a test for bicipital tendon stability in the bicipital groove. It is performed by first having the patient flex their arm to about 90 degrees with the elbow extended and forearm supination. Then apply a downward force as if to place the arm back into neutral position, but instruct the patient to keep the arm flexed. This engages the patient's arm flexors, including the biceps. A positive test is reproduced pain at the bicipital groove.
a test for stability/pathology of the bicipital tendon in the bicipital groove. It is performed by stabilizing the forearm, then flexing the elbow to 90 degrees with the humerus in neutral position then externally rotating the shoulder / supinating the forearm against resistance. The biceps is a muscle involved in supination and this action will mobilize the bicipital tendon. A positive test is pain or the bicipital tendon slipping out of the bicipital groove. Palpation of the bicipital groove during the test will help assess the tendon's stability in the groove.
