Although athletics sprinters with transradial amputation/deficiency can wear arm prosthesis in competition, there have been few researches focusing on arm prosthesis for running and little is known about the effect of arm prosthesis on running motion. In order to investigate the muscle loads when running with forearm prosthesis, the basic musculoskeletal model of a runner which consists of whole skeleton and muscles of trunk and upper extremity was constructed in this study. A trial musculoskeletal analysis with the arm swing motion created manually was conducted. As a result, it was found that the muscle activities of biceps brachii became large when the upper arms pointed downward. In addition, the arm swing motions of the athletes with unilateral transradial amputation wearing forearm prosthesis were measured by the optical motion capture. In the near future, the parameters of the musculoskeletal model will be changed in order to represent the runner wearing forearm prosthesis, and muscle activities of the upper extremity will be calculated by a musculoskeletal analysis with the actual athletes’ motions.
