Description

Technical Field

[0001] The present application relates to the field of computer technology, specifically to the field of smart medical technology, and in particular to a vestibular function rehabilitation program recommendation system and equipment. Background Art

[0002] Vestibular function refers to the vestibular part of the inner ear, including the semicircular canals and otolith organs, as well as the nerves and central systems associated with them. The vestibular system can be divided into the following parts: peripheral vestibular system (the peripheral vestibular system is located in the inner ear and includes the semicircular canals and otolith organs. These structures are responsible for detecting movement and position changes of the head), vestibular nerve (the vestibular nerve transmits sensory information from the semicircular canals and otolith organs to the central nervous system), central vestibular system (the central vestibular system is located in the central nervous system and includes the vestibular nuclei of the brainstem and multiple nuclei and pathways of the cerebellum. These structures integrate and process information from the peripheral vestibular system), vestibulo-ocular reflex system, and vestibulospinal reflex system.

[0003] Vestibular dysfunction leads to asymmetric vestibular signal conduction on both sides, causing vertigo in patients. According to the location of the lesion, vertigo is divided into central vestibular vertigo and peripheral vestibular vertigo. Peripheral vestibular vertigo is the most common, accounting for about 50%-70%. Vertigo is a direct pathological manifestation of vestibular dysfunction, and nystagmus is a direct manifestation of vertigo. Vertigo is accompanied by different forms of nystagmus.

[0004] Relationship between nystagmus and vestibular function:

[0005] The mechanism of nystagmus involves a complex interaction between the vestibular system, the visual system, and the central nervous system. The following are the main mechanisms of nystagmus:

[0006] The vestibulo-ocular reflex (VOR) is an important mechanism of nystagmus. The VOR is responsible for stabilizing the line of sight during head movement, allowing the eyes to stay fixed on a target. This reflex involves several steps: Vestibular receptors - the semicircular canals and otolith organs in the inner ear detect angular and linear acceleration of the head. Vestibular nerves - transmit signals to the vestibular nuclei in the brainstem. Vestibular nuclei - integrate this information and send commands to the motor neurons of the extraocular muscles. Extraocular muscles - execute these commands and adjust the position of the eye to compensate for the movement of the head. When there is an abnormality in the vestibular system (such as vestibular neuritis or inner ear disease), the VOR will be disturbed, resulting in involuntary rhythmic movements of the eye, i.e. nystagmus.

[0007] Different types of nystagmus can help distinguish whether the vestibular system lesions occur peripherally (such as the inner ear or vestibular nerve) or centrally (such as the brainstem or cerebellum). For example, peripheral nystagmus is usually unidirectional and changes with the position of the head, while central nystagmus may be multi-directional and does not change with the position of the head. By observing nystagmus, doctors can diagnose a variety of vestibular system diseases. For example: Benign paroxysmal positional vertigo (BPPV): specific head movements trigger brief nystagmus and vertigo. Meniere's disease: may cause spontaneous nystagmus and accompanying hearing loss. Vestibular neuritis: causes persistent unidirectional nystagmus and severe vertigo. By regularly observing and recording changes in nystagmus, doctors can monitor the progression and treatment effectiveness of vestibular diseases. Improvement or worsening of nystagmus can reflect changes in the condition, thereby guiding adjustments to the treatment plan.

[0008] In the current clinical program, doctors use nystagmus to observe the direction and speed of patients' nystagmus and roughly determine the affected area of ​​vestibular function. However, the evaluation method is single and the specific diagnosis of the disease depends on the doctor's subjective experience. The corresponding rehabilitation program usually relies on the subjective evaluation of medical staff.

[0009] That is, the existing methods for determining rehabilitation programs have the following shortcomings:

[0010] 1. The existing scheme relies solely on electronystagmography to evaluate the diseased area of ​​vestibular function. The technical means are single and can only meet the screening of diseases of the peripheral vestibular system. The coverage is low and cannot meet the doctor's needs for full-scenario clinical diagnosis of vestibular function.

