Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pain therapy apparatus for body symmetry,

The present invention relates to a pain treatment apparatus, and more particularly, to a pain treatment apparatus for replacing an image of a surgical site with an image of a normal site for a disease occurring only on one side of an externally symmetrical body such as a knee joint The present invention relates to a pain treatment apparatus for a physical disease, which is an external symmetry for treating a patient's pain by confusing a cognitive function of a patient by allowing a patient to view the symmetrical image in real-time.

A knee joint refers to a knee joint and refers to a joint consisting of the thigh bone (femur), the shin bone (tibia), and the anterior bone of the knee (patella). The knee plays an important role in the process of walking or utilizing the knee.

In recent years, however, knee joints are damaged or destroyed due to various causes, so that the knees are not straightened or bent, so that they can not be normally walked. For example, an anomaly may develop in a knee when trauma occurs during aggravated exercise, degenerative arthritis due to aging, rheumatoid arthritis, or an O-shaped or X-shaped leg.

To treat these joint anomalies, a total knee arthroplasty is performed. Total knee arthroplasty refers to the technique of removing knee joints and inserting artificially created knee joints. However, after such knee arthroplasty, a large number of patients were present and felt a lot of pain, which was a burden on the patient who underwent the procedure.

Conventionally, analgesics and other medicines are mostly used as methods for reducing the pain of a patient. However, the method of inhibiting analgesia due to the drug may have an adverse effect on the patient ' s body function by taking more and more drugs because the drug resistance lowers the effect. In this case, there is a limit to the method for reducing the pain of the patient.

Nevertheless, since there is no proper alternative to the pain medication currently used, most of the patients who have undergone the knee surgery rely on the medication, though the above problem is recognized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Although the embodiments of the present invention described herein are directed to patients with knee joints treated through rehabilitation after knee surgery, the present invention is not limited thereto. That is, the present invention can be commonly applied to all diseases that can be treated by mirror therapy if a disease occurs in any part of the body, which is outwardly symmetrical.

FIG. 1 is an exemplary view showing an apparatus for treating a pain for an external symmetric body disease according to a first embodiment of the present invention, and FIG. 2 is a block diagram illustrating the image processing module shown in FIG. 1. Referring to FIG.

As shown in FIG. 1, a pain treatment apparatus (hereinafter, referred to as a "pain treatment apparatus") for external physical symmetry of the present invention includes a chair 100 and a chair 100 And a treatment unit 200 provided.

In the chair 100, a curtain 110 having a predetermined length is formed so that the patient can not see his / her legs. The curtain 110 is intended to increase the degree of immersion of the patient when treating the patient with pain. According to the present embodiment, the treatment of the pain in the knee patient is performed while the patient watches the motion image displayed on the monitor 230, which will be described later. In the absence of the curtain 110, This is because the effect of the treatment is reduced because the image and the actual foot of the user are forced to see the moving image. Therefore, the skin layer 110 should be made of an opaque material so that the patient can not directly see his / her legs. Here, the image displayed on the monitor 230 is a motion image obtained by mirror-inverting the normal joint motion image and the normal joint motion image. The motion image is provided instead of the motion image of the operated leg. This will be described in detail below.

The treatment unit 200 includes a camera 210, an image processing module 220, a monitor 230, and the like. This will be described in detail.

The camera 210 is positioned in front of the patient's leg and serves to photograph the patient's normal legs. Of course, it is a matter of course that the position of the camera 210 is adjusted according to the body shape and the sitting posture of the patient. Here, as shown in FIG. 1, the camera 210 is shown as one camera, but the present invention is not limited thereto. In other words, other media that can enhance the patient's own immersion level for pain treatment can be fully utilized by implementing the pain treatment of the patient as a three-dimensional image. For example, two or more cameras or stereo cameras may be used. In addition, a Depth sensor for measuring the depth of a space and a Motion Tracking sensor for tracking motion can be used. Through these configurations, a three-dimensional image can be implemented on the monitor 230. Of course, in order for the patient to view it three-dimensionally, the patient must wear the proper configuration, which will be described below.

