New device restores partial movement to four paralyzed men

Paralysis may not last forever anymore. In an experiment hailed as “staggering,” a team of researchers at the University of Louisville and the University of California-Los Angeles restored some voluntary movement to four men who were told they would never move their legs again. The finding, published online today by the journal Brain, upends understanding of the spinal cord and is likely to transform the lives of more than 1.2 million Americans who lack control over their lower limbs.
