Description

[Technical Field]

[0001] The present invention relates to a patient condition stabilization device and a patient condition stabilization program, and is particularly suitable for use in a device and program that assists in stabilizing the brain state of a patient. [Background technology]

[0002] In contrast to transient pain caused by illness or injury, there is chronic pain, which lasts for a long time. Chronic pain is caused by damage to the nervous system and is known to be amplified by psychological factors (mental and psychological issues such as stress and anxiety). Even in patients where some physical factor (e.g., brain or spinal cord disease or injury) is clearly involved in the persistence of chronic pain, psychological factors are often also involved. If chronic pain is left untreated, it can be physically and mentally exhausting, resulting in symptoms such as insomnia, loss of appetite, impaired concentration, and irritability. The stress caused by chronic pain can lead to depression, which can interfere with social life.

[0003] Traditionally, various drugs and psychological treatments have been used to treat chronic pain. Recently, applications that support the treatment of chronic pain (so-called therapeutic apps) have also been provided (see, for example, Non-Patent Document 1). The therapeutic app described in Non-Patent Document 1 aims to improve chronic pain mainly by performing brain retraining exercises.

[0004] It is expected that retraining the brain will bring it closer to a normal state, thereby improving chronic pain. However, if the patient is in a mentally unstable state, the brain will not be in a state where it can accept retraining. Therefore, before using a therapeutic app to retrain the brain, it is necessary to stabilize the patient's mental state by stabilizing the brain's state and preparing the patient's mind to accept the training.

[0005] There are known techniques for diagnosing brain diseases or neurological diseases in subjects by analyzing biometric information, such as electroencephalograms, obtained when the subject performs content (see, for example, Patent Documents 1 to 3). Patent Documents 1 and 2 disclose the use of physiological indices relating to the subject's level of relaxation, stress, enjoyment, and increased motivation when performing content. Patent Document 3 discloses the use of biometric information obtained when a patient and a healthy person perform the same content, in addition to the subject's biometric information, to determine whether the subject has a disease or not.

[0006] However, the technologies described in Patent Documents 1 to 3 diagnose whether a subject is suffering from a brain disease or a neurological disease based on biometric information obtained when the subject performs content, and do not provide any mechanism for stabilizing the state of the brain.

[0007] Similar problems exist not only in patients with chronic pain but also in patients with neurological disorders such as dementia and autism. Brain training applications (known as brain training apps) are used as a means of preventing or slowing the progression of neurological disorders. Brain training primarily aims to prevent or restore decline in cognitive function (memory, language comprehension, attention, perception, reasoning, etc.). Even when neurological patients use these types of brain training apps, it is desirable to stabilize the brain's state and prepare the mind to accept the training beforehand in order to maximize the effectiveness of brain training.

[0008] Brain training apps that allow family members to train together are also available (see, for example, Non-Patent Document 2). The brain training app described in Non-Patent Document 2 is designed to prevent dementia by combining it with a "family site (website)" that allows family members to share the app's activities and brain status, allowing the whole family to safely and enjoyably engage in brain health maintenance activities. However, this brain training app is designed to prevent dementia by allowing healthy individuals to compete in brain training against each other, and is not intended to improve the mental stability of patients with neurological disorders and thereby increase their positive motivation for treatment.

[0011] The present invention has been made in view of the above circumstances, and has as its object to provide an application having a mechanism for stabilizing the state of the brain. [Means for solving the problem]

[0012] In order to solve the above-mentioned problems, in the present invention, when a patient with a brain disease, neurological disease, or psychiatric disease and a healthy person who has a close relationship with the patient perform a task together, biometric information generated is obtained from both the patient and the healthy person, and the stability of the patient's brain state is evaluated from the perspective of whether the patient's biometric information and the healthy person's biometric information are synchronized or synchronous. [Effects of the Invention]

[0013] According to the present invention configured as described above, when a patient jointly experiences a task with a healthy person and the patient empathizes with the healthy person, the biological information generated by the healthy person and the biological information generated by the patient become synchronized or entrained. By utilizing this property, the stability of the patient's brain state can be evaluated based on whether the biological information generated by the healthy person, whose brain state is stable, is entrained or entrained with the biological information generated by the patient empathizing with the healthy person. Based on the evaluation results, the patient and the healthy person can repeatedly engage in a joint experience while changing the task as appropriate, thereby further stabilizing the patient's brain state. By jointly experiencing the task with a healthy person who has a close relationship with the patient, rather than the patient performing the task alone, the patient is more likely to continue the repeated joint experience for a long period of time and be more likely to empathize.

