    How common are concussions from mtbing

    I read this article on theverge and it talked about helmets not being designed for preventing extreme impacts and not lighter ones that can cause concussions. Are concussions really that common for mountain biking? What do you guys think?

    It doesnt take much to get concussed.
    I would wager helmets are more for avoiding severe blood/fracture trauma. There isnt anything soft in them that would slow down your head from impact making concussion still a high likelyhood. MIPS are designed to keep moving after helmet hits the ground...interesting but super pricey for helmets at the moment.
    ((no you cant put a price on safety but people wont know or maybe cant afford $200 over a $50 helmet))

    In ten years of riding, I've concussed myself once when I went head first into a tree after sliding out during the landing of a small jump. Cracked my helmet and was dazed for a day while recovering my wits.
    Get out and ride even when you don't want to because ten minutes into the ride you'll be glad you did.

    Interesting article to add

    SENSELESS | Bicycling Magazine

    Bike helmets protect the scalp and skull by preventing lacerations and fractures. - I've crashed and I am thankful for my helmet

    Concussions are tough to deal with - in essence helmets do little to de-accelerate the head and the brain when it really wants to come to a sudden stop. The crush design of current bike helmets helps a little - but only a little. The forces involved are just too large for any kind of crash at speed.

    On the other hand I play it safe and always wear a helmet

    I gave myself a concussion a few years back. Took a hard fall due to diagonal roots on a steep downhill. It was January and the ground was frozen. The helmet didn't crack, I still use it as a spare (well, now its my backup spare).

    In retrospect it sounded pretty funny ( I don't remember any of it ). I kept asking my friend where we were. He kept trying to describe what trail and what part of the woods, but I was like " No, what park are we riding in? Where am I? " He explained, then we rode on and 30 seconds later I asked "Wait, where are we again?" So he volunteered to drive me the hour home and the whole way I asked "Why are you driving my truck? I have a concussion?!? OK, Wait a minute, why are you driving my truck?"

    Got a CT scan and everything was fine. Rested up and took it easy for awhile. Luckily I didn't whack it again anytime soon, they're finding that to be a real danger.

    I think concussions from MTBing are quite rare. However some people are much more prone to them than others.

    I've been punched in the head many times in my younger days and have never had a concussion. I've never been knocked out either. Other folks aren't so lucky, and concussions have finished their careers.

    I hope I've dodged a bullet and don't get boxers dementia when I get older. That would suck!

    I have had 3-4 concussions in 30 years of mtbing. All while wearing a helmet. Would have had greater injuries without it.

    Hit my helmeted head many more times without it resulting in concussions.

    I've had 2. The first was part of a crash that landed me in a 3 day coma. My cross country style helmet was cracked for and aft, left and right, all the way across like a plus all the way over the helmet. The front was abraded away since I landed and skidded on my face. I have no memory of the whole incident and am lucky to be alive and without brain damage. This happened in 1993.
    My doctor said I was more liable to get more concussions after such a brain injury. In 1996 I crashed again, downhill at about 30mph. I never lost consciousness, but was very groggy and with hindsight, it was clear I got another concussion.

    Since then, I never stopped riding, but I usually ride with a full face. Concussions are serious stuff and I've heard more recent studies suggest they are cumulative.

    2 concussions here. Both occurred when I was wearing a helmet. I figure they would been worse if I was not wearing one. I think that concussions are more frequently in mtb'ing than a lot of people want to believe.

    By comparison, 40+ years of martial art training, including a few years as a sparring partner for a Muay Thai fighter, only got me one concussion, but it was a doozie.
    It's nothing to take lightly, as all the evidence does point to cumulative, progressive damage from them as time goes by.

    My skull is triangular shaped because it has two sharp corners in the back as a result of childhood concussions. Back then I didn't wear a helmet, so if you can imagine full street speed going directly to a concrete curb was quite an oweee.

    I believe rocks are just as hard.

    What are the chances that there could be rocks in mtn biking?

    Like Drew, Ive been hit in the head a ton and taken my share of spills. Some people are more prone to concussions than others. I've never had one in spite of some pretty hard crashes (moto and mtb). I have friends who have had several and one friend who decided to give up motorcycle roadracing because of chronic concussions. Every time you get a concussion it does permanent damage and it seems from the latest research that this is cumulative.

    A polystyrene helmet is good for one very severe impact and that's it. Even though the shell may not look compromised the material which absorbs the impact (the liner...not the shell) is compromised. Helmets are cheap.....closed head injuries not so much!

    Rode motocross as a youth, age 6-14. Many crashes with helmets, no concussions. Been doing MTBing about 4 years now. Fewer crashes, all with helmets, no concussions. I've never had a helmet totally destroyed but I did have some that have been retired because they didn't look fine.

