Physical Examination of the Shoulder

Transcription

1 General setup Patient will be examined in both the seated and supine position so exam table needed 360 degree access to patient Expose neck and both shoulders (for comparison); female in gown or sports bra Inspection Skin and tissues: evaluate for bruising, swelling, prior scars, etc. Evaluate for muscle atrophy o Chronic RTC disease o Chronic scapular notch cysts causing nerve impingement o Chronic brachial plexopathy Evaluate for deformity: biceps (popeye deformity), AC joint, SC joint, clavicle, chest wall (pectoralis injury) Evaluate scapular position/winging (wall-pushups will expose this better if suspected) o Marked winging indicates weakness of serratus anterior (long thoracic nerve) o Observe how the scapula tracks with active forward elevation and active abduction Medial border winging laterally is common cause of shoulder impingement pain: Tx with PT for scapular stabilizer strengthening to improve mechanics and decrease impingement pain Palpation for tenderness/crepitus AC joint SC joint Biceps groove Sub-acromial space/bursa Posterior glenohumeral joint line Superior and medial border of scapula- bursitis/snapping scapula

2 Neck Range of motion Scoliosis/kyphosis Tenderness Spurling s sign Passive head rotation toward affected side, with neck extension and compression o Positive if dermatomal radicular pain occurs Shoulder shrug-trapezius strength (spinal accessory nerve-cranial nerve XI) Thoracic outlet syndrome examination: o Roos test Hands held overhead, repeated hand clasps for 1 minute Positive if arm symptoms are reproduced o Adson test Arm extended with neck extension and rotation toward the affected side Positive if loss of radial pulse or symptoms reproduced with inhaling Neurologic exam C5- Deltoid and biceps strength; lateral deltoid sensation; biceps reflex C6- Biceps and wrist extension strength; lateral forearm/thumb sensation; brachioradialis reflex C7- Triceps strength; middle finger sensation; triceps reflex C8- Interossei strength; ulnar forearm/5 th finger sensation; no reflex Shoulder range of motion (bilateral) Six basic shoulder motions are: Elevation (scaption), abduction, adduction, external rotation, internal rotation, extension If stiffness is suspected with active ROM, supine position or sitting position while stabilizing the scapula is more accurate information about true glenohumeral joint range of motion. o Limited AROM and PROM Causes: arthritis, frozen shoulder, deformity/facture o Limited AROM but normal PROM Causes: pain, functional weakness

3 Strength evaluation Rotator cuff testing: o Supraspinatus Jobes test Arm abduction to 90 degrees in scapular plane (30 degrees FE), thumb pointing down, patient resists downward force on arm o If patient has a true drop arm = supraspinatus test o If patient has pain and/or weakness but not a complete drop arm = supraspinatus tear vs. subacromial bursitis Drop sign Same position as Jobes test above, but ask patient to lower arm slowly o If arm drops to their side = supraspinatus tear/dysfunction o Infraspinatus ER weakness with elbow at side and neutral rotation ER lag sign Passively ER arm with elbow at side, and ask patient to maintain ER position o Positive for infraspinatus tear if patient can t hold ER position o Subscapularis Bear hug (superior subscapularis) most specific Affected side hand to opposite shoulder, patient resists examiner bringing hand off of shoulder o Positive if pain or weakness Supine Napolean test (superior subscapularis) most sensitive Supine, examiner holds patients hand flat on abdomen and stabilizes shoulder, patient actively brings elbow forward o Positive if patient can t bring elbow anterior to plan of body Note: not reliable test in patients who have lost significant passive IR due to OA or frozen shoulder (ie. must have normal passive IR for test to be accurate)

4 Strength evaluation, Subscapularis (Continued) o Napolean Belly press (superior subscapularis) palm of hand against abdomen, internal rotation with elbow anterior to plane of body o Positive if elbow can t reach or be maintained anterior to plane of body while palm remains flat on abdomen (patient may cheat by palm coming off of abdomen) Lift off (inferior subscapularis) Dorsum of hand placed on upper lumbar spine o Positive if patient unable to lift hand off of lumbar spine against resistance o Can modify test by passively lifting hand away from lumbar spine and releasing Positive if patient can t maintain hand off lumbar spine Teres Minor ER strength tested at 90 degrees abduction (in scapular plane ie. scaptation) and 90 degrees ER Hornblower s sign positive when arm drifts into IR when put into 90 degrees scaptation and 90 degrees ER Can grade strength out of 5 o 5/5 full o 4/5 weakness detected o 3/5 - able to hold against gravity only o 2/5 can t hold against gravity o 1/5 visible muscle contraction only o 0/5 no muscle contraction Test general upper extremity strength if suspect neurologic process (along with sensation and reflexes)

