This paper describes a system for measuring the temporal and spatial parameters of gait. The basis of the system is a resistive grid walkway which is controlled by a microcomputer which also collects, processes and stores the data from the walkway. The data obtained from the system, including the temporal and spatial parameters of gait such as step and stride lengths, the durations of swing and support phases of the gait cycle and walking speed, are presented in both numerical and graphical forms. Accuracy to within 1 cm has been verified by analysing videotapes of foot placement during a walk. Special emphasis has been placed on making the system software user-friendly. The presentation of date uses several types of display, from a simple graphical summary of the walk statistics to a more complete report showing all the data from each stride. In the year during which the walkway system has been operational, it has been found easy to use by both subjects and operators, and it produces very useful data.
本文介绍了一种用于测量步态时空参数的系统。该系统的基础是一个电阻式网格步道，由一台微型计算机控制，该微型计算机还收集、处理和存储来自步道的数据。从该系统获得的数据，包括步态的时空参数，如步长和步幅、步态周期的摆动和支撑阶段的持续时间以及步行速度，以数字和图形形式呈现。通过分析行走过程中足部位置的录像带，已验证精度在1厘米以内。特别强调使系统软件对用户友好。数据呈现使用多种显示类型，从步行统计的简单图形摘要到显示每个步幅所有数据的更完整报告。在步道系统投入使用的这一年里，发现受试者和操作人员都很容易使用，并且它能产生非常有用的数据。
