视频显示终端（VDT）操作员（n = 150）在编辑部的一个大都市报纸参加了一项研究，每天的肌肉骨骼症状。与VDT工作站和心理社会工作因素相关的工作姿势也被调查，以确定其对上肢疼痛、麻木和僵硬严重程度的影响，并使用了一个具有代表性的子样本（n = 70）。自我报告的措施包括Karasek的工作内容工具和作者设计的工作人际关系清单。使用与Sauter等人[1991]报告的技术类似的技术对工作姿势进行独立观察。59%（n = 88）的受访者报告了上周的疼痛，28%（n = 42）的受访者按症状标准分类为可能患有肌肉骨骼疾病。每天使用VDT的时间越长，工作中的决策自由度越小，是潜在的肌肉骨骼CTD的重要危险因素。头部旋转和相对键盘高度与肩部、颈部和上背部更严重的疼痛和僵硬显著相关。较低水平的同事支持与更严重的手和手臂麻木有关。然而，对于肩部、颈部、上背部以及手部和手臂区域，相对键盘和座椅靠背高度对症状严重程度的贡献被心理工作负荷、决策自由度以及员工与主管的关系所改变。这些结果的替代解释进行了讨论。(C)1994 Wiley-Liss，Inc.
Video display terminal (VDT) operators (n = 150) in the editorial department of a large metropolitan newspaper participated in a study of day-to-day musculoskeletal symptoms. Work posture related to the VDT workstation and psychosocial work factors were also investigated for their contributions to the severity of upper body pain, numbness, and stiffness using a representative subsample (n = 70). Self-report measures included Karasek's Job Content Instrument and the author-designed Work Interpersonal Relationships Inventory. Independent observations of work posture were performed using techniques similar to those reported by Sauter et al. [1991]. Pain during the last week was reported by 59% (n = 88) of the respondents, and 28% (n = 42) were categorized by symptom criteria potentially to have musculoskeletal disorders. More hours per day of VDT use and less decision latitude on the job were significant risk factors for potential musculoskeletal CTDs. Head rotation and relative keyboard height were significantly related to more severe pain and stiffness in the shoulders, neck, and upper back. Lower levels of co-worker support were associated with more severe hand and arm numbness. For both the region of the shoulders, neck, and upper back and the hand and arm region, however, the contributions of relative keyboard and seat back heights to symptom severity were modified by psychological workload, decision latitude, and employee relationship with the supervisor. Alternative explanations for these findings are discussed. (C) 1994 Wiley-Liss, Inc.
