Q

What is an important precaution when doing an axial distraction/inferior glide of the shoulder joint?

A

do not let the shoulder girdle move inferiorly, or it could impinge the brachial plexus between the clavicle and the first rib

Q

In a lateral distraction at 90 degrees of flexion, if you pull the elbow medially, this will create more of a ___ arthrokinematic action rather than a glide.

Q

Why is it important not to apply pressure with your thumbs while performing an inferior-lateral-anterior glide of the GH joint?

it will compress the neurovascular bundle

Q

What are the joint articulations of the scapulothoracic joint?

A

there are no true articulations, only muscular tissue between the scapula and the thorax!!

17
Q

What is the capsular pattern of restriction for the scapulothoracic joint?

18
Q

What is the typical ROM expected of the shoulder joint in flexion and extension, respectively?

A

flexion - 180 degrees

extension - 60 degrees

19
Q

What is the typical ROM expected of the shoulder joint in abduction and adduction, respectively?

A

abduction - 180 degrees

adduction - 45 degrees

20
Q

What is the typical ROM expected of the shoulder joint in external rotation and internal rotation, respectively?

A

ER - 90 degrees

IR - 70 degrees

21
Q

What is the typical ROM expected of the shoulder joint in horizontal adduction and horizontal abduction, respectively?

A

horiz. add - 45 degrees

horiz. abd - 100 degrees

22
Q

For the shoulder joint, which two osteokinematic motions have the same expected 180 degrees of aROM?

A

abduction and flexion

23
Q

For the shoulder joint, which two osteokinematic motions have the same expected 45 degrees of aROM?

A

horizontal adduction and adduction

24
Q

What is the expected degrees of aROM of the scapulothoracic joint in protraction, retraction, elevation, and depression?

25
What is the expected degrees of aROM of the scapulothoracic joint in medial and lateral rotation?
50 degrees
26
When using an inferior glide/shoulder depression, you should discontinue if...
there are neurological symptoms (d/t a stretching/compression of the brachial plexus)
27
Where is impingement of the brachial plexus most likely to occur?
between the 1st rib and clavicle or at the nerve roots
28
Do NOT perform distraction of the scapula IF...
the patient has a winging scapula or paralysis of the long thoracic nerve
29
What could the therapist do when performing scapulothoracic mobilizations that would make them ineffective?
use too much pressure/too heavy or intense of touch that will cause discomfort + muscle guarding
30
Compressions to subscapularis should be discontinued IF...
the technique produces pain or there is a lot of crepitus
31
Lateral distraction @ 90 degrees of flexion and axial posterior glide can both be used to increase what osteokinematic motion?
horizontal adduction
