The primary goal of performing posterior glides during shoulder rehabilitation is to improve which movement?

• A. Shoulder abduction
• B. Shoulder internal rotation
• C. Shoulder external rotation
• D. Shoulder flexion

Answer: (C)

The primary goal of performing posterior glides during shoulder rehabilitation is to improve shoulder external rotation. This technique is based on the mechanics of the glenohumeral joint, where the convex surface of the humeral head rolls and glides when the arm moves. Posterior glides specifically target the area of the joint that facilitates the movement of external rotation. By applying a posterior glide to the humeral head, the therapist helps to improve the range of motion and restore functional movement patterns necessary for external rotation, which is often limited in individuals with shoulder issues.

Shoulder external rotation is essential for various activities, and any restrictions can impact overall shoulder function. Thus, using posterior glides effectively addresses these limitations and enhances the rehabilitation process for patients recovering from shoulder injuries. This technique does not primarily influence abduction, internal rotation, or flexion, although there might be some secondary benefits to those movements with improved external rotation, the specific focus of posterior glides is on enhancing external rotational capacity.
