Spinal Cord Implant Enhances Mobility In 63-Year Old Parkinson’s Patient

Thanks to an experimental spinal cord implant, a 63-year-old Parkinson’s disease patient named Marc Gauthier from, France, has experienced a remarkable improvement in his ability to walk. Let’s learn more!

Spinal Cord Implant Eases Walking Difficulties in Parkinson’s Patient

This implant, detailed in a recent publication in the journal Nature Medicine, offers hope to individuals suffering from walking disorders associated with Parkinson’s disease.

For nearly three decades, Gauthier grappled with the debilitating effects of Parkinson’s disease, which had gradually eroded his ability to move freely. Everyday tasks such as walking or standing up from a chair became insurmountable challenges due to the freezing of gait—a common symptom of the disease.

In this pioneering study, Gauthier underwent surgery to be implanted with an experimental spinal cord neuroprosthesis. The implant employs targeted electrical stimulation in specific regions of the spinal cord associated with walking, a novel approach that addresses the heterogeneous nature of gait and balance deficits in Parkinson’s patients.

The spinal cord implant focuses on six critical hotspots in the lower spinal cord, responsible for controlling leg movements. A network of electrodes was surgically placed against Gauthier’s spinal cord, connected to a neural stimulator located beneath the skin near the abdomen.

This stimulator was programmed to deliver electrical impulses to the spinal cord, effectively stimulating and enhancing his walking abilities.

Following the procedure, Gauthier underwent rehabilitation with the neuroprosthetic stimulation. Remarkably, he began to regain his independence and mobility. The neuroprosthesis encouraged longer strides, improved balance, and reduced instances of gait freezing.

Gauthier now uses the neuroprosthesis for about eight hours daily, activating it in the morning and deactivating it when he’s stationary or sleeping. He described feeling a slight tingling in his legs during stimulation, which he found tolerable. This newfound mobility has significantly improved his quality of life and allows him to enjoy activities he once struggled with.

While this spinal cord stimulation doesn’t offer a cure, it represents a promising advancement in managing the symptoms of Parkinson’s disease. Gauthier’s condition is expected to continue progressing, but the therapy provides a crucial reprieve from the severe symptoms he once faced.

Dr. Svjetlana Miocinovic, a neurologist specializing in Parkinson’s disease, called this study “exciting” and emphasized the need for further research and clinical testing.

David Dexter, director of research at Parkinson’s UK, underscored the importance of testing the technology in a more extensive patient population, including those who haven’t undergone deep brain stimulation.

A second patient has already initiated the process of this therapy, with plans for clinical trials involving six more Parkinson’s patients in the upcoming year.

The research is supported by a $1 million donation from the Michael J. Fox Foundation, and researchers are collaborating with ONWARD Medical, a Dutch medical technology company, to develop a commercial version of the neuroprosthesis.

While the research is in its early stages, it represents a significant step forward in the quest to restore movement and improve the quality of life for individuals battling advanced Parkinson’s disease. However, it will likely be at least five years before this technology becomes widely available.
