Spinal Cord Injury Flashcards
ASIA A
no sensory or motor below the neuro level
NOOON sign
What is ASIA B?
What does the DCML?
light touch, proprioception, vibration and pressure
What does STT do?
pain and temperature
What is the descending tracts?
lateral and anterior corticospinal tract= motor control the contralateral side of the body
What is the corticospinal tract
voluntary motor, fine coordinated movement
What is anterior cord syndrome?
due to the anterior spinal artery being compressed
affects motor – paralysis
can affect STT
What is posterior cord syndrome?
damage is towards the back
good muscle power, pain and temperature
difficulty in coordinating movement of the limbs
What is central cord syndrome?
due to hyperextension of the C-spine
disproportional greater UL weakness – due to region of corticospinal tract
sensory loss is minimal
some control of bowel and bladder
What is Brown sequard syndrome
hemisection of the SC
ipsilateral– impaired or loss of movement, preserved pain and temperature sensation
contralateral– normal movement, impaired pain and temperature
What is conus medullary syndrome?
bowel, bladder and sexual dysfunction
LBP
leg pain
diminshed rectal tone
What is cauda equina syndrome?
injury to nerve roots below L2
muscle weakness
decreased sensation
decreased bowel and bladder control
What can autonomic dysfunction cause?
neurogenic shock
CV complications
temperature regulation
altered sweat secretion
what is autonnomic dysreflexia (AD)
increase in BP (>20-40 mmHg above baseline) usually associated with bradycardia
What are the causes of of autonomic dysreflexia?
noxious stimulus below the level of injury
vasodilation above level on injury only
vasoconstriction below the level of injury
