METHOD AND SYSTEM FOR TRAINING REHABILITATION OF COGNITION AND EXERCISE BASED ON BIO SIGNAL}

The present invention relates to a method for performing rehabilitation training using an EMG signal which is an example of a biosignal according to a user's movement.

The number of stroke patients is rapidly increasing with the recent increase in the elderly population due to aging. Stroke is mostly accompanied by movement and cognitive impairment symptoms, and older people have symptoms of difficulty in using the body due to aging and a decrease in intellectual ability. In particular, cognitive impairment due to stroke and traumatic brain disease causes abnormalities in the patient's attention, memory, perception, problem solving ability, makes it difficult to carry out daily life movements, and furthermore, it is an important obstacle to performance of family, social and professional life. do. The importance of rehabilitation therapy is increasing to treat this, and there is a lot of research for effective rehabilitation therapy.

EMG signal processing has been actively studied for human skeletal muscle analysis, diagnosis, and behavioral mimics in fields such as diagnostic medicine, sports science, and rehabilitation engineering. In particular, bio-mechanical interface system technology using EMG signals is an important core of robot technology. Recently, EMG signals have been used for the purpose of rehabilitation of patients suffering from physical disabilities using prostheses, prostheses and wheelchairs or human computer interface (HCI) technology.

1 is a block diagram showing the configuration of the exercise and cognitive rehabilitation training system according to an embodiment of the present invention.

Referring to FIG. 1, the exercise and cognitive rehabilitation training system 100 (hereinafter, referred to as a “rehabilitation training system”) includes an EMG module 110, a signal processor 120, a central unit 130, an interface unit 140, and a database. 150 may be included.

The EMG module 110 is attached to the body of the user to detect the movement of the user to obtain an EMG signal. The EMG module 110 may be attached anywhere in the body part of the user where the EMG signal can be obtained from the user. In an embodiment, the EMG module 110 may be carried in a carry type and may be designed as a cuff type that may be attached to or detached from the body of the user.

The signal processor 120 may perform signal processing such as amplification or filtering on the obtained EMG signal. The signal processor 120 may amplify the acquired EMG signal when the obtained EMG signal is weak, and perform filtering to remove noise when the amplified EMG signal includes a lot of noise.

The central unit 130 compares the processed EMG signal with a threshold and outputs a key operation signal corresponding to the result of the comparison. To this end, the central unit 130 may include a controller 131, a setting unit 132, and an adjusting unit 133.

The setting unit 132 may receive a threshold associated with the exercise ability of the user and receive a key corresponding to the input threshold. Since the exercise ability is different for each user, the setting unit 132 may receive the threshold value from the user in consideration of the exercise ability of the user. The threshold is also related to the number of corresponding keys. For example, when there are four keys to be set, the setting unit 132 may receive four thresholds. For example, the first threshold may correspond to the first key, the second threshold may correspond to the second key, the third threshold may correspond to the third key, and the fourth threshold may correspond to the fourth key.

As described above, each key corresponding to each threshold may be stored in the database 150.

The controller 131 may compare the signal-processed EMG signal with the threshold, identify a key corresponding to the compared threshold, and output a key operation signal for manipulating the identified key. For example, when the identified key is the first key, the controller 131 may output a first key operation signal for operating the first key. In this case, the first key may be a direction key in an "up" direction or may be a numeric key '1'. In addition, the key manipulation signal is a signal associated with the game, and may be a signal such as moving in the up / down / left / right directions or pressing a numeric key.

The adjusting unit 133 may extract the directional pattern and the strength of the muscle force associated with the user's exercise method, and adjust the threshold in consideration of the extracted directional pattern and the strength of the muscle force. Like the exercise ability, the exercise method may be different according to the state of the user. Accordingly, the adjusting unit 133 may adjust the threshold value according to the extracted directional pattern and strength of the muscle in consideration of the user's exercise method.

The interface unit 140 transmits the output key manipulation signal to the electronic device to control the electronic device. The electronic device may include a device such as a smart phone, a smart TV, a PC, a tablet PC, and the like. For example, the interface unit 140 may transmit the key manipulation signal to the electronic device through wireless communication such as Zigbee, Bluetooth, lan communication, or the like. The electronic device may input a character or move a key in an up / down / left / right direction by the key manipulation signal.

In an embodiment, the central unit 130 may calculate the number of times of obtaining an EMG signal higher than the threshold value based on the processed EMG signal, or determine a reaction time of an electronic device or a reaction time of a user in association with the EMG signal. Average or calculate the variance.

The database 150 may store the user's personal information and the number of times the EMG signal is acquired higher than the threshold according to the user's movement during the rehabilitation training, the average and the variance of the response time associated with the EMG signal. In addition, it can store the reaction time and the average and variance of the score obtained when playing the game including the cognitive rehabilitation therapy.

The interface unit 140 transmits a key operation signal based on an EMG signal to the electronic device through wireless communication between the electronic device and the EMG module 110, receives the transmitted key operation signal, and grasps the intention of the user. The appropriate key can be activated.

