ASIA Exam Flashcards
when should the asia exam be done
within 72 hours
grading for sensation
2 =
1 =
0 =
normal
altered
absent
what position is the motor exam performed in
supine
what are the muscles for the motor exam?
C5
C6
C7
C8
T1
L2
L3
L4
L5
S1
elbow flexors
wrist extensors
elbow extensors
finger flexors
finger abduction (little finger)
hip flexors
knee extensors
dorsiflexors
toe extensors
plantarflexors
why are those specific muscles selected for the motor exam
- muscle function or action was needed to represent each SC segment
- each muscle has functional significance
- easily accessible and isolated in supine
- each muscle has innervation of at least 2 spinal segments
what do non-key muscles help do
help definitely classify AIS-B vs AIS-C
also helpful in determining functional capabilities
if >3 levels below and there is motor function, classification is better
what does the neurological level do
predicts which parts of the body may be affected by paralysis and loss of function
used for prognostic indicators and expected functional capabilities
how is NLI determined
evaluating motor, sensory function and sacral reflex
peri-anal sensation
external
S3, S4-5 light touch, sharp dull
deep anal pressure
internal
pressure applied to anorectal wall
voluntary anal contraction
pt able to tight and relax anal muscles on comand
preserved sacral sensory or motor =
sacral sparing
classification A
no sensory or motor in sacral segments
ZPP may be present
does ZPP change prognosis?
no
sensory ZPP is defined as …
in the absence of sensory function in S4-5
