Six bipolar electrodes were placed at three levels (UEV, AV, and LEV) of the bilateral MF. After confirmation by X-ray, the sEMG sensors and the inertial measurement unit (IMU) were placed in the appropriate areas. a The three sEMG sensors on the right side. b Left sEMG sensors, each integrated with an IMU, were placed at the corresponding positions of the spinous processes (L1, L3, and L5). c Three axes of the IMU
