摘要
三名瘫痪多年的病人又能够重新走路了,这要归功于植入他们脊柱的神奇的电子装置。;A motorcycle accident several years ago left Michel Roccati paralyzed from the waist down. Now, years after his injury, he has regained the ability to walk thanks to electrodes (电极) implanted on his spine.“I am free,” Roccati says.“I can walk wherever I want to.”
