Taichi is medicine: Effects of Taichi exercise on knee fitness and psychological health in older adults with knee osteoarthritis (KOA): A randomized controlled trial.

BACKGROUND

Knee osteoarthritis (KOA) negatively affects quality of life in older adults, leading to reduced mobility and psychological issues such as depression and anxiety. Taichi, a traditional mind-body practice, may offer therapeutic benefits for this population.

METHODS

A structured Taichi intervention was implemented among older adults with KOA. Pre- and post-intervention assessments evaluated knee function, lower limb strength, balance, and psychological outcomes, including depression, anxiety, and stress. Paired t-tests were used to analyze changes.

RESULTS

This study revealed that The Taichi group showed a statistically significant improvement in knee function (mean difference = 21.6 points, 95% CI: 17.3-25.9, P = .001, Cohen d = 1.87), lower limb strength (mean difference = 24.4 kg, 95% CI: 16.5-32.2, P = .001, d = 1.01), and balance (mean difference = 12.6 points, 95% CI: 2.8-22.3, P = .014, d = 1.01). Psychological outcomes also improved significantly in the intervention group: depression (mean difference = -2.70, 95% CI: -3.71 to -1.69, P = .001, d = 1.06), anxiety (mean difference = -2.28, 95% CI: -3.26 to -1.30, P = .001, d = 0.75), and stress (mean difference = -2.79, 95% CI: -5.19 to -0.39, P = .025, d = 0.61).

CONCLUSION

These findings suggest Taichi as a non-pharmacological intervention for improving both physical and psychological outcomes in older adults with KOA. As a holistic mind-body therapy, Taichi presents a promising approach to enhancing functional ability and mental well-being in this population, reinforcing the concept that Taichi is Medicine.
