An assessment of the effects of Iyengar yoga practice on the health-related quality of life of patients with chronic respiratory diseases: a pilot study

Effect of yoga-based exercises on functional capacity, dyspnea, quality of life, depression, anxiety, and sleep of infected healthcare workers during the COVID-19 pandemic: A prospective clinical trial

Objectives

The study aimed to investigate the effect of yoga-based exercises on functional capacity, dyspnea, quality of life, depression, anxiety, and sleep quality following coronavirus disease 2019 (COVID-19).

Patients and methods

Forty-one COVID-19-infected healthcare professionals (35 females, 6 males; mean age: 39.7±6.5 years; range, 28 to 55 years) who were actively working during the subacute period were included in the prospective controlled study between March 2021 and September 2021. The participants were divided into two groups: the yoga-based exercise group (YBEG; n=26) and the nonintervention group (n=15). Besides routine recommendations, the YBEG performed stretching, relaxation, isometric strengthening, breathing, and meditation exercises of 60 min twice a week for eight weeks. Clinical outcome was measured with flexibility tests (shoulder flexibility and sit and reach tests), hand grip strength, 6-min walk test, dyspnea score, Beck Depression and Anxiety Inventory, Short Form 36 (SF-36) quality of life, Pittsburgh sleep quality index (PSQI), and the International Physical Activity Questionnaire (IPAQ) before and after eight weeks in both groups.

Results

Beck anxiety scores, IPAQ scores, PSQI, SF-36 pain, and social functioning subparameters were positively statistically significant in the YBEG (p<0.05). The only parameter found to be insignificant in time and between groups was the SF-36 mental health subparameter (p>0.05). In addition, the YBEG had significant improvements in muscle strength, flexibility, functional capacity, physical activity level, quality of life, anxiety, depression levels, and sleep scores between before and after the eight-week intervention period (p<0.05).

Conclusion

Yoga programs have led to an increase in functional capacity and physical performance, a decrease in anxiety and depression complaints, and an increase in the quality of life in healthcare professionals who were in the process of returning to work during the post-COVID-19.

Effects of Adding Respiratory Training to Osteopathic Manipulative Treatment on Exhaled Nitric Oxide Level and Cardiopulmonary Function in Patients With Pulmonary Arterial Hypertension

Limited research exists regarding nonpharmacologic management of pulmonary arterial hypertension (PAH), except for exercise training. The objective of this study was to investigate the effects of osteopathic manipulative treatment (OMT) alone and combined with respiratory training on fractional exhaled nitric oxide (FeNO), and cardiopulmonary function in patients with PAH. This single-blind, prospective, randomized controlled study included 54 patients with PAH who were randomly allocated to OMT, combined intervention, and control groups. The OMT group (n = 16) and combined intervention group (n = 16) received OMT and yoga respiratory training plus OMT, respectively, twice a week for 8 weeks. The control group (n = 16) received no intervention. All patients undertook an educational lecture. FeNO level, pulmonary function, 6-minute walk distance (6MWD), maximal inspiratory and expiratory pressures, and handgrip strength were assessed at baseline and 8 weeks. Combined intervention and OMT groups significantly improved all outcome measures after 8 weeks of treatment (p <0.01), except mean forced expiratory flow between 25% and 75% of forced vital capacity, which did not change in the OMT group (p >0.05). The control group showed significant deteriorations in 6MWD, inspiratory and peripheral muscle strength, and pulmonary function except peak expiratory flow at 8 weeks (p <0.05). The combined intervention group revealed significantly greater improvements of FeNO, 6MWD, respiratory and peripheral muscle strength, and pulmonary function except mean forced expiratory flow between 25% and 75% of forced vital capacity compared with the OMT group (p <0.05). All outcomes significantly improved in both intervention groups versus the control group (p <0.05). Our study demonstrated that adding respiratory training to OMT provided further benefit to FeNO level and cardiopulmonary function compared with OMT alone and that the OMT might be a useful and safe intervention for patients who cannot attend cardiac rehabilitation programs.

Potential for integrating yoga within pulmonary rehabilitation and recommendations of reporting framework

There is a rising burden of chronic obstructive pulmonary disease (COPD) in India. Pulmonary rehabilitation (PR), is a universally recommended multidisciplinary therapeutic strategy for the management of COPD; however, its needs are unmet. The diversity in the healthcare systems, availability of PR specialists and sociocultural multiformity requires contextualised and innovative PR models. Culturally sensitive elements, such as yoga, have some evidence of a positive impact in the management of COPD. Yoga and PR are based on similar principles with a holistic approach of involving physical activities, behaviour change techniques and psychological support to improve disease outcomes. Arguably the principles of PR and yoga are complementary but there are some important differences in the intensities of activities, exercise types and inclusion of mindfulness in components that must be considered. Components of PR enable aerobic capacity building, strengthening of muscles of the upper and lower extremities and building awareness towards disease management. Yoga, on the other hand, primarily can focus on core strengthening, breathing control, mindfulness and self-awareness. We discuss the potential of integrating the sociocultural appeal of yoga with PR delivered at international standards, and how an integrated approach may lead to optimal referral, uptake and completion.

