| Abstract | Motor unit recruitment is an essential factor in understanding muscle behavior. Skeleton muscle is associated with force generation and transmission to perform daily activity. The present study aims to compare the number of motor units recruited in human skeleton muscle by finite element analysis. The finite element model is constructed based on the mechanism of the sarcomere. The geometry of the model is focused on the fascicle level which consists of many fibers and is enveloped with an endomysium sheet. Each subunit of fiber is compressible and elongated similar to the sliding filament theory. The fully instrumented model provides information on self-contraction and force distribution along the skeletal muscle. The result of contraction behavior from the finite element model can be applied to designing functional ankle-foot orthosis for various physiology of humans. Results show that the equal distribution of muscle fiber type in a single fascicle achieves the greatest outcome in isotonic contraction toward other activation patterns. The culmination of contraction behavior from the finite element model can be applied to designing functional ankle-foot orthosis for various physiology of humans. |