[0011] 2. In the process of formulating existing vestibular function rehabilitation programs, it is usually dependent on the subjective evaluation of medical staff, that is, medical staff observe the user's behavior and formulate training programs for the user based on experience. However, the study found that the above method may be limited by the lack of experience of medical staff, interference from human factors and the influence of subjective judgment, resulting in the problem of low effectiveness of the determined rehabilitation training program; at the same time, due to the lack of objective quantitative data based only on the naked eye observation of the user's behavior by medical staff, the accuracy of the determined rehabilitation training program is low. Summary of the invention

[0012] Aiming at the technical problem that the rehabilitation training programs determined in the prior art have low accuracy, a vestibular function rehabilitation program recommendation system and device are provided.

[0013] According to a first aspect, a vestibular function rehabilitation program recommendation system is provided, comprising:

[0014] A head-mounted device for obtaining various nystagmus test data while a target subject is undergoing various vestibular function tests;

[0015] A lesion assessment module is used to determine test data corresponding to different subsystems in the vestibular system from a variety of nystagmus test data, and to determine whether each subsystem has a lesion based on the test data corresponding to each subsystem, thereby obtaining lesion assessment results for all subsystems in the vestibular system;

[0016] The rehabilitation program recommendation module is used to determine a rehabilitation training program suitable for the target object based on the lesion evaluation results of all subsystems in the vestibular system.

[0017] According to a second aspect, an electronic device is provided, comprising any of the above-mentioned vestibular function rehabilitation program recommendation systems.

[0018] According to the scheme of the present application, it is proposed to obtain a variety of nystagmus test data during the process of the target object undergoing a variety of vestibular function tests, and to judge whether each subsystem of the vestibular system has a lesion based on the various nystagmus test data, so that the lesions of each subsystem in the vestibular system can be intelligently and automatically evaluated based on more comprehensive and effective test data, making the lesion evaluation process more comprehensive, reliable and effective, and avoiding the influence of individual differences caused by manual evaluation, which is conducive to improving the effectiveness and accuracy of the lesion evaluation results; and then based on the effective and accurate lesion evaluation results, a rehabilitation training plan suitable for the target object is intelligently and automatically determined, further avoiding the interference of human factors and the influence of subjective judgment brought about by the manual determination of the rehabilitation training plan, which is conducive to improving the effectiveness, accuracy and adaptability of the rehabilitation training plan.

[0019] Other features, objects and advantages of the present application will become more apparent by reading the detailed description of non-limiting embodiments made with reference to the following drawings:

[0020] Figure 1 is an exemplary system architecture diagram to which some embodiments of the present application can be applied. DETAILED DESCRIPTION

[0021] The following is a description of exemplary embodiments of the present application in conjunction with the accompanying drawings, including various details of the embodiments of the present application to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0022] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0023] Figure 1An exemplary system architecture 100 is shown to which an embodiment of the vestibular function rehabilitation program recommendation system of the present application can be applied.

[0024] like Figure 1 As shown, the system architecture 100 may include a terminal device head mounted device 101, a network 102, a lesion assessment module 103, and a rehabilitation program recommendation module 104. The network 102 is used to provide a medium for a communication link between the head mounted device 101, the lesion assessment module 103, and the rehabilitation program recommendation module 104. The network 102 may include various connection types, such as wired, wireless communication links, or optical fiber cables, etc.

[0025] The user can use the head mounted device 101 to interact with the lesion assessment module 103 and the rehabilitation plan recommendation module 104 through the network 102 to receive or send messages, etc.

[0026] The head mounted device 101 here may be any eye tracker capable of collecting eye movement data, performing eye movement tests, and voice interaction.

[0027] The lesion assessment module 103 and the rehabilitation program recommendation module 104 may be independent computing devices with computing capabilities (such as computers, servers), or may be two functional modules integrated in the same computing device.

