The number of people who suffer from computer-related injuries has reached epidemic proportions. Today, most of us are so dependent on computers that we are at risk for developing a variety of painful symptoms and disabling conditions.

Computer-related injuries, also called ergonomic disorders, are often caused by poor posture and improper work area arrangements. If left uncorrected, these have the potential for developing into more serious Repetitive Strain Injuries (RSI). Some of the more common of these conditions include Carpal tunnel syndrome, cervical strain, epicondylitis (“tennis elbow”) and tendonitis. Computer-related injuries affect the fingers, hands, wrists and elbows, but they may also involve the neck and back.

Most of these injuries can be prevented by using basic ergonomics. Ergonomics is the study of how people use tools and equipment to do their daily living activities. Better health, safety, productivity, reduction of stress and improving quality of life are examples of ergonomic goals.

Here are some ways you can prevent desktop computer-related and repetitive stress injuries in the workplace:

•  Place the computer monitor directly in front of you. Align yourself with the monitor and keyboard.

• Position the top of the monitor at eye level and about an arm’s length away.

• Use a document holder to place source documents close to the computer screen. Alternate the location of the document holder to avoid concentration of stress on one side of the neck.

• Place the mouse next to the keyboard within comfortable reach. Grip the mouse lightly.

• Maintain a proper posture of a 90-degree angle at the hips and knees while keeping the knees supported by the floor or footrest.

• Gently rest the palms and forearms for long-term keyboard use.

• Adjust keyboard and chair height to keep forearms, wrists and hands in a straight line. The keyboard should fall directly below the hands with the elbows at about 90 degrees.

• Keep shoulders relaxed and elbows close to the body.

• Select a chair that allows clearance behind the knees (seat not too deep).

• Use the backrest of the chair to provide full support, particularly for the lower back.

By giving some thought to being “ergonomically correct,” you can save yourself not only pain, but the time and money expended if you develop a condition that keeps you logged off for weeks or months at a time. As many people have already discovered, working smart when using your computer is just part of living well.
