Abstract

A hybrid FES/ orthosis system has been developed which includes a long-legged brace with controllable friction brakes at the knee and hip joints. The intent of this system is to achieve acceptable lower limb trajectories by using the stimulated muscles as a source of coarsely regulated power and to regulate this power at each joint through control of the brakes. The orthosis system has been designed and built, and preliminary testing has been conducted on a single paraplegic subject. Results show a significant increase in gait endurance and increase in subject confidence when using the orthosis compared to gait which uses FES alone.
