ABSTRACT:
One embodiment is an upright, height adjustable, vertical stand having a freely rotatable elbow and forearm stabilizer, in the form of a receiving cup mounted on its top. The receiving cup is L-shaped, concave, and contoured to receive the elbow of a user, and includes a portion which is parallel to the axis of the forearm of a user, and a portion of the upper arm of a user to secure the upper and lower arm at a 90.degree. angle to one another, which results in the isolation of the rotator cuff muscles at the shoulder joint at any plane of movement. A pivot arm extends from the cup, and includes a hand receiving device adjacent to its end. The device may include a mechanism which allows internal and external shoulder rotation range of motion to be measured, as well as a device by which internal and external shoulder rotation range of motion can be limited. It can be used either without resistance, or with resistance from an external source. A mechanism which allows for adjustable settings of the plane at which the forearm is held during internal and external shoulder rotation may be provided. Various embodiments allow the pivot arm to be extended horizontally, vertically or at an angle from the vertical. In one embodiment a two station device is provided.
