ASIA Flashcards
ASIA is for patients older than __________
and should be performed __________ post injury
4 years old
72 hours
Light touch tests what column?
How is the patient positioned?
What pattern do you follow?
DMCL
Supine
Rostral to Caudal, test all of one side first followed by the other side
What counts as a 1/2 for light touch
Patient reports being touched but it feels different than the control (face)
What column does pin prick test?
How do you test it?
How many correct answers is considered normal
Spinothalamic
Randomly alternate between sharp and dull 10 times
8/10
What is considered a 1/2 for sharp/dull testing
Patient can accurately distinguish between sharp/dull 8/10 times or more but reports it feels different than face
__________ Defines an incomplete spinal cord injury
Any anal sensation or voluntary anal contraction
________________ reliably predicted independent walking when performed 8-31 days after injury
Pin prick sensation at heel (S1)
L+R intact = 9/10 will independently walk
L or R = 8/10 will independently walk
Neither = 8/10 will not independently walk
C4: 2 C4: 2
C5: 2 C5: 2
C6: 1 C6: 1
C7: 1 C7: 0
What is the sensory level?
C5
The sensory level is the most caudal segment of the spinal cord with 2/2 for pin prick and light touch
What muscle groups correspond with C5, C6, and C7 on the ASIA scale
Elbow flexor
Wrist Extensor
Elbow Extensor
What muscle groups correspond with C8 and T1
Finger flexors to the middle finger
Small finger abductor
What muscle groups coorespond to L2, L3, and L4 on ASIA
Hip flexor
Knee Extensor
Ankle dorsiflexor
What muscle groups correspond to L5 and S1 on asia
Long toe extensor
ankle plantarflexor
How do you determine the motor level if the UE is intact, the LE is all 0s, and your sensory level is in the thoracic spine?
2/2 sensory = you assume motor is intact at that level aswell
so if the sensory level is T9 and there is no motor at L2-S1, you assume that the motor level is also T9
What is the motor level:
C5: 5
C6: 5
C7: 4
C8: 2
T1: 0
Motor level is C7, the motor level is the first score above 3 that has a 5 above it
Special rule for L2 and C5 motor level
Since there is no motor test for C4 and L1, you will assume these levels are 5/5 if they have intact sensory
So therefore if C4 Sensory is intact, and C5 motor score is a 3/5…
C5 is the motor level
How do you determine the neurological level in ASIA
Most caudal segment (lowest) with both normal motor and sensory bilaterally
95/147
