A new model for frontal-plane stepping movements is developed in order to evaluate medio-lateral gait movements. Using this model it is possible to study individual stepping parameters, stability of movements and various stepping patterns. Gait research to date has mainly focused on forward locomotion, but as maintaining lateral balance is critical for stable gait, the proposed model concentrates on stepping in the frontal plane. The modeling is carried out on basis of biological principles. The model is accordingly split into chiefly automated tasks performed by the low-level component, mechanics, actuation with neuromuscular feedback, and primarily directive tasks performed by the high-level component, statistical estimation and sensor integration with optimal control. The model is validated by experiments with real subjects, for stepping movements and for influencing posture control by vestibular and visual inputs.
