The specific claim:
"This graphic depicts the probability of AIS 2 Injury (BrIC) at a 6.2 M/S 45° angled impact, comparing standard foam helmets and the same helmets with WaveCel inserts."
And the probability given is:
Standard foam: 69%
Wavecel 1%
This seems a rather disingenuous claim in that it is not claiming to prevent 99% of concussions, only at at their specific and arbitrary tested parameters it
Fairly obviously like any other helmet it will be completely useless in many scenarios.
They have a study which says
http://trek.scene7.com/is/content/TrekB ... esting.pdf
"In vertical drop tests at 4.8 m/s onto a 30° anvil, their cellular structure
reduced linear acceleration by 14%, rotational acceleration by 34%,
and neck loading by up to 32% compared to a traditional EPS bicycle
helmet. In combination, these findings suggest that elastic suspension of
a properly designed cellular structure has the potential to reduce ro-
tational acceleration and brain injury risk. These impact performance
gains of CELL group helmets came at a cost of a 36% increase in helmet
weight compared to CONTROL group helmets. Since helmet weight is
critical for consumer adoption, integration of CELL technology into a
consumer product should focus on minimizing the associated weight
increase. "
'Heavier helmet more effective' doesn't seem that surprising to me.....
