Hand-operated tools transmit a high magnitude of vibration exposure to the hand-arm system that causes occupational diseases. The health effects caused in various countries for the past years due to usage of hand tools are necessary to identify the occupational disorders. Researchers have conducted various studies on biological effects, hand-transmitted vibration exposure and biodynamic responses throughout the years. This article goes over each of these studies in detail, as well as identifying areas where more research is needed. The majority of studies deal with the following topics: general guidelines for hand-transmitted vibrations; assessment techniques of vibration exposure; hand-tool evaluation methods; influence of hand-tool design to overcome the biomechanical effects; and finite element modelling for quantifying vibration exposure. In response to this, understanding the biodynamic behaviour of the hand-arm system is useful for better ergonomic intervention in hand tools to reduce fatigue and increase comfort.
手动工具会向手臂系统传递高强度的振动，从而引发职业病。过去几年里，各国因使用手动工具而产生的健康影响对于识别职业疾病很有必要。多年来，研究人员针对生物效应、手部传递的振动暴露以及生物动力学反应开展了各类研究。本文详细阐述了这些研究，并指出了仍需进一步研究的领域。大多数研究涉及以下主题：手部传递振动的一般准则；振动暴露的评估技术；手动工具评估方法；克服生物力学效应的手动工具设计影响；以及用于量化振动暴露的有限元建模。对此，了解手臂系统的生物动力学行为有助于对手动工具进行更好的人体工程学干预，以减轻疲劳并提高舒适度。
