Description

Technical Field

[0001] This invention relates to the field of functional movement screening equipment technology, specifically to a functional movement screening test method and a portable intelligent test device. Background Technology

[0002] Functional Movement Screening (FMS) assesses an individual's motor control and symmetry through seven basic movements (squat, hurdle step, straight lunge, shoulder flexibility, active leg raise, trunk stability push-up, and rotational stability test), and is widely used in sports protection and rehabilitation. However, existing FMS tests rely on on-site observation and subjective scoring by professionals, resulting in low efficiency, poor consistency, and susceptibility to human error. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the purpose of this invention is to provide a portable intelligent testing device to solve or alleviate the aforementioned technical problems in the prior art.

[0004] To achieve the above objectives, in one aspect, the present invention provides a functional movement screening test method, comprising:

[0005] S1. Before the test, play a video demonstrating the standard movements to the subject and simultaneously output voice explanation;

[0006] S2, during the testing process, simultaneously collects data from multiple sources;

[0007] S3, based on the multi-source data, identify the relative angle between the torso and lower limbs and the position of key joints, detect the off-ground status or displacement of the supporting parts, and determine whether the test auxiliary device maintains the preset posture.

[0008] S4, based on the judgment result of S3, matches it with the preset FMS scoring rule library to generate quantitative scores and deviation location information;

[0009] S5. After the test is completed, output an evaluation report containing the quantitative score and deviation location information.

[0010] On the other hand, the present invention also provides a portable intelligent testing device, comprising:

[0011] A main unit equipped with a display screen and speakers;

[0012] A vision acquisition module electrically connected to the host computer is used to acquire the motion image sequence and transmit it to the host computer.

[0013] A mechanical sensing module electrically connected to the host computer is used to acquire the pressure distribution time-series data and transmit it to the host computer; and

[0014] A test auxiliary device is equipped with an attitude sensing module, which is electrically connected to the host computer. The attitude sensing module is used to acquire the spatial attitude data and transmit it to the host computer.

[0015] The host is configured as follows:

[0016] Based on the multi-source data acquired by the visual acquisition module, the mechanical perception module, and the posture perception module, the subject is guided in real time through voice prompts and dynamic guidance videos. The multi-source data is then integrated and analyzed to automatically determine the standardization of the movements and generate a scoring result.

[0017] Furthermore, the testing aid includes multiple coaxially arranged and detachably connected rods, adjacent rods are detachably coaxially connected through an end connection structure, and at least one rod is embedded with the attitude sensing module.

[0018] Furthermore, the end connection structure is any one of a threaded structure, a snap-fit ​​structure, a magnetic structure, or a plug-in quick-installation structure.

[0019] Furthermore, the biomechanical sensing module includes a full-body support monitoring pad and a foot positioning monitoring pad. The full-body support monitoring pad is used to monitor the support status during squats or straight lunges, and the foot positioning monitoring pad is used to monitor the support status of one foot during hurdles or shoulder flexibility tests.

[0020] Furthermore, the mechanical sensing module includes a mechanical sensing layer, which is electrically connected to the host, and the mechanical sensing layer is at least one of a pressure sensor array, a flexible force-sensitive film, a piezoelectric sensing layer, an electronic fabric, or a distributed tactile sensing element.

[0021] Furthermore, it also includes a hurdle frame, which includes two support frames and a crossing indicator mounted between the tops of the two support frames;

[0022] The support frame is a telescopic or foldable structure and has multi-level height adjustment function; the hurdle indicator is used to provide subjects with a visual and spatial reference benchmark for hurdle height during the hurdle test.

[0023] Furthermore, the support frame includes:

[0024] The central column includes an outer column, an inner column coaxially slidably inserted into the outer column, and a height adjustment mechanism disposed between the outer column and the inner column, the height adjustment mechanism being used to adjust the extension length of the inner column;

[0025] At least three support legs evenly arranged around the axis of the central column, the support legs being hinged to the outer column; and

[0026] An unfolding locking mechanism is provided between the support leg and the central column to lock the support leg when it is unfolded.

