A personal computer-based system for walking analysis is shown. The system, which is both portable and low in cost, is constructed with a personal computer system and two measuring subsystems with a microprocessor for measurement, communication, and control. For data acquisition and processing, a personal computer-based acquisition system has been used. The sampling rate of the system is 60 frames per second. One of the measuring subsystems uses equipment for measuring pressure distribution under the foot. The sensor for measuring pressure distribution under the foot is composed of a 0.3mm thick anisotropically electroconductive silicon rubber sheet (AF sheet) that is sandwiched in between the matrixed upper and lower electrodes. The sensor is inexpensive and easily attachable to the foot. Dependence of the hysteretic characteristics of the sensor cell on applied loading frequency and maximum applied load are measured with a trial device for measuring dynamic characteristics. Then the sensor is represented as a three-parameter model consisting of a Maxwell element in parallel with a spring. The other measuring subsystem uses equipment for the detection of marked point locations for kinematic analysis. Five lamp markers are attached on anatomical landmarks of the subject, who is tracked by Saticon camera. The marked point location digital data are memorized in real time by a personal computer through the marked point detector and ring buffer memory. Results for human walking experiments on both floor and treadmill have been shown.
