Background
Although several studies have assessed the effect of Tai Chi in management of chronic
obstructive pulmonary disease (COPD), these studies have a wide sample variation and
convey inconclusive results. This study aims to determine if a 3-month Tai Chi program
improves lung function, exercise capacity, and health related quality of life (HRQoL)
in people with COPD.
Methods
A randomised controlled, single blind trial was undertaken. Patients were randomly
allocated to either Tai Chi group (n = 26) or control group (n = 24). Participants in the Tai Chi group received a Tai Chi exercise program three times
weekly for 3-months while participants in the control group were advised to maintain
their routine activities. Outcome measures included lung function, 6-minute walk distance
(6WMD) and COPD Assessment Test (CAT). The measurements took place at baseline and
immediately after the 3-month intervention period.
Results
Of 50 participants, 46 completed the intervention. Compared to control, Tai Chi significantly
increased 6WMD (mean difference 60.5m, 95% CI 30.27–78.69), and reduced score of CAT
(mean difference 14 points, 95% CI 11–24). An 86% compliance to the Tai Chi training
was noted and no adverse events were observed in Tai Chi group.
Conclusions
The Tai Chi program is a safe, effective and feasible method to improve exercise capacity
and health-related quality of life in people with COPD.
