text: The percentage of high school athletes sustaining a concussion who had previously sustained a sports-related concussion either that season or in a previous season is holding steady at about 11%: in two studies released in 2011, the first 4 covering the 11-year period from 1997 to 2008 at high schools in one large suburban school district, each with an athletic trainer, and the second 8 covering the 2009-2010 school year for a representative sample of U.S. high schools with athletic trainers, both found that 11% of concussions in the high school sports studied were repeat concussions; the most recent study of concussions in high school sports 10 reported that 11.5% of concussions were of the recurrent variety.
