abstract="Concussion is the most common head injury in sports. The injury ranges from a simple &quot;ding&quot; to prolonged loss of consciousness with amnesia. Proper grading of the severity of the injury is necessary to establish a protocol for deciding when to allow an athlete to return to his or her sport.
