E. The Symptoms of Work-Related Hand Pain

Narrator: This is Science Today. About one out of five people who spend lots of time on computers will develop hand or arm pain which will at some point affect their work or home life. David Rempel, director of the University of California's Ergonomics Program, says brief episodes of pain can usually be relieved by taking breaks and adjusting workstations.

Rempel: But we want the person to pay attention to those aches and pains that last for longer time periods - especially if they last into the night and are with the person the next morning when they go back to work. Or if they recur, they keep occurring every week - especially at the end of the week, Thursdays and Fridays.

Narrator: Over the years Rempel says hand pain, including carpal tunnel syndrome, have been on the rise.

Rempel: It's clearly tied to the issue of more and more people using computers more and more hours of the day - both at work and at home. And once the pain begins to develop, if it's not immediately attended to, it can get worse and worse.
