“Our research last year, conducted in concert with the National Football League, showed promising results and that has led the medical staffs from our clubs to conclude that the K-D test is a viable tool and worth implementing across the CFL,” said Kevin McDonald, Vice-President of Football Operations and Player Safety for the CFL.
“There is no substitute for a parent’s judgment, or anyone’s judgment, that a child should come out of a game,” she says. “The KD test is helpful when there’s ambiguity. But there is no be-all and end-all test for concussion.”
“They’re willing to accept a more quantitative test, as opposed to me just saying their balance is off, their speech is off—all the things I could say,” Dorothy Jamison, Athletic Trainer, explained. “This is a nice thing that’s quantitative enough for them to see that, ‘Yes, my child has a concussion’, and the next step is to take them to the doctor.”
EyeTech partnered with the makers of the K-D test this year, enabling clinicians to monitor and measure an athlete's eye movement while taking the test.
In another development, one that is especially encouraging for youth sports leagues that can’t afford to have medical personnel on the sidelines for every game, the Mayo Clinic has endorsed the King-Devick sideline concussion test and will help promote it to youth coaches, parents and athletes.
“Hockey has an additional challenge because one of the things they test for is balance and of course you can't test balance on skates,” said co-creator of the King-Devick Test Steve Devick.
Added Ruben Echemendia, co-chair of the NHL/NHLPA concussion subcommittee: "We look forward to examining the results of this pilot project. It is our hope that the addition of the King-Devick Test will increase our ability to more accurately diagnose concussions in NHL players."
Results from the joint NFL/CFL initiative to beta-test a new sideline concussion-detection screening should be available by late February. So said Jeff Miller, the NFL’s senior VP of health and safety policy, on a Friday conference call. The CFL is sharing results of these “King-Devick” tests with the NFL, and the four-down league is helping to fund analysis to determine whether the tests improve the ability to diagnose concussions.
“After the series, I got out, looked at the scoreboard and it was kind of blurry,” Decius said. “I started to feel a headache.” Student athletic trainers noticed Decius acting confused as he took a breather. They told trainer Rheisa Burke, who gave Decius a quick head trauma evaluation on her iPad called the King-Devick test.
The newly released King-Devick Eye Tracking System provides users with objective, precise and quantifiable eye movement data and graphs by capturing eye movements using the King-Devick Test without the use of goggles, chin rest or bite bar. The King-Devick Eye Tracking System will include a proprietary software package allowing real-time, automated data measurement and output the following oculometrics and visual diagrams: fixations, saccades, blinks and pupillary dynamics. The objectivity of the King-Devick Test software with eye tracking technology gives users the ability to graph eye movement data for comparison, follow-up and progress monitoring.
Baseline screenings include cognitive and balance tests, as well as a vision measure known as the King-Devick Test — a two-minute challenge during which an athlete is asked to read single-digit numbers on cards or an electronic device. After a hit or suspected concussion, the athlete retakes the test. If he or she takes longer than their baseline, the athlete is removed from play for further evaluation. UF was one of the first schools to implement the King-Devick Test as part of the concussion-management program.
The King-Devick test is supposed to be better at determining whether head trauma has occurred.
Recent research suggests that for every sports concussion we know about, five more go undetected, raising the horrifying specter of our young athletes continuing to play with brain injury. Using simple reading tests such as King-Devick, and other cheap instruments we can detect the majority of these potentially horrendous injuries. The key is baseline testing of not just those who receive injuries, but all athletes before, and then during the season, with traditional follow-up when indicated.
Doctors and medical staff attending to games in Pueblo and Fremont Counties are able to quickly call up the King-Devick tests on an iPad and check for a concussion right on the sidelines. Students who are diagnosed with a concussion must then demonstrate a number of progressions before they are cleared to return to play.
There is a King-Devick test which has proven effective. A variety of technologies for use in instant detection of impairment on the sidelines have been developed and more are on the way.
There, the Howe of Fife Rugby Club has gone further than what the Scotland protocols call for. It has introduced the King-Devick test, an exam given to players to help trainers determine with more specificity whether an athlete is impaired and should be evaluated further by a neuro specialist.
Dr. Richard Besser, “Right now they use a simple test that's effective. The standard testing requires a medical professional but there's a simple eye test that many people are using called the King-Devick Test.”
