Contrôle et guidage de la locomotion humaine

Abstract : The aim of this experimental work is to provide elements of understanding relatively to some organizing principles of human locomotion. Its originality comes from the analysis of human locomotion through its sensorimotor and cognitive components: here, locomotion is thought and analyzed as a motor activity that
combines a continuous, fine coordination of the limbs and trunk across each step with the planning strategies of goal-directed movements. Thus, two levels of description of locomotion are considered, the analysis of the processes underlying the generation and control of both the locomotor pattern (across each step cycle) and the locomotor trajectory. The own and combined effects of the speed, the mode of locomotion as well as the geometrical properties of the path, on the regulation of locomotor activity are tested. This is realized mainly through kinematic recordings but also using electromyographic and videooculographic measurements. The origins of some kinematic invariants that were reported both for step and path formation are studied and the organization of head, eye and body movements for the steering of
locomotion is characterized. Finally, the interests of some general approaches and principles, like the notions of segmentation and optimality, are discussed within the general framework of locomotor path planning.
