For anyone who's had a concussion before, you know those things aren't fun. Your vision is blurry, you can't make proper sentences and falling down is a constant thing. Ok, and of course there's also the fact you've got some kind of brain damage.
Mouthguards in derby are supposed to help prevent that to some extent--when you fall on your head the force of impact can be distributed and absorbed by your jaw and your mouthguard is there to reduce the injury to your body. But the problem is that there's little research on concussions in derby specifically--I mean, we've adopted our safety gear from other sports, and we're still in the early days of knowing how to protect ourselves in a way specific to our sport.
So, the next best thing from actually being able to protect yourself specifically for your sport is to be able to protect yourself generally, AND also get information about how these injuries are occurring. I'm a big fan of information gathering. Enter the FITGuard mouthguard, which has an indicator to tell you the likelihood of your having a concussion in a pretty foolproof way.
Here's an article on HuffPost about it. In particular, they say:
The FITGuard has a green LED strip on the front that turns blue when it detects a medium force impact and red when there’s an above-50 percent chance the athlete has suffered a concussion. The athlete can then use an app to download a data log showing why the guard is displaying a given color. The data will also be uploaded to a central database to help the FIT team improve the device.
Yeah, so that's a handy-dandy way to helping determine the injury. Plus one thing that's good is that you can tell without having to take the skater's helmet off (which might make things worse if they have some other injury, e.g. to their neck).
Plus it's a LED strip so you'd glow in the dark (maybe)!
It kind of reminds me of those stickers they put on things in Mythbusters to measure G Forces or whatever (for illustration, here's the Exploding Water Heater episode, the stickers are at 0:35 onwards but stick around for the explosions):
Yeah, I'm glad my head doesn't do that when I get a concussion.
