Finite element human body models such as the Total Human Model for Safety (THUMS) have been widely used in automotive safety research, and their applications are now expanding into the medical and clinical fields. Spinal deformities, including scoliosis, are among the most important targets for simulation, since their severity is clinically evaluated using the Cobb angle. In this study, we attempted to reproduce scoliosis alignment in the THUMS spinal model by introducing a spinal alignment control method. Two approaches were compared: one based on applying external moments and the other directly prescribing the Cobb angle.