[0027] Furthermore, the height adjustment structure includes:

[0028] A nut, wherein the nut is disposed within the inner cylinder and slidably connected to the inner cylinder along the axial direction, and the nut is fixedly connected to the inner wall of the bottom end of the outer cylinder via a connecting shaft; and

[0029] A screw is coaxially inserted into the inner cylinder, the screw is rotatably connected to the inner cylinder, and the screw is threadedly connected to the nut.

[0030] Furthermore, the deployment locking mechanism includes:

[0031] A slider, wherein the slider is slidably connected to the support leg along its length; and

[0032] A locking lever, the first end of which is hinged to the slider and the second end of which is hinged to the central post.

[0033] Furthermore, the main unit is equipped with a portable handle and / or a dedicated storage bag.

[0034] The beneficial effects of this invention are:

[0035] The portable intelligent testing device provided by this invention employs a multi-source sensing architecture that coordinates the visual acquisition module, the mechanical sensing module, and the built-in posture sensing module of the testing aid. The host performs data fusion analysis, enabling the system to simultaneously acquire multi-dimensional objective data such as the subject's visual posture, foot biomechanical state, and the spatial orientation of the testing aid. This solves the problems of inconsistent assessment results and low reliability caused by traditional functional movement screening relying on manual visual observation and subjective scoring.

[0036] Because the mechanical sensing module is configured to detect local mechanical interaction information such as heel lift-off and supporting foot displacement, the host can accurately identify foot violations during squat or hurdle step tests, thus solving the technical problem that existing vision systems cannot accurately determine whether the sole of the foot is completely on the ground or has slipped.

[0037] Because the test aid is equipped with an embedded posture perception module, the host can accurately and in real time determine the posture of the test aid (such as whether it is level) without relying on external visual calibration. This solves the problem of inaccurate shoulder flexibility or hurdle step scoring caused by the visual acquisition module being unable to stably track the posture of a slender rod in environments with poor lighting, obstruction, or limited viewing angle.

[0038] Because the host is configured to perform real-time analysis based on multi-source data during the test and output voice prompts and dynamic visual guidance synchronously through speakers and displays, subjects can complete standardized actions independently without on-site guidance from professional personnel. This solves the problems of traditional FMS testing, such as high dependence on professional evaluators, low testing efficiency, and difficulty in widespread application. Attached Figure Description

[0051] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0052] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application should have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0053] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0054] Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly defined.

[0055] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0057] Example 1

[0058] like Figure 1 As shown, the present invention provides a functional movement screening test method, comprising:

[0059] S1. Before the test, play a video demonstrating the standard movements to the subject and simultaneously provide audio explanations.

[0060] S2. During the test, multi-source data is collected simultaneously, including the subject's motion image sequence, the pressure distribution time sequence data of the support surface, and the spatial posture data of the test aid.

[0061] Specifically, the visual acquisition module acquires the sequence of motion images of the subject; the mechanical perception module acquires the temporal data of the pressure distribution on the support surface; and the posture perception module acquires the spatial posture data of the testing aid.

[0062] S3, based on the multi-source data, identify the relative angle between the torso and lower limbs and the position of key joints in real time, detect the off-ground status or displacement of the supporting parts, and determine whether the test auxiliary device maintains the preset posture.

[0063] The supporting parts include the knees, feet, and hands, and the key joints include the knee joint and elbow joint.

[0064] Based on the sequence of motion images, the relative angle between the torso and lower limbs and the position of key joints are identified; based on the time sequence data of pressure distribution, the off-ground status or displacement of the supporting parts is detected; based on the spatial posture data, it is determined whether the test auxiliary device maintains a preset posture.

[0065] In the squat test, identifying the relative angle between the trunk and lower limbs includes calculating the difference between the sagittal tilt angle of the trunk and the sagittal tilt angle of the tibia.

[0066] Detecting heel lift-off status includes determining whether the pressure value in the heel area is lower than a set threshold and whether the duration exceeds a preset time.

[0067] In the hurdle test, determining whether the test aid maintains the preset posture includes judging the absolute value of the pitch angle output by the posture perception module, and judging the test result based on the absolute value of the pitch angle.

[0068] The detection of support displacement includes calculating the displacement distance of the center point of the support based on the trajectory of the pressure center of gravity, and judging the detection result based on the displacement distance of the center point of the support.

