ABSTRACT:
A cyclical therapeutic joint exerciser is provided; it alternatively imparts a straightening and bending motion to a desired joint of a patient, e.g., a finger, elbow or knee. The device primarily consists of an inflatable pouch to which a spring steel member is removably attached. The spring or springs maintain the body portion in a flexed, non-extended position when the pouch remains uninflated. As the pouch is inflated, the springs mounted on the pouch, which are normally in a bent position, are extended along with the joint. When the pouch is deflated, the inherent biasing action of the springs causes the pouch and springs to bend, which brings the joint back to the flexed position.
