This is one example of an ergonomically correct workstation. Some
people would be more comfortable with slight adjustments such as tilting the
keyboard up a bit or removing the armrests from the chair, but this picture
shows many of the important pieces of a good workstation.
- The top of the monitor screen is at eye level.
- A telephone headset helps you to avoid awkward positions while talking and doing
other tasks, such as typing.
- A wrist pad at
the bottom of the keyboard helps keep the wrists in a neutral, almost straight
position during brief rests from typing. Wrist pads are not designed to be used
while you type, but some people find the pads helpful even when they are using
their keyboard or mouse. When you type or use your mouse, try raising your
forearms a little so your wrists are in a neutral position and your arms and
hands can move freely. If you have arm rests on your chair, you may be able to
adjust them so your forearms are parallel to the floor and your wrists are
neutral. You may want to alternate between resting your wrists on the pads and
raising them up. If you use a wrist pad, it's best to rest your palm or the
heel of your hand on the support, rather than your wrist.
- A footrest raises the feet to reduce
pressure on the lower back.
- Armrests are
adjusted so that the elbows are close to the side of the body and bent at an
angle between 90 and 100 degrees.
- An adjustable chair has a height adjustment to allow the feet to rest on the floor or
a footrest; the back of the chair also adjusts for different positions.
Sitting with the ears directly above the shoulders, which in turn are
over the hips, helps prevent back strain. Placing a lumbar pillow or roll
against the small of the back provides additional support.
