what muscles are considered the prime movers of the shoulder?
pectoralis major, latissimuss dorsi, teres major, deltoid (LH of biceps, triceps)
what muscles are considered the scapular stabilizers?
serratus anterior, latissimus dorsi, trapezius, rhomboids, levator scapulae, pectoralis minor
what is the scapulohumeral rhythm?
2:1 ratio of glenohumeral motion to scapulothoracic motion
what are the force couples of the shoulder?
deltoid-rotator cuff
upper trap-serratus anterior
what are you looking for when looking at joint motion?
quality, quantity, provocation, where in range symptoms produced
scapulo-humeral rhythm: anterior and posterior
what functional motions should be looked at in a shoulder evaluation?
hand behind head: combined abd/ER
hand behind back: combined ext, add, IR
what are the SA pain tests?
neer’s: shoulder flexion with arm in IR+ over pressure
hawkins-kennedy: 90 degrees flexion with IR
what makes up the rotator cuff?
supraspinatus, infraspinatus, teres minor, subscapularis
what are the ACJ provocation tests?
cross body adduction
resisted horizontal ext/abd
what tests are for the biceps tendon and ACJ/labrum?
speeds test: long head of the biceps/bicipital tendonitis
active compression test: ACJ/labral pathology
what are the common locations of tenderness in the shoulder?
subacromial space, supraspin tendon, greater tuberosity, bicipital groove, ACJ line, upper trap and levator scap
what does the wall push up test?
serratus anterior weakness
a (+) test = scapular winging
what are the scapular alleviation tests?
scapular assistance test
scapular repositioning test
what degree of FROM is needed for combing hair, perineal care, washing the contralateral UE, and overhead shelf?
combing: abd 105-120, ER 90, add 30-70
perineal: abd 30-45, IR 90+, abd 75-90
washing: flex 60-90, IR 90, add 60-120
overhead: flex 70-80, ER 45, add 70-80
what are some contributing factors to internal rotation loss?
bony adaptation, scapular posture, posterior musculotendinous tightness, shoulder fatigue, posterior capsular tightness (anterior pseudolaxity, superior and anterior/posterior migration
what is the kibler classification or scapular posture?
type 1: prominent inferior angle - RTC tendinopathy
type 2: prominent medial border - GH instability
type 3: superior migration of medial border - RTC weakness
what is thrower’s sick scapula?
Scapular malposition
Inferior medial border prominence
Coracoid pain and malposition
dysKinesis: labral (inferior/medial border), rotator cuff (superomedial border)
what does spinal accessory nerve palsy present as in relation to scapular posture?
upper trap atrophy and scapular depression
(+) flip sign
no medial winging with flexion or abd
what does long thoracic nerve palsy present as in relation to scapular posture?
medial winging with active flexion
