philcrisp said:Second study, did you notice that the authors worked for a goverment agency? I'm not that familiar with NZ bureaucracy, is the LTSA responsible for the helmet law? I note their findings but the LTSA have since published figures for bicycle use in NZ showing a long term decline. Official numbers here http://cycle-helmets.com/nz-ltsa-2006.pdf
philcrisp said:In respect of Australia, wasn't that the point? The helmet laws are claimed to have coincided with a reduction in cycling which on its own should have been expected to have produced a reduction in head injuries assuming a constant ksi per km rate. In addition the laws were introduced in tandem with measures that had been shown to be effective at reducing collisions in all road users in other jurisdictions, the helmet law being the only novelty. Therefore how can an increased proportion of cyclists wearing helmets be said to be effective if there casualty rate does not decline faster than other groups?

When I was 16 I crashed during a descent which I rode at least once a week due to a nice combo of copious rain, poor surface and a nice dash of oil for luck. Looked down at my comp to check my speed (about 55km/h) and that little lapse of concentration was all it took for me to go down. Rider error yes, I wouldn't have crashed if I'd payed proper attention but everyone makes mistakes (stage 5 Veulta is a nice example haha)
I must have slid headfirst into the gutter because my 6month old $150 giro helmet was split in two and there must have been a bit of bouncing along the road at some point from the damage. A passing motorist found me unconcious and called the ambulance. Hospital for 2 weeks, can't remember the four months post crash.
I'm 19 now and at uni - I'm still on medication to control headaches and excessive fatigue when concentrating, I have to use the disability service there to manage due to very poor short term memory, I sit my exams in a room by myself so I can focus... but I'm still able to do well at uni, train and race pretty well normally and enjoy life. Would I be able to if I wasn't wearing a helmet? Hard to say for sure but I'm fairly certain that it would have been better than a little bit of cotton over my scalp?
IMHO there isn't really a valid reason for not wearing one - weight, airflow, price etc are negligable when you think whats potentially at stake
Sweet thats my lil rant out of the way!
elapid said:This paper still does not look at head injuries as an individual group. It just looks at injuries and categorizes them according to their severity, regardless of whether it is head, limb or torso. As said previously, a helmet is not going to prevent or minimize the risk of non-head injuries.
elapid said:There is no methods or results to this study. Just a report of their findings. While I acknowledge that a helmet will not prevent head and facial injuries, particularly high speed and rotational injuries, it may well minimize the risk of direct trauma, particularly to the temporal region. I would like to know the speed at which this test was done and compare this to typical speeds at which someone would fall of their bike and hit their head.
elapid said:I wouldn't expect to see significant difference when only 11% of cyclists with head injuries were wearing a helmet. This is most likely a type II statistical error because of low statistical power: 37 cyclists wearing helmets v 300 not wearing helmets. What is interesting is the proportion of head injuries in other pursuits: leisure time (36%), housework (28%), business (15%) and non-bicycle traffic accidents (11%). May be we should be wearing helmets all the time!
elapid said:Does this mean that you do not trust the report because it was a government agency published the findings?
elapid said:There is no statistical association. The authors have just stated that there is a decline but made no effort to statistically associate the two events. There may have also been a reduction in lolly consumption - does this mean that less kids are riding bikes to their local milk bar to buy lollies? The two events may be related or could be independent, but this is unknown until some sort of statistical analysis is performed. Furthermore, as other studies have shown including one mentioned in your post, many bike accidents involving head injuries are not associated with motor vehicles. The introduction and enforcement of speed and drink-driving laws may affect bike-vehicular head trauma but it will not affect the rate of non-vehicular associated head trauma.
elapid said:I can also personally understand why compulsory helmet use was introduced in Australia. The TAC (at least in Victoria) are financially responsible for the medical bills of any on-road trauma, including to cyclists. Why not try to reduce their financial burden by improving the safety of cyclists, even if that means there are less cyclists on the road (which could also be a reflection of societal issues such as the separation of communities from work places, etc, etc)?

Local high school hockey star slipped in the shower, hit head and died - was not wearing his helmet.
National football legend fell off one story roof whilst blowing leaves out of gutters, hit head and died - was not wearing his helmet.
Local teacher had light fixture fall on his head during class - no helmet - died.
Local school bus driver stopped at KwikMart for coffee, got struck by car and head hit pave as just to enter store - no helmet - died.
Local kid fell out of tree hit head - no helmet - died.
Local running star was trail running and fell and hit head on rock- no helmet - died.
Two different circumstances in one month where hikers at park fell off trail and hit head and died.
Little leaguer hit ball back at pitcher(his dad!) in practice - dad hit in the head and died.
Stairs, ladders, balconies, roofs, roads, wet conditions, icy conditions, snowy conditions, baseball, basketball, cheerleading, auto driving,under trees, under lights, while hunting ......
Perhaps the poll should be, "Do you wear a helmet 24/7?"
Steampunk said:Quick question: what is the difference between the approved but inexpensive helmets found everywhere for ~ $20 and the helmets at my LBS that cost up to $300?
Are there significant benefits in terms of 1. safety, or 2. performance (racing, etc.)?
elapid said:Good question. This is from an archived thread from BikeForums:
"The price difference is primarily engineering cost. They all have to meet the same safety standards. Engineering a helmet that is lighter and cooler (more vents and vents shaped to produce greater laminar flow) while still meeting the same safety standards is much harder, requires much more time, much more testing and redesign to finally get it right."
The thread then continues into a bit of a political debate where it states that in the USA helmets are not tested by authorities to ensure that they conform to the CPSC safety standards, as they are in Australia, but rather rely on the Chinese manufacturers of most bicycle helmets to manufacture helmets according to these safety standards. The Snell Foundation does independently test helmets in the USA and hence a Snell sticker does imply a certain level of confidence in the product. Apparently, the only helmet manufacturer that allows Snell testing in the USA is Specialized. See http://www.smf.org/stds.html for more information.
mofiki said:I only wear a helmet when participating in group events where helmets are required. I have little faith that these cheezy foam structures actually do much at all to help avoid major injury in a crash however as a "skid lid" it probably would be effective. I also feel the manufacturers put alot of mis-information about there effectiveness out there and most fall for it. I look at the costs of the helmets most desired by bikers and think to myself what a ripoff. Prices exceeding well above $100 is BS. I think that's why most of my friends I ride with don't wear them either. It really is insulting not to mention really ****es me off that any products targeted to bikers are priced so far out of line. It's not that I can't afford it, I can easily afford it, I'm just not that stupid. I say let the manufacturers keep it. But, that's getting into another topic so I'll stop there.

Giro has saved my life and I dont have to eat with a straw so I am down with the helmet.
biker jk said:I certainly do wear a helmet, always. My wife recentylu went over the bars and landed hard on the road and would have sustained a serious head injury but for her helmet.
It's just plain irrational not to wear a helmet when cycling. I'm yet to hear an argument against wearing a helmet that's based on common sense.
Bustedknuckle said:'May' help, will never hurt. I think the question is not helmet or not but helmet LAWS or not. No laws please, it's a 'nanny law', protecting you from yourself.
If they are going to make it illegal to ride w/o one, they had better start with motorcyclists(no helmet law here for them).
