Counting Concussions
December 9, 2016
Member high schools of the Michigan High School Athletic Association are in the second year of required reporting of concussions that occur during practices and contests in all levels of all sports served by the MHSAA. In year one there were 4,452 confirmed concussions reported. Less than two percent of almost 300,000 participants sustained a concussion, about half of which caused the student to be withheld from activity for between five and 15 days.
Not surprisingly, approximately half of the confirmed concussions were reported by Class A schools, which typically sponsor more sports and have larger squads than smaller schools. Class B schools provided almost 30 percent of the reports; Class C schools nearly 15 percent; and Class D schools less than six percent.
As we transition from fall to winter season, we can begin to make comparisons between years one and two of the mandated reporting. At this point, schools are reporting 1.6 percent fewer concussions this year than last.
This is surprising, because sideline personnel of member high schools have become more alert to the signs and symptoms of concussions. We anticipated that this would lead to more concussions being reported.
It is possible that these early stats are a sign of real progress in reducing head injuries in school sports. And, grabbing our attention most from the early reports is that 11-player football is reporting 3.9 percent fewer concussions as of Nov. 30, 2016 compared to the same week in 2015; and boys soccer is reporting 10.9 percent fewer than on the same date last year.
One Concussion Conclusion
August 25, 2017
After both the first and second years of collecting head injury reports from all Michigan High School Athletic Association member high schools for all practices and events in MHSAA sports, we cautioned people to refrain from making too many conclusions.
It’s too soon. We now have a baseline, but we will need several years before we can be certain that we’ve spotted trends or trouble spots.
Nevertheless, one observation screams out. Girls report two to three times the number of concussions that boys do. In basketball, soccer, and in softball compared to baseball, girls report two to three times as many concussions. That was true in year one; it remained true in year two.
It may be that girls sustain more concussions than boys, or that girls are more forthcoming in reporting than boys are, or both. In the past, researchers have published both conclusions.
In either case, it means we need to coach boys and girls differently, and we need to prepare coaches differently for boys and girls teams, as we are doing in the MHSAA Coaches Advancement Program.
