The reason why this disease quickly becomes a common modern civilization disease is that the lifestyle of modern people changes dramatically, and more people use computers for a long time every day. Most of these people repeatedly type and move the mouse on the keyboard every day, and the wrist joints are intensive, repetitive, and over-active for a long time, resulting in paralysis and pain of the wrist. Other occupations that may have a similar impact, such as musicians, teachers, editors, architects, and miners, are related to the frequent use of both hands. According to a survey from Singapore, female is the biggest victim of "wrist canal syndrome", which is three times higher than that of male, because female hand canal is usually smaller than male, wrist median nerves are prone to oppression.
