Technical Field

[0001] The present invention relates to the technical field of vestibulo-ocular reflex evaluation, and in particular to a vestibulo-ocular reflex function detection and evaluation system for evaluating whether the vestibulo-ocular reflex function is damaged based on the difference in visual discrimination accuracy rates in the detected static state and motion state. Background Art

[0002] Currently, for the evaluation of the function of the vestibular organ, mainly methods such as electronystagmogram and subjective gravity line are used for analysis. The impairment of the vestibulo-ocular reflex function may affect the stability of vision and lead to changes in visual resolution. How to evaluate the impairment of the vestibulo-ocular reflex function, there is currently no mature and marketed product to effectively solve this evaluation problem. Summary of the Invention

[0003] The present invention aims at the problems and deficiencies existing in the prior art, and provides a vestibulo-ocular reflex function detection and evaluation system and method.

[0004] The present invention solves the above technical problems through the following technical solutions:

[0005] The present invention provides a vestibulo-ocular reflex function detection and evaluation system, which is characterized in that it includes a treadmill, a random projection device, a transponder, and a control host, and the transponder has the letter E with different opening directions;

[0006] The control host is used to control the random projection device to randomly project the letter E with different font sizes and opening directions on the screen when the subject is in a static state, and each letter E with each font size is projected, and record the start timestamp of the projection of each letter E, the font size and the opening direction, receive the response signal sent by the subject through the transponder for each projected letter E, and record the response timestamp of the response signal and identify the opening direction of the letter E in the response signal, analyze and record the font size of each projected letter E, the reaction time of the subject, and whether the subject accurately identifies the opening direction of the letter E. The reaction time of the subject corresponding to the letter E = the response timestamp of the letter E - the start timestamp of the projection of the letter E. Whether the subject accurately identifies the opening direction of the letter E: if the opening direction of the projected letter E is consistent with the opening direction of the letter E in the response signal, the subject accurately identifies the opening direction of the letter E, otherwise the subject does not accurately identify the opening direction of the letter E;

[0007] The control host is further configured to control the treadmill to provide different running speeds and slopes to simulate different exercise intensities. When the subject is in N different exercise intensity states, it controls the random screen-casting device to randomly cast the letter "E" with different font sizes and opening directions on the screen, and each font size of the letter "E" is cast. It records the start timestamp of the casting of each letter "E", as well as the font size and opening direction, receives the response signal sent by the subject for each cast letter "E" through the transponder in each exercise intensity state, and records the response timestamp of the response signal and identifies the opening direction of the letter "E" in the response signal. It analyzes and records the font size of each letter "E" cast in each exercise intensity state, the reaction time of the subject, and whether the subject accurately identifies the opening direction of the letter "E". N is a positive integer;

[0008] The control host is further configured to analyze the minimum font size at which the subject can accurately identify the opening direction of the letter "E" in the static state, and the minimum font size at which the subject can accurately identify the opening direction of the letter "E" in each exercise intensity state. It calculates the actual difference value between the minimum font size at which the subject can accurately identify the opening direction of the letter "E" in each exercise intensity state and the minimum font size at which the subject can accurately identify the opening direction of the letter "E" in the static state, so as to obtain N actual difference values. It fits these N actual difference values with the function f(x) = ax + b to obtain the value of a, and determines whether the value of a is greater than the set threshold. If it is, it outputs the information that the subject's vestibulo-ocular reflex function is impaired; otherwise, it outputs the information that the subject's vestibulo-ocular reflex function is normal.

[0009] The present invention also provides a method for detecting and evaluating the vestibulo-ocular reflex function, which is characterized in that it includes the following steps:

[0010] When the subject is in a static state, the control host controls the random screen-casting device to randomly cast the letter "E" with different font sizes and opening directions on the screen, and each font size of the letter "E" is cast. It records the start timestamp of the casting of each letter "E", as well as the font size and opening direction, receives the response signal sent by the subject for each cast letter "E" through the transponder, and records the response timestamp of the response signal and identifies the opening direction of the letter "E" in the response signal. It analyzes and records the font size of each letter "E" cast, the reaction time of the subject, and whether the subject accurately identifies the opening direction of the letter "E". The reaction time of the subject corresponding to the letter "E" = the response timestamp of the letter "E" - the start timestamp of the casting of the letter "E". Whether the subject accurately identifies the opening direction of the letter "E": If the opening direction of the casting of the letter "E" is the same as the opening direction of the letter "E" in the response signal, the subject accurately identifies the opening direction of the letter "E"; otherwise, the subject does not accurately identify the opening direction of the letter "E".

