In the case of spinal injuries, what does 'complete injury' mean?

A 'complete injury' in the context of spinal injuries refers to a total loss of both motor and sensory function below the level of the injury. This means that any nerves that relay information from the affected part of the spinal cord to the brain are completely disrupted. As a result, an individual with a complete injury will have no voluntary muscle movement or sensation in the areas of the body that are innervated by the spinal segments below the level of the injury.

This definition is crucial for medical practitioners and rehabilitation specialists, as it helps determine the prognosis and potential for recovery. A complete injury generally indicates a more severe impairment compared to partial injuries, where some degree of sensation or movement is preserved. Understanding the difference between complete and incomplete injuries is fundamental for developing effective treatment plans and setting realistic rehabilitation goals.
