Description

Technical Field

[0001] The present application belongs to the field of neuropsychology research, and in particular, relates to a video product and storage medium for inducing Parkinson's disease behavior. Background Art

[0002] Parkinson's disease (PD) is a common neurodegenerative disease in recent years and the most common movement disorder in the elderly. Its main clinical manifestations include motor symptoms such as resting tremor, slow movement, muscle rigidity and abnormal posture, and non-motor symptoms such as hyposmia, constipation, sleep disorders and depression. The disease cannot be cured, but early intervention can greatly alleviate the progression of the disease and improve the prognosis. Parkinson's disease has an insidious onset and gradually progresses. When patients seek medical treatment, the symptoms are often already obvious.

[0003] At present, the diagnosis of Parkinson's disease is mainly based on medical history, clinical symptoms and physical signs. The doctor will give a preliminary diagnosis based on the medical history provided by the patient and his own physical examination findings. After that, it is necessary to do a magnetic resonance imaging of the head, blood tests, electroencephalogram, electrocardiogram, etc. to rule out other diseases that may have symptoms of Parkinson's disease, such as post-stroke Parkinson's syndrome, drug-induced Parkinson's syndrome, traumatic Parkinson's syndrome and other diseases.

[0004] Therefore, the current diagnostic method for PD mainly relies on the physician's work experience and the patient's clinical manifestations, with a high misdiagnosis rate and failure to detect the disease early. Therefore, an objective, reliable and effective PD diagnosis and screening method is urgently needed. Summary of the invention

[0009] Furthermore, the target element of the third video clip is blurred after appearing for a first predetermined time, and appears at a new position after being blurred, and the new position is located at the edge area of ​​the subject's visual field, which is used to measure the subject's narrow vision ability.

[0010] Furthermore, the moving element only moves in the horizontal or vertical direction, which is used to measure the horizontal or vertical smooth tracking ability of the subject.

[0011] Furthermore, the interference element disappears after appearing for a second predetermined time.

[0012] Furthermore, the interference element and the target element of the third video clip are elements of the same type but in different forms.

[0013] Furthermore, the second video clip also displays scene elements with scene depth, which is used to measure the subject's visual depth perception ability for near and far.

[0014] Furthermore, the second video clip also displays an indicator element, and the indicator element is used to indicate the motion trajectory of the moving element, which is used to measure the subject's motion perception ability for trajectory prediction.

[0034] See also Figures 1 to 7 , Figures 1 to 7The schematic diagram of each video clip appearing in the video product for inducing Parkinson's disease behavior shown in the embodiment of the present application is captured from one of the video frames of the video clip. The video product in the present application can be shot in real life, or it can be produced by using animation, special effects and other technical means. The video product is used to display various animation or photography scenes and various elements in the scene for the subject to watch so that the subject can make action feedback, and the action feedback information is used to measure the subject's reaction ability and cognitive ability. Among them, the scene in the video usually refers to the background or environment in which the video appears, etc. It can be a three-dimensional scene or a plane scene with scene depth. The plane scene can be a simple color background, which can be fictional or real, or it can be various environmental scenes, such as outdoor or indoor scenes; the elements in the video usually refer to various objects, characters, and related colors, shapes, patterns, etc. that appear in the scene, and the elements, scenes, interactions between elements, and interactions between elements and scenes are used to induce the subject to make corresponding feedback after watching the video product. The feedback content includes but is not limited to eye movements, facial movements, limb behaviors, brain activities, etc. The eye movements can be tracked by an eye camera or an eye tracker to observe the feedback on the subject's eye behavior when watching the video product; the facial expressions and limb movements of the subject can be filmed by a camera to observe the subject's overall movement behavior; the brain activity can also be monitored by corresponding EEG acquisition equipment or magnetic resonance imaging equipment.

[0035] This video product is designed to further determine whether the subject has Parkinson's disease and Parkinson's-related diseases by evaluating reactions and cognitive abilities including but not limited to the ability to respond to rapidly changing visual stimuli, attention, smooth pursuit, etc.

