FASTER, PLEASE: Toyota shows machines to help sick, elderly move. “Eiichi Saitoh, a professor in rehabilitation medicine, demonstrated the ‘walk assist’ device on Tuesday, strapping the computerized metallic brace onto his right leg, which was paralyzed by polio. He showed reporters at a Toyota facility in Tokyo how the brace could bend at the knee as needed, allowing him to walk more naturally and rise from a chair with greater ease than the walker he now uses. Wearing a backpack-like battery, Saitoh walked up and down a flight of stairs, smiling with delight.”
