Specific details for implementing the invention

[0033] The present invention is susceptible to various modifications and may have various embodiments; specific embodiments are illustrated in the drawings and described in detail in the detailed description. However, this is not intended to limit the invention to specific embodiments, and it should be understood that the invention includes all modifications, equivalents, and substitutions that fall within the spirit and scope of the invention. Similar reference numerals have been used for similar components in the description of each drawing.

[0034] Terms such as first, second, A, B, etc., may be used to describe various components, but said components shall not be limited by said terms. These terms are used solely for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be named the second component, and similarly, the second component may be named the first component. The term "and / or" includes a combination of a plurality of related described items or any of a plurality of related described items.

[0035] When it is stated that one component is "connected" or "connected" to another component, it should be understood that while it may be directly connected or connected to that other component, there may also be other components in between. On the other hand, when it is stated that one component is "directly connected" or "directly connected" to another component, it should be understood that there are no other components in between.

[0036] The terms used in this application are used merely to describe specific embodiments and are not intended to limit the invention. The singular expression includes the plural expression unless the context clearly indicates otherwise. In this application, terms such as "comprising" or "having" are intended to specify the existence of the features, numbers, steps, actions, components, parts, or combinations thereof described in the specification, and should be understood as not precluding the existence or addition of one or more other features, numbers, steps, actions, components, parts, or combinations thereof.

[0037] Unless otherwise defined, all terms used herein, including technical or scientific terms, have the same meaning as generally understood by those skilled in the art to which the present invention pertains. Terms such as those defined in commonly used dictionaries should be interpreted as having a meaning consistent with their meaning in the context of the relevant technology, and should not be interpreted in an ideal or overly formal sense unless explicitly defined in this application.

[0038] In addition, in the electrical stimulation device and the method for controlling the electrical stimulation device using the same according to the embodiments of the present invention, electrical stimulation refers to a therapeutic act of sequentially applying electrical stimulation of an appropriate intensity to a paralyzed muscle to enable it to perform a given function.

[0039] Electrical stimulation may include functional electrical stimulation and neuromuscular electrical stimulation. Functional electrical stimulation refers to providing electrical stimulation that moves muscles to help them perform their proper functions.

[0040] Furthermore, neuromuscular electrical stimulation refers to preventing or delaying muscle atrophy that occurs after muscles are severed from the upper motor nervous system, thereby preventing the degeneration of muscle function and retraining the muscles to maintain their original motor functions.

[0041] The components for functional electrical stimulation consist of electrodes, stimulators, and controllers. Unipolar and bipolar electrodes are used, and depending on the attachment method, they can be classified into surface electrodes used for transdermal stimulation, implantable electrodes inserted subcutaneously or into muscles, and implantable electrodes.

[0042] In addition, various electrical stimulation modulation therapies are possible depending on the type of disease. However, for patients to wear and utilize the device directly without the supervision of medical staff, a wearable rehabilitation device based on surface electrode attachment, rather than an insertable or implantable type, may be advantageous.

[0043] Accordingly, a preferred embodiment of the present invention regarding an electrical stimulation-based wearable rehabilitation device will be described in more detail below with reference to the attached drawings.

[0044] In order to facilitate an overall understanding of the present invention, the same reference numerals are used for identical components in the drawings, and redundant descriptions of identical components are omitted.

[0046] FIG. 1 is a block diagram of an electric stimulation device according to an embodiment of the present invention.

[0062] The controller (1500) may be provided as an integral part of the pad (1000) or as a separate, independent component.

[0063] According to the embodiment, the controller (1500) can be provided as various computing modules such as a computing board, mobile, tablet PC, desktop PC, etc.

[0064] The controller (1500) will be described in more detail by configuration with reference to Figure 3 below.

[0066] FIG. 3 is a block diagram of a controller within an electric stimulation device according to an embodiment of the present invention.

[0067] Referring to FIG. 3, the controller (1500) within the electrical stimulation device may include a memory (100) that stores at least one command and a processor (200) that executes at least one command of the memory.