The image processing module 220 performs a mirror inversion process on the normal joint motion image captured by the camera 210 and displays the image on the monitor 230 instead of the motion image of the operated leg. Hereinafter, the image of the normal joint motion captured by the camera 210 will be referred to as a 'first motion image,' and the image of mirror motion reversed normal joint motion will be referred to as a 'second motion image.' The second movement image is generated and displayed instead of the motion image of the operated leg, which causes confusion in the brain sensory cognitive function through the illusion phenomenon in which the patient perceives the second movement image as a part of the body of the user, .

The image processing module 220 will be described with reference to FIG.

Referring to FIG. 2, an image receiving unit 221 for receiving an image captured by the camera 210 is constructed.

And an image converting unit 222 for converting the first motion image received by the image receiving unit 221 into a second motion image in real time. That is, the image transforming unit 222 transforms the first motion image photographed by the camera 210 by mirror inversion processing into a second motion image by applying the principle of mirror therapy, And provides it to the monitor 230. At this time, the image converting unit 222 may also perform a function of removing various noise, etc., which may be included in the first motion image captured by the camera 210. This is to allow the patient to see a motion image with a clearer image quality.

An image transmitting unit 223 for transmitting the image-converted second motion image and the first motion image, which is the original image of the normal leg, to the monitor 230 so that the patient can directly view the image. That is, it provides symmetric images.

The reason why the first motion image photographed by the camera 210 and the second motion image obtained by mirror-reversing the first motion image are displayed as a horizontally symmetric image through the monitor 230 is that the brain sensation And the second exercise image is recognized as a motion image of the operated leg according to the function to perform the pain treatment.

The image processing module 220 may be a one-chip processor that performs the functions of the image receiving unit 221, the image converting unit 222, and the image transmitting unit 223, or may be a computer have. In the case of a one-chip processor, the image processing module 220 may be provided with a separate housing or the like to form an appearance. The image receiving unit 221 and the image transmitting unit 2230 of the image processing module 220 are connected to the camera 210 and the monitor 230 through a communication cable or a wireless communication medium. As a wireless communication medium, various communication methods such as wireless local area network (LAN), Bluetooth, and non-contact type short range wireless communication (NFC) may be applied.

The apparatus for treating pain of the present embodiment is a device for inducing an illusion that the patient's brain is exercising normally so that the therapeutic effect is obtained. In order to exhibit such a therapeutic effect, a long-term treatment period is required. Therefore, for continuous patient care and treatment, it is necessary to keep the image of joint motion and normal joint image for each individual patient.

The image processing module 220 further configures the image storage unit 224. The image storage unit 224 stores the patient's joint motion image and the normal joint image.

The image processing module 220 may further configure the image updating unit 225. The image updating unit 225 continuously updates the normal motion image corresponding to the surgical image for each treatment process of the patient in consideration of the surgical site that can be improved according to the patient's treatment process. This provides a normal motion image suitable for the treatment phase. The normal motion image to be updated is classified for each patient and stored in the image storage unit 224.

The normal motion image updated by the image updating unit 225 needs to be adjusted according to the degree of improvement of the patient's joint. That is, as the patient passes through the knee joint over time, the range of motion for the surgical site increases or becomes narrower. Therefore, it is necessary to reflect the change to allow the patient to perceive that the normal motion image reflects his / her improvement state and to perform the treatment. Accordingly, when the image updating unit 225 is configured in the pain treating apparatus, the image converting unit 222 performs a function of adjusting the motion range of the normal motion image according to the patient condition.

Referring again to FIG. 1, a monitor 230 is connected to the image processing module 220 to display an image on the screen. The monitor 230 is provided in front of the patient so that the patient can see the first motion image and the second motion image displayed while performing the rehabilitation motion. Preferably a position that can provide the same effect as a patient seeing a mirror and exercising.

When the monitor 230 supports three-dimensional images, that is, when the camera 210 includes two or more cameras or a stereo camera, or a depth sensor and a motion tracking sensor The monitor 230 is also displayed in three dimensions. Therefore, the patient can view the 3D image and increase the immersion degree. Of course, the patient must wear 3D glasses or binocular head mounted display (HMD) to see 3D images.

