Br J Sports Med. 2013;47(5):304-307. After concussion and a period of symptom-limited physical and cognitive rest, do athletes who experience intermittent symptoms return to asymptomatic condition more quickly with physical activity than with prolonged physical rest? One investigator performed an individual search for each research question using the following databases: CINAHL, Cochrane Controlled Trials Registers, EMBASE, HealthSTAR, ProQuest, PsychInfo, PubMed, SPORTDiscus, and Web of Science. Search terms for rest were brain concussion, cognitive rest, mild traumatic brain injury, physical exertion, postconcussive syndrome, rehabilitation, sport-related concussion, therapy, treatment, and treatment outcome. Search terms for treatment were the same terms as for rest, as well as brain training, cervical spine, cognitive therapy, dizziness, exercise, headache, neck, pharmacotherapy, postural balance, and vertigo. The authors included peer-reviewed, published articles and abstracts and performed a citation search. Studies were included based on the following criteria as determined before searching: classified as original research, symptoms resulted after sport-related concussion, and investigation of the effects of either rest or treatment on symptoms. Abstracts that were excluded failed to evaluate rest, omitted sport-related concussion as the cause of symptoms, failed to evaluate a treatment’s effect on sport-related concussion, or did not present original research.
