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.

Early Results

May 17, 2016

On May 3 we released a preliminary summation of results of winter season concussions reported by Michigan High School Athletic Association member schools. It was reported that 48 percent of the concussions reported were to female athletes, who make up only 38 percent of all winter season participants.

We will be digging deeper into the reports and providing a more comprehensive summary for all three seasons – fall, winter and spring; but we already see one suspected theme is being confirmed: more concussions reported for girls than for boys.

Even though girls’ participation in basketball is 36 percent lower than boys in MHSAA member high schools, there were 88 percent more concussions reported for girls than boys in that sport this past season.

We hope that researchers will step forward to inquire into the physiological, psychological, social and other reasons for the significant disparity in concussions reported by males and females; and perhaps they will be able to suggest what administrators, coaches, rule-makers and others might do in response to that research.

We expect that other themes suggested by the data from this first-year reporting requirement and then year-over-year comparisons will create interest in other research, all of which will help make school sports an even healthier experience for boys and girls than it already is.
