Abstract
A device for exercising an articulated limb such as a finger includes an elastomeric element for biasing the finger to a flexed position and a motorcontrolled cable is provided to oppose the flexion bias. The elastomeric element, motor, and cable are carried on the arm by a splint. A feed mechanism is provided for regulating the length of cable, which in turn regulates the degree of flexion and extension. The feed mechanism includes a motor having an automatic mode which continuously reverses motor operation when programmed flexion and extension limits are reached. An overtravel is provided to maintain a constant tension on the cable should a sudden extension of the finger prevent proper cable feed or take-up.
