19
Q

What is the ROM of shoulder flexion and abduction?

A

180°
(GH-120°)
(Scapulothroacic-60°)

20
Q

What is the primary muscle activity for shoulder flexion and abduction?

A

Rotator cuff deltoid force couple

Scapulothoracic force couple

21
Q

What do the rotator cuff muscles do to the humeral head?

A

Hold it in the glenoid fossa and pull inferiorly

22
Q

What nerve innervates the levator scapulae and rhomboids?

A

Dorsal scapular nerve

23
Q

What is the action of the levator scapulae and rhomboids on the scapula?

A

Downward rotation

24
Q

What nerve innervates the serratus anterior?

A

Long thoracic nerve

25
Q

What is the action of the upper trap, lower trap, and serratus anterior?

A

Raises the arm (shoulder abduction)

26
Q

What is a primary impingement?

A

Due to anatomy (hooked acromion)

27
Q

What is a secondary impingement injury?

A

Weakness of rotator cuff

Scapula position

28
Q

What movement must occur in the scapula to avoid pinching under the acromion?

A

Upward rotation

29
Q

Why does a rotator cuff tear lead to an impingement?

A

Humerus head is not being pulled down and has increased superior glide

30

33
Q

What is the freezing stage?

A

Severely restricted ROM and pain at 3-9 months

34
Q

What is the frozen stage?

A

Severe stiffness and minimal pain at 9-15 months

35
Q

What is the thawing stage?

A

Improving ROM and minimal pain

36
Q

How does the clavicle glide on the sternum during scapular elevation?

A

Inferiorly

37
Q

A patient has OA and degeneration on their ACJ which causes pain to occur with compressive loads, which position would most likely provoke these symptoms?

A

90° abduction

38
Q

What is affected when someone gets a + sulcus sign (limits inferior translation)?

A

Superior GH ligament

39
Q

What is the best treatment option for someone with adhesive capsulitis?

A

Corticosteroid injection combined with PT

40
Q

What are some tests used to assess shoulder pain?

A

SPADI and DASH (higher score=higher disability)
