ReWalk comprises a light wearable brace support suit which integrates DC motors at the joint, rechargeable batteries, an array of sensors and a computer-based control system. It fits the body snugly to detect upper body movements, which are used to initiate and maintain the walking process. Wearers also use crutches for stability and safety.
