视屏显示终端操作者姿势工效学调查

Study of posture ergomoics of VDT operators.

对143名VDT操作者进行初态姿势观察,择其中40名进行跟班动态观察一工作日,发现姿势类型主要有六种,且以第一种为多,姿势变抉间隔时间以第四种为长。提示VDT操作者姿势和有关工效学数据不尽理想,这可能由于桌椅不配套。使用固定式桌子,建议使用可调式桌椅。

Six types of posture was found by observing the initiating posture of 143 VDT operatots and by whole shift dynamic observation of posture among 40 selected VDT operators. The initiating posture appeared to be dominant among those six types (ie. taking a whole seat, upright trunk, attaching to chair back with waist). The longest interval for changing posture was found to be the fourth posture (ie. taking a half seat, trunk inclining forward, without attachment to the chair back with waist). It was suggested that VDT operators, posture and indices of related ergonomics were not satisfied. The reason might be due to unfitted desk chair and fixed desk. It was also suggested that VDT operators should use regulatable desk and chair.