    If you see someone riding without a helmet they are really stupid. The likelihood of crashing can be debated, but the severity of head injury following a crash cannot.

    Fractured a vertebrae in my neck after I went OTB and hit a tree at least 20mph. The helmet cracked, but no concussion (although I'm sketchy about whether I hit the tree or the ground) despite no concussion. Man did I see stars right after!

    So as others have already mentioned, I think some are more prone to concussion than others.

    Best thing said in this thread so far.

    They help, they help a lot. I havn't had one on a bike yet, but a few racing motorcross and a few roadracing motorcycles. Long term effects, i'm not going into mine, but yes it can cause different problems.

    We have plenty new things to say about protection and what's inside your helmet. We're not trying to shamelessly self-promote our brand, so don't take this thread as marketing BS. HIP-TEC has created a new protective interior helmet technology, but we also want to raise awareness around current helmet standards and how they have stalled the progression of helmet protection. Most bike and ski helmets provide good protection against big impacts, at least in the range of 12 - 14 mph, what we are really trying to understand is how concerned are you about lower speed impacts and their effect on the brain. In full disclosure we are a company really trying to change the paradigm of head protection from just focusing on the larger impacts, to focusing on all of the different types of impacts that cause injuries. Itís going to get techy, but letís talk about it because itís important. You only have one brain.

    Hey Ray we don't want to spam. Thanks for calling us out though. That was kind of a junk fabricated paragraph. Admitted. We want to join this conversation and talk about ways to bring awareness to riders, that current helmet standards are not helping progress helmet technology. Most helmet companies make helmets to pass an old (40-year-old) standards test. It's pretty simple. Put a dense, hard foam inside a helmetÖdrop test it at a certified testing facility and if it absorbs the g's associated with maximum impact... Pass it...then produce it. This goes for that kids helmet you see in Wal-Mart or a high-end brain bucket you see in your local shop.

    People are going bigger, riders are going faster and new research is getting better at identifying how and why head injuries and concussions are happening at such an alarming rate. Low impact repeated blows or even a single impact at low speed can create 150 g's of force to the head. That's major concussion g force. Compare that to 170 gís which is the hardest hit recorded in football. You may think you just received a dazing hit from that small fall, but those small hits are really leading you down the path to something bad, possibly when you take that big hit. Make sense? A majority of helmets with dense hard foam inside are made to stop skull fractures, not concussions. Why not use a technology made to lessen and absorb the impact of low, medium and high impact blows? Demand more from helmet companies and ask questions about why they have not adapted their helmet technology to new research and tech on the market. Lot's to digest here, but we want this conversation to start now. There are a lot of great helmet companies doing a lot of great things, but we need to push protective technology to the next level now.

    I hope lots of different companies start getting serious about improving mtb helmet safety to better protect against concussions not just skull fractures. I hope riders look back 10 years from now and shake their heads at what stone age helmets we all are wearing now. None of this reflects well at all on the helmet industry over the past 20 years.

    MIPS has gotten most of the press I've seen about this, and there a few helmets out now with their stuff. I've never heard of Hip-tec before and their website is short on details at this point, but hopefully they'll be part of the solution too.

    One concussion here, but subsequent minor impacts weeks later keep reviving minor symptoms which is unsettling.

    I wasn't calling you out. I'm genuinely interested in the subject of head injuries. I've been around hundreds of them in my lifetime. Literally.

    We are hoping to be part of the solution as well. It is an interesting time in head protection as it seems that there has finally been enough acknowledgement from the media (mainly it seems through football) that there are larger, potentially more important issues than just fracturing your skull. MIPS has definitely taken a step in the right direction by getting information out there relative to how rotation impacts the brain during a fall. We are trying to take that a step further and increase the protective properties for both rotation and blunt impacts. We are really not trying to spam for pure sales purposes as there wonít be a HIP-TEC helmet available until late 2014 (Just the issue of being included as a part of the manufacturing of the helmet rather than an insert).
    Our main goal with the post on this forum is to gauge what athletes are thinking about head protection and hopefully to engage in some meaningful dialogue on how to push technology along in the same way that bike technology has been pushed along.

    Also, we are trying to get more info up on the website, but it is incredible how much time it seems to take.

    Happened to me once, woke up and found out that my bicycle was like 5-10 feet away.
    Helmet was all dirty up. I don't think I would have faired better if I was not wearing a helmet in a 7-10ft accidental drop.

