Group- plus home-based Tai Chi program improves functional heath among patients with coronary heart disease: a randomized controlled trial

Aims Tai Chi is a promising exercise option in cardiac rehabilitation to manage coronary heart disease (CHD). Increasing attention was paid on home-based cardiac rehabilitation to improve participation rate, but no study has yet emphasized the effect of home-based Tai Chi. A single-blinded randomized controlled trial is used to examine the effects of a group- plus home-based Tai Chi program on functional health. Methods Ninety-eight community-dwelling patients with CHD were randomly assigned to the Tai Chi and control groups. Participants in the Tai Chi group attended 6-week group- plus 6-week home-based Tai Chi program. Outcome measures included physical functions, cardiovascular risk factors, and exercise self-efficacy. Data were collected at baseline, 6-week, 12-week, and 24-week. Intervention effects were analysed using the generalized estimating equation model. Compared with changes in the control group, the intervention group achieved significant improvements in aerobic endurance, Lower-body strength, agility and dynamic balance, diastolic blood pressure, and exercise self-efficacy over the 24-week study period (all P-s<0.05). Intervention adherence was high (79.6% of participants attending >75% of all Tai Chi sessions). Conclusion This Tai Chi program significantly improved the functional health of patients with CHD, indicating that Tai Chi could be taught in group sessions and then continued independently as a home exercise routine for health promotion.
