1
Q

neuropraxia

A

segmental demyelination
transient disruption
fast recovery w good prognosis

2
Q

axonotmesis

A

loss of axon continuity
prolonged disruption
longer recovery w fair prognosis

3
Q

neurotmesis

A

completely severed

recovery w surgery w variable prognosis

4
Q

pathology of peripheral nerve injury

A

compression
traction
avulsion
laceration

5
Q

S/S peripheral nerve injury

A
altered/absent sensation in nerve distribution 
decreased strength of innervated mm
diminished reflex
sympathetic changes
special tests
6
Q

lateral cutaneous nerve
segments
motor or sensory

A

L2/3

sensory lateral thigh
tight jeans

7
Q

obturator nerve segments

motor or sensory

A

L2-4

motor: adductors
sensory: skin of medial thigh

8
Q

femoral nerve
segments
motor or sensory

A

L2-4
motor: anterior thigh, hip flexors and knee extensors

sensory: skin covering these mm

9
Q

sciatic nerve
segments
motor or sensory

A

L4-S3
motor: mm of posterior thigh

sensory: none but indirectly skin of lateral leg, heal and foot

10
Q

Whats two things that comes off the sciatic nerve

A

tibial nerve and common peroneal nerve

11
Q

what effects common peroneal nerve

A

tight cast, so you’ll see a foot drop

12
Q

acute nerve injury treatment

A

immobilize / unnload
splint/brace/tape
movement
education

13
Q

recovery phase of nerve injury

A

motor training
desensitization
discriminative sensory re education

14
Q

chronic phase of nerve injury management

A

compensatory function

preventive care

15
Q

types of TOS

A
arterial 
venous
traumatic neurovascular
true neurogenic
disputed TOS
16
Q

key impingement areas in TOS

A

Scalene triangle
costoclavicular space
axillary interval

17
Q

Etiology of TOS

A

congenital abnormalities

Trauma

18
Q

vascular TOS arterial pathology

A

compression of subclavian

19
Q

vascular TOS arterial ethology

A

bony anomaly (ie. cervical rib)

20
Q

vascular TOS arterial S/S

A
chronic UE ischemia 
pain w effort
cool to touch
decreased cap refill 
decreased pulse
tissue necrosis
21
Q

vascular TOS venous patho

A

venous thrombosis involving subclavian axillary veins

22
Q

When does vascular TOS venous happen

A

sudden onset young healthy person after UE exertion

23
Q

acute occlusion

A

diffuse UE swelling
cyanosis
pain

24
Q

chronic thrombosis

A

venous collateral formation

dilated veins in neck chest shoulder

25
Q

True neurological TOS high or lower plexus

A

lower (c8-t1 nerve roots to lower trunk)

26
Q

S/S true neurological TOS

A

C8-t1 motor /sensory changes

hand wasting

27
Q

when does traumatic neuromuscular TOS happen

A

clavicle fracture

28
Q

Disputed or Symptomatic TOS

A

compression or traction of brachial plexus

29
Q

Disputed or Symptomatic TOS results in

A

scalene mm fibrosis
scar tissue
mm imbalance

30
Q

lower plexus disputed TOS type

A

pain in neck or supraclavicular region along medial UE

31
Q

upper plexus type TOS

A

pain in shoulder radiates to neck, thorax

32
Q

symptomatic TOS clinical presentation

A

decreased scap mm control, strength n substation recruitment

33
Q

conservative treatment TOS

A
decrease compression 
increase extensibility of tight tissue
mobilize restricted joints
strengthen 
posture education 
breathing education
34
Q

how are arterial, venous true and neurogenic and traumatic TOS treated

A

surgical

35
Q

injury to a nerve root vs peripheral nerve

A

nerve root - radiculopathy

peripheral - periperhal neuropathy
