Concussions don’t have a particularly objective diagnosis or a very clean phase transition between “concussion” and “not concussion”, they are more so continuous with a soft floor, and they do get progressively worse with vague intensity of injury. It’s not really until your brain starts bleeding and such that there are clear diagnostic signs and there are definite but more vague long term effects from lesser concussions.
Reducing kinetic energy is exactly the kind of metric you can take in absence of any others.
- jeremyjh 3y agoKinetic energy is definitely the better design and test metric. But you still can't claim a linear relationship without large - yet controlled studies. And if it is as good as they, a large/long trial could be unethical versus just widely deploying it and collecting the data you can. It is just as likely it is only twice as good at preventing concussions. The headline is almost click-bait.
