VDT work duration and musculoskeletal discomfort.

Musculoskeletal discomfort, work position, and job stress factors were compared in government office workers grouped according to whether they used video display terminals more or less than 4 hours per day. The results of this study suggest that limits on VDT use to less than 4 hours per day do not necessarily protect against health problems. The occupational health nurse's role in preventive measures useful for alleviating the musculoskeletal health problems of office work are discussed.
