Ch 4 Physical Exam Upper Extremity Flashcards
Palpation of the upper extremity includes:
Acromioclavicular joint
Subacromial bursa
Long head of the biceps
Normal shoulder motion is a composite movement that couples:
Glenohumeral motion with movement of the scapula on the thorax
Scapular movement is derived from motion of the:
Acromioclavicular and sternoclavicular joints
While evaluating flexion and abduction note the:
Glenohumeral rhythm
___% of abduction should occur at the humerus
60%
__% of abduction should occur at the scapula
40%
Normal flexion is up to:
180 degrees
Normal range of extension is up to:
50 degrees
Normal range of abduction is up to:
180 degrees
Normal range of adduction is up to:
50 degrees
1) Place arm behind the head with elbows out
2) Have patient lower his thumb along the spine to their lowest point
3) Note what spinous process the patient can reach
External Rotation
1) Ask the patient to place the arm behind the back and reach as high as possible
2) Note the highest spinous process that can be reached with hiking the thumb
Internal Rotation
1) Anterior Deltoid
2) Have patient raise the arm forward in the sagittal plane and provide resistance
3) Pain may be suggestive of biceps tendinitis
Flexion
1) Posterior Deltoid
2) Have patient raise the arm backward in the sagittal plane and provide resistance
Extension
1) Middle Deltoid
2) Have patient raise arm to 90 degrees of abduction with the elbow flexed at 90
degrees
Abduction
What muscle?
1) Place arm in 90 degrees of abduction with slight horizontal adduction and internal rotation
2) Push down on the distal arm as the patient resists this pressure
3) Pain may be suggestive of rotator cuff tendinitis
Supraspinatus
What muscle?
1) Have patient place their hand behind the back with the palm facing away from the body
2) Have patient lift away from the back while providing resistance
3) AKA Gerber lift off
Subscapularis
1) Have patient tightly hold their humerus next to the chest
2) Attempt to abduct patients arm while they provide resistance
Adduction
1) Place the patients arm at the side in neutral rotation with elbow flexed to 90 degrees
2) Attempt to externally rotate the arm, maintain this position while applying moderate to firm pressure at the distal forearm
External rotation
1) Place the patients arms at the side in neutral rotation with elbow flexed to 90 degrees
2) Attempt to internally rotate the arm, maintain this position while applying moderate to firm pressure at the distal forearm
3) Test the strength of the Infraspinatus and Teres Minor
Internal rotation
What muscle?
1) Have patient forward flex their arms as you depress the arm with one hand and palpate the scapula with the other
2) When weak, the scapula will “wing” at the vertebral border
Serratus Anterior
1) Have the patient place both hands on the iliac crest
2) Push patients arm forward with your hand at the elbow and palpate the vertebral border of the scapula with the other hand
If functional then these muscles will lay flat against the chest wall
Rhomboid
1) Used to diagnose shoulder impingement or rotator cuff tears
2) Place one hand on the posterior aspect of the scapula to maintain in the anatomical position and use your hand to take the patients internally rotated arm by the wrist into full flexion
3) This maneuver compresses the greater tuberosity against the anterior acromion
Neer’s Impingement Sign
1) This test reinforces a positive Neer sign for impingement
2) Flex the patients shoulder to 90 degrees, flex the elbow to 90 degrees and place the forearm in neutral rotation
3) Support the elbow and then passively internally rotate the humerus
4) Pain to the subacromial space is indicative of rotator cuff tear or tendinitis
Hawkin’s Impingement Sign
1) Place patients arms in 90 degrees of abduction, 30 degrees of horizontal abduction and internal rotation with the elbow extend.
2) Push down on the distal arm as the patient resists this pressure
3) A positive sign is pain focal to the middle aspect subacromial space
Empty Can Test
1) Detects tears in the rotator cuff tear (supraspinatus)
2) Instruct patient to fully abduct their arm then ask them to slowly lower it to the side
3) If there are tears in the rotator cuff the arm will drop to the side from a position of about 90 degrees
4) If the patient is able to hold his arm in abduction, a gentle tap on the forearm will cause the arm to fall to his side.
Drop Arm Test
1) Evaluates the teres minor
2) Support patient’s arm in 90 degrees, slightly adducted, elbow flexed to 90 degrees
3) Apply resistance as patient externally rotates arm
4) Weakness indicates a positive sign
Hornblower’s Test
1) This test is helpful in diagnosing biceps tendonitis and bicep strength
3) Have patient forward flex the shoulder to 45 degrees while flexing the elbow to 90 degrees
4) Have the patient resist you as you attempt to pull their arm into shoulder and elbow extension
5) Patient will be positive for biceps tendinitis if they experience pain in the bicipital groove
Speed’s Test
1) Test subscapularis strength and possible tendon rupture
2) Instruct the patient to place the hand behind the back, palm facing away from the body
3) Apply resistance as the patient lifts away from the back
Gerber Lift-off Test
1) With patient standing or supine (for acute or chronic dislocations), place patients arm in 90 degrees abduction, with elbow flexed to 90 degrees
2) Gently externally rotate humerus to 90 degrees
3) Patients with anterior instability may be apprehensive in this position because of the sense of impending dislocation
4) Pain with apprehension is less specific
Apprehension Sign for Anterior instability
1) With patient supine, place patients arm in 90 degrees abduction, with elbow flexed to 90 degrees, and 90 degrees of external rotation
2) Apply posterior force to the anterior proximal humerus at point of external rotation when patient feels apprehensive
3) This should precent anterior subluxation
4) Test is positive if relief of pain and apprehension occurs
5) Suggests anterior glenohumeral instability
Relocation Test of Jobe
1) With patient’s arm relaxed to side place one hand on the posterior scapula and use the other hand to apply traction to the patient’s arm in an inferior direction
2) This maneuver will cause inferior subluxation of the humeral head and a widening of the sulcus between the humerus and acromion
3) A visible dimple is a positive sulcus sign
4) A positive sulcus suggest that the patient has inferior shoulder instability
Sulcus Sign
1) Place the patient’s arm in 90 degrees of flexion with maximal internal rotation with the elbow flexed at 90 degrees
2) Adduct the arm cross body in the horizontal plane while applying an axial load at the elbow to push the humerus in a posterior direction
3) If the maneuver causes a posterior subluxation or dislocation, the humeral head can be felt to clunk or jerk back into the joint as the arm is then horizontally abducted
Jerk Test
1) Flex patients shoulder to 90 degrees and then horizontally adduct the arm across the body
2) Pain over the acromioclavicular joint pathology
Cross Body or Horizontal Adduction Test
1) Place the patient’s arm in flexion 90 degrees of flexion, horizontally adduct to 20-30 degrees.
2) Have patient point thumb down, apply downward force against resistance.
3) Apply force again, but with forearm supinated.
4) Positive: Pain is worse with thumbs down, relieved with forearm supinated. Suggest labral pathology.
Obrien’s Test
Elbow angle is made by the intersection of the axes of the ____ and the ______ with the elbow extended and the forearm supinated
Humerus
Forearm
