  This project is designed to identify the biomechanical mechanisms of Tai Chi (TC) exercise and test a novel TC intervention by modifying newly identified mechanisms for those with knee osteoarthritis (OA) and to assess the changes in pain associated with the intervention. It combines unique real time torque biofeedback approach, and uses external knee adduction moment (EKAM) as modulation target tailored to TC intervention in this population. The potential benefit from this project is to provide biomechanical insights of TC and this novel TC approach may produce meaningful pain reduction in these patients who can learn and practice safely during this intervention.