Of 36 schools reporting the most concussions this fall, 11 are part of the MHSAA’s pilot sideline detection programs. Those programs – King-Devick Test – utilize technology to provide on-site testing of athletes who have sustained possible concussions, with results of those examinations then compared against baseline tests taken by athletes previously.
“For us, the test is quick and objective, and players who might otherwise hide symptoms cannot hide a failed King-Devick test score,” says Kaki Schmidt, hockey parent and Safety/Concussion Program director for the Reston Raiders Hockey club. “It is administered rinkside by one of the team’s parent safety volunteers, allowing coaches to continue running the bench.”
That's not a bad response, and it does highlight some of the good things the CFL is doing. The new King-Devick test (the experimental protocol Orridge mentioned) is promising, as is the league's work with Football Canada on the SafeContact program.
A simple reading test could help establish whether a rider has concussion, according to researchers. A timed vision test — known as the King- Devick Test — involves athletes with a suspected head injury reading numbers as quickly as they can off a series of three cards.
Howe of Fife Rugby Club is leading the way in Europe by adding King-Devick Test to the sidelines for player concussion evaluations.
This year's winners were culled from 535 nominations, which were narrowed down by 12 judges to 100 in September and then 10 finalists for the main award and 10 in the Up-and-Comer category, as well as special citations including the 2015 People's Choice Award.
The other research will assess the long-term effects of multiple concussions on jockeys and the effectiveness of the King-Devick test, a visual examination that is used to diagnose concussions, on players in the Canadian Football League. The N.F.L. will look at the results of the study in Canada to determine whether to add the test to sideline concussion protocol.
Dr. Oz explains how this at-home concussion test can determine whether players should be removed from games and seek medical help.
“Our meta-analysis found that if an athlete had a worsening in their time compared to their baseline reading, they were five times more likely to have sustained a concussion,” Balcer said. “The King-Devick test showed a sensitivity of 86% and specificity of 90% in over 100 patients that had concussion and were formally tested on the sidelines.”
The King-Devick test was developed by an optometrist in the Chicago area in the 1970'S and was originally designed to diagnose reading problems with students. But in recent years it has been adopted to diagnose concussions in sports and has received backing of the Mayo Clinic.
"When I was in high school, a running back ran a 4.9 40 and I thought he was the fastest guy around but last year at the NFL combine, a 340-pounder ran a 4.9,'' Devick said, shaking his head. "Football's the only sport that the 6-year-olds play on the same size as the pros. The field's the same size and everybody's bigger, faster, stronger. I tell my friends with kids in contact sports, I would do the test on them every night. … And I think we've made a lot of progress.''
"It's a number system and basically it's an eye pattern system. Kids follow the numbers and they do a baseline test first of all and then they have to be within one second of their baseline to qualify to stay in a game," said Peter Ryan, the athletic director at the school.
“You're not going to put a kid on the field with a sprained ankle when you know that ankle was still sprained and can't move well. Putting them back into an athletic setting when the brain is not ready to go is not going to promote healing whatsoever."
“The fact of the matter is, there is no such thing as a safe sport. You can have high concussion rates in rugby, soccer, basketball. You can have them in all the sports. It’s a matter of what can we do to mitigate it. Studies have shown it’s not usually the first concussion that’s the problem. It’s when the kid goes to return to play and suffers another concussion after that and then another one after that. With something like King-Devick, if we can pull them out when they suffer the initial injury, now we have really reduced their chance to have a real serious injury out of it.”
“We are excited to be a part of this,” Yale Athletic Director Maureen Klocke said. “We have had our share of injuries like everyone else. Players are bigger, stronger and faster and like everyone else knows, the sport has changed. It’s not the sport we played 40 years ago. Everything is so much quicker.”
The CFL and NFL have teamed up to add a two-minute test to standard sideline examinations for suspected concussion, with the aim of quickly determining whether a player should be pulled from the field or can safely return to play.
Stampeders head trainer Michael Gudmundson said it’s really beneficial because you can’t really cheat it. “You have this based on score. You either beat it or you don’t beat it,” Gudmundson said. “This is something that could be used in amateur sport because it’s pretty easy. You literally read numbers and there’s a timer,” Gudmundson said.
An update from Samantha Figueroa of the King-Devick concussion screening test, a rapid eye tracking test was also presented. Expanding on the portability of the King-Devick is now a tablet-based system on the sidelines for players participating in tests, while a mobile APP assists with keeping record of scores.
