College of Massage Therapists of British Columbia (CMTBC) Practice Exam

When would a therapist use the Apprehension Crank Test?

1. To assess for rotator cuff tear

2. Suspected anterior GH dislocation

3. To evaluate biceps tendonitis

4. To check for fractures in the shoulder

The correct answer is: Suspected anterior GH dislocation

The Apprehension Crank Test is specifically designed to assess the stability of the glenohumeral (GH) joint, particularly in cases of suspected anterior dislocation. During the test, the therapist positions the patient's arm in a way that places the shoulder in a position that would elicit apprehension or discomfort if an anterior dislocation is present. This involves moving the arm into external rotation and abduction, mimicking the action that would typically lead to a dislocation. If the patient expresses apprehension, it indicates a possible instability or prior dislocation of the GH joint. In contrast, the other options relate to different shoulder pathologies. Assessing for a rotator cuff tear involves tests that evaluate muscle strength and the ability of the rotator cuff to stabilize the shoulder. Biceps tendonitis usually necessitates tests that involve resistance and flexion, focusing on pain elicited in the biceps tendon area. Checking for fractures in the shoulder often requires imaging or other specific physical tests that assess the integrity of bone structures rather than joint stability and apprehension.
