Research Abstract

We developed a musculoskeletal computer model for laboratory mice, whose genetic backgrounds have been established. We employed the motion capture technology to establish a totally new framework for mouse motor function analyses with the musculoskeletal computer model. To develop a reliable musculoskeletal computer model for laboratory mice, we devised a new method to map information on a human musculoskeletal model onto a mouse skeletal model. Furthermore, we performed validation and improvement of the model by using 3-dimensional geometries of tendon tissues reconstructed from sliced data of a transgenic mouse.
