B. Workers Need To Give Ergonomics A Chance

Narrator: This is Science Today. A new study has found ergonomically correct tools - such as computer keyboards - benefit workers a little later than previously thought. David Rempel, the director of the University of California's Ergonomics Program, says this study, which was done in connection with researchers at the Lawrence Livermore National Laboratory, concluded that people using such tools shouldn't decide whether they work based on immediate feedback.

Rempel: The value of a study like this is, for the first time it looks like a relatively simple intervention - making a small change in the keyboard which doesn't significantly impact the cost of the keyboard - might have some health value.

Narrator: While their work did find ergonomically correct keyboards very beneficial, Rempel recommends other activities as well.

Rempel: Limit the number of hours on the computer, make sure they're adequate work breaks and make sure that the whole workstation is set up properly for the person's body size.
