ABSTRACT:
A continuous passive motion physical therapy device for passively exercising the muscle groups especially surrounding the lumbar spine for postoperative and other rehabilitative therapy. An improved pivoting support displacement device, comprised of first and second actuators, for oscillating at least one pivoting support member is provided. The first actuator is associated with the upper torso support member and includes an output cam for imparting substantially linear motion to a connecting rod. The connecting rod is pivotally secured to one end of the output cam and at a selected location to an actuator cam. The actuator cam is secured to the axle to which is releasably secured a displacement cam. A push rod is releasably and pivotally secured between the displacement cam and the upper torso support member. The second actuator is associated with the lower body support member and includes an actuator cam and a displacement cam, each being substantially similar to those of the first actuator. Further, the second actuator includes a second connecting rod having opposite ends thereof pivotally connected to the distal ends of the actuator cams of the first and second actuators. Thus, as the actuator cam of the first actuator is oscillated, the actuator cam of the second actuator is simultaneously oscillated.
