Abstract
- OBJECTIVE: To determine the feasibility of a randomized controlled trial of the effect of a tai chi program on quality of life and exercise capacity in patients with COPD. METHODS: We randomized 10 patients with moderate to severe COPD to 12 weeks of tai chi plus usual care (n = 5) or usual care alone (n = 5). The tai chi training consisted of a 1-hour class, twice weekly, that emphasized gentle movement, relaxation, meditation, and breathing techniques. Exploratory outcomes included disease-specific symptoms and quality-of-life, exercise capacity, pulmonary function tests, mood, and self-efficacy. We also conducted qualitative interviews to capture patient narratives regarding their experience with tai chi. RESULTS: The patients were willing to be randomized. Among 4 of the 5 patients in the intervention group, adherence to the study protocol was excellent. The cohort's baseline mean ± SD age, percent-of-predicted FEV<subscript>1</subscript>, and ratio of FEV<subscript>1</subscript> to forced vital capacity were 66 ± 6 y, 50 ± 12%, and 0.63 ± 0.14, respectively. At 12 weeks there was significant improvement in Chronic Respiratory Questionnaire score among the tai chi participants (1.4 ± 1.1), compared to the usual-care group (−0.1 ± 0.4) (P = .03). There were nonsignificant trends toward improvement in 6-min walk distance (55 ± 47 vs -13 ± 64 m, P = .09), Center for Epidemiologic Studies Depression Scale (−9.0 ± 9.1 vs −2.8 ± 4.3, P = .20), and University of California, San Diego Shortness of Breath score (−7.8 ± 3.5 vs −1.2 ± 11, P = .40). There were no significant changes in either group's peak oxygen uptake. CONCLUSIONS: A randomized controlled trial of tai chi is feasible in patients with moderate to severe COPD. Tai chi exercise as an adjunct to standard care warrants further investigation. (ClinicalTrials.gov registration NCT01007903) [ABSTRACT FROM AUTHOR]