Extra points - The NFL is partnering with the Canadian Football League this fall to implement and monitor a new concussion test, the King-Devick Test, which is based on eye movement and will be utilized in CFL games. The NFL will contribute funding and help monitor results to help determine if the K-D Test improves the ability to diagnose concussions.
“Advancing the science around concussion diagnosis, prognosis and treatment to improve player health and safety is our priority,” says Dr. Richard Ellenbogen, co-chair of the NFL Head, Neck and Spine Committee. “We engage with the leading international experts and sports leagues to pursue that goal. We are grateful to the CFL, their teams and players for implementing the King-Devick Test this season to determine whether this protocol improves diagnosis and can make football, and all sports, safer.”
Among the 397 students studied, nine were diagnosed with serious concussions and two were not able to return to play during the season. Based on these results the research team determined that the K-D Test is a reliable tool to help trainers and coaches to quickly determine if a player has suffered a concussion.
Pete Ryan, a member of the MHSAA Representative Council, was the test subject for the King-Devick Test, which asks athletes to read single-digit numbers on a tablet to detect changes in eye movement, attention, language and concentration after a hit to the head. “It’s not hard,” said Ryan, who played football for Iron Mountain in 1987. “The idea is that ocular relations can determine if there is a concussion. The average baseline time is between 28 and 40 seconds.”
“These pilot programs are intended to not only improve what’s actually happening on the sidelines at practices and contests in these communities that are part of the pilot programs, they’re intended to spread the word of the need for improved concussion detection across every community,” MHSAA Executive Director John E. “Jack” Roberts said. “We hope these schools involved will become involved in their leagues and conferences and with their peers across the state as we expand the awareness of the need for better sideline detection and provide ways to get it done.”
Concussions which occur but are not discovered put the player at risk for remaining in the game and possibly having another concussion which may be much more serious, since complete recovery from the first concussion had not occurred. This article demonstrates that KDT testing of every player after every sporting event in which a concussion could have occurred, can be an effective tool to determine a player’s removal from play and a resulting referral to the player’s doctor, even if the concussion was not witnessed during the game.
On the sidelines, the test can identify athletes that not only have suffered a full-blown concussion but sub-concussive brain trauma as well. Thus, the test is an excellent "remove-from-play" tool for trainers, coaches and parents. An effective remove-from-play tool is critical because it can help prevent Second Impact Syndrome, a condition in which a person experiences a second brain injury shortly after the first. Second Impact Syndrome can have devastating effects, including death.
"For every one concussion that you see we identified, there were six concussions that were not seen and were not being reported."
The results took him by surprise. Mr King tested more than 100 Wellington premier rugby and league players over three years using what's called a saccadic reading test, which he calls his number-one tool. Players do a baseline reading pre-season and again after the games.
“For decades, optometrists have used the King-Devick test to aid in the diagnosis of ocular motor dysfunction and a need for vision therapy,” says Marc Taub, OD, MS, FAAO, FCOVD, chief of vision therapy and rehabilitation and supervisor of the residency program in pediatrics and vision therapy at Southern College of Optometry. “It is reliable and easy to perform in patients of any age or cognitive ability.
“It’s about that Jell-O within that cranium,” says Dennis Cardone, an associate professor of orthopedic surgery at Langone Medical Center, and co-director of NYU’s Concussion Center. “How it moves around, and how it collides with the cranium itself.” Because a significant proportion of our brains is used to process visual information, many of the symptoms that can be used to diagnose concussions affect vision. Cardone uses a screening test called the King-Devick test, which was developed in 1976 to measure deficiencies in eye movement during reading.
The King-Devick Test is one method Clugston and his team have used since 2011. The test is a two-minute challenge that requires an athlete to read single-digit numbers displayed on cards or on an iPad. UF collects baseline data for the King-Devick Test as with all of its concussion tests, and if an athlete is suspected of suffering head trauma, he or she is re-tested. If the time needed to complete the test is any longer than their baseline result, the athlete is removed from play and further evaluated.
UF and the University of Pennsylvania were the first schools to implement the King-Devick Test as part of their concussion management programs. “That’s something we feel is important to add in to the other concussions tests that we already do,’’ Clugston said. “It’s the only one of the simple tests that really looks at vision, and vision is a big component of the brain.”
