摘要: | 現代人依賴電腦及其周邊產品的程度與日俱增,不當的使用姿勢與過長的使用時間均會造成上肢肌肉過度緊張,進而導致各種上肢肌肉骨骼不適的發生。國內外有不少文獻探討傳統滑鼠與人體工學滑鼠對肌肉負荷之影響,但少有文獻針對滑鼠之擺設位置做一個綜合性的探討。
本研究旨在透過肌電訊號分析,探討滑鼠擺設在三種高度、三種前後位置以及四種傾斜平面時,對上肢肌肉活性之影響。二十位受試者自願參與本研究,每位受試者利用滑鼠進行複製文件之工作,並以表面肌電儀紀錄十條上肢肌肉在動作過程中之肌肉活性。從中找出最符合人體工學的滑鼠擺設位置,降低電腦工作者使用滑鼠時之肌肉負荷,以減少慢性病變之發生。 Human relies on computers for their daily work much more than before. Improper posture and prolonged working may cause hypertension of the upper extremity muscles, leading to musculoskeletal disorders (MSDs) of the upper extremity. There were many literatures aimed on investigating the relationship between the usage of traditional and ergonomic computer mouse. However, it was rarely reported the general effect on muscle activity in different mouse positions. The purposes of the current study were to investigate the effects of different computer mouse positions on upper extremity muscle activities using electromyography analysis. Twenty subjects participated in this study. The activities of ten upper extremity muscles during computer mouse usage were collected in three heights, three forward/backward positions and four slanted surface. The results of this study will be helpful for computer users to decide the optimum position to use computer mouse and reduce MSDs. |
