Personalized foot progression angle modifications led to a significant 1.2-point greater reduction in medial knee pain over one year compared to sham gait retraining.
Intervention decreased the peak knee adduction moment—a biomechanical marker linked to medial knee load—with a significant between-group difference (P = .0001).
Magnetic resonance imaging (MRI) revealed slowed progression of cartilage degeneration in the medial femoral compartment in the intervention group as evidenced by smaller increases in T1rho relaxation times.
The trial demonstrated safety and feasibility of gait modification with vibrotactile biofeedback and structured retraining sessions.
