Abstract: A brace for supporting a wearer's shoulder joint during movement is made of elastic material and comprises a torso strap, a shoulder strap, upper and lower stabilizing straps and a vertical support strap. The torso strap is securable around the torso of the wearer generally across the lower end of the rib cage. The shoulder strap is secured at a first end to the torso strap on a side opposite the shoulder to be supported. The shoulder strap extends across the front of the wearer, over and around the shoulder to be supported and across the back of the wearer and is removably securable at a second end to the torso strap along the side opposite the supported shoulder. The shoulder strap is secured to the torso strap under tension to provide the desired support to the shoulder. The upper and lower stabilizing straps cooperate with the shoulder strap to form a shoulder receiving pocket in the shoulder strap and help hold the shoulder strap in place.