DETAILED DESCRIPTION OF THE INVENTION

[0015] An embodiment of the present invention will be described below with reference to the drawings. Fig. 1 is a diagram showing an example of the overall configuration of a healthcare system using a biological condition stabilization support device according to this embodiment. The healthcare system of this embodiment is configured to include a biological information detection sensor 101 worn by a patient PT suffering from a brain disease, a neurological disease, or a mental disease, a biological information detection sensor 102 worn by a healthy person HP who has a close relationship with the patient PT, and a biological condition stabilization support device 10. In this embodiment, the patient PT includes not only those who have actually been diagnosed with a disease, but also those who are suspected of having a disease.

[0016] The biological information detection sensors 101 and 102 are sensors for detecting biological information. The biological information detected by the biological information detection sensors 101 and 102 is, for example, one or a combination of two or more of brain waves, heartbeat, cardiac potential, pulse wave, respiration, blood pressure, blood flow, myoelectric potential, sweating, blinking, eye movement, body movement, and body position. The biological information detection sensors 101 and 102 are provided in a wearable terminal equipped with wireless communication means such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). The wearable terminal wirelessly transmits the biological information detected by the biological information detection sensors 101 and 102 to the biological condition stabilization assistance device 10.

[0017] The biological condition stabilization support device 10 is configured by, for example, a smartphone, tablet, or personal computer equipped with wireless communication means such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). The biological condition stabilization support device 10 receives and records the biological information of the patient PT and the biological information of the healthy subject HP wirelessly transmitted from the biological information detection sensors 101, 102, and evaluates the stability of the patient PT's brain based on this biological information.

[0018] The biological condition stabilization support device 10 of this embodiment is designed to evaluate the stability of the brain state of the patient PT and stabilize the brain state by utilizing the empathy that occurs when the patient PT and a healthy person HP who has a close relationship with the patient PT jointly experience a task. The healthy person HP who has a close relationship with the patient PT is, for example, a family member, close relative, friend, or medical professional who has a certain relationship with the patient PT, such as a family doctor.

[0019] The tasks that are shared are primarily intended to stimulate emotions and feelings, and examples include the following: Music: Listening to music, playing music, keeping rhythm, etc. Physical activity: Yoga, breathing, moving the body, etc. Smell: Smelling aromas, tasting sake, etc. ·Video···Looking at photos, watching movies, etc. Clothing: Dressing up, wearing clothes, coordinating colors, etc. Art: Drawing, mixing colors, combining shapes and blocks, etc. Other: Cooking and eating, playing with animals, playing games, reading, etc.

[0020] As described above, the biological condition stabilization support device 10 of this embodiment aims to stabilize the brain state of the patient PT by utilizing empathy when the patient PT and the healthy individual HP jointly experience a task. Therefore, when the patient PT empathizes with the healthy individual HP during a joint experience, it is desirable that the healthy individual HP himself / herself be in a state of engaging in the joint experience in a positive and enjoyable manner. Therefore, it is preferable that the task jointly experienced by the patient PT and the healthy individual HP is, for example, one that the healthy individual HP is interested in. It is also desirable that the task to be jointly experienced is one that the patient PT himself / herself can engage in in a positive and enjoyable manner. Therefore, it is more preferable to select a task that both the healthy individual HP and the patient PT are interested in and carry out the joint experience.

