density lipoprotein (P<0.75) showed statistically non-
532
+ significant reduction by validated IYTM on obesity in yoga group.
533
+ This could be due to short duration of study. There was significant
534
+ reduction in BMI (p=0.001), pulse rate (p=0.038), hip circumference
535
+ (p=0.011), serum total cholesterol (p=0.035) in non –parametric test.
536
+ So this result cannot be implicated for the universe.
537
+ There is significant increase in mid-arm circumference (p=0.01)
538
+ with yoga group & (p=0.015) in control group. This could be
539
+ because that integrated approach of yoga therapy module for obesity
540
+ practises are having more emphasis on below naval part of body
541
+ especially focused on hips & thighs. Few practises were there like
542
+ suryanamaskara, chakarsana & Bhujangasana which was having
543
+ effect on arm muscles but they were not significant.
544
+ Percentage of improvement (reduction) of serum triglycerides &
545
+ very low -density lipoprotein were more in control group than that
546
+ of yoga group. The reason of this could be that all subjects were
547
+ from same hostel & blinding on the intervention was not possible.
548
+ When yoga group inducted for Yoga intervention, the control group
549
+ were aware of the yoga programme but practical details were not
550
+ conveyed to them. This might have also given them some motivation
551
+ to do regular physical activities because of which improvement was
552
+ observed with their variables also. All 14 adolescents completed the
553
+ intervention, there were no adverse effects noticed during the study.
554
+ However, RCT with larger samples are needed to validate its efficacy
555
+ as a primary intervention.
556
+ Strengths & limitations
557
+ This is a unique study on adolescent obesity with control group.
558
+ It is found that INTEGRATED APPROACH OF YOGA THERAPY
559
+ MODULE has been proved effective in obesity parameters
560
+ management. Further both the groups were belonging to similar age
561
+ limits which leads to reduction of confounding factors. Blind study
562
+ was difficult as participants of both the groups were studying in same
563
+ campus. The food plan was same for both the groups. Current study
564
+ confirms that the one hour INTEGRATED APPROACH OF YOGA
565
+ THERAPY MODULE is an effective alternative in adolescent obesity.
566
+ Larger sample study along with psychological parameters is needed to
567
+ strengthen its efficacy as a primary intervention.
568
+ Conclusion
569
+ Integrated approach of yoga therapy module having 36practices
570
+ for adolescent obesity is effective in management of weight, serum
571
+ triglyceride & very low-density lipoprotein, hip circumference &
572
+ serum cholesterol. Yoga group has improved better than control group
573
+ with INTEGRATED APPROACH OF YOGA THERAPY MODULE.
574
+ This module hasproved efficient in management of adolescent obesity.

+ warranted to evaluate the effects of Shatkriya in health and disease.

39
+ 1. Introduction
40
+ Cleansing practices are part of most indegenous health sys-
41
+ tems, be it Yoga, Naturopathy, Ayurveda, or Chinese Medicine. In
42
+ Yoga, six cleansing practices are described in the Hatha Yoga
43
+ tradition, which are known to balance the constitution of an in-
44
+ dividual. These six cleansing practices in Yoga are known as
45
+ Shatkarma or Shatkriya, which are said to promote health and
46
+ well-being by purifying the whole body. Hatha Yoga Pradipika (ch:
47
+ 2, v. 21 and 22) of Swatmarama recommends the practice Shatk-
48
+ riya prior to practice of pranayama (yogic breath regulation). The
49
+ Shatkriya techniques include dhauti (internal cleansing), basti
50
+ (yogic enema), neti (nasal cleansing), trataka (concentrated ga-
51
+ zing), nauli (abdominal massaging) and kapalabhati (frontal sinus
52
+ cleansing) [1]. Although several health benefits of Shatkriya are
53
+ narrated in HathaYoga texts, there is a lack of comprehensive
54
+ literature on scientific studies in the subject matter. Thus, the
55
+ current review was undertaken to summarize the scientific evi-
56
+ dence on the physiological and therapeutic effects of the
57
+ Shatkriya.
58
+ 1.1. Traditional references for Shatkriya
59
+ There are four major texts of Hatha Yoga tradition viz. Hatha Yoga
60
+ Pradipika, Gheranda Samhita, Shiva Samhita and Hatharatnavali.
