The Science and Validation Behind iMG Technology

Any parent handing their child a piece of wearable technology and being told "this helps keep them safer" has every right to ask: says who, and based on what?

That's a fair question, and it's one worth answering with more than a marketing claim. Here's where the Prevent technology actually came from, and how it's been tested.

It started in a hospital, not a startup garage

The Prevent instrumented mouthguard technology didn't begin as a consumer gadget idea. The underlying research originated at the Cleveland Clinic, where researchers developed and validated an early prototype through peer-reviewed research. Prevent Biometrics was founded in 2015 specifically to take that clinical research and turn it into something teams and athletes could actually use on the field. The team behind it includes doctors, engineers, and mathematicians (some with NASA backgrounds), supported by a board of neurosurgeons and research scientists spanning biomechanics, materials science, and software engineering.

That lineage matters. A lot of consumer wearables start with a sensor and work backward to find a use for it. This technology worked the other direction: it started with a clinical research question - how do we accurately and objectively measure head impacts in real time - and spent roughly a decade being refined before reaching the field.

Independent validation, not just internal testing

It's one thing for a company to say its own product works. It's another for outside researchers, with no financial stake in the outcome, to test it and publish the results. This technology has been the subject of over 20 published academic studies from institutions including:

Independent, head-to-head comparisons have also found this system outperforming competing instrumented mouthguards on the market - which is a meaningfully different claim than simply "we tested our own product and it works fine."

A recognized standard, not a niche tool

In 2021, World Rugby - one of the most safety-conscious governing bodies in contact sports - selected this technology as its head impact monitoring system of choice, and it remains the only instrumented mouthguard approved to meet World Rugby's official Instrumented Mouthguard Performance Specification, verified through independent testing institutes. Dr Éanna Falvey, World Rugby's Chief Medical Officer, has publicly described it as "a complete game changer" for advancing player welfare at the international level.

It's also the U.S. Department of Defense's only head impact data provider - an interesting vote of confidence, since military researchers studying blunt force exposure and combat training have similarly demanding accuracy needs.

Beyond the World Rugby endorsement, Joseph Maroon, the NFL's longest-serving neurosurgeon, has called it "the most advanced head impact monitor system available today."

Ongoing research, not a finished product

Part of what makes this space credible is that the research hasn't stopped. Teams and universities continue to use this data to ask new questions: how head impact exposure compares between girls' and boys' sports, how impact patterns differ between practice and games, how workload accumulates across a season, and how findings from elite programs like World Rugby's international competitions might inform safety standards further down at the community and youth level.

That ongoing academic scrutiny is, frankly, a good thing. It means the thresholds used to trigger alerts, and the science behind how impacts are interpreted, are continuing to be tested and refined by researchers outside the company itself - not set once and left alone.

The takeaway for parents

When you're evaluating any safety technology for your child, it's reasonable to ask whether the science behind it holds up to outside scrutiny. In this case, the honest answer is: yes, extensively, by researchers at major universities and medical institutions with no financial interest in the outcome, and by sports' own governing bodies at the international level.

What's next

In our final post, we'll answer the most common questions parents and athletes actually ask once they've decided to look into this technology - comfort, safety of the electronics, who sees the data, and a few myths worth clearing up.
