3. Ergonomics is a discipline that involves
arranging the environment to fit the
person in it. When ergonomics is
applied correctly in the work
environment, visual and
musculoskeletal discomfort and fatigue
are reduced.

4. Other Issues
Another concern for computer
users is their vision. Staring at a
computer monitor for hours on
end can strain the eyes, resulting
in eyestrain and headaches.
Remember to take breaks at
regular intervals.

5. Health Issues
Repetitive motion injuries can cause
employee injuries. These injuries are
caused by excessive and repeated
physical stress on the hands, wrists,
elbow, shoulders, neck and back

6. What is CTS
 Carpal tunnel syndrome or CTS is a painful progressive
condition caused by squeezing of a key nerve in the wrist. It
occurs when the median nerve, which runs from the forearm
into the hand, becomes pressed or squeezed at the wrist. This
causes pain, weakness or numbness in the hands, wrists and
arms.
 The risk of developing carpal tunnel syndrome is especially
common in those performing assembly line works or repetitive
computing.

8. What is RSI
 RSI is an umbrella term for various types of pain
symptoms in the neck, shoulders, arms, wrists and
hands, and sometimes even in the legs.
 RSI occurs from chronically overstrained muscles
cause by repeated physical movements such as
clicking on the mouse or rapid touch typing
whereby no or little variation in the working
posture is possible.
 A workstation which cannot be optimally adapted
to the persons measurements can cause RSI.

9. Avoiding RSI
A high level of work pressure can often
lead to extra-tensed muscles in the neck
and shoulder so it is essential to take
hourly breaks and try to interchange
repetitive tasks with other tasks.
 A well designed work station is essential to
good health when using computers.

10. Preventing and
Minimising injuries.
• Take short breaks hourly.
• Every 5 minutes, look away from the
screen and focus your eyes on
something in the distance.
• Make sure your work station is
adjusted to suit your own
requirements.
• Work in a well-lit environment.
