Therapy assisting systems for neurological and orthopedic rehabilitation. Prof. Dr. Stefan Hesse and his team developed pioneering electromechanical and robotic devices to assist therapists in helping patients in their rehabilitation after stroke or incomplete paraplegia. Devices like the Gait Trainer GT I or the arm trainer Reha-Slide as well as the Reha-Slide Duo have been the first devices on the market. The unique new overground gait training system The FLOAT, developed in close collaboration with the Balgrist in Zurich, as well as the updates Gait Trainer GTII complete the comprehensive offering of therapy assisting devices for lower extremities to help increase therapy intensity with practical and easy-to-use devices for therapists and patients.