[0011] The control host controls the treadmill to provide different running speeds and slopes to simulate different exercise intensities. When the subject is in N different exercise intensity states, the control host controls the random screen-casting device to randomly project the letter "E" with different font sizes and opening directions on the screen, and each font size of the letter "E" is projected. The start timestamp of the projection of each letter "E", as well as the font size and opening direction, are recorded. The response signals sent by the subject through the transponder for each projected letter "E" in each exercise intensity state are received, and the response timestamp of the response signal and the opening direction of the letter "E" identified in the response signal are recorded. The font size, the reaction time of the subject, and whether the subject accurately identifies the opening direction of the letter "E" for each projected letter "E" in each exercise intensity state are analyzed and recorded. N is a positive integer;

[0012] The control host analyzes the minimum font size at which the subject can accurately identify the opening direction of the letter "E" in the static state, and the minimum font size at which the subject can accurately identify the opening direction of the letter "E" in each exercise intensity state. The actual difference values between the minimum font size at which the subject can accurately identify the opening direction of the letter "E" in each exercise intensity state and the minimum font size at which the subject can accurately identify the opening direction of the letter "E" in the static state are calculated respectively to obtain N actual difference values. These N actual difference values are fitted with the function f(x) = ax + b to obtain the value of a, and it is determined whether the value of a is greater than the set threshold. If it is, the information that the subject's vestibulo-ocular reflex function is impaired is output; otherwise, the information that the subject's vestibulo-ocular reflex function is normal is output.

[0013] The positive and progressive effects of the present invention are as follows:

[0014] The present invention can accurately detect the vision of the human body in the static state and the exercise state, providing more comprehensive and accurate data for the evaluation of the vestibulo-ocular reflex function.

[0015] The present invention evaluates whether the vestibulo-ocular reflex function is normal or impaired by comparing the visual discrimination sensitivity of the human body in the static state and the exercise state, providing a new way for the early diagnosis of vestibular function-related diseases and providing a basis for formulating corresponding treatment and prevention measures. Using the detection and evaluation process of the present invention to evaluate the vestibulo-ocular reflex function can assist in diagnosing related symptoms caused by the decline of this vestibulo-ocular reflex function, such as helping to detect problems such as blurred vision when walking caused by the decline of this vestibulo-ocular reflex function.

[0016] The present invention has a simple structure and is easy to operate, and is applicable to various medical institutions, physical examination centers, scientific research institutions, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Figure 1 It is a structural block diagram of the vestibulo-ocular reflex function detection and evaluation system of a preferred embodiment of the present invention. Detailed implementation manners

[0018] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] As Figure 1 shown, this embodiment provides a vestibulo-ocular reflex function detection and evaluation system, which includes a treadmill 100, a random screen projection device 200, a wireless transponder 300, and a control host 400. The wireless transponder 300 has the letter E with different opening directions.

[0020] The control host 400 is configured to control the random screen projection device 200 to randomly project the letter E with different font sizes and opening directions on the screen and all the letters E with each font size are projected when the subject is in a static state, and record the start time stamp of the projection of each letter E, as well as the font size and opening direction; receive the response signal sent by the subject through the wireless transponder 300 for each projected letter E, record the response time stamp of the response signal and identify the opening direction of the letter E in the response signal, and analyze and record the font size of each projected letter E, the reaction time of the subject, and whether the subject accurately identifies the opening direction of the letter E.

[0021] Among them, the reaction time of the subject corresponding to the letter E = the response time stamp of the letter E - the start time stamp of the projection of the letter E.

[0022] Whether the subject accurately identifies the opening direction of the letter E: If the opening direction of the projected letter E is consistent with the opening direction of the letter E in the response signal, the subject accurately identifies the opening direction of the letter E; otherwise, the subject does not accurately identify the opening direction of the letter E.

[0023] Response scheme of the tested person: Equip the subject with a wireless transponder. After seeing the letter E on the screen, the subject indicates the opening direction of the letter E by pressing the corresponding button on the wireless transponder. The transponder is wirelessly connected to the control host to ensure the convenience and quickness of the subject's operation during the detection process, and at the same time, it can accurately record the reaction time and answer of the subject.

