Spinal cord injury researchSpinal cord injury research seeks new ways to cure or treat spinal cord injury in order to lessen the debilitating effects of the injury in the short or long term. There is no cure for SCI, and current treatments are mostly focused on spinal cord injury rehabilitation and management of the secondary effects of the condition. Two major areas of research include neuroprotection, ways to prevent damage to cells caused by biological processes that take place in the body after the injury, and neuroregeneration, regrowing or replacing damaged neural circuits.
Traumatisme médullaireUn traumatisme médullaire ou traumatisme de la moelle épinière (ou moelle spinale) met en jeu le pronostic vital immédiat ou retardé. Il est à l'origine de troubles moteurs et sensitifs, et de troubles des fonctions neuro-végétatives. La médicalisation systématique et les progrès de la prise en charge pré-hospitalière ont permis d'améliorer considérablement la survie de ces blessés. L'évolution des connaissances, notamment dans la physiopathologie des lésions cellulaires, fait proposer régulièrement de nouvelles attitudes thérapeutiques, parfois controversées.
NeuroprostheticsNeuroprosthetics (also called neural prosthetics) is a discipline related to neuroscience and biomedical engineering concerned with developing neural prostheses. They are sometimes contrasted with a brain–computer interface, which connects the brain to a computer rather than a device meant to replace missing biological functionality. Neural prostheses are a series of devices that can substitute a motor, sensory or cognitive modality that might have been damaged as a result of an injury or a disease.
Neuromodulation (medicine)Neuromodulation is "the alteration of nerve activity through targeted delivery of a stimulus, such as electrical stimulation or chemical agents, to specific neurological sites in the body". It is carried out to normalize – or modulate – nervous tissue function. Neuromodulation is an evolving therapy that can involve a range of electromagnetic stimuli such as a magnetic field (rTMS), an electric current, or a drug instilled directly in the subdural space (intrathecal drug delivery).
Trouble neurologiqueA neurological disorder is any disorder of the nervous system. Structural, biochemical or electrical abnormalities in the brain, spinal cord or other nerves can result in a range of symptoms. Examples of symptoms include paralysis, muscle weakness, poor coordination, loss of sensation, seizures, confusion, pain and altered levels of consciousness. There are many recognized neurological disorders, some relatively common, but many rare. They may be assessed by neurological examination, and studied and treated within the specialities of neurology and clinical neuropsychology.
Spinal cord stimulatorA spinal cord stimulator (SCS) or dorsal column stimulator (DCS) is a type of implantable neuromodulation device (sometimes called a "pain pacemaker") that is used to send electrical signals to select areas of the spinal cord (dorsal columns) for the treatment of certain pain conditions. SCS is a consideration for people who have a pain condition that has not responded to more conservative therapy. There are also spinal cord stimulators under research and development that could enable patients with spinal cord injury to walk again via epidural electrical stimulation (EES).
Neurostimulationvignette|Implant cochléaire un appareil électronique qui stimule le nerf auditif grâce à des électrodes placées dans la cochlée de l'oreille interne, permettant à certaines personnes gravement sourdes de percevoir les sons. Pour les personnes souffrant de perte auditive sévère à profonde, les appareils auditifs implantables comme les implants cochléaires peuvent être une solution efficace La neurostimulation est la stimulation d'un nerf ou de plusieurs nerfs, de la moelle épinière ou d'une partie du cerveau (système nerveux central) à l'aide de neurostimulateurs.
Moelle spinaleLa moelle spinale (selon la nouvelle nomenclature), ou moelle épinière (dans l’ancienne nomenclature), désigne la partie du système nerveux central qui prolonge la moelle allongée appartenant au tronc cérébral. Elle est contenue dans le canal rachidien (canal formé par la superposition des foramens vertébraux), qui la soutient et la protège. Elle est constituée de neurones et de cellules gliales. Sa fonction principale est la transmission des messages nerveux entre le cerveau et le reste du corps.
NeuromodulationLe mot neuromodulation a un sens différent en neuroscience et en médecine. Dans ce domaine, la neuromodulation est le processus par lequel plusieurs classes de neurotransmetteurs du système nerveux régulent plusieurs populations de neurones. À l'opposé de la transmission synaptique, dans laquelle un neurone présynaptique influence directement un pair postsynaptique, les transmetteurs neuromodulateurs sécrétés par un groupe restreint de neurones se diffusent à travers le système nerveux, ayant un impact sur de multiples neurones.
Functional neurologic disorderFunctional neurologic disorder or functional neurological disorder (FND) is a condition in which patients experience neurological symptoms such as weakness, movement disorders, sensory symptoms and blackouts. As a functional disorder there is by definition no disease process affecting the structure of the body, yet the person experiences symptoms relating to their body function. Symptoms of functional neurological disorders are clinically recognisable, but are not categorically associated with a definable organic disease.
