Walking again after spinal cord injury - © EPFL+CHUV

Three patients with chronic paraplegia were able to walk over ground thanks to precise electrical stimulation of their spinal cords via a wireless implant. In a double study published in Nature and Nature Neuroscience, Swiss scientists Grégoire Courtine (EPFL and CHUV/Unil) and Jocelyne Bloch (CHUV/Unil) show that, after a few months of training, the patients were able to control previously paralyzed leg muscles even in the absence of electrical stimulation.
