Apprehension Test

Other Names Crank Test
Examination type Joint stability
Patient & Body Segment Positioning Patient lies supine on a table with the involved shoulder abducted to 900 and the elbow flexed to 900
Examiner Position Examiner stands beside the athlete with one hand under the elbow to support the arm and act as a fulcrum and the other hand on the athlete’s wrist to externally rotate the shoulder.
Tissues Being Tested Glenoid Labrum, inferior glenohumeral ligament
Performing the Test With the subject’s involved shoulder in 90 degrees of abduction and the elbow in 90 degrees of flexion, the examiner slowly externally rotates the shoulder by placing a downward force on the patient’s wrist.
Positive Test Apprehension of the patient toward further movement into external rotation direction or pain. The examiner may also notice anterior translation or subluxation of the humeral head.  This test is used to mimic the positioning and movement of an anterior dislocation of the glenohumeral joint, thus recreating a subject’s episode of instability.
Interpretation Anterior instability of the glenohumeral joint.
Common errors in performing exam Externally rotating or “cranking” the shoulder too quickly can cause excessive apprehension, pain, or anterior subluxation of the humeral head.
Factors possibly resulting in misinterpretation Shoulder impingement can also cause the Apprehension test to be positive.
