Just come across this paper in the July issue of Accident
Analysis and Prevention. Curiously it concluded that more
wearing of better helmets is needed despite finding a 33%
mortality rate in non-helmeted cyclists but a 100%
mortality rate in the small sample of helmeted cyclists.
Sometimes I think I know how Copernicus must have felt.

you're probably right, but since it's a subscription site,
all we can see is the highly unelightening abstract.

You were right about small sample - there were only three!
Also, it says this:

"An important shortcoming in the current helmet standards is
that linear head acceleration is the only injury mechanism
being considered, while it has been demonstrated by several
investigators in the field that the occurrence of certain
head injuries is correlated with other mechanical parameters
rather than linear acceleration. Consequently, tolerance
criteria which relate the occurrence of all brain injuries
exclusively to translational head motions have been
criticised for a long time"

Which is I guess why it says more wearing of *better*
helmets is needed. Given the risk to cyclists (in this
country at least) I really don't think it is dangerous
enough to warrant any more special treatment than
walking. Training at school (we all learn the Green Cross
Code etc) and well thought out cycling infrastructure
should do the trick.

Skimming through the text - they don't claim that their
findings provide any evidence for the effectiveness of
helmets. They provide references supporting this stance at
the start of the article.

Interesting to see who sponsored the study:

KBC Banking and Insurance (Brussels, Belgium) and Wolvenberg
NV (Mechelen, Belgium).

No prizes for guessing why they're interested.

The authors give a long list of circumstances where helmets
provide very limited protection and question the
effectiveness of helmets in bicycle-car collisions. It's all
out in the open (as it should be) so I'm not alleging any
wrongdoing.

I suppose I could accidentally attach it to an email if
anyone wants a copy.

Mark.

ps to send an email to me, you may want to turn up the heat.

Hi Mark,

I am guessing your email given above won't work, so could
you get my real e-mail address from www.thebikezone.org and
e-mail a copy to me. It may help in a new article on helmets
I am putting together for my site.

Regards,

Howard.

It's on bikebiz, in the public news section (look for the

No, it's a different one. The new one from Aziz Sheikh is,
however, a masterpiece, proving as it does that helmets Save
Your Life even if worn vicariously (his reduction in head
injuries is double the increase in helmet use...).

Thanks Guy, I'm glad to see you have read my research
carefully :-) My version didn't have the numerical typo that
cyclehelmets.org inserted (it actually had a minor
grammatical typo, but the numbers were right).

Indeed. Must have made a change for CTC to receive an email
from you that wasn't about disc brakes, eh? ;-)

I was amused that a Francophone colleague was unable to
restrain himself from referring to "Jules et Jim"...

We were amused, too.

In 1962 :-p
