“I’ll make the following claim: If a person has lost a leg in this Boston attack — if they’re motivated and generally healthy and reasonably athletic — they could, given current technology, they could walk or run across the finish line at the Boston Marathon this time next year.”
Making that bold statement is Hugh Herr, the renowned prosthetics and assistive technology expert who heads the Biomechatronics research group at MIT’s Media Lab (and is himself a double amputee). That’s what he said in response to my question about the future of the many victims who lost legs in Monday’s Marathon bombing. The current count, according to area hospitals, is 13 amputations.
What accounts for Herr’s optimism? Well, he’s already developed the world’s first powered ankle-foot prosthesis, which is being sold commercially and has been used by about 500 people. Also, Herr is a highly motivated guy: six months after his lower legs were amputated in 1982 after a climbing accident in which he got severe frostbite, he was walking — and climbing mountains again.
Indeed, Herr’s own artificial limbs are pretty powerful, with “…12 computers, five sensors and muscle-like actuator systems that able me to move throughout my day,” he told Terry Gross back in 2011.
These days, he said, speaking by phone from Spain, the long-term prognosis for patients with legs amputated below the knee, whether it’s one or both legs, “is very good.” For instance, the person will be able to “drive a car without hand controls, walk or run if they’re inclined,” he said.
