Effects of Tai Chi on Lung Function, Exercise Capacity and Psychosocial Outcomes in Patients With Chronic Obstructive Pulmonary Disease: Systematic Review and Meta-analysis of Randomized Controlled Trials.

To explore whether tai chi can improve lung function, exercise capacity, and health-related outcomes in patients with chronic obstructive pulmonary disease (COPD). The PubMed, Embase, Cochrane Central Register of Controlled Trials, Chinese National Knowledge Infrastructure (CNKI), Wanfang, and China Science and Technology Journal Database (VIP) databases were searched from inception to January 5, 2023. The methodological quality of the included studies was evaluated according to the Cochrane Handbook for Systematic Reviews of Interventions criteria. A total of 1430 participants from 20 randomized controlled trials were included in this review. The results indicated significant effects of tai chi on FEV1, 6WMD, anxiety, and quality of life ( < 0.01), but not on FEV1%, FEVI/FVC, depression, and social support. Tai chi might be a potential alternative therapy to improve FEV1, 6WMD, anxiety, and quality of life for patients with COPD.