Evaluating a group-based Yoga of Stress Resilience programme: a pragmatic before-after interventional study protocol

INTRODUCTION

Rates of mental health illnesses and burnout are increasing internationally. Therapeutic yoga is increasingly used to improve and maintain physical, mental and emotional well-being and general health. This protocol describes a study to evaluate the effectiveness of an existing primary care group-based therapeutic yoga programme, the Yoga of Stress Resilience programme, which combines yoga and psychotherapeutic techniques, in improving mental health and decreasing burnout. Implementation factors will also be evaluated for potential scale-up.

METHODS AND ANALYSIS

A pragmatic before-after interventional trial design will be used to study changes in occupational participation and mental health outcomes, including anxiety, depression, burnout, functional impairment, insomnia, perceived stress, loneliness, self-compassion and readiness for change in adults experiencing anxiety and burnout. Repeated measures analysis of variance will be used to determine changes in outcome measures over time. Regression and multivariate analyses will be conducted to examine relationships between participant characteristics and outcomes and among various outcomes. The Reach, Effectiveness, Adoption, Implementation, and Maintenance framework will be used to guide the analyses.

ETHICS AND DISSEMINATION

Approval from the Hamilton Integrated Research Ethics Board has been waived: project number 7082 (full review waived).

Impact of daily yoga-based exercise on pain, catastrophizing, and sleep amongst individuals with fibromyalgia

Background

Fibromyalgia (FM) is a chronic widespread pain disorder characterized by negative affect, sleep disturbance, and fatigue. This uncontrolled pilot study investigated the efficacy of daily yoga-based exercise to improve FM symptoms and explored baseline phenotypic characteristics associated with the greatest benefit.

Methods

FM patients (n=46, with 36 completers) reported psychosocial functioning and a range of FM symptoms using validated instruments before and after participation in Satyananda yoga, which included weekly in-person pain-tailored group classes for 6 weeks and daily home yoga video practice.

Results

Changes in FM symptoms from pre- to post-yoga were variable amongst participants. Group means for pain decreased, as reported by average daily diary and Brief Pain Inventory, with greater home practice minutes associated with a greater decrease in pain. Average daily ratings of sleep and fatigue improved. Pain catastrophizing was decreased overall, with greater change correlated to a decrease in FM symptoms. We did not observe any group mean changes in actigraphy sleep efficiency, Patient-Reported Outcomes Measurement Information System-anxiety and the Revised Fibromyalgia Impact Questionnaire. Multilevel Modeling analysis revealed a significant interaction between anxiety and catastrophizing for end-study sleep efficiency, fatigue, and pain, such that patients with higher baseline catastrophizing and lower baseline anxiety reported less pain and fatigue, and higher sleep efficiency after the sixth week of yoga practice.

Conclusion

This pilot study suggests that yoga may reduce pain and catastrophizing, as well as improve sleep, but these changes were modest across study participants. Greater uptake of home yoga practice as well as a phenotype of higher baseline catastrophizing combined with lower baseline anxiety were associated with greater impact. Future randomized, controlled trials comparing different types of yoga or exercise will allow determination of the most effective treatments for FM and allow closer targeting to the patients who will benefit most from them.

"Smoking Does Not Go With Yoga:" A Qualitative Study of Women's Phenomenological Perceptions During Yoga and Smoking Cessation

INTRODUCTION

Smoking cessation is often accompanied by withdrawal symptoms, cigarette craving, increased negative affect, and increased experience of stress. Because yoga has been shown to reduce stress and negative affect, it may be an effective aid to smoking cessation. The objective of this study was to examine women's phenomenological experiences of vinyasa yoga as part of a smoking cessation program.

METHODS

Focus groups were conducted post-intervention with women (n = 20) who participated in a pilot randomized controlled trial of yoga as a complementary therapy for smoking cessation. The 8-week vinyasa yoga intervention included twice weekly 60-minute classes that involved breathing exercises, postures (asanas), and relaxation techniques. Focus groups were audio recorded and transcribed. Thematic analysis focused on descriptions of yoga, breathing, and bodily sensations including cigarette craving.

RESULTS

Focus group participants described vinyasa yoga as physically challenging. Most reported deliberate use of yogic breathing to cope with cigarette craving and stress. Other perceived effects included relaxation and an increased sense of body awareness and wellbeing.

CONCLUSIONS

Participants viewed yoga as positive and potentially helpful for quitting smoking. Yoga may be an effective adjunct for smoking cessation.