[0028] Continue to refer Figure 1 The functions of each component in the vestibular function rehabilitation program recommendation system 100 of the present application are introduced as follows:

[0029] The head mounted device 101 is used to obtain various nystagmus test data during the process of the target subject performing various vestibular function tests;

[0030] The lesion assessment module 102 is used to determine the test data corresponding to different subsystems in the vestibular system from the multiple nystagmus test data, and determine whether each subsystem has a lesion according to the test data corresponding to each subsystem, so as to obtain the lesion assessment results of all subsystems in the vestibular system;

[0031] The rehabilitation program recommendation module 103 is used to determine a rehabilitation training program suitable for the target object according to the lesion assessment results of all subsystems in the vestibular system.

[0032] In some optional implementations of this embodiment, for example, the head-mounted device 101 can be an eye tracker that performs eye movement testing and test data collection based on infrared light. After the user confirms that the head-mounted device 101 is properly worn, the infrared optical sensor equipped with the eye tracker senses and captures the infrared light reflected by the eyeball while the user's eyes are looking forward. The infrared optical sensor is usually located in the camera part of the eye tracker. The infrared optical sensor converts the captured reflected light into an electrical signal and transmits it to a computer for data processing. The computer uses the received reflected light signal to calculate the position and movement trajectory of the eyeball to obtain the movement information of the user's eyeball in real time. Based on the movement information of the eyeball, it can be determined whether there is nystagmus. Before conducting a formal test, the user's eye position can be calibrated based on the pupil position of the user's eyes; the user's binocular visual angle is calibrated by the user's eyes following the calibration test target in the virtual scene displayed in the head-mounted device.

[0033] In some optional implementations of this embodiment, the above-mentioned multiple vestibular function tests may include multiple eye movement tests for testing different nystagmus conditions, for example, spontaneous nystagmus test (SH1), gaze test (SH2), saccade test (SH3), optokinetic test (SH4), smooth pursuit test (SH5), saccade sinusoidal tracking test (SH6), position test (SH7), rotation test (SH8), temperature test (SH9), voice scale (YS1), voice scale (YS2) and voice scale (YS3), etc. The induced tests are respectively conducted on the user in different positions and different environments, and the nystagmus test data such as the direction, rotation direction, duration, gaze range, etc. of the test user's eyeball nystagmus are actually recorded. Through the preset voice evaluation scale, the user is actively questioned after the test process to determine the time when nystagmus occurs, the discomfort when nystagmus occurs, or the location of vestibular disease onset. According to user tests, nystagmus test data were obtained under tests such as spontaneous nystagmus test (SHJ1), gaze test (SHJ2), saccade test (SHJ3), optokinetic test (SHJ4), smooth pursuit test (SHJ5), saccadic sinusoidal pursuit test (SHJ6), positional test (SHJ7), rotation test (SHJ8), temperature test (SHJ9), first speech scale (YSJ1), second speech scale (YSJ2) and third speech scale (YSJ3).

[0034] For example, the spontaneous nystagmus test (SH1): the user looks straight ahead at a fixed bright spot with eyes open for 30 seconds to collect test data such as whether nystagmus occurs, the direction of nystagmus, rotation direction, duration, gaze range, etc.

[0035] Gaze test (SH2): The user gazes at a target bright spot offset by 30 degrees in the four directions of up, down, left, and right. If nystagmus occurs, the entire process is recorded.

[0036] Saccade test (SH3): The user stares at a bright spot in front of the field of vision that moves rapidly horizontally, generally at a viewing angle of 20 degrees per second, to collect test data such as whether nystagmus occurs, the direction of nystagmus, rotation direction, duration, and gaze range.

[0037] Visual dynamics test (SH4): The user looks at a screen full of bright spots in the front field of view, moving in one direction at a constant speed, and collects test data such as whether nystagmus occurs, the direction of nystagmus, rotation direction, duration, gaze range, etc.

