The apprehension test is used to assess which aspect of the shoulder?

• A. Posterior glenohumeral instability
• B. Anterior glenohumeral instability
• C. Rotator cuff tear
• D. AC joint separation

Answer: (B)

The test is used to assess anterior instability of the glenohumeral joint. By positioning the arm in abduction with external rotation, you stress the anterior structures of the shoulder. If the patient shows apprehension, fear that the shoulder will dislocate, or protective guarding, that suggests the humeral head is unstable in the anterior direction. A relocation maneuver—gently applying a posterior force to the humeral head while maintaining the position—can reduce this apprehension and reinforces that anterior instability is present, often pointing to injury of the anterior capsule or a Bankart lesion. This targeted test isn’t about posterior instability, which is evaluated with different maneuvers, nor is it a primary test for rotator cuff tears or AC joint injuries, which have their own distinct signs and provocative tests.
