there are no convincing day that in the literature that showed any particular helmut been better than any other in preventing sports concussion. given the many variables that exist in the athletic population and the exposure to index, it is perform a to exp tiral. -- trial. a study of concussion is limited by the ambiguity of the outcome being studied. there are no public data sustaining other protective equipment prevent concussions. with sports such as soccer, protective head gear is the exception, i've seen the use of headgear altering playing style in the wrong direction. as the new-found sense of protection encourages more physically aggressive play. i am asked about the claims parents hear about the equipment they should buy. no piece of equipment can significantly reduce concussions from occurring. concussion prevention is much more about teaching proper technique, planned by the rules, and editing the overall dissident acts. the harm i see caused by products that can to prevent concussion is far more than that financial harm of paying more for something that is not likely to w
