[QUOTE="Bruce_ma gooshvili, post: 861755, member: 74121"] On further reading i see where you are coming from but there is not yet certainty. The following paper largely agrees with you: [URL]https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2987604/[/URL] But has this key paragraph in the section on rugby (which gives ammunition to either side of the argument) "[i]These findings, which indicate that rugby headgear does not appear to have a protective effect in concussion prevention, correspond to laboratory findings indicating that headgear are maximally compressed at impacts far below those likely to cause a concussion (71). Because they are unable to absorb additional force well below the threshold at which concussions occur, they would not be expected to have a major effect on the incidence of concussion. [b]However, this ceiling effect may be avoided in future headgear by methods such as modifying padding materials and increasing padding thickness (72)[/b][/i]" To suggest that modifications to rugby headgear could change the occurrence of concussion is more of Ann indictment of recent headgear rather than indictment of all headgear past or present. The paragraph suggests that sufficient padding would in theory prevent full compression of headgear at the levels of concussion causing impacts, but that this level of padding was not found in the head protectors covered. What is less clear is if that level of padding is achievable on a rugby head protector. Or would you have to go around with an unfeasibly large head protector that would make playing rugby impossible. I'd also agree that neck muscles may be a more important variable than headgear and, crucially for Pat Lambie, I'd say there probably isn't enough data available at the moment to allow him to make an informed decision - so it'd be a gamble with his health if he was presented with that medical advice (which is totally hypothetical). But that data will come in time with the amount of money and expertise being thrown at it. I'd say the jury is still out on whether a head protector can ever significantly reduce the susceptibility of concussion rather than assert strongly that it can, or that it cannot. [/QUOTE]
