With the introduction of VDTs many office employees became part of a man-machine system with close physical binding to the workstation. Constrained postures associated with muscle fatigue and sometimes with impairments involving joints or tendons can occur. Field studies revealed a certain incidence of physical discomfort in the neck-shoulder-arm-hand area. These troubles may also occur in other strenuous office jobs. An increased incidence of physical discomfort'and medical findings is observed when keyboard levels are too low, when forearm and wrists cannot rest on an adequate support and when the design of the keyboard itself is too high. A study of preferred settings and postures at adjustable VDT workstations under practical conditions revealed the need for relatively wide ranges of adjustable dimensions. The operators prefer postures similar to those of car drivers: they lean backwards with upper arms kept higher than expected and slightly opened elbow angles. Recommendations are drawn from these studies for the proper design of VDT workstations concerning the ranges of adjustability, the leg room and the chair. |
