Last year he introduced to the club the King-Devick test, a screening that can help determine whether a player has suffered a concussive incident during the game.
A player does an initial test in the preseason to record a baseline score. The players are then tested after every game, and if anyone is three-seconds slower than his baseline score, he is deemed to have suffered a concussion. Because the test is calculated on an iPad, it can even be used during a game if a concussion is suspected.
Last year there were five concussions witnessed on the field, but another 17 were diagnosed through the King-Devick test (which is named after another King, not Doug).
Major League Lacrosse will become the first professional sports organization to mandate the King-Devick test -- an objective rapid sideline screening test of concussions that a growing body of studies show is an effective test for concussion -- as an additional sideline assessment tool.
The K-D Test serves as a “remove from play” test and is actually more suited to a sports role than one might think. Since players can only be on the sidelines for a few minutes between plays or drives, time is of the essence. The player has to be assessed immediately; continued play with head trauma can be increasingly dangerous. “We do know that if you put a kid back in with concussive symptoms, he’s at really high risk to get hit again,” says Dr. Gillian Hotz of the University of Miami’s Miller School of Medicine.
Unlike SCAT, the King-Devick test is also more straightforward for a physician to score. It is not only less subjective than SCAT, but also more informative. In fact, in trials for the test, many concussed athletes have passed SCAT but failed the King-Devick test.
“As a direct result of the findings using the King-Devick Test, the club has implemented a wider concussion awareness program to assist in identification and management of concussion for the upcoming season,” Dr. Doug King, the senior author of the study, said in a news release.
The advantage of the King-Devick is that it’s much more straightforward for an inexperienced physician or coach to grade than the SCAT-2, which relies on subjective analysis of symptoms and test results. Many concussed athletes in the team’s trials have passed the SCAT-2 exam but failed the King-Devick Test.
On August 24, 2012 the Dave Duerson Foundation announced that they will be equipping all Chicago Public High Schools with the King-Devick test for sideline screening. The Foundation, through individual and corporate sponsors, also announced plans to provide the test to schools in other major cities in the U.S.
Before the high school football season kicked off Friday night, Chicago public league teams were given concussion kits to help detect and treat injuries to players.
A foundation named after former Chicago Bear Dave Duerson, who committed suicide last year, donated 80 concussion kits on Friday to football programs at Chicago public high schools.
With the kickoff of Chicago’s high school football season tonight, The Dave Duerson Foundation has announced it will donate 80 concussion testing kits covering all Chicago Public Schools’ (CPS) high school football programs. The kits, known as the King-Devick Test, are an effective remove-from-play sideline test administered to student athletes by trained non-medical professionals when concussion-like symptoms occur or are suspected during a game.
Use of a rapid visual screening tool for the assessment of concussion in amateur rugby league: A pilot study
A prospective cohort study was conducted on two teams participating in an amateur rugby league. All players were tested for signs of concussion utilising the K-D test and players with longer times than their baseline scores undertook a further concussion assessment with the SCAT2.
The current study investigates the effect of sleep deprivation on the speed and accuracy of eye movements as measured by the King-Devick (K-D) test, a <1-minute test that involves rapid number naming.
Another sideline concussion indicator the NFL and others are evaluating is a quick visual exam called the King-Devick test. Originally developed to identify people with the reading disorder dyslexia, the two-minute test involves reciting a series of numbers from flash cards or displayed on an iPad screen.
The King-Devick test is a very accurate, simple and inexpensive way to quickly test for the presence of concussion — right on the sidelines. This is critical because sending an athlete back into action too quickly after a concussion is extremely dangerous.
The King-Devick method, a number reading test, was originally used to diagnose defects in micro-eye movement. Researchers at the University of Pennsylvania said the same test can be used to diagnose a brain injury, keeping young athletes from further damaging their growing minds.
“The King-Devick Test provides doctors, athletic trainers, coaches, and even parents, with an easy tool to determine if the athlete should be removed from play to prevent a second head injury, which we now know can have more serious complications if the brain has not yet healed from the first concussion,” says Haynes.
One day when a teenager falls off his scooter and slams his head into the ground, a parent will reach into the medicine cabinet and pull out a King-Devick Test to check whether their child suffered a concussion and needs to be treated by a doctor.
From the concussions of Eagles DeSean Jackson and Kevin Kolb to the tragic suicide of Penn football star Owen Thomas, Philly has been the epicenter of sports head-injury news. Now, two Penn researchers are poised to put a big dent in the problem
The King-Devick test is a simple and objective rapid sideline-screening test for concussions that can be administered by coaches, trainers, and parents in two minutes or less. Some sports medicine professionals have called the test “the missing link” in concussion safety protocols.
A simple, two-minute test given athletes on the sports sideline provides an accurate and reliable method for quick assessment of concussion in college athletes, according to a new study by researchers at the University of Pennsylvania and published online in the Journal of the Neurological Sciences.
Ralph Nader Calls For Mandatory Implementation of King-Devick Concussion Test in High School and Youth Sports
Ralph Nader announced today that his League of Fans organization is pushing for the King-Devick sideline concussion test to become mandatory in all sports from high school down to the youth sports level. The announcement came in conjunction with the release of the League of Fans’ fifth report from its Sports Manifesto, “Concussion Research Can’t Be Ignored.”
The King–Devick Test and Sports-Related Concussion: Study of a Rapid Visual Screening Tool in a Collegiate Cohort
This study of collegiate athletes provides initial evidence in support of the K–D test as a strong candidate rapid sideline visual screening tool for concussion. Data show worsening of scores following concussion, and ongoing follow-up in this study with additional concussion events and different athlete populations will further examine the effectiveness of the K–D test.
The King-Devick test allows us to asses the objective findings by examining an area of the brain that is impossible for the athletes to memorize or cheat on.
This rapid screening test provides an effective way to detect early signs of concussion, which can improve outcomes and hopefully prevent repetitive concussions
The screening -- known as the King-Devick test -- is superior to current sideline tests that can fail to assess a wide range of brain functions, according to the researchers at the University of Pennsylvania School of Medicine.
