A spinal concussion involves trauma to the spinal cord where the injured individual experiences temporary neurological disturbances in terms of motor and sensory functions, notes the Cleveland Clinic. The condition is generally reversible and resolves itself within 24 hours.
Concussion to the spinal cord is known in medical jargon as cervical cord neurapraxia (CCN). In the United States, CCN is a common sports injury in football, affecting seven out of every 10,000 athletes.
Frequently observed symptoms of CCN include a tingling sensation in the limbs, numbness, weakness or even short-term paralysis of the entire body. As of 2015, the lasting effect of repeated CCN injuries is still undetermined, notes the Cleveland Clinic.
