Hand and Arm Position and Motion
You can prevent straining of your arms, wrists, and hands by using natural, comfortable motions while working at
the computer. Refer to the illustrations in this section for examples of correct and incorrect positions of arms, wrist,
and hands.
Follow these guidelines when working at the computer:
• When typing, your forearms and wrist should be level and parallel to the floor.
• Keep your elbows in a relaxed position near your body. Your elbows may lightly touch your sides, but don’t
press them tightly against your body.
• When using a keyboard, mouse, or other input devices, keep your wrists in a natural, straight position. Avoid
bending, arching, or angling your wrist.
• If you use a palm rest, use it only briefly for resting. Do not use a palm rest, or rest your hands on the table,
while you are typing.
• Pay particular attention to keeping your thumbs and fingers in a relaxed, natural position.
• Use the minimum amount of force that is needed to push down the keys. Avoid banging on the keys using
more force than is required.
• Hold the mouse with a relaxed hand. Do not grip the mouse tightly.
• Use your whole arm to move the mouse
