Background Technology

[0003] Currently, as the average life expectancy of the Korean people continues to extend, population aging is progressing rapidly, and consequently, the dementia population is also continuously increasing.

[0004] Dementia is an incurable, progressive disease, making prevention extremely important. This is because early prevention before the onset of dementia can slow its progression, and in some cases, recovery is possible.

[0005] Computerized cognitive rehabilitation programs are software therapeutic tools that enhance and improve cognitive function by consistently and continuously repetitively training cognitive domains that have been particularly diminished due to cognitive impairment. The reason for the low utilization of such computer software-based cognitive rehabilitation programs is the lack of scientific and technical programs specifically designed for cognitive concentration training, which are based on literature evidence.

[0006] In addition, currently, in order to receive cognitive rehabilitation training and a dementia diagnosis, a primary cognitive function test must be performed at a public health center or hospital. Since these cognitive function tests are conducted one-on-one by an occupational therapist with the patient, there are issues such as increased workload, longer testing times, and wasted resources due to the production of screening test sheets.

[0032] FIG. 1 is a configuration diagram of a cognitive rehabilitation training system through user-customized content recommendation based on cognitive function test data according to one embodiment of the present invention, FIG. 2 is a perspective view of a cognitive rehabilitation chair included in a cognitive rehabilitation training system through user-customized content recommendation based on cognitive function test data according to one embodiment of the present invention, and FIG. 3 is a diagram showing the movement of each part of the cognitive rehabilitation chair.

[0033] A cognitive rehabilitation training system and method based on user-customized content recommendation using cognitive function test data according to one embodiment of the present invention is characterized by administering a computerized cognitive function test kit and automatically performing cognitive rehabilitation training tailored to the user's cognitive function by linking with a dedicated cognitive rehabilitation chair.

[0034] Referring to FIG. 1, the cognitive rehabilitation training system (10) according to the present embodiment includes a cognitive function test module (110), a cognitive rehabilitation content recommendation module (120), a cognitive rehabilitation management module (130), and a cognitive rehabilitation dedicated chair (140).

[0035] The cognitive function test module (110) tests the cognitive function of the user (subject) using a computerized cognitive function test kit and generates the results as computerized test data.

[0036] Here, the cognitive function test kit may be, for example, the MMSE-K (Mini Mental State Examination - Korea) kit, a screening tool developed to simply evaluate the subject's cognitive function and whether they have dementia within a short period of time.

[0037] A chair (140) dedicated to cognitive rehabilitation may include a chair section (141) on which a subject can sit and a monitor section (146) for outputting content related to cognitive function tests and / or cognitive rehabilitation training.

[0038] The chair part (141) may include a headrest (142) on which the subject's head rests and an armrest (143) on which the subject rests their arms.

[0039] And the chair part (141) can be installed so as to be movable in all directions (front, back, left, right) and up and down on a stage (144) having a predetermined height. In this case, a guide rail structure for movement in all directions and a cylinder structure for movement up and down can be applied in combination between the stage (144) and the chair part (141). A driving unit (e.g., a motor) for moving the chair part (141) can be installed within the stage (144). Accordingly, the chair part (141) can slide in all directions or move up and down on the stage (144) (②).

[0040] The backrest of the chair part (141) is hinged to the seat plate so that it can be hinged backward by a predetermined angle relative to the seat plate (①). The headrest (142) is hinged to the top of the backrest so that it can be hinged forward and backward by a predetermined angle relative to the backrest (④).

[0041] The armrest (143) is implemented with a tilting structure so that it can be tilted backward or upright (⑤). When a subject enters to sit in the chair section (141) or exits the chair section (141) after the examination or training is finished, the armrest (143) can be tilted backward to minimize interference during entry and exit.

[0042] These movements or hinge rotations of each part of the chair (141) are intended to provide the subject with an optimal sitting position so that cognitive function tests and / or cognitive rehabilitation training can be performed properly.

[0043] The monitor unit (146) can be connected to the main body unit (145) installed on the side of the stage (144) via a multi-joint arm unit (147). The multi-joint arm unit (147) includes a plurality of arms connected by joints capable of multi-degree-of-freedom movement, and the position of the monitor unit (146) can be freely adjusted in three-dimensional space.

[0044] Additionally, the end of the multi-joint arm (147) and the monitor (146) are hinge-connected so that the monitor (146) can be positioned to face any direction among front, back, up, down, left, and right at any point in three-dimensional space.

[0045] The main body (145) is electrically or communically connected to the monitor (146), and the execution screen of the computerized cognitive function test kit (test content) or the execution screen of the cognitive rehabilitation training content according to the present embodiment can be visually displayed through the monitor (146).

[0046] Additionally, a speaker may be installed in the headrest (142) or the monitor (146) to audibly output an audio signal to a subject seated in the chair (141) in response to the execution of test content and / or training content.