[0021] The joint experience between the patient PT and the able-bodied HP is repeatedly carried out, with the content or implementation method of the task being changed as appropriate. Each time a joint experience is carried out, the biological information generated in the patient PT and the able-bodied HP at that time is detected by the biological information detection sensors 101, 102, respectively. Changing the content of the task includes, for example, changing the task from "listening to music" to "playing music" within the same "music" category, or changing a "music" task to a different "video" category. Changing the content of the task also includes, for example, changing the music (content) to be listened to without changing the task of "listening to music." Changing the method of performing the task, on the other hand, includes, for example, changing the playback volume, changing the listening location, or changing the able-bodied HP listening together, without changing either the task of "listening to music" or the music (content) to be listened to.

[0022] In this way, the content and methods of the tasks that patient PTs experience together with healthy HPs are diverse, rather than being uniform like traditional brain training apps. By implementing tasks that are not uniform, it is possible to increase the rate at which patient PTs complete and continue the tasks. Furthermore, by increasing the rate of contact with family members and close relatives who participate in the shared experience and reducing the psychological distance, it is possible to effectively stabilize the brain, nerves, and mind of patient PTs.

[0023] Fig. 2 is a block diagram showing an example of the functional configuration of the biological condition stabilization support device 10 according to this embodiment. As shown in Fig. 2, the biological condition stabilization support device 10 of this embodiment includes, as functional components, a biological information acquisition unit 11, a stability evaluation unit 12, and an information provision unit 13. The biological condition stabilization support device 10 also includes, as storage media, a biological information storage unit 21 and an evaluation result storage unit 22.

[0024] The functional blocks 11 to 13 can be configured by any of hardware, DSP (Digital Signal Processor), and software. For example, when configured by software, the functional blocks 11 to 13 are actually configured with a processor such as a CPU or GPU of a computer, RAM, ROM, etc., and are realized by running a biological condition stabilization support program stored in a storage medium such as RAM, ROM, a hard disk, or a semiconductor memory.

[0025] The biometric information acquisition unit 11 acquires biometric information from each of the patient PT and the able-bodied person HP that is generated when the patient PT and the able-bodied person HP jointly perform a task. As described above, the joint experience between the patient PT and the able-bodied person HP is repeatedly carried out while appropriately changing the content or method of the task. Each time a joint experience is carried out, the biometric information acquisition unit 11 acquires the biometric information of the patient PT and the able-bodied person HP detected by the biometric information detection sensors 101, 102 from the wearable terminal. The acquired biometric information is then sequentially stored in the biometric information storage unit 21.

[0026] The stability evaluation unit 12 evaluates the stability of the patient's brain state from the perspective of whether the biometric information of the patient PT and the biometric information of the healthy subject HP acquired by the biometric information acquisition unit 11 are synchronized or synchronous, and stores the evaluation results in the evaluation result memory unit 22.

[0027] For example, when electroencephalograms are used as biometric information, the stability evaluation unit 12 calculates the similarity between the electroencephalograms of the patient PT and the healthy subject HP, and determines that the biometric information is synchronized or entrained if the similarity is equal to or greater than a threshold. The similarity with electroencephalograms here refers to the similarity regarding one or a combination of two or more of waveform, wavelength, period, etc. The same applies when cardiac potential, pulse wave, blood flow, myoelectric potential, etc. are used as biometric information.

[0028] Furthermore, when heartbeat is used as the biological information, the stability evaluation unit 12 calculates the similarity between the heartbeat of the patient PT and the heartbeat of the healthy subject HP in terms of heart rate, timing of heartbeats, etc., and determines that the biological information is synchronized or entrained when the similarity is equal to or greater than a threshold. Similarly, when respiration is used as the biological information, the stability evaluation unit 12 calculates the similarity between the respiration of the patient PT and the respiration of the healthy subject HP in terms of the number of breaths per unit time, timing of breathing, etc., and determines that the biological information is synchronized or entrained when the similarity is equal to or greater than a threshold.

[0029] The similarity can be calculated using known index values, such as a correlation coefficient, a cosine similarity based on a feature vector extracted from biometric information, a Euclidean distance, or a Mahalanobis distance.

