Twelve subjects with chronic motor complete cervical and
thoracic SCI have been trained to use ReWalkTM [39]. After eight
weeks of practicing, all subjects were able to walk independently
with crutches, without any other human assistance, for at least
50 meters continuously, for a period of at least 5–10 minutes
continuously and with velocities ranging from 0.03 m/s to 0.45 m/s.
Their gaits were fundamentally symmetric.
