This test evaluates visual tracking and saccadic eye movements.
Based on the time to perform rapid number naming, this test involves reading aloud a series of single digit numbers from left to right on three test cards.
Participants are instructed to read the numbers on each card from left to right as quickly as possible but without making any errors.
The sum of the three test card time scores constitutes the summary score for the entire test.
The King–Devick Test is also an accurate and reliable method for identifying athletes with head trauma, and is a rapid sideline screening test for concussion.
