Lightweight Exoskeleton Lets Paraplegic Walk Again

On her website, former acrobat Silke Pan has a quote that says: "You are stronger than you ever expected!" She's had to be. After working as a professional acrobat for years, she was sidelined in 2007 when a fall left her unable to use her legs. Now she is walking again, thanks to a new modular lightweight exoskeleton. VOA's Kevin Enochs reports.
