Forearm Pads Help Computer Workers

California researchers find providing forearm support during computer work is an effective tool to prevent musculoskeletal disorders.

"Based on this study, it is in the best interest of the company and the employees to provide forearm supports and training," said lead author Dr. David Rempel, director of the ergonomics program at San Francisco General Hospital and professor of medicine at the University of California, San Francisco.

Musculoskeletal disorders of the neck, shoulders and arms are a common occupational health problem for individuals involved in computer-based work, according to Rempel. One of the most common injuries is to the wrist, with either tendinitis or carpal-tunnel syndrome.

A one-year study evaluated the effects of two workstation interventions on the musculoskeletal health of call center employees -- using a padded forearm support -- commonly called an arm board that attaches to the top front edge of the work surface -- and a trackball.

The study, published in The British Journal of Occupational and Environmental Medicine, found the arm boards reduced the risk of incidence of neck and shoulder disorders by nearly half, but the trackball intervention had no effect on right upper extremity disorders.

The researchers calculated a company could get a full return for costs within 11 months of purchase, which leads to better retention of company employees.
