Diagnosis and Sideline Management of Sport-Related Concussion.

The diagnosis of sport-related concussion is still based primarily on history and physical examination. Use of a standardized history and examination form is recommended. There have been many tests investigated, but none have been proven to be sensitive and specific for the diagnosis of concussion. Sideline management is based on recognition, diagnosis, and initial treatment. It is clear that symptoms of a concussion can worsen with continued play, and so, if a concussion is suspected based on observation, history, and physical examination, then the athlete should be removed from play.
