26
Q

what muscle(s) are primarily tested during shoulder horizontal adduction MMT?

A

pectoralis major

27
Q

for grades 3 and up, how should the pt be positioned during shoulder horizontal ADD MMT?

A
  1. supine
  2. arm pointed towards the ceiling
  3. sligh elbow flexion

“bring your arm towards the middle, don’t let me pull it back out”

28
Q

how can you isolate the clavicular head of the pectoralis major during shoulder horizontal ADD MMT?

A

begin with the shoulder at 600 of ABD and tell the pt to move arm “up and in”

29
Q

how can you isolate the sternal head of the pectoralis major during shoulder horizontal ADD MMT?

A

begin with the shoulder in 1200 of ABD and tell the pt to move arm “down and in”

30
Q

where is resistance applied when performing a horizontal shoulder ADD MMT?

A

distal humerus/elbow

pull towards the therapist

31
Q

what muscle(s) are primarily tested when performing shoulder ER MMT?

A
  1. Infraspinatus
  2. Teres Minor
32
Q

for grades 3 and up how is the pt positioned during shoulder ER MMT?

A
  1. prone, head turned towards testing side
  2. hand hangin off side of table
  3. PT supports under the arm
  4. instruct pt to move forearm up and towards the ceiling and hold there
33
Q

for grades 0,1,2 how is the pt positioned during shouder ER MMT?

A

Can do gravity minimized on table (towel under to reduce friction)

or

pt laying prone with arm off the table (instruct them to turn their palm out clockwise)

34
Q

where do you stabilize when performing shoulder ER MMT?

A

distal humerus for support

35
Q

where is resistance applied during shoulder ER MMT?

A
  1. pectoralis major
  2. latissimus dorsi
  3. anterior deltoid
38
Q

for grades 3 and up, how is the pt positioned during shoulder IR MMT?

A
  1. prone
  2. head facing towards testing side
  3. start with hand hanging down and PT supporting arm
  4. instruct pt to move forearm backwards and hold there
39
Q

for grades 0,1,2 how is the pt positioned during shoulder IR MMT?

A

Gravity minimized = seated w/towel under arm

OR

laying prone with arm handing entirely off the table, instruct pt to turn their arm counter-clockwise

40

for grade 3 and up, how should the pt be positioned during elbow flexion MMT?

A
  1. sitting
  2. elbow flexed past 900
  3. for isolation:
    • biceps = palm up (supinated)
