Select the symptom you are having to view possible solutions:

Eyestrain, which includes dry eyes, blurred vision, bloodshot eyes and sore, tired eyes

Neck and shoulder strain

Arm and shoulder strain

Wrist pain, tingling and numbness in the fingers and pain extending up the arms

Lower back pain

Leg strain or pain


Symptoms: Eyestrain, which includes dry eyes, blurred vision, bloodshot eyes and sore, tired eyes


  1. Position the monitor18"-28" from the eyes (approximately an arms length).
  2. Position the monitor at a right angle to the window to minimize glare and reflection.
  3. Tilt the monitor so that light sources do not reflect onto the screen.
  4. Consider the use of an Anti-Glare Filter to minimize glare and reflection or a monitor hood to block out a direct light source.
  5. Adjust the brightness and contrast buttons on your monitor to maximize crispness and clarity. The use of a separate Task Light will provide light where needed for reading and writing.
  6. Lower the lighting level when working on the computer (approximately half of that used for reading and writing).
  7. Locate documents at the same height of the monitor or in-line to the monitor to minimize eye refocusing. Consider the use of a Document Holder to position your reference material as close to the monitor screen as possible.
  8. Blink frequently to moisturize the eyes.
  9. Take periodic eye rest breaks such as focusing on a distant object and cupping the eyes.

Symptoms: Neck and Shoulder strain


  1. Position the monitor in a straight-ahead position rather than to the side. This will encourage a neutral head and neck position.
  2. Position the top of the monitor at or slightly below eye level so that the head and neck remain in a neutral position. The use of Monitor Risers offer a quick and easy way to add height to your computer monitor.
  3. Position the document at the same height and distance to the monitor or between the keyboard and the bottom of the monitor for in-line viewing. In-line Document Holders are recommended for the best results.
  4. Avoid cradling the telephone headset between the head and shoulder. Consider the use of a telephone headset or speakerphone.
  5. Posture follows the eyes; position reading material on an inclined surface with the use of a slant board to encourage an upright upper body posture.

Symptoms: Arm and Shoulder strain


  1. Position frequently used items within your 'near reach zone' as to minimize arm extension and shoulder strain.
  2. Position yourself close enough to the keyboard and mouse so that your elbows are by your side and arm extension minimized. The use of a Keyboard Arm & Platform may provide the height, angle and distance adjustments needed.
  3. Adjust chair height or worksurface height (use Desk Risers or an Adjustable Tables) for the task being performed: The arms should be at a comfortable open angle (100° to 110°) while keying. The reading and writing surface is typically 1 1/2" - 2" higher than keying height, thereby allowing the forearms to rest comfortably on the work surface and back and shoulders in a comfortable position. Forearm Supports can also be used to provide postural support and freedom of movement while performing repetitive motion tasks.

Symptoms: Wrist pain, tingling and numbness in the fingers and pain extending up the arms


  1. Check your keying and mousing position so that your shoulders are relaxed, arms at a slightly open angle (100° to 110°), elbows by your side, and the wrists straight with fingers arched while keying. A Keyboard Arm & Platform will aid in this adjustment. When positioned properly, the keyboard should be placed above laptop level to allow your arms to tilt downward while leaving your elbows at a comfortable open angle (100° to 110°). A slightly negative keyboard tilt will encourage a neutral wrist position. To avoid a positive tilt, make sure the legs on the back of the keyboard are in a lowered position.
  2. Adjust your chair height or keying surface to achieve the correct keying position. The keying surface can be adjusted by using Desk Risers, Keyboard Arm & Platform or Adjustable Tables.
  3. Position the mouse on the same surface and directly adjacent to the keyboard. For those that do not use the 10-key frequently, a Mouse Bridge offers a low cost solution to positioning the mouse directly over the 10-key portion of the keyboard, thereby minimizing arm extension while mousing.
  4. Take periodic rest breaks and stretching exercises to minimize extended periods of repetitive keying and mousing tasks. Stretch Break Software is available to remind you to take periodic breaks by performing a series of low-impact stretches.
  5. Arch fingers and float hands across the keys while keying. Avoid planting the hands and wrists on a Wrist Rest while keying.

Symptoms: Lower Back pain


  1. If using an adjustable chair, position the backrest so the lower back is supported. If using a non-adjustable chair, then consider the use of a Back and Seat Cushion for support as needed.

Symptoms: Leg strain or pain


  1. Lower chair height or provide a Footrest so that feet are resting comfortably and the legs are at a right angle with the knees slightly lower than the hips.
