Effect of Hatha Yoga on Anxiety: A Meta-Analysis

Practice and proficiency of Isha Yoga for better mental health outcomes: insights from a COVID-19 survey

Introduction

The COVID-19 pandemic has brought about unparalleled suffering on a global scale, affecting both physical and mental well-being. In such challenging times, it becomes crucial to identify interventions that can alleviate negative mental health outcomes, such as stress, while promoting positive mental health outcomes, like well-being. We report the effectiveness of a mind-body practise, Isha Yoga, in promoting well-being.

Methods

We conducted an online survey, during the COVID-19 pandemic, with Yoga practitioners (n = 1,352) from the Isha Yoga tradition in Karnataka, India. We evaluated stress and well-being attributes using conventional psychometric questionnaires. Subsequently, we requested the Isha Yoga practitioners to share another survey with their friends and family members, assessing similar outcomes. From the respondents of this shared survey (n = 221), we identified individuals who currently did not engage in any form of Yoga or meditation, constituting the non-Yoga control group (n = 110). To enhance the reliability and validity of our study and minimize the limitations commonly associated with online surveys, we adhered to the CHERRIES guidelines for reporting survey studies.

Results

Isha Yoga practitioners had significantly lower levels of stress (p < 0.001, gHedges = 0.94) and mental distress (p < 0.001, gHedges = 0.75) while reporting significantly higher levels of well-being (p < 0.001, gHedges = 0.78) and affective balance (p < 0.001, gHedges = 0.80) compared to the control group. Furthermore, expertise-related improvements were observed in these outcomes, and a dose-response relationship was found between regularity of Isha Yoga practice and outcome changes. A minimum 3-4 days of weekly practice showed significant differences with the control group. In addition, we investigated the effect of Isha Yoga on stress and well-being among the healthcare workers (HCWs) in our sample and observed better mental health outcomes.

Discussion

These findings collectively underscore the benefits of Mind and Body practices like Isha Yoga on various aspects of mental health and well-being, emphasizing its potential as an effective and holistic approach for promoting a healthy lifestyle among diverse populations, including healthcare workers, even in difficult circumstances such as the COVID-19 pandemic.

Yoga classes as an early intervention for college students reporting high levels of stress and anxiety: A pilot study

Background:Today's college students are experiencing unprecedented rates of stress, anxiety, and mental health issues. As a result, college counseling centers are often overwhelmed by the demand for mental health services. Methods: The current study evaluated the potential for Hatha yoga classes to be used as an alternative to conventional psychotherapy for college students reporting high levels of stress and anxiety. Results: After 6 weeks of twice-weekly, hour-long yoga classes, significant reductions in stress, anxiety, pathological worry, and rumination were reported by 7 undergraduate college students. Conclusions: Results of this pilot study suggest that Hatha yoga classes may serve as a widely accessible, cost-effective early intervention that can be offered as a first-line recommendation to students who are struggling with heightened levels of stress and anxiety.

Traditional, Complementary and Alternative Medicines in the Treatment of Ejaculatory Disorders: A Systematic Review

Background and Objectives: Ejaculatory dysfunction (EjD) is a common male sexual disorder that includes premature ejaculation, delayed ejaculation, retrograde ejaculation, and anejaculation. Although psychological and pharmacological treatments are available, traditional, complementary, and alternative medicine (TCAM) is reportedly used. However, the clinical evidence for TCAM in EjD remains unclear. Therefore, this study aims to systematically review human clinical trials investigating the use of TCAM to treat EjD. Materials and Methods: A systematic review of the literature following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted by searching Scopus and PubMed databases. Controlled clinical trials investigating a cohort of male patients diagnosed primarily with EjD and undergoing any TCAM intervention compared to any comparison group were included. Quality of the studies was assessed using the Cochrane Risk of Bias tool for randomized controlled trials. Results: Following article screening, 22 articles were included. Of these, 21 investigated TCAM in premature ejaculation, and only 1 investigated TCAM in retrograde ejaculation. Different TCAM categories included studies that investigated lifestyle, exercise and/or physical activities (n = 7); herbal medicine supplements (n = 5); topical herbal applications (n = 4); acupuncture or electroacupuncture (n = 3); vitamin, mineral and/or nutraceutical supplements (n = 1); hyaluronic acid penile injection (n = 1); and music therapy (n = 1). Only 31.8% (n = 7) of the included studies were found to have a low risk of bias. The available studies were widely heterogenous in the TCAM intervention investigated and comparison groups used. However, the included studies generally showed improved outcomes intra-group and when compared to placebo. Conclusions: Different TCAM interventions may have an important role particularly in the management of PE. However, more studies using standardized interventions are needed.

The role of non-ordinary states of consciousness occasioned by mind-body practices in mental health illness

BACKGROUND

Research with hallucinogens suggests that non-ordinary states of consciousness (NOSCs), particularly mystical-type experiences, predict improvements in various affective disorders and substance use disorders (SUDs). Little is known, however, about the therapeutic potential of NOSCs induced by mind-body practices such as meditation, yoga and breathwork.

METHODS

We conducted a literature review in online databases (PubMed, Scopus, Google Scholar) and preprint databases (SSRN, bioRxiv) to identify studies of NOSCs induced by mind-body practices and their effects in affective disorders and SUDs.

RESULTS

A wide variety of mind-body practices involving physical movement (i.e., shamanic drumming, yoga) and hyper-focused immersive mental experiences (i.e., meditation, breathwork) have been reported in the literature. Preliminary evidence, mostly from qualitative studies and open label studies, suggest that mind-body practices produce NOSCs. Such experiences have been associated with short-term reduced levels of anxiety and depression, increased motivation to quit addictive behaviors, and enhanced self-awareness and spiritual well-being.

LIMITATIONS

Findings are limited by the scarcity of literature in this field. Further rigorous and methodologically sound empirical research is needed, including comparative studies of NOSCs occasioned by different methods.

CONCLUSIONS

Mind-body practices may represent a promising approach for treating mental health disorders. The NOSCs induced by such practices may lead to beneficial shifts in perceptions, values, beliefs, and behaviors. Given the challenges with hallucinogen-based therapies, mind-body practices may represent a more accessible and acceptable way of eliciting potentially helpful NOSCs in clinical practice.

Yoga as an Integrated Holistic Approach to Oral Health: A Review

Objectives

The association between various systemic diseases and periodontitis has been explored extensively. A sedentary lifestyle plays a significant role in systemic and periodontal disease progression. Therefore, lifestyle modification has been considered a component of therapeutic aspects for periodontal disease and systemic disease. This review focuses on how yoga may reduce chronic gingival inflammation by improving the body's defense, which can act more efficiently on periodontal bacteria and help maintain healthy gingiva.

Materials and Methods

A literature search was performed in PubMed/MEDLINE CINAHL, Web of Science, and Google Scholar for all the published articles related to yoga and its systemic benefits and potential role in reducing periodontal breakdown, and the findings were summarized.

