Patient Justin Neff from Madison walks as he wears the ReWalk exoskeleton suit during an event at Sunnyview Rehabilitation Hospital on Thursday, Jan. 22, 2015, in Schenectady, N.Y.  The ReWalk exoskeleton suit uses a technology with motorized legs that power the knee and hip movements to help paraplegics and others with lower limb disabilities to walk again.  A computer based system uses motion sensors to control the leg movements in response to subtle changes in the upper body movements and shifts in balance.  Crutches are used for stability and a backpack worn by the patient holds the computer system and the battery that provides power to the suit.  Neff sustained his injury in October 2014 when he fell off a roof while working on it.  Neff arrived at Sunnyview in November.
