Recently, with the spread of personal computers, more and more people are working with computers. In addition to computer work, a lot of time is spent on computers by computer games among teenagers. In other words, people who work or play games for a long time on a computer for computer work, computer games, etc. often complain of muscle pain in the wrists, joints, neck, back and shoulders. In addition, these symptoms are frequently seen in adolescents in recent years, and are easily found in the majority of office workers who use computers, and various syndromes caused by these symptoms are becoming social problems.

Some examples include Video Display Terminal Syndrome (VDT syndrome) and Carpal-tunnel syndrome. These syndromes include workers who perform computer work or play games for a long time. Comes from an incorrect posture.

That is, when working with a conventional computer, as shown in FIG. 1, the monitor M, the keyboard K, and the mouse are placed on the desk 1, and the chair 1 is seated on the desk 1. The keyboard K and the mouse are operated. In this case, the user may use the keyboard and the mouse in a state in which the wrist is folded down while lifting the entire arm to some extent, or the arm is supported on the desk and the wrist is folded upward. When using such a computer keyboard and mouse, if the tension state such as bending the wrist or lifting the arm lasts for a long time, the stress on the shoulder is stressed by the weight of the lifting arm, causing wrist tunnel syndrome such as agglomeration or wrist bending. do.

Therefore, most people use their hands with their backs folded when using a computer keyboard and the like. If the hands are used only in one direction, the muscles and joints of the hands are skewed in a specific direction. In addition, due to this bending, physiological functions such as blood circulation are not performed smoothly, which causes pain or swelling around the wrist or coldness of the hand. In addition, the mouse touch finger syndrome is one that appears with such a wrist syndrome. In the mouse touch finger syndrome, when the mouse is used for a long time, the mouse is used in the same posture while the finger is pinched, and the symptoms are the same as those of the wrist tunnel syndrome.

Therefore, the correct posture of the user when working or playing on a computer is the most important for the prevention of the wrist tunnel syndrome and the mouse tunnel finger syndrome. In other words, the wrist tunnel syndrome is a symptom caused by the compression of the nerves of the wrist, so that the wrist should not be bent for a long time.

Meanwhile, in addition to the above-described wrist tunnel syndrome and mouse touch finger syndrome, when the computer is used for a long time, when working with the arm placed on the desk, the user sits close to the monitor, which causes X-rays and ionizing radiation emitted from the monitor. Video Display Terminal Syndrome (VDT syndrome) is frequently caused to be exposed to harmful electromagnetic waves and cause symptoms such as headache as well as visual impairment.
