Hi Heather!

I’m sorry – I was referring to the practice ASIA 9 under the spinal cord injury module. I now see you are referencing case 9 from the practice exams.

This patient’s injury is AIS D. Because he has either intact sensory or motor at the lowest sacral levels, he has an incomplete injury. If he had no motor function below his neurologic level of injury (T7), his intact deep anal pressure would classify him as B. Because he has motor function distal to his injury, he is either an AIS C or D. More than half of the key muscles are graded as >=3/5, so he is an AIS D.

Sparing of motor function means any motor functioning, so grades of 1/5 would count. The cut-off of 3/5 is used to differentiate between C and D.
