The RV-Rééduc project aims to develop innovative rehabilitation protocols for upper limbs in children and adolescents affected by traumatic arm or elbow injuries, or cerebral palsy. The goal is to restore or improve fine motor skills through interactive tasks involving virtual reality (VR). These protocols are designed to be engaging, incorporating movement-based tasks such as pointing, tracking, and intercepting virtual objects to stimulate upper limb motor functions and encourage neuroplasticity. Additionally, quality-of-life questionnaires are used to assess the effectiveness of the VR-based rehabilitation, potentially replacing more traditional, difficult practices in rehabilitation centers.
