Virginia Tech Helmet Lab Announces First Four-Star Rating for New Hockey Helmet

A newly released hockey helmet has earned four out of five stars from the Virginia Tech Helmet Ratings, scoring higher than any other helmet since the first hockey ratings were released two years ago.

The new helmet, the Bauer RE-AKT 200, is the first to earn more than three stars. The star rating system, developed by researchers in the Virginia Tech Helmet Lab, rates a helmet’s ability to reduce the risk of concussion in the event of a head impact. All sports helmets, including those for hockey, must meet an impact-protection standard that evaluates the ability of helmets to minimize catastrophic head injury on a pass-fail basis.

“We supplement the standard by providing additional data so consumers can see the relative differences between helmets,” said Steve Rowson, an assistant professor of biomedical engineering and mechanics in the College of Engineering and director of the Helmet Lab. “We make that data available and release our testing methodology, which then becomes an additional design tool for the manufacturers.”

Using a headform instrumented with sensors, the Helmet Lab team simulates a range of impacts that a player might experience during a game, and measures how much the helmet reduces the head’s linear and rotational acceleration.

Rowson and Stefan Duma, the Harry Wyatt Professor of Engineering and interim director of the Institute for Critical Technology and Applied Science, began evaluating football helmets in 2011, designing the test methods based on millions of impacts they recorded from Virginia Tech football players.

The Helmet Lab team started testing hockey helmets a few years later, and has since rated more than 40 models.

Hockey players hit their heads on the ice, the glass around the rink, or each other; these surfaces can be rigid and players are typically traveling at high speeds, so impacts may be more severe than in other contact sports.

And hockey helmets tend to be light and thin, which limits their ability to reduce the force of a hit. In order to effectively absorb energy during an impact, thinner foam must be stiff. Thicker, softer foam that has more time to compress can cushion a broader range of impacts. The new Bauer helmet has slightly thicker padding than other models.

“I think this is the first example of the hockey helmet manufacturers using this test methodology and ratings protocol to influence the design,” Rowson said. “What we wanted to do was set a framework for improvement in protective design.”

The team’s methods have already contributed to improvements in football helmet design. When the first batch of ratings was released, only one helmet earned five stars. Today, 16 do, and virtually all new helmets get high marks.

“With the helmet ratings, we provide unbiased data and a transparent process that manufacturers can use to inform their design process and consumers can use to guide their choices,” Duma said. “We’ve been glad to have the opportunity to work with helmet companies to drive innovation, because we all have the same goal: to keep athletes as safe as possible.”

The team is also developing five-star ratings for bicycle and lacrosse helmets and soccer headgear.

Rowson says that helmets are just one piece of the equation in eliminating concussions. Behavioral changes in sports — for example, banning body-checking in youth hockey — can make an even more significant difference in reducing the number of injuries.

“You want to eliminate as many head impacts as you can, and then have the very best head protection in the event that you do hit your head,” he said.

The team’s current ratings are available online, and updated on a rolling basis.

Technology Preventing Brain Injury Inspired by Woodpeckers

By Brooks Schuelke of Perlmutter & Schuelke, PLLC

It is difficult to imagine that a bird and a football player have much in common, but they do, and the lowly woodpecker just may hold the key to making safer football helmets.

The history of football is rife with attempts to make a better helmet for players to prevent skull fractures. While the technology does exist to prevent or diminish skull fractures, there is little to no protection from brain injuries. This is where the woodpeckers come into play.

Dr. Gregory Myer, is the director of research and the human performance lab at the Cincinnati Children’s Hospital Sports Medicine division. Myer was contacted by Xennovate Medical’s CEO, David Smith, who was enthused about the possibilities of a possible breakthrough in brain injury care. The idea proposed came about as a result of studying woodpeckers.

Smith explained to Myer that woodpeckers prevent concussions by wrapping their tongues around their jugular veins to increase blood flow to the brain. This keeps the brain from moving about inside the skull while the bird hammers on wood. Myer understood that since the bird could not protect its head from the outside, the adaptation of winding its tongue around its jugular would prevent brain injuries. Mayer began research on the “Q Collar,” also known as the Neuroshield, which is designed to be worn around the neck and increase blood flow to human brains.

The initial prototype Neuroshield performed well in field tests with high school football teams, soccer teams and a SWAT team. The promising results may give the Neuroshield a chance that it could be pressed into service for the U.S. military. Although there is still more research to conduct, if the theory behind preventing brain trauma is correct, the collar may become an integral part of daily life and even be used while riding a bike or motorcycle. It is anticipated that the collar manufacturer, the Performance Sports Group, may put the product on the market by 2018.

LAX Helmet Manufacturer Says It ‘Raises Bar on Protection’ with New Helmet

Cascade Lacrosse, which bills itself as “the leading helmet manufacturer in lacrosse,” today launched a new premium helmet, the S. Designed and manufactured in the United States, the new S represents “the pinnacle of protection,” among other things.

The S, which sells for $289, incorporates several “new, game-changing helmet technologies, including a new tri-liner integrated with the shell,” according to the company.

Specifically, the company notes the “protection” aspect – “Three different liner technologies unite to optimally address variable force impacts. This tri-liner system integrates perfectly with the SuperMono S shell to create the ideal protection package.”