Results

The practice of yoga therapy has been proven to show several benefits, such as reduced stress levels, anxiety and depression, increased antioxidant levels, reduced insulin resistance, and improved respiratory function. It also helps to improve the immune system.

Conclusion

Yoga can be used as a potential treatment modality adjunct to conventional periodontal therapy as it has been shown to have a potential benefit in controlling systemic risk factors.

A systematic review of compassion-based interventions for individuals struggling with body weight shame

OBJECTIVE

This systematic review investigated compassion-based interventions and the extent to which they can assist with addressing body weight shame.

DESIGN

The systematic review was pre-registered and conducted according to PRISMA guidelines. Seven electronic databases (PsycNET, Pubmed, Web of science, CINAHL, Scopus, ProQuest, Social Science Database) were searched. The methodological quality of studies was also assessed.

MAIN OUTCOME MEASURES

Main outcomes were body weight shame, and compassion. Secondary outcomes assessed were mental health, eating attitudes and behaviours, physical exercise and Body Mass Index and weight.

RESULTS

25 studies (23 papers) met inclusion criteria and results indicated promise for compassion-based interventions for body weight shame, compassion, and health related behaviour. Mixed results were found for BMI and weight. The studies varied considerably in terms of populations targeted, the duration of interventions, and intervention delivery.Conclusion: Overall, compassion-based interventions were found to reduce body weight shame and improve levels of compassion. However, the impact of compassion-based interventions on BMI and weight is less promising. Recommendations for future research are provided.

Impact of preference for yoga or cognitive behavioral therapy in patients with generalized anxiety disorder on treatment outcomes and engagement

There is some, but inconsistent, evidence to suggest that matching patient treatment preference enhances treatment engagement and outcome. The current study examined differential preferences and factors associated with treatment preference for 12-week group cognitive behavioral therapy (CBT), yoga, or stress education in 226 adults with generalized anxiety disorder (GAD; 70% female, Mean age = 33 ± 13.5). In a subsample of 165 patients who reported an intervention preference and were randomized to yoga or CBT, we further examined whether match to preferred intervention improved the primary treatment outcome (responder status on Clinical Global Impressions Scale) and engagement (dropout, homework compliance). Preferences for CBT (44%) and yoga (40%) were similar among patients. Women tended to prefer yoga (OR = 2.75, p = .01) and CBT preference was associated with higher baseline perceived stress (OR = 0.92, p = .04) and self-consciousness meta-cognitions (OR = 0.90, p = .02). Among those not matched to their preference, treatment response was higher for those receiving CBT than yoga (OR = 11.73, p = .013); there were no group differences for those matched to their treatment preference. In yoga, those who received their preference were more likely to drop than those who did not (OR = 3.02, 95% CI = [1.20, 7.58], p = .037). This was not the case for CBT (OR = 0.37, 95% CI = [0.13, 1.03], p = .076). Preference match did not predict homework compliance. Overall, results suggest that treatment preference may be important to consider to optimize outcome and engagement; however, it may vary by treatment modality. Future research incorporating preference, especially with yoga for anxiety, is aligned with personalized medicine.

Effects of combined aerobic-strength training and yoga on quality of life and related parameters in women with pituitary adenoma after surgery: a randomized crossover study

OBJECTIVE

The pituitary gland is responsible for hormonal balance in the body, and disruption of hormonal balance in patients with pituitary adenoma (PA) indirectly affects the quality of life. This study aimed to examine the effects of yoga and combined aerobic and strength training (A+ST) on quality of life and related parameters such as sleep, fatigue, emotional state, sexual function, and cognitive status in women with PA.

DESIGN

Ten women with PA were included in this randomized crossover study. Group 1 (n = 5, mean age: 52 ± 13.5 years) received A+ST for the first 6 weeks, a 2-week washout period, and yoga for the second 6 weeks. Group 2 (n = 5, mean age: 41.8 ± 14 years) received the yoga program first, followed by the A+ST program.

METHODS

Participants were assessed using the following tools before and after each exercise intervention: Functional Assessment of Cancer Therapy-Brain (FACT-Br) (quality of life), Pittsburg Sleep Quality Index, Fatigue Severity Scale (FSS), Female Sexual Function Index (FSFI), Hospital Anxiety and Depression Scale (HADS), and Montreal Cognitive Assessment Scale (MOCA).

RESULTS

FACT-Br scores were higher after the yoga program, HADS anxiety score was lower after the A+ST program, and MOCA scores increased after both exercise programs (P < 0.05). FSS score decreased after both exercise programs, but not significantly. In addition, nonsignificant decreases in HADS anxiety and depression scores and increased FSFI scores were observed after the yoga program.

CONCLUSION

A+ST and yoga have positive effects on the quality of life in PA. We recommend yoga and A+ST as a supportive therapy for this population that may face comorbidities after surgical and medical treatment. Our results indicate these patients may benefit from physiotherapist-guided exercise programs.

Role of Yoga practices on cognitive functions

Yoga is the science of conditioning one's mind and body via the practise of shatkarma, asana, pranayama, mudra, and meditation. The aim of this review of literature is to give theoretical rationale for identifying (a) the specific attributes of yoga poses that have been used in yoga protocols of various studies but have not been explicitly explored, & (b) the minimum time necessary to keep a posture to bring about a corresponding change in performance among the aforementioned cognitive functions (s) In humans, The most prevalent and under-treated problems are cognitive decline & psychological health problems. Different studies have been carried out to determine the influence of Yoga on human cognitive and psychological health indices. However, no comprehensive examination of the effects of yoga-based therapy on human cognitive and mental health has been undertaken to far. Yoga is an ancient science that places a premium on disease prevention and treatment, as well as the percentage of health. Yoga is recognized to delay the effects of aging and has been found to be effective in the therapy of aging-related disorders. Yoga is a centuries-old discipline that is said to improve both physical and emotional well-being.

Comparing Aerobic Exercise with Yoga in Anxiety Reduction: An Integrative Review

Anxiety is a common mental health disorder that affects many Americans yet often goes unrecognized or undertreated. The purpose of this article is to review the current literature to assist in determining which alternative and complimentary therapy, aerobic exercise or yoga, is most beneficial in reducing anxiety symptoms. The literature search process resulted in a total of 14 articles included in the review. Results indicate that yoga is more effective in decreasing anxiety symptoms than aerobic exercise. Health care providers can use this information to help recommend an alternative form of therapy for patients.

Role of Yoga as an Adjunct in the Management of Migraine Headache-Current Status and Future Indications

Migraine headache is a painful, disabling condition afflicting 7% of the population. The long-term effort of coping with a chronic headache disorder predisposes the individual to other psychiatric illnesses, ischemic cerebrovascular disease as well as medicine overuse headache. The use of nonpharmacological methods to reduce the stress and pain associated with headache can improve the overall quality of life and reduce the burden of the disease. To examine the utility of yoga as an adjunct to pharmacological treatment of migraine headache. The review article is based on the secondary literature collected through the Google Scholar database between the years 2010 and 2020. Several themes were identified regarding the burden of migraine/headache and the need for the integration of yoga into the existing healthcare system. Despite the limitations and the need for greater scientific rigor, there have been consistent reports of the beneficial effects of yoga in the reduction of stress, anxiety, depression, and an enhanced quality of life, as well as better pain management in chronic diseases. Studies on the role of yoga in the treatment of migraine have been few in number. They have consistently shown that yoga can be a valuable adjunct to the existing pharmacological interventions in the management of migraine headache. In recent years, the Indian government has made enormous strides in establishing yoga outreach programs throughout the country. The need of the hour is to integrate evidence-based yoga with the wellness centers and noncommunicable diseases treatment plan. It can help to reduce the burden on the existing health care resources.

