There’s No Such Thing As A Tough Brain!

The King-Devick Test is an objective remove-from-play sideline concussion screening test that can be administered by parents and coaches in minutes. The King-Devick Test is an accurate and reliable method for identifying athletes with head trauma and has particular relevance to: Football, Hockey, Soccer, Basketball, Lacrosse, Rugby, Baseball, Softball and All Other Contact and Collision Activities.
King-Devick Test is an easy-to-administer test which is given on the sidelines of sporting events to aid in the detection of concussions in athletes. King-Devick Test (K-D Test) can help to objectively determine whether players should be removed from games. As a result, King-Devick Test can help prevent the serious consequences of repetitive concussions resulting from an athlete returning to play after a head injury.

How King-Devick Test Works

Concussions are a complex type of brain injury that is not visible on routine scans of the brain, yet are detectable when important aspects of brain function are measured. King-Devick Test (K-D Test) is a two-minute test that requires an athlete to read single digit numbers displayed on a tablet or 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, the athlete should be removed from play and should be evaluated by a licensed professional.

Screening For Impairments

Did you know that the eyes are really part of the brain? Vision alone accounts for >55% of the brain’s pathways.
King-Devick Test Screens For:
  • Saccades (eye movements)
  • Attention
  • Concentration
  • Speech/Language
  • Other correlates of sub-optimal brain function

Remove-From-Play vs. Return-To-Play

Both remove-from-play and return-to-play decisions are crucial in concussion recovery. It is critical to remove a concussed athlete from play in order to prevent further damage. It is also extremely important to keep the athlete from returning to play until they have made a full recovery. There are tools to assist in making both remove-from-play and return-to-play decisions.
King-Devick Test for Remove-From-Play Decisions
  • Quick, objective sideline testing
  • Measures impairments of speech, language and other correlates of suboptimal brain function
  • Instant screening feedback in minutes
  • Administered by parents, coaches, athletic trainers and medical professionals in remove-from-play decisions
Neurocognitive Testing for Return-To-Play Decisions
  • Computerized concussion evaluation system (in the computer lab)
  • Measures verbal and visual memory, processing speed and reaction
  • Tracks recovery of cognitive processes following concussion
  • Assists clinicians in making return-to-play decisions
