The primary purpose of this study was to compare the posture and muscle control patterns between male and female computer users with musculoskeletal symptoms. Forty computer users were recruited. Each subject performed a preferred speed typing, a fast speed typing, and a repetitive mouse task. The independent variables were gender, typing speed, and time. There were significant differences between genders for head and neck flexion angles when they were performing the preferred speed typing task. Significant differences between genders were also found for upper extremity angles when they were performing the repetitive mouse task. Male computer users had a smaller root mean square of the right extensor digitorium than females. In general, postural differences were significant between genders, even when the subjects' table and chair were adjusted to meet their anthropometry. Our results suggest that modifications of the computer working environment may be different between genders.
本研究的主要目的是比较有肌肉骨骼症状的男性和女性电脑使用者的姿势和肌肉控制模式。招募了 40 名电脑使用者。每位受试者执行了一个偏好速度打字、一个快速速度打字和一个重复性鼠标任务。自变量为性别、打字速度和时间。当进行偏好速度打字任务时，男女之间的头颈部弯曲角度存在显著差异。当进行重复性鼠标任务时，男女之间的上肢角度也存在显著差异。男性电脑使用者的右侧伸指总肌的均方根值小于女性。总的来说，即使受试者的桌椅根据他们的人体工程学进行了调整，性别之间的姿势差异仍然很明显。我们的研究结果表明，电脑工作环境的修改可能因性别而异。
