Abstract:
For effective healthcare, this study develops a wearable estimation method of ground reaction forces during running. So far, we have established a method during walking using fifteen inertial measurement units. Therefore, this report applies it and estimates ground reaction forces in two directions while running. Furthermore, we propose to reduce the number of sensors to 5 using correlation between accelerations so that runners can more easily measure them. The accuracy of each proposed method is compared to the accuracy of the conventional method. As results, the accuracy of the vertical ground reaction force was high even when the number of sensors was reduced, but in the anterior-posterior direction, the accuracy was lower.
