Makers of the Q-Collar claim that the device protects against concussion. The FDA cleared it for sale even though they doubted the evidence for that claim. via The Washington Post realclearscience.com/2025/10/18/fda…

A wearable “brain protection” device known as the Q-Collar is increasingly used in contact sports in the US. Despite being pitched as “proven to help protect the brain," the Q-Collar is beset by scientific problems, find James Smoliga, DVM, PhD and Mu Yang BMJ Group bmj.com/content/391/bm…

"In the case of Q-Collar, our new investigation reveals data irregularities in some of the studies that supported the device’s approval by the FDA. Is this how athletes should be treated?" Kamran Abbasi on the story of Q-Collar in Editor's Choice bmj.com/content/391/bm…

I truly feel for Sauce Gardner—not just for the concussion, but for believing the Q-Collar could actually protect his brain. A few days ago, The Washington Post featured SAUCE GARDNER in their investigation questioning the evidence behind it. washingtonpost.com/sports/2025/10…

I feel bad for Sauce Gardner and all of the other athletes who are trusting their short- and long-term brain health to the Q-collar. They see "FDA authorized" and "proven safe and effective" based on 25+ scientific publications. But do they understand how weak the evidence is?

Does the Q-Collar really work? 🤔 A new investigation casts doubt on the theories behind the device and the science supporting it. Here's what contact sport athletes and parents need to know.

The duplicated tables I found seem to be the catalyst of a lot of the recent discussions/discoveries. However, I never explained how I found the duplicated tables. At this point, the fact that they were duplicated in two papers seems to be the least serious problem in my opinion,

"Patients and consumers shouldn’t need a FOIA request to understand whether “FDA authorized” reflects compelling evidence or a device permitted despite serious internal concerns, addressed only through labeling caveats." STAT statnews.com/2025/11/02/q-c…

We see terms like "FDA authorized" and assume that means proven effectiveness. The reality is not so clear cut.

Time to dive into this more..always been skeptical about the Q collar and seems people much smarter than me feel similar

Parents shouldn't need a Freedom of Information Act request to understand the evidence, or lack thereof, behind sports protective equipment that their kids are using. When U.S. FDA reviewers say the evidence is unconvincing, but authorize it anyway, that's seems problematic.

The U.S. FDA authorized a “brain-protection” collar for athletes — even after its own reviewers doubted its clinical effectiveness. My new STAT First Opinion explains how that happened, and what it reveals about the system meant to protect us.

Is The Mattingly Curse real? Toronto Blue Jays Don Mattingly made the playoffs 11 times—but has 0 World Series rings. I ran the math. Turns out there’s a 29% chance this would happen by luck alone: humanlimits.substack.com/p/the-don-matt… In other words, he’s not cursed. He’s probability personified.

Few in the life sciences, MDs or PhDs, have a strong grasp of statistics. Many who do are treated like technical support, called in to generate p-values or pretty figures of heat maps the way the IT guy is summoned to fix the Wi-Fi. The ones with statistical skills tend to sit

This came up in my feed and immediately triggered my BS detector. The “$2 depression test” detects BDNF in saliva, not depression in people. Cool engineering, zero diagnostic data. Saliva ≠ brain, correlation ≠ diagnosis, prototype ≠ clinical tool. emjreviews.com/en-us/amj/inno…

Great column about Jaxson Dart's concussion.

.Jaxson Dart's concussion was eye opening. Seemingly knocked unconscious. Grabbed his head. Yet, didn't pull himself out. Took a while to finally be evaluated by New York Giants. Why do NFL stars avoid disclosing concussion symptoms? It's complex. My take: humanlimits.substack.com/p/the-concussi…
