1

peripheral relay info to and from the

CNS

2

peripheral nerves include

sensory and motor (ANS)

3

symptoms of peripheral neuropathy

numbess/tingling/prickling (paresthesis)
pain (allodynia)
may affect internal organs (ANS)
may lead to paralysis, muscle wasting, organ failure

4

mononeuroapthy

damage to one peripheral nerve (median in CTS)

5

polyneuropathy

multiple peripheral nerves throughout body

6

examples of polyneuropathy

guilian-barre syndrome, diabetes neuropathy, charcot-marie tooth disease

7

what parts of nerve may be damaged

axonal or myelin sheeth damage

8

what types of nerves may be damaged

motor
sensory
autonomic

9

these neuropathies are caused by?

physical injury/trauma
(repetitive stress, cumulative damage from repetitive use/compression injury or entrapment)

disease or disorders
(metabolic/endocrine or autoimmune.....)

10

ulnar nerve compression due to repetitive activity overuse is found in what canal

Guyon's canal

11

what medications cause peripheral neuropathy?

AIDS antiviral drug didanosine
antibiotics
gold compounds
chemotherapy drugs

12

carpal tunnel syndrome due to

compression of median enrve cause of swelling in tissue in carpal tunnel

13

sensations of median nerve compression/entrapment (which fingers)

tingling/numbness of thumb, index, and middle fingers

14

median nerve is formed by what roots of BP

C5-C7 lateral cord of BP
C8-T1 median cord of BP

15

median nerve innervation

2LOAF

1st and 2nd lumbrical
opponens pollicis
abductor pollicis BREVIS
flexor pollicis BREVIS

16

conditions that may lead to carpal tunnel

obesity
pregnancy
diabetes
arthritis
hypothyrodism
trauma
repetitive work or task (cummulative trauma)

17

transverse carpel ligament release is for

carpal tunnel (median nerve)

18

CTS diagnosis

- examine neck, shoulder, elbow, pulses, and reflexes
- To exclude other conditions that can mimic carpal tunnel syndrome
- To identify compression

􏰀 Wrist physical exam
◦ For swelling, warmth, tenderness, deformity, and discoloration

􏰀 Phalen’s test & Tinel’s sign
􏰀 Nerve Conduction Velocity & Electromyography

19

CTS symptoms

numbness "pins and needles in fingers"
pain that is worse at night (interupts sleep)
burning or tingling of thumb, index, and middle fingers or pain that moves up arm and elbow
hand weakness, difficulty gripping objects with hands, or dropping objects
difficulty manipualting small objects
swollen feeling in fingers

20

cubital tunnel syndrome has what symptoms

numbness and tingling along ulnar nerve

21

what is weak in cubital tunnel syndrome

weak grip

22

most common site of ulnar nerve compression

elbow (cubital tunnel syndrome)

23

ulnar innervation

forearm
flexor carpi ulnaris
flexor digi profundus (ulnar part)

thenar
adductor pollicis
flexor pollicis brevis (deep head)

fingers
palmar and dorsal interossei
3rd and 4th lumbricals

hypothenar muscles
abductor digi minimi
opponens digiti minimi
flexor digiti minimi

24

most common compressive neuropathy

carpal tunnel syndrome

25

2nd most common compressive neuropathy

cubitial tunnel syndrome

26

cubital tunnel syndrome affects what gender more

men

27

cubital tunnel may causes what deformity

ulnar claw hand deformity

28

cubital tunnel syndrome may be casued by

- constricting fascial bands
◦ subluxation of the ulnar nerve over the medial epicondyle
◦ cubitus valgus
◦ hypertrophied synovium
◦ tumors, ganglia
◦ direct compression
◦ repeated resting elbow on hard surface

29

Work may aggravate cubital tunnel syndrome secondary

to repetitive elbow flexion and extension

30

occupational implications for neuropathies

upper/lower extremity + hands
