Swiss researchers have enabled three paraplegic patients to stand and walk again, using a nerve-stimulating device that’s controlled by a tablet. Device uses electronic implants and artificial intelligence software to help patients gain back their autonomy. Researchers found it works faster than other previous attempts at electrical stimulation of the spinal cord. Improvement seen within just one day of treatment and continued over months.
Scientists have developed a device that sends personalized signals to the spinal nerves that are responsible for controlling leg and trunk movements. Instead of stimulating nerves through the back of the spine, the device has been redesigned so that electrical signals reach the spine through the person’s sides. This allows for very specific targeting and activation of spinal cord regions.
Three trial patients in a Swiss study have regained the ability to walk and participate in more advanced activities like swimming and cycling with the help of a wearable prosthetic leg. The device, developed by researchers at the Swiss Federal Institute of Technology, is being developed by a Dutch-based company.
Physically disabled patients with a prosthetic leg have regained the ability to walk, but need help with weight-bearing and balance, researchers say. Once the device was implanted, patients could “immediately activate their legs and step,” researcher David Bloch says. But they did not regain natural movements, such as controlling their trunk muscles for “extensive periods”.