[0038] Smooth pursuit test (SH5): The user looks at bright spots with uneven horizontal motion in the visual field, and collects test data such as whether nystagmus occurs, the direction of nystagmus, rotation direction, duration, and gaze range.

[0039] Saccade sinusoidal tracking test (SH6): The user looks at the bright spots that appear in the visual field and move at different speeds. Test data such as whether nystagmus occurs, the direction of nystagmus, rotation direction, duration, and gaze range are collected.

[0040] Positional test (SH7): The user detects spontaneous nystagmus while in different positions on the examination table.

[0041] Rotation test (SH8): The user lowers his head 30 degrees to look at a rotating light wheel that appears in his field of vision, and then suddenly stops. Test data such as whether nystagmus occurs, the direction of nystagmus, rotation direction, duration, and gaze range are collected.

[0042] Temperature test (SH9): Use 250ml of 30°C and 44°C water to pour into the user's left and right ears respectively, each pouring time is 30 seconds. There should be at least 5 minutes between two pouring times. The pouring order is: right ear 44°C, left ear 44°C, right ear 30°C, left ear 30°C, to see if nystagmus occurs.

[0043] The first voice scale (YS1), the second voice scale (YS2) and the third voice scale (YS3) are questionnaire scales set up for the peripheral vestibular subsystem, the central subsystem and the nervous subsystem respectively. The questionnaire scales include nystagmus-related questions such as when nystagmus occurs, which vestibular position is uncomfortable when nystagmus occurs, and what are the symptoms of discomfort when nystagmus occurs. In the process of voice scale testing, questions are asked to the user by voice through the above-mentioned head-mounted device, and different answer options are displayed to the user. The answer to each question selected by the user is determined based on the collected eye movement data of the user (for example, the answer option that the eye is fixated on is the answer selected by the user).

[0044] In some optional implementations of the present embodiment, in order to effectively and accurately evaluate whether each subsystem in the vestibular system has a lesion and the type of lesion, it is proposed to determine a plurality of test data corresponding to different subsystems in the vestibular system from a plurality of nystagmus test data. For example, the subsystems in the vestibular system include a peripheral vestibular subsystem, and the test data corresponding to the peripheral vestibular subsystem include test data of a spontaneous nystagmus test, test data of a positional test, test data of a temperature test, and test data based on a first speech scale.

[0045] For example, the subsystems in the vestibular system include the vestibular nerve subsystem, and the test data corresponding to the vestibular nerve subsystem includes test data of spontaneous nystagmus test, test data of saccade sinusoidal tracking test, test data of positional test and test data based on the second speech scale.

[0046] For example, the subsystems in the vestibular system include a central vestibular subsystem, and the test data corresponding to the central vestibular subsystem include test data of a spontaneous nystagmus test, test data of a gaze test, test data of a saccade test, test data of a visual kinematic test, test data of a smooth pursuit test, test data of a saccade sinusoidal tracking test, test data of a rotation test, test data of a temperature test, and test data based on a third speech scale.

[0047] In some optional implementations of this embodiment, in order to more accurately perform disease assessment based on a variety of test data for each subsystem, it is proposed to perform disease assessment based on the deviation between the test data and the corresponding test data of healthy persons. For example, the lesion assessment module includes:

[0048] A data processing unit, for calculating the deviation between each test data and the test data of a healthy person, for a plurality of test data corresponding to each subsystem of the vestibular system;

[0049] The lesion evaluation unit is used to calculate the probability of whether the subsystem has a lesion according to the deviation and weight corresponding to each test data.

[0050] In some optional implementations of this embodiment, in order to perform disease assessment more efficiently and accurately, the lesion assessment unit is also used to determine that there is a lesion in the subsystem if the probability is greater than a first threshold; if the probability is less than the first threshold and greater than a second threshold, then it is determined that there is a possibility of a lesion in the subsystem; if the probability is less than the second threshold, then it is determined that there is no lesion in the subsystem, wherein the first threshold is greater than the second threshold.

