Abstract
A continuous passive motion apparatus for improving the healing of patients from operation of the limbs includes a base support plate with a thigh support member pivotally connected to the base and a lower leg support member pivotally connected to the outer end of the thigh support member with flexible drive links connected respectively to the outer ends of the thigh support member and lower leg support member and to a drive variable speed motor having a variable length crank arm with means in the form of pulleys for specifically adjusting and altering the direction of motion of the flexible drive links. The speed and length of the motions can be separately and independently adjustable by selective adjustment of the drive motor, crank arm and the respective drive links. An alternate embodiment utilizes a guide track in place of one link for guiding the outer end of the thigh support member. The method includes the continuous movement of a limb within specific selected ranges and duration for the improvement of the healing process as well as enhancing the mobility of the limb upon healing. There is an additional beneficial effect upon venous circulation in the limb which may influence the incidence of postoperative thromboembolic disease.
