In the shoulder posterior glide joint mobilization for internal rotation, what is the direction of the applied force?

• A. Anterior
• B. Posterior
• C. Superior
• D. Inferior

Answer: (B)

Posterior glide mobilization for internal rotation uses a force directed toward the back of the shoulder. Since the humeral head is convex on the concave glenoid, the glide direction is opposite the direction of the desired movement. To increase internal rotation, you push the humeral head posteriorly, producing a posterior glide that frees the joint to rotate inward more readily. The other directions would bias different motions (anterior for external rotation, etc.), so posterior is the targeted direction here.