61
+ Among them Gheranda samhita and Hatha Yoga Pradipika describe
62
+ the purification of the body, with reference to six variants of the
63
+ cleansing procedures [1,2]. Gheranda Samhita has an elaborate
64
+ description of the sub-types and benefits of the Shatkriya. Hathar-
65
+ atnavali, which is the latest among the Hatha Yoga texts, narrates
66
+ eight variants of cleansing techniques [3]. However, the six cleansing
67
+ techniques described in the Hatha Yoga Pradipika of Swami Swat-
68
+ marama are most popular among the Yoga practitioners. The main
69
+ objective of Shatkriya is to balance the three humours (tridosha) in
70
+ the body, mucus (kapha), bile (pitta) and wind (vata) [1].
71
+ Though there are a few similarities in the cleansing procedures
72
+ described in Yoga and Ayurveda (such as basti and vamana dhauti),

+ the yogic cleansing methods are unique for multiple reasons. The
84

85
+ guidance of Yoga teacher and without administration of any

87
+ 2. Methodology
88
+ A comprehensive literature search in PubMed, PubMed Central,
89
+ and Google Scholar databases was carried out for the keywords
90
+ “shatkriya, shatkarma, dhauti. yogic stomach wash, basti, yogic
91
+ enema, neti, yogic nasal cleansing, nasal irrigation, trataka, yogic
92
+ visual concentration, nauli, yogic abdominal massage, kapalabhati,
93
+ yogic frontal sinus cleansing, high frequency Yoga breathing”. The
94
+ search yielded a total number of 665 references from the year 1976
95
+ till April 2020 for the above-mentioned keywords. Experimental
96
+ and quasi-experimental studies and case reports in English, with
97
+ yogic cleansing techniques as an intervention were included in the
98
+ review. The studies that had combination of Yoga practices were
99
+ excluded. After applying the inclusion and exclusion criteria and
100
+ removing the duplicates, a total of 37 studies were selected for the
101
+ final review. The studies are presented based on the cleansing
102
+ techniques.
103
+ 3. Summary of scientific evidence on yogic cleansing
104
+ techniques
105
+ 3.1. Dhauti
106
+ A literal meaning of dhauti is internal cleansing. Four major
107
+ forms of dhauti kriya as described in the Gheranda Samhita viz. antar
108
+ (internal), danta (teeth), hrid (cardiac) and moola shodhana (puri-
109
+ fication of the anus) [1,2]. The most popular forms of dhauti include
110
+ vamana dhauti, also known as kunjala kriya, vastra dhauti and
111
+ shankha prakshalana. Kunjala kriya includes drinking warm saline
112
+ water and voluntarily inducing vomiting to clear the contents of
113
+ stomach. In vastra dhauti, the practitioner swallows a soft cotton
114
+ cloth of about 2 m length and 4 cm width and removes the same.
115
+ The practice of shankha prakshalana includes drinking warm saline
116
+ water and passing it in the bowels by inducing peristalsis through
117
+ certain postures [1]. It aids in reducing ailments of the digestive
118
+ system like constipation, biliousness, indigestion, chronic gastritis,
119
+ reflux acts. It even helps to reduce accessory organ ailments of
120
+ digestive systems like torpid liver, sluggish pancreas, urinary
121
+ elimination, renal complaints, and dyspeptic condition. Indirectly it
122
+ strengthens the heart and respiratory systems like cough, asthma,
123
+ tonsillitis and teeth problems. It even benefits in arthritis, diabetes,
124
+ and loosening of weight [4].
125
+ 3.1.1. Effects of dhauti on respiratory system
126
+ A study was conducted to assess the effect of kunjala kriya on the
127
+ pulmonary functions in healthy volunteers. The authors found the
128
+ practice to play a role in enhancing pulmonary functions along with
129
+ increased vagal tone. These findings were based on the increase in
130
+ slow vital capacity, forced inspiratory volume along with a reduc-
131
+ tion in expiratory reserve volume and respiratory rate. The findings
132
+ also indicate a possible increase in endurance of the respiratory
133
+ muscles, decreased airway resistance, better emptying of lungs,
134
+ which may play a role in restrictive lung disorders [5].
135
+ 3.1.2. Effect of dhauti on bowel health
136
+ A recent randomized controlled study done on 60 healthy in-
137
+ dividuals, demonstrated beneficial effects of laghu shankha prak-
138
+ shalana in bowel health. Thirty volunteers who received the
139
+ intervention once in a week for 4 weeks demonstrated better scores
140
+ in the Cleveland clinic constipation scale. The control group
141
+ showed no significant change during the follow-up period [6].
