In previous articles we discussed the potential injuries that can occur due to misuse of a computer/workstation. These injuries are usually the result of 1) repetitive use of a computer and/or its accessories, 2) the setup of your workstation or 3) due to improper positioning of your body when using a computer. This article will discuss some strategies you can use when purchasing or setting up a computer/workstation to best meet your individual needs and to prevent injury.
Monitors:
- Make sure the screen is large enough for adequate visibility. Usually a 17 to 20-inch monitor is sufficient, smaller units will make it difficult to read characters and larger units may require excessive space.
-The angle and tilt should be easily adjustable.
- Flat panel displays take less room on the desk and may be more suitable for locations with limited space.
Keyboards:
-Split keyboard designs will allow you to maintain neutral wrist postures.
- Keyboards with adjustable feet will accommodate a wider range of keyboard positions and angles. Adjustable feet on the front as well as the back will also enable adjustments. Increased adjustability will help you to have your wrists in a straight position.
-The cord that plugs into the CPU should be long enough to allow you to place the keyboard and the CPU in a variety of positions. There should be at least six feet of cord length.
-Consider a keyboard without a 10-key keypad if the task does not require a standard keyboard. If the task does require one occasionally, a keyboard with a separate 10-key keypad may be a good choice. The 10-key is preferable because it allows you to place the mouse closer to the keyboard.
-Consider the shape and size of the keyboard if a keyboard tray is used. The keyboard should fit comfortably on the tray.
- Consider keyboards without a built-in wrist rest, because separate wrist rests are usually better.
- Keyboards should be detached from the display screen if you are using them for prolonged typing tasks.
- Laptop keyboards are generally not suitable for prolonged typing tasks.
Keyboard Trays:
- Keyboard trays should be wide enough and deep enough to accommodate the keyboard and any other
devices, such as a mouse.
-Keyboard trays should have adjustment mechanisms that lock into position without turning knobs.
Wrist Rests:
- Wrist rest should match the front edge of the keyboard in width, height, slope, and contour.
- Pad should be soft but firm. Gel type materials are recommended.
- Wrist rest should be at least 1.5 inches deep(away from the keyboard) to minimize contact pressure
on your wrists and forearm.
In our next article we will discuss other environmental modifications that can be implemented to help prevent injury during computer use. These are just general suggestions for preventing injury and promoting ease when using a computer. Consult an occupational or physical therapist to address your individual needs and limitations so that you can function at your best.
