Research initiatives to make players safer on and off the field have been in development for the past decade at many universities, including Wake Forest University, UNC Chapel Hill and Virginia Tech. All have worked on the development of helmet sensor technology to help detect traumatic head injuries, as they happen.  However, not everyone thinks helmet sensors are the answer to preventing head injuries.

"Helmets are not going to prevent concussions," said Dr. Fred Mueller, director of the National Center for Sports Injury Research at UNC Chapel Hill. "If you had an athletic trainer in every high school and middle school in the state, it would help a lot. The problem is the funding is just not there."

The dangers associated with head injuries are increasingly well-reported in the media. However, increased awareness has led some people to seek out concussion remedies and prevention tools that are not validated. In many cases, products claiming to offer "protection" and "faster recovery" are unproven and offer a false sense of security.

Though parents routinely ask for a 'concussion-proof' helmet, there is no way to prevent a brain injury... short of not participating in the sport.
