许多国家的健康和安全法规要求处于危险中的工人在工厂环境中穿着安全鞋。这些鞋子通常又重、又硬又不舒服。每天穿着安全鞋会导致足部问题、不适和疲劳，还会导致大量工作日的损失。目前，对于工作活动期间安全鞋鞋垫的生物力学影响的了解非常有限。选取了一家金属加工厂的 17 名工人，对足部状况进行了临床检查。对工人的脚部进行 3D 扫描，了解其足底视图，并根据脚部和安全鞋模型使用图像来设计 34 个定制鞋垫。每位工人对三种鞋垫进行盲测：定制 (CUS)；定制 (CUS)；预制安全鞋（PSS）和现成的（OTS）。在复制典型工作活动的七种运动任务中测量脚到鞋垫的压力分布：单腿和双腿站立；举重；楼梯上升和下降；正常和快速行走。在大多数工作活动中，穿着安全鞋内的 CUS 会导致整个足底区域的压力分布更加均匀。正常行走时前脚的峰值压力在定制鞋垫中最低（CUS 275.9 +/- 55.3 kPa；OTS 332.7 +/- 75.5 kPa；PSS 304.5 +/- 54.2 kPa）。研究发现，正常步行和快速步行是对峰值压力要求最高的活动。穿着安全鞋会导致多个足部区域的足部压力参数升高。与预制的无特征鞋垫相比，使用根据足部形态设计的定制鞋垫有助于降低峰值压力和压力时间积分。 (C) 2016 Elsevier B.V. 保留所有权利。
Health and safety regulations in many countries require workers at risk to wear safety shoes in a factory environment. These shoes are often heavy, rigid, and uncomfortable. Wearing safety shoes daily leads to foot problems, discomfort and fatigue, resulting also in the loss of numerous working days. Currently, knowledge of the biomechanical effects of insoles in safety shoes, during working activities, is very limited.Seventeen workers froth a metalworking factory were selected and clinically examined for any foot conditions. Workers feet were 3D scanned, with regards to their plantar view, and the images used to design 34 custom-insoles, based on foot and safety shoe models.Three insoles were blind-tested by each worker: custom (CUS); prefabricated with the safety-shoe (PSS), and off-the-shelf (OTS). Foot-to-insole pressure distribution was measured in seven motor tasks replicating typical working activities: single and double-leg standing; weight lifting; stair ascending and descending; normal and fast walking.Wearing CUS within safety shoes resulted in a greater uniform pressure distribution across plantar regions for most of the working activities. Peak pressure at the forefoot during normal walking was the lowest in the custom insole (CUS 275.9 +/- 55.3 kPa; OTS 332.7 +/- 75.5 kPa; PSS 304.5 +/- 54.2 kPa). Normal and fast walking were found to be the most demanding activities in terms of peak pressure.Wearing safety shoes results in high pedobarographic parameters in several foot regions. The use of custom insoles designed on the foot morphology helps decrease peak pressure and pressure-time integral compared to prefabricated featureless insoles. (C) 2016 Elsevier B.V.
