Use of electromyography measurement in human body modeling

Abstract

The aim of this study is to test the use of the human body model for the muscle activity computation. This paper shows the comparison of measured and simulated muscle activities. Muscle active states of biceps brachia muscle are monitored by method called electromyography (EMG) in a given position and for given subsequently increasing loads. The same conditions are used for simulation using a human body model (Hynčík, L., Rigid Body Based Human Model for Crash Test Purposes, EngineeringMechanics, 5 (8) (2001) 1–6). This model consists of rigid body segments connected by kinematic joints and involves all major muscle bunches. Biceps brachia active states are evaluated by a special muscle balance solver. Obtained simulation results show the acceptable correlation with the experimental results. The analysis shows that the validation procedure of muscle activities determination is usable.