The database 150 acquires a game content for performing cognitive rehabilitation treatment such as attention training, space-time perceptual training, memory training, and the like by using a key manipulation signal operated by the interface unit 140, the user's name, age, ID, and EMG. Personal information of the user, including the location (return) and the like can be stored.

2 is a view showing an example of the EMG module attachment position and wrist classification operation according to an embodiment of the present invention.

Referring to FIG. 2, the EMG module may be attached to a wrist 210 of a user who may sense movement of a user muscle. For example, an EMG module of four channels (ch1 to ch4) is attached to the forearm muscle of the user's body part, and the EMG signal for movements of the upper 220, the right 230, the lower 240, and the left 250 of the wrist. The intention of the user can be distinguished by detecting the. The body part of the user to which the EMG module is attached may be applied to all parts of the body that can distinguish the muscle direction, not limited to the forearm muscle.

Therefore, the central unit may output a key manipulation signal for inputting the 'up' direction key or the numeric key '1' to the electronic device when the user receives the EMG signal for raising the wrist up.

When the user turns the wrist to the right (320), the 'right' direction key 321, or the numeric key '2 (322)' may be matched. Therefore, when the user receives an EMG signal for turning the wrist to the right, the central unit may output a key manipulation signal for inputting a 'right' direction key or a numeric key '2' to the electronic device.

When the user lowers the wrist 330, the 'down' direction key 331, or the numeric key '3 332' may be matched. Therefore, when the user receives the EMG signal for lowering the wrist down, the central unit may output a key operation signal for inputting the 'down' direction key or the numeric key '3' to the electronic device.

When the user turns the wrist to the left (340), the 'left' direction key 341, or the numeric key '4 (342)' may be matched. Therefore, when the user receives an EMG signal for turning the wrist to the left, the central unit may output a key operation signal for inputting a 'left' direction key or a numeric key '4' to the electronic device.

According to an exemplary embodiment, the key may be matched with various keys as well as the direction of the keyboard or the numeric keys, and may substitute for a mouse, a keypad, and a touch sensor.

Referring to FIG. 4, the user may move a star located at 410 to the 420 position by moving his wrist in a 'right upward direction'. That is, the EMG signal according to the user's wrist movement can be matched with the arrow direction key. Therefore, the central unit may output a key operation signal for inputting the 'right' and 'up' direction keys when the user receives an EMG signal that continuously rotates the wrist to the right and upward. In this case, the star located at 410 on the screen may be moved to the position of 420 according to the manipulation of the electronic device.

For reference, in FIG. 4, visual stress training can be implemented in a game type in which a direction of muscle movement is detected as an EMG signal and a given figure is matched to a frame of a picture drawn at another position.

5 is a diagram illustrating an example of playing a game using an EMG module according to an embodiment of the present invention.

Referring to FIG. 5, the central unit may match an EMG signal according to a user's wrist movement with a direction key. The central unit may output a key manipulation signal for inputting an 'up' key when the EMG signal of the user raising the wrist upward in the '①' area. Subsequently, the central unit may output a key operation signal for inputting the 'left direction key' when the EMG signal for turning the wrist to the left in the area '②' is input. In addition, the central unit may output a key operation signal for inputting the 'up direction key' when the EMG signal of the user raising the wrist upward in the '③' area.

In this way, the central unit may play a game of starting the identifier controlled by the user from the start point of the electronic display device to the marked destination point using the EMG signal measuring the direction of movement in real time.

The electronic device may provide the first screen 610 to the user for a predetermined time and then provide the second screen 620. In this case, the central unit may match the EMG signal according to the movement of the user's wrist with the numeric keys 312, 322, 332 and 342. When the second screen 620 is provided, when the user raises the wrist upwards, the central unit may output a key operation signal for inputting the numeric key '1' according to the EMG signal raised in the 'upward' direction.

That is, the user may find a picture 625 that is the same as the picture 610 first provided, and perform the game by performing a wrist movement 310 corresponding to the number key 312 such as the number 621 shown in the picture. .

In addition, the game may be associated with cognitive rehabilitation therapy, such as attention training games, space-time perceptual training games, memory training games.

8 is a diagram illustrating an example of a result of performing rehabilitation treatment using an EMG module according to an embodiment of the present invention. For reference, FIG. 8 illustrates the number of occurrences of EMG that is equal to or greater than a threshold of a user when a cognitive rehabilitation game is performed. As shown, it may be calculated by the cognitive rehabilitation game shown in FIG. 4 to FIG. 7B. After the user performs each cognitive rehabilitation game, the database may store the amount of exercise for playing the game. In this case, the interface unit quantitatively feeds back the stored exercise amount, so that the user can quantitatively confirm the effect of repeating the rehabilitation treatment.

9 is a view showing another example of the results of the rehabilitation treatment using the EMG module according to an embodiment of the present invention.

For reference, FIG. 9 is a graph showing a response time and an acquisition score of a user when a cognitive rehabilitation game is performed, and may be calculated by the cognitive rehabilitation game shown in FIGS. 4 to 7B. After the user performs the cognitive rehabilitation game, the time taken to achieve the goal of the game and the score obtained by the user may be fed back as quantitative and objective data and stored in a database.