[0069] In the shoulder flexibility test, the subject holds a test aid device with an integrated posture perception module in each hand. The posture data from both sides of the posture perception module is combined with the hand position in the motion image sequence, and the distance between the two fists is calculated by the triangulation algorithm.

[0070] S4. Based on the above judgment results, match them with the preset FMS scoring rule library to generate quantitative scores and deviation location information.

[0071] S5 outputs an evaluation report containing quantitative scores and deviation location information after the test is completed.

[0072] Of course, during the testing process, when any judgment result deviates from the standard action tolerance range, a feedback mechanism is triggered in real time, including:

[0073] Correction instructions are output via the speech synthesis module;

[0074] Dynamic guide graphics are overlaid on the display interface, and the deviation areas are highlighted.

[0075] Example 2

[0076] like Figure 2-9 As shown, the present invention provides a portable intelligent testing device, which includes a host 100, a vision acquisition module 200, a mechanical sensing module, and a testing auxiliary instrument 400.

[0077] The host unit 100 is equipped with a display screen and a speaker. Before the test, a standard movement demonstration video can be played on the display screen, and voice explanations can be output synchronously through the speaker. During the test, a dynamic guidance video can be played on the display screen (e.g., a virtual horizontal line to guide the posture of the bar when hurdling), and voice instructions can be given to the subject in real time through the speaker (e.g., please keep the bar close to your head). After the test, the video of the subject's movements can be played back on the display screen (e.g., a slow-motion video showing deviation angles marked at the joints), and voice instructions can be played through the speaker to point out the deficiencies in the subject's movements.

[0078] In this embodiment, the visual acquisition module 200 is a camera mounted on the host 100 and / or a separate bracket. The visual acquisition module 200 is electrically connected to the host 100 and is used to sequence motion images and transmit the motion image sequences to the host 100. The host 100 then uses the motion image sequences transmitted from the visual acquisition module 200 to determine whether the subject's movements are standard.

[0079] The mechanical sensing module is electrically connected to the host 100. The mechanical sensing module acquires and transmits pressure distribution time-series data to the host 100. For example, during a squat test, it acquires mechanical interaction information between both feet and the support surface; during a hurdle test, it acquires pressure distribution time-series data between a single foot and the support surface; during a rotational stability test, it acquires pressure distribution time-series data between the feet, knees, and hands and the support surface. This pressure distribution time-series data includes at least one of pressure distribution, center of gravity shift, local ground-lift status, or displacement of the supporting foot 513, and the detection results are transmitted to the host 100. The host 100 then uses the mechanical interaction information transmitted from the mechanical sensing module to determine whether the subject's feet, knees, hands, and the support surface are properly aligned.

[0080] In this embodiment, the testing aid 400 is a testing rod with an internal posture sensing module 420. The testing rod includes a long rod used in squat, hurdle, and straight-line lunge tests, and a short rod used in shoulder flexibility tests. In this embodiment, the posture sensing module 420 is an inertial measurement unit (IMU). The posture sensing module 420 is electrically connected to the host 100. The posture sensing module 420 detects the spatial posture information of the testing aid 400 during the testing process and transmits the spatial posture data to the host 100. The host 100 then uses the data transmitted from the posture sensing module 420 to determine whether the testing aid 400 is level.

[0081] During operation, the host 100 plays a standard action demonstration video on the display screen before the test and outputs voice explanation through the speaker simultaneously. During the test, the host 100 integrates the action image sequence of the visual acquisition module 200, the pressure distribution time sequence data of the mechanical perception module, and the spatial posture data of the posture perception module 420, and guides the subject to adjust the action in real time through voice prompts and dynamic guidance graphics on the screen. After the test, the host 100 automatically judges the standardization of the action based on the multi-source data, generates a score result, and highlights the deviation parts or parameters in the playback screen, so as to achieve objective, efficient and repeatable functional action screening.

