This study was designed to investigate the effects of Tai Chi training on moderate to severe Chronic obstructive pulmonary disease (COPD) in the stable phase. This was a 2-arm randomized clinical trial. A total of 226 COPD patients with moderate to severe in the stable phase were allocated to either the control group or the observation group. The observation of the frequency of acute exacerbation for both groups lasted for at least 52 weeks follow-up. Changes in lung function and symptom scores of health-related quality of life (St George’s Respiratory Questionnaire score) were also compared between the 2 groups. The accompanying anxiety and depressive symptoms of the patients were evaluated using the Self-Rating Depression Scale and Self-Rating Anxiety Scale prior to the procedure and 52 weeks later. Patients with moderate to severe COPD in China were divided into the Tai Chi group (n = 116) or control group (n = 110). After excluding 10 patients who fell off, 108 patients were enrolled in each group. Evidently, the matched group had higher exacerbation rate than the Tai Chi group (Chronic obstructive pulmonary disease (COPD) is a widespread, preventable and treatable disease, characterized by persistent airflow limitation makes a significant contribution to morbidity and mortality, which causing serious social and economic burdens globally.In China, Tai Chi has been a common practice for Chinese people to exercise their minds and bodies for many centuries. Long-term Tai Chi exercises have been confirmed to contribute to the improvement of physical function, exercise capacity, and psychological state, which helps in the treatment of chronic diseases.Therefore, the goal of this study was to determine the benefits of Tai Chi in preventing COPD acute exacerbations in patients with COPD.
