Abstract:
The architecture and dynamic properties of human muscles are very complex. So, most of the muscles are represented simply by straight-line or curve in musculoskeletal model. The straight-line and curve are called muscle paths. The representation of the muscle path plays a vital role in musculoskeletal model simulation such as the estimation of muscle force. Firstly, we create a black box with the muscle force on the bones as the output signal. Then based on the assumption that there is a muscle path plane (MPP) at any time during joint movement, we construct the space curve function of the muscle path during joint instantaneous movement by mathematical approaches. Finally, we calculate the lengths of the muscle paths and analyze the changes of them during elbow flexion.