Dr. Kurt Miceli, Medical Director of Bancroft, a neurological rehabilitation facility says it could prevent more injuries. “I’ve seen numbers one and a half million up to three million concussions a year, tremendous amounts of folks who are undergoing these concussions and the concern is to really have our kids or whoever it is not to suffer a second one.”
Video: A simple test can be done after a head injury and is a reliable way to quickly diagnose a concussion.
The simple assessment, which doesn't require medical knowledge to conduct or evaluate, may be especially useful in the youth sports arena where trainers and team physicians are few and far between. The rapid, low-tech evaluation may also help keep injured athletes from re-entering play and risking second impact syndrome, which can be fatal.
“We want to make sure that those communities that have very few resources for sideline detection can get some,” Robert said. “If we can do that for our schools — have a quick way to perform the test and have it interface seamlessly with a report to this office and perfect permanent record — then we have really made a contribution to detection and aftercare of our students.”
Don't Blink. The King-Devick Test: A Rapid, Sideline Visual Assessment Tool to Assist in Detection of Concussion
Take Home Message: The King-Devick test is a quick and reliable method to assess vision, eye movements, language function, and attention. An athlete with a concussion tends to complete the test slower than his/her preseason assessment while other athletes improve over time.
"In the youth leagues in particular, when there may not be doctors or athletic trainers on the sidelines when a kid gets hit, this enables parents with proper training to participate in the preliminary assessment of concussions," said study author Dr. Steven Galetta, a researcher at New York University Langone Concussion Center. "It's so affordable and easy to administer that any coach or parent could use it to determine when an injured child can return to the game and when they need to sit out."
Watch Jenna Lee talk about Head Injury with Laura Balcer, MD, from NYU.
"A vision test absolutely needs to be added," Dr Galetta told Medscape Medical News. "This one has been the most rigorously tested on the sidelines, and it's easy to administer by parents and others."
Overall, the King-Devick test had by far the greatest accuracy and lowest risk of false positives. The upshot, Dr. Galetta believes, is that parents and coaches “should absolutely consider” familiarizing themselves with the King-Devick test and administering it to young athletes before the season starts, then having those baseline numbers and the test itself handy on the sidelines.
Simple as it may sound, the K-D test actually does a better job of detecting concussions (with a 92 percent success rate) than two better-known methods: a "timed tandem gait test" similar to a walk-the-line test (87 percent), and a cognitive test known as the Standardized Assessment of Concussion (68 percent).
While the success rate of the King-Devick test is impressive, Balcer emphasized to HuffPost that if possible, parents should have their child perform all three of the above-mentioned concussion tests when he or she takes a hard hit. The reason could not be more clear. In tandem, the three tests can detect concussions at a rate that is truly hard to believe -- 100 percent.
“Given that concussions may cause devastating short and long-term cognitive effects, tools like vision testing that can objectively diagnose a concussion are critical,” says Laura Balcer, MD, co-author of the study.
“Our findings in children and collegiate athletes show how a simple vision test can aid in diagnosis of concussion at all levels of sport,” says Dr. Galetta, who is also a professor of ophthalmology at NYU Langone. “Adding the King-Devick test to the sideline assessment of student athletes following a head injury can eliminate the guesswork for coaches and parents when deciding whether or not a student should return to play.”

Dr. Patrick Kersey, Medical Director for USA Football, couldn't have been more impressed with the implementation process and overall results. "The implementation process was a total breeze," Kersey said. "Very quick and easy to understand and administer, and can be done in almost any environment - optimal for the sports world."
"The actual science behind it and it being a potential valuable tool that fills a much needed void in the sideline management and evaluation of head injuries was my initial attraction," Kersey stated. "This test can provide some near immediate and important information to the medical provider, athlete, and coaches about head injuries and help answer the challenging question of 'does he/she have a concussion' and 'is it safe for them to return to play?'"
Kersey also pointed out the King-Devick Test would complement some of the more popular concussion tools that many organizations are already using, such as ImPACT.

"Studies have indicated that the King-Devick test is an effective tool for the real-time evaluation of concussion because it looks at rapid eye movement and attention, both of which are affected by concussions," said Dr. David Dodick, a neurosurgeon and the director of the Mayo Clinic's concussion program in Phoenix.
