complete spinal cord injury

[Laurie J. Lundy-Ekman]

Do people with complete spinal cord injury sometimes have withdrawal 
reflexes below the level of the lesion that move the limb away from a 
sharp nociceptive stimulus?  If so, why don't protective reflexes move 
the limb away from excessive heat?  A former patient of mine was badly 
burned by a radiator, and I don't understand why reflexive spinal cord 
circuitry didn't move the limb at least briefly. Thanks - Laurie Lundy-Ekman
