Ch. 13 – The Shoulder and Upper Arm Review of Special Tests Apley’s Scratch Test Drop Arm Test Implications Inability to lower arm in controlled manner is indicative of lesions to the rotator cuff, especially the supraspinatus Apprehension test Implications Anterior capsule, inferior GH L., or glenoid labrum compromised, allowing humeral head to dislocate or subluxate anteriorly on glenoid fossa Gerber Lift-off Test Implications Tears or weakness of subscapularis muscle GH Glide Tests GH Glide Tests Implications – laxity of the static stabilizers of the GH joint Anterior – coracohumeral L., superior and middle GH L., anterior jt capsule, labral tear Posterior – posterior jt capsule, labral tear Inferior-anterior – inferior jt capsule, superior GH L., coracohumeral L. AC Traction Test Implications Sprain of AC or costoclavicular ligaments AC Compression Test Implications Damage to AC L., and possibly coracoclavicular L. Relocation Test Posterior Apprehension Test Implications Laxity in the posterior GH capsule, torn posterior labrum Test for Posterior Instability in the Plane of the Scapula Implications Laxity in posterior GH capsule, coracohumeral L. Sulcus Sign Implications Humeral head slides inferiorly on glenoid fossa, indicating laxity in superior GH ligament Neer Impingement Test Implications – Impingement of rotator cuff and/or long head of biceps tendon between greater tuberosity and inferior side of acromion process and AC joint Hawkins Impingement Test Implications – Impingement of rotator cuff and/or long head of biceps tendon between greater tuberosity and inferior side of acromion process Empty Can Test Implications – the supraspinatus tendon is being impinged between humeral head and coracoacromial arch or is inflamed or contains a lesion Yergason’s Test Implications – snapping or popping = tear or laxity of transverse humeral L.; pain only = bicipital tendinitis Speed’s Test Implications Inflammation of long head of biceps tendon in groove; possible tear of transverse L. with concurrent instability of tendon in groove O’Brien Test Implications – SLAP lesion Adson’s Test Implications Subclavian artery is being occluded between anterior and middle scalene muscles and pec minor Allen Test Implications Pec minor is compressing neurovascular bundle