5 Shoulder stability evaluation Asses for generalized ligament laxity with Beighton scale: 4/9 or greater score suggests hypermobility syndrome: o Thumb-forearm test 0-2 points o 5 th finger hyperextension beyond 90 degrees 0-2 points o Elbow recurvatum beyond 10 degrees 0-2 points o Knee recurvatum beyond 10 degrees 0-2 points o Hands flat on floor with knees extended 0-1 points Sulcus test for inferior capsular laxity (often positive in multi-directional instability/rotator interval disease (seated) o Patient is seated, arm relaxed, examiner pulls down on arm and looks for sulcus off lateral acromion >1cm sulcus that stays with ER at side positive for pathologic rotator interval lesion Anterior and posterior load-shift test (supine) o 40 degrees abduction, 90 degrees FE; examiner applies axial load to the arm along with anterior/posterior forces Positive if increased translation to contralateral side Anterior and posterior apprehension tests (supine) o 90 degrees abduction, >90 degrees ER (maximum) Positive if patient experiences apprehension/feelings of instability (typically anterior) Relocation test posterior force on humeral head in position of apprehension Positive if patient s apprehension is relieved Jerk test (posterior instability) o Sitting position, 90 degrees FE and 90 IR; posteriorly directed force in this position Positive if maneuver causes a clunk or pain

6 Special tests Hawkin s Test shoulder impingement Sitting or standing. Standing lateral or slightly forward of the involved shoulder. Position the shoulder in 90 flexion (in the scapular plane) and elbow in 90 flexion. Support underneath the elbow and grasp the distal forearm on the dorsal surface. Internally rotate the shoulder until pain or limit of range of motion is achieved. Pain or limitation of range of motion due to pain. Indicates pathology of the rotator cuff group (particularly the supraspinatus) or long head of biceps tendon = impingement of these structures under the acromion process. Neer s Test shoulder impingement Sitting or standing. Standing lateral or slightly behind patient. Stabilize scapula with one hand, rotate arm in thumb down position and forward elevate arm. Pain or decreased ROM due to pain. Pain localizes along lateral subacromial space.

7 Cross-body Adduction Test AC joint Seated or standing. At side or behind patient. Position the arm at 90 flexion and then adduct across front of body. Localized pain at AC joint. Speed s Test Biceps Sitting or standing, elbow extended, palm towards the ceiling, with shoulder slightly flexed. Lateral to patient. Palpate the bicipital groove with one hand. Then place other hand over top of distal forearm. Instruct the patient to move arm upward against your resistance, moving through the full range of motion. Pain on the biceps tendon in the bicipital groove or pain in the superior portion of the glenohumeral joint. Indicates inflammation of the biceps tendon, or possible biceps tendinopathy (SLAP lesion)

8 O Driscoll Test SLAP test Seated or standing. Beside or behind patient. Bring arm to abducted and externally rotated position raise and lower arm. Deep seated superior shoulder pain +/- popping. Yergason s Test Sitting or standing, elbow flexed to 90, and forearm midway between pronation and supination (thumb towards ceiling), humerus alongside trunk. Lateral to patient. Palpate the bicipital groove to orient the patient to the location of pain related to the evaluation. Place other hand over top of distal forearm. Instruct the patient to actively flex their elbow and supinate their forearm while examiner resists the motion. Pain or snapping in the bicipital groove or pain in the superior portion of the glenohumeral joint. Indicates tear or laxity of bicipital tendon in groove, or possible bicep tendinopathy (SLAP lesion).

9 O Brien s Test SLAP lesion Seated or standing. Behind or beside patient. Position arm at 90 of flexion, adduct 10 past neutral, with thumbs down. Have patient elevate arm against resistance. Pain at anterior superior shoulder. Repeat test with palm upwards. Pain should be decreased in second position.
