The biomechanics of the foot and ankle are initially discussed, as a series of isolated joints and segments, and subsequently as an integrated unit during the functional activities of walking and running. The kinematics and kinetics of the foot and ankle during the three major components of stance phase are reviewed. The first component, between foot contact and foot flat, is characterized primarily by force absorption. The portion of the gait cycle between foot flat and heel off is associated with controlled forward progression of the center of mass and maximum mobility of the transverse tarsal joint. In the third phase, supination of the foot results in increased rigidity of the transverse tarsal joint, and therefore improved force transmission. The controversy regarding the function of the triceps surae during this phase of the gait cycle is discussed.
首先讨论足踝的生物力学，将其视为一系列孤立的关节和节段，随后在行走和跑步等功能活动中作为一个整体单元进行讨论。回顾了站立期三个主要阶段中足踝的运动学和动力学。第一个阶段，从足接触到足放平，主要特征是吸收力量。步态周期中从足放平到足跟离地的部分与重心的受控向前推进以及横跗关节的最大活动度相关。在第三阶段，足的旋后导致横跗关节硬度增加，从而改善了力的传递。讨论了关于腓肠肌在步态周期该阶段功能的争议。
