Review of UMN and LMN Flashcards
Peripheral nerve injury
can be a damage at the nerve root level or to the peripheral nerve itself
Injury to the medial nerve - carpel tunnel syndrome clinical presentation
- Atrophy muscle
- weakness or paralysis
- pain along the nerve distribution
- numbness along the nerve
- sensory loss
- Over time loss of ROM
Injury to the medial nerve - carpel tunnel syndrome muscles involved
flexor pollicis brevis and longus, abductor pollicis brevis, and muscles distal to site of injury
Injury to the nerve root C6 Radiculopathy clinical presentation
- numbness and tingling following nervous system distribution
- pain
- sensory loss
- weakness
- decreased DTR
- hyporeflexia
injury to the nerve root C6 muscles involved
myotomal C6
Biceps
Brachioradialis
Wrist extensors : ECR
Radiculopathy
- pain following a dermatomal pattern
- sharp and stabbing
- sensation loss according to a dermatome C7 nerve root and C8 and C6 are normal (test uninvolved side first)
how to examine a nerve root injury
- hyporeflexia
- diminished myotomes
- diminished DTR
testing for a LMN injury - peripheral nerve
- locate the specific level of the injury
- Tinels sign
- nerve follows the peripheral nerve pathway
- muscle and sensory loss below the level of injury
- weakness and hyporeflexia
injury to the common fibular n muscles involved
TA EHL EDL
injury to the common fib clinical presentation
- hypo reflexia
- Musclular weakness along n distribution
- sensory loss in common fib
Injury to the common fib signs and symptoms
- numbness and tingling
- shooting pain along the n
- pain with nerve tapping
- pain at rest
Muscle strength in LMN lesion
weakness/ paralysis
muscle tone in LMN lesion
decreased
reflex strength the LMN lesion
decreased
Muscle wasting in LMN lesion
rapid muscle wasting
