MOI and etiology for shoulder

impingement MOI

is typically caused by repetitive overhead activities, resulting in compression of the rotator cuff tendons in the subacromial space.

chronic

Primary or secondary impingement

RTC tendinopathy MOI

Chronic onset

Muscle imbalance, scapular stabilization, capsular laxity, impingement, hooked acromion

rtc tendinopathy S/S

early complaint(deep pain after activity)

-radiation pain

-clicking

-painful arc

impingement S/S

pain during overhead movement

-painful arc

-relief when inferior glide applied OH ABD

atrophy of infraspinatus/supraspinatus

-radiating pain

-popping, clicking possible

SLAP lesion MOI

Acute or chronic

-instability, impingement, or excessive force in external rotation/abduction

SLAP lesion S/S

Pain in superior shoulder

Forward shoulder

Scapular dyskinesis

Chronic/overuse

Scapular dyskinesis S/S

Loss of strength/power/endurance

Dominant may be lower and more protracted at rest

GIRD

S/C joint sprains MOI

FOOSH- longitudinal force on the clavicle or traction forces

S/S joint sprains s/s

pain with protraction, retraction and joint play

• neck tilted to side of pain

A/C joint pathology MOI

FOOSH, blow to superior acromion process

A/C joint pathology S/S

pain over the A/C joint

-pain with overhead motions

-step off deformity

cervical radiculopathy MOI

Disc herniation

osteophyte formation

cervical radiculopathy S/S

Cervical pain, may or may not be radiating into trapezius, scapula, shoulder, arm, wrist, hand

Paresthesia along distribution of involved nerve root

Disc pathology MOI

Disc degeneration

disc pathology S/S

Joint pain

cervical stiffness

AROM and PROMmay be limited due to pain and stiffness

facet joint dysfunction MOI

Acute trauma- whiplash or repetitive motion

facet joint dysfunction s/s

posterior neck pain and pain during extension and rotation

Clicking or catching

-localized pain, lateral to spinous process

brachial plexus pathology MOI

Traction or impingement

brachial plexus S/S

pain in traps and deltoid, radiating into the arm

Paresthesia along distribution of the involved nerve

TOS MOI

Pressure on the trunks and medial cord of brachial plexus, subclavian artery, or subclavian vein
