Neer Impingement Test: Scapula is stabilized by the examiner, and arm is elevated into flexion by the examiner until report of pain. A positive test is pain in the anterior or lateral shoulder between 90 and 140 degrees. Sensativity: 68%, Specificity: 68%
Hawkins Kennedy: Passively flex the patients arm to 90degrees within the plane of the scapula, stabilize the elbow which is bent to 90dgrees and internally rotate the shoulder. Sensativity: 71.5%, Specificity: 66%
Painful arc: The patient elevates their arm in the scapular plane actively and complains of pain between 60 and 120 degrees. Sensativity: 73.5%, Specificity: 81%.
Jobes Supraspinatus Test: Manual resistance is applied to the arm with the the shoulder elevated to 90 degrees in the scapular plane with internal or neutral rotation. Sensativity: 44%, Specificity: 89.5%
Infraspinatus muscle strength test: Elbow is flexed to 90degrees and the arm is adducted to neutral. Manual pressure is applied into internal rotation and the patient resists into external rotation. A postive test is giving way. Sensativity: 41.6%, Specificity: 90.1%.
Drop arm test: The patient is asked to elevate (or examiner passively elevates) arm fully and then is asked to hold and then slowly lower that arm. A + test is if the arm drops suddenly or if the patient has severe pain holding it. Sensativity: 26.9%, specificity: 88.4%.
A combination of a + Hawkins Kennedy, + Painful arc and + infraspinatus strength test have a + likelihood ratio of 10.56 for having any degree of subacromial impingement.
A combination of a + Drop arm, + Painful arc and + infraspinatus strength test have a + likelihood ratio of 15.57 for having a full thickness RTC tear.
