良好的工作位置
为了了解设置计算机工作站的最佳方法,了解中性身体定位的概念是有帮助的。这是一个舒适的工作姿势,你的关节自然对齐。以中立的姿势与身体一起工作可以减轻肌肉、肌腱和骨骼系统的压力和紧张,并降低你患肌肉骨骼疾病(MSD)的风险。以下是在电脑工作站工作时尝试保持中性身体姿势的重要注意事项:
手、手腕和前臂笔直、对等,与地板大致平行。
头部水平,面向前方,平衡。一般来说,它与軀托对线。
肩膀放松,上臂正常垂在身体两侧。
肘部靠近身体,弯曲90到120度。
脚完全由地板支撑,或者如果桌子高度无法调节,可以使用脚踏板。
垂直坐着或稍微向后倾斜时,背部得到适当的腰部支撑。
大腿和臀部被支撑,通常与地板平行。
膝盖和臀部的高度差不多,脚稍微向前。
Good Working Positions
To understand the best way to set up a computer workstation, it is helpful to understand the concept of neutral body positioning. This is a comfortable working posture in which your joints are naturally aligned. Working with the body in a neutral position reduces stress and strain on the muscles, tendons, and skeletal system and reduces your risk of developing a musculoskeletal disorder (MSD). The following are important considerations when attempting to maintain neutral body postures while working at the computer workstation:
Hands, wrists, and forearms are straight, in-line and roughly parallel to the floor.
Head is level, forward facing, and balanced. Generally it is in-line with the torso.
Shoulders are relaxed and upper arms hang normally at the side of the body.
Elbows stay in close to the body and are bent between 90 and 120 degrees.
Feet are fully supported by the floor or a footrest may be used if the desk height is not adjustable.
Back is fully supported with appropriate lumbar support when sitting vertical or leaning back slightly.
Thighs and hips are supported and generally parallel to the floor.
Knees are about the same height as the hips with the feet slightly forward.
