本研究的主要目的是建立一种替代方法，用于测量手套对圆柱形手柄抓握强度的影响，并量化由于使用典型抗振（AV）手套而导致的强度降低。与先前在特定平面测量握力的研究不同，替代方法测量了垂直于圆柱形手柄的总接触力;总握力定义为受试者以他/她的最大随意收缩（MVC）力量对手柄施加动力抓握时测量的总接触力。本研究中使用了两个内固定圆柱形手柄（30和40 mm）。10名受试者参加了实验。在实验中使用了四种类型的AV手套和两种类型的非AV手套。与徒手试验相比，无论手柄大小如何，四种防震手套中的每一种都使握力降低了29%以上。其中一种非AV手套也大大降低了握力（>= 25%），而另一种手套的握力降低小于10%。手套还影响了圆柱形手柄周围的握力分布模式。结果表明，手套的厚度是与这些影响相关的主要因素之一。与行业的相关性：通常建议使用手套来保持双手温暖和干燥，并保护他们免受许多其他危险，前提是这与安全有效的工具操作一致。然而，使用更厚，更硬的手套，如一些AV手套，可能会用一种健康风险来换取另一种健康风险。了解手套对握力的影响可以帮助工人、管理人员和安全专业人员在工作场所选择和使用手套时做出明智的决定。这些知识也可能导致工作手套的改进。由爱思唯尔公司出版
The major objectives of this study were to establish an alternative method for measuring the effects of gloves on the grip strength applied to cylindrical handles and to quantify the strength reduction due to the use of typical anti-vibration (AV) gloves. Different from previous studies that measure the grip force in a specific plane, the alternative method measures the total contact force normal to a cylindrical handle; the total grip strength is defined as the total contact force measured when a subject applies a power grip to the handle with his/her maximum voluntary contraction (MVC) effort. Two instrumented cylindrical handles (30 and 40 mm) were used in this study. Ten subjects participated in the experiment. Four types of AV gloves and two types of non-AV gloves were used in the experiment. Compared with bare-handed trials, each of the four anti-vibration gloves reduced the grip strength by more than 29%, regardless of handle size. One of the non-AV gloves also largely reduced the grip strength (>= 25%) whereas the grip strength reduction of the other one was less than 10%. The gloves also influenced the grip force distribution pattern around the circumference of the cylindrical handles. The results suggest that the thickness of a glove is one of the major factors associated with these effects.Relevance to industry: Glove use is generally recommended to keep the hands warm and dry and to protect them from many other hazards, provided this is consistent with safe and effective tool operation. However, a user of thicker, stiffer gloves, such as some AV gloves, could be trading one health risk for another. Knowledge of the effects of gloves on grip strength can help workers, managers, and safety professionals make informed decisions about glove selection and use in the workplace. This knowledge may also lead to work glove improvements. Published by Elsevier B.V.
