An articulating keyboard tray can provide optimal positioning of input devices. However, it should accommodate the mouse, provide leg clearance, and have an adjustable height and tilt mechanism. The tray should not push you too far away from other work materials such as your telephone.

Maintain good posture when working.
Sit all the way back in the chair against the backrest. Keep your knees equal to, or lower, than your hips with your feet supported.

Pull up close to your keyboard.

Position the keyboard directly in front of your body.
Determine what section of the board you use most frequently, and readjust the keyboard so that section is centered with your body.

Adjust the keyboard height
so that your shoulders are relaxed, your elbows are in a slightly open position (100° to 110°), and your wrists and hands are straight.

The tilt of your keyboard is dependent upon your sitting position.
Use the keyboard tray mechanism, or keyboard feet, to adjust the tilt. If you sit in a forward or upright position, try tilting your keyboard away from you at a negative angle. If you are reclined, a slight positive tilt will help maintain a straight wrist position.

Wristrests can help to maintain neutral postures and pad hard surfaces.
However, the wristrest should only be used to rest the palms of the hands between keystrokes. Resting on the wristrest while typing is not recommended. Avoid using excessively wide wristrests, or wristrests that are higher than the space bar of your keyboard.

Place the pointer as close as possible to the keyboard.
Your pointing device should be positioned within easy reach. Over-reaching can result in shoulder and/or arm discomfort. If you are reaching out to use your pointer, elevate it on a mouse bridge, platform or small book to bring it within closer reach.

Keep your wrists straight and hands relaxed when using your pointer.
Don't hold the pointer with a tight grip or extend fingers above the activation buttons. Avoid moving the pointer with your thumb or wrist. Movement should originate at your shoulder and elbow.

Keep your elbows in a slightly open angle (100° to 110°) with your wrists in a straight position.
If you sit in an upright position, your keyboard should be placed in a slight negative tilt so that the wrists can be placed in an aligned or neutral position. Your hands should be slightly lower than your elbows with your fingers pointing toward the floor. (Note: If you recline back in your chair, you might not need to tilt the keyboard. Check the alignment of your wrist, and then set the angle of the keyboard as needed. Your sitting posture will affect how you adjust your keyboard and pointing device.)

Work at a reasonable pace and take frequent stretch breaks.
Take 1 or 2 minute breaks every 20-30 minutes, and 5 minute breaks every hour. Every few hours, try to get up and move around.

Use good typing technique.
Float your arms above the keyboard and keep your wrist straight when keying. If you use a wristrest, use it to support your palms when pausing, not while keying.

Hit the keyboard keys with light force.
The average user keys four times harder than necessary.

Limit repetitive motions.
Reduce keystrokes with macros and software programs such as voice recognition. Reduce pointing device movement with scroll locks and keystroke combinations.

Use of non-prescribed medications, or wrist splints, can often be more harmful than helpful.
If you begin to develop symptoms, seek help. Early intervention can prevent future problems.

Your life style and physical fitness affect how you feel at work.
Stay in shape by stretching and exercising regularly.
