Visual tracking problems and silent concussions - WHY parents, the public and Optometrists need to know
Therefore, knowing that concussions can be identified 100% of the time with the King-Devick Test, here is another question for parents and the public to ask. Why are we not routinely administering the King-Devick Testing on children, 6 years and older, so that their optometric record establishes baseline in saccadic eye movement?
Participants will take the King-Devick Test, which provides an objective measure of reaction time, eye movement and mental clarity.
The King-Devick test may be a more objective and accurate method for sideline evaluation of sports-related concussion than the Standardized Concussion Assessment Tool 3 (SCAT3), which is the current standard, according to research reported at the 56th Annual Scientific Meeting of the American Headache Society.
In the new study, Mayo Clinic researchers tested the feasibility of using a portable eye-tracking device [King-Devick Test] in a simulated environment as a way to detect the early phases of hypoxia.

In an article published this month in the journal “Neurology: Clinical Practice,” the researchers report that adding one simple vision test detected 100 percent of concussions that occurred during games or in practice.

“This is the first study that has shown that adding a vision test helps to identify more athletes with concussion and shows the vision-based King-Devick test is very effective in a college setting,” said Dr. Laura Balcer, a professor of neurology and population health at NYU.
About 1,200 students at Loyola High School, including non-athlete students, are being given a series of tests, known as baseline concussion test, designed to measure brain function.

Patients who are dealing with symptoms such as balance issues and vision problems are often referred to a neurologist such as Dr. Laura Balcer, who has done pioneering research on the link between eye movement and brain function.
CMCC & Rugby Ontario Partner to Administer Baseline Concussion Measures For More Than 235 Junior Provincial Athletes
Canadian Memorial Chiropractic College in Toronto volunteered their day to aid in the administration of baseline concussion measures with seven different Rugby Ontario junior provincial teams for over 235 athletes.

"The results of this pilot study suggest that the King-Devick remediation software may be effective in significantly improving reading fluency through rigorous practice of eye movements," Amaal Starling, MD, Mayo Clinic neurologist and a co-author of the study, said in the release.
“The results of this pilot study suggest that the King-Devick remediation software may be effective in significantly improving reading fluency through rigorous practice of eye movements,” says Dr. Starling. “What our study also found was that there was an even greater improvement between first and third grade versus third and fourth graders, which means there may be a critical learning period that will determine reading proficiency.”
“Given the many brain pathways involved in concussion, we think that a combination of cognitive, balance and vision tests may be best to improve diagnosis of concussion in athletes,” says Laura Balcer, MD, Fellow of AAN, professor and vice chair of neurology at New York University Langone Medical Center.
Dr. Devick is committed to making reliable and objective sideline concussion testing for all athletes accessible and affordable. "The King-Devick Test helps provide a safer sporting environment for youth athletes by accurately screening for concussion," he says. "It's our responsibility as parents, coaches and clinicians to identify concussions in order to remove them from play and allow children the proper time to recover from concussion so they can safely return to learn and play."

Dr. Amaal Starling of the Mayo Clinic is co-author of the study. She said for youth athletes, "This is really the first accurate, rapid, cost effective, removal-from-play tool that is available for concussion screen."
Concussions and their treatment have become major topic in the sports world, but there is a new test called the "King-Devick" that might help faster detect when a player gets a concussion.
Kyle Burger spoke with Dr. Larry Lemak and Dr. Mark Schaeffer about the new test.
“The King-Devick test represents a rapid, accurate, and cost-effective tool to identify concussion on the sideline and make appropriate game-time, remove-from-play decisions,” Dr. Amaal Starling says.
Balancing fun and competition with safety, Ernest Murdukhayev, a director of SB4U Soccer Academy and the Jewish Community Center programs, is using the King-Devick test to assess the seriousness of any head bangs his players encounter.

Neurologists now propose using the King-Devick vision test in the pre-season. This test takes about a minute and involves a timed reading of numbers from an iPad or from index cards. If a suspected concussion occurs during a sporting event, the test is administered, along with the usual balance and cognition tests, at the sidelines. Deviation from the baseline results can be diagnostic for concussion. Imaging and other testing in a hospital may be necessary.

"I do think this is enough to recommend this vision test be used routinely," Dr. Clugston commented. "This test is less subjective than some of the other tests used currently. An assessment of balance is always very subjective, and cognition tests can be too. But the vision test just involves reading numbers from a screen as fast you can. It is very simple and less easily manipulated by the athlete. But it is best used in combination with the standard tests."
Researchers found the time to complete the test was longer for 79-percent of players who were later found to have a concussion. When combined with other assessments, the sideline test helped diagnose 100-percent of concussions. Experts say using a vision based test on the sidelines may help detect concussions more quickly ... and keep athletes from getting injured further.

The King-Devick test capitalizes on a subtle but important symptom of brain injury: a disruption in the eyes' ability to travel smoothly across a page, and to shift direction upon the brain's command.
The study provides more evidence that the King-Devick test, a one-minute test where athletes read single-digit numbers on index cards, can be used in addition to other tests to increase the accuracy in diagnosing concussion.

New research presented at the American Academy of Neurology's 66th Annual Meeting in Philadelphia indicates that a quick vision test, known as the King-Devick test, combined with a series of other simple tests, could yield near-perfect concussion detection rates on the sidelines of a game.
