The purpose of this study is dynamic motion analysis of load control treadmill using inertial sensor and ground reaction force. The wearable sensor system based on inertial sensor outputs angular velocity and acceleration. The posture information is estimated by the sensor fusion using the Extended Kalman filter. The treadmill installs the force plates, and the load control system using propulsion force is installed. The hip, knee and ankle joint torque are calculated by the inertial sensor outputs, the posture information and the force plate output using the Newton-Euler method. The gait measurement experiment was conducted by using the treadmill and the wearable sensor system. The analysis results indicated the difference of joint torque by change of target load in the treadmill. Furthermore, the joint torque including the effect of inclination is calculated, the characteristics gait motion in the load control type treadmill was considered approaching the inclination and the actual road condition.
