Human exoskeleton suit helps paralyzed people walk

"HAIFA, Israel (Reuters) - paralyzed for the past 20 years, former Israeli paratrooper Radi Kaiof now walks down the street with a dim mechanical hum.

"That is the sound of an electronic exoskeleton moving the 41-year-old's legs and propelling him forward -- with a proud expression on his face -- as passersby stare in surprise.

"The device, called ReWalk, is the brainchild of engineer Amit Goffer, founder of Argo Medical Technologies, a small Israeli high-tech company.

"Something of a mix between the exoskeleton of a crustacean and the suit worn by comic hero Iron Man, ReWalk helps paraplegics -- people paralyzed below the waist -- to stand, walk and climb stairs."
