86 Setting up a healthy work environment
Making your computer work for you
Computers are everywhere. More and more people sit at computers
for longer periods of time. This appendix explains how to set up your
computer to fit your physical needs. This information is based on
ergonomics — the science of making the workplace fit the needs of the
worker.
Some nerve, tendon, and muscle disorders (musculoskeletal
disorders) may be associated with repetitive activities, improper work
environments, and incorrect work habits. Examples of
musculoskeletal disorders that may be associated with certain forms
of repetitive activities include: carpal tunnel syndrome, tendinitis,
tenosynovitis, de Quervain’s tenosynovitis, and trigger finger, as well
as other nerve, tendon, and muscle disorders.
Although some studies have shown an association between increasing
hours of keyboard use and the development of some musculoskeletal
disorders, it is still unclear whether working at a computer causes
such disorders. Some doctors believe that using the keyboard and
mouse may aggravate existing musculoskeletal disorders.
Some people are more susceptible to developing these disorders due
to pre-existing conditions or psychosocial factors (see “Pre-existing
Conditions and Psychosocial Factors” later in the appendix).
To reduce your risk of developing these disorders, follow the
instructions in this appendix. If you experience discomfort while
working at your computer or afterwards, even at night, contact a doctor
as soon as possible. Signs of discomfort might include pain,
tenderness, swelling, burning, cramping, stiffness, throbbing,
weakness, soreness, tingling and/or numbness in the hands, wrists,
arms, shoulders, neck, back, and/or legs.
