A semi-portable system based on a microcomputer has been developed to measure the vertical reaction forces on both feet during walking. Eight capacitive force transducers are attached to each sole of the patients' shoes. This allowed the forces to be measured for several consecutive steps during a walk of 20 sec. This article describes the principles of operation of the force transducers and the associated electronic system. It also shows data processing procedures and gives a review of the available methods of data presentation. Recordings of the walking pattern of three patients with different diagnostics are presented and discussed to demonstrate the usefulness of the new gait analysis system in a rehabilitation center.
已开发出一种基于微型计算机的半便携式系统，用于测量行走过程中双脚的垂直反作用力。八个电容式力传感器分别附着在患者鞋底。这使得在20秒的行走过程中能够连续测量几步的力。本文描述了力传感器及相关电子系统的工作原理。还展示了数据处理程序，并对现有的数据呈现方法进行了综述。给出并讨论了三名患有不同疾病患者的行走模式记录，以证明新步态分析系统在康复中心的实用性。
