Abstract
Namba walking style, known as a movement that reduces rotational movement around the pelvic cross-section, was used in
ancient Japan. This study of five participants was conducted to investigate differences between normal walking and Namba walking and to
use a musculoskeletal model to analyze normal walking and Namba walking. Moreover, a three-dimensional motion analysis system and force plates were used to assess normal and Namba walking. Measured data were analyzed using musculoskeletal model analysis software (OpenSim) procedures: scaling, inverse kinematics, inverse dynamics, and static optimization. Results indicated that four muscle forces related to the upper leg were decreased, whereas two muscle forces related to the lower leg were increased.