[0030] The information providing unit 13 provides the evaluation result to the user by displaying information indicating the evaluation result of the stability evaluation unit 12 on a display. For example, the information providing unit 13 displays on a display the determination result of whether or not the biological information of the patient PT and the biological information of the healthy subject HP are synchronized or synchronous (information indicating whether or not the similarity is equal to or greater than a threshold). The information providing unit 13 may also provide information indicating the degree of similarity between the biological information of the patient PT and the biological information of the healthy subject HP. The information providing unit 13 may also display on a display the biological information of the patient PT and the biological information of the healthy subject HP (corresponding to the evaluation result) stored in the biological information storage unit 21, together with information indicating the evaluation result.

[0031] The healthy individual HP, upon viewing the information provided by the information providing unit 13, can decide whether to continue the joint experience, whether to consult with a medical professional (such as a neurological disease specialist) other than the person implementing the joint experience, whether to start using a treatment app or a brain training app, etc. The healthy individual HP can also share the information provided by the information providing unit 13 with a medical professional as a pre-medical interview and discuss the timing of medical examinations and treatment interventions.

[0032] Furthermore, when a patient with no awareness of their illness, such as a neurological disease like chronic pain, dementia, or autism, is participating in a shared experience of a task, the information provided by the information provider 13 can be conveyed to the patient to help them gain correct awareness of their illness and encourage them to begin treatment with a specialist or start using a treatment app or brain training app without any difficulty. This has the advantage of lowering the hurdles associated with initial consultations and treatment interventions, thereby reducing the burden on family and relatives who monitor and care for the patient. Furthermore, it is possible to share the content of the shared experience and the evaluation results conducted before treatment began with medical professionals who have begun treatment, which is expected to improve the accuracy of treatment.

[0033] As described above, according to this embodiment, when a patient PT jointly experiences a task with a healthy subject HP and the patient PT empathizes with the healthy subject HP, the biological information generated by the healthy subject HP and the biological information generated by the patient PT become synchronized or synchronized. By utilizing this property, the stability of the patient PT's brain state can be evaluated based on whether the biological information generated by the healthy subject HP, whose brain state is stable, is synchronized or synchronized with the biological information generated by the patient PT who empathizes with the healthy subject HP. Based on this evaluation result, the patient PT and the healthy subject HP can repeatedly engage in a joint experience while changing the task as appropriate, thereby making the patient PT's brain state more stable. By jointly experiencing a task with a healthy subject HP with whom the patient PT has a close relationship, rather than having the patient PT perform the task alone, the patient PT is more likely to continue the repeated joint experience for a long period of time and to be in a state where empathy can be easily achieved.

[0034] The information providing unit 13 may output a message urging a change in the content or implementation method of the task based on the evaluation results by the stability evaluation unit 12. For example, the information providing unit 13 analyzes each result (multiple evaluation results stored in the evaluation result storage unit 22) evaluated by the stability evaluation unit 12 based on the biological information when the same task is repeatedly performed in the same method, and outputs a message urging a change in the content or implementation method of the task if it is determined that the biological information of the healthy subject HP and the biological information of the patient PT are not synchronized or entrained for a predetermined number of consecutive times or more.

[0035] Alternatively, the information providing unit 13 may analyze the results of each evaluation by the stability evaluation unit 12 based on the biological information when tasks of the same type are repeatedly performed (multiple evaluation results stored in the evaluation result storage unit 22), and if it is determined that the biological information of the healthy subject HP and the biological information of the patient PT are not synchronized or in sync for a predetermined number of consecutive times or more, output a message urging the user to change to a task of a different type. Tasks of the same type refer to tasks of the same category, such as tasks related to music or tasks related to body movement.

[0036] The information providing unit 13 may analyze the evaluation results when the same task is repeatedly performed in the same way, and if a gradual increase in the similarity of the biometric information is observed, output a message encouraging the subject to continue performing the same task in the same way. Similarly, the information providing unit 13 may analyze the evaluation results when the same type of task is repeatedly performed, and if a gradual increase in the similarity of the biometric information is observed, output a message encouraging the subject to continue performing the same type of task.

