Ergonomic Guidelines for arranging a Computer Workstation

Since computer ergonomics is such a big issue in repetitive motion injures we will be looking at each step for proper workstation arrangement over the next few months. Please don't forget that if you need a workstation evaluation you can call me and have one arranged.

1. How will the computer be used?
   • Who will be using the computer? If the computer will be used only one person, then the arrangement can be optimized for that person's size and shape, and features such as an adjustable height chair may be unnecessary. If it's going to be used by several people, you will need to create an arrangement that most closely satisfies the needs of the extremes, that is the smallest and tallest, thinnest and broadest persons, as well as those in between these extremes.
   • How long will people be using the computer? If it's a few minutes a day then ergonomic issues may not be a high priority. If it's more than 1 hour per day it is advisable that you create an ergonomic arrangement. If it's more than 4 hours then you should immediately implement an ergonomic arrangement.
2. What kind of computer will be used?
   • Desktops - most ergonomic guidelines for computer workstation arrangements assume that you will be using a desktop system where the computer screen is separate from the keyboard.
   • Laptop computers are growing in popularity and are great for short periods of computer work. Guidelines for laptop use are more difficult because laptop design inherently is problematic - when the screen is at a comfortable height and distance the keyboard isn't and vice versa. For sustained use you should consider purchasing either:
     1. An external monitor
     2. An external keyboard, preferably with a negative tilt keyboard
     3. Both, and
     4. A docking station

Ideal typing posture: Negative slope keyboard support