Therapeutic role of yoga in neuropsychological disorders

Yoga is considered a widely-used approach for health conservation and can be adopted as a treatment modality for a plethora of medical conditions, including neurological and psychological disorders. Hence, we reviewed relevant articles entailing various neurological and psychological disorders and gathered data on how yoga exerts positive impacts on patients with a diverse range of disorders, including its modulatory effects on brain bioelectrical activities, neurotransmitters, and synaptic plasticity. The role of yoga practice as an element of the treatment of several neuropsychological diseases was evaluated based on these findings.

The effect of yoga on pain level in primary dysmenorrhea

This study was conducted to evaluate the effect of yoga on pain levels in female students with primary dysmenorrhea. This study is a randomized experimental study with control group and pretest post-test practice. This study included 60 volunteer female students (30 experimental and 30 control groups). The patients in the experimental group took part in the yoga program a total of 12 sessions, once per week for 12 weeks. "Personal Information Form", "Visual Analog Skala (VAS)" and "Dysmenorrhea Monitoring Form (DMF)" were used in data collection process. To measure dysmenorrhea pain, the students were requested to mark a number between 1 and 10 on the VAS scale according to the severity of their pain on the menstruation starting date. The yoga applications were used for three menstrual cycles. The mean age of the students in the experimental group was 20.30 ± 0.46, while the mean age of the students in the control group was 20.46 ± 0.50. The difference between the pain levels of the students in the experimental group in the first, second, third and fourth measurements was found to be statistically significant (p < 0.001). It was determined that the difference between the pain levels of the students in the control group in the first, second, third and fourth measurements was not statistically significant (p > 0.05). Yoga can be used as an effective intervention in reducing menstrual pain in women with primary dysmenorrhea.

Heart rate and heart rate variability as outcomes and longitudinal moderators of treatment for pain across follow-up in Veterans with Gulf War illness

AIMS

Accumulating evidence suggests Gulf War illness (GWI) is characterised by autonomic nervous system dysfunction (higher heart rate [HR], lower heart rate variability [HRV]). Yoga - an ancient mind-body practice combining mindfulness, breathwork, and physical postures - is proposed to improve autonomic dysfunction yet this remains untested in GWI. We aimed to determine (i) whether HR and HRV improve among Veterans with GWI receiving either yoga or cognitive behavioural therapy (CBT) for pain; and (ii) whether baseline autonomic functioning predicts treatment-related pain outcomes across follow-up.

MAIN METHODS

We present secondary analyses of 24-hour ambulatory cardiac data (mean HR, square root of the mean squared differences between successive R-R intervals [RMSSD], high frequency power [HF-HFV], and low-to-high frequency ratio [LF/HF] extracted from a 5-min window during the first hour of sleep) from our randomised controlled trial of yoga versus CBT for pain among Veterans with GWI (ClinicalTrials.govNCT02378025; N = 75).

KEY FINDINGS

Veterans who received CBT tended towards higher mean HR at end-of-treatment. Better autonomic function (lower mean HR, higher RMSSD/HF-HRV) at baseline predicted greater reductions in pain across follow-up, regardless of treatment group. Better baseline autonomic function (mid-range-to-high RMSSD/HF-HRV) also predicted greater pain reductions with yoga, while worse baseline autonomic function (higher mean HR, lower RMSSD/HF-HRV) predicted greater pain reductions with CBT.

SIGNIFICANCE

To our knowledge, this is the first study to suggest that among Veterans with GWI, HR may increase with CBT yet remain stable with yoga. Furthermore, HR and HRV moderated pain outcome across follow-up for yoga and CBT.

A pilot study of the acceptability, feasibility and safety of yoga for chronic pain in sickle cell disease

OBJECTIVES

To determine the acceptability, feasibility and safety of yoga for chronic pain in sickle cell disease.

DESIGN AND SETTING

In Part A of this two-part study, adolescents with SCD and chronic pain (Group 1) and their parent (Group 2) completed a survey designed to capture pain characteristics, attitudes and practices related to yoga, and potential acceptability of a yoga program. In Part B, the study assessed the feasibility and safety of an instructor-led group yoga program. The study was registered on clinicaltrials.gov (NCT03694548).

INTERVENTION

Eight instructor-led group yoga sessions.

MAIN OUTCOME MEASURES

Feasibility and safety outcomes were chosen a priori, as follows: 1) Proportion of adolescent patients with SCD and chronic pain approached that consent to participate in Part A, 2) Proportion of adolescent participants enrolled in Part A that consent to participate in Part B, 3) Proportion of participants enrolled in Part B that attend at least 6 of 8 yoga sessions, 4) Proportion of participants enrolled in Part B with an ED visit or a hospitalization for pain within 24 h of completion of each yoga session, 5) Proportion of participants in Part B who complete all study assessments before, and at the end of the yoga program, 6) Adherence to submission of pain diary.

RESULTS

The median age of 15 patient participants in Part A was 16 (IQR 14-17), and 14 parents was 43.5 (IQR 42-51). Most participants were female. Most participant responses indicated a positive opinion of yoga. Nine adolescents (60 %) from Part A participated in Part B of the study. The median age of 9 participants in Part B was 17 (IQR 15-18), and 5 of the 9 participants were female (53.3 %). Only one participant was able to attend 3 of the 8 yoga sessions offered, and did not experience any ED visits or hospitalizations following the yoga sessions. None of the other feasibility endpoints were met in this study.

CONCLUSIONS

Patients with SCD and chronic pain overall have a positive opinion of yoga, but there are challenges with recruitment and retention of participants in a clinical trial of yoga, and barriers to feasibility of an in-person group yoga intervention.

COVID-19: Knowledge, anxiety, academic concerns and preventative behaviours among Australian and Indian undergraduate nursing students: A cross-sectional study

AIMS AND OBJECTIVES

To compare knowledge, anxiety, academic concerns and preventative behaviours between undergraduate nursing students in Australia and India during the COVID-19 pandemic.

BACKGROUND

Based on the World Health Organization's direction for containment of the novel coronavirus (COVID-19), countries implemented varying levels of restrictions including closure of university campuses and providing on line undergraduate education.

METHODS

Students in NSW, Australia and Kerala, India completed an online survey assessing their (a) knowledge and source of information about COVID-19; (b) anxiety; and coping strategies; (c) academic concerns; and (d) preventative behaviours. Descriptive and inferential statistics were used to summarise the data.

