Concern that keyboard design may cause computer users to develop pain in the hands, wrists and arms--a condition known as carpal tunnel syndrome--has led to the marketing of a new generation of keyboards. But are these "ergonomically correct" keyboards more beneficial than standard keyboards?

A National Institute for Occupational Safety and Health study suggests they aren't. Researchers studied 50 female clerical workers who typed for two days on either a conventional keyboard or one of three alternative-design keyboards with a split-configuration (keys for the left and right hands on separate units). The workers reported only a low level of fatigue and discomfort, and there was no difference between keyboard designs. The study concluded that keyboard design may not be a significant factor affecting user comfort.

To prevent carpal tunnel syndrome, the American Physical Therapy Association recommends the following:

• keep your wrists straight when typing
• limit the motion of your wrists
• avoid resting your wrists on the desktop
• use an adjustable keyboard tray to put the keyboard at the proper height
• take frequent breaks
• perform stretching exercises on your hands
