ABSTRACT:
A continuous passive motion device for achieving full extension of the leg of a patient includes a base and a four-bar articulated limb support member which is mounted for movement on the base. For the articulated limb support member one bar is a femoral support member which is pivotally mounted on the base. Another one of the bars is a tibial support member which is pivotally joined to the femoral support member. Also included in the device is a drive bar which has a first end reciprocally mounted on the base of the device and a second end which is pivotally attached to the femoral support member. A cross bar having a first end pivotally attached to the tibial support member and having a second end pivotally attached to the drive bar interconnects the tibial support member and the drive bar. The device further includes a motor which is connected to the device for reciprocating the first end of the drive bar to alter the configuration of the device for exercising the leg. A method is disclosed for passively exercising the leg of a patient, using the above described device.
