Accurate on-field identification of concussion entails education of athletic trainers, coaches, health-care professionals, parents, and athletes to ensure that common acute symptoms are readily recognized.

In cases of suspected head injury, an instrument such as the Sport Concussion Assessment Tool (SCAT2) should be used to evaluate the athlete.13 The SCAT2 is a standardized method of evaluating injured athletes for concussion and can be used in individuals aged 10 years and older. 


Any sports participant that is suspected of having a concussion must be removed from play. Other assessment tools that can be used on the field include testing for orientation (“What team are you playing? What is the score?”), concentration (word/number recall), and neurologic defects (speech, eye movement, balance). 


Emergency evaluation


Any athlete that elicits signs of neurologic deterioration must undergo a detailed evaluation in the ED. This examination should include a thorough neurologic history. The clinician should obtain information from the athlete, parents, and any teammates that can add pertinent facts to your assessment. The need for emergent neuroimaging to exclude severe brain injury must be determined; not every athlete who sustains a TBI requires imaging. In general, imaging is required if there is a suspicion of intracerebral structural lesions, prolonged loss of consciousness lasting longer than one minute, focal neurologic deficits, worsening of symptoms, repeated and uncontrolled vomiting, or persistent cognitive symptoms.7 There has been recent research on the use of functional MRI, positron emission tomography (PET) scans and diffusion tensor imaging of sports-related concussion in adolescents.14 Unfortunately, there are no imaging techniques that can diagnose a concussion.


When to return to play


The cornerstone of concussion management is physical and cognitive rest. Activities that require attention and concentration must be limited so not to exacerbate symptoms. Cognitive rest activities include limiting use of computers, cell phones (texting), video games, watching television, and even socializing with friends. 


At the Third International Conference on Concussion in Sport, a stepwise protocol for return to play was recommended (Table 2).7 The protocol begins with no activity or complete rest until the concussed athlete is asymptomatic. Once asymptomatic, light aerobic exercise with no resistance training is allowed. If the athlete continues to be asymptomatic, he or she is allowed to move on to the next step. Each remaining stage must be completed without symptoms returning over a 24-hour period. If symptoms reappear, the athlete must go back to the preceding stage until asymptomatic and then restart the stepwise progression. Once the athlete can complete noncontact drills without experiencing symptoms, he or she is medically cleared to begin full contact drills and return to competition.16

What else can clinicians do?


Above all, educate the athlete and his or her parent on the serious nature of concussions. Explain the facts about the injury and provide realistic expectations. Emphasize the fact that activities that require concentration and attention (e.g., schoolwork, videogames, television, text messaging) may exacerbate concussion symptoms and possibly delay recovery. Provide a reminder that an injury to the developing brain may increase the risk of long-term effects in children and adolescents. No athlete who suffers even a mild concussion should ever return to play on the same day of an injury. When in doubt, sit them out.