142
+ 3.1.3. Effect of dhauti in chronic low back pain
143
+ A self as controlled study was conducted in 40 in-patients,
144
+ randomly assigned to receive laghu shankha prakshalana and back
145
+ pain yogic special technique on specific days. Assessments were
146
+ performed before and immediately after the sessions. Pain and
147
+ disability were assessed using Oswestry disability index, state
148
+ anxiety using the state subscale of Spieldberger’s state and trait
149
+ anxiety inventory, spinal flexibility, and straight leg raising tests
150
+ using Leighton type goniometer and caliper type goniometer
151
+ respectively. Both Yoga sessions were found to beneficial to the
152
+ patients, but the magnitude of change was higher following the
153
+ laghu shankha prakshalana session. Thus, laghu shankha prak-
154
+ shalana practice was found to reduce pain, disability, anxiety, and
155
+ help to increase in flexibility [7].
156
+ 3.1.4. A complication of dhauti
157
+ Practice of dhauti is generally considered safe when it is done
158
+ under the guidance of a teacher. One case study was found to report
159
+ the adverse effect of dhauti during the literature review. A case of
160
+ dental erosion diagnosed using the Tooth Wear Index was reported
161
+ by Meshramkar and Patil (2007) which they had attributed to the
162
+ regular practice of kunjala kriya for 12 years [8].
163
+ Thus, from the limited evidence available on dhauti kriya, it was
164
+ found useful as a therapeutic modality in the management of res-
165
+ piratory and digestive disorders. The practice should be done under
166
+ the guidance of a trained teacher, which may help to avoid possible
167
+ complications. Further large-scale clinical trials are required to
168
+ establish the usefulness of dhauti as therapeutic modality. We have
169
+ summarized the studies on dhauti in Table 1.
170
+ 3.2. Neti (yogic nasal cleansing)
171
+ The practice of Neti is advised in Hatha Yoga to clean the nasal
172
+ passage. In classical reference of Hatha Yoga Pradipka only sutra neti
173
+ is explained however in general four variations of Neti practiced,
174
+ which includes jala (water), sutra (thread), dugdha (milk), and
175
+ ghritha (ghee) [1,9]. The most popular forms of Neti practice are jala
176
+ and sutra neti. In Jala neti, saline warm water is passed from one
177
+ nostril to another using a specially designed pot. The classical
178
+ practice of sutra neti involves inserting a thread in the nostril and
179
+ removing it from the mouth. In modern times instead of thread, a
180
+ sterile catheter is used. Neti removes mucus from nostrils, sinuses
181
+ which helps to allow the air easily without obstruction. This help in
182
+ reducing allergic rhinitis, tonsillitis and to prevent cough, cold and
183
+ tension headache due to eye strain.
184
+ 3.2.1. Use of Neti for rhino-sinusitis
185
+ A study done on 150 subjects with chronic sinusitis assigned
186
+ them in 3 treatment groups: nasal irrigation with a bulb syringe or
187
+ jala neti, or reflexology massage. The follow-up duration was for 2
188
+ weeks. All three groups demonstrated improvement in rhinosinu-
189
+ sitis outcome measures [10]. More than 70 percent of the partici-
190
+ pants wanted to continue practicing nasal irrigation even after
191
+ completion of the study. The study also depicted that the im-
192
+ provements in the symptoms were better in male population.
193
+ Smokers in the study did not show improvement in the symptoms.
194
+ Sinusitis is a common problem among children. Shoseyov et al.
195
+ (1998) conducted a double blind RCT to illustrate the efficacy of
196
+ normal water verses jala neti in children with chronic sinusitis. The
197
+ outcome measures used were cough, nasal secretion and radio-
198
+ logical assessment tools. They found significant improvements in
199
+ four-weeks in the group which used jala neti, when compared to
200
+ P.S. Swathi, B.R. Raghavendra and A.A. Saoji
201
+ Journal of Ayurveda and Integrative Medicine 12 (2021) 206e212
202
+ 207
203
+ normal saline. The effects were sustained for a follow-up period of
204
+ one month after the conclusion of the trial [11].
