From 1995 to 1997, I worked at Suwa Central Hospital in Chino City, Nagano Prefecture. The hospital director at that time was Dr. Minoru Kamata, who became famous for the best sellsr book "Ganbarainai (Not work hard)". While emphasizing community medical care, such as conducting checkups in villages and providing guidance on lifestyle-related diseases, he invited the famous singer Masashi Sada to a hospital to hold a talk show while drinking lightly with local people, and gave lectures in various places.There are many ski resorts around here, and my family and I have gone skiing more than 20 times over the past two years.
Despite the rapid increase in the number of snowboarders, especially young people, just before the Nagano Olympics, snowboarding injuries are almost unknown, and snowboarders who have suffered head injuries and are rushed to hospital I was keenly aware of the horror of snowboarding injuries.
Together with an orthopedic doctor, we appeared on cable TV and contributed to a local newspaper (Nagano Nippo), warning that it was dangerous for beginners to start snowboarding without prior knowledge.
Snowboarding controls speed and direction by raising the edge on the mountain side, but if the edge on the valley side accidentally touches the snow surface, the board loses control, loses balance and falls, causing serious head injuries. This phenomenon is called the reverse edge phenomenon of snowboarding, and since the reverse edge phenomenon is more likely to occur on gentle slopes than on steep slopes, many beginners who do not know this cause head injuries. Beginner snowboarders should study this reverse edge phenomenon carefully and be careful not to fall over.
I compiled the results into one Japanese paper and two English papers.スノーボードによる頭部外傷.pdfsnowboard head injury.pdfJMS2002 97 snowboard mechanism.pdf
The last paper is the first in the world to prove the relationship between snowboarding reverse edge phenomenon and head injury.
