2.29 SCI 3 Flashcards
What MMT scores mean full innervation?
3, 4, 5
lower MMT score than 3
lower than this means partial or no innervation
ASIA scale: line drawing
- 3 or 4, draw a line below
- 2 or 1 or 0, draw a line above it
ASIA impairment scale
A-E
ASIA impairment scale: A
no motor or sensory function preserved in S4-5
ASIA impairment scale: B
- sensory but not motor function is preserved below the neurological level
- includes S4-5
ASIA impairment scale: C
- motor function preserved below neurological level of injury
- more than half of key muscles below the neurological level have a grade less than 3
ASIA impairment scale: D
- motor function preserved below neurological level of injury
- at least half of key muscles below the level of injury have a grade of at least 3
- tells us they have motor and good strength below the level
ASIA impairment scale: E
motor and sensory function normal
benefit to using ASIA scale
helps us be able to classify incomplete injuries
How would an SCI pt go from B to C?
they have to have motor function below the level
ZPP
zones of partial preservation
What are ZPPs for? How do you find them?
- For complete injuries ONLY
- lowest motor and lowest sensory level with ANYTHING occurring
- add up numbers for motor score on R and L
How do you interpret ZPP score?
higher the number, the more is working (DUH)
Brown Sequard
- ipsilateral loss of deep, discriminitive touch, motor, etc.
- contralateral motor
central cord patient
- outermost part of the cord is intact, central cord is where damage has occurred
- profound weakness in UE and have strength in LE
- bed mobility difficult, sit to stand difficult
How does a central cord pt walk?
like a penguin
Can central cord pts learn to walk again?
yes
anterior cord syndrome
- variable loss of motor
- variable loss of deep/crude touch
- posterior portion intact, so they still have proprioception
posterior cord syndrome
- rarely seen
- gets rid of proprioception
- have motor and deep/crude touch
posterior cord syndrome: what does this look like?
- tend to stomp, trying to get any sensory information they can
- don’t know where to put their limbs when walking
- used to see it a lot with tertiary syphilis
cauda equina/conus medullaris SCI
- might have LE weakness
- typically affect bowel and bladder