205
+ A case series was conducted to report effects of jala neti in 10
206
+ cases of sinusitis among children (age range: 3e9 years). The au-
207
+ thors found improvement in the disease-related Quality of life and
208
+ in symptom management [12].
209
+ An early study assessed the inflammatory markers in thirty
210
+ symptomatic patients with active perennial allergic rhinitis. The
211
+ three interventions compared were nasal heated water particles
212
+ at 43 degrees C for 20 min, heated molecular water vapor at 41C
213
+ for 20 min, and simple jala neti at 39C solution for 15 min at
214
+ weekly intervals. Nasal washes were done before and immedi-
215
+ ately after the treatments, at 30 min, 2 h, 4 h, 6 h. Inflammatory
216
+ mediators such as histamine, prostaglandin D2, leukotriene
217
+ C4 concentrations were assessed using a competitive radioim-
218
+ munoassay.
219
+ Inflammatory
220
+ mediators
221
+ in
222
+ nasal
223
+ secretions
224
+ decreased substantially after jala neti. It reduced histamine for a
225
+ period of 6 h, after a single 15 min treatment, illustrating the
226
+ beneficial effect of jala neti in reducing allergic response and
227
+ inflammation [13].
228
+ A study (SNIFS Trial) assessing the efficacy of self-management
229
+ tools for recurrent sinusitis compared jala neti with steam inhala-
230
+ tion. The investigators of the study followed 32 participants for a
231
+ period of six months. They concluded both interventions were
232
+ acceptable to the patients, but jala neti was found to be effective in
233
+ symptom management [14]. A large scale RCT involving 871 par-
234
+ ticipants indicated that jala neti being better in managing symp-
235
+ toms of rhino-sinusitis and being acceptable to participants than
236
+ steam inhalation [15].
237
+ A randomized control trial with seventy-six subjects followed
238
+ patients with sinusits for a period of six months. The investigators
239
+ found improved quality of life, reduced symptoms, and need for
240
+ medications in patients who performed jala neti daily for six-
241
+ months [16].
242
+ 3.2.2. Neti for post-irradiation rhinosinusitis in nasopharyngeal
243
+ carcinoma
244
+ Sinusitis and nasopharyngeal irritation are common following
245
+ radiotherapy for nasopharyngeal carcinoma. A five-year follow-up
246
+ study demonstrated that long term nasal irrigation helped in
247
+ improving quality of life (QoL) of patients affected with nasopha-
248
+ ryngeal carcinoma within a one year of intervention there was a
249
+ relief in nasal symptoms [17]. Similar observation of improved
250
+ quality of life and reduced symptoms were observed in a trial
251
+ involving 107 nasopharyngeal carcinoma patients after irradiation.
252
+ The follow-up duration for the study was six months [18].
253
+ 3.2.3. Complication of Sutra neti
254
+ There was a case of 67 year old man presenting with change of
255
+ voice, loss of sensation of smell, nose blockage and mouth
256
+ breathing after regular practice of Sutra neti. He had to undergo a
257
+ controlled ablation for release of the nostrils. The investigators
258
+ suggested to avoid vigorous practice of sutra neti [19].
259
+ Thus, Neti, being one of the easiest cleansing procedures in Yoga,
260
+ plays advantageous role in management of rhino-sinusitis. A case
261
+ study also indicates beneficial effect of sutra neti on obstructive
262
+ sleep apnea and snoring. The results indicate that the traditional
263
+ explanation from Hatha Yoga Pradipika stating neti can help to cure
264
+ disease above the throat appear to be supported with scientific
265
+ evidence. The evidence based effects of neti kriya are summarized
266
+ in Table 2.
267
+ 3.3. Trataka (yogic visual concentration)
268
+ The practice of trataka involves concentrated gazing on a small
269
+ object (usually a candle flame). The classical explanation of the
270
+ practice involves gazing at an object without blinking the eyes, till
271
+ tears roll out. The technique is said to reduce the eye disorders and
272
+ to reduce the laziness [1]. The scientific studies on Trataka used
273
+ cognitive functions and vision as their outcome measures.
