• Keep your forearms horizontal with your wrists in a neutral,
comfortable position while using the keyboard, touch pad, track stick,
or external mouse.
• Always use the palm rest with the keyboard, touch pad, or track stick.
Leave space to rest your hands when using an external mouse.
• Let your upper arms hang naturally at your sides.
• Sit erect with your feet resting on the floor and your thighs level.
• When sitting, make sure the weight of your legs is on your feet and not
on the front of your chair seat. Adjust your chair’s height or use a
footrest, if necessary, to maintain proper posture.
• Vary your work activities. Try to organize your work so that you do not
have to type for extended periods of time. When you stop typing, try
to do things that use both hands.
