Concussion Testing Pilots Kick Off Fall
August 4, 2015

The Michigan High School Athletic Association kicked off the 2015-16 school year Monday by hosting 70 member high schools for training in two pilot sideline concussion testing programs aimed at assisting in decision-making regarding the removal of athletes from activity after possible concussion events and record-keeping of those events beginning this fall.
Illinois-based King-Devick Test and Maryland-based XLNTbrain Sport each will be used to monitor approximately 10,000 Michigan high school student-athletes drawn from schools representing all four classes and a variety of regions statewide.
The pilot programs are part of a three-pronged advance by the MHSAA in concussion care this fall. In addition to becoming the first state association to offer pilot sideline concussion testing, the MHSAA will be the first to mandate record-keeping by member schools of all possible concussion events from detection to an athlete’s return to play. The requirement applies to both practices and events, all levels of all sports in grades 7 through 12.
The MHSAA also this fall is the first state association to provide all participants at every MHSAA member high school and junior high/middle school with insurance intended to pay accident medical expense benefits – covering deductibles and co-pays left unpaid by other policies – resulting from concussions sustained during MHSAA practices or competitions. There is no cost to either schools or families.
“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.”
The MHSAA asked schools at the end of this spring to volunteer for the pilot programs and then selected participants in order to guarantee a variety of schools based on enrollment and location. Schools are committed to involving at least two sports for each gender each season.
Schools participating in the XLNTbrain Sport pilot program are: Adrian, Adrian Madison, AuGres-Sims, Bay City Central, Bear Lake, Brethren, Belding, Birmingham Groves, Brighton, Chesaning, Corunna, Detroit Collegiate Prep, East Kentwood, Fennville, Fowlerville, Gibraltar Carlson, Grand Rapids Christian, Grandville, Greenville, Grosse Ile, Hamilton, Harrison Township L’Anse Creuse, Hazel Park, Kalamazoo Christian, Lansing Christian, Macomb L’Anse Creuse North, Owosso, Pewamo-Westphalia, Portland, Reese, Rochester Hills Lutheran Northwest, St. Clair Shores Lakeview, St. Johns, Stanton Central Montcalm, Vermontville Maple Valley, West Bloomfield and Wyoming Kelloggsville.
Schools participating in the King-Devick Test pilot are: Bay City Western, Benton Harbor, Buchanan, Calumet, Caro, Caseville, Detroit Cody, Detroit Martin Luther King, Fenton, Flint Kearsley, Frankenmuth, Fruitport, Garden City, Grand Ledge, Grand Rapids Northview, Lake Leelanau St. Mary, Lake Linden-Hubbell, Lincoln Alcona, Midland Bullock Creek, Montague, Muskegon, Niles, Pontiac Notre Dame Prep, Romeo, Saginaw Heritage, Scottville Mason County Central, Shelby, St. Charles, St. Joseph, Tawas, Vicksburg, Whitehall and Yale.
The King-Devick Test is a rapid eye movement screening evaluation that requires athletes to read single-digit numbers displayed on a tablet computer in order to detect impairments of eye movement, attention, language, concentration and other symptoms of abnormal brain function. The test has been validated in more than 50 recent peer reviewed articles published in elite medical journals and is associated with the Mayo Clinic.
The test is administered on the sidelines during evaluations for suspected head injuries, and the post-injury results are then compared to an athlete’s preseason baseline. Any worsening of performance (increased time and/or errors) suggests a concussion has occurred and the athlete should be “removed from play” for further evaluation.
“The first and most critical step in managing concussion in the youth athlete is to recognize when one has occurred – not always a simple task,” said Dr. David Dodick, professor of neurology and director of sports concussion services at the Mayo Clinic. “The King-Devick test helps take the guesswork and subjectivity out of the sideline evaluation in a rapid, accurate, and objective way.”
XLNTbrain Sport includes balance and web-based neuro-cognitive tests also used before the start of a season to create a baseline measurement of reaction time, attention, inhibition, impulsivity, memory, information processing efficiency and executive function. The test also assesses mood, anxiety, stress and emotionality.
After a possible head injury, a sideline assessment is done using a smartphone or tablet with those results then compared with the athlete’s baseline measurements. The program documents the severity of a concussion, provides a guide for on-the-field decision making regarding treatment and recovery time and can report results via email to parents, coaches, training staff and medical professionals.
Dr. Harry Kerasidis, who designed the XLNTbrain Sport software, presented at the Coalition for Concussion Treatment Summit at the United Nations building in 2014.
“We included an objective balance test that relies on smartphone accelerometer technology which is effective in the field during practice and game situations,” Kerasidis said. “Should a concussion injury be suspected, the system automatically generates a notification to parents and medical professionals and creates a recovery protocol and post-injury tracking so the right people can monitor the athlete’s progress. Then, the system assists medical professionals with the all-important return-to-learn and return-to-play clearance.”

