Helmets are designed to prevent and decrease severity of TBI and they do. End of story.
I am glad that you can give me the numbers.
Lets compare the number of deaths and incapacitating head injuries for the years 1930 -1940 vs. 1980-1990.
And since you obviously have the numbers, please include broken necks, broken backs and incapacitating injuries.
My point is/was that although wearing a helmet is a good thing, the benefits from doing so and the penalties for not doing so are not the equivalent of Russian Roulette with only 3 empty chambers as some would insist to be the case.
Every year the the United States Pony Club issues an Accident Report. USPC began requiring ASTM/SEI approved helmets in 1990. From 1982 to 1989 the percentage of head injuries was 24.2%. In 1992 the percentage of head injuries was 14.3%.
A ten percent drop in head injuries three years is enough for me.
this cannot be a true story, but one of those fact situations you give a class in college to those working on their equestrian degrees...point out all the things done wrong in this situation by both parties...
