During high-risk sports events, it is important for team physicians to
be alert to the possibility of concussion in athletes who may not rea
lize they have been injured or may want to conceal their injury. If co
ncussion is suspected and the player is conscious, history taking shou
ld include inquiries about loss of consciousness, loss of memory of ev
ents before and after the impact, headache, visual abnormalities, moto
r and sensory changes, and back, neck, and extremity pain. In an uncon
scious player, the airway, breathing, circulation, and cervical spine
should be checked. The cervical spine must be stabilized before the pl
ayer is moved if injury to it is suspected. Athletes with such an inju
ry and those who have lost consciousness require hospital evaluation.
If there is no cervical spine injury, a complete neurologic evaluation
should be carried out on the sidelines and the player checked for sig
ns of skull fracture. The Colorado Medical Society guidelines for grad
ing concussions and deciding when athletes may return to competition a
re an excellent aid to clinical judgment.
