Question 6

What do you look for on inspection?

Answer 6

Asymmetry
Deformity– separation or dislocation
Atrophy
Signs of trauma (swelling, ecchymosis)

Question 7

What do you assess for ROM?

Answer 7

Forward flexion
Abduction (supraspinatus)
External rotation (infraspinatus and teres minor)
Internal rotation (put hands behind back, subscapularis)

Question 8

What do you assess for strength testing?

Answer 8

Abduction -- deltoid, supraspinatus
External rotation-- infraspinatus, teres minor
Internal rotation -- subscapularis
Flexion-- biceps
Extension -- triceps, C7
"Empty can" -- supraspinatus
"Lift off test" -- subscapularis
