The effect of Tai Chi on influence in patients with Osteoarthritis of the knee

OBJECTIVE: To investigate the effects of Tai Chi practice on muscle strength, pain sensation, and function improvement in patients with knee osteoarthritis, using Tai Chi as an interfering factor. METHODS: Thirty eligible subjects were randomly divided into an experimental group and a control group for a 16-week trial. The experimental group practiced Tai Chi, while the control group received no intervention. All subjects underwent VAS, KOOS, and Biodex isokinetic muscle strength tests before and after training. RESULTS: There were significant differences in VAS scores between the experimental and control groups. In the KOOS score, significant differences were only observed in the "symptoms and stiffness" and "pain" dimensions. Significant differences were also observed at a relative peak torque angular velocity of 60°/s during isokinetic knee extension. CONCLUSION: Tai Chi has an improving effect on lower limb muscle strength, symptoms and stiffness, and pain relief in patients with knee osteoarthritis.