RESULTS

Data from 99 Australian and 113 Indian undergraduate nurses were analysed. Greater number of Indian students indicated having sufficient knowledge of COVID-19 (OR 0.22; 95% CI 0.08, 0.63), getting information about COVID-19 from social media (OR 0.03; 95% CI 0.01, 0.07) and being concerned about 'attending clinical placement' (MD-1.08; 95% CI -1.94, -0.23). Australian students reported significantly higher levels of anxiety (MD 1.99 95% CI 1.21, 2.78), difficulty sleeping (OR 18.00; 95% CI 6.76, 47.96), concentrating (OR 33.22; 95% CI 13.85, 79.67) and eating (OR 14.05; 95% CI 3.19, 61.84). Greater number of Australian students indicated that they would go to the University if they needed to meet with other students (OR 9.21; 95% CI 3.08, 27.55), had to access the library (OR 7.20; 95% CI 3.26, 15.90) or had a group assignment (OR 2.93; 95% CI 1.26, 6.77).

CONCLUSIONS

Wide variations were present in knowledge, anxiety, academic concerns and preventative behaviours among undergraduate nursing students in two countries.

RELEVANCE TO CLINICAL PRACTICE

Undergraduate students may benefit from additional support from the University and staff in the clinical setting with online learning and resources in order to adjust to the 'new normal' and enable them to achieve academic success.

Can Yoga or Physical Therapy for Chronic Low Back Pain Improve Depression and Anxiety Among Adults From a Racially Diverse, Low-Income Community? A Secondary Analysis of a Randomized Controlled Trial

OBJECTIVE

To determine and compare the effect of yoga, physical therapy (PT), and education on depressive and anxious symptoms in patients with chronic low back pain (CLBP).

DESIGN

Secondary analysis of a randomized controlled trial.

SETTING

Academic safety net hospital and 7 community health centers.

PARTICIPANTS

A total of 320 adults with CLBP.

INTERVENTION

Yoga classes, PT sessions, or an educational book.

OUTCOME MEASURE

Depression and anxiety were measured using the Patient Health Questionnaire and Generalized Anxiety Disorder 7-item Scale, respectively, at baseline, 12, and 52 weeks. We identified baseline and midtreatment (6-wk) factors associated with clinically meaningful improvements in depressive (≥3 points) or anxious (≥2 points) symptoms at 12 weeks.

RESULTS

Participants (female=64%; mean age, 46.0±10.7 years) were predominantly non-White (82%), low-income (<$30,000/year, 59%), and had not received a college degree (71%). Most participants had mild or worse depressive (60%) and anxious (50%) symptoms. At 12 weeks, yoga and PT participants experienced modest within-group improvements in depressive symptoms (mean difference [MD]=-1.23 [95% CI, -2.18 to -0.28]; MD=-1.01 [95% CI, -2.05 to -0.03], respectively). Compared with the education group, 12-week differences were not statistically significant, although trends favored yoga (MD=-0.71 [95% CI, -2.22 to 0.81]) and PT (MD= -0.32 [95% CI, -1.82 to 1.18]). At 12 weeks, improvements in anxious symptoms were only found in participants who had mild or moderate anxiety at baseline. Independent of treatment arm, participants who had 30% or greater improvement in pain or function midtreatment were more likely to have a clinically meaningful improvement in depressive symptoms (odds ratio [OR], 1.82 [95% CI, 1.03-3.22]; OR, 1.79 [95% CI, 1.06-3.04], respectively).

CONCLUSIONS

In our secondary analysis we found that depression and anxiety, common in this sample of underserved adults with CLBP, may improve modestly with PT and yoga. However, effects were not superior to education. Improvements in pain and function are associated with a decrease in depressive symptoms. More research is needed to optimize the integration of physical and psychological well-being in PT and yoga.

Efficacy of Yoga vs Cognitive Behavioral Therapy vs Stress Education for the Treatment of Generalized Anxiety Disorder: A Randomized Clinical Trial

IMPORTANCE

Generalized anxiety disorder (GAD) is common, impairing, and undertreated. Although many patients with GAD seek complementary and alternative interventions, including yoga, data supporting yoga's efficacy or how it compares to first-line treatments are lacking.

OBJECTIVES

To assess whether yoga (Kundalini yoga) and cognitive behavioral therapy (CBT) for GAD are each more effective than a control condition (stress education) and whether yoga is noninferior to CBT for the treatment of GAD.

DESIGN, SETTING, AND PARTICIPANTS

For this randomized, 3-arm, controlled, single-blind (masked independent raters) clinical trial, participants were recruited from 2 specialty academic centers starting December 1, 2013, with assessment ending October 25, 2019. Primary analyses, completed by February 12, 2020, included superiority testing of Kundalini yoga and CBT vs stress education and noninferiority testing of Kundalini yoga vs CBT.

INTERVENTIONS

Participants were randomized to Kundalini yoga (n = 93), CBT for GAD (n = 90), or stress education (n = 43), which were each delivered to groups of 4 to 6 participants by 2 instructors during twelve 120-minute sessions with 20 minutes of daily homework.

MAIN OUTCOMES AND MEASURES

The primary intention-to-treat outcome was acute GAD response (Clinical Global Impression-Improvement Scale score of much or very much improved) after 12 weeks as assessed by trained independent raters.

RESULTS

Of 538 participants who provided consent and were evaluated, 226 (mean [SD] age, 33.4 [13.5] years; 158 [69.9%] female) with a primary diagnosis of GAD were included in the trial. A total of 155 participants (68.6%) completed the posttreatment assessment. Completion rates did not differ (Kundalini yoga, 60 [64.5%]; CBT, 67 [74.4%]; and stress education, 28 [65.1%]: χ2 = 2.39, df = 2, P = .30). Response rates were higher in the Kundalini yoga group (54.2%) than in the stress education group (33.%) (odds ratio [OR], 2.46 [95% CI, 1.12-5.42]; P = .03; number needed to treat, 4.59 [95% CI, 2.52-46.19]) and in the CBT group (70.8%) compared with the stress education group (33.0%) (OR, 5.00 [95% CI, 2.12-11.82]; P < .001; number needed to treat, 2.62 [95% CI, 1.91-5.68]). However, the noninferiority test did not find Kundalini yoga to be as effective as CBT (difference, 16.6%; P = .42 for noninferiority).

CONCLUSIONS AND RELEVANCE

In this trial, Kundalini yoga was efficacious for GAD, but the results support CBT remaining first-line treatment.

Integrating yoga with psychological group-treatment for mixed depression and anxiety in primary healthcare: An explorative pilot study

BACKGROUND AND PURPOSE

Yoga has shown promise as a treatment for depression and anxiety. The present pilot study investigated the feasibility of an eight-week grouptreatment integrating emotion-focused psychoeducation, compassion-focused therapy, and Virya yoga for depression and anxiety in primary healthcare.

MATERIALS AND METHODS

Patients seeking treatment for depression and anxiety in a primary healthcare centre completed either an integrative group-treatment (N = 14) or treatment as usual (TAU, N = 17). Outcome measures were analysed pre- and posttreatment. Correlations in the intervention group were investigated between treatment outcomes and amount of yoga practice between sessions.

