A Hybrid Robotic System for Arm Training of Stroke Survivors: Concept and First Evaluation
Description: This work describes a hybrid robotic system for arm recovery after stroke developed within the European project RETRAINER. The RETRAINER system combines EMG-triggered Functional Electrical Stimulation with a passive exoskeleton for upper limb suspension. A first validation on 7 post-acute stroke survivors is provided. All patients showed improved motor functions after the training program and were able to perform the exercises faster, smoother and with a wider range of motion. Overall, RETRAINER is usable, highly customizable, allows to monitor the daily performance and requires low supervision of the therapist, thus becoming an interesting option for arm recovery after stroke.
