FDA Approves Device That May Help Prevent Traumatic Brain Injuries by Clamping Blood Vessels in the Neck

Mar 2, 2021 at 16:22
by Alicia Leggett  

The US Food and Drug Administration approved a device last week that may help prevent traumatic brain injuries in athletes by clamping down on blood vessels in the neck.

Odd, right? But it might have real potential. By slightly restricting blood flow through the internal jugular veins, the device, called the Q-Collar, increases blood volume in the skull, thereby limiting movement of the brain inside of the skull, which experts believe is what generally causes traumatic brain injuries.

As new research on brain injuries continues to emerge, experts have increasingly focused on ways to minimize the damage from repeated subconcussive impacts, which have been indicted for likely causing chronic traumatic encephalopathy (CTE), the degenerative brain disease that has notoriously affected football players and that results from cumulative damage over time.

To assess the safety and effectiveness of the Q-Collar, the FDA ran a series of studies, including a prospective, longitudinal on 284 high school American football players that used pre- and post-season MRI scans and accelerometer data to track structural changes in the subjects’ brains that occurred throughout a season of play. The changes found affected deep white matter regions of the brain related to electrical signal transmission and were associated with repeated head impacts.

Significant changes were found in the brains of 73% of the no-collar group compared with 23% of the Q-Collar group.

Another study looked at female soccer players and had similar findings: The no-collar group, in general, had significant white matter changes, while the Q-Collar group did not. The soccer study, however, included another MRI three months post-season, which found that the white mater changes had either resolved or partially resolved, leaving the question of whether the Q-Collar helps prevent the cumulative damage that leads to CTE.


It’s important to note that the Q-Collar is in no way an adequate replacement for a helmet and other appropriate protective gear, but it is a cool piece of gear that seems promising and might (hopefully) have benefits in a real and very scary corner of the impact and action sports worlds.

The Q-Collar is already for sale in Canada and is pending approval in Europe and the UK. Information about availability in the US will be available soon at https://q30innovations.com/.

More information about the Q-Collar and its FDA approval is available in the FDA press release.

 Why? As a teen who plays football, I don't see why we shouldn't play. By the time you get to highschool, you are either invested in the sport, or you aren't playing it. Sometimes you just have to accept risks. If getting injured playing sports is an issue, why aren't you whining about mtb, clearly you can get pretty hurt doing that.

 @jrocksdh: "great" income potential? There are 1,700 pro football players, total. The NFL hires 300 new players each year, and most of them will have very short careers. I would bet about 100 of them have a career they can retire on.
Scholarship potential is a little better - about 32,000 spots in existence (www.ncsasports.org/football/scholarships) across 900 football programs in the country. However, that's total, so any one year is on average 1/4 of that - 8,000 - and even within DI those aren't all fully funded/utilized, so call it about 6,000. There are about 4M new full time college freshman. There are ~1M highschool football players, so figure about 250k football-playing seniors. So 244k highschool seniors are damaging their brains so that 6k of their friends (2.5% of them) can get a college education representing 0.15% of all college opportunities.
Here's where it gets crazy. There are 1.7 million college scholarship opportunities in the US, of which football represents 0.35% based on the numbers above. Put another way, you have about 300X more scholarship opportunities outside of football than within it.

 @Duderz7: part of riding bikes isn't intentionally throwing your head and body at a trail. On a bike impacts are accidental and incidental, in football impacts are intentional and unavoidable.

Young people are going to do dangerous things, and are going to get hurt and thats life. That is separate from the virtual slave trade that is football. It is one of the most predatory sports at every level. There is a big difference between some kids (or adults) playing a sport, and an organization profiting off children playing a combat sport. The fact that football has embedded itself so deeply into "education" is not only disgusting, also a little counter-intuitive.

Its looking like some people took a few too many hits to the head at a young age to understand this though.
  • 16 3
 My final play / final game of HS football I was running the ball up field with two tacklers bearing down and I knew I was about to get hurt. I was playing all season injured and my heart wasn't in it and thought about all these things in my head and decided to slide/ground the ball. They tackled me anyway and I had turf stuck in my helmet and a concussion. I'm certain my back isn't right and combined with a few other concussions know that it had lasting impact. Football is hard on teens who are going nowhere with it, so is hockey and lacrosse etc. I feel at these ages the equipment should still be overprotective, even at the cost of performance. I don't know what my point is but I still regret playing football haha.

 @ki3ranb: Rugby is likely a lot safer than American Football. I played rugby from aged 8 until 19 and I don't think I got more than 2 or 3 concussions the whole time. I likely got that many or more from mountain biking and also miscellaneous accidents throughout my childhood. No doubt adult rugby involves more concussion because the hits and clearouts are super aggressive and it involves the heaviest players. However, as I understand it, there's a lot more wreckless play in American Football. A lot of American football tackles don't seem to involve tackling low and wrapping up the legs, players just hurl themselves into contact, hoping to make a big enough hit that it stop the player. They then rely on the helmet and pads to protect them. Watching American Football always looks dangerous as hell to me as a rugby player and fan.

I think it is more likely than not that the claims they are making are accurate, and that this device works at least to the degree they claim it does. However it is absolutely possible that this product has side effects-probably not "decreased blood flow to the brain" as that sounds a little too ridiculous to me-but maybe something like an increased risk of upper spine or collar bone injuries. They do claim that their trial revealed no side effects which is a fantastic sign but it is still possible we might see something happen when the product goes to market. They say over 500,000 impacts during their clinical trial, well how many of those were performed in a controlled laboratory environment? They mention animal testing, were most of those impacts done on animals that had no ability to vocalize any discomfort/impairment caused by the device? (As an aside I am very very curious as to how they did that animal testing...)

