Final answer:
Mr. Wright's spinal cord injury is classified as an incomplete injury, as some sensation has returned. The correct answer is option B).
Step-by-step explanation:
Since Mr. Wright's spinal cord injury is showing signs of some sensation returning, his injury would be classified as incomplete. An incomplete spinal cord injury is one where there is some function or sensation below the level of the injury. In contrast, a complete spinal cord injury would result in no function or sensation below the level of injury.
Sensation and movement are indicative that some nerve pathways are intact, signaling that the injury is not complete. Considering a specific scenario where a motorcycle accident victim loses the ability to move the right leg but can control the left leg indicates a hemisection.
In this case, one would expect sensory deficits where pain stimuli might be perceived on the damaged side of the body but not fine touch. Conversely, fine touch would be intact on the side opposite the injury, where the dorsal column medial lemniscus pathway remains intact.