[0047] Additionally, a user recognition unit may be installed in the monitor unit (146). The user recognition unit may include a camera that captures the face of a subject seated in the chair unit (141). The subject's face may be analyzed from the image captured by the camera, and a facial recognition algorithm may be applied to enable automatic login if the subject is a previously registered user.

[0048] Additionally, if the subject's face is not in a designated position in the image captured by the camera, the user recognition unit transmits a control signal to the chair unit (141) so that the subject can receive examination or training in an optimal posture, thereby causing each component of the chair unit (141) to be actuated, so that the subject's posture is corrected and the subject can look straight at the monitor unit (146).

[0049] The cognitive rehabilitation content recommendation module (120) recommends cognitive rehabilitation content suitable for the current cognitive function of the subject based on the cognitive function test data performed by the cognitive function test module (110) and enables the performance of such content.

[0050] The cognitive rehabilitation management module (130) analyzes the evaluation results based on the performance of cognitive rehabilitation content and manages the rehabilitation history of the subject.

[0051] Referring again to FIG. 1, the cognitive rehabilitation content recommendation module (120) may include a customized rehabilitation content recommendation unit (121), a cognitive rehabilitation training performance unit (123), a cognitive function re-examination unit (125), and a content change matching recommendation unit (127).

[0052] The cognitive rehabilitation management module (130) may include an evaluation result analysis unit (131) and a rehabilitation history management unit (133).

[0053] The customized rehabilitation content recommendation unit (121) receives cognitive function test data from the cognitive function test module (110), analyzes it using artificial intelligence (AI), and recommends optimal customized cognitive rehabilitation content that can strengthen areas that are relatively weak for the subject. For example, if the orientation score is low, it recommends content to strengthen orientation, and if the language function score is low, it recommends content to strengthen language function.

[0054] In this case, content recommendations can be made by cross-validating the results of cognitive function tests with the results of content evaluations using machine learning. For example, if the cognitive function test result is mild and the content evaluation result is also mild, mild content can be recommended.

[0055] The cognitive rehabilitation training execution unit (123) executes the cognitive rehabilitation content recommended by the customized rehabilitation content recommendation unit (121), enabling the subject seated in the chair unit (141) to perform cognitive rehabilitation training.

[0056] In this case, the rehabilitation content is visually output through the monitor unit (146) and can be audibly output through the speaker as needed.

[0057] Here, a microphone is installed in the monitor section (146) or chair section (141) (especially the headrest (142)) of the cognitive rehabilitation chair (140) so that voice responses can be received during the process of the subject performing cognitive rehabilitation training.

[0058] Additionally, an eye-tracker may be installed in the monitor unit (146) as a user input unit. In this case, for a user who has difficulty using a computer, by tracking their gaze, they can select the answer corresponding to the option displayed on the screen of the monitor unit (146) through eye tracking.

[0059] This allows a subject seated in the chair (141) to effectively perform cognitive rehabilitation training by looking at the monitor (146) and performing simple eye movements and / or voice responses.

[0060] Additionally, during the process of performing cognitive rehabilitation training in the cognitive rehabilitation training unit (123), the dedicated cognitive rehabilitation chair (140) operates in conjunction, so that the movement of the chair unit (141) in all directions (front, back, up, down, left, and right), the hinge rotation of the backrest, and the hinge rotation of the headrest (142) are involved, allowing the subject seated in the chair unit (141) to perform cognitive rehabilitation training in an optimal posture. Furthermore, the multi-joint arm unit (147) supporting the monitor unit (146) can also be implemented as a type in which each joint is movable, and in this case, the joints move to change the position or direction of the monitor unit (146), thereby providing more immersive cognitive rehabilitation training to the subject seated in the chair unit (141).

[0061] The training results performed by the cognitive rehabilitation training execution unit (123) are provided to the evaluation result analysis unit (131), and the evaluation result analysis unit (131) evaluates and analyzes the training results.

[0062] The analyzed training results are transmitted to the rehabilitation history management unit (133) and accumulated as the rehabilitation history for the current subject. The rehabilitation history management data is processed as big data and, upon request from the subject or manager, is statistically processed and output through one of various user interfaces so that the requester can verify it.

[0063] If the training results for the current subject are analyzed to be below a threshold and the effect is determined to be poor, the training result data is transmitted to the content change matching recommendation unit (127), so that the content change matching recommendation unit (127) can change the content so that cognitive rehabilitation content more suitable for the current subject is matched.

[0064] In the process of changing and recommending content based on the training effect of the subject in the content change matching recommendation unit (127), machine learning is applied so that the relationship with previous training content and the analyzed growth effect are integrated to change and match the optimal cognitive rehabilitation content.

