ReWalk Robotics, Ltd. a leading manufacturer of robotic medical devices for individuals with lower limb disabilities, announced that the U.S. Food and Drug Administration ("FDA") has cleared the Company's ReStore soft exo-suit system for sale to rehabilitation centers across the United States. ReStore is the only soft exo-suit with FDA clearance, and is intended for use in the treatment of persons who have had a stroke with mobility challenges. Stroke is a leading cause of disability, which affects approximately 17 million people worldwide each year, and as many as 80% of people who have had a stroke will suffer from gait impairments.

In 2018, ReWalk launched a multi-center clinical study of the ReStore system across five of the country's leading rehabilitation centers, including MossRehab.  This data was submitted to the FDA in ReStore's 510(k) submission, and ReWalk expects to publish the results of the clinical study later this year.

"We are very encouraged by our initial experience and positive impact of ReStore in gait training for persons with stroke residual disabilities," said Moss Rehab's Chief Medical Officer Alberto Esquenazi, MD, who was one of the investigators in the multi-center trial.  "By training the patient walking pattern in a more correct way, the expectation is that the brain will re-learn and better restore the walking function lost after a stroke."

The ReStore system is comprised of a soft, garment-like design which connects to a lightweight waist pack and mechanical cables that help lift the patient's affected leg in synchronized timing with their natural walking pattern. The system provides targeted assistance to the patient during forward propulsion (plantarflexion) and ground clearance (dorsiflexion), two key phases of the gait cycle. The device also provides the physical therapists with extensive data during gait training with ReStore to inform strategies to optimize a patient's treatment and progress using real-time analytics.

"The idea of anchoring the body with textiles and flexible soft components is a fundamentally new way of applying assistance with a wearable robot," said Conor Walsh, a Professor of Engineering and Applied Sciences at the John A. Paulson Harvard School of Engineering and Applied Sciences and a Core Faculty member at the Wyss Institute for Biologically Inspired Engineering, who led a multi-disciplinary team to develop the soft exo-suit technology that has the ability to apply force to the body, but not restrict how a person moves. "This technology has broad potential, and we are currently testing additional concepts which can be applied to provide therapy and/ or mobility assistance for individuals with other diseases, such as multiple sclerosis and Parkinson's disease, and  also potentially be used by a person at home and in their community," Walsh continued.

The patented soft exo-suit technology was originally developed at Harvard University's Wyss Institute for Biologically Inspired Engineering where it also underwent initial clinical testing that demonstrated its potential to improve walking for stroke survivors. ReWalk and the Wyss Institute entered into a multi-year research collaboration agreement in 2016 which provides ReWalk access to future innovations that emerge from this collaboration and may be relevant to additional stroke products or other therapies.

ReStore is ReWalk's second major market segment, joining the ReWalk Personal 6.0—a robotic exoskeleton for home use by individuals with paralysis from a spinal cord injury—and the ReWalk Rehabilitation system, which allows for multiple patient uses through height and weight adjustments. "We believe the expansion to soft exo-suits gives ReWalk a diverse offering of innovative technologies and expands the Company's impact to millions of patients worldwide," said ReWalk CEO Larry Jasinski.
