List all bones involved in shoulder movement
scapula, ribs, clavicle, humerus, sternum
GH joint is what joint type
ball and socket
motions involved at GH joint
flex, extend, rotation, ab, add
AC joint is mainly for
stability
AC joint is what joint type
synovial gliding
SC joint is what joint type
saddle
ST joint is what joint type
plane or synovial gliding
motions of ST joint
elevation and depression, protraction and retraction, UR and DR
xipho-sternal and costo-chondral are what joint types
cartilage
Coracoacriomial joint is what type
fibrous, or ligamentous
CA joint is mainly for
stability
SC joint motions
allows for protraction and retraction, UR, DR, allows for some side motion too (he says elevation and depression are same as UR and DR
muscles involved in shoulder motion are divided into 3 areas
- Muscles that connect the axial skeleton (ribs and vertebrae as o) with the scapula (as insertion)
- Muscles that connect the skeleton and the humerus (as insertion)
- Muscles that connect scapula and humerus (as insertion)
main job of the muscles that connect the axial skeleton with the scapula
(main job of these is to move the scapula: protraction, retraction, elevation depression, UR, DR)
as a whole (all parts of) the trapezius does what motion
UR scapula
Upper traps motion
elevate and UR scapula
mid traps motion
retract scapula and UR scapula (adduction same as retraction)
lower traps motion
depress and UR scapula
nerve of trapezius
spinal accessory nerve XI
levator scapulae motion
elevates scapula
nerve to levator scapulae
dorsal scapular nerve
primary protractor of scapula
serratus anterior
the force couple that produces upward rotation exists bc of what two muscles
serratus anterior and trapezius
Main UR due to the force coupling action
serratus anterior and trapezius
nerve to serratus anterior
long thoracic nerve

lats
motion of lats
Adduction shoulder, extension shoulder, IR shoulder, depress scapula
nerve to lats
thoracodorsal nerve
this muscle creates the anterior portion of the axillary fold
pec major
actions of pec major
flexion, add, medial rotation (primary motion is to horizontal adduct-this happens both in the shoulder and the scapula) this is the primary horizontal adductor
primary horizontal adductor of shoulder

anterior delt action
flexes shoulder
middle delt is the primary___ of shoulder
abductor
primary flexor of shoulder
anterior delt
posterior delt is the primary ___ of shoulder
extensor
nerve to deltoids
axillary
actions of coracobrachialis
flexes and adducts shoulder (no scapula mvmt)

musculocutaneous nerve
action of long head of biceps
main action is to flex elbow, for the shoulder it mainly stabilize the shoulder and strengthen the ant capsule, assist in flexion of shoulder (but minimally)
nerve to biceps brachi
musculocutaneous
actions of long head of triceps
main action is to extend elbow, for the shoulder it mainly stabilizes the shoulder and strengthen the post capsule, assists is shoulder ext but minimally
nerve to triceps
radial nerve
when palpating, how to find the coracoid process
find where AC joint and go down ½ inch and in ½ inch
which vertebrae (spinous process) is most prominent when head is flexed
C7 most prominent when head isn’t flexed, when head is flexed T1 is most prom
what vertebrae (spinous process) can be found by drawing a line between the inferior angles of the scapula