[0068] Additionally, the controller (1500) within the electric stimulation device (1000) may further include a transmitting / receiving device (300), an input interface device (400), an output interface device (500), a storage device (600), etc.

[0069] According to an embodiment, each component (100, 200, 300, 400, 500, 600) included in the electric stimulation device (1000) can communicate with each other by being connected by a bus (700).

[0070] Among the above configurations (100, 200, 300, 400, 500, 600, 700) of the controller (1500), the memory (100) and the storage device (600) may be configured with at least one of a volatile storage medium and a non-volatile storage medium.

[0072] According to an embodiment, at least one command may include a command to acquire user information, a command to output the user information to assist in wearing the pad on a specific body part, a command to select a specific pattern array in which at least one cell is patterned in a clustered or dispersed form from a pattern map when an operation signal is received from the outside, and a command to set an initial setting value of the sensor based on the pattern array, and a command to measure the degree of muscle response according to the initial setting value and readjust the setting value of the sensor.

[0073] The processor (200) may mean a central processing unit (CPU), a graphics processing unit (GPU), or a dedicated processor on which methods according to embodiments of the present invention are performed.

[0074] As previously described, the processor (200) can execute at least one program command stored in memory (100).

[0075] According to an embodiment, the processor (200) can execute at least one instruction according to at least one instruction stored in memory (100).

[0077] The input interface device (400) may be an interface device for receiving operation signals from a user. For example, the input interface device (400) may receive an input signal based on button input or an input signal based on voice recognition.

[0078] The electric stimulation device according to an embodiment of the present invention has been described above.

[0079] Below, I will explain an electrical stimulation-based electrical stimulation device control method executed by the processor operation of the controller within the electrical stimulation device.

[0081] FIG. 4 is a flowchart for explaining an electric stimulation-based electric stimulation device control method according to an embodiment of the present invention.

[0082] Referring to FIG. 4, the processor (200) of the controller (1500) in the electrical stimulation device can obtain user information (S1000).

[0083] According to one embodiment, the processor (200) can utilize existing user information previously stored in the storage device (600) as user information.

[0084] According to another embodiment, if there is no user information pre-stored in the storage device (600), the processor (200) can receive and obtain at least one piece of new information from the user.

[0085] Afterwards, the processor (200) can store at least one piece of information newly received from the user in the storage device (600).

[0086] The processor (200) can output user information by executing an output interface device (500) (S2000). Accordingly, the user can wear the pad in an appropriate position based on the output user information.

[0087] Subsequently, the processor (200) can receive an operation signal from the user. Accordingly, the processor (200) can set an initial setting value for at least one sensor for the operation of the pad (S3000). In other words, when the processor (200) receives an operation signal from the user, it can set the initial setting value and the pattern array of the pattern array, the measurement sensor, and the stimulation sensor.

[0088] The step of setting the initial setting value of the above sensor will be explained in more detail with reference to Figure 4 below.

[0090] Figure 5 is an image of the interaction between a pad and a controller in an electric stimulation-based electric stimulation device control method according to an embodiment of the present invention.

[0091] Referring to FIG. 5, the processor (200) can be linked with the pad by the transmitting and receiving device (300). Accordingly, the processor (200) can set the initial setting value of the sensor.

[0092] The step of setting the initial setting value of at least one sensor within the pad above will be explained in more detail with reference to Fig. 6 below.

[0094] FIG. 6 is an image illustrating a method for setting an initial setting value of a sensor among an electrical stimulation-based electrical stimulation device control method according to an embodiment of the present invention.

[0095] Referring to FIG. 6, the processor (200) can specify a cell area to receive electrical stimulation using a pattern map. In other words, the processor (200) can set a muscle measurement area to receive electrical stimulation using a pattern map.

[0096] Here, the pattern map may include at least one pattern array (P1, P2, P3) in which at least one cell containing a measurement sensor and a stimulation sensor is provided in a clustered or dispersed form.

[0097] The processor (200) outputs at least one pattern array (P1, P2, P3) to an output interface device (500) so that one of the pattern arrays can be selected by a user.

