|Short Description of Instrument||
Purpose: The ASIA Motor Scale is used to illustrate the severity of spinal cord injuries and to help inform the direction of future rehabilitation or recovery. Patients' are graded based on the amount of sensation that can be felt at multiple points on the body (five on the upper limb; five on the lower limb on each side of the body), as well as more general motor function tests.
Instructions: The tests should be completed by a physician and filled out within the first 72 hours of the spinal injury.
Scale: This scale is rated using a five-point grade, from A to E, wherein the lower the grade the more severe the injury. The scale is as follows:
Grading: There are 10 key muscles tested (five in the upper limb and five in the lower) on both sides of the body, testing 20 muscles total. This is then scored on a 100-point scale, in which 100 is a perfect score and indicates that the patient has no weaknesses.
This is the most widely used scale to assess motor function and, as such, has been extensively used and validated.
