Clinical implementation of accelerated T-2 mapping: Quantitative magnetic resonance imaging as a biomarker for annular tear and lumbar disc herniation

Tobias Kober, Tom Hilbert, Michael Weber

Objectives This study evaluates GRAPPATINI, an accelerated T-2 mapping sequence combining undersampling and model-based reconstruction to facilitate the clinical implementation of T-2 mapping of the lumbar intervertebral disc. Methods Fifty-eight individua ...

Refinements of hybrid neurophysical volume conductor models and application to study epidural electrical stimulation of the cervical spinal cord

Nathan Antoine Greiner

After spinal cord injury (SCI), the communication between the brain and spinal neural circuits below the lesion is disrupted, leading to paralysis. Epidural electrical stimulation (EES) of the lumbosacral spinal cord has been shown to restore locomotion an ...

Neuroprosthetic Technologies to Evaluate and Train Leg Motor Control in Neurologically Impaired Individuals

Camille Georgette Marie Le Goff-Mignardot

Spinal cord injury (SCI) disrupts many essential sensorimotor and autonomic functions. Consequently, individuals with SCI can face decades with permanent disabilities. Advances in clinical management have decreased morbidity, but no clinical trial has yet ...

Automatic clustering of spinal reflexes evoked by epidural electrical stimulation of the cervical spinal cord in non-human primates

Stéphanie Lacour, Grégoire Courtine, Jocelyne Bloch, Marco Capogrosso, Giuseppe Schiavone, Beatrice Barra, Katie Zhi Zhuang, Sara Conti

Epidural electrical stimulation of the spinal cord elicits motor responses by recruiting large sensory afferents in the posterior roots. Divergence of excitatory inputs provided by these fibers generates a variety of shapes, latencies and amplitudes in the ...

Spatiotemporal stimulation strategies in neuroprostheses to improve locomotion after spinal cord injury

Jérôme Gandar

Spinal cord injury (SCI) disrupts communication within central nervous system and lead to range of neurological disorders including paralysis. Current rehabilitation strategies to restore locomotion are poorly effective in people with severe SCI. Epidural ...

A photopolymerized composite hydrogel and surgical implanting tool for a nucleus pulposus replacement

Dominique Pioletti, Pierre-Etienne Bourban, Christophe Moser, Andreas Schmocker, Azadeh Khoushabi

Nucleus pulposus replacements have been subjected to highly controversial discussions over the last 40 years. Their use has not yet resulted in a positive outcome to treat herniated disc or degenerated disc disease. The main reason is that not a single imp ...

Surgical probe and implant development for nucleus pulposus replacements

Andreas Schmocker

Intervertebral disc degeneration is a major reason why we experience low back pain. Intervertebral discs are located in-between the vertebrae of the spine. They act, among other, as shock absorbers by distributing the mechanical load applied to the spine w ...

The Impact of Spinal Cord Nerve Roots and Denticulate Ligaments on Cerebrospinal Fluid Dynamics in the Cervical Spine

Bryn Andrew Martin

Cerebrospinal fluid (CSF) dynamics in the spinal subarachnoid space (SSS) have been thought to play an important pathophysiological role in syringomyelia, Chiari I malformation (CM), and a role in intrathecal drug delivery. Yet, the impact that fine anatom ...

Multi-Scale Modeling Of Photopolymerization For Medical Hydrogel-Implant Design

Dominique Pioletti, Pierre-Etienne Bourban, Andreas Schmocker, Salma Farahi, Azadeh Khoushabi

We report on the modeling of a photopolymerizable hydrogel and its application as a replacement of the interior of the intervertebral disc (so called Nucleus Pulposus). The hydrogel is initially injected in its liquid form and then photopolymerized via a s ...

Objective evaluation of cervical spine mobility after surgery during freeliving activity

Kamiar Aminian, Cyntia Duc

Background: Evaluation of cervical spine mobility after surgery is mainly based on the measurement of the range of motion during imposed movements. It can thus be questionable if this assessment represents the mobility experienced during daily life. The go ...
