Articulating Keyboard Trays

For those who do not have the following information, articulating keyboard trays should be adjusted so that the shoulders and elbows hang in a relaxed manner with the wrists aligned with the forearms. If the wrists are not straight, or if the back is bent forward, the angle of the tray should be adjusted. Some trays include padded wrist rests to keep them straight as well.

Unfortunately, extensive use of the keyboard and mouse causes a number of problems in the wrists, elbows, shoulders and hand. Uninterrupted movements of the delicate bones and soft tissues of the hands and wrist can lead to carpal tunnel syndrome. If articulating keyboard trays are not set up properly, people's shoulder and elbow joints can experience forceful exertions and become forced into painful postures for hours.

Articulating Keyboard Trays That Include Mouse Trays

Some trays are large enough to include an area large enough on either side to include mouse pads and the mice themselves. The same ergonomic principles must apply to the use of the mouse as they are to the keyboard. When the mouse is not in use, the hand should be kept at the keyboard or in the lap to aid against needless strain and extension.

Some articulating keyboard trays come included with ergonomic desk packages, while others are built into ergonomic chairs themselves. If a desk does not come built with an articulated tray, one can be bought separately and attached with a few simple tools. Never use the tray as an elbow rest when leaning forward--if you must, pull the chair forward, move the tray and put your weight on the desk itself.
