Sitting At The Computer

From the June 2011 Chiropractic Journal

Millions of people work with computers everyday.  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.  However, 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 is helpful to understand the concept of neutral body positioning.  This is a comfortable working posture in which your joints are naturally aligned.  Working with the body in a neutral position reduces strain and stress on the muscles, tendons, and skeletal system and reduces your risk of developing a musculoskeletal disorder (MSD).  the following are important considerations when attempting to maintain neutral body postures while working at the computer workstation.
  • Hands, wrists, and forearms are straight, in-line, and roughly parallel to the floor.
  • Head is level, or bent slightly forward, forward facing, and balanced.  Generally it is in-line with the torso.
  • Shoulders are relaxed and upper arms hang normally at the side of the body.
  • Elbows stay in close to the body and are bent between 90 and 120 degrees.
  • Feet are fully supported by the floor or a footrest may be used if the desk height is not adjustable.
  • Back is fully supported with appropriate lumbar support when sitting vertical or leaning back slightly.
  • Thighs and hips are supported by a well-padded seat and generally parallel to the floor.
Regardless of how good your working posture is, working in the same position or sitting still for prolonged periods isn't healthy.  You should change your working position frequently throughout the day by:
  1. making small adjustments to your chair or backrest;
  2. stretching your fingers, hands, arms, and torso;
  3. standing and  walking around for a few minutes periodically.
If you would like more help in determining how to set up your computer workstation, please ask one of our chiropractors or physical therapists.