An embodiment of the present invention utilizes the principle of mirror healing and basically the patient should be able to recognize that the second motion image is his / her operated motion image. If the output of the second motion image is not recognized as an image of the patient's own joint motion image, the mirror treatment that causes the sensory cognitive function in the brain to be confused can not be effectively performed.

Therefore, the patient should be able to transmit an input message about whether or not the second motion image is directly recognized so that the second motion image output to the monitor 230 can be determined as the patient's own operation image. In this embodiment, the input button 112 is configured for this purpose. The input button 112 should be provided in a position where the patient can easily operate during treatment. For example, it may be provided on the upper surface of the curtain film 110. Of course, the input button 112 is merely an embodiment, and various other means such as a switch, a voice sensor, or the like capable of transmitting the input message may be employed.

The input signal according to the operation of the input button 112 is transmitted to the image processing module 220.

The image processing module 220 transmits another motion image to the monitor 230 according to whether the input button 112 is operated or not. First, when the input button 112 is not manipulated, it refers to a case where the patient does not recognize the second motion image as a part of his / her body, and at this time, the motion image of the operated leg is displayed on the screen. On the other hand, when the input button 112 is operated, it refers to a case where the patient recognizes the second motion image as part of the body, and at this time, the normal image converted from the second motion image is displayed on the screen.

Next, a process of treating a patient's pain during a rehabilitation exercise using the apparatus for treating a pain having the above-described configuration will be described. Referring to FIG. 3, which is a flow chart illustrating a process of performing a pain treatment of a patient according to driving of a pain treatment apparatus. Here, the flow chart of Fig. 3 refers to the first processing mode to be described later.

The patient who has undergone knee surgery seats in the chair for treatment (s100). In this state, the patient starts the leg exercise to move the leg around the knee for treating the pain (s101). At this time, the moving speed of the operated leg and the normal leg will be different. However, the patient does not see his / her leg movement by the skin 110.

When the patient himself or herself starts to move both legs, the camera 210 captures the motion of the normal leg (s102). The photographed motion image is a first motion image.

The image receiving unit 221 receives the first motion image and transmits it to the image converting unit 222 (s104). Then, the image transforming unit 222 performs mirror inversion processing on the first motion image in real time to generate the second motion image (s106). That is, the first motion image is converted into a motion image of the operated leg, that is, a second motion image, to apply the principle of mirror therapy. For example, when the right knee is operated, the motion information of the left knee is mirror-inverted and replaced with the motion image of the operated right knee. The image converting unit 222 displays the first motion image and the second motion image on the monitor 230 through the image transmitting unit 223 (s108).

Then, the patient can confirm the first motion image and the second motion image through the monitor (230). At this time, even though the patient can not follow the leg motion speed of the legs, the first motion image and the second motion image subjected to the mirror inversion process are symmetrically moved to the current monitor 230 Is displayed. Accordingly, the patient is subjected to an optical illusion which recognizes the leg motion displayed on the monitor 230 as his / her own leg motion. This is based on the principle of mirror therapy, in which the brain relies first on visual information. Therefore, the patient can rehabilitate while alleviating the pain (s110). Of course, when the position of the operated leg is different from that of the normal leg, the second processing mode of the image processing mode described later can be applied. The image processing mode will be described below.

During the rehabilitation treatment before the rehabilitation treatment, the patient may add a process of recognizing the second motion image as a part of his or her body.

As described above, the present embodiment is possible because the patient can not see his / her actual leg motion at all by the screen 110 and only the leg motion that is displayed on the monitor 230 can be confirmed. If the screen 110 is not provided, the patient can directly see the difference between the leg motion and the actual leg motion displayed on the monitor 230, and the effect of the rehabilitation treatment will be significantly lowered.

Patient immersion can be further increased through 3D imaging. As described above, providing the illusion phenomenon by the curtain 110 and the three-dimensional image together can provide an advantage of further increasing the therapeutic effect.

In the present embodiment, the camera 210 photographs the patient's legs directly to improve the immersion of the patient, and displays the images on the monitor 230 by mirror inversion. However, the present invention may provide the same effect without mirror inversion processing of the motion image taken by the camera 210. [ It is possible to use the normal motion image of the patient stored in the image storage unit 224. For example, when the camera 210 is not provided or the camera 210 is temporarily unavailable, the image processing module 220 refers to the patient's unique ID to display a normal motion image on the monitor 230 It is possible to do rehabilitation treatment through this.

