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 in-
correct work habits. Examples of musculoskeletal disorders that may be as-
sociated 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.
