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.”

Through several professional roles in education, Jennifer Thunberg always has maintained a strong connection with athletics and provided leadership – locally, within her league and sport community, and currently at the statewide level serving on the Representative Council of the Michigan High School Athletic Association.

To recognize her vast an ongoing contributions, Thunberg has been named the 39th recipient of the MHSAA’s Women In Sports Leadership Award.

Each year, the Representative Council considers the achievements of women coaches, officials and athletic administrators affiliated with the MHSAA who show exemplary leadership capabilities and positive contributions to athletics. Thunberg will receive her award during the Division 1 Girls Basketball Final, March 22 at the Breslin Student Events Center in East Lansing.

A standout herself as a three-sport athlete at Bay City Central and then volleyball player at Saginaw Valley State University, Thunberg began her coaching career at Central in 1997 and teaching career there in 2001. After coaching the volleyball junior varsity two seasons while still playing collegiately, she led the varsity to a 249-201-43 record over 10 seasons before moving on to Pinconning High School, where she served as athletic director from 2008-14.

Thunberg returned to Central as an assistant principal and became the school’s athletic director in 2017. She remained in that position until becoming principal at Freeland Middle School two years ago.

“A lot of the women who are on that (WISL Award) list are women who have been mentors of mine – who I have worked very closely with – and to be included in that group of women, I’m humbled and honored,” Thunberg said. “Jean LaClair (Bronson, 2015) has been a mentor of mine since I began my coaching career, and I can’t say enough about her. (There are many) between the volleyball world and athletic director world, and I’m just honored to be part of it.”

During her time as Bay City Central’s volleyball coach, Thunberg also served as president of the Michigan Interscholastic Volleyball Coaches Association (MIVCA) from 2005-08, and was instrumental in the creation of the annual Miss Volleyball Award honoring the state’s top high school senior.

As Pinconning and later Central’s athletic director, Thunberg hosted several MHSAA Tournament events and Coaches Advancement Program sessions. She also has served on MHSAA committees for volleyball rules, site selection, Scholar-Athlete Award selection and Women In Sports Leadership Conference planning.

She was one of only two female athletic directors in the Saginaw Valley League when she took that position at Central, and she served as the league’s executive director during the 2022-23 school year. The Michigan Interscholastic Athletic Administrators Association (MIAAA) named her its Region 8 Athletic Director of the Year in 2022.

Thunberg also served on the board for the Michigan Association of Secondary School Principals from 2015-21. She was appointed to the MHSAA’s Representative Council at its 2023-24 Fall Meeting and is serving a two-year term.

“At every stage of her educational career, Jennifer Thunberg has taken on a leadership role, and her vision and dedication to students is admired by her athletic and administrative communities across the state,” MHSAA Executive Director Mark Uyl said. “She is a strong believer in the power of athletics to help drive a student’s all-around education, and we are thankful to have her voice representing school sports.”  

A 1996 graduate of Bay City Central, Thunberg played basketball, volleyball and softball for the Wolves. At SVSU, she earned a bachelor’s degree in secondary education and master’s in educational leadership, and she remains among the volleyball program’s all-time leaders in single-season aces.

Thunberg earned her certified athletic administrator designation from the National Interscholastic Athletic Administrators Association (NIAAA) in 2010, and her certified master athletic administrator designation in 2014.

In addition to leading a school and serving on the MHSAA’s Council, she’s also currently serving as president of the Bay County Sports Hall of Fame.

“I was student council president in high school, National Honor Society vice president, and whatever group I got involved in … I just liked to be involved in those organizations,” Thunberg said of taking on leadership roles. “And every single one of those organizations improved and helped me more than I’ve helped the organization. They’ve taught me things, helped me get to know more people – helped me become who I am today.”

Her husband Todd Thunberg is a teacher and Bay City Central’s girls basketball coach, and they have two daughters, 13-year-old Taylor and 11-year-old Rylee.

The first Women In Sports Leadership Award was presented in 1990.
