BLACKSBURG, Va. — Hockey helmets may be on the verge of a radical makeover, as scientists and engineers at Virginia Tech prepare a rating system that measures each brand’s and model’s ability to reduce the risk of concussion.

“After football, hockey is the sport that produces the highest rate of concussion,” said Dr. Stefan M. Duma, a Virginia Tech professor and the head of the university’s biomedical engineering department. “We want to produce a mechanism to try and reduce that risk of concussion.”
