The method and results of hip joint muscle characteristics simulation on the basis of Hill type model and experimental data

The subject considered in the paper is a part of work in which the main gole is creation of the tool for evaluation of patient hip joint internal loadings especially before and after arthroplasty. Internal loadings evaluation in human motion structures is still a present task in biomechanics and biomechanical engineering. The forces of muscle actuators were considered before in the aspect of control of the joint motion. At present, commonly with arthroplasty development, more important became the problem of the muscle forces reaction on the bone structures. Evaluation of muscle characteristics during rotation movement of the femur is the step for calculation of real hip joint muscle forces.
