AIS: ASIA Impairment Scale; ASIA: American Spinal Cord Injury Association. A: no motor or sensory function is preserved below the neurological level; B: sensory function is preserved but no motor function below the neurological level; C: motor function is preserved below the neurological level, and more than half of the key muscles below the neurological level have a muscle out of 5 (manual muscle testing); D: motor function is preserved below the neurological level, and at least half of the key muscles below the neurological level have a muscle grade of ≥3 out of 5, E: motor and sensory function are normal. WUSPI: Wheelchair User’s Pain Index.
