Yergason’s Test, a common test in orthopedic examination of the shoulder, is commonly used to determine pathology in the biceps tendon.
- biceps tendon
- glenoid labrum
- transverse humeral ligament
The test is usually easier in sitting or standing. On the side to be tested the one of the examiner’s hands palpates the bicipital groove. The arm to be tested is relaxed at the person’s side. The elbow is flexed to 90 degrees and the forearm is in neutral position or is pronated.
The examiner’s other hand applies downward pressure on the patient’s forearm (attempt to extend the patient’s elbow) while also attempting to move the patient’s forearm into further pronation. The patient forcefully resists these movements.
Yergason’s Test is considered positive for bicipital tendinopathy if there is pain in the area of the bicipital groove. The test is positive for transverse ligament pathology if there is a snapping of the bicipital tendon.
Accuracy of Test
The test accuracy is questionable; pain may be result of multiple different structures including the structures of the rotator cuff. The test can also appear positive when the pathology is related to the glenoid labrum; e.g. SLAP lesion.
