Staying Ahead on Head Safety

July 6, 2015

Three stacks of concussion-related material offered precious little space on MHSAA Executive Director Jack Roberts’ desk, and perhaps consumed even more room in his head as he tried to wrap his mind around the seemingly daily “latest and greatest” documents outlining signs, detection and return-to-play elements involving head trauma.

Without a doubt, the scene is quite similar on any given day in the offices of his cohorts across the country as school sports leaders are faced with the daunting, dizzying task of devising plans to address concerns aimed at the health of their games.

Lawmakers, rules makers, medical experts and the court of public opinion all want the same thing for student-athletes: a reduction in the chances of head-related injuries. And they all are perfectly willing to offer instant fixes to those in charge.

They often expect those in Roberts’ position to analyze, digest and create action plans as soon as possible without considering the research and resources it will take to get there.

“All parties involved want the same thing. We all want to provide the safest environment for educational athletics through protocols and practices that will offer the most minimal risk of injury,” Roberts said. “But, this can’t be accomplished through unfunded mandates which would stifle the already struggling athletic budgets in many schools.

“Changes have to occur through training and education, orchestrated through state offices and executed locally. And, it takes time to research the best and most effective means. There is so much information, and so many devices in the field today that those in athletic leadership roles almost have to have a medical background as well.”

For instance, there are documents which list as few as five symptoms for concussions, and those listing as many as 15. There are sideline detection methods which purport to take 20 minutes and those which claim to determine concussions in 20 seconds. There are as many return-to-play protocols as there are state associations.

Increasingly, state high school associations are seeking opinions and expertise from local medical personnel. In March, in one of many such meetings, Roberts and other MHSAA staff welcomed several from the Michigan Department of Health and Human Services to their office to discuss sideline detection methods and return-to-play issues.

“There are two areas that concerned us most,” Roberts said. “One, sideline detection of head injuries is inconsistent across the state in terms of both results and resources. Two, we need methods which generate immediate reports and permanent records.”

As the group which convened in March discussed the topic, potential hurdles and new perspectives on sideline management came to the forefront.

On the money and manpower front, who would be responsible for administering sideline tools? Most ideally they would need to be overseen by medical personnel rather than coaches or team managers.

From a perspective standpoint, an interesting view was volleyed out to the group: could sideline detection actually speed up a student’s return to play rather than slow it down? Current protocol prescribes that if competition continues while an athlete is withheld for an apparent concussion, that athlete may not be returned to competition that day but is subject to the return-to-play protocol. And, clearance may not be on the same date on which the athlete was removed from play. Only an M.D., D.O., Physician’s Assistant or Nurse Practitioner may clear the individual to return to activity. With immediate sideline detection, are parties more vulnerable should a student pass immediate tests, only to have undetected effects of the incident increase over time?

“The group shed a different light on the various scenarios, which was a primary purpose for the meeting,” Roberts said. “As one can see, there are so many variables to consider when attempting to determine the next plausible and practical steps toward minimizing and detecting head injuries.

“Further, we have to take into consideration practice sessions as well as competitions, and all sports, not just select sports.”

Adding to the challenge is simply the nature of athletics. Competitors at any level are just that: competitive. Often, students – or their parents – will attempt to hide symptoms or be reluctant to come forward with injuries, particularly head injuries which can’t be seen.

In more cases, perhaps the symptoms simply are not recognized, which is why education is paramount. 

First, association leaders have to tackle the due diligence of researching issues and potential solutions to situations currently threatening the well-being of scholastic sports. Considering that some 1,620,000 results are offered when “sideline concussion detection tools” is typed into a search engine, this is a laborious and continual chore.

Such information then needs to be packaged and presented to leaders at the local levels – athletic directors – to pass on to coaches, the individuals who have as much or more influence on students that perhaps any other adults, including parents in some cases.

This is why MHSAA rules meetings, Coaches Advancement Program sessions and other statewide forums continue to bang the drum on health and safety issues; to make sure the messages and procedures reach the student-athletes.

And, it’s why the MHSAA is asking coaches and ADs to be accountable in verifying that the plans in place are being carried out.


