1.  Iyengar Yoga for Adolescents and Young Adults With Irritable Bowel Syndrome 
Irritable bowel syndrome (IBS) is a chronic, disabling condition that greatly compromises patient functioning. The aim of this study was to assess the impact of a 6-week twice per week Iyengar yoga (IY) program on IBS symptoms in adolescents and young adults (YA) with IBS compared with a usual-care waitlist control group.
Assessments of symptoms, global improvement, pain, health-related quality of life, psychological distress, functional disability, fatigue, and sleep were collected pre- and posttreatment. Weekly ratings of pain, IBS symptoms, and global improvement were also recorded until 2-month follow-up. A total of 51 participants completed the intervention (yoga = 29; usual-care waitlist = 22).
Baseline attrition was 24%. On average, the yoga group attended 75% of classes. Analyses were divided by age group. Relative to controls, adolescents (14–17 years) assigned to yoga reported significantly improved physical functioning, whereas YA (18–26 years) assigned to yoga reported significantly improved IBS symptoms, global improvement, disability, psychological distress, sleep quality, and fatigue. Although abdominal pain intensity was statistically unchanged, 44% of adolescents and 46% of YA reported a minimally clinically significant reduction in pain following yoga, and one-third of YA reported clinically significant levels of global symptom improvement. Analysis of the uncontrolled effects and maintenance of treatment effects for adolescents revealed global improvement immediately post-yoga that was not maintained at follow-up. For YA, global improvement, worst pain, constipation, and nausea were significantly improved postyoga, but only global improvement, worst pain, and nausea maintained at the 2-month follow-up.
The findings suggest that a brief IY intervention is a feasible and safe adjunctive treatment for young people with IBS, leading to benefits in a number of IBS-specific and general functioning domains for YA. The age-specific results suggest that yoga interventions may be most fruitful when developmentally tailored.

2.  Impact of Iyengar yoga on quality of life in young women with rheumatoid arthritis 
The Clinical journal of pain  2013;29(11):988-997.
Rheumatoid arthritis (RA) is a chronic, disabling disease that can greatly compromise health related quality of life (HRQOL). The aim of this study was to assess the impact of a 6-week twice/week Iyengar yoga (IY) program on HRQOL of young adults with RA compared to a usual-care waitlist control group.
The program was designed to improve the primary outcome of HRQOL including pain, as well as disability and psychological functioning in patients. Assessments were collected pre, post, and at 2-months following treatment. Weekly ratings of anxiety, depression, pain and sleep were also recorded. A total of 26 participants completed the intervention (yoga = 11; usual care waitlist = 15). All participants were female (mean age =28 years).
Overall attrition was low at 15%. On average, women in the yoga group attended 96% of the yoga classes. No adverse events were reported. Relative to the usual-care waitlist, women assigned to the yoga program showed significantly greater improvement on standardized measures of HRQOL, pain disability, general health, mood, fatigue, acceptance of chronic pain and self-efficacy regarding pain at post treatment. Almost half of the yoga group reported clinically meaningful symptom improvement. Analysis of the uncontrolled effects and maintenance of treatment effects showed improvements in HRQOL general health, pain disability and weekly ratings of pain, anxiety and depression that maintained at follow-up.
The findings suggest a brief IY intervention is a feasible and safe adjunctive treatment for young people with RA, leading to health related quality of life (HRQOL), pain disability, fatigue, and mood benefits. Moreover, improvements in quality of life, pain disability and mood persisted at the 2-month follow-up.

3.  Effectiveness of Iyengar yoga in treating spinal (back and neck) pain: A systematic review 
Considerable amount of money spent in health care is used for treatments of lifestyle related, chronic health conditions, which come from behaviors that contribute to morbidity and mortality of the population. Back and neck pain are two of the most common musculoskeletal problems in modern society that have significant cost in health care. Yoga, as a branch of complementary alternative medicine, has emerged and is showing to be an effective treatment against nonspecific spinal pain. Recent studies have shown positive outcome of yoga in general on reducing pain and functional disability of the spine. The objective of this study is to conduct a systematic review of the existing research within Iyengar yoga method and its effectiveness on relieving back and neck pain (defined as spinal pain). Database research form the following sources (Cochrane library, NCBI PubMed, the Clinical Trial Registry of the Indian Council of Medical Research, Google Scholar, EMBASE, CINAHL, and PsychINFO) demonstrated inclusion and exclusion criteria that selected only Iyengar yoga interventions, which in turn, identified six randomized control trials dedicated to compare the effectiveness of yoga for back and neck pain versus other care. The difference between the groups on the postintervention pain or functional disability intensity assessment was, in all six studies, favoring the yoga group, which projected a decrease in back and neck pain. Overall six studies with 570 patients showed, that Iyengar yoga is an effective means for both back and neck pain in comparison to control groups. This systematic review found strong evidence for short-term effectiveness, but little evidence for long-term effectiveness of yoga for chronic spine pain in the patient-centered outcomes.

