Cervical cord injury is often characterized by quadriplegia, loss of sensation below the neck, incontinence, dyspnea, lack of sweating, and elevated or lowered body temperature. Thoracic medulla injury, mostly manifested as complete paralysis of the lower limbs, loss of sensation, urinary and fecal incontinence, slow heart rate, low blood pressure, paroxysmal spasm of the lower limbs. If the injury is in the upper thoracic medulla, dyspnea may also occur. After lumbar spinal cord injury, most will have complete paralysis of the lower limbs, loss of sensation, and loss of bowel control. In spinal cord cone injury, the sensory and motor functions of the lower limbs are mostly normal, but urinary and fecal incontinence and part of the perineal skin sensation will still be reduced or lost.
