CHICAGO, Feb. 22, 2011 /PRNewswire/ -- An Illinois high school hockey coach is taking the pro-active approach to concussion awareness and detection.
Tim Johannes, who coaches at Stevenson High School, invented the Shockwave System , designed for anyone wearing helmets with the risk of sustaining a concussion, including athletes, firefighters and military members.
The Shockwave System  is a three-step system, starting with baseline testing to assess the person's balance in a non-concussed state. This data is recorded onto the form that comes with the Shockwave System. Step two is placing the Shockwave device, which is about the size of a postage stamp, onto the helmet. This device is calibrated to change colors (from white to red) when an impact exceeding its rated G-force has been sustained. The third step is learning about concussions and what symptoms to look for.
The Shockwave System measures the G-force that the helmet receives from contact. G-force is the measure of the forces applied to the brain during acceleration or deceleration injuries. The device is calibrated for the age-group that will be wearing the helmet and what medical studies have shown as to how much G-force they can sustain.
"If not diagnosed properly, concussions can leave a person severely injured for the rest of their life," Johannes said. "The Shockwave System will not prevent the first impact concussion. But, if triggered, the Shockwave System can prevent the second impact syndrome that can happen when someone who is suffering a concussion is hit a second time."
The Stevenson High School hockey team was the first organization to use the Shockwave System ($21.95), and now numerous teams and leagues – in multiple sports and at multiple levels – are using it.
