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

Grégoire Courtine, Jocelyne Bloch, Léonie Asboth, Robin Jonathan Demesmaeker, Nicolas Hankov, Jimmy James Ravier, 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 ...

Spinal joint compliance and actuation in a simulated bounding quadruped robot

Auke Ijspeert, Alexander Spröwitz, Soha Pouya, Mohammad Khodabakhsh

Spine movements play an important role in quadrupedal locomotion, yet their potential benefits in locomotion of quadruped robots have not been systematically explored. In this work, we investigate the role of spinal joint actuation and compliance on the bo ...

A Computational Framework for the Design of Spinal Neuroprostheses

Silvestro Micera, Grégoire Courtine, Jocelyne Bloch, Marco Capogrosso

Severe Spinal Cord Injury (SCI) alters the communication between supra-spinal centers and the sensorimotor networks coordinating limb movements, which are usually located below the injury. Epidural electrical stimulation of lumbar segments has shown the ab ...

Spatiotemporal neuromodulation therapies engaging muscle synergies improve motor control after spinal cord injury

Silvestro Micera, Stéphanie Lacour, Grégoire Courtine, Jocelyne Bloch, Eduardo Martin Moraud, Quentin Barraud, Léonie Asboth, Marco Capogrosso, Pavel Musienko, Rubia van den Brand, Ivan Rusev Minev, Nikolaus Wenger, Jérôme Gandar, Arthur Edouard Hirsch, Laetitia Danielle Philippine Baud, Natalia Pavlova, Simone Ellen Joze Duis, Julie Kreider, Andrea Mortera

Electrical neuromodulation of lumbar segments improves motor control after spinal cord injury in animal models and humans. However, the physiological principles underlying the effect of this intervention remain poorly understood, which has limited the ther ...

Robust Walking Using Peicewise Linear Spring

Auke Ijspeert, Mahdi Khoramshahi

Having a direct impact on the energy efficiency has made the compliance a favorable element in the robotic systems. Moreover, legged system can benefit from compliance for stability, speed, adaptability and robustness. Recently, we have studied the effects ...

Role of Spine Compliance and Actuation in the Bounding Performance of Quadruped Robots

Auke Ijspeert, Soha Pouya, Rico Möckel, Mohammad Khodabakhsh

In this contribution we introduce novel dynamics model based on existing dynamics modeling approaches that allow detailed studies on the role of a compliant spine in quadruped locomotion. We use this model to address our key questions on locomotion control ...

Geometry- and load-specific optimization of the collagen network's fibre orientation in the lumbar spine's annulus fibrosus

Andreas Schmocker

In Europe, low back pain (LBP) affects the quality of life of up to 30% of the active population. Although the origin of LBP is not well identified and is probably not unique, epidemiological studies suggest that the severity of the disease is correlated w ...

Kinematic and EMG Determinants in Quadrupedal Locomotion of a Non-Human Primate (Rhesus)

Grégoire Courtine

We hypothesized that the activation patterns of flexor and extensor muscles and the resulting kinematics of the forelimbs and hindlimbs during locomotion in the Rhesus would have unique characteristics relative to other quadrupedal mammals. Adaptations of ...

A calcium phosphate implant with controlled macroporosity for anterior L5-S1 interbody fusion

In the United States approximately 50 million people suffer from low back pain. In the 20-50 years age group, this is the most important and expensive health care problem. The causes of low back pain are various. A herniated disk or spinal stenosis may tra ...

A t(2;8) balanced translocation with breakpoints near the human HOXD complex causes mesomelic dysplasia and vertebral defects

Denis Duboule

Mesomelic dysplasia is a severe shortening of forearms and forelegs, and is found in several distinct human syndromes. Here, we report the cloning of the breakpoints of a human t(2;8)(q31;p21) balanced translocation associated with mesomelic dysplasia of t ...
