GAME-BASED REHABILITATION SYSTEM COMBINE FUNCTIONAL ELECTRICAL STIMULATION AND BRAIN-COMPUTER INTERFACE TECHNIQUE TO MAXIMIZE ACTIVATION OF MIRROR NERVE CELL AND ITS CONTROL METHOD}

The present invention relates to a rehabilitation system and a control method thereof, and to a game-type rehabilitation system and a control method thereof in which functional electrical stimulation to maximize the activation of mirror neurons and brain-computer interface (BCI) technology are combined.

In general, patients with brain diseases having a deficit in motor ability are in most cases unable to control the paralyzed muscles with their own will, and methods of helping such patients rehabilitate include physical therapy, drug therapy, and surgery. In particular, in rehabilitation training using physical therapy, it has been reported that the effect of rehabilitation training is high when active treatment is performed by the patient's will. However, for patients with limited movement due to muscle paralysis, such rehabilitation training There is a problem that must be made passively by a physical therapist.

On the other hand, in order to increase the effect of rehabilitation training, there is a treatment method using stimulation of the patient's mirror nerve cells. This is meaningful in that it is not passive treatment by a physical therapist, but active rehabilitation training performed by the patient looking at a specific target and performing actions. Mirror neuron refers to a cell that causes the same reaction in the observer's body just as the observer actually behaves, just by seeing the actions of others, not directly experienced by them. As a rehabilitation training that applies this, there is a method of showing a video including a motion of a specific object in order to activate the patient's mirror nerve cells. This method is for patients who cannot operate with their own will due to brain damage. Ee, just seeing the behavior of others affects the patient's body system as if the patient himself behaves itself.

In addition, recently, research related to rehabilitation using the patient's EEG is being conducted. In particular, BCI (Brain-Computer Interface) refers to a device that transmits EEG to a computer. Using this BCI technology, human and computer The development of the rehabilitation system field using communication is becoming active.

In other words, in the BCI technology using SSVEP, when a user sees light flickering at a specific frequency, SSVEP is generated in the back of the user's brain, and SSVEP measured through an EEG measurement device installed in the user's head is input to the computer. , EEG can be transmitted to the computer.

1 is a diagram showing an example of a system using a conventional SSVEP. As shown in FIG. 1, SSVEP is detected from the user's EEG, and the detected EEG is transmitted to the computer using light that flickers at a specific frequency on the screen.

Each flickering light has a predetermined signal, and it is a system that can remotely control a device corresponding to the signal of the light that the user is watching. Since the system using such a flickering light only uses flickering light, it is difficult for the user to be interested in this, and there is a problem in that the concentration is low. As prior art related to such a system using SSVEP, Patent Publication No. 10-2014-0075049 (name of the invention: concentration evaluation method and apparatus for applying the same), Registration Patent No. 10-1431203 (name of the invention: EEG And a brain machine interface device and method for intent recognition using a method).