[0036] Specifically, the video product for inducing Parkinson's disease behavior shown in the embodiment of the present application includes three video clips, wherein the first video clip shows target elements flashing at different positions, which is used to measure the subject's responsiveness to rapidly changing visual stimuli; the second video clip shows the process of at least one moving element continuously moving along a set path, which is used to measure the subject's smooth tracking ability; the third video clip shows the target element and the interference element, which is used to measure the subject's attention ability. Through this video product, the subject is induced to make corresponding behavioral feedback, and his reaction and cognitive ability are measured according to the behavioral feedback information, so as to screen, diagnose, treat and evaluate the efficacy of Parkinson's disease and Parkinson's disease-related diseases.

[0037] The video product of the present application includes three video clips or further includes more video clips similar to these three video clips. Each video clip can be a static image playback of a single image, or it can be a dynamic video composed of multiple continuous image frames. Among them, each video clip can be used to measure one or more of the above-mentioned reaction or cognitive abilities. For example, a certain video clip can measure both the smooth tracking ability of the subject and the visual depth perception ability of the subject. Each video clip is played according to the set timing, and the playback timing can be adjusted according to actual needs.

[0038] More specifically, in each video clip in this embodiment, the first video clip shows target elements flickering at different positions, which is used to measure the subject's ability to respond to rapidly changing visual stimuli; by comparing the eye movement trajectories and related key parameters of normal people and Parkinson's patients when tracking these flickering target elements, such as latency, peak velocity, saccade amplitude, saccade duration, time interval between two saccades, etc., it can assist in determining whether the subject has Parkinson's-related eye movement abnormalities. The second video clip shows the process of at least one moving element moving continuously along a set path, which is used to measure the subject's smooth tracking ability; when the moving element appears, it will attract the subject's attention, and the normal person's sight will follow the moving element; while the sight of patients with Parkinson's disease or Parkinson's-related diseases cannot normally follow the moving element. Preferably, in an exemplary embodiment, the moving element only moves horizontally or vertically, which is used to measure the subject's horizontal or vertical smooth tracking ability. The third video clip shows the target element and the distracting element, which is used to measure the subject's attention ability; the appearance of the target element will attract the subject's sight. When the target element appears or after the target element appears, one or more distracting elements will appear to distract the subject's sight. The subject's attention ability can be measured by observing the subject's reaction after seeing the target element and the distracting element. Figure 2 Shown is an implementation of the first video clip. Parkinson's disease patients suffer from basal ganglia dysfunction due to the degeneration of dopamine neurons in the substantia nigra of the midbrain, which leads to delayed movement initiation. This delay not only affects body movements, but also manifests itself in eye movements, especially the initiation time (latency) of spontaneous saccades is usually longer. Studies have shown that Parkinson's patients may have difficulty initiating saccades and react more slowly to rapidly changing visual stimuli, such as flashing objects. The first video clip is based on this feature and is used to induce special eye movement information for Parkinson's patients. Exemplary, Figure 2It shows a star that flashes continuously as a target element in four positions on the screen, namely the four corners of the rectangular screen, and the switching of the flashing star between different flashing positions will induce eye movement reaction. The figure only shows the static state. The star in the upper left corner is the target element that is flashing, so it is a relatively clear pattern; the stars in the other three corners are displayed in gray patterns, indicating that they are not flashing at this time, and indicating that they flash in other different time periods. It can be understood by those skilled in the art that the target element can also be replaced with patterns of other shapes, and the parameters such as the flashing duration and flashing at several positions can be adjusted according to specific needs. The flashing order of different positions can also be changed or random to prevent the subject from finding a specific flashing pattern. It is important to evaluate the characteristics of the subject's eye movement behavior when the flashing target element switches positions. Preferably, the flashing position is at the edge or corner of the screen or visual field, so that the eye movement behavior of Parkinson's patients with narrow vision can be better identified. In this embodiment, by comparing the eye movement trajectories and key parameters of normal people and Parkinson's disease patients when tracking the position changes of these flickering stars, the subject's ability to respond to rapidly changing visual stimuli can be measured, thereby assisting in determining whether the subject has Parkinson's disease-related eye movement abnormalities. Typically, when Parkinson's disease patients follow the changes in the flickering position of the target element, their eye movement behavior is relatively slow compared to that of normal people, which will be reflected in several parameters such as latency, saccade peak velocity, saccade amplitude, saccade duration, and the time interval between two saccades. Therefore, after obtaining the subject's eye movement behavior data, its ability to respond to rapidly changing visual stimuli can be determined, because this video clip will be able to induce special eye movement behavior in Parkinson's disease patients. Figures 3 to 5 2 is a different implementation of the second video clip. In the video clip shown, a person riding a horse moves from left to right, a person riding a bicycle moves from left to right, and three rockets rise from bottom to top. The moving elements are the person riding a horse, the person riding a bicycle, and the three rockets.

