Description

Technical Field

[0001] This invention belongs to the field of motion detection device technology, and more specifically, relates to an integrated evaluation system for motion and cognitive functions based on data fusion. Background Technology

[0002] In modern medical rehabilitation, sports training, and cognitive science research, accurate assessment of individual motor and cognitive abilities is of great significance. Traditional methods of motor function assessment often focus on single-dimensional testing, such as analyzing only lower limb motor abilities or focusing only on simple upper limb motor responses. Cognitive ability assessments are also mostly conducted through independent tests, such as memory tests and attention tests, lacking a system that integrates motor and cognitive functions for comprehensive evaluation.

[0003] As research into the overall interaction mechanisms between the brain and body deepens, people have gradually realized the close connection between motor and cognitive functions. For example, when performing complex motor tasks, such as navigating a maze or operating complex machinery, cognitive resources need to be mobilized simultaneously to plan paths and solve potential problems. Conversely, a decline in cognitive ability can also affect an individual's motor performance. For instance, in the elderly, cognitive impairment is often accompanied by a higher risk of falls, reflecting that their motor abilities are also impaired to varying degrees.

[0004] A review of relevant publicly available technologies reveals several key solutions. One proposed system, WO2020176420A1, proposes a sports training system combining cognitive tasks and physical training. This system utilizes multiple input devices to generate ergonomically designed training programs that integrate cognitive and motor abilities, thereby improving the trainee's cognitive and motor coordination. Another proposed system, WO2015057471A3, provides a remote rehabilitation platform for restoring patients' cognitive and motor abilities. This platform allows therapists to interact remotely with patients, providing suitable programs and devices for interactive activities, facilitating convenient remote treatment. Finally, CN109688926B proposes a method for evaluating cognitive and motor disorders or impairments in suspected patients. This method involves running a detection program on a mobile device and having the test subject interact with it. The detection program's methods are adjusted in real-time to analyze the test subject's cognitive and fine motor abilities.

[0005] The above technical solutions all propose using various devices to combine the detection and training of patients' motor and cognitive abilities, but there are currently few efficient and simple integrated assessment systems that can specifically target the motor and cognitive abilities of the elderly.

[0006] The foregoing description of the background art is intended only to facilitate understanding of the invention. This description does not endorse or acknowledge any common general knowledge in the materials mentioned. Summary of the Invention

[0007] The purpose of this invention is to provide an integrated assessment system for motor and cognitive functions based on data fusion, belonging to the field of motion monitoring technology. The assessment system includes a server and an assessment platform connected to it. The interactive unit of the assessment platform issues instructions to the user according to assessment rules. The lower limb detection unit collects the user's movement data (A) on the platform, and the upper limb detection unit collects the user's movement data (B) through a top guide rail and a detection ball. The communication unit is responsible for data interaction with the server, and the control unit controls the upper limb detection unit to execute instructions. The assessment system analyzes the user's movement data based on assessment rules to evaluate the user's motor and cognitive abilities. The assessment rules include the server selecting suitable rules from multiple rules and generating final rules, as well as the server analyzing the user's movement data to generate real-time assessment data and subsequent assessment rules, achieving a comprehensive and dynamic assessment of the user's functions.

[0008] The present invention adopts the following technical solution: an integrated evaluation system for motor and cognitive functions based on data fusion, the evaluation system comprising: a server, and an evaluation platform communicatively connected to the server;

[0009] The evaluation platform includes:

[0010] The interaction unit is configured to send behavioral instructions to the user based on the evaluation rules;

[0011] The lower limb detection unit, installed on the central platform of the evaluation platform, is used to collect data on the user's nails during the evaluation process on the platform. Action data ;

[0012] An upper limb detection unit is located on the upper part of the evaluation platform, including a top guide rail and two or more detection balls suspended from the top guide rail to the front of the user; the detection balls include data collection of the user's action when touching the detection balls;

[0013] The communication unit is configured to submit the A to the server. Action data and B's action data, and receives the data specified by the server. Evaluation Rules ;

[0014] The control unit is configured to receive control instructions generated by the server according to the evaluation rules, so as to control the upper limb detection unit to execute the control instructions;

[0015] The evaluation system, based on the evaluation rules, combines and analyzes the data from Action A and Action B to evaluate the user's athletic and cognitive abilities.

[0016] Preferably, the lower limb detection unit includes a support platform and a sensor layer;

[0017] The support platform is made of a material that can absorb external impacts and is non-slip.

[0018] The sensor layer includes multiple sensors, at least used to detect the user's foot placement and foot pressure, in order to obtain the sensor layer. Action data .

[0019] Preferably, each of the detection balls is equipped with a B sensor group for detecting the timing of the user touching the detection ball and the movement state of the detection ball itself, and generating B action data.

[0020] Preferably, the detection ball is movably connected to the top guide rail by a drive unit; and the drive unit includes executing control commands to pull the suspended detection ball to change the position and / or height of the detection ball.

[0021] Preferably, the detection ball further includes an acoustic-optical unit, configured to emit a specified sound and / or a specified color of light at a specified time and / or frequency according to the control command of the control unit.