RESULTS

Large within-group effect sizes on all outcome measures were found at posttreatment. Symptom reduction did not differ between groups (p = 0.155). Improvement in alexithymia correlated significantly (p < 0.05) with amount of yoga practice between sessions.

CONCLUSION

Integrating yoga with a psychological group-treatment is a somewhat feasible approach to treatment for depression and anxiety in primary healthcare.

Integrating complementary and alternative therapies into professional psychological practice: An exploration of practitioners' perceptions of benefits and barriers

BACKGROUND AND PURPOSE

Although Complementary and Alternative Therapies (CATs) are currently incorporated into psychotherapy, scepticism remains among professional and practicing psychologists about integration of CATs into professional practice. This research explored perceived benefits and barriers to integrating CATs into psychology practice with individual clients.

MATERIALS AND METHODS

We used a qualitative framework informed by Transpersonal Psychology to explore benefits and barriers to integrative psychology practice. We conducted semi-structured interviews with six practitioners trained or training in psychology and CATs and analysed verbatim transcripts using thematic analysis.

RESULTS

Participants reported personal, career-based, and epistemological benefits and barriers to integrative psychology practice. Benefits were improved therapeutic relationships, specialisation options, and a time reflective psychology. Barriers included stigma and bias, regulations, and dominance of the scientist-practitioner model. Superordinate themes were holism, connectedness, and governance.

CONCLUSION

Results activate conversation about the importance of a transpersonally oriented integrative psychological practice for the 21st century.

A Comparison of the Acute Effects of Different Forms of Yoga on Physiological and Psychological Stress: A Pilot Study

Yoga is a frequently recommended stress management strategy; however, the acute stress response to varying types of yoga are not fully clear. Thus, the purpose of this study was to compare the acute effects of meditative and power yoga on indices of physiological and psychological stress. In a crossover counterbalanced design, physically active females (n = 13; age = 20.8 yrs ± 0.8, height = 164.5 cm ± 6.1, body mass = 65.0 kg ± 13.8) who did not regularly participate in yoga or mindful training enrolled in this study. Participants completed two visits each, with a standardized instructional-video 30-min yoga session with either A) meditative (Hatha style) yoga or B) power (Vinyasa style) yoga. Prior to and immediately after each yoga bout, psychological stress was assessed using the State–Trait Anxiety Inventory (STAI) questionnaire, and salivary cortisol samples were obtained to measure indices of physiological stress. State anxiety scores were significantly lower following meditative yoga (p = 0.047) but were not different following power yoga (p = 0.625). Salivary cortisol levels were significantly lower following meditative yoga (p = 0.020) but not following power yoga (p = 0.242). Results indicate that acute engagement in meditative yoga decreases markers of psychological and physiological stress, while power yoga does not impart a significant stress-relieving benefit. Findings indicate that differing types of yoga may have various stress-relieving capabilities and should be considered by individuals seeking anxiolytic benefits.

There is a non-evidence-based app for that: A systematic review and mixed methods analysis of depression- and anxiety-related apps that incorporate unrecognized techniques

BACKGROUND

Recent studies have utilized available online data to examine the impact of depression- and anxiety-related apps that incorporate evidence-based techniques; however, the impact of apps incorporating non-evidence-based techniques is unknown. Understanding this impact is important in order to assess the potential benefits or harm from their use.

METHODS

We systematically reviewed apps incorporating relevant techniques aimed at depression- and anxiety-related conditions, found through Google Play search. We conducted quantitative and qualitative analyses of user reviews, and analyzed app usage utilizing an independent user panel.

RESULTS

Compared to apps incorporating evidence-based techniques (n = 14), user ratings of apps classified as non-evidence-based (n = 27) were lower (4.0 versus 4.5, p=.001, η²=0.24) and a smaller percentage of users found these apps to be beneficial for mental health (76.2% versus 100%, p=.003, η²=0.23). Users found apps incorporating non-evidence-based techniques to be mostly helpful in providing in-the-moment relief; however, some users described these apps as containing content that could be harmful for a person in such a mental state.

LIMITATIONS

The data do not enable the differentiation of user experiences based on user groups (e.g. according to the severity of symptoms), which should be examined in future studies.

CONCLUSIONS

This study indicates that depression and anxiety apps incorporating non-evidence-based techniques are viewed less favorably and have more potential to cause harm. However, many users found them helpful mostly in providing in-the-moment relief. Examining user experiences with these apps is an important way to learn about unmet user needs and potential benefits or harm.

Effect of yoga-based physical activity on perceived stress, anxiety, and quality of life in young adults

PURPOSE

This study, conducted at a public university in Turkey, sought to determine the effects of yoga-based physical activity on perceived stress, anxiety, and quality of life in young adults.

DESIGN AND METHODS

This study was planned as a semiexperimental nonrandomized study with a control group.

FINDINGS

Yoga-based physical activity decreased the perceived stress and state anxiety levels, but had no effect on trait anxiety levels and quality of life.

PRACTICAL IMPLICATIONS

It is recommended that yoga-based treatment can be included in nursing interventions for reducing stress and anxiety levels in young adults.

An Evaluation of Yoga and Meditation to Improve Attention, Hyperactivity, and Stress in High-School Students

Objective: Problems with attention and stress are common in children and predict academic difficulties and other behavioral and emotional problems. Mind-body interventions such as yoga and meditation improve attention and reduce stress. In this study, we examined the impact of Hatha yoga on attention and stress in ninth graders. Design: A total of 174 ninth graders from a Texas high school were enrolled in the study. Teachers assigned students to a yoga group (YG) or control group (CG) based on their class schedule. The YG participated in 25-min Hatha yoga classes twice weekly over 12 weeks (n = 123). The CG included 51 students. Student self-reports on measures of inattention and hyperactivity (the strengths and weaknesses of ADHD [attention-deficit/hyperactivity disorder] symptoms and normal behavior rating scale for ADHD) and stress (perceived stress scale) were obtained at baseline and at 12 weeks. Results: There were no significant differences in baseline levels of inattention (p = 0.86), hyperactivity (p = 0.25), and perceived stress (p = 0.28) between the YG and CG. Regarding inattention scores, there was a significant interaction of group and time (b = -1.09, standard error [SE] = 0.30, p < 0.001). Pairwise t-tests showed a significant reduction in inattention for the YG (d = 0.27) but a significant increase in inattention for the CG. Regarding hyperactivity, there was no significant interaction of group and time (b = -0.43, SE = 0.26, p = 0.1). Pairwise t-tests demonstrated a significant reduction in hyperactivity for the YG (d = 0.22), but not the CG. The interaction of group and time was not significant in predicting the slope of change in perceived distress (b = -0.93, SE = 1.19, p = 0.43). Pairwise t-tests did not show a significant reduction in perceived distress for either group. Conclusion: These findings suggest that Hatha yoga may improve attention and hyperactivity in high school students.

