| Research Abstract |
In this study, we constructed an anatomically-based musculoskeletal model of the Japanese macaque hand and biomechanically analyzed the precision grip movement based on inverse dynamic calculation. Specifically, we measured hand kinematics and forces applied to fingertips during a precision grip task in a macaque, and the obtained data were then input to the constructed model to estimate muscular forces exerted based on inverse dynamic calculation. The estimated muscular force patterns are generally in accordance with reported electromyographic data, demonstrating the validity and efficacy of the constructed model for comprehensive understanding of precision grip control in primates.
