What is King-Devick Test?
Published medical studies have determined that deficiencies in saccadic eye movements can be an indicator of mild Traumatic Brain Injury (mTBI) or concussions. Recent studies published in Neurology and the Journal of The Neurological Sciences have determined that post head-trauma related deficiency in the King-Devick Test is an indicator of mild TBI or concussions.