[0037] Furthermore, the information providing unit 13 may further output suggested information on changes to the content or implementation method of the task based on the evaluation results by the stability evaluation unit 12. For example, information on the content and implementation method of the performed task may be stored in the evaluation result storage unit 22 along with information on the evaluation results by the stability evaluation unit 12. The information providing unit 13 then analyzes the results of the evaluations performed by the stability evaluation unit 12 based on the bioinformation obtained when the same task is repeatedly performed in the same method, and if it has been determined that the bioinformation of the healthy subject HP and the bioinformation of the patient PT are not synchronized or entrained for a predetermined number of consecutive times, outputs suggested information on changes to a task with content different from that stored in the evaluation result storage unit 22 or an implementation method different from that stored in the evaluation result storage unit 22.

[0038] Alternatively, the information providing unit 13 may analyze the evaluation results of each task when the same type of task is repeatedly performed, and if it is determined that the biometric information of the healthy subject HP and the biometric information of the patient PT are not synchronized or synchronous for a predetermined number of consecutive times or more, it may output a task of a different type from the task stored in the evaluation result storage unit 22 as suggested information for changes.

[0039] Furthermore, as shown in FIG. 3 as an example of the functional configuration of the biological condition stabilization support device 10A according to the first modified example, the biological condition stabilization support device 10A may further include a second information providing unit 14 that outputs a message encouraging intervention by a medical professional other than the person performing the task (e.g., a specialist in neurological diseases) or transition to the next stage of treatment (e.g., treatment by a specialist, use of a treatment app or a brain training app, etc.) based on the evaluation results by the stability evaluation unit 12.

[0040] As an example, the second information providing unit 14 outputs a message urging a medical professional to intervene or to move to the next stage of treatment when the stability evaluation unit 12 determines that the biological information of the healthy subject HP and the biological information of the patient PT are synchronized or in sync. Alternatively, the second information providing unit 14 may analyze multiple evaluation results stored in the evaluation result storage unit 22, and output a message urging a medical professional to intervene or to move to the next stage of treatment when it is determined that the biological information of the healthy subject HP and the biological information of the patient PT are in sync or in sync a predetermined number of times or more.

[0041] As shown in FIG. 4 as an example of the functional configuration of the biological condition stabilization support device 10B according to the second modification, the biological condition stabilization support device 10B may further include a content selection unit 15 and a content storage unit 23. The content storage unit 23 stores information indicating content to be used in a task that the patient PT and the healthy individual HP jointly experience, in association with information indicating the task. The information indicating the content includes, for example, the type and name of the content, and various properties in the case of digital content (title, creation date and time, type, creation location information, genre, creator, comments, etc.). The content storage unit 23 may be included in a server device that can be accessed from the biological condition stabilization support device 10B via a communication network such as the Internet.

[0042] The content selection unit 15 selects content to be used for tasks in which the able-bodied person HP is interested or content in which the able-bodied person HP is interested from the content stored in the content storage unit 23, and displays the results on a display to present to the able-bodied person HP.

[0043] For example, the content selection unit 15 inputs information indicating a subject in which the able-bodied person HP is interested, and searches the content storage unit 23 for information on content stored in association with the input subject, and presents it. If there is a plurality of pieces of relevant content information, they may be displayed as a list, or any one selected according to a predetermined rule may be displayed. Here, the information indicating a subject in which the able-bodied person HP is interested is input by the able-bodied person HP using an input device such as a touch panel or keyboard, for example.

[0044] Alternatively, the content selection unit 15 may analyze the category of matters in which the healthy subject HP is interested by using browsing history information when the healthy subject HP browses websites using the web browser function of the biological condition stabilization support device 10B, and may search the content storage unit 23 using information indicating tasks in a system corresponding to that category as input information, thereby extracting and presenting information on content stored in association with the tasks from the content storage unit 23. Here, when one system includes multiple tasks, the content selection unit 15 searches the content storage unit 23 using any one or more of them as input information.

[0045] Here, an example is shown in which website browsing history information is used to analyze the categories of topics that healthy individuals are interested in, but analysis may also be performed using information other than browsing history information (for example, product purchase history on an e-commerce site, property information for digital content such as music and video stored in the biological condition stabilization support device 10B, etc.).

