Mathematical modelling – tool to diagnosis of human apparatus

There is presented a model of human gait based on power developed by muscle joints in this paper. The mathematical model was presented for healthy subjects, patients with gonarthrosis and patients with Anterior Cruciate Ligaments (ACL). The regression function and the stochastic approximation function were used to the modeling. The differences between the values of model’s coefficients of people with these two pathologies have been compared to the model’s coefficients of healthy subjects. Proposed model is very accurate. The modeling could help to define the level of gait pathology and treatment in a large number of patients
