The prestigious journal Nature on Wednesday published an extraordinary article by a team of scientists from the École Polytechnique Fédérale de Lausanne. The researchers have reported an experiment in which wireless neurostimulators have been placed into 3 paraplegic people’s spinal cords: the patients have been able to walk again thanks to electric impulses to the few nerve fibers still active in their spinal cords. The implanted neurostimulators have been developed by US-based group Medtronic and have firstly stimulated nerves to train and give power and strength to muscles. This has allowed patients to walk as early as one week after the neurostimulators had been implanted. The experiment shortly follows a similar one by a group of scientists at the University of Washington, reported by Nature Medicine.
