New study finds differences in concussion risk between football helmets

31.01.2014
Football helmets can be designed to reduce the risk of concussions, according to a new study by some of the nation's leading concussion researchers published today in the Journal of Neurosurgery.

The study analyzed head impact data compiled from eight collegiate football teams that included Virginia Tech, University of North Carolina, University of Oklahoma, Dartmouth College, Brown University, University of Minnesota, Indiana University, and University of Illinois.


The ability of the Riddell Revolution (left) and the Riddell VSR4 (right) helmets to reduce concussion risk was compared in the study. A significant difference in concussion risk between these two helmet designs was found by the authors.

Six years of data were collected between 2005 and 2010. During this time a total of 1833 players wore helmets that were equipped with sensors to measure the biomechanics of over one million head impacts. All players either wore a Riddell VSR4 or Riddell Revolution helmet. The researchers compared the rates of concussion between the two helmet types.

The manuscript reports a 54 percent reduction in concussion risk for players in the Riddell Revolution compared to players in the VSR4 helmet. "This is the first study to control for the number of times players hit their heads when comparing helmet types," said Steve Rowson, lead author and an assistant professor in the Virginia Tech – Wake Forest School of Biomedical Engineering and Sciences.

"No previous study has been able to account for this variable. Controlling for head impacts allows you to compare apples to apples. For example, you're not comparing a player in one helmet who rarely gets hit to a player in another helmet type who frequently gets hit."

The sensors in the helmets measured head acceleration for each impact players experienced. Players in the VSR4 helmets experienced higher head accelerations resulting from impact than players in Revolution helmets. The authors attribute this to the Revolution helmets better modulating the energy transfer from the impact to the head, which results in lower head accelerations. "Helmets that better lower head acceleration reduce concussion risk," Rowson said.

The authors stress that no helmet will ever be able to prevent all concussions. "While some helmets will reduce risk more than others, no helmet can eliminate risk," said Stefan Duma, professor and head of the Virginia Tech – Wake Forest School of Biomedical Engineering and Sciences. Better helmet design is just one of many strategies that play a role in reducing concussions in football. "The most effective strategies are altering league rules and teaching players better techniques. These strategies focus on reducing the number of head impacts that players experience," Duma added. "However, head impacts in football will always occur, even with the best rules and technique. This is where improving helmet design to best reduce concussion risk becomes critical. Our data clearly demonstrate that this is possible."

In addition to Rowson and Duma, other authors of this study were Richard Greenwald, Jonathan Beckwith, and Jeffrey Chu of Simbex, Kevin Guskiewicz and Jason Mihalik of the University of North Carolina, Joseph Crisco and Bethany Wilcox of Brown University, Thomas McAllister of the Indiana University School of Medicine, Arthur Maerlender of Dartmouth College, Steven Broglio of the University of Michigan, Brock Schnebel and Scott Anderson of the University of Oklahoma, and Gunnar Brolinson of the Edward Via College of Osteopathic Medicine.

Im Focus: UNH scientists help provide first-ever views of elusive energy explosion

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.

Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
