This study focused on developing a new approach to seated work positions was conducted on 67 office workers who use a Visual Display Terminal (VDT) as a major function of their working day. Muscle tension was measured by surface electromyography (sEMG) while participants were asked to adopt 4 selected working postures. Pain was measured before and after ergonomic intervention on the Nordic scale, which was modified for this study. Adjustable workstations were used to place participants in desired positions during the clinical testing sessions and the extended intervention period. Results indicate the effects of this ergonomic intervention may have positive effects on muscle tension and pain, significant enough to encourage employers to implement training and workstation modifications following these guidelines.
这项针对67名主要在工作日使用视觉显示终端（VDT）的办公室职员开展的研究，重点是开发一种新的坐姿工作方法。在参与者采用4种选定的工作姿势时，通过表面肌电图（sEMG）测量肌肉张力。在进行人体工程学干预前后，使用针对本研究进行了修改的北欧量表测量疼痛程度。在临床测试阶段和延长的干预期内，使用可调节工作站将参与者置于所需位置。结果表明，这种人体工程学干预可能会对肌肉张力和疼痛产生积极影响，其影响程度足以鼓励雇主按照这些指导方针开展培训并对工作站进行改造。
