Abstract: A shoulder exercising apparatus has a motion assembly defined by a stacked arrangement of first, second and third stages. The first stage is coupled to the second stage to permit relative one-dimensional straightline motion therebetween. The third stage is coupled to the second stage to permit relative in-plane rotational motion therebetween. The motion assembly further includes means for selectively limiting the relative one-dimensional straightline motion and the relative in-plane rotational motion. A handle coupled to the third stage is grasped by a user. A base assembly is coupled to the first stage of the motion assembly for positioning the motion assembly at a selected vertical height, a selected pitch position, and a selected yaw position.

Abstract: A method and adjustable apparatus for stabilizing and strengthening the shoulder muscles and rotator cuff provides an active range of motion activities that can be performed with or without resistance. In particular, the method and apparatus provide for scapular retraction and protraction, shoulder flexion, extension, adduction and abduction, as well as internal and external shoulder rotation, performed horizontally and vertically. All of these motions are beneficial to the shoulder joint because they allow the joint to move freely throughout its normal range of motion using natural mechanics of the rotator cuff and surrounding muscles. The method and apparatus provide the essential benefit of stabilizing the shoulder and rotator cuff throughout these motions so that the user's range of motion and strength building is optimized. The method and apparatus also provide for self myofascial release techniques to decrease spasm.
