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. ...

Hypothalamic deep brain stimulation augments walking after spinal cord injury

Grégoire Courtine, Jocelyne Bloch, Quentin Barraud, Léonie Asboth, Mark Andrew Anderson, Katia Galan, Robin Jonathan Demesmaeker, Nicholas David James, Matthieu Pierre Gautier, Nicolas Hankov

A spinal cord injury (SCI) disrupts the neuronal projections from the brain to the region of the spinal cord that produces walking, leading to various degrees of paralysis. Here, we aimed to identify brain regions that steer the recovery of walking after i ...

Neuromodulation/neurostimulation system for controlling a respiratory function

Grégoire Courtine, Jocelyne Bloch, Léonie Asboth, Vincent Delattre, Robin Jonathan Demesmaeker, Miroslav Caban, Nicolas Hankov

The present invention relates to a neuromodulation/neurostimulation system for supporting and/or controlling a function of t he respiratory system of a patient, said function comprising a plurality of phases each involving one or more muscles. The system c ...

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 ...

Neuromodulation/neurostimulation system for mitigating locomotor deficits of parkinson's disease, spinal cord injury (sci), stroke and/or other neurological disorders

Grégoire Courtine, Jocelyne Bloch, Eduardo Martin Moraud, Jordan Squair, Léonie Asboth, Tomislav Milekovic, Robin Jonathan Demesmaeker, Newton Cho

The present invention relates to a combined neuromodulation and/or neurostimulation system (10) for mitigating locomotor deficits of/or neuronal disorders, especially Parkinson's disease, said system (10) comprising: - at least one Deep Brain Stimulation ( ...

A spinal cord neuroprosthesis for locomotor deficits due to Parkinson's disease

Auke Ijspeert, Silvestro Micera, Stéphanie Lacour, Grégoire Courtine, Jocelyne Bloch, Eduardo Martin Moraud, Jordan Squair, Giuseppe Schiavone, Léonie Asboth, Tomislav Milekovic

People with late-stage Parkinson's disease (PD) often suffer from debilitating locomotor deficits that are resistant to currently available therapies. To alleviate these deficits, we developed a neuroprosthesis operating in closed loop that targets the dor ...

Wireless closed-loop optogenetics across the entire dorsoventral spinal cord in mice

Stéphanie Lacour, Grégoire Courtine, Quentin Barraud, Léonie Asboth, Ileana Ozana Jelescu, Ivan Furfaro, Kyungjin Kim, Jérôme Gandar, Frédéric Pierre Gérald Michoud, Claudia Kathe

Optoelectronic systems can exert precise control over targeted neurons and pathways throughout the brain in untethered animals, but similar technologies for the spinal cord are not well established. In the present study, we describe a system for ultrafast, ...

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 ...

Targeted dorsal root entry zone stimulation alleviates pain due to meralgia paresthetica

Grégoire Courtine, Léonie Asboth, Jocelyne Bloch, Robin Jonathan Demesmaeker, Jimmy James Ravier, Nicolas Hankov, Viviana Aureli, Molywan Vat

Objective. Meralgia paresthetica (MP) is a mononeuropathy of the exclusively sensory lateral femoral cutaneous nerve (LFCN) that is difficult to treat with conservative treatments. Afferents from the LFCN enter the spinal cord through the dorsal root entry ...

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 ...
