Comparative efficacy of Tai Chi versus balance training on functional performance and postural control during sit and stand transitions in individuals with knee osteoarthritis: A randomized trial.

Study Summary

69 patients with knee osteoarthritis were randomized to receive Tai Chi training or balance training for 12 weeks. The primary outcomes of interest were centre of mass displacement and velocity, trunk flexion angle, knee extension moment, and movement duration during sit-to-stand and stand-to-sit transitions. Secondary outcomes of interest included Knee Injury and Osteoarthritis Outcome Score (KOOS) for pain, symptoms, activities of daily living, sport and recreation, quality of life, and total scores. Outcomes were assessed before and after the 12-week intervention. Overall, the results of the study revealed that Tai Chi and balance training produced comparable improvements in sit-to-stand and stand-to-sit performance, postural control, and knee-related symptoms and function. These findings suggest that both interventions are viable exercise options for improving functional mobility and postural control in individuals with knee osteoarthritis.
