A complete spinal injury occurs when the spinal cord is fully damaged, resulting in a total loss of sensation and motor function below the injury site. This type of injury can lead to paralysis, affecting the limbs and body functions depending on the location of the injury along the spinal column. Individuals with a complete spinal injury may experience quadriplegia if the injury is in the cervical region or paraplegia if it occurs in the thoracic or lumbar regions. Rehabilitation and support are crucial for managing daily activities and improving quality of life after such an injury.
