A comprehensive system of classification of clinical outcome of traumatic spinal cord injury.[67]Kirshblum SC, Burns SP, Biering-Sorensen F, et al.

• A (complete): no motor or sensory function in the lowest sacral segment (S4-S5).

• B (incomplete): sensory function below neurologic level and in S4-S5; no motor function below neurologic level.

• C (incomplete): motor function is preserved below neurologic level, and more than one half of the key muscle groups below neurologic level have a muscle grade <3.

• D (incomplete): motor function is preserved below neurologic level, and at least one half of the key muscle groups below neurologic level have a muscle grade ≥3.

• E (normal): sensory and motor function is normal.
