Abstract

This research is to estimate the hip joint moment without using a force plate that disturbs the gate. The purpose of this research is to show that with a single leg supporting period, the system is statically fixed, making it possible to derive the hip joint moment from the balance of inertial force and gravity without a force plate. Therefore, in this research, a wearable inertial measurement unit was used to measure the acceleration and angle of five body parts, and the hip joint moment was estimated. The proposed method, which estimated the hip joint moment using the inertial measurement unit, and the conventional method which estimated the hip joint moment using the information of the force plate showed similar results. Thus, the validity of the proposed method was obtained.