[0051] In some optional implementations of this embodiment, the specific numerical values ​​of the first threshold and the second threshold can be determined based on factors such as evaluation accuracy and disease characteristics.

[0052] In some optional implementations of this embodiment, the lesion assessment unit is proposed, which is used to calculate the probability of whether the subsystem has a lesion according to the deviation and weight corresponding to each test data by the following formula:

[0053]

[0054] Wherein, P represents the probability, A1% represents the deviation degree (for example, data deviation, abnormality rate, etc.) between the first test data of the multiple test data corresponding to the subsystem and the first test data of the healthy person (i.e., the person with healthy vestibular function), A2% represents the deviation degree between the second test data of the multiple test data corresponding to the subsystem and the second test data of the healthy person, and A i % represents the deviation between the ith test data of the subsystem and the ith test data of the healthy person. n % represents the deviation between the nth test data of the multiple test data corresponding to the subsystem and the nth test data of the healthy person, n represents the total number of test data corresponding to the subsystem, C1 represents the weight of the first test data of the multiple test data corresponding to the subsystem, C2 represents the weight of the second test data of the multiple test data corresponding to the subsystem, C i represents the weight of the i-th test data among the multiple test data corresponding to the subsystem, C n Indicates the weight of the nth test data among the multiple test data corresponding to the subsystem.

[0055] In some optional implementations of the present embodiment, in order to further accurately determine a rehabilitation training plan for the disease of each subsystem, a rehabilitation plan recommendation module is proposed, which is used to match the lesion assessment results of all subsystems in the vestibular system with a historical case sample set to determine matching historical case samples. If it is determined based on the historical case samples that the lesions of the subsystems in the vestibular system require rehabilitation training, a rehabilitation training plan suitable for the target object is determined based on the lesions existing in all subsystems in the vestibular system.

[0056] In some optional implementations of this embodiment, each case sample in the historical case sample set includes diagnostic information such as the subsystem in which the disease occurs, the type of disease, and whether rehabilitation training is required.

[0057] The matched historical case samples mentioned above have the same disease type and vestibular location of the lesion as the lesion assessment results of the target subject.

[0058] In some optional implementations of the present embodiment, in order to efficiently and accurately determine a comprehensive, adaptive, and personalized rehabilitation training program, a rehabilitation program recommendation module is proposed, which is used to determine the rehabilitation training sub-items corresponding to the lesions existing in each subsystem of the vestibular system according to the correspondence between pre-stored lesions (for example, lesion type, lesion location) and rehabilitation training sub-items, and integrate the rehabilitation training sub-items corresponding to the lesions existing in all subsystems of the vestibular system into a rehabilitation training program adapted to the target object.

[0059] In some optional implementations of this embodiment, the rehabilitation program recommendation module can also be a trained neural network model. The data such as the lesion type and lesion location of all subsystems in the vestibular system are input into the neural network model, and the corresponding rehabilitation training program is output.

[0060] In some optional implementations of this embodiment, the above-mentioned rehabilitation training sub-items may be rehabilitation training movements corresponding to different vestibular diseases, and the rehabilitation training movements may be implemented with reference to existing rehabilitation training movements.

[0061] In some optional implementations of the present embodiment, the process of integrating the rehabilitation training sub-items corresponding to the lesions existing in all subsystems of the vestibular system into a rehabilitation training program adapted to the target object may be a process of deleting duplicate rehabilitation training sub-items and setting a training sequence and a training duration for different rehabilitation training sub-items.

[0062] In this embodiment, the present application provides an electronic device, and any of the above-mentioned vestibular function rehabilitation program recommendation systems can be specifically applied to various electronic devices.

[0063] The modules and units involved in the embodiments described in this application may be implemented by software or hardware. The names of these modules and units do not, in some cases, limit the units themselves. For example, the lesion assessment module may also be described as a "module for assessing vestibular system lesions".

[0064] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above invention concept. For example, the above features are replaced with the technical features with similar functions disclosed in this application (but not limited to) by each other to form a technical solution.
