A rehabilitation system for neurological disorders, especially for the rehabilitation of patients being in a vegetative state or minimal conscious state, comprises at least two sensors adapted to measure two different physiological values of the patient and a stimulation generator. Initially predefined target signals determined and based on parameters relating to the injury are generated and, during a rehabilitation session, compared with the measurement signals to drive the stimulation generators delivering sensory stimulation to the patient as feedback. The controlling processor is adapted to change the predefined target signals during a rehabilitation session based on the development or changes of the measurement signals of the different physiological values, to enable a faster and better improvement of the alertness of the patient.
