Millions of people work with computers every day. This article explains simple, inexpensive principles that will help you create a safe and comfortable computer workstation. There is no single “correct” posture or arrangement of components that will fit everyone. There are basic design goals, to consider when setting up a computer workstation or performing computer-related tasks.
To understand the best way to set up a computer workstation, it’s helpful to understand the concept of neutral body positioning. There are important considerations when attempting to maintain neutral body postures while working at the computer work-station.
1) Hands, wrists and forearms are straight, in line and roughly parallel to the floor. 2) Head is level, or bent slightly forward, forward facing, and balanced. Generally it is in line with the torso.
3) Shoulders are relaxed and upper arms hang normally at the side of the body.
4) Elbows stay in close to the body and are bent between 90 and 120 degrees.
5) Feet are fully supported by the floor or a footrest may be used if the desk height is not adjustable.
6) Back is fully supported with appropriate lumbar support when sitting vertical or leaning back slightly.
7) Thighs and hips are supported by a well-placed seat and generally parallel to the floor.
8) Knees are about the same height as the hips with the feet slightly forward.
Remember to change your working position throughout the day by standing and walking around, and stretching your fingers, arms, hands and torso.
