Abstract
The objective of this study was to clarify the muscle load of pregnant women during walking with musculoskeletal simulation. For this objective, we conducted the experimental walking test using 3D motion analysis system, forceplates and electrodes on erector spinae. A subject put on habiliments for pregnancy mock and we obtained motions of body in non-pregnant and pregnant conditions. The motions of body were input in the musculoskeletal simulation and muscle loads around back were analyzed. From the simulation result, the muscle load in pregnant condition was 193% of the one in non-pregnant condition. On the other hand, the muscle load in pregnant condition was 170% of the one in non-pregnant condition in the experiment We showed the possibility that the muscle load of pregnant women could be analyzed by the musculoskeletal simulation.