A quick relaxation exercise for people with chronic obstructive pulmonary disease: explorative randomized controlled trial

Background

People with Chronic Obstructive Pulmonary Disease (COPD) suffer from dyspnoea, which may be increased by anxiety. Previous studies suggest that relaxation techniques may have positive effects in pulmonary rehabilitation. The main aim of this study is to explore the clinical impact of a quick, one-session, relaxation training for people with COPD.

Methods

In this perspective, 38 participants with COPD were recruited and randomly assigned to listen to a relaxing audio or to watch a neutral stimulus, during their routine exams. Participants were assessed for psychological and physiological variables, analysed through non-parametric tests.

Results

Those who joined the relaxation training showed more positive outcomes about respiratory and cardiac assessments, as well as for state anxiety and positive affections, in comparison with the baseline and the control group.

Conclusions

Study results suggest that relaxation has a potential to produce improvements in respiratory and cardiac functions, together with a positive emotional effect and a reduction of anxiety.

The relationship of depression in asthma-chronic obstructive pulmonary disease overlap syndrome

Purpose

To clarify the relationship between asthma–chronic obstructive pulmonary disease overlap syndrome (ACOS) and depression.

Methods

We identified 10,911 patients who received an ACOS diagnosis and concurrent treatment between January 2000 and December 2009. Subjects without ACOS were included in the non-ACOS cohort (n = 10,911). Cox proportional hazard regression analysis was performed to compare the risk of depression between the ACOS and non-ACOS cohorts.

Results

The risk of depression was higher in the ACOS cohort than in the non-ACOS cohort (adjusted hazard ratios (aHRs) = 1.67, 95% confidence interval [CI] = 1.48–1.88). In the ACOS cohort, the aHRs for depression were [2.44 (95% CI = 1.45–4.11); 2.36 (95% CI = 1.58–3.52)] in patients [aged 20–39 years; without comorbidity]. In the ACOS cohort, the aHRs for depression were 1.70 (95% CI = 1.51–1.93) and 1.84 (95% CI = 1.55–2.19) in patients without inhaled corticosteroids (ICSs) and oral steroids (OSs) use, respectively. Moreover, the aHRs for the risk of depression were 1.16 (95% CI = 0.95–1.41) and 1.12 (95% CI = 0.96–1.29) in patients with ICSs and OSs use, respectively.

Conclusion

The risk of depression is higher in ACOS patients, even in those without comorbidities or in young adults. The events of the depression were not significant difference in patients receiving the ICSs/OSs between the ACOS and the non-ACOS cohorts.

Yoga-based pulmonary rehabilitation for the management of dyspnea in coal miners with chronic obstructive pulmonary disease: A randomized controlled trial

Background

Coal mine dust exposure causes chronic airflow limitation in coal miners resulting in dyspnea, fatigue, and eventually chronic obstructive pulmonary disease (COPD). Yoga can alleviate dyspnea in COPD by improving ventilatory mechanics, reducing central neural drive, and partially restoring neuromechanical coupling of the respiratory system.

Objectives

To evaluate the effectiveness of Integrated Approach of Yoga Therapy (IAYT) in the management of dyspnea and fatigue in coal miners with COPD.

Materials and methods

Randomized, waitlist controlled, single-blind clinical trial. Eighty-one coal miners (36–60 years) with stable Stages II and III COPD were recruited. The yoga group received an IAYT module for COPD that included asanas, loosening exercises, breathing practices, pranayama, cyclic meditation, yogic counseling and lectures 90 min/day, 6 days/week for 12 weeks. Measurements of dyspnea and fatigue on the Borg scale, exercise capacity by the 6 min walk test, peripheral capillary oxygen saturation (SpO₂%), and pulse rate (PR) using pulse oximetry were made before and after the intervention.

Results

Statistically significant within group reductions in dyspnea (P < 0.001), fatigue (P < 0.001) scores, PR (P < 0.001), and significant improvements in SpO₂% (P < 0.001) and 6 min walk distance (P < 0.001) were observed in the yoga group; all except the last were significant compared to controls (P < 0.001).

Conclusions

Findings indicate that IAYT benefits coal miners with COPD, reducing dyspnea; fatigue and PR, and improving functional performance and peripheral capillary SpO₂%. Yoga can now be included as an adjunct to conventional therapy for pulmonary rehabilitation programs for COPD patients.