Brain and Physiological Markers of Autonomic Function Are Associated With Treatment-Related Improvements in Self-Reported Autonomic Dysfunction in Veterans With Gulf War Illness: An Exploratory Pilot Study

BACKGROUND

Gulf War Illness (GWI) is a poorly understood condition characterized by a constellation of mood, cognitive, and physical symptoms. A growing body of evidence demonstrates autonomic nervous system (ANS) dysfunction. Few published treatment studies exist for GWI.

METHOD

We recently completed a randomized controlled trial comparing a 10-week group yoga intervention to 10-week group cognitive behavioral therapy (CBT) for veterans with GWI. Here, we present exploratory data on ANS biomarkers of treatment response from a small pilot exploratory neurophysiological add-on study (n = 13) within that larger study.

RESULTS

Findings suggest that veterans with GWI receiving either yoga or CBT for pain improved following treatment and that changes in biological ANS-especially for the yoga group-moved in the direction of healthy profiles: lower heart rate, higher square root of the mean squared differences between successive R-R intervals (RMSSD), greater parasympathetic activation/dominance (increased high-frequency heart rate variability [HF-HRV], decreased low-frequency/high-frequency [LF/HF] ratio), reduced right amygdala volume, and stronger amygdala-default mode/amygdala-salience network connectivity, both immediately posttreatment and at 6-month follow-up. Biological mechanisms of CBT appeared to underlie improvements in more psychologically loaded symptoms such as self-reported fatigue and energy. Higher tonic arousal and/or more sympathetic dominance (higher skin conductance, lower RMSSD, lower HF-HRV, higher LF/HF ratio) pretreatment predicted greater treatment-related improvements in self-reported ANS for both the yoga and CBT group.

CONCLUSION

These exploratory pilot data provide preliminary support for the suggestion that treatment (yoga, CBT) is associated with improvements in both biological and self-reported ANS dysfunctions in GWI. The major limitation for these findings is the small sample size. Larger and more controlled studies are needed to replicate these findings and directly compare biomarkers of yoga versus CBT.

Current Research on Complementary and Alternative Medicine (CAM) in the Treatment of Anxiety Disorders: An Evidence-Based Review

Complementary and alternative medicine (CAM) encompasses a wide range of different nonmainstream therapies that have been increasingly used for treatment or adjunctive treatment of various ailments with anxiety/anxiety disorders being one of the commonly CAM (self)-medicated conditions. Thousands of published papers refer to use of CAM in various psychiatric disorders or in healthy or medically ill patients with mood or anxiety difficulties. In this chapter we focus specifically on clinically diagnosed (in line with the standard criteria) anxiety disorders and overview evidence of efficacy/safety of a range of CAM modalities: biologically based therapies (typically herbal preparations and less so nutraceuticals); manipulative and body-based therapies (acupuncture, aerobic exercise, massage, therapeutic touch, repetitive transcranial magnetic stimulation, balneotherapy, and others); mind-body therapies (yoga, Morita therapy, Tai Chi, reiki, Chinese cognitive therapy, religious and spiritual interventions, relaxation, mediation, and mindfulness-based interventions); and alternative medical systems (Ayurveda, homeopathy). We focus exclusively on randomized controlled trials and attempt to evaluate the existing body of evidence in the same manner that is applied to mainstream treatments.

A randomized controlled pilot study of the effects of 6-week high intensity hatha yoga protocol on health-related outcomes among students

OBJECTIVE

Modern hatha yoga exercises (YE) provide an alternative form of physical activity which may reduce stress, facilitate recovery and improve health. This study investigated the short-term effects of high intensity hatha yoga exercises (HIY) on health-related outcomes.

METHODS

A 6-week randomized controlled study was performed to compare HIY with a control group not changing their exercise behavior. Healthy students (N = 44; median age: 25 years, range 20-39 years; HIY: n = 21, including 3 men; control group: n = 23, including 3 men) novice to yoga participated in the intervention which included one weekly class and recommended home training. Participants provided self-reports in questionnaires before and after the intervention. Self-reports included anxiety and depression (Hospital Anxiety and Depression Scale), stress (Perceived Stress Scale), sleep quality (Pittsburgh Sleep Quality Index), insomnia (Insomnia Severity Index), subjective health complaints (Common Symptoms in General Practice Index) and self-rated health (single-item).

RESULTS

After the 6-week intervention, there were no between-group differences in anxiety, depression, stress, sleep or self-rated health. However, when investigating associations within the HIY-group, a higher HIY-dose was related to less depression (r = 0.47; p = 0.03), improved sleep quality (r = 0.55; p = 0.01), and less insomnia (r = 0.49; p = 0.02).

CONCLUSIONS

There were no short-term between-group effects of HIY on mental distress, sleep or self-rated health. However, within the HIY-group, a higher dose was associated with improved mental health in terms of depression and with improved sleep. Although future studies with larger samples are needed, these preliminary findings suggest short-term positive effects of HIY on health-related outcomes among students.

Study protocol for a non-inferiority randomised controlled trial of SKY breathing meditation versus cognitive processing therapy for PTSD among veterans

INTRODUCTION

Post-traumatic stress disorder (PTSD) is a debilitating, highly prevalent condition. Current clinical practice guidelines recommend trauma-focused psychotherapy (eg, cognitive processing therapy; CPT) as the first-line treatment for PTSD. However, while these treatments show clinically meaningful symptom improvement, the majority of those who begin treatment retain a diagnosis of PTSD post-treatment. Perhaps for this reason, many individuals with PTSD have sought more holistic, mind-body, complementary and integrative health (CIH) interventions. However, there remains a paucity of high-quality, active controlled efficacy studies of CIH interventions for PTSD, which precludes their formal recommendation.

METHODS AND ANALYSES

We present the protocol for an ongoing non-inferiority parallel group randomised controlled trial (RCT) comparing the efficacy of a breathing meditation intervention (Sudarshan Kriya Yoga [SKY]) to a recommended evidence-based psychotherapy (CPT) for PTSD among veterans. Assessors are blinded to treatment group. The primary outcome measure is the PTSD Checklist-Civilian Version and a combination of clinical, self-report, experimental and physiological outcome measures assess treatment-related changes across each of the four PTSD symptom clusters (re-experiencing, avoidance, negative cognitions or mood and hyperarousal/reactivity). Once the RCT is completed, analyses will use both an intent-to-treat (using the 'last observation carried forward' for missing data) and a per-protocol or 'treatment completers' procedure, which is the most rigorous approach to non-inferiority designs.

ETHICS AND DISSEMINATION

To the best of our knowledge, this is this first non-inferiority RCT of SKY versus CPT for PTSD among veterans. The protocol is approved by the Stanford University Institutional Review Board. All participants provided written informed consent prior to participation. Results from this RCT will inform future studies including larger multi-site efficacy RCTs of SKY for PTSD and other mental health conditions, as well as exploration of cost-effectiveness and evaluation of implementation issues. Results will also inform evidence-based formal recommendations regarding CIH interventions for PTSD.