Testing ROM for upper trap, levator scap basics
prone, use one had on scapula to guide and one hand on bicepital area to move into scapular elevation
when doing MMT, you always do what first
PROM, then AROM
explain diff between ROM and MMT in regards to positioning the pt for testing elevation of scapula
elevation of scapula is upper traps and levator scap: for ROM they are prone and you place one hand on biceps to elevate the scap and one hand on scap itself to guide, for MMT they are seated in chair
Where do you palpate for testing elevation of scapula
lateral to cervical spinous processes
gravity eliminated for MMT testing upper traps and levator scap (position of pt)
prone
In gravity lessened, if pt can perform the motion fully it is a grade
2
in gravity lessened, if pt can perform the motion partially it is a grade
2 -
in gravity lessened, if pt cannot perform the motion but you feel the muscle contract it is grade
1
main motion of middle trap
adduction scapula
again, scapula adduction is aka
retraction (middle trap) scapula
position to test ROM and MMT middle trap
prone, 90/90, palm down, as they lift their arm straight up from the table
Where do you stand when MMT middle trap
opp side of arm you are testing
GL position for middle trap (for pt)
seated, arm on table (with cloth under), arm bent at 90, knuckles forward
muscle that does depression and adduction of scapula
lower trap
Describe position and motion of testing the lower trap
prone, superman arm as they protract up and retract down
where to apply resistance when testing lower trap
lateral aspect of scapula
where do you stand when MMT lower trap
opp side of arm testing
2 muscles that don’t really have a GL position (they are modified positions so GL is same as regular)
lower trap and coracobrachialis
Where do you palpate with lower trap
btwn the lower scapular spine and the spinous process of vertebrae
Rhomboids do what motions
adduction and DR
what position should you think of when testing rhomboids
prone handcuff
again, lower trap does what
depress and adduct
GL position for testing rhomboids
they are seated doing same motion as the regular
when testing rhomboids (MMT) your resisting hand is doing what motion, your stabalizing hand is where
as you resist, with your hand on the vert border, you do a scoop motion, stabalizing hand is on opp side of thorax
How much resistance do you apply with any GL position
NONE, never apply resistance with GL
Serr Ant motion
protraction and UR
nerve to Serr ant
long thoracic nerve
what position should you think of when you test the serr ant
supine, ceiling punches
where to palpate serr ant
around ribs 8-9 close to lateral scapula
GL position for Serr ant
they are seated facing table with arm straight out on table as they protract
break time
ok
to test shoulder flexion ROM, where do you stabalize during movement
almost making a “c” at top of shoulder, stabalize at clavicle
boney landmarks for shoulder flexion and ext
thorax, acromion and lat epicondyle
axis landmark for shoulder flexion and ext
acromion
stationary landmark for shoulder flexion and ext
midline of trunk
movable landmark for shoulder flexion and ext
lat epicondyle
shoulder ext goni measurement, pt is
prone
when doing goni for shoulder flexion, remember that pt thumb should be pointed
up
when you think of hor. adduction, what muscle should you think of
pec major
boney landmarks for measuring shoulder ab and add
acromion, parallel to sternum, medial epicondyle
When measuring goni for abd of shoulder, pt should be
side lying, watch for rotation
measuring goni for shoulder adduction, pt is
supine
explain basics for measuring goni for IR and ER of shoulder
pt is supine with arm at 90/90, place towel under elbow, position goni with arms straight up and down (both perp to floor)
normal ER of shoulder
0-90
normal IR of shoulder
0-70
boney landmarks for shoulder ER and IR
olecranon, perp to floor, ulnar styloid process
With goni measurments for shoulder adduction, what must you do before you begin to actually adduct the limb
raise arm up approx 50 degrees (clear it) to get proper adduction
when doing goni for shoulder adduction, the stationary arm (that is parallel with the sternum) goes
outside of the arm, not inside.
lollipop goni position (sorry Michelle this makes sense in my head :)
shoulder flexion and extension, GH adduction and abduction
For hor abd and add goni, how is goni placed
zero it out first with the goni all in a straight line (then line the axis with the acromion, stationary towards C7 and movable with lateral epicondyle) after they hor add
explain motion of arm when testing coracobrachialis
supinated and externally rotated as the shoulder flexes
for shoulder extension, where do you palpate during AROM
post axillary fold
what 3 muscles are you testing in shoulder extension
post delt, lats, teres major
When testing abduction, what 2 muscles are you testing (one is the main one, other is accessory abductor)
main one- mid delts, accessory-supraspinatus
What muscle are you testing with hor. abduction
post delt
differences btwn pt position in testing ROM vs MMT with hor abduction and adduction
ROM - pt is seated, MMT - pt is prone for hor abd and supine for hor add
the 2 muscles you are testing when you perform shoulder ER
teres minor, infraspinatus