The effect of consistent practice of yogic breathing exercises on the human cardiorespiratory system

The purpose of this investigation was to quantify the cardiovascular, respiratory, and cerebrovascular effects of two common yogic breathing exercises (YBE): bhastrika and chaturbhuj; and to determine the effect of their consistent practice on chemosensitivity. The first study was cross-sectional and compared experienced yogic breathers (YB) with matched controls; whereas the second was a 10-week longitudinal training study. The results support four major findings. First chaturbhuj resulted in a hypoxic stimulus in experienced YB compared to control [end-tidal oxygen tension (P_ETO₂), YB: 77.5±5.7mmHg, P<0.05; control: 94.3±12.0mmHg]. Second, performance of chaturbhuj resulted in cyclic oscillations of mean arterial pressure (MAP), heart rate (HR), and middle cerebral artery velocity (MCAv) consistent with the phases of respiration. Third, post training, performance of bhastrika reduced P_ETO₂ (end breath-hold: 90.8 8±12.1mmHg) compared to rest (100.1±7.4, P<0.05); it also resulted in significantly increased MAP at end breath-hold (96.7±13.0mmHg) compared to rest (83.0±6.6mmHg, P<0.05) and significantly increased mean MCAv (end breath-hold: 87.4±23.0cm/s, P<0.05; rest: 55.8±26.3cm/s). Fourth, experienced YB had lower central chemosensitivity than controls (YB: 3.4±0.4; control: 4.6±1.2L/min/mmHg; P<0.05). In conclusion, YBE significantly alter end-tidal gases, resulting in complex oscillations of cardiovascular and cerebrovascular variables, and if practiced consistently, may reduce chemosensitivity.

A randomized controlled study on assessment of health status, depression, and anxiety in coal miners with chronic obstructive pulmonary disease following yoga training

CONTEXT

Psychological comorbidities are prevalent in coal miners with chronic obstructive pulmonary disease (COPD) and contribute to the severity of the disease reducing their health status. Yoga has been shown to alleviate depression and anxiety associated with other chronic diseases but in COPD not been fully investigated.

AIM

This study aimed to evaluate the role of yoga on health status, depression, and anxiety in coal miners with COPD.

MATERIALS AND METHODS

This was a randomized trial with two study arms (yoga and control), which enrolled 81 coal miners, ranging from 36 to 60 years with stage II and III stable COPD. Both groups were either on conventional treatment or combination of conventional care with yoga program for 12 weeks.

RESULTS

Data were collected through standardized questionnaires; COPD Assessment Test, Beck Depression Inventory and State and Trait Anxiety Inventory at the beginning and the end of the intervention. The yoga group showed statistically significant (P < 0.001) improvements on all scales within the group, all significantly different (P < 0.001) from changes observed in the controls. No significant prepost changes were observed in the control group (P > 0.05).

CONCLUSION

Yoga program led to greater improvement in physical and mental health status than did conventional care. Yoga seems to be a safe, feasible, and effective treatment for patients with COPD. There is a need to conduct more comprehensive, high-quality, evidence-based studies to shed light on the current understanding of the efficacy of yoga in these chronic conditions and identify unanswered questions.

Strategies to improve anxiety and depression in patients with COPD: a mental health perspective

Chronic obstructive pulmonary disease (COPD) is a chronic inflammatory lung disease characterized by progressive and only partially reversible symptoms. Worldwide, the incidence of COPD presents a disturbing continuous increase. Anxiety and depression are remarkably common in COPD patients, but the evidence about optimal approaches for managing psychological comorbidities in COPD remains unclear and largely speculative. Pharmacological treatment based on selective serotonin reuptake inhibitors has almost replaced tricyclic antidepressants. The main psychological intervention is cognitive behavioral therapy. Of particular interest are pulmonary rehabilitation programs, which can reduce anxiety and depressive symptoms in these patients. Although the literature on treating anxiety and depression in patients with COPD is limited, we believe that it points to the implementation of personalized strategies to address their psychopathological comorbidities.

Effect of a 10-week yoga programme on the quality of life of women after breast cancer surgery

Aim of the study

The following research is aimed at determining the effect of yoga on the quality of life of women after breast cancer surgery.

Material and methods

A 10-week yoga programme included 90-minute yoga lessons once a week. To estimate the quality of life, questionnaires developed by the European Organisation for Research and Treatment of Cancer (QLQ-C30 and QLQ-BR23) were used. An experimental group consisted of 12 women who practised yoga, a control group – of 16 women who did not. Between groups there were no differences in age, time from operation and characteristics associated with disease, treatment and participation in rehabilitation.

Results

Our results revealed an improvement of general health and quality of life, physical and social functioning as well as a reduction of difficulties in daily activities among exercising women. Also their future prospects enhanced – they worried less about their health than they used to before participating in the programme. As compared to baseline, among exercising women, fatigue, dyspnoea and discomfort (pain, swelling, sensitivity) in the arm and breast on the operated side decreased.

Conclusions

Participation in the exercising programme resulted in an improvement of physical functioning, reduction of fatigue, dyspnoea, and discomfort in the area of the breast and arm on the operated side. Based on our results and those obtained in foreign studies, we conclude that rehabilitation with the use of yoga practice improves the quality of life of the patients after breast cancer surgery. However, we recommend further research on this issue in Poland.