    How common are concussions from mtbing

    I've had zero concussions in my life and have never been unconscious. Played soccer for 30 years... my head made contact with a lot of things- other players heads, an occasional goal post, elbows, blocked a lot of shots on goal (had ball imprints on my face among other exposed skin areas for a couple of days sometimes). Also hit my head on other things off the pitch when I was young and "indestructible" aka stoooopid (more than 100 stitches in my head).

    In ~13 years of riding I've damaged 5 (Bell) helmets and I am thankful that I was wearing one in each instance. I also agree that some are more prone to concussions than others.

    This one was the hardest hit and I ended up with a Type II+ AC joint separation in my right shoulder. Cracked the helmet nicely.

    I've read the statistics somewhere, but cycling is one of the most common ways to get a concussion. And, as mentioned above, helmets really aren't designed to prevent them. I've suffered two. One in the fall of 2011 while racing. Took three weeks to heal. I got a second in an accident working on a bike inmy garage this April. I'm still not back on a mountain bike yet. Head injuries are not o be taken lightly.

    As I mentioned earlier, take a look at the MIPS helmets. There are designed specifically to help reduce the chances of a concussion.

    My two cents here. A couple weeks ago I hit a 12 footer and bumped my head pretty good. Was wearing a cheaper full face (661 comp). I went to the hospital and they said it was just a mild concussion. Been totally fine. I would say they are " moderately common" but generally not "serious".

    Well... the doctor, who i believe is an EXPERT, said it wasn't serious, as there was no bleeding. Repeated concussions are indeed a problem, as are more severe concussions.

    With just about any older guy who has led an "active" life, a C-spine x-ray tends to look like a disaster zone. Even when the owner is symptom-free.

    Your wording on the first post sounds like you're saying concussions in general aren't serious. Considering the evidence is showing that the damage is cumulative, any concussion is serious.

    Although I can't speak of the Trabec Race MIPS, since my accident, I bought the Trabec which I do not think has MIPS, but I must say, it's an extremely comfortable helmet to wear, and since it offers more around-the-ear protection as well as more protection on the back of the head, I feel as safe as I can be when I'm out riding.

    I hope I never have to test this one as I did my $30 Specialized, but I feel confident that I have the best protection I can get, even though it does not have MIPS.

    No matter what helmet you get, a concussion is always possible- the price we pay doing the things we love...

    I understand what you're saying. I might have said the same thing a couple weeks after my mild concussion. But here I am 3 months later getting fairly debilitating concussion symptoms from minor head bumps. So even if you feel 100% now, my advice (and I'm not an expert) is to be extra careful for a while yet and don't assume you're good as new. (Which may be what TwoTone was getting at.)

    It may be 100% fine for you, but if its not a MIPS helmet, its not the best concussion protection you can get today.

    One the one hand, biking has saved his life because his strong heart kept him from having any permanent damage from a heart attack due to a genetic disorder. On the other hand, he has broken several bones from crashing(partly due to the genetic disorder).

    As a concussion specialist, I can tell you a few things.

    First, I know many things first hand because I have had a number of concussion from my football days and from cycling. I have had two while mountain biking in the past ten years. One rather benign and another that was more impactful where I lost consciousness and was in-and-out for the better part of an hour during a race.

    Second, there is no way to accurately predict or completely prevent concussions, short of not participating in cycling. The truth is, there are populations that appear more at risk, such as females, the younger athlete, and those with previous concussions, but these are just statistical pools.

    True, there is a relationship between forces, acceleration, and deceleration and its effect on the brain, however, at this time there is no predictive way to accurately suggest who will have a head injury from what force/event. The truth is that some athletes are concussed with the slightest of impact while being tackled in a football game whereas, another guy that gets lit up with a vicious hit will have no injury at all.

    There are statistics that show no reduction in head injuries with women soccer players wearing head gear when it comes to concussions. Statistically, there are more head injuries in contact sports (football and hockey). Given similar sports, such as soccer and basketball, women have a higher frequency of head injuries.

    There has been a lot of talk, clinically and in sports, of the true reasoning of wearing head gear protection. Mostly, helmets were developed to reduce the risk of skull fractures and serious injuries. Helmets have not yet been designed to statistically reduce the risk of concussions.

    With all of that being said, I would not ever risk going for a mountain bike ride without my helmet.
    There is a slough of research going on at the present time on head injuries. I believe that there will never be a way to completely prevent head injuries, however, advances in patient screening along with R&D by manufacturers and sporting entities will reduce the risk and frequency of them.

    My patients will tend to disagree with you. They believe that ALL concussions are serious!

    Might want to look at the MIPS and 6D helmets.

    They are gettin' there. One of those will no doubt be my next helmet purchase. I only recently bought a Giro Xen on closeout, just before I learned about the MIPS development. It's for sure a significant step up.

