    This study measured the twist angle of the lumbar region and the surface electromyogram (EMG) and examined their correlation to elucidate the influence of “twist” on lower back pain (LBP). Using a goniometer (two-way angle and twist sensors) and an EMG (SX230;DKH Co., Ltd.), we conducted measurement by affixing the goniometer on the lumbar vertebral column and the EMG sensor on the right and left sides of L4 (of the erector muscle of the spine). The results show that EMG has higher correlation with twist angle in a standing posture keeping feet closed and has higher correlation with the twist angular velocity in a standing posture keeping feet open in breadth of shoulders. And twist with anteversion has an influence on the lumbar region more.
