Muscle activities changing model by difference in sensory inputs on human posture control

Abstract

For understanding of human posture control, changes in muscular activity caused by changes in sensory inputs are very important because the control mechanism is complicated with integrating multi-inputs and outputting various and simultaneous muscular activity. In this research, we aim to obtain quantitative changes in muscular activity caused by changes in sensory inputs. For this purpose, we propose a method to be founded on the idea that muscle activity is divided into external force elements and internal elements. With this method, we can show the existence of internal muscular activity as well as external muscular activity. And it is considered that new model of human posture control with the difference of sensory inputs might be obtained. © 2013 Springer-Verlag.
