AIS, ASIA Impairment Scale; EMG, electromyography. Letter categories of the AIS are as follows: A, complete; B, sensory incomplete; C, motor incomplete (less than half of the muscles below the injury level have muscle strength ≥ 3); D, motor incomplete (more than half of the muscles below the injury level have muscle strength ≥ 3).