As described above, one embodiment of the present invention is to treat the pain by confusing the cognitive function of the patient in the rehabilitation of the patient who operated on the unilateral disease such as the knee using the principle of mirror therapy.

Next, another configuration of the present invention will be described.

4A and 4B, which are illustrative block diagrams of an apparatus for treating pain for a bodily symmetric body disease according to a second embodiment of the present invention.

The apparatus for treating pain according to the second embodiment provides a structure in which the patient can perform all of the pain treatment at the seated seat. In the following description of the second embodiment, a description of a configuration that performs the same functions as those of the first embodiment will be omitted.

As shown in Figs. 4A and 4B, a chair 300 on which a patient is seated is provided.

The curtain 310 is provided on the chair 300. The curtain 310 is intended to prevent the patient from recognizing the movement of his or her actual legs during the treatment of the pain, thereby improving the therapeutic engagement. Therefore, the shielding film 310 should be made of an opaque material.

In the second embodiment, the treatment unit, that is, the camera 321, the image processing module (configuration 220 in FIG. 2), and the monitor 322 are configured in the screening film 310. That is, both the camera 321, the image processing module, and the monitor 322 are provided on the inside of the screening film 310 and on the upper and lower sides thereof. Here, the image processing module is the same as the configuration and the function described in the first embodiment, and is provided inside the screening film 310, so it is not shown in the drawings.

A camera 321 is mounted on the lower surface of the screening film 310. The camera 321 serves to photograph the movement of the leg when the patient moves the leg. At this time, though not shown in the drawing, a guide groove having a predetermined shape is formed on the lower side of the curling film 310, and a coupling protrusion formed at one end of the camera 321 is formed. Therefore, the engaging projection is movable along the guide groove in a state of being fitted in the guide groove. A configuration for adjusting the position of the camera 321 is provided. As described above, the camera can be moved in the forward / backward / left / right directions on the lower surface of the shielding film 310 by the structure of the guide groove and the coupling protrusion. This is because the patients who sit in the seats are all different body types.

In the second embodiment, the camera 321 can use a stereoscopic camera or two or more cameras to capture 3D images. As another example, a Depth sensor for measuring the depth of a space and a Motion Tracking sensor can be used.

A monitor 322 is formed above the screening film 310. The monitor 322 may be configured to be capable of adjusting the tilt angle so that an image displayed on the monitor 322 can be easily viewed while the patient is seated. An input button 311 is mounted on one side of the monitor 322. The position of the input button 311 can be changed.

An image processing module is provided in the shading film (310). The image processing module includes an image receiving unit, an image converting unit, and an image transmitting unit, which are described in the first embodiment. However, since the image processing module is constructed in the skin layer 310 as shown in FIG. 4, it is possible to describe the advantage that the entire space for installing the pain treatment apparatus can be smaller than the first embodiment.

The pain treatment process using the pain treatment apparatus provided by the second embodiment is as follows.

First, the patient who has undergone the knee surgery seats in the chair and adjusts the position of the camera 321. Since the camera 321 can move in the forward / backward / left / right directions on the lower surface of the screening film 310, the camera 321 can be adjusted in accordance with the body shape of the patient.

In this state, when the patient starts the leg exercise, the camera 321 photographs the motion image (i.e., the first motion image) of the legs of the legs of the patient. At this time, the leg motion is not only the shape of the normal leg but also the operated leg, but the movement of the normal leg and the operated leg is different from each other.

The image receiving unit of the image processing module receives the first motion image captured by the camera 321. The image receiving unit transmits the first motion image to the image converting unit.

The image converting unit newly generates a second motion image by real-time mirror inversion processing of the first motion image. Then, the motion image of the operated leg is replaced with the second motion image. The image transmitting unit transmits the first motion image and the second motion image to the monitor 322.

