Abstract
The aim of this research is to develop a human gait measurement and evaluation system which gives a quantitative and effective evaluation index of a human lower limb movement. It will be utilized to support a medical examination and a rehabilitation of patients with limb movement disorder. In this paper, we will develop a prototype of a human gait measurement system based on gyro sensors and acceleration sensors attached to a human body, and try to extract walking features from measured data of quasi hemiplegic gait in comparison with normal gait.