[0022] Preferably, the server includes one or more evaluation sub-rules selected from multiple existing evaluation sub-rules that are suitable for the current user's motor and cognitive abilities, and the evaluation rules are ultimately formed from multiple evaluation sub-rules.

[0023] Preferably, the server further includes generating real-time action data of the user by analyzing the action data of A and action data of B in real time, and generating subsequent evaluation rules based on the real-time action data and the personal information.

[0024] The beneficial effects achieved by this invention are:

[0025] 1. The evaluation system of this technical solution can organically combine the evaluation of motor ability and cognitive ability. Traditional evaluations often focus on either motor or cognitive function alone, while this system collects cognitive data from the user's touch of the detection ball and motor data from the lower limb detection unit, and analyzes the data based on unified evaluation rules. This allows for a comprehensive assessment of the user's cognitive performance during exercise and the impact of cognition on motor function, thus more accurately reflecting the user's overall ability status.

Furthermore, during the evaluation process, it can dynamically generate subsequent evaluation rules based on real-time evaluation data obtained from analyzing action data of user A and action data of user B. This adaptive mechanism can adjust the difficulty and tasks for different users at different evaluation stages, ensuring the validity and accuracy of the evaluation results and better adapting to individual differences.

[0027] 3. The evaluation platform of this technical solution adopts diverse interactive units and data acquisition methods. Interactive units send behavioral instructions to users based on evaluation rules, guiding them to complete corresponding actions. The mat and sensor layer of the lower limb detection unit can accurately collect information such as stepping position and force. The multiple detection balls of the upper limb detection unit can not only collect the timing of touch and their own movement state through internal sensor groups, but also change position and height under the control of the drive unit. Furthermore, with the help of the audio-visual unit, it provides various forms of stimulus feedback, enriching the dimensions of data acquisition and improving the richness and accuracy of the evaluation data.

[0028] 4. The software and hardware components of the evaluation system in this technical solution adopt a modular design. Each working module and component of the hardware component, as well as the instructions, parameters, and algorithms of the software component, can be easily replaced and / or upgraded later, thereby reducing the construction and maintenance costs of this system.

[0073] Further details are attached. Figure 4 The diagram illustrates the construction of the evaluation platform. (See attached diagram.) Figure 2 and attached Figure 4 The evaluation platform 300 is described below. For example, the evaluation platform 300 includes a lower limb detection unit 410, an upper limb detection unit 420, and an interaction unit 430; preferably, the communication unit 450 and the control unit 440 are disposed within the internal structure of the lower limb detection unit 410 and are not shown in the figures.

Preferably, the sensor layer is formed by a sensor matrix composed of multiple piezoresistive or piezoresistive sensors. Preferably, the sampling frequency of the sensor layer can be 60Hz or 120Hz, or higher; a higher sampling frequency can obtain more analysis data, but it will also consume more computing resources, and needs to be further determined by relevant technical personnel according to actual needs.

[0076] Preferably, sensor-based data can enable dynamic analysis of a user's stride length, cadence, gait cycle, and other parameters.

[0077] In some implementations, the user's lower limb symmetry index G is calculated using the following formula. By analyzing the comparison of the pressure on the left and right soles of the user, it is possible to analyze whether the pressure on the user's two legs is balanced.

[0078]

[0079] Among them, P L and P R These are the average single-foot pressure values ​​for the user's left and right feet, respectively.

[0080] In some implementations, the stability area of ​​the user's center of gravity projection point (COP) can be calculated using the following formula, and the stability of the COP can be analyzed to infer the user's balance ability and reflect the range of the human body's ability to maintain static or dynamic stability on the support surface. The COP (Center of Pressure) trajectory refers to the path of the center of pressure on the support surface during standing or movement.

[0084]

[0085] In the above formula, xt and yt are the coordinates of the user's center of gravity projection point COP on the bearing platform 411 at time t, respectively, and Δt is the detection step size, which can optionally be 0.1s or shorter.

[0086] In a preferred embodiment, the upper limb detection unit 420 is composed of a ring-shaped modular architecture, including a ring-shaped guide rail 421, a suspension mechanism 422, and a detection ball 423.

[0087] Preferably, the maximum outer diameter of the annular guide rail 421 is slightly larger than that of the support platform 411, and its diameter can be 2.2 meters or 2 meters, which is basically equivalent to or slightly larger than the user's arm span. The annular guide rail 421 is preferably made of a lightweight alloy such as aluminum alloy, and it consists of a main rail, a trolley module that can slide on the main rail by electric drive, and a deceleration drive system that drives the trolley module to move.

[0088] Furthermore, each trolley module is connected to a detection ball 423 via a carbon fiber cable, suspending the detection ball 423 around the user. Only two detection balls 423 are shown in the figure; in actual implementation, four or six detection balls 423 can be configured, increasing the versatility of detection combinations.

