ASIA Impairment Scale for Spinal Cord Injury

Grade spinal cord injury using the American Spinal Injury Association (ASIA) Impairment Scale. Grade A: complete (no sensory/motor in S4-S5). Grade B: sensory incomplete. Grade C: motor incomplete, majority key muscles below grade 3. Grade D: motor incomplete, majority key muscles grade 3 or above. Grade E: normal. Neurological level is the most caudal segment with normal function.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Grade spinal cord injury using the American Spinal Injury Association (ASIA) Impairment Scale. Grade A: complete (no sensory/motor in S4-S5). Grade B: sensory incomplete. Grade C: motor incomplete, majority key muscles below grade 3. Grade D: motor incomplete, majority key muscles grade 3 or above. Grade E: normal. Neurological level is the most caudal segment with normal function

Each component has a specific meaning:

  • American Spinal Injury Association Impairment Scale — The american spinal injury association impairment scale recorded for the scenario being assessed.

Note: Interpret the asia impairment scale result against the thresholds and context described above.

How to Use

Enter the American Spinal Injury Association Impairment Scale for the scenario you are assessing. Grade spinal cord injury using the American Spinal Injury Association (ASIA) Impairment Scale. Grade A: complete (no sensory/motor in S4-S5). Grade B: sensory incomplete. Grade C: motor incomplete, majority key muscles below grade 3. Grade D: motor incomplete, majority key muscles grade 3 or above. Grade E: normal. Neurological level is the most caudal segment with normal function. Use the asia impairment scale result to inform your calculation.
