Assignment task: Steve went to a neurologist. The neurologist examined him and found no problems with Steve's speech, his cranial nerves, or the sensory or motor function of his arms. His left leg was extremely weak, and the knee-jerk and ankle-jerk reflexes were very brisk. Whereas vibration and position senses were absent on the left leg, pain and temperature senses were absent on the right leg. Pain sensation, when tested with a pinprick, was absent on the right aspect of the trunk below the level of the umbilicus, and, at this level, there was also some segmental bilateral loss of pain sensation. When the lateral plantar surface of Steve's left foot was scratched, the great toe dorsiflexed, and the other toes fanned. When this maneuver was repeated on the opposite side, the toes curled under.
