ABSTRACT:
A continuous passive motion (CPM) device for the synovial joints and surrounding soft tissue of the human body, more specifically to the upper extremities. The device includes an upper arm support suitably fixed to a drive actuator and a adjustable forearm support attached to the rotational center of the drive actuator so that pivotal movement of the output causes the forearm support to pivot about an axis parallel to a longitudinal axis of the forearm support. Various cuffs are provided so a patient can secure their upper arm above the elbow and the upper forearm below the elbow to the device with the actuator located either forward of or behind the elbow. The rotational motion of pronation and supination is created by aligning the rotational center of the actuator output with the anatomical rotational center of the forearm. The rotational centers are concentric to minimize stresses on the affected limb. The relative rotational motion between the upper support and forearm support creates the passive anatomical motion of pronation and supination.