[0039] It is important to note that patients with Parkinson's disease or Parkinson's-related diseases have significantly different abilities to track horizontally or vertically moving objects than normal people, so the test results will be better in horizontally and vertically moving scenes. Figure 5 As shown, the moving elements are multiple rockets rising from bottom to top. By setting multiple moving elements at the same time, the subject's tracking ability for multiple horizontally or vertically moving objects can be tested, so as to further better measure the subject's tracking ability.

[0040] In one embodiment, the second video clip further displays scene elements with scene depth, which is used to measure the subject's visual depth perception ability for near and far.

[0041] like Figure 3 As shown in FIG. 1 , the scene element of the video clip is a real seaside scene with a depth of distance, and a person riding a horse moves from far to near. The visual depth perception ability of the subject can be measured by the scene with a depth of distance.

[0042] In one embodiment, the second video clip further displays an indicator element, wherein the indicator element is used to indicate the motion trajectory of the moving element, so as to measure the subject's motion perception ability for trajectory prediction.

[0043] like Figure 4 In the video clip shown, a person is riding a bicycle along the road from left to right, where the road is used as an indicator element of the moving element to indicate the movement trajectory of the moving element. A normal person can predict the movement trajectory of the moving element through the indicator element, and his / her sight may move to the next position where the moving element appears. Therefore, by setting the indicator element, the subject's motion perception ability for trajectory prediction can be further measured.

[0044] In an exemplary embodiment of the third video clip, the target element appears before the distracting element, and the distracting element appears at a set distance from the target element so that the distracting element is located at the edge of the subject's field of vision, which is used to measure the subject's narrow vision ability.

[0045] In one embodiment, if Figure 6 As shown in the figure, in this video clip, the target element is a blue balloon that appears from the right side of the video. The balloon appears from the bottom and moves to the top before disappearing. During this process, balloons of different colors such as red or white will appear on the left side of the video as interference elements. Normal people can quickly perceive the newly appeared balloons of different colors and divert their sight, but Parkinson's patients have narrow vision due to thin peripheral retina, so they may not be able to quickly perceive the new balloons of different colors that suddenly appear at the edge of vision. Therefore, this video clip can measure the ability to pay attention to sudden changes and the ability to pay attention to significant things.

[0046] In one embodiment, if Figure 7 As shown in the video clip, the target element is a burnt match, and the interference element is other normal non-burnt matches. The burnt match is obviously different from other normal matches. This video clip mainly measures the subject's ability to pay attention to significantly different elements by setting a different element that is obviously different among multiple identical elements. It is understandable that the elements can be replaced by other objects or patterns. Figure 7 A similar setting can be used to measure the ability to pay attention to salient things.

[0047] In some embodiments, the interference element and the target element are elements of the same type but in different forms. The interference has similar characteristics to the target element, and also has other different characteristics, which can better measure the subject's attention ability. Such as the unburned match and the burned match mentioned above. It can also be different characters; for example, in a video clip, when the video starts, the first character appears on the right side of the video, and after a certain period of time, the second character appears on the left side of the video, and after a short appearance, the second character moves and gradually disappears on the left side of the video; wherein the first character is the target element, and the second character is the interference element.

[0048] In an exemplary embodiment, the target element appears before the distracting element, and the distracting element appears at a set distance from the target element so that the distracting element is located at the edge of the subject's visual field, which is used to measure the subject's narrow vision ability.

[0049] For example Figure 6 As shown in the figure, in this video clip, the target element is the blue balloon that appears on the right side of the video. The balloon appears from the bottom and moves to the top before disappearing. During this process, new balloons of different colors such as red or white that appear on the left side of the video are at a certain distance from the target element. When the subject's line of sight is focused on the balloon of the target element, due to the thinner peripheral retina of Parkinson's patients, their field of vision is limited, and they cannot promptly perceive objects that appear in the edge area of ​​their visual field.

