Fatigue of workers is a complex phenomenon resulting from various factors in technically innovated modern industries, and it appears as a feeling of exhaustion, lowering of physiological functions, breakdown of autonomic nervous balance, and decrease in work efficiency. On the other hand industrial fatigue is caused by excessive workload, remarkable alteration in working posture and diurnal and nocturnal rhythms in daily life. Working modes in modern industries have changed from work with the whole body into that with the hands, arms, legs and/or eyes which are parts of the body, and from physical work to mental work. Visual display terminal (VDT) work is one of the most characteristic jobs in the various kinds of workplaces. A large number of fatigue tests have already been adopted, but it is still hard to draw a generalized conclusion as to the method of selecting the most appropriate test battery for a given work load. As apparatus for fatigue measurement of VDT work we have developed VRT (Visual Reaction Test) and the Portable Fatigue Meter. Furthermore, we have presented immune parameters of peripheral blood and splenic T cells for physical fatigue.
工人疲劳是技术创新的现代工业中多种因素导致的复杂现象，表现为疲惫感、生理功能下降、自主神经平衡失调以及工作效率降低。另一方面，职业疲劳是由工作量过大、工作姿势显著改变以及日常生活中的昼夜节律引起的。现代工业的工作模式已从全身工作转变为使用身体的手、臂、腿和/或眼睛进行工作，从体力劳动转变为脑力劳动。视觉显示终端（VDT）工作是各类工作场所中最具代表性的工作之一。已经采用了大量的疲劳测试，但对于给定工作负荷选择最合适测试组合的方法，仍然难以得出一般性结论。作为VDT工作疲劳测量的仪器，我们开发了视觉反应测试（VRT）和便携式疲劳计。此外，我们还提出了身体疲劳外周血和脾脏T细胞的免疫参数。
