Correlating the King-Devick Test With Vestibular/Ocular MotorScreening in Adolescent Patients With Concussion: A Pilot Study

摘要

Background:The King-Devick (K-D) test is a rapid number-naming task that has been well validated as a sensitive sideline performance measure for concussion detection. Patients with concussion take significantly longer to complete the K-D test than healthy controls. Previous research suggests that ocular motor deficits, specifically saccadic abnormalities, may be an underlying factor for the prolonged time. However, these findings have not been studied at length.
