Abstract     The advantages of multichannel functional electrical stimulation (MFES) therapy for gait training and relearning in hemiplegic patients compared to conventional therapeutic methods (CONV) have already been proven. The purpose of this study was to evaluate on what levels and to what extent do the effects of different therapies take place. Three models of gait rehabilitation process were proposed: exponential, logistic and mixed. The non-linear regression of experimental data was used for parameter estimation for each model respectively. A correlation coefficient was used to evaluate which model fits best. Gait speed during CONV and MFES therapy in 20 hemiplegic patients was used as a measure of gait recovery. The mixed exponential-logistic model showed the best fit to experimental data. The model incorporates two parameters which represent: direct effects of therapy to muscles (functional movements, weight bearing, etc.) and afferent effects of therapy to CNS (motor learning, plasticity, etc.). The comparison of group averages of calculated model parameters for CONV therapy and MFGES therapy showed that both, direct and afferent effects during MFES therapy, are approximately 5 times greater compared to CONV therapy.