[0065] The new cognitive rehabilitation content recommended by the content change matching recommendation unit (127) is provided to the cognitive rehabilitation training execution unit (123), and the cognitive rehabilitation training execution unit (123) can execute the new cognitive rehabilitation content to allow the current subject to perform new cognitive rehabilitation training.

[0066] In addition, if the training results for the current subject are analyzed to exceed a threshold and it is determined that a growth effect is being shown, the cognitive function re-examination unit (125) can be activated to re-examine the cognitive function of the current subject.

[0067] This allows the current subject to be considered to have improved cognitive function to a certain level or higher as a result of cognitive rehabilitation training, and to compare the initial test data and re-test data performed in the initial cognitive function test module (110) and inform the growth effect.

[0068] In addition, the customized rehabilitation content recommendation unit (121) can reconstruct and recommend cognitive rehabilitation content using artificial intelligence based on the re-performed cognitive function test data.

[0069] FIG. 4 is a flowchart of a cognitive rehabilitation training method through user-customized content recommendation based on cognitive function test data according to an embodiment of the present invention.

[0070] Each step of the cognitive rehabilitation training method through user-customized content recommendation based on cognitive function test data according to the present embodiment can be performed by each component of the cognitive rehabilitation training system (10).

[0071] When a user (subject) is seated in the chair section (141), the user recognition unit provided in the monitor section (146) is activated to perform user recognition and activate each component of the chair section (141) to enable positioning (step S200). This takes into account the different body types of each user and allows the user to assume a suitable posture while performing cognitive function tests and cognitive rehabilitation training.

[0072] Here, the user recognition unit includes a camera, and identifies the user's face through image processing within an image captured by the camera, and determines whether the user's face is in a preset position (e.g., the center) and whether the user's face represents a preset size. If the user's face is not in the preset position, the direction of the monitor unit (146) is not facing the user directly, so each component of the chair unit (141) and / or each joint of the monitor unit (146) can be actuated to move from the recognized position to the preset position.

[0073] Alternatively, if the user's face does not display the set size, it is a situation where the distance to the monitor unit (146) is not correct, so each component of the chair unit (141) and / or each joint of the monitor unit (146) can be actuated to adjust the distance. For example, the chair unit (141) can be moved forward or backward on the stage (144), or the monitor unit (146) can be moved forward or backward.

[0074] When user recognition is complete, user login is performed (step S205). Since the user's identity can be verified through facial recognition, automatic login can be enabled if the user is already registered. If the facial recognition result indicates that the user is not already registered, the user is considered the first user, and user information including name, date of birth, gender, etc. is received and matched with the currently recognized user face to register the user in the user database.

[0075] Once user login is complete, the cognitive function test module (110) can perform a computerized cognitive function test (first) on the user seated in the chair (141) (step S210). An MMSE-K kit may be used for the cognitive function test.

[0076] When the cognitive function test is completed, the customized rehabilitation content recommendation unit (121) analyzes the test data and recommends customized cognitive rehabilitation content suitable for the user (step S215). For example, the content may be designed to enable intensive training for items that are judged to be deficient compared to the standard values ​​based on the test data.

[0077] In the cognitive rehabilitation training execution unit (123), recommended cognitive rehabilitation content is executed to allow the subject to perform cognitive rehabilitation training (step S220). Chair positioning may be performed during this process. This is because the appropriate user posture may differ depending on the cognitive rehabilitation content, and each component of the chair unit (141) and / or each joint of the monitor unit (146) may be operated to ensure that the appropriate posture is taken for each content.

[0078] The evaluation result analysis unit (131) analyzes the evaluation results after performing cognitive rehabilitation training (step S225). The evaluation results are transmitted to the rehabilitation history management unit (133) and can be managed as rehabilitation history in the user database (step S240).

[0079] If the analysis results in step S225 show a growth effect, the cognitive function re-examination unit (125) can be activated to re-perform the cognitive function test on the user (2nd to nth time) (step S230). The newly re-performed cognitive function test data can be transmitted to the customized rehabilitation content recommendation unit (121) and utilized in the process of recommending cognitive rehabilitation content.

[0080] If the analysis result in step S225 is poor, the content change matching recommendation unit (127) is activated so that the content can be changed to new content that can improve the effect in the current stage (step S235). Machine learning is applied during this process, and once the content change is made, the cognitive rehabilitation training execution unit (123) then performs cognitive rehabilitation training with the changed content.

[0081] Figure 5 is a diagram showing examples of items and scoring used in the MMSE-K kit, Figure 6 is a flowchart of the cognitive function test method performed in the cognitive function test module, Figure 7 is an example diagram of a computerized cognitive function test screen, and Figure 8 is an example diagram of a cognitive function test result screen.

[0082] Referring to FIG. 5, the MMSE-K kit, which is a computerized cognitive function test kit used in the cognitive function test module (110), may include items related to orientation, memory registration, memory recall, attention and calculation, language function, comprehension and judgment.

