    post concussion helmet choice

    So I had an off and a resulting concussion. out for about 1 week.
    Dumbass me goes swimming another week later, does a cannon ball, and gets concussed AGAIN! so 2 in 3 weeks. Now I'm sitting on the couch for about 4 weeks now, and finally feeling better. So....

    I need a new helmet with the best protection for XC and the occasional beginner trails at downhill parks. No jumping.

    I was thinking something with a chin guard like the MET parachute and the old switchbacks, or maybe the Casco Viper.
    All seem like you have to go over seas to buy one.
    What is available here with MORE protection, at least the ears, cheecks and possible the chin/front face.
    Thanks

    Nothing will help with concussion, helmets just keep lacerations off your head and your brains inside your skull.

    Prevent, no.
    Help, yes.

    Agreed, shiggy. The purpose of any eps liner is to take energy out of an impact. Furthermore check out the new tech a new company has developed from concussion research...

    you may also want to look at the new MIPS helmets (POC has a MIPS version of their Trabec). iirc, i read somewhere that the brain experiences both linear and angular acceleration in most impacts (this makes sense---very few impacts involve a perfectly linear motion like a woodpecker pecking on a tree)

    i think the MIPS system is supposed to help reduce the angular component

    These are cool but still only see motorcycle helmets which aren't as safe for biking as helmets specifically designed for biking.

    I plan on letting them know this technology could help cyclist as well, and could be very profitable for them.

    I got a gnarly concussion last November and have gone to the MIPS helmet. Haven't had a hard crash yet with the new helmet but I would rather be riding with the latest technology than not. MIPS | Safest helmets in the market

    They also have a few youtube videos explaining the new technology if you are skeptical.

    Below is a list of available Mtb Helmets with the technology:

    As I understand it, the chin protection on a fullface isn't designed to do a thing for reducing concussion risk. It just protects your face from abrasion. The current helmet certifications focus on ensuring that helmets reduce skull fracture risk, they ignore concussion risk. Helmet technology is likely to improve dramatically in the coming years. For now, MIPS is the only concussion-specific feature out there.

    Thanks everyone for the info. I am almost ready to ride says the doctors.
    That means I am almost ready to go buy my next helmet as well.

    Keep those newer, higher tech helmet makes and models recommendations coming...

    post concussion helmet choice-anticoncussionhelmet.jpg

    This ridiculous image is eye-opening for me. Here is what it shows:

    two notable helmet experts prepared an analysis for us explaining what thickness a helmet would have to be if made with today's standard EPS foam to keep the g's below 100 in the drops included in the CPSC standard. (You might still be concussed at 100g but the odds are with you.)

    We mocked up a helmet with their parameters, and it came out looking like this:


    For me, this vividly illustrates the point that current-technology foam helmets don't and can't give effective protection against concussions. And also makes the point that our aesthetic preference for a slimmer helmet works against us when it comes to avoiding concussions.

    The image came from Bicycle Helmet Safety Institute, here.

    I understand the point they were trying to make. I read that site and not sure I buy everything they say. First the CPSC standard is ancient if you look at all the recent information that has been learned about head injuries.

    That article even mentions rotational energy "....upping the dreaded rotational energy to the head..." So the CPSC standard doesn't even take into account rotational energy, just a flat drop. Well when was the last time you crash with you body in a nice straight line and hit the ground, tree rock- whatever nice and perpendicular.

    Their take on MIPS is interesting reading, different from what many would expect.

    I know- that's why I take what they say with a grain of salt.

    First they talk about the head slips in a helmet anyway because it's not affixed tightly. Even with my basic physics classes 20 years ago, I understand that at the time of impact, the forces involved will change that.
    Take 2 pieces of paper in your hand and barely hold your hands together, move pretty easily, not push your hands together as hard as you can- they don't slip quit as easily.

    Then there's this gem:
    "There is even the question of how much you would want your helmet to slip. this study calculates risk factors for helmets that slip due to poor fit, and how much that increases the risk of head and facial injury. A MIPS helmet has a very small amount of slippage designed in."

    For people that are giving out advice about helmets, how they can't grasp the difference between my helmet slipping up off my forehead in a crash and allowing my head to hit the ground and a MIPS helmet that fits properly and allowing your head to rotate inside upon impact is beyond me. They're basicallt saying that a helmet flopping around on your head is the same as MIPS

    I'm sure that's true, but I'm not sure it proves that MIPS actually works. That website's point, as I understand it, is that there are lots of different slip planes at play--skull/scalp, head/helmet, helmet/ground. MIPS just adds another, and so far there is no empirical evidence that the MIPS slip plane provides any independent benefit.

    Responding more directly to your point, your point is that the head may not move in the helmet under impact, but is there a concrete reason to think that applies to head/helmet but not MIPS liner/helmet?
