Assessment
of the level of injury must be undertaken. If the patient
is conscious, ask questions relevant to his or her sensation.
Check the motor function of the upper and lower extremities
by asking the patient to do minor movements.
The following summarizes key reflex assessment to determine the level of lesion.

If
no sensory or motor function is exhibited with a complete spinal
cord lesion, the chance of recovery is small.
Loss of autonomic function with spinal cord injury
may occur rapidly and resolve slowly.
