The sixth generation ReWalk Personal Exoskeleton was created to aid individuals who are disabled in their lower limbs. It is the only FDA-cleared exoskeleton in the United States and is used for both personal and clinical rehabilitation use.
History of ReWalk
The ReWalk exoskeleton has gone through extensive laboratory and clinical testing, making it the most studied exoskeleton of its kind. Recently, ReWalk and Wyss Institute announced a five-year collaboration to design a “soft suit” system for patients with MS, stroke, and severely limited mobility. The current suit is rigid and intended for use by patients with spinal cord injury; the new suit consists of cables that are connected to fabric pieces that attach to the lower limbs. Although ReWalk will commercialize the soft suit for stroke patients first, MS patients with lower limb disability are soon to follow.
How ReWalk Works
ReWalk was designed to help patients stand, walk, turn, and, though the feature is not yet available in the United States, ascend and descend stairs. The technology encompasses a wearable brace support, a computer-based control system, and motion sensors. This system allows patients to walk independently and with a controlled, natural gait.
When patients are using ReWalk, the exoskeleton detects changes in the center of gravity. The system senses when a patient tilts forward and subsequently initiates a step. A series of changes in body position provides the steps necessary for a natural gait. People who use ReWalk have written in testimonials that they are happy with the walking experience the device provides.