274
+ 3.3.1. Effect of trataka on attention and cognition
275
+ A self as control study assessed effect of trataka on critical
276
+ flicker fusion (CFF). CFF is defined as the frequency at which a
277
+ flickering stimulus perceived to be continuous. Thirty subjects
278
+ were recruited for the study who were conditioned for the prac-
279
+ tice
280
+ through
281
+ five
282
+ sessions
283
+ on
284
+ different
285
+ days
286
+ before
287
+ the
288
+ commencement of assessments. Subjects were assessed individ-
289
+ ually for CFF immediately before and after the trataka or control
290
+ sessions. The trataka session involved eye exercise followed by
291
+ gazing at the candle flame whereas control session had only eye
292
+ exercise. The CFF was assessed with increasing and decreasing
293
+ frequencies. The trataka group shown a significant increase in CFF,
294
+ and there was a nonsignificant reduction in CFF following the
295
+ control session [21].

378
+ intervention compared to the baseline. This study indicates a

381
+ A study assessed the immediate effect of trataka on heart rate
382
+ variability (HRV) and breathing rate following two sessions on two
383
+ different days. The investigators found an increased in vagal tone
384
+ following trataka depicted by a decrease in heart rate and breath
385
+ rate, low frequency component of HRV and increase in high fre-
386
+ quency component. No changes were observed following the con-
387
+ trol session [24].
388
+ 3.3.3. Clinical trials on trataka and eye disorders
389
+ A study assessing outcomes of ametropia and presbyopia
390
+ compared the effects of two forms of eye exercises viz. Bates
391
+ method and trataka. The investigators reported subjective im-
392
+ provements in the vision without any change in objective assess-
393
+ ment tools following both forms of eye exercises [25,26]. Table 3
394
+ illustrates the studies on trataka. Although, traditional texts quote
395
+ trataka can be used to treat eye disorders, but not many studies
396
+ have evaluated the role of trataka in eye disorders. The limited
397
+ evidence does not support role of trataka in eye disorders, thus
398
+ there is scope for further scientific evaluation in the subject area
399
+ The studies also demonstrat enhanced cognitive functions and
400
+ autonomic relaxation immediately following the practice. Thus,
401
+ there is a need to explore long term effects of trataka in physio-
402
+ logical and clinical settings.

404
+ Kapalabhati is a combination of two syllables, kapala means
405
+ forehead and bhati means shining. The practice of kapalabhati
406
+ involves breathing out at a rapid pace (~1e2 Hz) by flapping the
407
+ abdomen. Classical texts indicate beneficial role of Kapalabhati in
408
+ respiratory disorders [1] It is also known as high frequency Yoga

553
+ to
554
+ practice
555
+ of
556
+ pranayama
557
+ (yogic
558
+ breathing practices). Some masters categorize the practice of
559
+ kapalabhati as one of the pranayama itself. However, the practice
560
+ is classified as one of the Shatkriya as per the traditional Yoga
561
+ texts [27].
562
+ 3.4.1. Effect of kapalabhati on metabolism
563
+ One of the earliest studies on kapalabhati showed a decrease in
564
+ blood urea with an increase in creatinine and tyrosine following
565
+ one minute of practice in twelve healthy subjects. These changes
566
+ were attributed to a possible promotion of decarboxylation and
567
+ oxidation [28].
568
+ 3.4.2. Effect of kapalabhati on respiratory and cardiovascular
569
+ changes
570
+ Stancak and colleagues conducted a group of experiments to
571
+ determine physiological changes associated with kapalabhati as
572
+ early as in 1991. Their experiments demonstrated reduction in
573
+ baroreflex sensitivity and vagal tone, associated with increase in
574
+ blood pressure and heart rate following kapalabhati. They could
575
+ also demonstrate slower brain waves in the EEG topography which
576
+ were attributed to the subjective relaxation in the participants
577
+ [29e31].
578
+ Series of studies were conducted by Telles et al. on the effects of
579
+ kapalabhati. They found kapalabhati improves cognitive perfor-
580
+ mance and attention assessed through event related potentials
581
+ [32], associated with decreased anxiety [33]. Similar positive out-
582
+ comes were found with motor performance [34] and finger dex-
583
+ terity [35] and spatial and working memory tasks [36] following
584
+ Kapalabhati. They also observed sympathetic arousal [37,38], and
585
+ metabolic activation [39], during kapalabhati however, the practice
586
+ does not cause increase in the prefrontal cerebral circulation [40].
587
+ A study conducted on effect of kapalabhati on cognitive func-
588
+ tions demonstrated improvements in the cognitive tasks [41].
