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. ...

System for control of spasticity

Grégoire Courtine, Jocelyne Bloch, Robin Jonathan Demesmaeker, Fabien Bertrand Paul Wagner, Karen Minassian, Salif Axel Komi

The present invention relates to a neuromodulation/neurostimulation system (10) for the treatment of spasticity in a mammal, said system (10) comprising: - at least one control unit (12) configured and arranged to provide stimulation data, and - at least o ...

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 ...

The neurons that restore walking after paralysis

Stéphanie Lacour, Grégoire Courtine, Jocelyne Bloch, Quentin Barraud, Jordan Squair, Léonie Asboth, Katia Galan, Robin Jonathan Demesmaeker, Nicholas David James, Matthieu Pierre Gautier

A spinal cord injury interrupts pathways from the brain and brainstem that project to the lumbar spinal cord, leading to paralysis. Here we show that spatiotemporal epidural electrical stimulation (EES) of the lumbar spinal cord(1-3) applied during neurore ...

Neuroprosthetic baroreflex controls haemodynamics after spinal cord injury

Stéphanie Lacour, Grégoire Courtine, Jocelyne Bloch, Eduardo Martin Moraud, Quentin Barraud, Jordan Squair, Giuseppe Schiavone, Ileana Ozana Jelescu, Mark Andrew Anderson, Robin Jonathan Demesmaeker

Spinal cord injury (SCI) induces haemodynamic instability that threatens survival(1-3), impairs neurological recovery(4,5), increases the risk of cardiovascular disease(6,7), and reduces quality of life(8,9). Haemodynamic instability in this context is due ...

Electrical spinal cord stimulation protocols to regulate neurological functions after spinal cord injury

Salif Axel Komi

Spinal cord injury (SCI) is a life-changing event. People who suffer from it lose their ability to move normally and are subject to life-threatening symptoms. When the insult is not too severe, partial recovery is possible. Otherwise, for severely affected ...
