La complexité du mouvement humain : aspects théoriques et pratiques de l’évaluation et de l’interaction des complexités au service de la réhabilitation

Abstract : Just look at our top athletes, their ability to adapt in record-breaking times during sudden changes in tactical phases, or the near-perfect coordination of Olympic-level synchronized swimmers to understand that human movement cannot be reduced to any model of excessive simplicity. Here we propose an application of the complexity sciences, and more particularly of fractal analysis methods aimed at giving a global picture of the complexity of human movement. In a first step, from the theoretical aspects, until their practical application, we show that the finest evaluation of the fractal exponents requires the combined use of a very specific fractal analysis and physiological task. Then, in a second step, we are interested in the coordination of two complex systems. Starting from several theoretical frameworks existing in the field of human movement sciences, we propose new methods to analyze this synchronization. Finally, all the works that we present are attached to rehabilitation goals and we show that despite a typical alteration of complexity with aging there are simple and effective ways to restore this complexity.
