ABSTRACT:
A shoulder rehabilitation and exercise device is disclosed which enables a user to perform internal and external rotations of both right and left shoulder. The device is comprised of a base plate, hydraulic damper, restrictor arm, actuator arm, elbow cup and hand grip. A smooth, fluid-like movement is achieved during performance of arcuate internal and external shoulder rotations while also providing automatic increases and decreases in resistance to such motion in response to user effort. In certain preferred embodiments, in addition to such automatic adjustment of resistance, the device includes a means of manually adjusting resistance. The device may be utilized to perform the aforementioned internal and external rotations on a user's right or left side without need for making any adjustments to the machine. Range of motion limitations may be set to control the arcuate degree of internal and external rotations performed. Adjustment in the elevation of a user's forearm via adjustment of the actuator arm is provided. The actuator arm includes an adjustable elbow cup and adjustable hand grip. The device does not store potential energy or produce sufficient momentum to oppose a user's immediate and safe termination of motion.
