Collared.If you've tuned in to an NFL game recently, you may have noticed something interesting around the necks of NFL players. No, it's not jewelry, but something that might be the new wave in head injury prevention: the Q-Collar.The Q-Collar is the latest attempt Garrett Richards Jersey in head injury prevention, but there's more than a bit of controversy surrounding the use and implementation of it.Still, NFL players have taken to using the Q-Collar, with more and more players using the gear during games.MORE: Here's what to know about the latest device: The Q-Collar is a small, lightweight necklace-type device to applies a small bit of pre sure to the wearer's internal jugular vein. Inside the plastic frame is a metal spring that keeps the collar in place.The idea is to increase blood flow surrounding the brain, so when there's impact, the blow is le sened, thus attempting to avoid concu sions."This puts a kink on the hose, so the jugular is slower to drain Ronald Bolanos Jersey ," "This kink fills capillaries around the brain with just about a tablespoon of extra blood, stabilizing it almost like bubble wrap." A number of NFL players have started sporting the Q-Collar in 2023, including:Chargers LB Drue TranquillCowboys RB Tony PollardCowboys TE Dalton SchultzPanthers LB Shaq ThompsonRams S Taylor RappEagles RB Boston ScottSeahawks TE Colby ParkinsonIn addition to NFL players, a number of athletes The collar puts a small bit of pre sure on the jugular veins, slowing blood flow to ve sels around the brain. E sentially, extra blood around the brain operates as almost some kind of pillow, to reduce head injuries.Per the Q-Collar website:Because the brain floats inside the skull, it moves sometimes with great force when the head is exposed to an impact. By applying light pre sure to the sides of the neck, the Q-Collar Chase Headley Jersey increases blood volume in the brains venous structures, reducing the harmful internal movement that causes brain injury.This claim, though, has been met with some skepticism from medical experts.

The FDA's approval statement says as much: "data does not demonstrate that Gerardo Reyes Jersey the device can prevent concu sion or serious head injury." "the Q-Collar has not been demonstrated to prevent long-term cognitive function deficits, and the ultimate impact on clinical outcomes has not been evaluated."Some experts also say that the theory of cushioning the brain makes sense, but could lead to other problems, including disallowing the brain to expand."The brain sits in an enclosed space within a hard skull, and thus has very little room to expand if put under additional pre sure,"All that's to say, you can wear it, but it might not do much good. There's simply not enough known yet.
