B | Incomplete: Sensory but not motor function is preserved below the affected neurologic (spinal cord) level, including in the sacral segments S4–S5. |
C | Incomplete: Motor function is preserved below the neurologic level, and more than half of key muscles below the neurologic level have a muscle strength grade of < 3. |
D | Incomplete: Motor function is preserved below the neurologic level, and at least half of key muscles below the neurologic level have a muscle grade of ≥ 3. |
E | Normal: Motor and sensory function are normal. |
