确定步行模式的参数的澄清对于理解步行机制是重要的。婴儿行走的姿势与成人不同，婴儿行走的动力学特征也与成人不同。“行走姿势”可以提供一组确定行走模式的参数。本研究以成年人为对象，探讨步行姿势对外力的影响，并检验步行姿势与外力之间是否存在关系。20名受试者，年龄18 ~ 22岁，以正常姿势、躯干前倾和躯干后倾行走，16名受试者以正常姿势、膝关节屈曲和膝关节僵硬行走，20名受试者以正常姿势、双腿张开和双腿闭合行走。正常姿势与其他姿势的比较结果表明，步行姿势的差异影响外力。我们确信，行走姿势和外力之间存在因果关系。
The clarification of parameters to determine the walking pattern is important for the understanding of the walking mechanism. Infants walk with different postures from adults, and the dynamic characteristics in infants differ from those in adults. It is possible for the “walking posture” to provide a set of the parameters which determine the walking pattern. This study examines the influence of walking postures on the external forces for adult subjects and tests the existence of a relationship between the walking posture and the external forces. 20 subjects, aged 18 to 22, walked with normal posture, forward-inclined trunk and backward-inclined trunk, other 16 subjects walked with normal posture, flexed knees and stiff knees, other 20 subjects walked with normal posture, open legs and closed legs. The results of the comparison between normal posture and the other postures show that the differences in walking posture influence the external forces. We are confident that there are causal relationships between the walking posture and the external forces.
