Shoulder and Elbow MMT Flashcards
what muscle is primarily tested in shoulder flexion?
anterior deltoid
what secondary muscles contribute to shoulder flexion?
- coracobrachialis
- supraspinatus
- biceps brachii
- trapezius (shoulder hiking)
- pectoralis major (if there is horizontal add)
for grades 3 and up, how should a pt be positioned when tested shoulder flexion?
- short sitting
- arm flexed to 900
for grades 0,1,2 how should a pt be positioned to test shoulder flexion?
- side lying
- palpate for anterior deltoid
where do you stabilize when testing shoulder flexion (MMT)?
stabilize at shoulder
where is resistance applied when performing shoulder flexion MMT?
distal humerus, downward direction
what are some common substitutions pts may utilize during a shoulder flexion MMT?
- ER of arm
- shoulder hiking
- leaning trunk backwards
what muscle(s) are primarily tested during shoulder extension MMT?
- posterior deltoid
- latissimus dosi
- teres major
what secondary muscles contribute to shoulder extension?
long head of triceps brachii
for grades 3 and up, how should a pt be positioned during shoulder extension MMT?
- prone
- face turned towards testing side
- palm facing up
- elbow remains extended and straight
for grades 0,1,2 how should a pt be positioned for shoulder extension MMT?
- side lying
- palpate for posterior deltoid or teres major
where do you stabilize when testing shoulder extension?
at the shoulder
where is resistance applied when performing shoulder extension MMT?
distal humerus
what muscle(s) are primarily tested during shoulder abduction MMT?
- middle deltoid
- supraspinatus
for grades 3 and up how should a pt be positioned when performing shoulder abduction MMT?
- short sitting
- shoulder abducted 900
for grades 0,1,2 how should a pt be positioned when performing shoulder abduction MMT?
- supine
- towel under arm to reduce friction on bed
where should the tester stabilize when performing shoulder abduction MMT?
at the shoulder
where is resistance applied when performing shoulder abduction MMT?
distal humerus
what are some common substitutions that may occur when performing shoulder abduction MMT?
- trunk lateral flexion
- scapular/shoulder elevation
- using biceps brachii (arm will ER)
what muscle(s) are primarily tested during shoulder horizontal abduction MMT?
- posterior deltoid
for grades 3 and up how should the pt be positioned when peforming shoulder horizontal abduction MMT?
- prone facing arm being tested
- thumb down
- elbow at 900 (only for grade 3)
“lift your elbow to the ceiling, don’t let me push you down”
for grades 0,1,2 how should the pt be positioned when performing horizontal shoulder abduction MMT?
- sitting
- arm supported on surface
“slide your arm backwards on the table”
