The purpose of this study was to suggest the quantitative evaluation technique of hemiplegic gait and to make a study of its effectiveness. We measured spatial displacement of the back lumbar area (L3) on walking using a triaxial accelerometer. Further, we defined 5 characteristics based on relativeness between idiosyncraticness of hemiplegic gait and feature of kinematics information. In the experiment, the appropriateness of characteristics was estimated from the aspect of the correlation between characteristics and Brunnstrom Stage (BS), and the classification accuracy of BS classification system. The experiment result showed that the characteristics point to intercorrelate with BS. Additionaly, BS classification system could classify with a high degree of accuracy. These results indicated that 5 characteristics were effective in quantitative evaluation of the seriousness of hemiplegic gait and measuring trunk displacement and proposal technique were effective in quantitative evaluation of hemiplegic gait.
