Sport-related concussion: How best to help young athletes

Concussion management: Rest is key

While there is a dearth of high-quality studies on the management of sport-related concussion across all age groups, standardized protocols for both children and adults have been adopted in most clinical settings.^8-10,16,17 The protocols provide a framework for an individualized treatment plan. Yet their use among primary care physicians is inconsistent.^18-20

Traditionally, concussion management begins with relative physical and cognitive rest to allow the brain time to recover.^8-10 Recent randomized controlled trials have challenged this premise by suggesting that mild to moderate physical activity for post-concussion patients who are mildly symptomatic does not adversely affect recovery.^21,22 These studies have significant limitations, however, and further research is needed to provide specific guidance on this aspect of concussion management before it is adopted.

Physical restrictions include organized sports, recreational activity, recess, and physical education classes. Walking is permitted unless it exacerbates symptoms. These restrictions should continue until the patient is symptom-free.

Recent trials suggest that mild to moderate physical activity for mildly symptomatic post-concussion patients does not adversely affect recovery.

Cognitive restrictions include modifications at school and at home. Once an athlete is able to concentrate and tolerate visual and auditory stimuli, he or she may return to school. But classroom modifications should be considered, possibly including shortened school days, extra time for testing and homework, help with note taking, and restrictions from classes likely to provoke symptoms, such as computer science or music. Limiting use of mobile devices, television viewing, noisy environments, and other possible provocations may help speed symptom resolution. These restrictions, too, should remain in place until the patient is symptom-free.

Driving is often not addressed by physicians managing the care of athletes with concussion, but evidence suggests it should be. A study of patients presenting to the emergency department found that within 24 hours of a concussion diagnosis, individuals had an impaired response to traffic hazards.^23,24 And Canadian clinical practice guidelines recommend that athletes with mild traumatic brain injury (TBI) avoid driving within the first 24 hours.²⁵

While American guidelines are silent on the question of driving for this patient population, we recommend that athletes with concussion be restricted from driving and engaging in other risky complex tasks, such as welding or shop class, for at least 24 hours. For many athletes diagnosed with concussion, driving restrictions of longer duration may be necessary based on their symptom profile and neurocognitive test results. Continued dizziness or visual deficits would pose a greater risk than fatigue or short-term memory loss, for example.
