Four years ago, architect Robert Woo was involved in a workplace accident that caused him to be paralyzed from his lower half down.
"I cannot walk, all my bodily functions -- digestive, bladder -- are all not functional from my injuries," Woo told the Associated Press.
But now, Woo is getting another shot at being able to walk. He is part of an experimental trial at Mt. Sinai hospital in New York City, where he is involved in testing an exoskeletal device that allows him to walk.
"Being able to take your first step is a phenomenal feeling -- I don't know how to describe it in words, really," Woo said to the AP.
The New York Daily News reported that Woo is one of six others who are testing the exoskeleton.
The Daily News explains how it works:
... [The exoskeleton] uses a combination of sensors and motors that physically move the legs. It's like a body brace with a backpack and gizmos that resemble shotguns near the knees. A physical therapist operates a remote control that makes the patient step when their body is properly aligned.
Earlier this year, exoskeleton technology helped student Austin Whitney to walk at his graduation from University of California, Berkeley. Whitney was paralyzed from the waist down after being involved in a drunk-driving accident.