[0046] Furthermore, the content selection unit 15 may search for information indicating content stored in the content storage unit 23 (such as the type and name of the content, and various properties in the case of digital content) based on keywords input by the able-bodied person HP using an input device, and extract and present information on content that matches the keywords from the content storage unit 23. The keywords input here are keywords related to the interests of the able-bodied person HP. In this case, it is also possible to perform a keyword search for information on highly emotional content that the able-bodied person HP has frequently come into contact with and that holds strong memories for.

[0047] In addition, the content selection unit 15 may select content to be used for tasks that interest both the healthy individual HP and the patient PT, or content that interest both the healthy individual HP and the patient PT, from the content stored in the content storage unit 23, and display the results on a display to present to the healthy individual HP.

[0048] Furthermore, in Fig. 4, the second information providing unit 14 shown in Fig. 3 may be further provided. That is, the first modified example and the second modified example may be applied in combination.

[0049] As shown in FIG. 5 as an example of the functional configuration of the biological condition stabilization support device 10C according to the third modification, the biological condition stabilization support device 10C may further include a task selection unit 16 and a task storage unit 24. The task storage unit 24 stores information indicating tasks to be jointly experienced by the patient PT and the healthy individual HP. The information indicating the tasks may be, for example, the type and name of the task, keywords indicating the content of the task, or free text information. The task storage unit 24 may be included in a server device that can be accessed from the biological condition stabilization support device 10C via a communication network such as the Internet.

[0050] The task selection unit 16 selects a task that the able-bodied person HP is interested in from the tasks stored in the task storage unit 24, and presents the results to the able-bodied person HP on a display.

[0051] For example, the task selection unit 16 searches for information indicating tasks stored in the task storage unit 24 based on keywords input by the healthy individual HP using an input device, and extracts and presents task information that matches the keywords from the task storage unit 24. The keywords input here are keywords related to the interests of the healthy individual HP.

[0052] Alternatively, the task selection unit 16 may use information on the website browsing history of the healthy individual's HP to analyze the category of matters in which the healthy individual's HP is interested, and extract and present information indicating tasks in the system corresponding to that category from the task storage unit 24. Here, if one system contains multiple tasks, the task selection unit 16 extracts one or more of them.

[0053] In addition, the task selection unit 16 may select tasks that are of interest to both the healthy individual HP and the patient PT from the content stored in the task memory unit 24, and present the results to the healthy individual HP by displaying them on a display.

[0054] 5 may further include the second information providing unit 14 shown in FIG. 3. That is, the first modified example and the third modified example may be applied in combination. Also, FIG. 5 may further include the content selecting unit 15 and the content storage unit 23 shown in FIG. 4. That is, the second modified example and the third modified example may be applied in combination. Also, the first modified example, the second modified example, and the third modified example may all be applied in combination.

[0055] In the above embodiment, in addition to the evaluation results by the stability evaluation unit 12, the findings of the healthy subject HP who jointly performed the task (for example, information evaluating the emotional expression of the patient PT on a predetermined scale) may be stored in the evaluation result storage unit 22. In addition to this, behavioral information of the patient PT (for example, sleeping hours on the day the task was performed, time spent outside, etc.) may be stored in the evaluation result storage unit 22. In this way, not only the evaluation results but also the findings of the healthy subject HP and behavioral information of the patient PT can be shared with medical professionals, thereby improving the accuracy of diagnosis and treatment.

[0056] In addition, based on at least one of the history of biometric information stored in the biometric information storage unit 21 and the history of evaluation results stored in the evaluation result storage unit 22, it is possible to analyze trends in changes over time and predict changes in the patient's condition.

[0057] Furthermore, the threshold value used by the stability evaluation unit 12 to determine the similarity between the biological information of the patient PT and the biological information of the healthy subject HP may be set to a value according to the case and severity.

[0058] Furthermore, in the above-described embodiment, a task execution unit that executes tasks related to music, video, art, and other subjects may be provided in the biological condition stabilization support devices 10, 10A, 10B, and 10C.

[0059] Furthermore, the above-described embodiments are merely examples of specific embodiments for carrying out the present invention, and the technical scope of the present invention should not be construed as being limited thereby. In other words, the present invention can be carried out in various forms without departing from the gist or main characteristics thereof. [Explanation of symbols]
