Tai Chi exercise was beneficial for ameliorating physical and mental health of patients with knee osteoarthritis and should be available as an alternative non-pharmacological therapy in rehabilitation programmes.
A total of 16 RCTs involving 986 patients with knee osteoarthritis met the established inclusion criteria. The strength of evidence for the main outcomes was low or moderate. The systematic review illustrated the efficacy of Tai Chi exercise in treating and managing knee osteoarthritis. Patients’ outcomes practising Tai Chi exercise were improved significantly, including pain, stiffness, physical function, dynamic balance, physiological and psychological health. No adverse events associated with Tai Chi exercise were reported.
