[Ergonomy and videoterminals].

After defining some concepts relative to ergonomy and videoterminals (VDT), the paper describes the main health risks for VDT workers (visual, muscle-skeletal and stress disorders). The ergonomic requirements established by the Italian legislation for VDT work are then examined, including illumination, the working environment, the working desk and seat, the video-screen, the keyboard, the upper body position, pauses and physical exercise, training and information. Recent regulations (in particular the law 422/2000) on the sanitary surveillance of VDT workers are finally reported.