4.  Protocol for a randomized controlled study of Iyengar yoga for youth with irritable bowel syndrome 
Trials  2011;12:15.
Irritable bowel syndrome affects as many as 14% of high school-aged students. Symptoms include discomfort in the abdomen, along with diarrhea and/or constipation and other gastroenterological symptoms that can significantly impact quality of life and daily functioning. Emotional stress appears to exacerbate irritable bowel syndrome symptoms suggesting that mind-body interventions reducing arousal may prove beneficial. For many sufferers, symptoms can be traced to childhood and adolescence, making the early manifestation of irritable bowel syndrome important to understand. The current study will focus on young people aged 14-26 years with irritable bowel syndrome. The study will test the potential benefits of Iyengar yoga on clinical symptoms, psychospiritual functioning and visceral sensitivity. Yoga is thought to bring physical, psychological and spiritual benefits to practitioners and has been associated with reduced stress and pain. Through its focus on restoration and use of props, Iyengar yoga is especially designed to decrease arousal and promote psychospiritual resources in physically compromised individuals. An extensive and standardized teacher-training program support Iyengar yoga's reliability and safety. It is hypothesized that yoga will be feasible with less than 20% attrition; and the yoga group will demonstrate significantly improved outcomes compared to controls, with physiological and psychospiritual mechanisms contributing to improvements.
Sixty irritable bowel syndrome patients aged 14-26 will be randomly assigned to a standardized 6-week twice weekly Iyengar yoga group-based program or a wait-list usual care control group. The groups will be compared on the primary clinical outcomes of irritable bowel syndrome symptoms, quality of life and global improvement at post-treatment and 2-month follow-up. Secondary outcomes will include visceral pain sensitivity assessed with a standardized laboratory task (water load task), functional disability and psychospiritual variables including catastrophizing, self-efficacy, mood, acceptance and mindfulness. Mechanisms of action involved in the proposed beneficial effects of yoga upon clinical outcomes will be explored, and include the mediating effects of visceral sensitivity, increased psychospiritual resources, regulated autonomic nervous system responses and regulated hormonal stress response assessed via salivary cortisol.

5.  Evaluation of the Effectiveness and Efficacy of Iyengar Yoga Therapy on Chronic Low Back Pain* 
Spine  2009;34(19):2066-2076.
Study Design
The effectiveness and efficacy of Iyengar yoga for chronic low back pain (CLBP) were assessed with intention-to-treat and per-protocol analysis. Ninety subjects were randomized to a yoga (n=43) or control group (n=47) receiving standard medical care (SMC). Participants were followed 6 months after completion of the intervention.
This study aimed to evaluate Iyengar yoga therapy on chronic low back pain. Yoga subjects were hypothesized to report greater reductions in functional disability, pain intensity, depression, and pain medication usage than controls.
Summary of Background Data
CLBP is a musculoskeletal disorder with public health and economic impact. Pilot studies of yoga and back pain have reported significant changes in clinically important outcomes.
Subjects were recruited through self-referral and health professional referrals according to explicit inclusion/exclusion criteria. Yoga subjects participated in 24 weeks of biweekly yoga classes designed for CLBP. Outcomes were assessed at 12 (midway), 24 (immediately after) and 48 weeks (6 month follow-up) after the start of the intervention using the Oswestry Disability Questionnaire, a Visual Analog Scale, the Beck Depression Inventory, and a pain medication-usage questionnaire.
Using intention-to-treat analysis with repeated measures ANOVA (group × time), significantly greater reductions in functional disability and pain intensity were observed in the yoga group when compared to the control group at 24 weeks. A significantly greater proportion of yoga subjects also reported clinical improvements at both 12 and 24 weeks. In addition, depression was significantly lower in yoga subjects. Furthermore, while a reduction in pain medication occurred, this was comparable in both groups. When results were analyzed using per-protocol analysis, improvements were observed for all outcomes in the yoga group, including a greater trend for reduced pain medication usage. Although slightly less than at 24 weeks, the yoga group had statistically significant reductions in functional disability, pain intensity and depression compared to SMC 6-months post-intervention.
Yoga improves functional disability, pain intensity, and depression in adults with CLBP. There was also a clinically important trend for the yoga group to reduce their pain medication usage compared to the control group.

