Efficacy and evidence certainty of traditional Chinese exercises for musculoskeletal disorders: an umbrella review of meta-analyses

Umbrella review of 92 meta-analyses pooling 1,744 randomized controlled trials and 547 outcome associations — the highest tier of evidence on this page. Applying GRADE criteria, 23 associations were rated high-certainty and 179 moderate-certainty; tai chi accounted for 41.5% of the exercise modalities analyzed. High-certainty findings include improved physical function in knee osteoarthritis, significant relief of chronic musculoskeletal pain and stiffness with tai chi, and increased bone mineral density in participants with osteopenia or osteoporosis.

Perception and satisfaction with a Tai Chi-based community cardiac rehabilitation program: a qualitative sub-study of a pilot randomised controlled trial

Qualitative sub-study (interviews with 11 participants, mean age 69, 82% male — Chinese migrants after stent placement or coronary bypass surgery) embedded in a 24-week pilot randomized controlled trial of a community cardiac rehabilitation program integrating virtual tai chi classes. Participants most commonly reported physical improvements, and half reported psychological benefits such as reduced depressive symptoms and improved mood. Peer support, social connectedness, and remote delivery were key facilitators of participation. As a qualitative study, it reports participant perceptions and satisfaction rather than clinical efficacy outcomes.
