BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a major public health problem worldwide. However, several studies that have assessed the role of traditional Chinese exercise in the management of this disease include broad variations in sample sizes and results. Therefore, this meta-analysis was conducted to assess the effects of traditional Chinese exercise on patients with COPD. METHODS: Two investigators independently identified and extracted data from selected articles. A computerized search of electronic databases through August 2015 was conducted. Mean differences (MDs) and 95% confidence intervals (CIs) were calculated to analyze the combined data. The methodological quality was evaluated using the Cochrane risk-of-bias tool. Heterogeneity was assessed with the I2 test. RESULTS: Ten randomized, controlled trials (RCTs) involving 622 patients met the inclusion criteria. There were significant improvements in the 6-minute walking distance test (6 MWD; MD 12.10m; 95% CI 7.56 to 16.65 m; p < 0.001); forced expiratory volume in one second (FEV1% predicted; WMD 9.02; 95% CI 6.80 to 11.23; p < 0.00001); forced expiratory volume in 1 second/forced vital capacity (FEV1/FVC) ratio (Tiffenau Index WMD 6.67; 95% CI 5.09 to 8.24; p < 0.00001); and quality of life, as evaluated by the Chronic Respiratory Disease Questionnaire (CRDQ; WMD 0.85 score; 95% CI 0.52 to 1.18; p < 0.00001). CONCLUSIONS: Traditional Chinese exercise could provide an effective alternative method for managing COPD. Larger and higher-quality trials are required.