The Effects of Yoga on Patients with Mild Cognitive Impairment and Dementia: A Scoping Review

Yoga is an ancient mind body practice. Although yoga has been used as a complementary health approach for enhancing wellness and addressing a variety of health issues, little is known about the impact of yoga on cognitive functioning in adults with mild cognitive impairment (MCI) and dementia. We conducted a literature review to examine the impact of yoga on persons with MCI and dementia. Eight studies were identified that reported on yoga as either the primary intervention or one component of a multi-component intervention in samples of persons with MCI or dementia. Results suggest that yoga may have beneficial effects on cognitive functioning, particularly on attention and verbal memory. Further, yoga may affect cognitive functioning through improved sleep, mood, and neural connectivity. There are a number of limitations of the existing studies, including a lack of intervention details, as well as variability in the frequency/duration and components of the yoga interventions. A further complicating issue is the role of various underlying etiologies of cognitive impairment. Despite these limitations, providers may consider recommending yoga to persons with MCI or dementia as a safe and potentially beneficial complementary health approach.

The Daily Influences of Yoga on Relational Outcomes Off of the Mat

Background

Despite the wide array of health benefits that have been evidenced with yoga, a clear gap exists examining how yoga impacts connections with oneself and to others.

Aims

The objectives of the present study were twofold: (1) to describe the day-to-day (in)variability in daily yoga practice and relational outcomes and (2) to examine the direct and indirect effects of yoga practice on relational outcomes.

Methods

Community-dwelling yoga practitioners (n = 104, age range: 18-76 years) with a yoga practice of at least once a week were recruited for a 21-day daily diary study. Practitioners were asked to complete daily Internet surveys at the end of the day which included questions with respect to one's yoga practice and relational domains (i.e., mindfulness, [self-]compassion, and social connectedness).

Results

Multilevel analyses revealed yoga and relational outcomes to be dynamic phenomena, indicated by substantial variation (intraclass correlations = 0.34-0.48) at the within-person level. On days when an individual practiced more yoga than their usual, greater mindfulness (b = 2.93, standard error [SE] = 0.39, P < 0.05) and self-compassion (b = 1.45, SE = 0.46, P < 0.05) were also reported. 1-1-1 multilevel mediation models demonstrated that yoga has an indirect effect on both compassion and social connectedness through increases in mindfulness at the within- and between-person levels. In models testing self-compassion as the mediator, the indirect effect of daily yoga practice on compassion was significant, although limited to the within-person level.

Conclusions

These findings suggest that a routine yoga practice could positively impact how a practitioner relates to theirselves and to others, both on a day-to-day basis, and with accumulated practice.

Yoga for anxiety: A systematic review and meta-analysis of randomized controlled trials

Yoga has become a popular approach to improve emotional health. The aim of this review was to systematically assess and meta-analyze the effectiveness and safety of yoga for anxiety. Medline/PubMed, Scopus, the Cochrane Library, PsycINFO, and IndMED were searched through October 2016 for randomized controlled trials (RCTs) of yoga for individuals with anxiety disorders or elevated levels of anxiety. The primary outcomes were anxiety and remission rates, and secondary outcomes were depression, quality of life, and safety. Risk of bias was assessed using the Cochrane tool. Eight RCTs with 319 participants (mean age: 30.0-38.5 years) were included. Risk of selection bias was unclear for most RCTs. Meta-analyses revealed evidence for small short-term effects of yoga on anxiety compared to no treatment (standardized mean difference [SMD] = -0.43; 95% confidence interval [CI] = -0.74, -0.11; P = .008), and large effects compared to active comparators (SMD = -0.86; 95% CI = -1.56, -0.15; P = .02). Small effects on depression were found compared to no treatment (SMD = -0.35; 95% CI = -0.66, -0.04; P = .03). Effects were robust against potential methodological bias. No effects were found for patients with anxiety disorders diagnosed by Diagnostic and Statistical Manual criteria, only for patients diagnosed by other methods, and for individuals with elevated levels of anxiety without a formal diagnosis. Only three RCTs reported safety-related data but these indicated that yoga was not associated with increased injuries. In conclusion, yoga might be an effective and safe intervention for individuals with elevated levels of anxiety. There was inconclusive evidence for effects of yoga in anxiety disorders. More high-quality studies are needed and are warranted given these preliminary findings and plausible mechanisms of action.

Reasons, Years and Frequency of Yoga Practice: Effect on Emotion Response Reactivity

Yoga practice, even in the short term, is supposed to enhance wellbeing and counteract psychopathology through modification of emotion reactivity. Yoga teaches that emotional responses may be less pronounced with longer and more frequent practice, and potentially when people perform yoga for mental rather than physical reasons. We tested 36 yoga practitioners of varying experience (between 6 months and 11 years of practice). We assessed participants’ self-reported emotional experience and peripheral physiological reactions (heart rate, skin conductance, respiration) when seeing positive and negative pictures. Results were analyzed as a function of the years of, frequency of, and reasons for yoga practice. We found a heart rate increase with the degree participants performed yoga for mental reasons. In addition, years of yoga practice were significantly associated with reduced abdominal respiratory rate when facing negative pictures, speaking in favor of reduced arousal with yoga experience. Finally, regarding frequency of practice, a higher frequency in the last month was linked to less negative and positive experiences as well as a reduced abdominal respiratory amplitude when viewing positive pictures. Altogether, these results demonstrate that intense short-term yoga practice might relate to a (i) decrease in the intensity of self-reported emotional experiences and (ii) deepened respiration. Short-term effects might be shaped by what participants expect as practice benefits. However, several years of practice might be needed to decrease respiratory arousal in the face of negative situations, which likely is a manifestation of an evolution in the emotion regulation process.

Yoga Therapy and Polyvagal Theory: The Convergence of Traditional Wisdom and Contemporary Neuroscience for Self-Regulation and Resilience

Yoga therapy is a newly emerging, self-regulating complementary and integrative healthcare (CIH) practice. It is growing in its professionalization, recognition and utilization with a demonstrated commitment to setting practice standards, educational and accreditation standards, and promoting research to support its efficacy for various populations and conditions. However, heterogeneity of practice, poor reporting standards, and lack of a broadly accepted understanding of the neurophysiological mechanisms involved in yoga therapy limits the structuring of testable hypotheses and clinical applications. Current proposed frameworks of yoga-based practices focus on the integration of bottom-up neurophysiological and top-down neurocognitive mechanisms. In addition, it has been proposed that phenomenology and first person ethical inquiry can provide a lens through which yoga therapy is viewed as a process that contributes towards eudaimonic well-being in the experience of pain, illness or disability. In this article we build on these frameworks, and propose a model of yoga therapy that converges with Polyvagal Theory (PVT). PVT links the evolution of the autonomic nervous system to the emergence of prosocial behaviors and posits that the neural platforms supporting social behavior are involved in maintaining health, growth and restoration. This explanatory model which connects neurophysiological patterns of autonomic regulation and expression of emotional and social behavior, is increasingly utilized as a framework for understanding human behavior, stress and illness. Specifically, we describe how PVT can be conceptualized as a neurophysiological counterpart to the yogic concept of the gunas, or qualities of nature. Similar to the neural platforms described in PVT, the gunas provide the foundation from which behavioral, emotional and physical attributes emerge. We describe how these two different yet analogous frameworks-one based in neurophysiology and the other in an ancient wisdom tradition-highlight yoga therapy's promotion of physical, mental and social wellbeing for self-regulation and resilience. This parallel between the neural platforms of PVT and the gunas of yoga is instrumental in creating a translational framework for yoga therapy to align with its philosophical foundations. Consequently, yoga therapy can operate as a distinct practice rather than fitting into an outside model for its utilization in research and clinical contexts.

