Palpation: SC/AC/GH joints. Biceps groove, subdeltoid bursa, AC joint and rotator cuff insertion. Check GH for crepitus by palpation of subacromial bursa and passive circumduction
Special tests for: General shoulder instability
o Anterior apprehension: push forwards (anteriorly) on humeral head while externally rotating shoulder passively. Popping or fear of pain/dislocation = positive.
o Relocation test: posterior pressure on humeral head = resolved apprehension (positive)
o Anterior release test: positive if when releasing hand (from postrior pressure above) = pain/apprehension
o Load and shift: compress into glenoid (stabilize) and stabilize scapula then move humeral head anterior/posterior… shift should be < 25% ant and < 50% posterior
o Sulcus: pull arm vertically down (anatomic position), if humeral head slides inferiorly or gap = positive
Special tests for: Glenoid labral pathology
o O’Brien’s: adduct and internally rotate arm, then apply downward pressure against resistance… then repeat w/ externally rotate. Postive = pain with supination, relief with pronation.
o Anterior slide: hands on hips, stabilize clavicle and scapula, push up and forwards on elbow
Special tests for: Rotator cuff tears:
o Drop arm test
o Empty can test: arms 45 degrees, thumbs down, push up against force
o External rotation resistance
o Internal rotation lag: arms behind back, 90 degrees, examiner lifts hand off back. Positive test = patient cannot hold.
o Gerber lift-off test – same set up as internal rotation but patient lifts their hand off back against resistance, pain or cannot lift.
Special tests for: Impingement syndrome:
o Neer’s test: stabalize scapula. Internally rotate and forward flex arm. Anterolateral shoulder pain = positive test.
o Hawkins-Kennedy test – with shoulder and elbow flexed at 90 degrees, passively internally rotate shoulder. Pain = supraspinatus impingement.
o Painful arc test: posive test pain at 60-120 degrees abduction