6.  Comparison of yoga versus stretching for chronic low back pain: protocol for the Yoga Exercise Self-care (YES) trial 
Trials  2010;11:36.
Back pain, one of the most prevalent conditions afflicting American adults, is the leading reason for using complementary and alternative medicine (CAM) therapies. Yoga is an increasingly popular "mind-body" CAM therapy often used for relieving back pain and several small studies have found yoga effective for this condition. This study will assess whether yoga is effective for treating chronic low back pain compared with self care and exercise and will explore the mechanisms responsible for any observed benefits.
A total of 210 participants with low back pain lasting at least 3 months will be recruited from primary care clinics of a large healthcare system based in Seattle. They will be randomized in a 2:2:1 ratio to receive 12 weekly yoga classes, 12 weekly conventional therapeutic exercise classes of comparable physical exertion, or a self-care book. Interviewers masked to participants' treatment group will assess outcomes at baseline and 6, 12 and 26 weeks after randomization. Primary outcomes will be back-related dysfunction and symptom bothersomeness. In addition, data will be collected on physical measurements (e.g., flexion) at baseline and 12 weeks and saliva samples will be obtained at baseline, 6 and 12 weeks. Information will be collected on specific physical, psychological, and physiological factors to allow exploration of possible mechanisms of action through which yoga could relieve back pain and dysfunction. The effectiveness of yoga will be assessed using analysis of covariance (using general estimating equations - GEE) within an intention-to-treat context. If yoga is found effective, further analyses will explore whether yoga's benefits are attributable to physical, psychological and/or physiological factors.
This study will provide the clearest evidence to date about the value of yoga as a therapeutic option for treating chronic back pain, and if the results are positive, will help focus future, more in-depth, research on the most promising potential mechanisms of action identified by this study.

7.  A randomized controlled trial examining Iyengar yoga for young adults with rheumatoid arthritis: a study protocol 
Trials  2011;12:19.
Rheumatoid arthritis is a chronic, disabling disease that can compromise mobility, daily functioning, and health-related quality of life, especially in older adolescents and young adults. In this project, we will compare a standardized Iyengar yoga program for young people with rheumatoid arthritis to a standard care wait-list control condition.
Seventy rheumatoid arthritis patients aged 16-35 years will be randomized into either the 6-week Iyengar yoga program (12 - 1.5 hour sessions twice weekly) or the 6-week wait-list control condition. A 20% attrition rate is anticipated. The wait-list group will receive the yoga program following completion of the first arm of the study. We will collect data quantitatively, using questionnaires and markers of disease activity, and qualitatively using semi-structured interviews. Assessments include standardized measures of general and arthritis-specific function, pain, mood, and health-related quality of life, as well as qualitative interviews, blood pressure/resting heart rate measurements, a medical exam and the assessment of pro-inflammatory cytokines. Data will be collected three times: before treatment, post-treatment, and two months following the treatment.
Results from this study will provide critical data on non-pharmacologic methods for enhancing function in rheumatoid arthritis patients. In particular, results will shed light on the feasibility and potential efficacy of a novel intervention for rheumatoid arthritis symptoms, paving the way for a larger clinical trial.

8.  Yoga Therapy Decreases Dyspnea-Related Distress and Improves Functional Performance in People with Chronic Obstructive Pulmonary Disease: A Pilot Study 
There has been limited study of yoga training as a complementary exercise strategy to manage the symptom of dyspnea in patients with chronic obstructive pulmonary disease (COPD).
The primary purpose of this pilot study was to evaluate a yoga program for its safety, feasibility, and efficacy for decreasing dyspnea intensity (DI) and dyspnea-related distress (DD) in older adults with COPD.
Clinically stable patients with COPD (n = 29; age 69.9 ± 9.5; forced expiratory volume in 1 second (FEV1) 47.7 ± 15.6% predicted; female = 21) were randomized to a 12-week yoga program specifically designed for people with COPD or usual-care control (UC). The twice-weekly yoga program included asanas (yoga postures) and visama vritti pranayama (timed breathing). Safety measure outcomes included heart rate, oxygen saturation, dyspnea, and pain. Feasibility was measured by patient-reported enjoyment, difficulty, and adherence to yoga sessions. At baseline and at 12 weeks, DI and DD were measured during incremental cycle ergometry and a 6-minute walk (6MW) test. Secondary efficacy outcomes included physical performance, psychologic well-being, and health-related quality of life (HRQoL).
Yoga training was safe and feasible for patients with COPD. While yoga training had only small effects on DI after the 6MW test (effect size [ES], 0.20; p = 0.60), there were greater reductions in DD in the yoga group compared to UC (ES, 0.67; p = 0.08). Yoga training also improved 6MW distance (+71.7 ± 21.8 feet versus −27.6 ± 36.2 feet; ES = 0.78, p = 0.04) and self-reported functional performance (ES = 0.79, p = 0.04) compared to UC. There were small positive changes in muscle strength and HRQoL.
Elderly patients with COPD participated safely in a 12-week yoga program especially designed for patients with this chronic illness. After the program, the subjects tolerated more activity with less DD and improved their functional performance. These findings need to be confirmed in a larger, more sufficiently powered efficacy study.

