The Q Collar is a device designed to prevent concussions by protecting the brain from the inside of the skull. There are however some potential issues with this device and the research behind its apparent success.
Dr. Cameron Marshal goes into detail about this during Episode #61 of Ask Concussion Doc.

I bought it for my son since he's had 2 concussions prior to having the q collar and also with a skull cap hasn't had one since,but still remain skeptical if it does what it says im willing to spend whatever it takes to protect my child
...then keep him out of contact sports?
The summary below of a 2018 study is posted in the Q-Collar website. It sounds like this study is the same or very similar as the study the doctor in the video suggested. Players with and without the Q-Collar had accelerometers in their helmets to measure impacts and they had pre and post season brain scans to determine changes in brain matter.
I am certainly no experts on concussions or brain damage, but this sounds like a well designed study to me. The methods seem sound and the sample size is robust for this type of device study. The FDA approved the Q-Collar device based on the results of this study, which is a huge accomplishment. I was in pharmaceuticals for 23 years, so I know how incredibly difficult it is to get FDA approval for medications and medical devices.
VII. FOOTBALL PIVOTAL TRIAL (2018)
The pivotal study that resulted in FDA approval, utilized a prospective controlled trial to evaluate the effects of mild jugular vein compression (n=142 collar/intervention device) relative to controls (n=142 non-collar controls) during a competitive football season. Magnetic resonance imaging data were collected from participants pre- and postseason and head impact exposure was monitored by accelerometers during every practice and game throughout the competitive season.
Athletes’ accumulated head impact exposure was systematically thresholded based on the frequency of impacts of progressively higher magnitudes (10g intervals between 20 to 150g) and modeled with pre- to postseason changes in DTI measures of white matter as a function of jugular vein compression (JVC) neck collar wear.
The findings revealed that the JVC neck collar modulated the relationships between greater high-magnitude head impact exposure (110 to 140g) and longitudinal changes to white matter, with each group showing associations that varied in directionality. Results also revealed that 77% of the collar wearing athletes did not have significant changes to their white matter of the brain, while 73% of the non-collar wearing athletes had significant changes.
Importantly, there were no reported adverse events. Collectively, these data indicate that a JVC neck collar can provide a mechanistic response to the diffusion and anisotropic properties of brain white matter following the highly diverse exposure to repetitive head impacts in American tackle football.
Yes, but the problem is in the form of measurement - you'll notice that in all of their communications/marketing and likely in the FDA approval (which I haven't looked at) you likely won't find any verbiage around protecting against concussion. They'll say things like "protects the structural integrity of the brain" - which no one really knows what that means so they infer concussion. The evidence on concussion prevention is minimal to non-existent. Secondly, the study you are referring to used Diffusion Tensor Imaging as the modality of choice. In the same paper that this was published there was a commentary by other researchers which challenged the validity of using this modality since we don't know what the findings actually mean - could it be that changes in white matter structure over time actually confer some sort of protective effect? If so, is this device potentially leading to problems downstream that we are not aware of yet? This study specifically talked about "subconcussive impacts" which are next to impossible to define and we don't know if there is any potential effect of the subconcussive range at this time. My only point in this video is that the device does not protect against concussion...It might but that has not been shown in the research.
It appears that since this video has come out they now have put this on their website. I'm curious what you think of the new studies that have occurred since you released this video
""FDA-Cleared” reflects the highest level of review and authorization by the FDA for a non-invasive, low-risk device like the Q-Collar.
The FDA reserves use of the word “approved” for high-risk devices, such as a pacemaker. Following its thorough evaluation of the independent research, the FDA announced that the Q-Collar (a Class 2 medical device) safely and effectively “provides an additional piece of protective equipment athletes can wear when playing sports to help protect their brains from the effects of repetitive head impacts.”
It seems like it would prevent adequate blood flow TO the brain as well.....
I have been playing football my whole life. And am now playing professionally overseas. I have seen Luke Keuchly wearing one in the past. Would you recommend someone like myself buying one and trying it out. I know it's not proven, but I would be interested to see if it helps
So does it work or not?
It has not shown to prevent concussions in any way
@@CompleteConcussions does it help reduce repetitive impact injuries
@@enforcerofdoom6185 we aren't really sure if repetitive impacts cause issues at this point. It's quite controversial. So since we can't define what this is or what the impact/outcome is, we can't know if this device protects against it.
@@CompleteConcussions thanks. I think your videos on this saved me 200 bucks
@@CompleteConcussions A statement of that nature is just short of saying, "repetitive impacts DO NOT cause issues". If the QCollar can't say that it will prevent concussions then it shouldn't be correct to say that repetitive impact don't cause issues. We all know that definitive statements equate to liability. What's more constructive is a comparison to the the alternative of a QCollar which currently is NOTHING. So, to that point does the evidence show that there's a benefit in comparison to NOTHING?
"with no trauma whatsoever"
I beg your PARDON!
I’m gonna need more context here…