[0089] Preferably, the end of the trolley module can be equipped with a force sensor to detect the force acting on the detection ball, such as the tension generated by the carbon fiber cable when the user pulls the detection ball 423. The end of the trolley module can also be equipped with a quick connector to enable quick loading, unloading, and replacement of the detection ball 423.

[0090] Preferably, the detection ball 423 is further equipped with a second sensor, and the data generated by the second sensors of multiple detection balls 423 are packaged into a second sensor dataset for synchronous transmission to the server 200. The second sensor may include a 9-axis IMU capable of simultaneously sensing the acceleration and angular velocity of the detection ball 423 itself; the second sensor may also include a capacitive haptic array to sense the specific time and location at which the user touches the detection ball 423.

[0091] Preferably, LEDs are provided on the surface of the detection ball 423 so that the detection ball 423 displays the desired light color.

[0092] Preferably, a speaker is provided inside the detection ball 423; the speaker of each detection ball 423 can be connected to the control unit via wired or wireless connection, and the control unit can control one or more designated speakers to emit sound, and the control unit can determine that different detection balls 423 emit designated sounds, and control the sound volume, frequency and other parameters.

[0093] In other embodiments, the upper limb detection unit 420 may also be equipped with an image acquisition unit to obtain the user's dynamic posture during the evaluation, so as to obtain more analysis data.

[0094] Example 2: This example should be understood as including at least all the features of any of the foregoing examples, and further improving upon them.

[0095] In a preferred embodiment, the evaluation rules include determining the positional layout of a plurality of test balls 423.

[0096] Taking the circular annular guide rail 421 as an example, in this step, the initial distribution angle of each detection ball 423 is first defined:

[0097]

[0098] Where n = 1, 2, ..., N, N is the number of detection balls, and φ is the offset angle, which can be selected from 0° to 30°.

[0099] Furthermore, the motion of the detection ball 423 can be in linear oscillation mode, random walk mode, or static fixed-point mode, etc., to meet different detection needs and detection difficulties.

[0100] Furthermore, in the initial stage of the evaluation rules, the information processing unit 212 first extracts the user's basic information to determine the user's basic motor and cognitive abilities.

[0101] The user information that can be extracted includes height, upper limb length, lower limb length, body fat percentage, etc.

[0102] Preferably, the assessment of athletic ability also includes the user's static balance stability index, grip strength, hand strength, hand movement speed, and lower limb movement speed. Furthermore, the user's heart rate, blood pressure, and respiratory rate can be obtained through a monitoring device worn by the user.

[0103] Regarding cognitive abilities, an optional approach could be to perform a basic Stroop color-word conflict test, calculating the user's cognitive flexibility and the interference effect by detecting the degree of conflict between the LED color instructions of the ball and the voice prompts. Alternatively, an N-back working memory test could be conducted on the user to construct a spatial memory load using the emission sequence of the ball.

[0104] Preferably, in an exemplary embodiment, the following calculation formula can be used to update the difficulty coefficient D of the next detection sub-rule or multiple detection sub-rules in the next detection stage. next :

[0105]

[0106] In the above formula, D current A represents the difficulty level of the current detection sub-rule or the current detection phase. actual The actual score for the user executing the evaluation sub-rule; A expectedThe evaluation system predicts the expected score of the current user when executing an evaluation sub-rule; α is the difficulty adjustment sensitivity coefficient, which can be set by technical personnel based on the user's personal information, for example, 0.3 for healthy people and 0.15 for patients who have just recovered.

[0107] The actual score of a user executing an evaluation sub-rule can be determined independently for each evaluation sub-rule. For example, an evaluation sub-rule may specify that the user's reaction time, action speed, and touch accuracy (e.g., needing to touch the detection ball multiple times) in the action data need to be calculated, or it may also include consideration of the user's dynamic pulse, blood pressure, and other physical data.

[0108] In addition, B t To assess the baseline abilities of users' motor and cognitive functions in real time; P t β represents the user's maximum potential for real-time evaluation; β is the learning factor.

[0109] For example, a user's average reaction time might be 0.8 seconds, corresponding to an absolute reaction time score of 4, but the user's possible extreme reaction time might be 0.4 seconds, corresponding to an absolute reaction time score of 8; therefore, B can be simply set. t =4, P t =8. The above example is only for the convenience of understanding this technical solution. In actual settings, B... t and P t When setting a specific value, it needs to be determined by relevant technical personnel through a comprehensive evaluation of various user data based on an automated evaluation program.

[0110] Among them, B t The initial value B0 can be a comprehensive baseline value of ability calculated based on the user's basic physical condition, such as average blood pressure, respiratory rate, and pulse, obtained through preliminary simple tests, such as static standing and basic reaction tests; P t The initial value is P0, which is determined based on the user's age, medical history, and postural data (such as joint range of motion) to predict the potential limit of ability.

[0111] And the initial difficulty level D initial It can be set to: D initial =0.7B0+0.3P0.

[0112] D next The calculation formula includes an adaptive adjustment term in the first part, which reflects the dynamic adjustment of difficulty. The second part considers the comparison between the user's limit ability and the baseline ability. When the user is close to the limit, the degree of difficulty variation is reduced.
