Abstract :
A surface EMG (SEMG) to force model is presented. An SEMG processor was developed based on a mathematical model of recorded SEMG. The processed SEMG and joint angle are the inputs of the muscle model which is a Hill-type muscle model. An anatomy matrix, which allows the transformation from muscle forces to moments acting about the joint, was determined based on the segment-link model. The method by which to determine the parameter values of the muscle model and the scaling factor of the SEMG is discussed. Human elbow flexion is chosen to describe the method as well as to evaluate the performance of the SEMG/force model