Then, the patient can confirm the first motion image and the second motion image through the monitor 322. [ At this time, the first motion image and the second motion image displayed on the monitor 322 appear at the same moving speed. That is, even if the patient is in a different position because the actual operated leg can not keep up with the normal leg motion speed, the first motion image and the mirror inversion processed second motion image are displayed on the current monitor 322 in a horizontally symmetrical state The patient is faced with an illusion phenomenon in which the leg motion displayed on the monitor is recognized as the actual leg motion.

 This can be expected to result in a higher therapeutic effect in relieving pain by disrupting the brain sensory cognitive function of the present invention.

Here, when the position of the operated leg is different from that of the normal leg as in the first embodiment, a second processing mode of the image processing mode described below can be applied, which will also be described below.

FIG. 5 is a view schematically showing an allowable range of a knee joint and a range of a normal knee joint applied to an embodiment of the present invention.

5, the operation joint 501 of the patient is operated according to the actual exercise capacity of the patient, and the minimum joint range 502 and the maximum joint joint range 502 503).

At this time, the available range 504 of the surgical joint from the minimum operative range 502 to the maximum operable range 503 is obtained.

Thus, the camera 210 (321) measures the available range 504 of the surgical joint, and calculates the normal availability range 508 of the surgical joint through the available range 504 of the surgical joint. At this time, the normal availability range 508 has a wider range than the surgical joint availability range 504, and the minimum allowable joint availability range 506 and the maximum normal joint availability range 507 are calculated, (508). The normal arthritic motion image for which the normal availability range 508 is determined is made visible to the patient through the monitors 230 and 322, and the treatment proceeds through this.

The patient's available range 504 of the joint is stored in the image storage unit 224 and stored in the image update unit 225 in accordance with the patient's available range 504 of the stored patient, Thereby adjusting the normal availability range 508 to enable the knee joint treatment to be performed.

6 is a flowchart showing the process of FIG.

As shown in FIG. 6, in order to perform the pain treatment, the available range of the joint joint 504 is measured with the joint motion image (s601).

Then, the normal availability range 508 of the surgical joint is calculated from the image of the surgical joint motion (s602). Thereafter, the patient can see the normal joint motion image that is moving in the normal availability range, and the patient is treated according to the process (S603).

Here, when the patient performs leg exercises, it is necessary to separate and secure exercise information of the operated legs and the normal legs. That is, it is for use in image processing by using motion information about the number of times of motion of the operated legs and the normal legs or the range of available joints. Accordingly, in the present embodiment, an inertial sensor module including an acceleration sensor and an angular velocity sensor may be attached to the patient's leg to sense leg movement. Preferably, the inertial sensor module is mounted on the ankle of the patient. This is because, when mounted on the ankle, it is possible to sense the leg motion more precisely than when the leg motion is mounted on another part.

The present invention supports two processing modes in performing image processing.

The first processing mode is a mode in which the first motion image, which is the motion image of the normal leg, and the second motion image obtained by mirror-inverting the first motion image, And is displayed in a symmetrical state in real time. The second movement image is the motion image of the operated leg.

The second processing mode is a mode in which the reversed motion image of the normal leg is displayed on the screen in consideration of the position of the operated leg rather than unconditionally displaying the image as shown in the first processing mode.

This will be described with reference to FIG.

The patient who has undergone knee surgery seats in a chair for treatment (s700).

In this state, the patient starts a leg exercise to move the leg around the knee to treat the pain (s701). At this time, the moving speed of the operated leg and the normal leg will be different.

When the patient starts to move both legs, the camera captures both leg movements and determines its position (s702).

If it is determined that the normal leg and the operated leg are opposite to each other (S704), for example, when the normal leg is directed to the front side and the operated leg is directed to the rear side, The image information of the normal leg located in the closest correspondence is accessed from the image storage unit and displayed on the screen (S706). For example, when the operated leg is located at about 15 degrees backward, the image processing module accesses image information in which the normal leg is located at a position of 10 to 20 degrees backward from the image stored in the image storing section, The image information is mirror-reversed and displayed on the screen together with the motion image of the current normal leg so that it can be recognized as a motion image of the normal leg.

