Abstract
A continuous passive motion device is provided having specific application to rehabilitative treatment of the elbow or shoulder. The device includes a motorized winch displacable in a first or second direction, a cord suspended from the winch by a variable extension length, which increases when the winch is displaced in the first direction and decreases when the winch is displaced in the second direction, and an arm harness associated with the cord. An arm of a patient is suspended from a suspension point on the cord and the motorized winch is activated to alternately displace the winch in the first and second directions, thereby providing a plurality of repetitive treatment cycles. Each treatment cycle moves the suspension point and correspondingly the elbow or shoulder from a lower treatment limit to an upper treatment limit and back to the lower treatment limit.
