Tetraplegic moves towards taking walks
Thanks to a four-limb robotic system controlled by brain signals, a patient with a cervical spinal cord injury could walk and control both arms for the first time in a proof of concept. Developed by CEA (French Alternative Energies and Atomic Energy Commission), the system is driven via the long-term implant of a semi-invasive medical device to record brain activity.
