To improve glenohumeral external rotation using joint mobilizations, a physical therapist should focus on which technique?

• A. Anterior glides
• B. Posterior glides
• C. Lateral glides
• D. Circumferential glides

Answer: (B)

To enhance glenohumeral external rotation through joint mobilizations, focusing on posterior glides is essential. The glenohumeral joint is a ball-and-socket joint, and external rotation involves the movement of the humeral head in the glenoid cavity. When conducting posterior glides, the therapist applies a force toward the posterior aspect of the humeral head, facilitating an increase in the available range of motion in external rotation.

This technique is particularly effective because it targets the structures that can restrict this particular motion, such as the anterior capsule and surrounding ligaments. By mobilizing the joint posteriorly, the therapist can effectively reduce stiffness and improve the mobility required for external rotation.

In contrast, anterior glides are more appropriate for improving internal rotation and flexion range, while lateral glides primarily assist in addressing issues related to abduction. Circumferential glides, although beneficial for overall joint health and maintenance, do not specifically target the limitations in external rotation as effectively as posterior glides do. Thus, employing posterior glides is the most strategic approach to achieve the desired outcome in external rotation enhancement at the glenohumeral joint.
