The King-Devick test is a tool used in concussion baseline and post injury sideline assessment. The test measures saccades, a type of eye movement where both eyes jump quickly from point to point, or in the case of the King-Devick test, number to number. These functions are sometimes impaired after a concussion.1
In addition to saccadic eye movement, the King-Devick test measures:
- Visual Processing
The King-Devick test consists of a series of number charts which are read aloud by the test taker and timed by an instructor. The test requires rapid eye movement, language processing, and ability to focus.
