A rehabilitation system is provided with a brain wave measurement device (10), a presentation device (20), an electric tool (30), and a control device (50). The brain wave measurement device (10) supplies a measurement result to the control device (50). The control device (50) is configured so as to present information to a patient via the presentation device (20) and apply at least one of electrical stimulation and mechanical stimulation to the patient via the electric tool (30). The control device (50) extracts an ERD signal that is related to an exercise plan from a brain wave measured by the brain wave measurement device (10) and changes the control of the electric tool (30) when it is determined on the basis of at least the ERD signal that an activation of the motor cortex that is associated with the exercise plan has occurred.
