Summary: For children between ages 5 and 18 years old who have experienced an acute concussion, early participation in physical activity within 7 days of the injury may be associated with a lower risk of persistent postconcussive symptoms (PPCS) at 28 days post-injury than an approach of having no physical activity within the first 7 days post-concussion.

Note – the authors of this study emphasize that 1) caution in the immediate post-injury period remains vital, 2) activities that entail a risk of repeat head injury should remain prohibited in the early post-concussion period, and 3) an adequate randomized controlled is needed to better understand the benefits of early physical activity following concussion.