[0083] The items regarding orientation are as follows.

[0084] In question 1, the time question (0 to 5 points), you will be asked about today's date, and you may be asked again about any missing parts. Points are added for correct answers.

[0085] In the second address question (0 to 4 points), the address is asked, and points are added only for the correct answer. If the address is a special city or a metropolitan city, the question "What kind of place is this?" may be asked.

[0086] In question 3 (0 to 1 point), you may be asked the name of the place being examined.

[0087] The questions regarding memory registration are as follows.

[0088] In question 4 (0 to 3 points), you can tell the subject that you are testing their memory and call out three unrelated words (e.g., tree, car, hat) accurately and slowly at intervals of time (e.g., 1 second). Then, you can have them repeat this.

[0089] The items regarding memory recall are as follows.

[0090] In question 5 (0 to 3 points), you can ask the student to remember the three words mentioned earlier after a certain amount of time (e.g., 3 to 5 minutes).

[0091] The questions regarding attention and calculation are as follows.

[0092] In question 6 (0 to 5 points), you can have the student subtract a smaller number (e.g., 7) from a larger number (e.g., 100). Then, you can have the student repeat the calculation of subtracting the same smaller number from that number. Alternatively, you can have the student pronounce "Samcheolli Gangsan" backward.

[0093] The items regarding language function are as follows.

[0094] In the 7th name question (0 to 2 points), you can show a random image (e.g., a pencil and a clock) and ask for its name.

[0095] In question 8, the 3-step command problem (0 to 3 points), you can give a piece of paper to the subject and deliver a 3-step command.

[0096] In the 9th copy problem (0 to 1 point), you can show a picture of two overlapping pentagons and have the subject trace it.

[0097] In the 10-repeat problem (0 to 1 point), you can play a specific phrase (e.g., "Soy Sauce Factory Manager") and have the student repeat it.

[0098] The questions regarding understanding and judgment are as follows.

[0099] In question 11 (0 to 1 point), a question containing "why" (e.g., "Why do we wash our clothes before wearing them?") is asked, and the appropriateness of the answer to this question can be judged (as an example of an answer, an answer regarding hygiene ("to keep clean," "because it is dirty," etc.)).

[0100] In the 12th judgment question (0 to 1 point), a question containing "how" (e.g., "If you find someone else's ID card on the street, how can you easily return it to the owner?") is asked, and the appropriateness of the answer to this (an answer regarding the post office as an example) can be judged.

[0101] Referring to FIG. 6, the cognitive function test module (110) performs tests on six areas using a computerized MMSE as illustrated in FIG. 5. The test results can be classified into concentration, memory, orientation (visual perception), calculation ability, and executive function. Here, since the MMSE does not include visual perception, it can be processed together with orientation.

[0102] In this regard, the user's level for each area can be indicated by calculating and scoring a score for each area (processing the corresponding MMSE question as a percentage). The user's level can be determined as level 1 if it is lower than the threshold score (e.g., 60 points), and level 2 if it is higher.

[0103] Here, score calculation and grading can be performed as follows.

[0104] - Attention and calculation (concentration):

[0105] 5 subtraction problems x 20 points = 100 points

[0106] 2 points = 40 points (considered as 60 points or less)

[0107] 3 points = 60 points (considered 60 points or higher)

[0108] - Memory registration, recall (memory):

[0109] Scoring criteria 0–6 points, 16.6 points per point

[0110] 3 points = 50 points (considered as 60 points or less)

[0111] Classified as 4 points = 66 points (considered as 60 points or higher)

[0112] - Orientation (Orientation, Visual Perception): Scoring 0–10 points

[0113] = 10x10 = 100 points

[0114] - Verbal Function (Calculation): Scoring scale 0–7 points, 14.3 points per point

[0115] 4 points = 57.2 points (considered 60 points or less)

[0116] 5 points = 71.5 points (considered as 60 points or higher)

[0117] - Understanding and Judgment (Execution): 0~2 points

[0118] 1 point = 50 points (considered 60 points or less)

[0119] Classified as 2 points = 100 points (considered as 60 points or higher)

[0120] Referring to FIG. 7, an example of a computerized cognitive function test screen performed in a cognitive function test module (110) is shown. Each item may be displayed individually, and the results of the performance (such as ‘paper folded in half’ in the example), excluding eye movement or voice responses, may be entered separately through camera capture, etc.

[0121] Referring to Fig. 8, a cognitive function test result screen is shown. The answer content and scoring results for each item are displayed, and separately entered performance results may also be included as images.

[0122] Figure 9 is a diagram showing an automatic training content recommendation screen performed in a customized rehabilitation content recommendation unit, and Figure 10 is a diagram showing a design provision screen by an administrator.
