I guess my biggest concern is that the more expensive a helmet is, the less likely people are to throw them away when they've been compromised by a medium impact fall. I'm pretty sure mips wouldn't have saved me from a concussion, and my "old eps" definitely saved my life and my skull.
I should have clarified that i am only considering concussion reduction when looking for a helmet. The chances of having sever head trauma is very low and i do understand that helmets save you in those rare situations.
No good evidence that mouthguards and helmets ward off concussion — BMJ
This latest version of the Consensus Statement, which has the backing of the International Olympic Committee, FIFA, the International Equestrian Federation, and the International Rugby Board, was drawn up after a two day meeting in Zurich, Switzerland, in November last year.
Over the course of the two days, researchers from around the world were invited to present the latest findings on this common type of brain injury, which has the potential to cause long term neurological damage if not dealt with appropriately, particularly in sports, such as football, rugby, ice hockey, horse riding, skiing, and boxing, where the risk of concussion is high.
A panel of 32 international experts then distilled the research - details of which are published in the current Injury Prevention and Health Protection (IPHP) issue of the British Journal of Sports Medicine - until complete agreement was reached.
The Consensus has been designed to raise awareness of concussion among the public, so for the first time includes a concussion recognition tool (CRT).
And it clarifies the definition of concussion to emphasise that a player does not have to lose consciousness before being considered concussed and therefore removed from play. Symptoms of concussion can range from headache and memory loss to irritability, slowed reaction times, and sleep disturbance, it says.
It contains a new focus on the assessment and management of concussion in kids, who should not be returned to play the same day and who may require longer to heal than adults, it says.
And it provides a useful Q&A, a handy pocket symptom checker and assessment tool, as well as advice on medico-legal considerations and injury prevention.
It makes clear that mouthguards and helmets have a role in minimising injuries and are to be recommended, but emphasises: “There is no good clinical evidence that currently available protective equipment will prevent concussion.”
I think this is the actual paper but i haven't read the whole thing yet, just the little section on helmets and it does say ski and snowboarding. Its on page 5.
