最小足部间隙（MFC），因为它涉及到旅行和福尔斯已被广泛研究了许多运动任务，但检查这一机构的研究产生了一些相互矛盾的结果和任务内的MFC范围广泛的研究。虽然有几个因素可能影响研究中的MFC变异性（研究的人群、环境条件等），文献中的差异的一个方面可能是鞋标记的不同放置和/或MFC计算方法的结果。脚趾上的标记经常被使用，但只能量化脚如何实际清除绊倒危险的一个方面。本研究的目的是确定在运动任务期间发生MFC的鞋上的位置，具有最高的绊倒风险。10名年轻人进行了三项运动任务的试验，包括地上行走，跨越障碍，水平变化和楼梯谈判。每只鞋上的72个点计算清除率，包括过去研究中最常用的点。的位置的整体MFC的鞋底不同的四肢和跨运动任务。此外，MFC发生的障碍物、台阶或楼梯的区域在任务内和任务间都不同。这种3D MFC方法的使用提供了对鞋的哪些部分可能最接近绊倒危险的进一步洞察。未来的研究应该检查MFC的位置和值是否在不同人群之间发生变化，或者随着环境的改变。
Minimum foot clearance (MFC) as it relates to trips and falls has been extensively studied across many locomotor tasks, but examination of this body of research yields several studies with conflicting results and a wide range of MFCs within tasks. While there are several factors that may affect the MFC variability across studies (populations studied, environmental conditions, etc.), one aspect of the discrepancies in the literature may be the result of different placements of shoe markers and/or MFC calculation methods. A marker on the toe is often used, but may only quantify one aspect of how the foot actually clears the trip hazard. The purpose of this study was to determine the location on the shoe where MFC occurs during locomotor tasks with the highest risk of tripping. Ten young adults performed three trials of locomotor tasks which included overground walking, obstacle crossing, level change and stair negotiation. Clearance was calculated for 72 points on each shoe, including those most commonly used in past research. The location of the overall MFC on the shoe sole differed both between limbs and across locomotor tasks. Additionally, the region of the obstacle, step or stair over which the MFC occurred varied both within and across task. Use of this 3D MFC methodology provided further insight into which portions of the shoe may come closest to the tripping hazard. Future research should examine whether the location and value of the MFC changes between different populations, or with environmental modifications.
