What is the difference between complete and incomplete spinal cord injury?

The distinction between complete and incomplete spinal cord injuries is primarily based on the degree of loss of function that occurs below the level of the injury. In the case of a complete spinal cord injury, there is a total loss of motor and sensory function below the injury site. This means that the individual has no ability to move or feel anything in the areas of the body that are governed by the spinal segments below the injury.

On the other hand, an incomplete spinal cord injury allows for some preserved functioning below the injury level. This could mean that the person retains some degree of movement or sensation, which can vary significantly from one individual to another. This difference in functionality is crucial in understanding the potential for recovery and rehabilitation, as individuals with incomplete injuries may regain some abilities, whereas those with complete injuries typically do not regain any function.
