HANDS DOWN! - Decreases Strain, Increases Comfort

Keyboards, pointing devices, or working surfaces that are too high or too low can lead to awkward wrist, arm, and shoulder postures. For example, when keyboards are too low you may type with your wrists bent up, and when keyboards are too high, you may need to raise your shoulders to elevate your arms. Performing keying tasks in awkward postures such as these can result in hand, wrist, and shoulder discomfort.

Proper posture alignment means that your elbows should be about the same height as the keyboard and hang comfortably to the side of the body. Shoulders should be relaxed, and wrists should not bend up or down or to either side during keyboard use.

A keyboard tray may be needed if the work surface or chair cannot be properly adjusted. The keyboard tray should:

  • Be adjustable in height and tilt,
  • Provide adequate leg and foot clearance, and
  • Have adequate space for multiple input devices (for example, a keyboard and pointer/mouse).
