Augmenting rehabilitation robotics with spinal cord neuromodulation: A proof of concept

Auke Ijspeert, Grégoire Courtine, Jocelyne Bloch, Léonie Asboth, Robin Jonathan Demesmaeker, Miroslav Caban, Nicolas Hankov, Henri Charles Alexandre Lorach, Fabien Bertrand Paul Wagner, Salif Axel Komi

Rehabilitation robotics aims to promote activity-dependent reorganization of the nervous system. However, people with paralysis cannot generate sufficient activity during robot-assisted rehabilitation and, consequently, do not benefit from these therapies. ...

The spinal cord facilitates cerebellar upper limb motor learning and control; inputs from neuromusculoskeletal simulation

Auke Ijspeert, Henri Charles Alexandre Lorach, Thibault Jean Etienne Collin, Icare Sakr

Complex interactions between brain regions and the spinal cord (SC) govern body motion, which is ultimately driven by muscle activation. Motor planning or learning are mainly conducted at higher brain regions, whilst the SC acts as a brain-muscle gateway a ...

Neuromodulation/neurostimulation system for restoring a motor function and facilitating neurological recovery

Grégoire Courtine, Jocelyne Bloch, Henri Charles Alexandre Lorach

The present invention relates to a neuromodulation/neurostimulation system (100) for restoring a motor function of the upper and/or lower limbs and facilitating neurological recovery in a patient (P) with spinal cord injury (SCI) and/or other neurological ...

Walking naturally after spinal cord injury using a brain-spine interface

Grégoire Courtine, Léonie Asboth, Jocelyne Bloch, Robin Jonathan Demesmaeker, Henri Charles Alexandre Lorach, Thibault Jean Etienne Collin, Anne Marie Lucienne Watrin, Icare Sakr, Sergio Daniel Hernandez, Salif Axel Komi

A spinal cord injury interrupts the communication between the brain and the region of the spinal cord that produces walking, leading to paralysis(1,2). Here, we restored this communication with a digital bridge between the brain and spinal cord that enable ...

Activity-dependent spinal cord neuromodulation rapidly restores trunk and leg motor functions after complete paralysis

Dimitri Nestor Alice Van De Ville, Silvestro Micera, Grégoire Courtine, Jocelyne Bloch, Quentin Barraud, Léonie Asboth, Robin Jonathan Demesmaeker, Nawal Noëlle Kinany, Miroslav Caban, Sergio Daniel Hernandez

Epidural electrical stimulation (EES) targeting the dorsal roots of lumbosacral segments restores walking in people with spinal cord injury (SCI). However, EES is delivered with multielectrode paddle leads that were originally designed to target the dorsal ...

Recruitment of upper-limb motoneurons with epidural electrical stimulation of the cervical spinal cord

Stéphanie Lacour, Grégoire Courtine, Giuseppe Schiavone, Nicholas David James, Simon Borgognon, Henri Charles Alexandre Lorach, Florian Dylan Fallegger, Nathan Antoine Greiner

Epidural electrical stimulation (EES) of lumbosacral sensorimotor circuits improves leg motor control in animals and humans with spinal cord injury (SCI). Upper-limb motor control involves similar circuits, located in the cervical spinal cord, suggesting t ...
