The helmet worn by American troops fighting in Iraq and Afghanistan does little to protect against brain injuries.
But as the Los Angeles Times reports, researchers at the Massachusetts Institute of Technology say a redesigned helmet that includes a face shield could do more to guard soldiers and Marines from the concussive effects of explosions.
A face shield, according to the MIT study, could deflect the waves of force from an explosion away from the soft, susceptible facial tissues, thus lowering the risk of a concussion.
Experts said the study, which used computer simulations to test the effects of explosions, could eventually lead to new helmet designs.
“I think it will turn out to be a consideration in the future redesign of helmets,” said Eric G. Blackman, a physicist from the University of Rochester.
The helmet previously came under fire in an August report that said it actually increases the likelihood of a concussion. The MIT study disagreed with that finding, but found the helmet used by American troops is ineffective.
Traumatic brain injuries have been among the largest threats to service members, with more than 188,000 cases among personnel who served in Iraq and Afghanistan, according to military diagnoses.
But some fear that the number could be much higher, because brain injuries are easy to overlook. The Rand Corporation estimates that up to 320,000 veterans of the Iraq and Afghan wars have suffered traumatic brain injuries.
