Cover Story: This study proposes an innovative protocol for robot-assisted lower-limb rehabilitation for patients with hemiparesis. It integrates dual interaction with the patient, using mirror therapy and a self-adaptive control system based on EMG. The system features a robotic platform dedicated to lower-limb rehabilitation, integrated with an immersive virtual reality (VR) environment, which includes a digital twin of the robot, a patient avatar, and virtual targets. Mirror therapy is implemented using inertial sensors placed on the healthy limb to capture movements in real time. The goal is to stimulate neuroplasticity and increase engagement, and laboratory tests show motor improvements and support the potential of personalized therapies based on the combination of robotics and VR. View this paper
