Clinical trials: Lower Extremity Biomechanics
Ankle Fractures, Post-traumatic Osteoarthritis
Iterative Design of Custom Dynamic Orthoses to Reduce Articular Contact Stress
The proposed study evaluates the effect of carbon fiber brace design on forces across the ankle joint. Research suggests that ankle arthritis develops after ankle fracture, in part, due to elevated forces on the cartilage.