[0024] Further, when the subject is in a static state, for a certain projected letter E, it is determined whether the reaction time of the subject corresponding to this projected letter E is greater than the preset static feedback time. If so, it indicates that the reaction time of the subject is too long, and the subject's response is a random guess rather than observed by the eyes. Then, it is necessary to conduct another test. Thus, another letter E with the same font size as the projected letter E but a different opening direction is projected until the reaction time of the subject corresponding to the newly projected letter E is not greater than the corresponding preset static feedback time. Then, the projection of the next letter E with a different font size is carried out, and the font size of each projected letter E, the reaction time of the subject, and whether the subject accurately identifies the opening direction of the letter E within the preset static feedback time are analyzed and recorded.

[0025] For example: In a static state, the subject stands beside a treadmill or on a stationary treadmill 100, in a static state, and faces the screen for vision detection. At this time, the random projection device 200 randomly projects letters E with different font sizes and opening directions on the screen, and letters E of each font size are projected. The images of these letters E enter the subject's eyes through light reflection. The retina of the human eye receives the optical signal and converts it into a nerve signal to be transmitted to the brain's visual center for processing. After the subject visually identifies the opening direction of the letter E, the subject presses the button corresponding to the letter E with the opening direction on the wireless responder 300. In this way, the wireless responder 300 transmits the subject's response signal to the control host 400. The control host 400 records data such as the recognition accuracy of the subject for letters E of different sizes (whether the subject accurately identifies the opening direction of the letter E), the font size, and the reaction time from the appearance of the letter E to pressing the button.

[0026] The control host 400 is also used to control the treadmill 100 to provide different running speeds and slopes to simulate different exercise intensities. When the subject is in N different exercise intensity states respectively, the control host 400 controls the random projection device 200 to randomly project letters E with different font sizes and opening directions on the screen, and letters E of each font size are projected. The start timestamp, font size, and opening direction of each projected letter E in each exercise intensity state are recorded. The response signal sent by the subject for each projected letter E in each exercise intensity state is received through the wireless responder, and the response timestamp of the response signal and the opening direction of the letter E identified in the response signal are recorded. The font size of each projected letter E, the reaction time of the subject, and whether the subject accurately identifies the opening direction of the letter E in each exercise intensity state are analyzed and recorded, where N is a positive integer.

[0027] Further, when the subject is in any exercise intensity state, for a certain projected letter E, it is determined whether the reaction time of the subject corresponding to this projected letter E is greater than the preset exercise feedback time corresponding to this exercise intensity. If so, it indicates that the subject's reaction time is too long, and the subject's response is a random guess rather than an observation by the eyes, and re - detection is required. Then, a letter E with the same font size as the projected letter E but a different opening direction is projected again until the reaction time of the subject corresponding to the newly projected letter E is not greater than the corresponding preset exercise feedback time, and then the projection of the next letter E with a different font size is carried out. Analyze and record the font size of each projected letter E, the reaction time of the subject, and whether the subject accurately identifies the opening direction of the letter E within the corresponding preset exercise feedback time for each exercise intensity state.

[0028] When entering the exercise state detection, the subject runs on the treadmill 100, and the speed and slope of the treadmill 100 are adjustable to simulate different exercise intensities. During the running process, the subject's body is in a moving state, and the head and eyes will have movement - related changes such as shaking. At the same time, the random screen - casting device still projects the letter E on the screen. The subject observes the letter E during exercise. The retina receives continuously changing optical signals, and the brain's visual center processes these signals under the interference of body movement. The subject makes a judgment on the opening direction of the letter E in the exercise state and sends a signal to the control host 400 through the wireless responder 300. The control host 400 also records data such as the recognition accuracy of the subject for different - sized letter Es under different exercise intensities (whether the subject accurately identifies the opening direction of the letter E), the font size, and the reaction time from the appearance of the letter E to pressing the button. By comparing the data in the static state and the exercise state, the difference in visual resolution between the static and exercise states can be analyzed.

[0029] In the static state, the subject stands next to the treadmill or on a stationary treadmill, faces the screen, observes the letter E on the screen, and conducts a vision test. In the exercise state, the subject runs on the treadmill while observing the letter E on the screen and conducts a vision test.