589
+ Transcranial doppler was used to assess the cerebral blood flow
590
+ changes during practice of kapalabhati. There was a reduction noted
591
+ in the end diastolic velocity and mean flow velocity indicating a
592
+ decrease in cerebral blood flow. Such change could be due to
593
+ reduction of partial pressure of CO2 during the practice which in-
594
+ volves breathing at a high frequency [42].
595
+ An RCT performed on 60 mild to moderate asthma patients
596
+ demonstrated 10 min of practice of kapalabhati can enhance the
597
+ forced vital capacity, forced expiratory volume in one second and
598
+ their ratio. These finding indicate a possible role of kapalabhati in
599
+ management of bronchial asthma [43].
600
+ 3.4.3. The complication of kapalabhati
601
+ A case report presented a 29-year-old healthy woman, who
602
+ developed the spontaneous pneumothorax caused due to extreme
603
+ practice of kapalabhati. The investigators attributed such compli-
604
+ cation to pushing the practice to physiological extreme limits [44].
605
+ Thus, the studies on kapalabhati illustrate the beneficial effects
606
+ of the technique in enhancing cognitive and respiratory functions
607
+ and leading to a state of physiological arousal. Such changes can be
608
+ used in clinical situations such as bronchial asthma. However, one
609
+ should be careful not to strain while performing the practice of
610
+ kapalabhati, which may also lead to complications. The evidence
611
+ summary on kapalabhati is summarized in Table S1.
612
+ 3.5. Basti (yogic enema)
613
+ There are two forms of Basti described in Hatha Yoga, jala (wa-
614
+ ter) and sthala (dry). Both basti practices involve the cleansing of
615
+ the colon. Swami Swatmarama considers the practice of basti
616
+ beneficial for balancing tridosha and dhatus and to purify mind and
617
+ senses [1]. According to sage Gherenda, basti reduces the disorders
618
+ of vata and is beneficial in urinary and digestive problems. It is also
619
+ known to improve digestion [2].

+ 3.6. Nauli (yogic abdominal massaging)
715
+ Nauli is a practice of contracting and isolating the rectus
716
+ abdominis muscle and churning the abdominal muscles. There are
717
+ three variations based on the position of isolation of the muscles,
718
+ namely dakshina nauli (right), vama nauli (left), madhyama (center).
719
+ This practice is said to strengthen the secretion of gastric juice
720
+ including endocrine and exocrine functions of the pancreas [1,9].
721
+ Since the practices of basti and nauli are considered to be an
722
+ advance practice, we could not find any scientific study on the
723
+ practice of nauli during our literature review.
724
+ 4. Conclusion
725
+ The practice of shatkriya or shatkarma is recommended in the
726
+ Hathayoga tradition. Studies exploring the effects of four out of six
727
+ cleansing procedures were found in physiological as well as clinical
728
+ settings. No studies were available on basti and nauli which could
729
+ be due to the difficult nature of the practice. The practice of dhauti
730
+ was found to enhance respiratory functions and was useful in
731
+ digestive disorders. Nasal cleansing, neti was particularly found
732
+ beneficial in managing the rhinosinusitis in age groups ranging
733
+ from children to adults. Although trataka practice was found to
734
+ enhance cognition and bring a state of relaxation, but there was no
735
+ evidence supporting its role in eye disorders. Kapalabhati was the
736
+ most studies among the Shatkriya practices. The ranges of studies
737
+ on kapalabhati included assessing the neurocognitive assessments,
738
+ autonomic, and metabolic activity. The practice appears to have a
739
+ beneficial role in the activation of sympathetic nervous system,
740
+ enhances cognition, and improves overall metabolism. It was also
741
+ found to enhance the respiratory functions in patients with asthma.
742
+ Single case reports (one each) were also found for practices of
743
+ dhauti, neti and kapalabhati and it was attributed to pushing the
744
+ body to the physiological extreme.
745
+ This literature review was limited to online free databases only
746
+ and due to the keywords chosen. Although we tried, including a
747
+ variety of key-words related to shatkriya, there may have been
748
+ studies that were missed in the current review because of exclusion
749
+ through the keywords and databases.
750
+ The beneficial role of shatkriyas narrated in both traditional texts
751
+ and evident from the small body of empirical work warrants
752
+ further rigorous scientific exploration. From the available literature,
753
+ we found the practice of yogic cleansing technique safe, when
754
+ practiced under the guidance of a trained teacher and has a po-
755
+ tential role in health and disease.
