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 ...
IOP Publishing Ltd2022Spinal 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 ...
Springer2017A 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 ...
Springer International Publishing Ag2017Spatiotemporal 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 ...
Nature Publishing Group2016Robust 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 ...
2014Role 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 ...
2012Geometry- and load-specific optimization of the collagen network's fibre orientation in the lumbar spine's annulus fibrosus
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 ...
2010Kinematic and EMG Determinants in Quadrupedal Locomotion of a Non-Human Primate (Rhesus)
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 ...
2005A 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 ...
EPFL2002A t(2;8) balanced translocation with breakpoints near the human HOXD complex causes mesomelic dysplasia and vertebral defects
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 ...
