Q

How is motorfunction graded in ASIA score?

A

0-5.
0= total paralys
1= palpabel or visible contraction
2= gravity eliminated
3= active movement against gravity
4= active movement against resistance
5= normal corrected for pain.
NT= not testable

Q

How is the sensory function measured?

A

Two entities are scored. 1. Light touch
2. Pin prick. (pain)

Each is given 0-2p
0= abscent
1=altered
2= normal
NT= not testable

19
Q

20
Q

What dermatome is dig 3 (both sides)?

21
Q

WHat dermatome is the inside (closest to the body in anatomical position) of the underarm, down to the wrist?

22
Q

What dermatome is the inside of the arm of the upper arm?

23
Q

What dermatome is the nipple included in?

24
Q

What dermatome is the umbiliqus included in?

25
Q

What dermatome is the groin?

26
Q

What dermatomes are the anal opening?

27
Q

What dermatome is frontside knee?

28
Q

What dermatome is medial frontside underknee down to and including the medial maleolus?

29
Q

What dermatome is the lateral side under knee crossing over and including dig 1-3 of the foot?

A

L5 (observe that L5 also is responsible for big toe dorsoflexion (extension))

30
Q

What dermatome is the heel and middle back to the knee?

31
Q

What dermatome is above S1 on the hindside?

32
Q

What is the ASIA Impairment Scale AIS?

A

Label A-E grade the damage dependent on what came out of the scoring.

33
Q

What is AIS A?

A

Complete injury. No sensory or motor function is preserved in the sacral segments S4-5

34
Q

AIS-B?

A

Sensory incomplete
-Sensory but not motor f is preserved below the neurological level and includes the sacral segments S4-5 (light touch OR pin prick at S4-5 OR deep anal pressure) AND
NO motorfunction is preserved more than three levels below the motorlevel on either side of the body.

35
Q

What is deep anal pressure representing?

A

sensory function at level S4-5

36
Q

What is AIS C?

A

alt 1. Motor function is preserved at the most caudal sacral segments for voluntary anal contraction OR
alt 2: the pt meets criteria for sensory incomplete status and has some sparing of motorfunction more than three levels below the ipsilateral motorlevel on either side of body. -Here non-key motorfunction might need to be evaluated.

For AIS C-less than 1/2 of key muscle functions below the single NLI have a muscle grade of more or equal to 3.

37
Q

What is AIS D?

A

Motor incomplete-
Half or more of KEY musle functions below the single NLI have muscle grade equal to or over 3.

38
Q

AIS E ?

A

Normal. compared to previous injuries. If the patient hasnt had an initial SCI an AIS grade is not given at all.

39
Q

According to ASIA score - how is the sensory level determiined?

A

The most caudal intact dermatome for both pin prick and light touch. (left and right side separate)

40
Q

How is the motorlevel determined in ASIA score?

A

The lowest level where the patient has at least score 3 (and the levels above are 5).

41
Q

What is judged as NLI - neurological level of injury?

A

The most cephalad of the sensory and motorlevels determined. (the lowest level where everything is intact)

42
Q

How is it determined if the injury is complete or incomplete?

A

Sacral sparing!
To be a complete injury all of the following need to be fullfilled
NO voluntary anal contraction
NO deep anal pressure
NO sensory function analy (S4-5) (neither pin prick nor light touch)

43
Q

How is it determined if the injury is MOTOR complete?

A

Then there is no voluntary anal contraction OR
any motor function more than three levels below the motor level on a given side, if the patient has sensory incomplete classification.
