Outline of Final Research Achievements	Currently available musculoskeletal models ignore volume and deformation of the muscles; therefore they cannot accurately reproduce muscles’ line of action around the complex joints such as the shoulder. The present study developed a prototype of the next-generation musculoskeletal model considering muscle volume by reducing the computational burden for computing the muscle shape using GPU (Graphic processing Unit) parallel computing method.