If it is determined that the normal leg and the operated leg are located in the same direction, it is also possible to display a motion image obtained by mirror-inverting the normal leg and the normal leg without accessing the image storage unit. I.e., the first motion image and the second motion image (S708).

If the second treatment mode is supported, even if the operated limb is not moved well, the patient can be mistaken for the fact that the limb is moving well. Further, according to the position of the operated limb, The actual movement of the legs is completely different, so that it is possible to prevent the pain and the rehabilitation movement from being interrupted in advance.

And the first processing mode and the second processing mode described above are appropriately mixed and provided during leg exercise.

FIG. 8 shows a flowchart for performing two processing modes.

The two processing modes are performed depending on whether or not the input button 112 (311), i.e., the immersion button, mentioned in the above two embodiments is operated.

A patient who has undergone knee surgery is seated in a chair for treatment (s800).

Then, the image processing module determines whether the patient has operated the input button (s802).

As a result of the determination, if the input button is not operated, the image processing module processes the image information so that the first processing mode is performed (S804), and the patient performs the rehabilitation treatment using the first processing mode.

On the other hand, when the input button is operated, the image processing module processes the image information so that the second processing mode is performed (S806), and the patient performs the rehabilitation treatment using the second processing mode.

The first processing mode and the second processing mode performed according to whether or not the input button is operated will be omitted because they have been described above.

As described above, the present invention enables rehabilitation treatment using the first treatment mode or the second treatment mode depending on the patient's will.

The principles of the present invention, which is an external symmetrical apparatus for treating a physical disease, and a therapeutic process applicable to a patient will be described.

The embodiments of the present invention provide a pain treatment apparatus for a physical disease, which is an external symmetric body, using mirror reflection image processing. The patient recognizes the surgically treated joint motion image as a normal joint motion image and recognizes it as a part of the body of the patient , The sensory cognitive function of the brain is disrupted and the pain can be relieved.

In addition, as a treatment to reduce pain by giving priority to the recognition of motion control by disrupting the false sensory input caused by cutting, it can be used for the treatment of central pain, complex pain syndrome, fibromyalgia It has a pain relief effect.

Mirror therapy can be triggered by a biased sensory representation of the cerebrum that causes mismatch of motion and sensation, and normalization of the biased sensory representation of the cerebrum is associated with a reduction in pain. As a corrective measure, the effect of the mirror treatment is reported to induce the abnormal plasticity of the brain that occurs after the amputation or paralysis to be controlled by the mirror treatment, and the brain plasticity can be changed through acquired experiences. The sensory perception of cerebral cortex can be actively adapted according to the external environment, such as the fact that the artificial arm is attached to the existing arm and that the existing arm has become longer and the somatosensory evoked potential of the thumb has changed. To perform patient treatment. In addition, mirror therapy induces conflicts in the perception of the cerebrum to the movement and sensory signals transmitted from the body, induces uncertainty in the secondary input signal, and visually feedbacks the normal motion of the opposite side of the mirror, It may lead to plasticity of the brain responsible for the site. This is because the motor evoked potential is increased in a specific region of the brain through mirror therapy, the lateral readiness potential (LRP) increases in proportion to the similarity of the mirror image, and the F- And 'spinal motor neuronal excitability', which is similar to that of 'spinal motor neuronal excitability'.

In addition, the effect of mirror treatment is that the visual capture phenomenon, in which the visual takes precedence over the somatic sensation, and the error in the direction setting for capturing the object, It can affect sensory re-implementation. The mirror is activated by the rubber hand illusion phenomenon, which recognizes the rubber hand with the hand of the user, and the mirror nneuron system reported in the primates, when the external hand is used to provide external stimuli using the rubber hand and mirror It induces an embodiment of recognizing the specific requirements of the external object as the body of the person.

In addition, the learning effect on paralysis after hemiplegia is not a mirror treatment that induces a reduced awareness of the pain area, such as non-use of the non-use, which does not want to use the unconscious paralyzed arm, May be helpful, and the effect of inducing unconscious movements through cerebral activation of the obscured body part may be utilized.

According to a preferred embodiment of the present invention, a prospective, single-blind (assessor-blind), parallel group, randomized (allocation ratio 1: 1]), a single-cohort clinical study, quantitative verification of pain reduction after mirror-assisted virtual reality treatment with a mirror treatment, dose-dependent effects, and improvement of 'functional ends' Respectively.

