Baseline screenings include cognitive and balance tests, as well as a vision measure known as the King-Devick Test — a two-minute challenge during which an athlete is asked to read single-digit numbers on cards or an electronic device. After a hit or suspected concussion, the athlete retakes the test. If he or she takes longer than their baseline, the athlete is removed from play for further evaluation. UF was one of the first schools to implement the King-Devick Test as part of the concussion-management program.
