Stroke is a medical emergency that occurs when not enough blood is able to reach brain cells, leading to many complications and, if not promptly treated, even death. It is the main cause of adult disability, with stroke survivors often experiencing paresis in one upper limb, which can make them unable to perform many self-care activities, resulting in a drop in their quality of life and a burden on their loved ones. By incorporating evidence from many previous studies on the topic and directly gathering opinions from experts in the field, this thesis' aim was to develop a Virtual Reality application, available through the Meta Quest 3 headset, that can help stroke survivors regain upper limb mobility by performing structured, highly repetitive tasks based on real life activities and inspired by the Graded Repetitive Arm Supplementary Program (GRASP).
