Eric Piper, an American professor, said that 80% of people feel uncomfortable after using a computer, and one of the main reasons for discomfort is using a mouse.
This is not sensational. In San Francisco, computer-related complaints increased in the 1990s. 22% of computer operators in computer companies feel shoulder and arm pain. Among newspaper employees, 44% suffered from shoulder and arm injuries due to computer use. The loss caused by the injury exceeded $654.38 billion. Each injured person spends an average of $29,000 on treatment and rehabilitation.
The pain caused by the mouse comes from the operator's sitting posture leaning forward and improper mouse placement. Being in this state for a long time is easy to make people nervous, because the mouse is usually placed next to the keyboard, so when you reach out and use the mouse, your neck, arms and shoulders will bear twice as much pressure as usual. Nerve muscles pinch nerves, and there will be pain in shoulders and wrists.
To avoid this problem, you have two choices: first, straighten your back and neck, which can reduce stress. Second, move the mouse close to you and do the above two jobs well so that your illness can be cured without seeking medical help.
