Keyboard and Mouse Devices: Health Warning

Use of a keyboard or mouse may be linked to serious injuries 

or disorders. As in many activities, when using a computer 

you may experience occasional discomfort in various parts 

of your body. However, do not ignore symptoms such as 

persistent or recurring discomfort, pain, throbbing, aching, 

tingling, numbness, burning sensation or stiffness. Promptly see 

a qualified doctor, even if symptoms occur when you are not 

working at your computer.
There is general consensus among researchers that there may 

be many factors linked to the occurrence of these symptoms, 

including overall health, stress, physical condition and how 

a person positions and uses his or her body during work and 

other activities (including the use of a keyboard or mouse). The 

amount of time a person spends performing an activity may 

also be a factor.
If you have questions about how your own lifestyle, activities 

or physical condition may be related to these symptoms, see a 

qualified health professional.
