Abstract
Recent studies have demonstrated a daily accumulation of eye and musculoskeletal strain in video display terminal (VDT) workers which is not eliminated by the use of high quality workstations or conventional rest break schedules (e.g., Zwahlen et al., 1984; Schleifer and Amick, 1988). These types of observations have prompted calls for limitations on the period of continuous VDT work. For example, the Swedish National Board of occupational Safety and Health has suggested an upper limit of 1-2 hours of continuous VDT work. While the logic for such recommendations is substantial, there has been little empirical study of the effects of increased rest breaks, or shortened work periods, in VDT work. There is, however, an extensive literature on the design of rest break schedules in light, repetitive (industrial) work. This literature has been largely ignored in discussions regarding rest break design in VDT work, but is highly relevant since the tasks studied share common stress factors with VDT work (e.g., constrained static postures and the need for continuous attention).
