Physical activity still seemed to reduce chances for lingering symptoms a month after the concussion. “It’s still important to have caution in the immediate post-injury period,” said lead author Dr. Roger Zemek, an emergency medicine specialist at Children’s Hospital of Eastern Ontario. After a sports-related concussion, kids “should always be removed from play and not return that day.” To avoid re-injury, kids should generally be sidelined from the sport or activity that led to the concussion until a doctor clears them to return, he said. But the study results suggest they can resume sports or other physical activities sooner than previously thought, he said. The researchers surveyed about 2,400 kids aged 5 to 18 treated for concussions in nine emergency departments in Canada. Most were sports-related injuries and most kids had at least one concussion symptom in the first week. Results from the 2013-2015 study were published Tuesday in the Journal of the American Medical Association . Current guidelines recommend rest until symptoms disappear to avoid additional concussions, which can increase chances for permanent brain damage. But an editorial published with the study says that advice “”has resulted in some athletes resting for weeks or months, at which point rest may be less helpful and perhaps even harmful.” The study authors say resuming physical activity may increase blood flow to the brain, while inactivity may deprive patients of not only that benefit but also the psychological benefits of activities they enjoy. Patients in the study and their parents were asked about symptoms and physical activity at seven and 28 days after the concussion In the early-activity group, 29 percent reported ongoing or worsening symptoms 28 days after concussions versus 40 percent of the group reporting no extra physical activity beyond daily living activities.
