33. Which of the following joints of the hand would have the greatest ROM about a medial/lateral axis of rotation (from the anatomical position)

6. Manuel is a 42 year old male construction worker with a history of right shoulder pain. During your examination, you observed he had decreased scapulothoracic upward rotation when he raised his arm in the scapular plane. According to expected coupling between the SC, AC and scapulothoracic motions, which sternoclavicular and acromioclavicular motions may also be most related with decreased scapulothoracic upward rotation?

38. The extensor expansion and unique connective tissue structures of the fingers

1. The shoulder joint complex

15. The serratus anterior acting at the AC joint

34. Muscle function of the wrist and hand

10. EMG records show the rhomboids are active in elevation of the arm, despite their anatomical description as downward rotators of the scapula. Which of the following seems most consistent with biomechanical principles:

30. During pronation motion from an initial anatomical position

19. Contraction of the infraspinatus, as depicted in the diagram below regarding action on the scapula about an AC joint axis of rotation:

27. Elbow motion during daily functional activities (opening doors with doorknobs, combing hair, eating, etc.)
