A capacitive biofeedback sensor including a polyurethane dielectric sandwiched between two wire mesh or carbon impregnated silicone rubber conductors. The sensor is placed within a patient\s shoe, boot, ankle, brace, crutch, hand grip, wheelchair, etc., and provides biofeedback to help patients relearn function or prevent complications that impede function.
