The context of this thesis is the interactive manipulation of complex articulated figures by means of geometric constraints (here called tasks), for the purpose of posture control and design. The goal is to determine a posture satisfying a set of prescribe ...
Nature has developed methods for controlling the movements of organisms with many degrees of freedom which differ strongly from existing approaches for balance control in humanoid robots: Biological organisms employ kinematic synergies that simultaneously ...
Dual-task related gait changes have been previously reported for healthy older adults, suggesting that gait control requires attention. Compared to balance control, the involvement of attention in the control of the rhythmic stepping mechanism, as reflecte ...
Les effets de la vibration musculaire peuvent généralement persister après la fin de la stimulation. L’extinction de ce post-effet fut étudié durant la marche humaine. Six sujets ont réalisé une tâche locomotrice (six pas successifs) en condition témoin, e ...
There is a growing interest in the role played by attention and cognitive processing in the control of posture and gait, investigated by means of dual task methodology. The rationale for dual task testing is to assess whether the simultaneous performance o ...
A new method of physical activity monitoring is presented, which is able to detect body postures (sitting, standing, and lying) and periods of walking in elderly persons using only one kinematic sensor attached to the chest. The wavelet transform, in conju ...
Visual amplification of kinematic errors has successfully been applied to improve performance for upper limb movements. In this study, we investigated whether visual error augmentation can promote faster adaptation during a full-body balance task. Healthy ...
INTRODUCTION: Motor performance in Park-inson’s Disease (PD) patients is generally analyzed in laboratory. However, laboratory techniques do not allow estimating long-term ON/OFF fluctua-tion in PD patients. Here, we propose an ambula-tory system based on ...
Footwear is supposed to have influence on postural control and is a potential aspect to address in the prevention of falls in the elderly. This study aimed to show whether measurements of static balance and gait are different with habitual shoes compared t ...
