| Research Abstract |
The purpose of this study is to develop wearable sensor system for gait evaluation using gyroscopes and accelerometers for application to rehabilitation, healthcare and so on. In this study, simultaneous measurement of joint angles of lower limbs and stride length was tested with a prototype of wearable sensor system. Signals from the sensor attached on the foot were used in the stride length estimation detecting foot movement automatically. High correlation between joint angles at some characteristic points and stride velocity were also found adequately. These results suggested that the wireless wearable sensor system could detect characteristics of gait.