[0082] For example:

[0083] During the squat test, the visual acquisition module 200 acquires motion image information of the subject and transmits the acquired information to the host 100. The host 100 then uses the motion image information transmitted by the visual acquisition module 200 to determine the parallelism between the subject's torso and tibia and whether the knee goes past the toes. The biomechanical sensing module acquires biomechanical interaction information between the subject and the support surface during the test and transmits the acquired biomechanical interaction information to the host 100. The host 100 then uses the biomechanical interaction information transmitted by the biomechanical sensing module to determine whether the subject's heels are raised.

[0084] During the hurdle test, the posture sensing module 420 within the testing aid 400 detects the posture information of the testing aid and transmits the detected information to the host 100. The host 100 then uses the information transmitted from the posture sensing module 420 to determine whether the testing aid remains horizontal. The visual acquisition module 200 acquires motion image information of the subject and transmits the acquired motion image information to the host 100. The host 100 then uses the motion image information of the subject transmitted from the visual acquisition module 200 to determine whether the subject's body is swaying excessively. The mechanical sensing module acquires the mechanical interaction information between the subject and the support surface during the test and transmits the acquired mechanical interaction information to the host 100. The host 100 then uses the mechanical interaction information transmitted from the mechanical sensing module to determine whether the subject's supporting foot 513 has moved.

[0085] During the shoulder flexibility test, the subject holds a test aid 400 in each hand. The main unit 100 calculates and records the distance between the two fists based on the data from the posture perception module 420 in the two test aids 400 and the images captured by the vision acquisition module 200, thereby assessing the range of motion and bilateral symmetry of the shoulder.

[0086] Preferably, the main unit 100 is equipped with a portable handle and / or a dedicated storage bag.

[0087] The handle makes it easy to carry the whole machine by hand, while the dedicated storage bag can hold all components such as the main unit 100, the vision acquisition module 200, the testing auxiliary equipment 400, and the mechanical sensing module, enabling integrated carrying and rapid deployment in various scenarios such as gyms, rehabilitation centers, and outdoor training fields.

[0088] Example 3

[0089] like Figure 3 and Figure 4As shown, this embodiment optimizes the structure of the testing auxiliary device 400 based on the above embodiment. The testing auxiliary device 400 includes multiple coaxially arranged and detachably connected rods 410, at least one rod 410 is embedded with an attitude sensing module 420, and adjacent rods 410 are detachably coaxially connected through end connection structures. Specifically, in this embodiment, there are two rods 410, and each rod 410 is provided with an attitude sensing module 420.

[0090] This structure allows the test aid 400 to be flexibly assembled in different lengths according to different test items (e.g., a short bar is needed for shoulder flexibility, and a long bar is needed for squatting assistance). After use, it can be disassembled and stored, significantly improving portability and applicability. At the same time, it ensures that the posture sensing module 420 is always in the effective measurement position.

[0091] Example 4

[0092] like Figure 3 As shown, this embodiment further defines the specific form of the end connection structure based on the above embodiments. The end connection structure can be any one of a threaded connection structure, a snap-fit ​​connection structure, a magnetic connection structure, or a plug-in quick-installation structure.

[0093] All of the above connection methods can achieve rapid assembly and reliable coaxial positioning between rods 410. Among them, the threaded connection structure provides high stability, while the magnetic or plug-in structure facilitates one-handed operation. Users can choose the appropriate solution according to the usage scenario, taking into account both connection strength and ease of operation.

[0094] Specifically, in this embodiment, the end connection structure is a threaded connection structure, that is, one end of one rod 410 is provided with an external thread 411, and one end of the other rod 410 is provided with an internal thread hole 412 that is compatible with the external thread.

[0095] Example 5

[0096] like Figure 2 and Figure 8 As shown, this embodiment, based on the above embodiment, designs the biomechanical sensing module with functional partitions. The biomechanical sensing module includes a full-body support monitoring pad 310 and a foot positioning monitoring pad 320. The full-body support monitoring pad 310 is used to monitor the overall support status during squats, straight lunges, trunk stability push-ups, active straight leg raises, or rotational stability movements. The foot positioning monitoring pad 320 is used to monitor the support status of one foot during hurdle steps or shoulder flexibility tests.

[0097] By configuring partitions, the system can call up the corresponding sensing areas for actions such as standing on two feet and standing on one foot, avoiding interference from invalid areas and improving the accuracy and response speed of foot biomechanical state recognition.

