BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game-based rehabilitation system using a brain-computer interface (BCI), and more particularly, to a rehabilitation system that displays a game image and a signal image disposed around the game image, An EEG analyzing device for analyzing a user's EEG acquired from the EEG acquisition device, and an EEG analyzing device for analyzing the user's EEG acquired by the EEG analyzing device, And a control device for controlling a game image of the display device according to a result corresponding to brain waves, wherein the user activates the mirror nerve cell according to the motion for activating the mirror neuron displayed by the signal image, As shown in Fig. The present invention relates to a method of controlling a rehabilitation system using a brain-computer interface (BCI), and more particularly, to a method of controlling a rehabilitation system using a brain-computer interface (BCI) (2) acquiring a brain wave of a user corresponding to a signal image displayed in the step (1)； (3) acquiring a brain wave corresponding to a signal image displayed in the step ) Analyzing the brain waves of the user obtained in the step (2), and (4) analyzing the brain waves of the display device according to the results corresponding to the brain waves analyzed in the step (3) And controlling the image, wherein rehabilitation training is performed using the activation of the user's mirror nerve cell according to the motion for activating the mirror nerve cell represented by the signal image, . According to the game-based rehabilitation system and the control method of the rehabilitation system using the brain-computer interface (BCI) proposed in the present invention, unlike the conventional system using the SSVEP, which uses the flashing light, By using a moving image capable of activating the mirror nerve cell as the signal image to be included, it is possible to increase the concentration o
