From brain to motion: harnessing higher-derivative mechanics for neural control
25 novembre 2025, HE Louvain en HainautCeREF SantéCeREF TechniqueArticle scientifiqueOptimal Feedback Control provides a theoretical framework for goal-directed movements, where the nervous system adjusts actions based on sensory feedback. This theory assumes that there exists a cost function that is optimized throughout one's movement. It is natural to assume that mechanical quantities should be involved in cost functions, but this does not imply that the mechanical principles that ... -
Stress on the stride: How treadmill walking reveals gait variability differences in children, young adults, and seniors?
25 septembre 2025, CeREF SantéArticle scientifiqueThe assessment of gait variability is a valuable approach for characterizing an individual’s walking pattern over extended time scales. Variability parameters, such as the coefficient of variation, the Hurst exponent, and the Minkowski fractal dimension of the attractor, are influenced by factors like age, dual-task performance, and neurodegenerative conditions. Treadmill walking, a compact and ... -
t si le cerveau utilisait la physique fondamentale pour piloter nos gestes ?
08 mai 2026, CeREF SantéPublication d'intérêt général/presseSaisir une tasse, écrire son prénom, tendre la main. Des gestes simples, presque automatiques. Derrière cette apparente évidence se cache une question : comment le cerveau choisit-il un mouvement précis parmi une infinité de possibilités pour réaliser ces tâches ?
