Spinal cord injury [SEP] Signs and symptoms
A group of muscles innervated through a specific part of the spine is called a myotome, and injury to that part of the spinal cord can cause problems with movements that involve those muscles. The muscles may contract uncontrollably (spasticity), become weak, or be completely paralysed. Spinal shock, loss of neural activity including reflexes below the level of injury, occurs shortly after the injury and usually goes away within a day. Priapism, an erection of the penis may be a sign of acute spinal cord injury.
