Strict physical and cognitive rest in the five days immediately after concussion does not help teens recover more quickly than taking it easy for one to two days after injury and then returning to school, finds a new study. (Thomas, 2015)  

The mainstay of concussion management for children and teens is both cognitive and physical rest after injury followed by a gradual, symptom-limited, return to activity. (Meehan, 2015).  As several medical groups (McCrory, 2013; Halstead, 2010; Giza 2013) have noted, however, the evidence on which the recommendation for rest is based is sparse, due, in part, to the difficult nature of quantifying and tracking levels of physical and, particularly, cognitive activity.
