Walking rehabilitation aims to return daily life through the gait training and to assist the muscle strength weakened hemiplegia and the elderly, such as stroke patients. Gait rehabilitation, it is to work in accordance with the walking pedestrian is important. In this paper, we propose a method that determines the speed of movement of pedestrians through the moving distance estimation and pedestrian stride distance estimation using the IMU sensor as ways to use for everyday life return through walking rehabilitation. Experiments stride estimation compared the results by walking stride constant distance constant. The experimental results, errors in stride estimation was confirmed by 8.67%.
