HEALTH WARNING
Use of a keyboard or mouse may be linked to serious injuries or disorder s.
When using a computer, as with many activities, you may experience occasional discomfort in your
hands, arms, shoulder s, neck, or other parts of your body. However, if you expe rience symptoms such
as persis tent or recurring discomfor t, pain, throbbing, aching, tingling, numbness, burning sensation,
or stiffness, DO NOT IGNORE THESE WARNING SIGNS. PROMPTLY SEE A QUALIFIED HEALTH
PROFESSI ONAL, even if s ymptoms occur when you are not working at your computer. Symptoms like
these can be associated with painful and sometimes permanently disabling injuries or disorders of the
nerves, muscles, te ndons, or othe r parts of the body. These musculoskeletal disorders (MSDs) include
carpal tunnel syndrome, tendonitis , tenosynovitis, and other conditions.
While rese archers are not yet able to answer many questions about MSDs, there is general agreement
that many factors may be linked to their occurrence, including: overall health, stress and how one
copes with it , medical and phy sical conditions, and how a person positions and uses his or her body
during work and other activities (including use of a keyboard or mouse). The amo unt of time a person
performs an activity may also be a factor.
Some guidelines that may help you work more comfor tably with your computer and possibly reduce
your risk of experiencing an MSD can be found in the “Hea lthy Computing Guide” installed with this

If you have questions about how your own lifesty le, activities, or medical or physical condition may be
related to MSDs, see a qualifie d health professional.
