Indirect Manipulation of a Sphere on a Flat Disk Using Force Information

The objective of this study is to verify if only the use of robotic force feedback enables indirect and dynamic manipulations which are difficult for human beings to perform. Human beings usually control the trajectory of an object using visual feedback; f ...

The WalkTrainer, a New Generation of Walking Reeducation Device Combining Orthoses and Muscle Stimulation

Reymond Clavel, Mohamed Bouri, Yves Stauffer, Patrick Métrailler, Jacques Fournier, Yves Allemand

This paper presents a novel reeducation device for paraplegics that combines hybrid orthoses and closed-loop electrical muscle stimulation. Based on the so called Cyberthosis concept, the WalkTrainer enables an active muscular participation of the subject ...

Training locomotor networks

Grégoire Courtine

For a complete adult spinal rat to regain some weight-bearing stepping capability, it appears that a sequence of specific proprioceptive inputs that are similar, but not identical, from step to step must be generated over repetitive step cycles. Furthermor ...

Virtual lesion of ventral premotor cortex impairs visual perception of biomechanically possible but not impossible actions

Silvio Ionta

Single-pulse transcranial magnetic stimulation (TMS) studies show that action observation facilitates the onlooker's cortico-spinal system supporting the notion of motor mirroring. Repetitive transcranial magnetic stimulation (rTMS) over ventral premotor c ...

Predicting locomotor activity via neural ensemble recordings in the primary motor cortex in rats.

The possibility to use information from cortical neurons to drive neuroprosthetic devices is an area that has recently garnered a lot of attention within neuroscience. Most of this research has been directed towards restoring upper limb motility. In this s ...

Effects of attentional focus on postural sway in children and adults

Estelle Palluel

The present study examined, in children aged 4-11 and in adults, the postural control modifications when attention was oriented voluntary on postural sway. Since (1) there are less attentional resources in children than in adults, (2) the selective attenti ...

Pelvic motion measurement during over ground walking, analysis and implementation on the WalkTrainer reeducation device

Reymond Clavel, Mohamed Bouri, Yves Stauffer, Patrick Métrailler, Jacques Fournier, Yves Allemand

Pelvic motions are of great importance while walking, and have thus to be taken into account when developing and controlling rehabilitation devices. This paper will first introduce a new reeducation devices for paraplegic people: the WalkTrainer. This devi ...

Stance- and locomotion-dependent processing of vibration-induced proprioceptive inflow from multiple muscles in humans

Grégoire Courtine

We performed a whole-body mapping study of the effect of unilateral muscle vibration, eliciting spindle Ia firing, on the control of standing and walking in humans. During quiet stance, vibration applied to various muscles of the trunk-neck system and of t ...

Brain-Machine Interfaces through Control of Electroencephalographic Signals and Vibrotactile Feedback

José del Rocio Millán Ruiz

A Brain-Computer Interface (BCI) allow direct expression of its userï¿½s will by interpreting signals which directly reflect the brainï¿½s activity, thus bypassing the natural efferent channels (nerves and muscles). To be correctly mastered, it is needed t ...

A Neurocomputational Model of Impaired Imitation

Aude Billard, Biljana Petreska von Ritter-Zahony

This abstract addresses the question of human imitation through convergent evidence from neuroscience, using tools from machine learning. In particular, we consider a deficit in imitation of meaningless gestures (i.e., hand postures relative to the head) f ...
