Why Should the Wrist Be Protected? The wrist joint is an important yet fragile joint in the human body. Any action that requires the use of hands needs the coordination of the wrist. If injured, it will seriously affect daily life. The common population is mainly reflected in middle-aged and elderly people, and women are more likely to suffer from it than men. With the popularity of mobile phones and computer office work, "keyboard hands" and "mouse hands" are becoming increasingly common, and tenosynovitis in young people is also becoming more frequent.
