    • The present invention provides continuous passive motion (CPM) devices for joints. An ankle CPM device includes a lower leg support attached at its lower end to a semi-circular track. An actuator slides along the track and can be locked in any desired position on the track. A shaft is pivotally connected at one end thereof to the actuator and a shoe is attached at the other end thereof. When the actuator is positioned at the bottom of the track, the ankle joint of the patient undergoes inversion/eversion motion. When the motor housing is rotated 90° and positioned near the top of the track plantar/dorsi, flexion movement is obtained. A combination of both types of joint movement are obtained for the actuator in intermediate positions. A wrist CPM device includes a brace for the forearm attached to a semi-circular track on which an actuator is mounted. A hand grip is mounted on a semi-circular bracket and a shaft extends between the actuator and a coupling slidably mounted on the semi-circular bracket. With the actuator positioned below the forearm, when the actuator pivots the shaft the wrist joint undergoes ulnar/radial deviation movement and when the motor is rotated 90° and positioned at the side of the arm, extension/flexion movement of the wrist joint is obtained. Positioning the actuator in intermediate positions produces a wrist movement which is a combination of extension/flexion and ulnar/radial deviation of the wrist joint.