[0098] Example 6

[0099] like Figure 8 As shown, this embodiment, based on the above embodiments, clarifies the structure of the sensing layer of the force sensing module. The force sensing module includes a force sensing layer 330, which is electrically connected to the host 100, and the force sensing layer 330 is at least one of a pressure sensor array, a flexible force-sensitive film, a piezoelectric sensing layer, an electronic fabric, or a distributed tactile sensing element.

[0100] All of the above materials are flexible, highly sensitive, and have spatial resolution capabilities. They can be laid inside the monitoring pad and output continuous pressure distribution signals when subjected to foot pressure, providing a high-fidelity mechanical interaction data foundation for the host 100.

[0101] Example 7

[0102] like Figures 5-7 As shown, this embodiment adds a hurdle frame 500 to support hurdle step testing, based on the above embodiment. The hurdle frame 500 includes two support frames 510 and a hurdle indicator 520 erected between the tops of the two support frames 510.

[0103] The support frame 510 is a telescopic or foldable structure with multi-level height adjustment. The hurdle indicator 520 provides the subject with a visual and spatial reference for the hurdle height during the hurdle test.

[0104] This design enables the device to fully cover the hurdle test in the seven FMS tests. The height adjustment mechanism, in conjunction with the relative sliding of the inner column 512 and the outer column 511, allows for stepless or graded adjustment of the overall height of the support frame 510, making it adaptable to subjects of different heights and ensuring standardized testing conditions. The folding structure ensures compact storage.

[0105] Example 8

[0106] like Figures 5-7 As shown, this embodiment refines the mechanical structure of the support frame 510 based on the above embodiment. The support frame 510 includes a central column, support legs 513, and an unfolding locking mechanism.

[0107] The central column includes an outer column 511, an inner column 512 coaxially slidably inserted into the outer column 511, and a height adjustment mechanism disposed between the outer column 511 and the inner column 512. The height adjustment mechanism is used to adjust the extension length of the inner column, thereby adjusting the height of the crossing indicator 520.

[0108] Support legs 513 are hinged to outer column 511. At least three support legs 513 are evenly arranged around the central column to provide a stable triangular / polygonal support base. An unfolding locking mechanism is provided between the support legs 513 and the central column, and is used to lock the support legs 513 when unfolded.

[0109] In this embodiment, the support foot 513 provides a stable triangular / polygonal support base, and the unfolding locking mechanism ensures rigid fixation after unfolding.

[0110] Example 9

[0111] like Figure 7 As shown, this embodiment refines the mechanical structure of the height adjustment mechanism based on the above embodiment. The height adjustment mechanism includes a nut 514 and a screw 515.

[0112] The nut 514 is disposed inside the inner column 512 and is slidably connected to the inner column 512 along the axial direction. The nut 514 is fixedly connected to the inner wall of the bottom end of the outer column 511 through the connecting shaft 516.

[0113] The screw 515 is coaxially inserted into the inner cylinder 512, and the screw 515 is rotatably connected to the inner cylinder 512. The screw 515 is also threadedly connected to the nut 514.

[0114] During operation, the nut 514 is limited by the connecting shaft 516 and cannot rotate, but can only move axially along the inner column 512. At the same time, it is limited by the outer column 511 and cannot move. Therefore, when the screw 515 is rotated, the interaction between the screw 515 and the nut 514 causes the inner column 512 to rise and fall relative to the outer column 511 through the screw 515, thereby achieving precise height adjustment. The structure is simple and has good self-locking performance.

[0115] Example 10

[0116] like Figures 5-6 As shown, this embodiment refines the mechanical structure of the unfolding locking mechanism based on the above embodiment. The unfolding locking mechanism includes a slider 531 that is slidably connected to the support leg 513 along its length direction, and a locking rod 532 with its first end hinged to the slider 531 and its second end hinged to the central column.

[0117] When the support foot 513 extends outward, the slider 531 slides along the support foot 513, causing the locking rod 532 to rotate and eventually abut against the central column to form a rigid triangular support, thereby achieving automatic locking; when retracting, it can be unlocked by pushing in the opposite direction, which is simple to operate and reliable in locking.

[0118] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of the invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

[0119] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