10.  Impact and Outcomes of an Iyengar Yoga Program in a Cancer Centre 
Current Oncology  2008;15(Suppl 2):s109.es72-s109.es78.
Individuals have increasingly sought complementary therapies to enhance health and well-being during cancer, although little evidence of their effect is available.
We investigated how an Iyengar yoga program affects the self-identified worst symptom in a group of participants. whether quality of life, spiritual well-being, and mood disturbance change over the Iyengar yoga program and at 6 weeks after the program. how, from a participant’s perspective, the Iyengar yoga program complements conventional cancer treatment.
Patients and Methods
This pre–post instrumental collective case study used a mixed methods design and was conducted at a private Iyengar yoga studio. The sample consisted of 24 volunteers (23 women, 1 man; 88% Caucasian; mean age: 49 years) who were currently on treatment or who had been treated for cancer within the previous 6 months, and who participated in ten 90-minute weekly Iyengar yoga classes.
The main outcome measures were most-bothersome symptom (Measure Your Medical Outcome Profile 2 instrument), quality of life and spiritual well-being (Functional Assessment of Chronic Illness Therapy–General subscale and Spiritual subscale), and mood disturbance (Profile of Mood States–Short Form). Participant perspectives were obtained in qualitative interviews.
Statistically significant improvements were reported in most-bothersome symptom (t(23) = 5.242; p < 0.001), quality of life (F(2,46) = 14.5; p < 0.001), spiritual well-being (F(2,46) = 14.4; p < 0.001), and mood disturbance (F(2,46) = 10.8; p < 0.001) during the program. At follow-up, quality of life (t(21) = −3.7; p = 0.001) and mood disturbance (t(21) = 2.4; p = 0.025) significantly improved over time. Categorical aggregation of the interview data showed that participants felt the program provided them with various benefits not included on the outcomes questionnaires.
Over the course of the Iyengar Yoga for Cancer program, participants reported an improvement in overall well-being. The program was also found to present participants with a holistic approach to care and to provide tools to effectively manage the demands of living with cancer and its treatment.

11.  Changes in pain intensity and health related quality of life with Iyengar yoga in nonspecific chronic low back pain: A randomized controlled study 
International Journal of Yoga  2014;7(1):48-53.
Nonspecific chronic low back (nCLBP) pain is prevalent among adult population and often leads to functional limitations, psychological symptoms, lower quality of life (QOL), and higher healthcare costs. The purpose of this study was to determine the efficacy of Iyengar yoga therapy on pain intensity and health related quality of life (HRQOL) with nCLBP.
Aim of the Study:
To compare the effect of Iyengar yoga therapy and conventional exercise therapy on pain intensity and HRQOL in nonspecific chronic low back pain.
Materials and Methods:
Experimental study with random sampling technique.
Sixty subjects who fulfilled the selection criteria were randomly assigned to Iyengar yoga (yoga group, n = 30) and control group (exercise group, n = 30). Participants completed low back pain evaluation form and HRQOL-4 questionnaire before their intervention and again 4 weeks and 6 month later. Yoga group underwent 29 yogic postures training and exercise group had undergone general exercise program for 4 weeks.
Repeated measures analysis of variance (ANOVA) was used to analyze group differences over time, while controlling for baseline differences.
Patients in both groups experienced significant reduction in pain and improvement in HRQOL. In visual analogue scale (VAS) yoga group showed reduction of 72.81% (P = 0.001) as compared to exercise group 42.50% (P = 0.001). In HRQOL, yoga group showed reduction of 86.99% (P = 0.001) as compared to exercise group 67.66% (P = 0.001).
These results suggest that Iyengar yoga provides better improvement in pain reduction and improvement in HRQOL in nonspecific chronic back pain than general exercise.

12.  A pilot study of yoga as self-care for arthritis in minority communities 
While arthritis is the most common cause of disability, non-Hispanic blacks and Hispanics experience worse arthritis impact despite having the same or lower prevalence of arthritis compared to non-Hispanic whites. People with arthritis who exercise regularly have less pain, more energy, and improved sleep, yet arthritis is one of the most common reasons for limiting physical activity. Mind-body interventions, such as yoga, that teach stress management along with physical activity may be well suited for investigation in both osteoarthritis and rheumatoid arthritis. Yoga users are predominantly white, female, and college educated. There are few studies that examine yoga in minority populations; none address arthritis. This paper presents a study protocol examining the feasibility and acceptability of providing yoga to an urban, minority population with arthritis.
In this ongoing pilot study, a convenience sample of 20 minority adults diagnosed with either osteoarthritis or rheumatoid arthritis undergo an 8-week program of yoga classes. It is believed that by attending yoga classes designed for patients with arthritis, with racially concordant instructors; acceptability of yoga as an adjunct to standard arthritis treatment and self-care will be enhanced. Self-care is defined as adopting behaviors that improve physical and mental well-being. This concept is quantified through collecting patient-reported outcome measures related to spiritual growth, health responsibility, interpersonal relations, and stress management. Additional measures collected during this study include: physical function, anxiety/depression, fatigue, sleep disturbance, social roles, and pain; as well as baseline demographic and clinical data. Field notes, quantitative and qualitative data regarding feasibility and acceptability are also collected. Acceptability is determined by response/retention rates, positive qualitative data, and continuing yoga practice after three months.
There are a number of challenges in recruiting and retaining participants from a community clinic serving minority populations. Adopting behaviors that improve well-being and quality of life include those that integrate mental health (mind) and physical health (body). Few studies have examined offering integrative modalities to this population. This pilot was undertaken to quantify measures of feasibility and acceptability that will be useful when evaluating future plans for expanding the study of yoga in urban, minority populations with arthritis.

