Leg-Paralysis Sensing, Stimulation Device Steps Up 20

AndreV writes "After 30 years of development, a device developed at Simon Fraser University that assists people to walk who have paralysis in one leg will soon be on the market in Europe and, eventually, in the US and Canada. The pacemaker-like Neurostep uses nerve cuffs to sense and stimulate nerve activity in the paralyzed leg, allowing greater mobility for those suffering from neurological disabilities such as stroke, multiple sclerosis, spinal cord injury, or cerebral palsy. About the size of a cell phone, the 'brain' integrates three digital modules: the neurosensing module (receives nerve impulses), real-time adaptive control module (interrogates the signals and identifies physical events), and neurostimulation module (delivers stimulation to the target nerve). It was recently approved for use in Europe, and they are working to begin clinical trials and introduce the device in the US."
