Robotic suit helps paralyzed walk
Story Highlights

Robotic suit developed in Israel helps paraplegics walk again

Device gives paralyzed people alternative to using a wheelchair

Invention currently in clinical trials and could be on the market by 2010

LONDON, England (CNN) -- A new robotic suit could transform the lives of paralyzed people, giving them the ability to walk again.

The invention, known as ReWalk, acts like a kind of exoskeleton. It consists of lightweight, motorized leg supports and an assortment of intricate motion sensors.

Users wear a backpack that holds a computerized control box which helps the medical device recognize when a step needs to be taken.

"Standing changes my whole environment. I don't have to look from the bottom up. Now I am eye to eye with everybody," Radi Kaiof, who has used the device, told CNN.

Kaiof, a former Israeli soldier, was paralyzed from the waist down 20 years ago. He doesn't have feeling in his legs but is still able to move with the use of the robotic suit.
