The #Qcollar jugular compression device is "FDA CLEARED" to "protect athletes' brains during head impacts." @US_FDA

Does this mean that it is safe, effective, and based on sound science?

Not quite! Before you believe the company's big claims, read this full thread!
Below is an index to my fully-referenced thread:

2/ A bit about what FDA cleared really means
3/ Critique of the study that got Qcollar FDA cleared
4/ Summary of problems w/ their other studies
5/ Qcollar's continued pattern of false claims
6/ Their plan to profit from taxpayers

Some semantics, note this isn't "FDA APPROVED" but rather "AUTHORIZED".

QCollar isn't claiming "approval," but many confuse these terms and assume this more stringent standard.

APPROVAL is more appropriate for Class III devices, which undergo more rigorous review.

@US_FDA approved the #Qcollar jugular compression device to "protect athletes' brains during head impacts."

This decision was based on VERY FLAWED DATA and does NOT demonstrate the safety or effectiveness of the Q-collar.

Here is the text from the @FDADeviceInfo press release.

If you don't understand the highly nuanced #MRI technique known as DTI, these results sound straightforward and convincing.

THEY ARE NOT. Don't be fooled by these numbers!🤔

I will dissect these in the thread below. Image

"No significant changes" is based AVERAGE response, not individual.

First, an easy-to-understand analogy below.

If half the sample experiences an increase and half experiences a decrease, they can cancel each other out to falsely suggest "no change" when one does exists! Image

Does the woodpecker-inspired #Qcollar protect the brain & prevent #concussion?

Take 3 minutes to read this fully referenced thread presenting evidence that a jugular compression collar is unlikely to keep athletes safe

Please SHARE, help inform others!

The #Qcollar is based on the idea that jugular compression increases blood in the brain to create a "bubble wrap" effect, which prevents the it from bouncing around inside the skull.

According to the company, this mechanism is found in Nature.

From the company's promotional video, the device is justified based on reducing brain "slosh" by:

1) Replicating the animal adaptations (see 18:00 in video)
3) Replicating effects of "higher altitude" exposure (see 21:57, again at 36:00)
