“Among the participants was the inventor of the suit, Dr. Amit Goffer. Goffer is himself a quadriplegic who became frustrated by the outdated wheelchair and wanted to create something that would allow people with spinal cord injuries to walk again. ‘What’s unique about ReWalk is that behind the left elbow of the user is a motion sensor that picks up a user’s movement when they walk,’ Jasinski said. ‘That is attached to a computer that can replicate human gait to create a non-robotic walking step.’ Most other types of technologies cause an unnatural, stiff walk closer to a robot than to the way humans stride. ReWalk helps to create a more natural and human-like step.”