    What you see is engineering data, not medical research. There is a big difference between the two. A lot of things look good in a lab or in theory.

    I will repeat, helmets have not yet been designed to statistically reduce the risk of concussions.

    The challenge is not the engineering behind the helmet, but the variability and complexity of the human body. Although we have come to a generalized, worldly consensus as to what a concussion is, there are still many things that we don't completely understand about the brain and concussions. Again, there is not a threshold force that is found to elicit the chemical/metabolic cascade that we believe is a concussion. X amount of Newtons or Y degrees/second is not the same for each individual. One athlete may be concussed and suffer from Post Concussion Syndrome with a ball peen hammer while the next may not have any symptoms from a sledge hammer.

    As I mentioned before, I choose to ride with a helmet and maybe a person would have a bit more piece of mind with one of the aforementioned helmets. Unfortunately, their research is limited to computer models, not humans. No "real" research has been done, clinically speaking, with these helmets. I commend these companies for working on our problem, but as of right now, all I see is marketing data from them, not clinical research.

    I see. Kinda like cardiac stents, eh?

    I am certainly not a cardiologist, however, I do believe that the CLINICAL research now supports the use of stents, does it not?

    My point in the previous posts is that nothing that the helmet companies have done up to this point show that they decrease the frequency or severity of mild TBI's.

    I am not saying that there won't be evidence in the future, I am just telling you that nothing is proven as of to this point. Currently, there is only engineering lab data, which hasn't shown shown to carry over to clinical evidence, yet.

    I don't see how it ever will. As you said each individual is different, so how are you going to have a clinical trail showing the MIPS works? or any other improvement? You can't. You cant have group A wear non MIPS helmets and group B wearing MIPS helmet and then compare. Every crash is different and every individual is also.

    The best you can do is take the evidence that shows rotational energy is a large factor in concussions and produce a helmet to reduce those forces.

    I chose to think of it as crash test dummies for rating cars, I'm sure it takes varing force to break a bone in individuals, yet they have come up with a standard and measure to that.

    So until dis-proven, I'll gladly spend a little more on a MIPS helmet vs a non.

    Actually, you answered your own question.
    With a large enough sample size over a long enough period of time you will get your clinical answers.

    You have samples wearing the MIPS technology and another sample not wear this technology. You have on group, position, team, league etc. wearing this technology and compare it against the normative group or against previous statistics.

    I doubt that you will ever get this data from cycling for many reasons. These statistics will likely come from organized, team sports and be carried over to cycling. Some of the biggest challenges with mild TBI's are coming to a consensus as to what a concussion is, and how they are reported. We are seeing a huge uptick in the number of concussions over the past few years, however, it is likely due to the fact that we have better awareness of concussions and the reporting of concussions is much better.

    Another factor that is nearly impossible to account for is often brought up in football. If one wears a helmet where they feel protected against injury, they often put themselves in more vulnerable situations with the helmet that they would not have if sans helmet. This is an interesting thought when it comes to MIPS helmets. I wouldn't be surprised if concussion rates are actually higher while using them.

    I have been apart of many conversations, conferences, and presentations on just these topics. I still choose to wear a helmet and advise all to wear helmets when riding. The fact of the matter is, there is not proof that the MIPS helmet is any better than a $15 Bell helmet from Target.

    I would be. I think the idea that folks will start riding more recklessly because they're wearing a MIPS helmet instead of a non-MIPS helmet is silly. But I guess time will tell.

    But if more probative testing isn't forthcoming, it seems prudent to accept the less probative testing in the meantime. The engineering data is relevant, even if its not conclusive. Tobacco companies did the same quibbling for decades about lack of scientific proof, and gazillions died in the meantime. Maybe the extra $25 or $50 books spent on MIPS will one day be proven to have provided little or no benefit. But in a world of incomplete information, it seems to me like a reasonable investment. At a minimum, it all helps create a market for concussion-targeted designs.

    I suppose. It's a misleading statement whose accuracy relies on ambiguous meanings of "designed" and "statistically." Your posts add a lot to this thread and I appreciate your contribution, but this statement just seems inflammatory.

    Don't go all get your panties in wad, this stuff is not proven anything yet.
    Seems to me, this helmet will be proven to add a secondary wave bashing like whiplash to the brain. Then to boot, a pretty good number of scalp tears.
    If football players start using this on the field in games, at the pro level, then ring the bell.

    Who's got their panties in a wad, sounds like your reading comprehension is pretty poor if you took that from the quote.

    Doesn't really sound like you looked at too much of the data. I'd love to hear your hypothesis on the scalp tears.
