Based on pooled data , the diagnostic accuracy of the Neer test for impingement , the Hawkins-Kennedy test for impingement and the Speed test for labral pathology is limited .

The Active Compression Test: A New and Effective Test for Diagnosing Labral Tears and Acromioclavicular Joint Abnormality
Labral tears and acromioclavicular joint abnormalities were differentiated on physical examination using a new diagnostic test . The st and ing patient forward flexed the arm to 90 ° with the elbow in full extension and then adducted the arm 10 ° to 15 ° medial to the sagittal plane of the body and internally rotated it so that the thumb pointed downward . The examiner , st and ing behind the patient , applied a uniform downward force to the arm . With the arm in the same position , the palm was then fully supinated and the maneuver was repeated . The test was considered positive if pain was elicited during the first maneuver , and was reduced or eliminated with the second . Pain localized to the acromioclavicular joint or “ on top ” was diagnostic of acromioclavicular joint abnormality , whereas pain or painful clicking described as “ inside ” the shoulder was considered indicative of labral abnormality . A prospect i ve study was performed on 318 patients to determine the sensitivity , specificity , and positive and negative predictive values of the test . Fifty-three of 56 patients whose preoperative examinations indicated a labral tear had confirmed labral tears that were repaired at surgery . Fifty-five of 62 patients who had pain in the acromioclavicular joint and whose preoperative examinations indicated abnormalilties in the joint had positive clinical , operative , or radiographic evidence of acromioclavicular injury . There were no false-negative results in either group
