The temporal relations between the phases of the stride have been investigated in 23 subjects of both sexes and with an age from 20 to 70 years. They were requested to walk freely in five different speeds from very slow to very fast. Equations defining the relations between the different phases of the stride have been set up as well as equations of regression for stride length and cadence versus velocity, for cadence versus stride length and for the phases of the stride versus stride duration. The equations may be used to predict expected values from known velocities and stride durations in pathological cases and help to explain the interaction between different phases of the stride. In pathological cases they may therefore be used for a better understanding of the dynamic relations between the primary disturbance and the compensating postural reactions.
对23名年龄在20至70岁之间的男女受试者的步幅各阶段之间的时间关系进行了研究。要求他们以从非常慢到非常快的五种不同速度自由行走。已经建立了定义步幅不同阶段之间关系的方程，以及步幅长度和步频与速度、步频与步幅长度、步幅阶段与步幅持续时间的回归方程。这些方程可用于根据病理情况下已知的速度和步幅持续时间预测预期值，并有助于解释步幅不同阶段之间的相互作用。因此，在病理情况下，它们可用于更好地理解原发性干扰与代偿性姿势反应之间的动态关系。