In this regard, we performed the above - described procedure for the treatment of pain medication for physical illness symmetry for knee pain relief based on the patients who had undergone the above - mentioned Knee Replacement Surgery and who were transferred to the Rehabilitation Department. However, patients with visual impairment who are not able to see pain medication for physical illness symmetry, musculoskeletal or neurological disorders, patients with limited voluntary movement of the lower limb, and patients who can not understand VAS (Visual Analogue Scale) Verification was performed except for those patients whose scores could not be calculated.

In a preferred embodiment of the present invention, the pain treatment device for external symmetrical physical diseases is a randomized generator using 'a random assignment generator' which provides 'sequentially numbered containers' The patients were divided into full term intervention and half term intervention, and the patient group was transferred to the virtual reality therapist in the sealed envelope just before the adjustment. Gender, weight, height, and the first evaluation of the postoperative period were evaluated based on gender differences and gender differences in mirror vision.

In addition, the level of education and depressive emotions that may affect the experiment may be influenced by the depression index (Short Form Geriatric Depression Scale), VAS while resting and moving, (WOMAC index), graded ambulation distances, a 6-minute walk test, and a timed-stand test.

In a preferred embodiment of the present invention, a treatment method using a pain treatment apparatus for a physical disease, which is symmetrical, is a goniometer in which a knee is flexed spontaneously in a state in which a patient is lying in a mid- The fulcrum is fixed to the lateral support point with the fulcrum facing the greater trochanter and the remaining arm is fixed to the lateral calf bone with the lateral malleolus facing. Place the 4-inch roll under the ankle while lying on the temple, and measure the range to 0 ° in the same way as bending using a goniometer. The therapist will provide treatment according to the patient group in the sealed envelope, and all groups will be provided with standardized physical therapy for two weeks, and the entire treatment group will receive the virtual reality for five weeks and two weeks, once a day after the end of physical therapy. The treatment is proceeded according to. In addition, the partial-period treatment group can provide the virtual reality such as the standard 1 physical therapy in the first half and the treatment group in the last one week. The virtual reality is a somatotopic principle for the body-specific region, so that all the limbs to be treated can be seen, and the intermanual transfer is not triggered by the mirror treatment, Considering that the movement reflects strengthening the brain plasticity, it is set to move the knee at the same time to construct the virtual reality. In the virtual reality, the therapist adjusts the height of the chair so that the sole of the patient is positioned at 10 cm above the ground, then the hip and knee are at 90 °, the waist is perpendicular to the ground, After fixing the fuselage and thighs, position the camera in front of the patient and adjust the distance so that both legs and perineals on both sides of the screen are photographed and the joints of both lower legs are reconstructed naturally. Close the desk firmly, and hold the handle on the desk with both hands. Thereafter, the patient is allowed to freely move for 5 minutes in the range of the available joint joints while watching the screen, and the validity of the virtual reality is evaluated. After one minute of rest, the virtual reality is shown and the legs are flexed and relaxed 50 times at the same time.

Also, after the above virtual reality treatment, 1st session (1 week). At the 2nd session (2 weeks), the physical activity or virtual reality was terminated immediately after the completion of R1, and the VAS with at resting and moving, total ROM of flexion and extension, WOMAC index, graded ambulation distances, After 6 weeks, R1 was assessed with VAS at resting and moving, total ROM of flexion and extension, WOMAC index, graded ambulation distances, 6 minute walk test, and timed-stand test parameters, the results of the apparatus and the control method for the knee pain using the virtual reality were verified.

As described above, the present embodiment improves the patient's immersion level by applying the principle of mirror therapy as a pain treatment apparatus except for the palliative treatment such as drugs and the like, thereby preventing confusion in the cognitive function of the patient after the operation for the unilateral disease such as the knee joint To provide a technical point that a pain treatment device for a physical symmetric body disease is constructed to treat the pain.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, It will be apparent that modifications, variations and equivalents of other embodiments are possible. Therefore, the true scope of the present invention should be determined by the technical idea of the appended claims.
