The monitor should be adjusted so that the top of the screen is slightly below eye level. It’s best that armrests only be used when not typing, to help maintain proper body alignment. Adjust the armrests so the lower arms rest parallel to the floor. It also helps lift the thighs slightly for better circulation and automatically tilts the body slightly away from the computer. Allowing about 3 inches between the back of the knees and the front edge of the chair seat is ideal to help maintain proper circulation in the legs.A foot stool is very helpful when the feet don’t quite reach the ground. This not only helps with back support, but stability as well. The height should be adjusted so that a user’s arms are bent at a 90° angle or greater when sitting at the desk with both hands on the keyboard. Feet should be flat on the ground, or on a foot stool, with thighs parallel to the floor. The best place to start is with the desk chair. The easiest way to avoid these injuries is to design your workspace to be as ergonomic as possible and take regular breaks as you work to avoid repetitive movements. For a person who tends to slouch or lean towards the monitor, back and neck injuries are another concern. Treatments involve everything from splints to expensive surgery, and this is only one of the likely injuries to occur from poor posture and ergonomics. In some cases, the pain can even travel up the arm and into the shoulder. This can result in tingling, pricking, numbness, pain in the hands or wrists, and loss of grip strength. Carpal Tunnel Syndrome occurs when compression at the wrist causes pressure on the median nerve. One of the most common injuries caused by improper ergonomics is Carpal Tunnel Syndrome.

Considering that the average person spends about 8 hours a day in front of a computer, making a few adjustments to a computer desk setup can have a huge impact on both physical comfort and typing speed.

Good ergonomics increase typing speed by achieving a more efficient positioning for typing movements that requires less motion to reach each key. Desk ergonomics are important to help prevent physical fatigue and the injuries that result from repetitive movements.
