A-4 Setting Up a Healthy Work Environment
■
Use armrests or forearm supports to support your fore-
arms. If adjustable, the armrests or forearm supports
should initially be lowered while all the other adjust-
ments discussed in this appendix are made. Once all
these adjustments are completed, raise the armrests or
adjust the forearm supports until they touch the forearms
and allow the shoulder muscles to relax.
ADJUST YOUR INPUT DEVICES
Note the following points when positioning your notebook
computer or any external input devices.
■
Position your keyboard directly in front of you. Avoid
reaching when using your keyboard or mouse.
■
If you use a mouse, position it at the same height as the
keyboard and next to the keyboard. Keep your wrists
straight and use your entire arm when moving a mouse.
Do not grasp the mouse tightly. Grasp the mouse lightly
and loosely.
■
Adjust the keyboard height so that your elbows are near
your body and your forearms are parallel to the floor,
with your forearms resting on either armrests or forearm
supports, in the manner described previously. If you do
not have armrests or forearm supports, your upper arms
should hang comfortably at your sides.
■
Adjust the keyboard slope so that your wrists are
straight while you are typing.
■
Type with your hands and wrists floating above the key-
board. Use a wrist pad only to rest your wrists between
typing. Avoid resting your wrists on sharp edges.
■
Type with your wrists straight. Instead of twisting your
wrists sideways to press hard-to-reach keys, move your
whole arm. Keep from bending your wrists, hands, or
fingers sideways.