Vander Klay's Dedication to Wyoming Schools Netted 400+ Wins, Trip to Breslin

WYOMING – Over the past 31 years, it was relatively easy to notice a boys basketball team coached by Thom Vander Klay.
Athletic and tough-nosed players who competed hard while playing an up-tempo offense and in-your-face defense were trademarks of his teams at Wyoming Park and Wyoming High School.
“In some ways, at Wyoming Park, and then Wyoming, our athletes have been very similar through those 31 years of varsity,” Vander Klay said.
“Some teams were more skilled and more athletic than others, but they were the same. We never had big kids. We’ve always had kind of gritty kids that would compete hard and play fast, and we had quite a few of them on every team. That bled into what we did.”
Vander Klay will retire from teaching after 40 years at the end of May, and his time as the longtime basketball coach will end as well.
“It’s been a struggle, and it’s hard because it’s my home,” Vander Klay said. “I live in Wyoming, my kids went to Wyoming and I went to Wyoming (Park). I’m the youngest of three and my older brother and sister were Vikings and that’s who I was. I was Wyoming, and I still am, so it was really difficult to say I was going to step away from things I really enjoyed doing.”
Vander Klay has been coaching for 41 years. He was the junior varsity coach at Wyoming Park before replacing Kelly McEwen in 1995.
When Wyoming Park and Wyoming Rogers merged in 2012, he became the head coach at the new Wyoming High School.
During his tenure, he went 424-274 as a varsity coach and won nine conference championships, six District titles and one Regional title. He also helped coach football and track & field.
“So many memories and so many kids, and you love those kids,” said Vander Klay, who coached his two sons, Brock and Chase. “When I think back to when I started, guys like Jack VerDuin, Ron Engels, Dick Locke, Frank Grimm and Kelly McEwen were great mentors that I had. I go back to those days and blink, and here we are 40 years later and I'm the old guy.”
Vander Klay’s best season came in 2004 at Wyoming Park, led by eventual Michigan State standout Drew Neitzel. The Vikings advanced to the Class B Semifinals, losing to Detroit Renaissance.
Vander Klay was named Class B Coach of the Year and enjoyed his time coaching Neitzel, the Mr. Basketball Award winner who is widely considered one of the best players in program history.
“Drew was so well-rounded,” Vander Klay said. “A great leader, great student, great attitude and just mentally tough and so skilled.
“Coaching him was more about trying to get all five guys on the same page, but those teams that Drew played on, we had good players other than him, too. It wasn't just him because we had other guys who stepped up – but he was the best player in the state.”
Jacob Underhill, Vander Klay’s longtime assistant and junior varsity coach, said Vander Klay has been more than just a mentor.
“He has been the blueprint for the teacher and coach I strive to be,” Underhill said. “He has always been incredibly gracious in sharing his knowledge of the game and his wisdom on how to lead young men. Every decision he makes is filtered through a single focus: doing what is best for the students and athletes of Wyoming.
“While his retirement marks the end of an era, his legacy is undeniable. Since the merger of Wyoming Park and Wyoming Rogers, he has been the heartbeat of the basketball program. He has had a profound impact on my professional career, and I cherish the time we’ve spent serving the community together.”
Underhill has witnessed firsthand the influence Vander Klay has had on former players with whom he has reconnected.
“It’s a true testament to his character,” Underhill said. “He is an exceptional human being who makes everyone around him better and ensures they recognize their own value.”
The 62-year-old Vander Klay is keeping his options open in terms of a return to coaching elsewhere.
“I’ll take some time off and maybe there is something else out there,” he said. “I'm wide open to anything, and maybe I’ll coach again and maybe not. We will see what the future holds.”
Two other longtime Grand Rapids-area coaches also stepped down after longstanding careers on the hardwood.
Unity Christian coach Scott Soodsma retired after 43 years on the sidelines. He won more than 800 games and three MHSAA Finals championships as a boys and girls coach. Soodsma coached his last game in the Division 2 Boys Basketball Final at Breslin Center. The Crusaders lost to Freeland, 42-32.
Sparta boys basketball coach Scott Berry also retired after 34 seasons. He won 245 games at Comstock Park and Sparta.
