Effects of yoga on depressive symptoms, anxiety, sleep quality, and mood in patients with rheumatic diseases: Systematic review and meta-analysis.

OBJECTIVE: To investigate the effects of yoga on depressive symptoms, anxiety, sleep quality, and mood of patients with rheumatic diseases through a systematic literature review with meta-analysis. LITERATURE SURVEY: This review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement and the Cochrane recommendations and risk of bias tool. The study was registered in the International Prospective Register of Systematic Reviews (PROSPERO). Studies were selected using the PICOS (participants, intervention, comparison, outcome, and study) strategy. Searches were carried out until March 2022 and performed in Web of Science, PubMed, SportDiscus, Scopus, Cochrane, and EBSCO databases. METHODOLOGY: Data were extracted to identify the differences between yoga and control and exercise groups and effect sizes. SYNTHESIS: In total, 27 studies were included for qualitative analysis and 18 for meta-analysis. The studies found investigated yoga in patients with osteoarthritis, fibromyalgia, rheumatoid arthritis, and chronic fatigue syndrome. Regarding the risk of bias, the majority of studies showed a high risk or uncertain risk of bias in several criteria. Regarding the meta-analysis, yoga was favored to decrease depressive symptoms (standard mean difference [SMD]:-0.88; 95% confidence interval [CI]:-1.42; -0.34), anxiety (SMD: -0.51; 95% CI = -0.81 to -0.20), and improve sleep quality SMD = -0.96; 95% CI = -1.36 to -0.56). No differences were found between yoga and other exercise modalities in depression (p < .01). CONCLUSIONS: Yoga is effective in improving depression, anxiety, and sleep quality of patients with rheumatic diseases. However, research in this field still needs further studies, because of methodological issues in the studies and a reduced number of studies conducted on each rheumatic disease and on the effects of yoga on each variable.

Preferred exercise and mental health of the patients with fibromyalgia syndrome.

BACKGROUND AND PURPOSE: Preferred exercise may be beneficial for the mental health of patients with fibromyalgia syndrome (FMS).This study aimed to investigate the effects of preferred exercise on the quality of life (Qol), depression, and mood states of the patients with FMS. MATERIALS AND METHODS: This study was a nonrandomized controlled trial. The patients with FMS were divided into an experimental group (EG; n = 22) and a control group (CG; n = 14). The patients in the EG performed their preferred exercise (resistance, walking, or stretching) for 12 weeks. CG went to a waiting list. Fibromyalgia Impact Questionnaire, Beck Depression Inventory, and Brunel Mood Scale were used to evaluate the outcomes. RESULTS: The EG exhibited a decrease in the total impact of FMS on the Qol, depression, tension, and mental confusion (p < 0.01). CONCLUSION: Preferred exercises reduced the impact of FMS on the Qol, depression, and mental confusion of patients with FMS.

Effect of yoga on the quality of life of patients with rheumatic diseases: Systematic review with meta-analysis.

AIM: To analyze the effects of yoga on the quality of life of patients with rheumatic diseases through a systematic review with meta-analysis. METHODS: This systematic review with meta-analysis was conducted following the recommendations of the Declaration of PRISMA. The searches were carried out on the databases PubMed, Web of Science, EBSCO, Scopus, and Cochrane until August 2018. Experimental studies evaluating the effect of yoga on the quality of life in patients with rheumatic diseases were included. RESULTS: After data searches, 483 studies were found, 23 of which were included in our analysis. We found that yoga improves the overall quality of life (d= -0.64; 95% CI: -0.91 to 0.038) of patients with rheumatic diseases, as well as the following domains: functional capacity (d = 16.43; 95% CI: 13.37-19.49), physical aspects (d = 27.11; 95% CI: 19.40-34.83), emotional aspects (d = 26.00; 95% CI: 18.87-33.13), general health (d = 16.61; 95% CI: 12.66-20.55), and social aspects (d = 7.01 ; 95% CI: 5.57-9.45). CONCLUSION: Evidence suggests weak recommendations can be made for the use of yoga in the management of RD patients.