Less Could Mean Less

There are times when it’s good to say, “less means more,” but in the case of contact sports, practices and competitions, the idea is for less to mean less. As in less time for collisions to occur yielding fewer injures.

It’s early yet, and one year does not constitute a large sample size, but the MHSAA Football Practice Policy instituted last August could be one step toward reducing head injuries.

Beginning this past football season, the number of practices with helmets, shoulder pads and full pads were limited to start the season, and preseason “collision” sessions were limited to one per day. During the season, such practices were limited to two per week, while the length of practices was also regulated.

Dr. Steven Broglio of the University of Michigan Neurosport department is conducting a three-year study of the Ann Arbor Gabriel Richard football program with the assistance of Richelle Williams to determine the “Effects of Concussion and Sub-Concussion.” The study began in 2013, one year prior to the new MHSAA guidelines.

Research in 2013 showed approximately 650 “impacts” per player.  In 2014, the number dropped to approximately 500 impacts per player. Impacts are defined as greater than 10 gs of acceleration. Williams stated that a slap on the back is 4 g, coughing is 3.5 g.  On average, a helmet hit is 25-45 g.  Concussions usually happen (roughly) between 80-150g. 

An encoder is embedded into each football athlete’s helmet which monitors head impacts and exactly where the impact is located. Williams sits at each practice and game and through a pager identifies the player’s number and impact from a hit of 90g or more. 

They are also looking at those who do not sustain an impact concussion, but rather sustain multiple head impacts and whether those multiple head impacts lead up to brain changes (measured through EEG). 

The initial findings, as submitted by the study team, indicated two reasons why there were fewer overall impacts from 2013 to 2014:  

Primary reason:  The MHSAA adoption that became effective in August 2014 with new limitations that were placed on “collision practices” and conditions that full pads could not be worn until the fifth day of team practice.

Secondary reason:  Fewer players evaluated in 2014 than 2013. 


Fit for a King?

Editor’s Note: There are many sideline detection tools on the market, as a quick Google on the topic will reveal. The following, the King-Devick test, is among the highly recommended tests, summarized here simply to provide an idea of the types of systems available and how they operate. The following is from King-Devick’s website.

The King-Devick Test is an objective remove-from-play sideline concussion screening test that can be administered by parents and coaches in minutes. The King-Devick Test is an accurate and reliable method for identifying athletes with head trauma and has particular relevance to: Football, Hockey, Soccer, Basketball, Lacrosse, Rugby, Baseball, Softball and Other Collision Activities.

King-Devick Test is an easy-to-administer test which is given on the sidelines of sporting events to aid in the detection of concussions in athletes. King-Devick Test (K-D Test) can help to objectively determine whether players should be removed from games. As a result, King-Devick Test can help prevent the serious consequences of repetitive concussions resulting from an athlete returning to play after a head injury.

How King-Devick Test Works

Concussions are a complex type of brain injury that is not visible on routine scans of the brain, yet are detectable when important aspects of brain function are measured. King-Devick Test (K-D Test) is a two-minute test that requires an athlete to read single digit numbers displayed on cards or on an iPad. After suspected head trauma, the athlete is given the test and if the time needed to complete the test is any longer than the athlete’s baseline test time, the athlete should be removed from play and should be evaluated by a licensed professional.

Remove-From-Play vs. Return-To-Play

Both remove-from-play and return-to-play decisions are crucial in concussion recovery. It is critical to remove a concussed athlete from play in order to prevent further damage. It is also extremely important to keep the athlete from returning to play until they have made a full recovery. There are tools to assist in making both remove-from-play and return-to-play decisions.

King-Devick Test for Remove-From-Play Decisions

  • Quick, objective sideline testing
  • Measures impairments of speech, language and other correlates of suboptimal brain function
  • Instant screening feedback in minutes
  • Administered by parents, coaches, athletic trainers and medical professionals in remove-from-play decisions
  • Neurocognitive Testing for Return-To-Play Decisions
  • Computerized concussion evaluation system (in the computer lab)
  • Measures verbal and visual memory, processing speed and reaction
  • Tracks recovery of cognitive processes following concussion
  • Assists clinicians in making return-to-play decisions

WISL Honoree Thunberg Embraces Leadership Opportunities in Every Role

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.