13.  “Now I see a brighter day”: expectations and perceived benefits of an Iyengar yoga intervention for young patients with rheumatoid arthritis 
Rheumatoid arthritis (RA) is a chronic disease characterized by inflammation of joints and associated fatigue, deteriorated range of motion, and impaired psychosocial functioning. Young adults with RA are at a particular risk for compromised health-related quality of life, and there is a need for safe, effective complementary treatment in addition to traditional medical approaches. The aim of the present study was to use face-to-face participant interviews, conducted before and after an Iyengar yoga (IY) program, to examine mechanisms through which yoga may be beneficial to young adults with RA.
This pilot study utilized a single-arm design where all participants received the intervention. Classes were taught twice per week (1.5 hours each) for 6 weeks by an IY teacher qualified in therapeutics. Interview themes included participants’ baseline expectations about yoga and viewpoints as to how their functioning had been impacted by the IY intervention were examined. Five young adults with RA aged 24–31 years (mean = 28; 80% female) completed the yoga intervention. Participants consistently reported that yoga helped with energy, relaxation and mood and they discussed perceived mechanisms for how yoga impacted well-being. Mechanisms included physical changes such as range of motion and physiological awareness, and psychospiritual developments such as acceptance, coping, self-efficacy and mindfulness. Though the study is limited, participants’ responses provide compelling evidence that IY for RA patients is an intervention worthy of further exploration. The mechanisms and outcomes reported by participants support a biopsychosocial model, which proposes that yoga benefits patients through both physiological and psychospiritual changes.

14.  Testing the efficacy of Yoga as a Complementary Therapy for Smoking Cessation: Design and Methods of the BreathEasy trial 
Contemporary clinical trials  2014;38(2):321-332.
Smokers trying to quit encounter many challenges including nicotine withdrawal symptoms, cigarette craving, increased stress and negative mood and concern regarding weight gain. These phenomena make it difficult to successfully quit smoking. Studies in non-smoking populations show that yoga reduces stress and negative mood and improves weight control. By increasing mindfulness we anticipate that yoga may also improve smokers’ ability to cope with the negative symptoms associated with quitting. Yoga may also improve cognitive deliberation which is needed to make effective choices and avoid smoking in tempting situations.
The BreathEasy study is a rigorous, randomized controlled clinical trial examining the efficacy of Iyengar yoga as a complementary therapy to cognitive-behavioral therapy for smoking cessation. All participants are given an 8-week program of smoking cessation classes, and are randomized to either twice weekly yoga (Yoga) or twice-weekly health and wellness classes which serve as a control for contact and participant burden (CTL).
Assessments are conducted at baseline, 8 weeks, 3, 6, and 12 months follow up. The primary outcome is prolonged abstinence using an intention-to-treat approach. Multiple internal and external audits using blind data collection are employed to ensure treatment fidelity and reliability of study results. To understand why yoga may be more effective than CTL, we will examine mechanisms of action (i.e., mediators) underlying intervention efficacy. We will examine maintenance of yoga practice and smoking status at each follow up. Focus groups and interviews will be used to enrich our understanding of the relationship of yoga practice and smoking abstinence.

15.  Yoga and pilates in the management of low back pain 
Many interventions for the management of low back pain exist, however most have modest efficacy at best, and there are few with clearly demonstrated benefits once pain becomes chronic. Therapeutic exercise, on the other hand, does appear to have significant benefits for managing patients with chronic low back pain (CLBP) in terms of decreasing pain and improving function. In addition, because chronic pain is complex and does not fit a simple model, there have also been numerous trials investigating and demonstrating the efficacy of multidisciplinary pain programs for CLBP. It follows that interventions that treat more than one aspect of LBP would have significant benefits for this patient population. Yoga and Pilates which have, both been gaining in popularity over the last decade are two mind–body exercise interventions that address both the physical and mental aspects of pain with core strengthening, flexibility, and relaxation. There has been a slow evolution of these nontraditional exercise regimens into treatment paradigms for LBP, although few studies examining their effects have been published. The following article will focus on the scientific and theoretical basis of using yoga and Pilates in the management of CLBP.

