Static and dynamic methods can be used to assess the way a foot is loaded. The research question is how the pressure on the feet would vary depending on walking/running speed. This study involved 20 healthy volunteers. Dynamic measurement of foot pressure was performed using the Ortopiezometr at normal, slow, and fast paces of walking. Obtained data underwent analysis in a "Steps" program. Based on the median, the power generated by the sensors during the entire stride period is the highest during a fast walk, whereas based on the average; a walk or slow walk prevails. During a fast walk, the difference between the mean and the median of the stride period is the smallest. Regardless of the pace of gait, the energy released per unit time does not depend on the paces of the volunteers' gaits. Conclusions: Ortopiezometr is a feasible tool for the dynamic measurement of foot pressure. For investigations on walking motions, the plantar pressure analysis system, which uses the power generated on sensors installed in the insoles of shoes, is an alternative to force or energy measurements. Regardless of the pace of the walk, the amounts of pressure applied to the foot during step are similar among healthy volunteers.
静态和动态方法可用于评估足部的受力方式。研究问题是，足部的压力会如何因步行/跑步速度而变化。本研究涉及 20 名健康志愿者。使用 Ortopiezometr 在正常、缓慢和快速步行速度下对足部压力进行动态测量。在“Steps”程序中分析获得的数据。基于中位数，在整个步幅周期内，传感器产生的功率在快走时最高，而基于平均值；则是步行或慢走占主导。在快走时，步幅周期的平均值和中位数之间的差异最小。无论步态速度如何，单位时间释放的能量都不依赖于志愿者步态的速度。结论：Ortopiezometr 是一种可行的动态测量足部压力的工具。对于步行运动的研究，使用安装在鞋鞋垫上的传感器产生的功率的足底压力分析系统是力或能量测量的替代方法。无论步行速度如何，健康志愿者在步幅期间施加到脚部的压力量相似。