"It has now emerged as a gold standard, I think, for sideline diagnosis for concussions," Dodick said. "So it's only a matter of time, I believe, once the word gets out, where there's going to have to be a very good reason for them not to use it."
“Studies have indicated that the King-Devick test is an effective tool for the real-time evaluation of concussion because it looks at rapid eye movement and attention - both are affected by concussions,” says David Dodick, M.D., Mayo Clinic neurologist and director of Mayo Clinic’s concussion program.
Tests administered on the sidelines, such as the King-Devick and the Standardized Assessment of Concussions (SAC), require athletes to quickly read numbers or words, or to recall words. Athletes must equal or better their previous baseline test score in a set amount of time to get back into a game — and that is if they are otherwise asymptomatic. "Kids are still not honest. They want to work through it," Herceg said.
Injury liaisons such as Shaman do not need medical training to perform a series of simple assessments to check if a player may be suffering a concussion, Schmidt said. Each injury liaison performs a King-Devick test, a two-minute test conducted on the sidelines that requires a player to read single digit numbers displayed on cards, to check to see if there are any symptoms of head injuries.
“More than 50 percent of brain pathways are responsible for controlling eye movement, so injuries to the brain almost universally affect eye movement,” said Dr. David Dodick of the Mayo Clinic, who is also the Director of the Sport Neurology and Concussion Program.
Chasan’s team has provided the league with the King-Devick Test, a reading assessment tool that they’ve taught the coaches to use. Essentially, the King-Devick tool allows the coaches to compare a player’s typical brain function – as each player is baseline-tested before the season – with the player’s function directly after a suspected concussion.

Some surveys suggest there are 10-times as many concussions that are undetected than are detected. Along a similar line, Doug King, MD, and colleagues, wrote a recent paper showing that in rugby players undetected concussions are quite common. He routinely tested his rugby players with the King-Devick test and found that undetected concussions were three to four times more common compared to detected concussions.
Dr. Leong called a recent article published in The Lancet Neurology a must-read. "It highlights the important role of optometry, saying that vision-based testing is vital in managing all forms of traumatic brain injury (TBI) and provides a sensitive approach for sideline or post-injury concussion screening."
Mary Medina, the school’s head athletic trainer gave him the concussion standard ‘King-Devick’ test. “That is a short 32 second test where they read numbers and Oscar was off by a couple seconds,” said Medina. The test measured his ability to think and respond to a series of questions that he’d already taken in the past. Since he already knew the answers, he shouldn’t have had any difficulty; but that wasn’t the case. “We pulled him!” said Medina.

The King-Devick is a simple test that can be administered on the sidelines in less than two minutes, explains Troy Buchanan Principal Dr. Jerry Raines “It’s a very fast, two minute, sideline examination. We’re making database decisions instead of subjective decisions. In the past it was ‘What’s today? What did you have first hour?’ Those are more subjective. We always subscribe to ‘When in doubt, sit ‘em out,’ but this allows us to have data behind that decision. Ultimately it’s for the safety of our kids.”
Concussion Head Games - Why brain research and baseline testing should inspire a public cry for action
Specifically, we are recommending that the King-DevickTest be performed by all Doctors who work with children, especially Doctors of Optometry to establish baseline for all patients, especially for young children and teens who are at higher risk.
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.

"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."

"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.

Many sports medicine professionals suggest that those coaches who do not have immediate access to an athletic trainer use easy and reliable screening tools. One of the most effective screening tools is the King-Devick test. Personally, I recommend every high school and youth coach to use this screening tool. It is very easy to learn and does not require a medical professional to administer. The King-Devick test can be easily implemented into an existing concussion management protocol.

The NYU Cover Story, notes: “Drs. Galetta and Balcer believe the King-Devick test works because at least 50 percent of the brain’s circuits are involved in vision. Thus the test can pick up deficiencies occurring across a wide range of neurological geography.
“Right now, these tests — King-Devick, SCAT2, balance, computerized assessment — are considered the standard of care, or the best procedure, for diagnosing concussions,” head Notre Dame University Physician Dr. Jim Moriarty said. “The key for us is if you’re a physician on the sidelines, you’d like to know the tests you’re running are reliable. There are symptoms that confirm concussions, but most people don’t have that. Most people have the lesser symptoms which cause you to have doubts whether you’re making the right choice or not.”