16.  18D. Yoga Promotes Relaxation in Children and Adolescents With Recurrent Headache 
Focus Areas: Integrative Approaches to Care, Supporting Behavioral Change, Alleviating Pain
Recurrent headaches are prevalent in children and adolescents. Up to 89% of these individuals identify stress as a trigger. Yoga offers a complementary and alternative method for this population who often lacks effective relaxation tools for stress relief. This presentation describes the yoga group offered as part of the Integrative Headache Clinic (IHC) at Children's Hospital Colorado. One of the objectives is to determine the effect of the yoga group for children and adolescents with recurrent headaches on pain and relaxation scores.
Over the course of 18 months (January 2011 to June 2012), a retrospective chart review was conducted of 40 children and adolescents with an average age of 15 years, 62.5% of whom were female. During the first hour of clinic, every individual takes part in a 50-minute group yoga session consisting of 10 asanas that promote relaxation and pain relief. Before and after yoga group, participants rate their level of pain and relaxation on a scale from 0 to 10 (with 0 being no pain or relaxation and 10 being maximum pain or relaxation). The average “before yoga” pain score was 3.7 ( /- 3.0) and “after yoga” pain score was 3.4 ( /-3.1) (P=.0672), representing a decrease in pain. The average “before yoga” relaxation score was 5.2 ( /- 2.3) and “after yoga” relaxation score was 7.5 ( /-1.9) (P<.0001), representing a statistically significant increase in relaxation.
Group yoga is effective in promoting relaxation in children and adolescents with recurrent headache. Yoga may offer an adjunct to common pharmaceutical options for headache management for children and adolescents.

17.  A pragmatic multi-centred randomised controlled trial of yoga for chronic low back pain: Trial protocol 
A systematic review revealed three small randomised controlled trials of yoga for low back pain, all of which showed effects on back pain that favoured the yoga group. To build on these studies a larger trial, with longer term follow-up, and a number of different yoga teachers delivering the intervention is required. This study protocol describes the details of a randomised controlled trial (RCT) to determine the effectiveness and cost-effectiveness of Yoga for chronic Low Back Pain, which is funded by Arthritis Research Campaign (arc) and is being conducted by the University of York. 262 patients will be recruited from GP practices in 5 centres in England. Patients will be randomised to receive usual care or 12 weekly classes of yoga. A yoga programme will be devised that can be delivered by yoga teachers of the two main national yoga organisations in the UK (British Wheel of Yoga and Iyengar Yoga Association (UK)).

18.  Treatment Preferences for CAM in Children with Chronic Pain 
CAM therapies have become increasingly popular in pediatric populations. Yet, little is known about children's preferences for CAM. This study examined treatment preferences in chronic pediatric pain patients offered a choice of CAM therapies for their pain. Participants were 129 children (94 girls) (mean age = 14.5 years ± 2.4; range = 8–18 years) presenting at a multidisciplinary, tertiary clinic specializing in pediatric chronic pain. Bivariate and multivariate analyses were used to examine the relationships between CAM treatment preferences and patient's sociodemographic and clinical characteristics, as well as their self-reported level of functioning. Over 60% of patients elected to try at least one CAM approach for pain. The most popular CAM therapies were biofeedback, yoga and hypnosis; the least popular were art therapy and energy healing, with craniosacral, acupuncture and massage being intermediate. Patients with a diagnosis of fibromyalgia (80%) were the most likely to try CAM versus those with other pain diagnoses. In multivariate analyses, pain duration emerged as a significant predictor of CAM preferences. For mind-based approaches (i.e. hypnosis, biofeedback and art therapy), pain duration and limitations in family activities were both significant predictors. When given a choice of CAM therapies, this sample of children with chronic pain, irrespective of pain diagnosis, preferred non-invasive approaches that enhanced relaxation and increased somatic control. Longer duration of pain and greater impairment in functioning, particularly during family activities increased the likelihood that such patients agreed to engage in CAM treatments, especially those that were categorized as mind-based modalities.

19.  Yoga for Children and Young People’s Mental Health and Well-Being: Research Review and Reflections on the Mental Health Potentials of Yoga 
This article discusses yoga as a potential tool for children to deal with stress and regulate themselves. Yoga provides training of mind and body to bring emotional balance. We argue that children and young people need such tools to listen inward to their bodies, feelings, and ideas. Yoga may assist them in developing in sound ways, to strengthen themselves, and be contributing social beings. First, we address how children and young people in today’s world face numerous expectations and constant stimulation through the Internet and other media and communication technologies. One reason why children experience stress and mental health challenges is that globalization exposes the youth all over the world to various new demands, standards, and options. There is also increased pressure to succeed in school, partly due to increased competition but also a diverse range of options available for young people in contemporary times than in the past. Our argument also partially rests on the fact that modern society offers plenty of distractions and unwelcome attractions, especially linked to new media technologies. The dominant presence of multimedia devices and the time spent on them by children are clear indicators of the shift in lifestyles and priorities of our new generation. While these media technologies are valuable resources in children and young people’s lives for communication, learning, and entertainment, they also result in constant competition for youngster’s attention. A main concept in our article is that yoga may help children and young people cope with stress and thus, contribute positively to balance in life, well-being, and mental health. We present research literature suggesting that yoga improves children’s physical and mental well-being. Similarly, yoga in schools helps students improve resilience, mood, and self-regulation skills pertaining to emotions and stress.

