The purpose of the study is to test the technical functionality, safety, and feasibility of a bimanual robotic exoskeletal platform and associated serious games in order to offer information on technological and functional advances that will be included in the device's finalization. In addition, a secondary goal will be to assess the therapeutic effects of a rehabilitation therapy based on the bimanual configuration, comparing it to a unimanual treatment delivered on the same platform (using the specific configuration).
Inclusion Criteria: * height between 150 and 190 cm; * weight not exceeding 130 kg; * ischemic injury; * first cortical and supra-tentorial event; * moderate motor deficit of the upper limb (score on the Fugl-Meyer Assessment - Upper Extremity between 29 and 42); * time since stroke event between 1 and 6 months; * trunk control test score greater than or equal to 48; * healthy bone density and skeleton that does not suffer from unhealed fractures. Exclusion Criteria: * Relevant medical comorbidities (severe neurological diseases, cardiovascular diseases, diabetes / unstabilized hypertension); * Cognitive impairment that prevents understanding of the exercises administered; * Unavailability to provide informed consent; * Pregnant women; * Severe spasticity (Ashworth 4); * Major muscle contractures; * Excessive asymmetry in the length of the arms; * Upper limb prostheses; * Excessive joint limitations that make it difficult or painful to use the device; * Use of pacemakers or implantation of active devices; * Patients who already participate in another clinical study or who are already undergoing another similar robotic rehabilitation treatment.
