OBJECTIVE: the aim of the study is 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 PRISMA Statement and the Cochrane recommendations and risk of bias tool. The study was registered in the PROSPERO. Studies were selected using the PICOS 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 in order 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 osteoarthritis, fibromyalgia, rheumatoid arthritis, and chronic fatigue syndrome patients. 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 (SMD:-0.88; CI95%:-1.42;-0.34), anxiety (SMD- 0.51; 95%CI = -0.81 to -0.20), and sleep quality =-0.96; 95%CI = -1.36 to -0.56). No differences were found between yoga and other exercise modalities in depression (p<0.01).
CONCLUSIONS: Yoga is effective in reducing depression, anxiety, and sleep of patients with rheumatic diseases. However, research in this field still needs further studies, due to 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.