20.  Iyengar Yoga and the Use of Props for Pediatric Chronic Pain: A Case Study 
Iyengar yoga uses postures and props to support the body so that practitioners can engage in poses that would otherwise be more difficult. This type of yoga may be useful in treating children and adolescents who have chronic pain and disability. In this case study, the authors discuss a 14-y-old girl who had two surgeries for gastro-esophageal reflux disease (GERD) and who had continued chest and abdominal pain, as well as vomiting, difficulty eating, weight loss, and anxiety. Having significantly impaired functioning, she was unable to attend school, sleep, socialize, or eat, and she had become wheelchair-bound. Despite evaluations and treatments by specialists over an extended period of time, her symptoms had not improved. This case history describes how the authors used a 4-mo treatment of Iyengar yoga to help the adolescent resume activities and re-engage with her environment. The authors intend this report to stimulate scientific study of this form of treatment for children and adolescents with chronic pain.

21.  Peer mentorship to promote effective pain management in adolescents: study protocol for a randomised controlled trial 
Trials  2011;12:132.
This protocol is for a study of a new program to improve outcomes in children suffering from chronic pain disorders, such as fibromyalgia, recurrent headache, or recurrent abdominal pain. Although teaching active pain self-management skills through cognitive-behavioral therapy (CBT) or a complementary program such as hypnotherapy or yoga has been shown to improve pain and functioning, children with low expectations of skill-building programs may lack motivation to comply with therapists' recommendations. This study will develop and test a new manualized peer-mentorship program which will provide modeling and reinforcement by peers to other adolescents with chronic pain (the mentored participants). The mentorship program will encourage mentored participants to engage in therapies that promote the learning of pain self-management skills and to support the mentored participants' practice of these skills. The study will examine the feasibility of this intervention for both mentors and mentored participants, and will assess the preliminary effectiveness of this program on mentored participants' pain and functional disability.
This protocol will recruit adolescents ages 12-17 with chronic pain and randomly assign them to either peer mentorship or a treatment-as-usual control group. Mentored participants will be matched with peer mentors of similar age (ages 14-18) who have actively participated in various treatment modalities through the UCLA Pediatric Pain Program and have learned to function successfully with a chronic pain disorder. The mentors will present information to mentored participants in a supervised and monitored telephone interaction for 2 months to encourage participation in skill-building programs. The control group will receive usual care but without the mentorship intervention. Mentored and control subjects' pain and functioning will be assessed at 2 months (end of intervention for mentored participants) and at 4 month follow-up to see if improvements persist. Measures of treatment adherence, pain, disability, and anxiety and depression will be assessed throughout study participation. Qualitative interviews for mentors, mentored participants, and control subjects will also be administered.

22.  Characteristics of Yoga Users: Results of a National Survey 
Journal of General Internal Medicine  2008;23(10):1653-1658.
There are limited data on the characteristics of yoga users in the U.S.
To characterize yoga users, medical reasons for use, perceptions of helpfulness, and disclosure of use to medical professionals.
Utilizing cross-sectional survey data from the 2002 National Health Interview Survey (NHIS) Alternative Medicine Supplement (n = 31044), we examined correlates of yoga use for health. The estimated prevalence from 2002 NHIS of yoga for health was 5.1% corresponding to over 10 million adults.
In 2002, yoga users were predominately Caucasian (85%) and female (76%) with a mean age of 39.5 years. Compared to non-yoga users, yoga users were more likely female (OR 3.76, 95% CI 3.11–4.33); less likely black than white (OR 0.65, 95% CI 0.53–0.80); tended to be younger; and more likely college educated (OR 2.70, 95% CI 2.37–3.08). Musculoskeletal conditions (OR 1.61, 95% CI 1.42–1.83), mental health conditions (OR 1.43, 95% CI 1.22–1.67), severe sprains in the last 12 months (OR 1.49, 95% CI 1.22–1.81), and asthma (OR 1.27, 95% CI 1.05–1.54) were independently associated with higher yoga use, while hypertension (OR 0.78, 95% CI 0.64–0.95) and chronic obstructive lung disease (OR 0.69, 95% CI 0.48–1.00) were associated with lower use. Yoga was most commonly used to treat musculoskeletal or mental health conditions, and most users reported yoga to be helpful for these conditions. A majority of yoga users (61%) felt yoga was important in maintaining health, though only 25% disclosed yoga practice to their medical professional.
We found that yoga users are more likely to be white, female, young and college educated. Yoga users report benefit for musculoskeletal conditions and mental health, indicating that further research on the efficacy of yoga for the treatment and/or prevention of these conditions is warranted.