[0030] The control host 400 is also used to analyze the minimum font size for the subject to accurately identify the opening direction of the letter E in the static state, and the minimum font size for the subject to accurately identify the opening direction of the letter E in each exercise intensity state, calculate the actual difference value between the minimum font size for the subject to accurately identify the opening direction of the letter E in each exercise intensity state and the minimum font size for the subject to accurately identify the opening direction of the letter E in the static state respectively, so as to obtain N actual difference values, perform function fitting on these N actual difference values with f(x)=ax + b to obtain the value of a, determine whether the value of a is greater than the set threshold, and when it is yes, output the information that the subject's vestibulo-ocular reflex function is impaired, otherwise output the information that the subject's vestibulo-ocular reflex function is normal.

[0031] This embodiment also provides a method for detecting and evaluating the vestibulo-ocular reflex function, which includes the following steps:

[0032] When the subject is in a static state, the control host 400 controls the random screen projection device 200 to randomly project letters E with different font sizes and opening directions on the screen, and each letter E with a different font size is projected, and records the start timestamp of the projection of each letter E, the font size and the opening direction, receives the response signal sent by the subject through the wireless transponder 300 for each projected letter E, and records the response timestamp of the response signal and the opening direction of the letter E recognized in the response signal, analyzes and records the font size of each projected letter E, the reaction time of the subject, and whether the subject accurately identifies the opening direction of the letter E. The reaction time of the subject corresponding to the letter E = the response timestamp of the letter E - the start timestamp of the projection of the letter E. Whether the subject accurately identifies the opening direction of the letter E: if the opening direction of the projected letter E is consistent with the opening direction of the letter E in the response signal, the subject accurately identifies the opening direction of the letter E, otherwise the subject does not accurately identify the opening direction of the letter E.

[0033] When the subject is in a static state, for a projected letter E, judge whether the reaction time of the subject corresponding to this projected letter E is greater than the preset static feedback time. When it is yes, project a letter E with the same font size and a different opening direction again until the reaction time of the subject corresponding to the re-projected letter E is not greater than the preset static feedback time, and then proceed to the projection of the next letter E with a different font size, and analyze and record the font size of each projected letter E, the reaction time of the subject, and whether the subject accurately identifies the opening direction of the letter E when the reaction time of the subject is within the preset static feedback time.

[0034] The control host 400 controls the treadmill 100 to provide different running speeds and slopes to simulate different exercise intensities. When the subject is in N different exercise intensity states, the control random screen-casting device 200 randomly projects the letter "E" with different font sizes and opening directions on the screen, and all letters "E" with different font sizes are projected. Record the start timestamp of the projection of each letter "E", the font size, and the opening direction in each exercise intensity state. Receive the response signal sent by the subject through the wireless transponder 300 for each projected letter "E" in each exercise intensity state, and record the response timestamp of the response signal and identify the opening direction of the letter "E" in the response signal. Analyze and record the font size of each letter "E" projected in each exercise intensity state, the reaction time of the subject, and whether the subject accurately identifies the opening direction of the letter "E". N is a positive integer.

[0035] Among them, when the subject is in any exercise intensity state, for a projected letter "E", it is judged whether the reaction time of the subject corresponding to this projected letter "E" is greater than the preset exercise feedback time corresponding to this exercise intensity. If so, project the letter "E" with the same font size but different opening direction again until the reaction time of the subject corresponding to the re-projected letter "E" is not greater than the corresponding preset exercise feedback time, and then proceed to the projection of the next letter "E" with a different font size. Analyze and record the font size of each letter "E" projected when the reaction time of the subject in each exercise intensity state is within the corresponding preset exercise feedback time, the reaction time of the subject, and whether the subject accurately identifies the opening direction of the letter "E".

[0036] The control host 400 analyzes the minimum font size at which the subject accurately identifies the opening direction of the letter "E" in the static state, and the minimum font size at which the subject accurately identifies the opening direction of the letter "E" in each exercise intensity state. Calculate the actual difference value between the minimum font size at which the subject accurately identifies the opening direction of the letter "E" in each exercise intensity state and the minimum font size at which the subject accurately identifies the opening direction of the letter "E" in the static state to obtain N actual difference values. Fit these N actual difference values with the function f(x)=ax + b to obtain the value of a, and judge whether the value of a is greater than the set threshold. If so, output the information that the subject's vestibulo-ocular reflex function is impaired, otherwise output the information that the subject's vestibulo-ocular reflex function is normal.

[0037] Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that these are only examples. The protection scope of the present invention is defined by the appended claims. Without departing from the principles and essence of the present invention, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