[0098] Subsequently, the processor (200) can fine-tune the muscle response measurement area and the current intensity value of the electrical stimulation for at least one sensor included in the pattern array based on the selected pattern array.

[0099] According to one embodiment, the processor (200) can set an appropriate current intensity value for electrical stimulation by gradually increasing the current intensity of the electrical stimulation from a low intensity to a high intensity and measuring the degree of response of the muscle accordingly.

[0100] According to another embodiment, the processor (200) can set a measurement target area by gradually expanding the electrical stimulation application area based on a selected pattern arrangement and measuring the degree of muscle response.

[0101] Subsequently, the processor (200) can store at least one measured value in the storage device (600). According to an embodiment, the processor (200) can classify and store at least one measured value by user. In other words, at least one measured value can be constructed as individual user data.

[0103] Referring again to FIG. 4, the processor (200) can continuously measure the degree of the user's muscle response measured from the measurement sensor.

[0104] Subsequently, the processor (200) can readjust the muscle response measurement area and the current intensity of the electrical stimulation by comparing a specific reference value and a measured value (S4000). In other words, the processor (200) can control the set value of the sensor in real time by comparing a specific reference value and a measured value.

[0105] According to one embodiment, a specific reference value may be provided as a Manual Muscle Testing (MMT) rating table for the wrist. Accordingly, the processor (200) can adjust the current intensity of the electrical stimulation to treat the damaged muscle in a specific area according to the MMT rating table.

[0106] According to another embodiment, the processor (200) can gradually increase the intensity of the electrical stimulation and readjust the current intensity of the electrical stimulation by analyzing the degree of change in the muscle response measurement value accordingly.

[0108] Conventional electrical stimulation devices have the disadvantage that it is difficult to dynamically control the set value during operation of the device. In other words, conventional electrical stimulation devices have the disadvantage of having to maintain the reference point and the user's range of motion value, which are initially set before use, until the end of treatment.

[0109] However, the electric stimulation device (1000) according to an embodiment of the present invention can provide a high-performance, high-efficiency, and high-convenience electric stimulation device that reflects the user's recovery ability in real time by measuring and analyzing the degree of muscle response of the user in real time even during treatment and dynamically adjusting the measurement area and the current intensity of the stimulation.

[0111] Referring again to FIG. 4, the processor (200) can store at least one real-time measurement data and setting data acquired during treatment in a storage device (600) when treatment is finished (S5000).

[0112] Subsequently, the processor (200) can generate a learning model or update a pre-generated learning model based on at least one data stored in the storage device (600) (S6000). In other words, the processor (200) can utilize the real-time measurement data and setting data as training data to generate or update the user's individual learning model.

[0113] Accordingly, the electrical stimulation-based electrical stimulation device control method according to an embodiment of the present invention can provide customized treatment for each user.

[0115] The above describes an electric stimulation device according to an embodiment of the present invention and a method for controlling the electric stimulation device using the same.

[0116] An electric stimulation device according to an embodiment of the present invention and a method for controlling an electric stimulation device using the same comprises a plurality of cells including at least one sensor, a pad worn on a part of a user's body to apply electric stimulation to damaged muscles in a specific area, and a controller that dynamically controls the operation of the at least one sensor to adjust the current intensity and application area of ​​the electric stimulation applied to the pad, thereby providing a high-performance, high-efficiency, and high-reliability electric stimulation device and a method for controlling an electric stimulation device using the same, which continuously measures and analyzes the degree of response of the muscles in a specific area to electric stimulation by applying various pattern arrangements in which measurement points and stimulation points are clustered or dispersed, and dynamically resets the measurement range and the current intensity of the electric stimulation when the degree of muscle response is measured to be below a certain standard, thereby improving the rehabilitation effect of the user.

[0118] The operation of the method according to the embodiments of the present invention can be implemented as a computer-readable program or code on a computer-readable recording medium. A computer-readable recording medium includes all types of recording devices in which data that can be read by a computer system is stored. Additionally, the computer-readable recording medium may be distributed across networked computer systems, allowing the computer-readable program or code to be stored and executed in a distributed manner.
