Department: DEA
A chair that undulates, a mouse that vibrates, a monitor suspended over a desk on a movable arm. These are some of the kinds of newfangled ergonomic products that Alan Hedge, international authority on office ergonomics, studies to see if they can prevent repetitive motion injuries among the estimated 100 million people who now use computers in the United States.
"One-third to one-half of all compensatory injuries are repetitive-motion injuries associated with office-type work," says Hedge, professor of design and environmental analysis in Cornell's College of Human Ecology.
