职业应用我们研究了鞋子磨损率与描述个人时空步态特征（节奏、步长和首选步行速度）的几个指标之间的关联。没有发现任何关联，这表明应该研究替代指标来预测工人鞋面磨损的个体化速度。技术摘要 背景 穿鞋与工作场所滑倒和跌倒的增加有关。人们以不同的速度磨损鞋面；因此，个性化的换鞋时间表可以改善以时间作为换鞋基础的组织的资源定位。先前的研究发现，鞋与地板的动力学（例如行走时的摩擦力要求）与鞋的磨损率相关。尽管步频、步长或首选步行速度等易于测量的指标与摩擦力要求之间存在关系，但尚未对其使用来预测磨损进行研究。目的本研究旨在确定鞋子磨损率与步态时空特征之间的关联。方法 13 名参与者完成了一项纵向鞋子穿着研究，其中包括步态评估以及两双防滑鞋的长时间穿着。步态评估包括干燥水平地面步行试验；通过光学运动捕捉和测力台收集运动学和动力学数据。计算参与者的平均步频、步长和首选步行速度。然后参与者在工作时穿着鞋子；鞋子的磨损率是通过测量该研究的工作磨损部分期间的周期性体积胎面损失来确定的。结果三个线性回归模型发现所选步态指标与鞋子磨损率之间没有显着关联。结论 时空步态特征与鞋子磨损率之间缺乏关联，表明这些因素可能无法解释参与者之间磨损率的差异。这一负面发现表明，其他措施（例如所需的摩擦系数）更适合个性化鞋类更换指南。
OCCUPATIONAL APPLICATIONS We investigated the association between shoe wear rate and several metrics describing an individual’s spatiotemporal gait characteristics (cadence, step length, and preferred walking speed). No associations were found, indicating that alternative metrics should be investigated to predict the individualized rate at which workers wear down shoe tread. TECHNICAL ABSTRACT Background Shoe wear has been associated with increased slips and falls in the workplace. People wear down shoe tread at different rates; therefore, individualized shoe replacement timelines could improve resource targeting for organizations that use time as a basis for shoe replacement. Previous work has found that the shoe-floor kinetics, such as the friction requirements of walking, correlate with shoe wear rate. The use of easily measured metrics such as cadence, step length, or preferred walking speed to predict wear has not yet been investigated despite their relationship with friction requirements. Purpose This study seeks to determine the association between shoe wear rate and gait spatiotemporal characteristics. Methods Thirteen participants completed a longitudinal shoe wear study that consisted of a gait assessment followed by prolonged shoe wear in two pairs of slip-resistant shoes. The gait assessment was comprised of dry level-ground walking trials; kinematic and kinetic data were collected through optical motion capture and force plates. The participants’ mean cadence, step length, and preferred walking speed were calculated. The participants then wore their shoes at work; the shoe wear rate was determined by measuring the periodic volumetric tread loss during this wear-at-work portion of the study. Results Three linear regression models found no significant association between the chosen gait metrics and the shoe wear rate. Conclusions The lack of an association between the spatiotemporal gait characteristics and shoe wear rate indicates that these factors may not explain the differences in wear rate between participants. This negative finding suggests that other measures such as the required coefficient of friction are better for individualizing footwear replacement guidelines.
