The introduction of adjustable workstations for keyboard operators has been widely recommended to eradicate constrained working postures leading to the development of musculoskeletal disorders. A questionnaire evaluating the use of adjustable workstations was analyzed for 514 keyboard operators. Anthropometric dimensions and workstation settings were measured for 15 operators. There was no difference between sufferers and nonsufferers of overuse injury on the basis of adjustability of their equipment. However, sufferers were less satisfied with their equipment and there was evidence that inappropriate postures were being adopted. The availability of adjustable equipment per se does not necessarily solve the problem. The design of the equipment must be based on suitable anthropometric data and operators must be trained in the correct use of the equipment. The results of this study indicate a perceived need for training and/or information on workstation adjustment among operators, with a preference for information that is supplied verbally, rather than in literature form.
为消除导致肌肉骨骼疾病的受限工作姿势，已广泛建议为键盘操作员引入可调节工作站。对一份评估可调节工作站使用情况的问卷进行了分析，涉及514名键盘操作员。对15名操作员测量了人体尺寸和工作站设置。就设备的可调节性而言，过度使用损伤患者和非患者之间没有差异。然而，患者对其设备的满意度较低，并且有证据表明他们正在采用不适当的姿势。可调节设备本身的可用性不一定能解决问题。设备的设计必须基于合适的人体测量数据，并且必须对操作员进行正确使用设备的培训。本研究结果表明，操作员认为需要接受有关工作站调整的培训和/或信息，并且更喜欢以口头形式提供的信息，而不是文献形式的信息。
