本研究的目的是调查一种市售的矫形装置在穿着战斗突击靴跑步时对后足运动和峰值冲击力变量的影响。八名军事受训人员在两种跑步条件下进行跑步试验：靴子和标准鞋垫，靴子和测试矫形器。对于每一个试验，垂直地面反作用力和额状面后足角度的数据进行了收集。结果发现，峰值外翻角不受矫形装置的显著影响（p > 0.05），但该峰值出现在站立位之后（p < 0.05）。使用矫形器时，冲击力峰值、平均加载速率和冲击力峰值加载速率均较低（p < 0.05）。这项研究的结果突出了市售矫正器的潜力，以提供更典型的与模制处方矫正器相关的益处，为处方矫正器的常规使用提供了一种具有成本效益的选择。
The objective of this study was to investigate the influence of a commercially available orthotic device on rearfoot movement and peak impact force variables during running in combat assault boots. Eight military trainees performed running trials under two running conditions: boot with standard-issue insole and boot with the test orthotic. For each trial, vertical ground reaction force and frontal plane rearfoot angle data were collected. It was found that peak eversion angle was not significantly influenced by the orthotic device (p > 0.05), but that this peak occurred later in stance (p < 0.05). Peak impact force, average rate of loading, and peak rate of loading of impact force were all lower when the orthotic device was used (p < 0.05). The findings of this study highlight the potential of a commercially available orthotic to provide benefits more typically associated with molded prescription orthoses, providing a cost-effective option to the routine use of prescription orthotic devices.
