Scapular Dyskinesis Type I

inferior angle dysfunction — angle more prominent due to anterior tilting —> correlated with subacromial impingement or RC dysfunction

Scapular Dyskinesis Type II

medial border dysfunction — border prominance —> due to IR of scap secondary to weak rhomboids and serratus

Scapular Dyskinesis Type III

excessive elevation of superior border vs upward rotation of scap —> RC pathology or adhesive capsulitis

GIRD

glenohumeral internal rotation deficit —> lack of GH IR

GIRD degree loss

>20 degree of dominate side IR OR >5 degree loss total arc of motion on dominate side

GIRD causes

1. humeral retroversion

2. post GH jt capsule tightness

3. post RC muscle tightness/stiffness (IS and TM)

4. acute post RC muscle stiffness (IS and TM)

glenohumeral retroversion (HRV)

bony torsion (twist) in shaft of humerus — HH turned posterior on glenoid

throwing exposure does what to de-rotation

slows

if there is an increase in HRV, what happens to ER and IR

ER has more ROM and IR has less ROM

A loss in IR for HRV means what for ER

gain in ER — bony issue only

Total arc of motion is what

IR ROM + ER ROM (both supine)

if total arc is = dom vs non dom

anatomic GIRD (DO NOT TREAT)

if dominate shld total arc is < 5 degree

pathological GIRD (can treat)

Is posterior RC tightness/stiff is a greater factor than posterior capsule tightness in pathologic gird?

YES

What is frozen shoulder

inflammation of shoulder from subacromial pain syndrome, small tear, or other trauma

Why do people not move their shoulder with frozen shoulder?

Because of pain

Frozen shoulder capsule becomes…

thickened and fibrotic — fixed to humeral head = capsular stiffness

frozen shoulder capsular pattern

ER > ABD > IR (most common)

ER > FLEX > IR

EER > Elevation > IR

primary frozen shoulder (idiopathic)

no known cause

insidious onset

40-65 y.o

F>M

diabetes or thyroid history

obesity

resolves in 15-24 months

Risk factors for idiopathic frozen shoulder

prolonged immobilization

prolonged disuse

myocardial infarction

autoimmune disease

secondary frozen shoulder

AC that “sees you”

secondary to trauma

faster prognosis

smaller capsular pattern

50% loss

capsular pattern is based on what?

% loss of ER > Flex/ABD > IR

frozen shoulder exam pearls

spend time with ROM —> can be false positives

how many stages are there in frozen shoulder

4 stages

Stage 1 frozen shoulder

inflammation in shld

painful loss of ROM - no PROM

“pre-adhesive” stage

Stage 2 of frozen shoulder

“freezing” or pain stage

pain with AROM and PROM (more than AROM) with empty feel (7/8-10)

synovium red and angry

3-9 months

Stage 3 frozen shoulder

“frozen” stage

very little synovitis

loss of motion/impaired function

PROM = AROM

pain @ end range with firm end feel (4-6)

4-12 months

Stage 4 frozen shoulder

“thawing” stage

very little pain (0-3)

AROM = PROM

significant stiffness, firm end feel

no synovial reaction

gradual return to motion

muscle weakness

12-24+ months

CPG (A level evidence)

corticosteroid injection (CSI)

pain and muscle guarding as primary limit to motion

immediate improvements in pain and ROM after injection

use in FREEZING phase

CPG (B level evidence)

patient education on natural courses of disease

modify activities

match intensity of stretching protocol to irritability

do stretching exercises (diff in diff stages)

Freezing stage intervention

*caution — irritable tissue will stiffen further

low grade joint mobs

maintain, don’t gain

scap mobs, soft tissue norm

modify activities: open pack position

pendulum exercises

pain relieving modalities

frozen stage intervention

LLLD

— 5” for 24x up to 30” for 4x

aggressive capsular stretching

PT 1x week for 2-3 weeks

daily exercises

thawing stage intervention

aggressive stretching

LLD stretching

strength more important for AROM-PROM differences

daily stretching

strength 3x week

CPG (c level evidence)

modalities (estem, diathermy) to augment stretching

joint mobs

manipuation under anesthesia

discharge criteria for frozen shoulder

pt is out of frozen stage

independent HEP

no improvements with manual interventions

elbow traumatic injuries

MVA

collision/impact

FOOSH (fall out on stretched hand)

post elbow injury consideration

overly aggressive stretch/mobs/manipulation to elbow

anterior capsule of elbow is very thin

brachialis passes over capsule = bleeding from trauma cause capsular scarring

bleeding can lead to fibroplasia, calcification, myositis ossificans

outcomes of elbow injury

pain

ROM (elbow, forearm)

strength (elbow, grip)

functional ADL’s

elbow injury intervention

modalities as indicated

PROM, AROM, stretching (don’t be too aggressive)

joint mobs/manipulation (when safe)

dynamic splinting

strengthening (once ROM improved and trauma healed more)

instability is?

state of being unstable, lack of stability or firmness

behave in unpredictable, changeable, or erratic matter

laxity is?

state or quality of being loose

laxity in shoulder

one’s genetic predisposition of tissue elasticity

no pain

common: high beighton index

rare: marfan’s syndrome

instability in shoulder

painful hypermobility

causees for instability in shoulder

born loose: poor dynamic stability in genetic laxity
