The DonJoy Sully Shoulder Support provides shoulder immobilization and controlled range of motion for anterior, multi-directional, inferior and posterior instabilities, rotator cuff deceleration, shoulder AC separations and muscle strains. This shoulder brace is designed to stabilize, assist or restrict movement of the shoulder post-injury and post operatively. The elastic straps attach with Velcro at any point and in any direction. The smooth, controlled assistance or restraint follows the natural movement of the muscles and joints. The perforated breathable, rubber-like neoprene grips the skin so the shoulder support moves with you. The universal design allows you to use this support on either your left or right shoulder.
