ABSTRACT ：A new system was described forfoot pressure measurement and gait analysis. The system consisted mainly of a pair ofspecially made shoes, force sensors, data acquisition circuit, an interface and amicrocomputer. The function of software included data acquisition, files management,signal processing and gait parameters abstraction, etc. The unit carried by subjects wasportable and of low-power. The system was easy to use and the measurement result easy tounderstand. Such a system, combined with the 3D kinematics analysis subsystem and forceplates, formed an advanced gait analysis system.
