Shoulder Orthosis

A shoulder orthosis is a device designed to support, stabilize, or restrict movement of the shoulder joint, the glenohumeral joint, to aid with healing, improve function, or prevent injury. These orthoses are commonly used following trauma, surgery, or in neurological conditions like stroke, where muscular control and joint integrity may be compromised.

One of the key applications of the shoulder orthoses is in managing shoulder instability, which can result from ligament laxity, dislocations, or muscle weakness. In these cases, shoulder orthoses limit excessive or abnormal movements, maintain proper alignment, and provide proprioceptive feedback to enhance joint control. Orthoses such as shoulder stabilizing braces or neoprene compression garments are commonly used in athletes or individuals recovering from shoulder dislocation to prevent recurrence and promote stability.

In stroke patients, especially those with hemiplegia or hemiparesis, shoulder subluxation (partial dislocation of the glenohumeral joint) is a frequent complication due to weakness or paralysis of the shoulder stabilizing muscles. This can cause pain, limit functional use of the arm, and impair recovery. A shoulder support orthosis often in the form of a humeral cuff sling helps maintain glenohumeral alignment, reduce the gravitational pull on the shoulder, and minimize subluxation.
