Office Ergonomics
Office ergonomics concern the physical layout of a work
setting, including how the physical use of the computer
affects the physiological condition of users. The effective
practice of ergonomic principles can reduce the occurrence of
Cumulative Trauma Disorders (CTDs) such as carpal tunnel syndrome
and other causes of tendon inflammation.
Core principles
This website on
office ergonomics training
provides excellent practical information. Below is a list of
major principles and advice from the site.
- Monitor location. Monitor should be at
least 25 inches away and slightly below the eyes (less than 15
degrees).
- Contrast and lighting. The contrast of
black text on white background is good. Direct light on monitor
is bad.
- Activity. Variety of movement is generally
good. Avoid systemic, repetitive activity.
- Neutral position. Frequent position of
joints should generally rest halfway in the joints' range of
motion.
- Emphasis on comfort. Perceived comfort of
user is an important indicator of a setting's ergonomics.
- There is no perfect rule. There are many
exceptions to the common guidelines, particularly for users with
special needs and conditions.
The website provides a helpful checklist for
evaluating the
ergonomics of a work setting.