[0050] In some embodiments, for example, when the target element appears at the center of the video, the interference element appears at the edge of the video, that is, the above effect can be achieved by setting a set distance between the interference element and the target element, and the specific distance can be designed and adjusted according to the actual application scenario. Therefore, when the balloon as an interference element appears in the edge area of ​​the subject's field of vision, the Parkinson's patient cannot quickly perceive its appearance, which can measure the subject's narrow vision ability.

[0051] In some preferred embodiments, the interference element disappears after appearing for a second predetermined time, that is, other balloons as interference elements will move to the edge position and then gradually disappear after appearing, so that the narrow vision ability of the subject can be better tested. This is mainly because Parkinson's patients cannot quickly notice the balloons that appear, so in order to avoid the subject's diversion of sight due to other factors due to the balloon appearing for too long, resulting in inaccurate test results. Therefore, in order to further determine that the subject cannot perceive the interference elements at the edge of the visual field in a short time, it is preferred to perform the above-mentioned disappearance processing on the interference elements.

[0052] In one embodiment, the target element is blurred after appearing for a first predetermined time, and the target element appears at a new position after being blurred, and the new position is located at the edge of the subject's visual field, which is used to measure the subject's narrow vision ability. Figure 7 In the video clip shown, the burnt match is used as the target element. After blurring the target element, when it reappears at the edge of the video, Parkinson's patients are also unable to perceive the match reappearing at the edge.

[0053] In an exemplary embodiment, the video product includes a first video clip, three second video clips, and two third video clips that are played in sequence. In this embodiment, the video clips include Figures 2 to 7 By optimizing the combination of video clips, the duration of the video product can be further compressed while measuring the cognitive abilities of the subjects, thus improving the concentration of the subjects during the test and thus achieving the purpose of improving the accuracy of the final test results.

The communication bus 4002 may include a path for transmitting data between the processor 4001 and the memory 4003. The communication bus 4002 may be a PCI (Peripheral Component Interconnect) bus or an EISA (Extended Industry Standard Architecture) bus, etc. The communication bus 4002 may be divided into an address bus, a data bus, a control bus, etc. For ease of representation, only one thick line is used in the figure, but it does not mean that there is only one bus or one type of bus.

[0070] Optionally, the electronic device 4000 may further include a transceiver 4004, which may be used for data interaction between the electronic device and other electronic devices, such as data transmission and / or data reception.

[0075] In addition, an embodiment of the present application provides a storage medium having computer-readable instructions stored thereon, and the computer-readable instructions are executed by one or more processors to play the above-mentioned video product for inducing Parkinson's disease behavior.

[0076] Compared with the related art, this application constructs a video product composed of multiple video clips, and induces the subject to make behavioral feedback for Parkinson's disease or Parkinson's disease-related diseases through the respective or mutual changes between various elements and scenes in the video clips. Each video clip can measure one or more reactions or cognitive abilities of the subject, and based on the evaluation results of the subject's reactions and cognitive abilities, including at least the reaction ability to rapidly changing visual stimuli, attention ability, and smooth pursuit ability, the screening, diagnosis, treatment and efficacy evaluation of diseases such as Parkinson's disease, multiple system atrophy, and progressive supranuclear palsy are achieved. Through the application of this video product, the objectivity of the entire process of the above screening, diagnosis, treatment and efficacy evaluation is stronger, because the video product has a wide range of applicable scenarios, can be used as a paradigm of objective standards, can achieve fully standardized data collection and analysis, and is not affected by the subject's subjective influence, which also ensures that the results have higher reliability and consistency. The video product can be placed in a home scene or loaded in other removable devices with the help of a corresponding playback device, and it has a more flexible application scenario. In addition, the video product of this application can also be used in a variety of cultural levels and professional backgrounds. Even without any educational level, free observation of the video can still be completed. The entire implementation process only requires the operator to play the video product. The operator himself does not participate in the evaluation score, which greatly reduces the threshold of the application process and is easier to use. Moreover, there is often no fixed answer to the free observation of the video, and its learning effect is also weaker. By optimizing the combination of each video clip, the duration of the video product can be further compressed to improve the accuracy of various cognitive ability tests. The content of the video can also be adjusted according to the preferences of the subjects to improve the concentration of the subjects during the test, and the purpose of improving the test results can also be achieved.
