Poor
ergonomic posture and positioning can
lead to pains in shoulders, elbows,
forearms, wrists and hands. Continuous typing on a computer
keyboard that is not done ergonomically forces the wrist
back during typing. Such wrong
positioning can
lead to
Carpal Tunnel Syndrome (CTS) and other
Repetitive Stress Injuries (RSI).
Many people type on keyboards that are
placed on their desk surface. If the
desk surface is not adjusted to the
proper height, however, the arm and hand
muscle positioning are placed in in
appropriately for long term typing, and
nerves may be compressed. Neck and
shoulder positioning is also strained. The best posture is achieved when
the keyboard is below seated elbow
height, a position that can be created
by using an articulating keyboard tray
with a negative tilt platform which
tilts down and away from the user. This
places the hands in a neutral posture,
and arms, shoulders,
neck and back can relax. |

Following these
guidelines help to establish an
ergonomic computer workstation.
(Much
of the information listed below
is taken
from recommendations by the
Department of Health and Human
Services CDC, Center for Disease
Control):
-
Adjust your chair
height and position so your feet rest flat on the
floor or add a footrest to
compensate for a higher chair.
(If your chair is set too high,
your leg weight is pulled
downward to reach the floor,
creating strain on leg, hip, and
back muscles.)
-
When adjusting your chair
height, your
arms should be comfortable at your side
forming a 90° angle with your
upper arms.
-
Your chair back should
have a lumbar support to support
the natural inward curve of your
lower back. It is also important
that you not stay sitting in
one static position for
extended periods of time,
but alternate between
sitting and standing (take
micro-breaks to move around
and stretch).
-
Adjust the keyboard height so
that your shoulders can relax
and your arms rest at sides. An articulating keyboard tray is
often necessary to accommodate
proper height and distance,
unless you are working at a
computer workstation that
allows easy height
adjustment.
-
Position the keyboard directly
in front and close to you so you
don't have an excessive reach.
-
Your
forearms should be parallel to
the floor (90° angel at elbow)
-
The
mouse should be placed adjacent
to the keyboard and at the same
height, or above, the keyboard.
-
Use a negative tilt
keyboard to position your
wrists straight while typing for
ergonomic keyboarding.
-
If
you mouse slides off at this
tilted angle, select a tray that
has a separately adjustable
mousing surface or one that has
a mouse retention edge.
-
Adjust your articulating keyboard
arm mechanism so that it
doesn't bump your
knees under the work surface.
-
Avoid extended and elevated
reaching for your keyboard or
mouse. Set up your desk
accessories to
keeping the back of your wrist
in a neutral position.
-
Do
not rest your hand on the mouse
when resting - rest your hands
in your lap when not working.
-
A
padded wrist rest will help you
to keep your wrist in a straight
and neutral position while
typing and keep your arms off
the sharp edges of the work
surface.
-
Do
not rest your wrists or hands on
a palm or wrist rest when you
are keyboarding. These
rests are designed to provide
support only during breaks.
-
Press the keys gently and
don't hold them down for
long periods.
-
Keep
your shoulders, arms, hands and
fingers relaxed.
