Eye motion testing provides insight into the pathways of the brain.
The King-Devick Test (K-D Test) is a two-minute test that requires an athlete to read single digit numbers displayed on an iPad. After suspected head trauma, the athlete is given the test and if the time needed to complete the test is any longer than the athlete’s baseline test time, impairment is noted. The K-D Test detects changes through the motions of the eyes, which is often affected after receiving a concussion.
