For example, the grading system can assist recreational athletes and coaches in recognizing the symptoms and guiding them as to when athletes who have suffered concussions can return to their activity. We fully support that. On a professional level, we have the ability in the NHL to collect data on every concussion that occurs. Our goal is to discover what the most important and consistent symptoms are and to see how we can translate these into diagnosing and treating the players. As an orthopedic surgeon, I look at forces exerted on the muscloskeletal system.
Force equals mass times acceleration.
So as athletes get bigger, stronger and faster, the forces increase. As the forces increase, especially in contact sports, the potential for all injuries increases, including head injuries. It's a standard principle of physics, with a little statistics thrown in. People should always wear helmets when playing contact sports or riding their bicycles and motorcycles. Another vital element is educating the general public.
