Diagnosis
Rotator Cuff Tests
- Supraspinatus Test
- Abduct arm to 90', forward flex it 30' w/ thumb down ("empy beer can position")
- Test for pain/weakness against resistance to continued abduction
- Infraspinatus and Teres Minor Test
- Stabilize the elbow against the patient's waist and bend the elbow to 90'
- Test for pain/weakness against resistance to external rotation
- Subscapularis Test
- Place hand behind lower back
- Test for pain/weakness as patient attempts to push examiner's hand away by moving dorsum of hand away from back
- Drop arm test
- Pt is unable to hold or smoothly lower an extended arm at 90' of shoulder abduction w/o dropping it
Impingement Tests
- Maneuver of Neer
- Prevent scapular rotation w/ one hand while rasing patient's straightened arm in full forward flexion to overhead
- Positive sign is pain in the arc bewtween 70-120'
- Hawkins Impingement Test
- Position the shoulder at 90' of abduction and elbow at 90' of flexion
- Then rotate shoulder internally bringing the arm across the front of the pt
- Positive sign is pain during this maneuver
