What special orthopedic test involves an assessment of ROM using two maneuvers in which physician observes how far the patient can reach?

Answer 27

Apley Scratch test

Question 28

Describe the apprehension test of the shoulder including structure being assessed, positive test, and indication

Answer 28

Apprehension tests for glenohumeral instability Patient is seated or supine. Shoulder is abducted to 90 and elbow flexed to 90. Stabilize shoulder with one hand (blocking linkage) and force arm into external rotation with other hand + test = patient apprehensive of repeat dislocation --> indicates glenohumeral instability

Question 29

Describe the sulcus sign of the shoulder including structure being assessed, positive test, and indication

Answer 29

Sulcus sign = assessing glenohumeral instability Grasp patient's elbow and apply inferior traction + test = indention appears in area beneath the acromion --> indicates glenohumeral instability

Question 30

Describe the Yergason's test including structure being assessed, positive test, and indication

Answer 30

Yergason's = assesses long head of the bicep Patient's arm at side with elbow flexed at 90. Examiner uses one hand to palpate bicipital groove and monitors there, while other hand grasps patient's wrist. Have patient supinate and externally rotate against resistance + test = pain and/or tendon subluxation out of groove --> indicates unstable bicipital tendon/subluxation bicipital tendonitis

Question 31

Describe the Speed's test including structure being assessed, positive test, and indication

Answer 31

Speed's test = assesses long head of biceps Patient's arm forward flexed (50-90) at the shoulder with hand supinated. Slightly flex patient's elbow. Resist at forearm while patient forward flexes shoulder (resistance to cephalad/superior motion) + test = pain in bicipital groove --> indicates bicipital tendonitis of longhead biceps

Question 32

Describe the Empty Can Test including structure being assessed, positive test, and indication

Answer 32

Empty can test = assesses supraspinatus m. of rotator cuff Flex patients shoulders/arms to 90 while horizontally abducting approximately to 45 degrees. Then internally rotate both arms so thumbs are pointing down. Press down on forearms while patient resists. + tests = pain or weakness --> indicates rotator cuff pathology (specifically supraspinatus)

Question 33

Describe the Drop-Arm Test including structure being assessed, positive test, and indication

Answer 33

Drop-Arm test = assesses supraspinatus m. of rotator cuff Patient abducts arm to 90; then slowly drop arm + test = arm will drop or gentle tap on wrist will cause arm to drop --> indicates full thickness tear of supraspinatus m.

Question 34

Describe the Neer Impingement test including structure being assessed, positive test, and indication

Answer 34

Neer Impingement = assesses rotator cuff impingement Stabilize patient's shoulder, forearm is pronated. Passively flex shoulder to fully flexed position + test = pain --> indicates subacromial bursa or rotator cuff impingement

Question 35

Describe the Hawkins test including structure being assessed, positive test, and indication

Answer 35

Hawkins = tests for rotator cuff impingement Flex shoulder to 90, flex elbow to 90 and passively rotate the humerus into internal rotation. This opposes rotator cuff against coracoacromial ligament and acromion + test = pain --> indicates rotator cuff or subacromial bursa impingement

Question 36

Describe the lift-off test including structure being assessed, positive test, and indication

Answer 36

Lift off = tests subscapularis m. Place patient's arm into internal rotation and extension. Patient pushes arm into further internal rotation as doctor resists + test = weakness (inability to resist) --> indicates subscapularis weakness

Question 37

Describe upper Apley Scratch test

Answer 37

Patient abducts arm placing palm of hand behind their neck with palm facing toward the body. Patient should attempt to scratch the lowest possible vertebrae (coupled external rotation and abduction)

Question 38

Describe Lower Apley Scratch test

Answer 38

Patient places arm behind their back with palm facing outward and dorsum of hand resting on their mid-back. Patient should attempt to scratch highest possible vertebrae (coupled internal rotation and adduction)