Effects of Shambhavi Mahamudra Kriya, a Multicomponent Breath-Based Yogic Practice ( Pranayama), on Perceived Stress and General Well-Being

Stress-induced disorders such as anxiety represent the leading causes of adult disability worldwide. Previous studies indicate that yoga and other contemplative practices such as pranayama, or controlled yogic breathing techniques, may be effective in the treatment of mood disorders and stress. In this study, 142 individuals (mean age = 43 years; SD = 13.90) participated in a 3-day retreat program during which they learned Shambhavi Mahamudra kriya, which is a yogic practice that includes both deep breathing and meditation techniques. Participants were instructed to practice the kriya each day for 21 minutes. After 6 weeks of daily practice, participants reported subjectively lower levels of perceived stress (Perceived Stress Scale) and higher levels of general well-being (General Well-Being Scale) compared to baseline. These results support the notion that Shambhavi Mahamudra kriya may represent a natural treatment for stress reduction.

Improving vasomotor symptoms; psychological symptoms; and health-related quality of life in peri- or post-menopausal women through yoga: An umbrella systematic review and meta-analysis

OBJECTIVES

Vasomotor symptoms (VMS), commonly reported during menopausal transition, negatively affect psychological health and health-related quality of life (HRQoL). While hormone therapy is an effective treatment, its use is limited by concerns about possible harms. Thus, many women with VMS seek nonhormonal, nonpharmacologic treatment options. However, evidence to guide clinical recommendations is inconclusive. This study reviewed the effectiveness of yoga, tai chi and qigong on vasomotor, psychological symptoms, and HRQoL in peri- or post-menopausal women.

DESIGN

MEDLINE, Cochrane Database of Systematic Reviews, EMBASE, CINAHL and the Allied and Complementary Medicine Database were searched. Researchers identified systematic reviews (SR) or RCTs that evaluated yoga, tai chi, or qigong for vasomotor, psychological symptoms, and health-related quality of life (HRQoL) in peri- or post-menopausal women. Data were abstracted on study design, participants, interventions and outcomes. Risk of bias (ROB) was assessed and updated meta-analyses were performed.

RESULTS

We identified one high-quality SR (5 RCTs, 582 participants) and 3 new RCTs (345 participants) published after the SR evaluating yoga for vasomotor, psychological symptoms, and HRQoL; no studies evaluated tai chi or qigong. Updated meta-analyses indicate that, compared to controls, yoga reduced VMS (5 trials, standardized mean difference (SMD) -0.27, 95% CI -0.49 to -0.05) and psychological symptoms (6 trials, SDM -0.32; 95% CI -0.47 to -0.17). Effects on quality of life were reported infrequently. Key limitations are that adverse effects were rarely reported and outcome measures lacked standardization.

CONCLUSIONS

Results from this meta-analysis suggest that yoga may be a useful therapy to manage bothersome vasomotor and psychological symptoms.

A systematic review of yoga for major depressive disorder

BACKGROUND

The purpose of this review was to investigate the efficacy and safety of yoga interventions in treating patients with major depressive disorder.

METHODS

MEDLINE, Scopus, and the Cochrane Library were screened through December 2016. Randomized controlled trials (RCTs) comparing yoga to inactive or active comparators in patients with major depressive disorder were eligible. Primary outcomes included remission rates and severity of depression. Anxiety and adverse events were secondary outcomes. Risk of bias was assessed using the Cochrane tool.

RESULTS

Seven RCTs with 240 participants were included. Risk of bias was unclear for most RCTs. Compared to aerobic exercise, no short- or medium-term group differences in depression severity was found. Higher short-term depression severity was found for yoga compared to electro-convulsive therapy; remission rates did not differ between groups. No short-term group differences occurred when yoga was compared to antidepressant medication. Conflicting evidence was found when yoga was compared to attention-control interventions, or when yoga as an add-on to antidepressant medication was compared to medication alone. Only two RCTs assessed adverse events and reported that no treatment-related adverse events were reported.

LIMITATIONS

Few RCTs with low sample size.

CONCLUSIONS

This review found some evidence for positive effects beyond placebo and comparable effects compared to evidence-based interventions. However, methodological problems and the unclear risk-benefit ratio preclude definitive recommendations for or against yoga as an adjunct treatment for major depressive disorder. Larger and adequately powered RCTs using non-inferiority designs are needed.

The Ottawa panel clinical practice guidelines for the management of knee osteoarthritis. Part one: introduction, and mind-body exercise programs

OBJECTIVE

To identify effective mind-body exercise programs and provide clinicians and patients with updated, high-quality recommendations concerning non-traditional land-based exercises for knee osteoarthritis.

METHODS

A systematic search and adapted selection criteria included comparative controlled trials with mind-body exercise programs for patients with knee osteoarthritis. A panel of experts reached consensus on the recommendations using a Delphi survey. A hierarchical alphabetical grading system (A, B, C+, C, D, D+, D-) was used, based on statistical significance ( P < 0.5) and clinical importance (⩾15% improvement).

RESULTS

The four high-quality studies identified demonstrated that various mind-body exercise programs are promising for improving the management of knee osteoarthritis. Hatha Yoga demonstrated significant improvement for pain relief (Grade B) and physical function (Grade C+). Tai Chi Qigong demonstrated significant improvement for quality of life (Grade B), pain relief (Grade C+) and physical function (Grade C+). Sun style Tai Chi gave significant improvement for pain relief (Grade B) and physical function (Grade B).

CONCLUSION

Mind-body exercises are promising approaches to reduce pain, as well as to improve physical function and quality of life for individuals with knee osteoarthritis.

Effect of yoga on the menstrual pain, physical fitness, and quality of life of young women with primary dysmenorrhea

The aim of the present study was to investigate effect of specially designed yoga program on the menstrual pain, physical fitness, and quality of life (QOL) of non-athlete women with primary dysmenorrhea (PD) aged 18-22 years. Thirty-four volunteers were randomly assigned into control and yoga groups. Menstrual pain, physical fitness, and QOL were evaluated at baseline and at the end of the 12-week study period. The yoga group was asked to practice yoga for 30 min per day, twice a week, for 12 weeks at home, while the control group did not receive any form of exercise over the study period. There were significant improve in menstrual pain, physical fitness, and QOL in the yoga group more than the control group. Therefore, this specially designed yoga program may be a possible complementary treatment for PD.