23.  Yoga in adult cancer: an exploratory, qualitative analysis of the patient experience 
Some patients receiving treatment in conventional health care systems access therapeutic yoga outside their mainstream care to improve cancer symptoms. Given the current knowledge gap around patient preferences and documented experiences of yoga in adult cancer, this study aimed to describe patient-reported benefits, barriers and characteristics of programming for yoga practice during conventional treatment.
In depth semi-structured interviews (n = 10) were conducted in men and women recruited from cancer care clinics in Vancouver, Canada using a purposive sampling technique. The exploratory interviews were audio-recorded, transcribed and analyzed using Interpretive Description methodology and constant comparative analysis methods.
Four themes emerged from the data to address our research objectives: patient-perceived benefits of yoga, reasons and motivations for practising yoga, hurdles and barriers to practising yoga, and advice for effective yoga program delivery in adult cancer. Several patients reported yoga reduced stress and other symptoms associated with cancer treatment. Thematic analysis found the social dimension of group yoga was important, as well as yoga’s ability to encourage personal empowerment and awareness of physical body and self. Barriers to yoga adherence from the patient perspective included lack of time, scheduling conflicts and worries about financial burden.
This small, diverse sample of patients reported positive experiences and no adverse effects following yoga practice for management of cancer and its symptoms. Results of this qualitative study identified patient-reported preferences, barriers and characteristics of yoga intervention optimal during adult cancer treatment.

24.  Yoga reduces inflammatory signaling in fatigued breast cancer survivors: A randomized controlled trial 
Psychoneuroendocrinology  2014;43:20-29.
Yoga is a popular mind-body therapy that has demonstrated beneficial effects on psychological, behavioral, and functional outcomes. However, few studies have investigated effects on inflammatory processes. This study tested the hypothesis that an Iyengar yoga intervention specifically designed for fatigued breast cancer survivors would lead to decreases in inflammation-related gene expression and circulating markers of proinflammatory cytokine activity.
Breast cancer survivors with persistent cancer-related fatigue were randomized to a 12-week Iyengar yoga intervention (n = 16) or a 12-week health education control condition (n = 15). Blood samples were collected at baseline, post-intervention, and at a 3-month follow-up for genome-wide transcriptional profiling and bioinformatic analyses. Plasma inflammatory markers and salivary cortisol were also assessed.
In promoter-based bioinformatics analyses, the yoga group showed reduced activity of the pro-inflammatory transcription factor nuclear factor kappa B (NF-κB), increased activity of the anti-inflammatory glucocorticoid receptor, and reduced activity of cAMP response element-binding protein (CREB) family transcription factors relative to controls (all ps < .05). There was also a significant intervention effect on the soluble tumor necrosis factor receptor type II (sTNF-RII), a marker of TNF activity; plasma levels of sTNF-RII remained stable in the yoga group, whereas levels of this marker increased in the health education group (p = .028). A similar, non-significant trend was observed for the interleukin 1 receptor antagonist (p = .16). No significant changes in C reactive protein (CRP), interleukin 6 (IL-6), or diurnal cortisol measures were observed.
A 12-week restorative Iyengar yoga intervention reduced inflammation-related gene expression in breast cancer survivors with persistent fatigue. These findings suggest that a targeted yoga program may have beneficial effects on inflammatory activity in this patient population, with potential relevance for behavioral and physical health. identifier: NCT00727662.

25.  A Narrative Review of Yoga and Mindfulness as Complementary Therapies for Addiction 
This paper reviews the philosophical origins, current scientific evidence, and clinical promise of yoga and mindfulness as complementary therapies for addiction. Historically, there are eight elements of yoga that, together, comprise ethical principles & practices for living a meaningful, purposeful, moral and self-disciplined life. Traditional yoga practices, including postures and meditation, direct attention towards one’s health, while acknowledging the spiritual aspects of one’s nature. Mindfulness derives from ancient Buddhist philosophy, and mindfulness meditation practices, such as gentle Hatha yoga and mindful breathing, are increasingly integrated into secular health care settings. Current theoretical models suggest that the skills, insights, and self-awareness learned through yoga and mindfulness practice can target multiple psychological, neural, physiological, and behavioral processes implicated in addiction and relapse. A small but growing number of well-designed clinical trials and experimental laboratory studies on smoking, alcohol dependence, and illicit substance use support the clinical effectiveness and hypothesized mechanisms of action underlying mindfulness-based interventions for treating addiction. Because very few studies have been conducted on the specific role of yoga in treating or preventing addiction, we propose a conceptual model to inform future studies on outcomes and possible mechanisms. Additional research is also needed to better understand what types of yoga and mindfulness-based interventions work best for what types of addiction, what types of patients, and under what conditions. Overall, current findings increasingly support yoga and mindfulness as promising complementary therapies for treating and preventing addictive behaviors.
