A Helmet That Detects Hard Hits

Ergonomic design yields biomechanic data ...

"There is a growing awareness that football players, from the high-school to the professional level, can suffer permanent brain damage from repeated concussions, even relatively minor ones. The impact of these blows often causes trauma to the brain that goes undetected by athletes, coaches, and medical personnel: athletes tend not to report potential injuries, while football staff often miss the signs of a concussion. Playing through such injuries puts an athlete in danger of sustaining further, more severe brain damage.

Now Riddell, a sporting-equipment manufacturer based in Rosemount, IL, is equipping its new line of helmets with sensors that measure the magnitude, location, and direction of a hit. The collected data can then be uploaded to a user's computer and analyzed with a Web-based application. The helmet system will be sold to individual consumers for the first time this fall.

The whole point of this technology is to measure the severity and location of head impacts, especially those that would otherwise go unnoticed, so that we can better understand when a concussion has occurred," says Rick Greenwald, CEO of Simbex, a research and product-development company based in Lebanon, NH. The company specializes in biomechanical feedback systems and originally developed the technology, which was acquired by Riddell in 2004.

Riddell already sells similar sensor-equipped helmets to football teams like Virginia Tech, the University of Minnesota, the University of Oklahoma, and the University of North Carolina. The helmets sold to teams, like the helmets that will be sold to individuals, are equipped with sensors that receive impact data, but for teams, this data is continuously and wirelessly transmitted to a sideline laptop, where medical staff can monitor it. The team product includes a sideline response system so that if a player takes a hit above a certain predetermined threshold, an alert will be sent to a pager worn by a trainer.

To shed light on the biomechanical causes of concussions, the National Institutes of Health (NIH) is currently funding a five-year study using data from the football teams at Virginia Tech, Brown University, and Dartmouth College. But the team system is "pretty expensive--$60,000 to $70,000. And with the individual helmet, you can receive the same type of data for about $1,000," says Thad Ide, Riddell's vice president of research and development."    (Continued via Technology Review)    [Ergonomics Resources]
