Shoulder instability is characterized by the inability of the structures surrounding the shoulder joint to keep the ball tightly within its socket. If the joint is too loose and slides partially out of place, this is called shoulder subluxation. If it slides completely out of place, shoulder dislocation has taken place. Individuals suffering from the condition may complain of a sensation that their shoulders are about to slide out of place – a feeling referred to as “apprehension” by physicians. One of the main risk factors for this condition is having experienced a previous shoulder dislocation, as this can damage the ligaments of the shoulder and thus adversely affect their ability to hold the joint in place. A shoulder support can treat this condition by restricting the movement of the shoulder joint and allowing those ligaments to heal.
