Fox (“Back to the Future”), who has Parkinson’s disease, this foundation is the main private donor in the field of research into Parkinson’s disease.The implant is yet to be tested in a full clinical trial. These trials aim not only to validate the technology developed in collaboration with ONWARD, but also to identify the profiles of patients most likely to benefit from this innovative treatment. NeuroRestore centre is going to carry out clinical tests on six new patients next year. Fox Foundation for Parkinson’s research, the. “Our ambition is to provide general access to this innovative technology to improve the quality of life of Parkinson’s patients significantly, all over the world,” they explain.įurthermore, thanks to a generous donation of one million US dollars from the Michael J. In partnership with ONWARD Medical, Grégoire Courtine and Jocelyne Bloch are working on deve- loping a commercial version of the neuroprosthetic, including all the necessary functionalities for optimal everyday use. This neuroprosthetic opens up new possibilities to deal with walking disorders that many people suffering from Parkinson’s diseases are affected by, but at this stage the treatment concept has demonstrated its effectiveness in one person only, with an implant that still needs to be optimised for large-scale use. Every Sunday I go to the lake, and I walk around 6 kilometres. Right now, I’m not even afraid of the stairs anymore. This allows me to walk better and to stabilise. He currently uses his neuroprosthetic for around 8 hours a day, only turning it off when he is sitting down for a long period of time or when he is sleeping: “I turn on the stimulation in the morning and I turn off in the evening. After several weeks of rehabilitation with the neuroprosthetic, he is now able to walk almost normally. Using a targeted programming of spinal-cord stimulations which adapts in real time to his movements, Marc has quickly seen his walking disorder subside.

After a precision neurosurgical procedure, Marc, from Bordeaux, was fitted with this new neuro- prosthetic made up of an electrode field placed against the spinal cord, which controls walking, and an electrical impulse generator implanted under the skin of his abdomen. Two years ago, the team of scientists and doctors were ready, and a first patient was operated on, in Lausanne University Hospital (CHUV). “I’m not even afraid of the stairs anymore” His expertise in preclinical models of Parkinson’s disease was essential to correctly produce the technological and conceptual developments required for clinical application in human beings.

The implantation of this neuroprosthetic in a patient would not have been possible without the collaboration of Dr Erwan Bezard, neuroscientist at Inserm, affiliate at the CNRS and the University of Bordeaux, who has dedicated his career to understanding neurodegenerative diseases. NeuroRestore centre with Grégoire Courtine. “It is impressive to see how by electrically stimulating the spinal cord in a targe- ted manner, in the same way as we have done with paraplegic patients, we can correct walking disorders caused by Parkinson’s disease”, says Jocelyne Bloch, neurosurgeon and professor at the CHUV, UNIL and EPFL, and co-director of the. Unlike conventional treatments for Parkinson’s which target the regions of the brain directly affected by the loss of dopamine-producing neurons, this neuro- prosthetic targets the spinal area responsible for activating leg muscles while walking, which is not seemingly directly affected by Parkinson’s disease. “The idea of developing a neuroprosthetic that stimulates the spinal cord elec- trically to harmonise the procedure and correct locomotor disorders in patients with Parkinson’s is the result of several years of research on the treatment of paralysis due to spinal-cord injuries,” explains Grégoire Courtine, professor of neuroscience at EPFL, the Lausanne University Hospital (CHUV) and UNIL. In some situations, such as entering a lift, I’d trample on the spot, as though I was frozen there, you might say.” “I practically could not walk anymore without falling frequently, several times a day.

More recently, he developed serious walking disorders which did not respond to dopamine or brain stimulation. Dopamine and then the deep brain stimu- lation he received in 2004 dealt with his tremors and stiffness. Marc, 62, has lived with Parkinson’s for almost three decades. These walking disorders are often resis- tant to the treatments that are currently available. Disabling walking disorders occur in around 90% of persons who are at an advanced stage of Parkinson’s disease.