Just playing the devil's advocate here. TBIs and CTE are a huge issue and anything that can help mitigate risk for athletes is a blessing. I already ride with a neck brace and would consider adding a product like this to my ppe arsenal.

  • 1 0
 @samsq: $200 wouldn't be an average helmet. And though R&D may not be be 20million, the costs of building a factory would start around there and go way beyond. Unless of coarse, like Q-Collar, they contract their manufacturing to someone else. But just because you require a huge factory doesn't mean that justifies charging a huge premium. That is what investors are for. And essentially what every purchaser is becoming buying these at this price, except they don't get to sell those shares if they want.

Clinical trials aren't really required for a helmet to assume it will help you avoid a head injury. A blood constricting neckband probably needs those trials to convince the general user.

 @MatthewCarpenter: false. It's just not heavily tested because there isn't a ton of money behind it. The NFL and the NFL players union has a lot of horsepower. And when an NFL player or super star college player kills themselves and they find CTE relation it becomes big news.

It might not be an issue for the casual rider that maybe gets 1 in their lifetime but with athletes that compete and/or kids that are on the crazy side of the norm it's 100% an issue.

Dave Mirra brought this to people attention. People weren't really thinking about cyclists as CTE risks but if you think about it... how many times do you think that dudes head slapped off the dirt, concrete and wood ramps with and without helmets during his career? I remember when the emails and calls first started coming in when he took his life. I worked at Bell at the time which was under the same umbrellas as Riddell which was in the middle of massive lawsuits related to CTE. So when it happened everyone and their mother was asking about it.

Now years later there's much more of a focus on preventing concussions in cycling. Helmets really used to be to keep you alive during heavy trauma. But now they're steadily progressing towards adding to that with concussion prevention technology. MIPS really got that going and MIPS was heavily funded by Bell/Riddell. As was their Moto based FLEX technology. Now there's spherical mips and every other brands version of tech directly related to decreasing contact concussions and rotational concussions. They wouldn't do that if concussion and CTE were not an issue with cyclist.

Look at these older dudes, talk to them. I guarantee you nearly all of them will tell you they wish the tech was there sooner. Dave's not the only one.

Outfit a bunch of teams over an entire season and you get a pretty good consistent sample to work with. The type of blows that cause severe injury are more random and inconsistent.

 I wonder if this can be integrated into the HANS-device looking brace that Leatt has for downhill riding. I know that’s more for spinal cord injury prevention, but if the neck brace could be used as a HANS device plus this blood flow restricting device, maybe it would be even safer.

 I had this same thought. Seems like an obvious add-on to a neck brace.

 "Significant changes were found in the brains of 73% of the no-collar group, while 77% of the Q-Collar group did not exhibit any significant changes."

Can you not just say "73% of the no-collar group exhibited changes, compared to only 23% for the Q-Collar group"? What's with the weird comparison of opposing metrics here?

 It might because of the way they did their statistical analysis but I'm honestly also struggling to understand the logic behind this sentence. Presented it like this, it seems they only checked whether the brains were altered separately in two different group, and did not test the effect of the collar itself.

 Bauer used to try to sell this exact same thing a couple years ago. I worked in a sports store when they were doing that and in the two years I worked there, we sold a grand total of ZERO of these neck collars

 Huh, I almost completely forgot about this. I was actually part of the control for one of these clinical studies and got my brain scanned by MRI. Pretty cool study looking back. Glad to see its actually coming to market since the studies show it's effective.

 Studies aren’t great. Doesn’t really explain the force classification of a sub concussive hit... also the placebo effect as well. Very skeptical still. More of the concrete studies they have surround pigs and mice and not us humans

 I wonder how this affects you when you're several minutes deep into a hard effort and gasping for air. Seems like any restriction of circulation wouldn't be great. But I would still try it

 It only started to bother me at the end of the day about 6 hours in. I had a buddy try it and couldn’t wear it at all. Sort of like wearing a tie

I would certainly give it a try for Enduro and just put it on before stages.

 All jokes aside about the Nerf cock ring, what age is rugby typically started at over in the UK, AUS, and other places?
  • 7 0
 It's taught in secondary school in the UK (or was when I was there), so 11-12. Rugby is significantly different to American Football in terms of head injuries though.

 @Mayzei: All my rugby concussions came from knees to the face or slamming the back of my head on the floor. I hate the latter as the feeling is infinitely shitter

 @Mayzei: The only reason CTE hasn't been found in rugby players at the same rate as American Football players is that no has systematically looked for it yet. I guarantee you it's just as big of a problem: www.theguardian.com/sport/2020/dec/08/steve-thompson-former-rugby-union-players-dementia-landmark-legal-case

 I believe Bauer (an ice hockey brand) made a device called the neuroshield or something similar which was essentially this. Correct me if I’m wrong.

 By wearing this, how are you not risking a massive brain swelling in the case of a significant head trauma? This restricts a blood outflow from your brain, right? Right?

 @nosmallplans: It was too late for him.

It shows a lot that they're focusing on high school athletes here. Damage is well on it's way before they reach professional level sports.

 A human is the most evolved creature on the planet, especially our brain. If there was an advantage to restricted blood flow from the brain we would already have it. Deficiencies in anything killed our ancestors a million years ago. Mother nature does not believe in overkill. No thanks.
