Some of that technology, specifically an exosuit for post-stroke gait retraining, received support from the Wyss Institute for Biologically Inspired Engineering, and was licensed and commercialized by ReWalk Robotics. These episodes prevented him from walking around his community and forced him to rely on a scooter to get around outside. Without any special training, the patient was able to walk without any freezing indoors and with only occasional episodes outdoors. “Because we don’t really understand freezing, we don’t really know why this approach works so well,” said Ellis. “But this work suggests the potential benefits of a ‘bottom-up’ rather than ‘top-down’ solution to treating gait freezing.
