What Is ASIA Impairment Scale

1. WHAT EXACTLY MEANS “BELOW NEUROLOGICAL LEVEL”?

2. Hi,
   I would like to ask about AIS calssification problem. If the patient below the neurological level one muscle have grade 1 and other musle are 0 nad anal sensation is “yes”. Is he AIS B or C.
   AIS C, half of the muscles have grade less than 3, are the grade 0-2. Should there be activity half of the key muscles?

3. B = Sensory incomplete. Sensory but not motor function
   is preserved below the neurological level and includes the
   sacral segments S4-S5, AND no motor function is preserved
   more than three levels below the motor level on
   either side of the body.
   C = Motor incomplete. Motor function is preserved
   below the neurological level, and more than half of
   key muscle functions below the single neurological level
   of injury have a muscle grade less than 3 (Grades 0–2).
   For an individual to receive a grade of C or D, i.e.
   motor incomplete status, they must have either (1)
   voluntary anal sphincter contraction or (2) sacral
   sensory sparing (at S4/5 or DAP) with sparing of
   motor function more than three levels below the
   motor level for that side of the body. The Standards at
   this time allows even non-key muscle function more
   than 3 levels below the motor level to be used in determining
   motor incomplete status (AIS B versus C). (from 2011 revised AIS)

4. I would like to ask one doubt regarding sensory assessment in Asia scale…. why we are checking only pinprick and light touch for sensory assessement

5. The light touch tells us whether the anterior spinothalamic tract is intact and the pinprick tells us whether or not the lateral spinothalmic tract is functioning. These are both sensory pathways that are found in the spinal cord.

6. […] The difference between paraplegics, quadriplegics, hemiplegics, tetraplegics, and what the ASIA scale […]
