Walking ability is an indispensable factor for the elderly to be independent in this aging society. Therefore, it is significant to evaluate the state of elderly gait quantitatively. We propose a new method of evaluating elderly gait from acceleration signals during walking. The accelerometer has a great advantage over conventional Gait Analysis System in measurement at routine level, for it does not restrict subjects because it is small and light. In the present study, from the view point of gait dispersion, we attempted to characterize elderly gait from acceleration signals at waist close to the center of gravity of the body. A healthy young subject and an elderly subject performed free level walking. The data were analyzed on gait reproducibility using Correlation Coefficient. The elderly subject exhibited greater dispersion than did the healthy young subject. Then, it is concluded that the method enables easy and simple characterization of elderly gait.
