Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of motion inspection, in particular to a functional motion screening device. Background Art
[0002] In today's society, people are paying more and more attention to the improvement of physical health and athletic ability. Functional Movement Screening (FMS) is a tool used to assess individual functional movement ability. By examining and evaluating a series of body movements, it can help identify potential sports injury risks and imbalance problems. Currently, the functional movement screening uses a matching FMS kit including a long horizontal bar, two short vertical bars, a movement screening board, and an elastic band to test 7 basic functional movements (including squats, hurdle steps, straight lunges, shoulder flexibility, active straight leg raises, trunk stability push-ups, and trunk rotation stability). At present, the scoring of functional movements mainly relies on the observer's visual inspection to complete the quantitative scoring, that is, it is necessary to rely on the observer's experience and subjective judgment to score, and it is impossible to achieve objective and accurate detection. In addition, different observers will have deviations, and the same observer will also have deviations due to the observation angle. Utility Model Content

DETAILED DESCRIPTION
[0029] The present application will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or descriptions, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In the description of this application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0030] Please refer to Figures 1 to 4 The embodiment of the present application provides a functional action screening device 10, which may include a first group of sensors 11, a second group of sensors 12, a third group of sensors 13, a controller 14, and a prompt module 15. The functional action screening device 10 may also include a horizontal bar 21, two vertical bars, and a test board 24, wherein the two vertical bars may be respectively referred to as a first vertical bar 22 and a second vertical bar 23.
[0031] In this embodiment, the first group of sensors 11 is used for the person being measured to wear on the key body surface parts of the human body, and is used to collect the first posture signal of the key body surface parts of the human body. The first group of sensors 11 may include multiple gyroscopes for collecting posture signals (to facilitate the distinction from the gyroscopes of the second group of sensors 12 described below, the gyroscopes in the first group of sensors 11 are referred to as first gyroscopes 111, and the gyroscopes in the second group of sensors 12 are referred to as second gyroscopes 121). Key body surface parts of the human body may include but are not limited to shoulders, elbows, wrists, mid-thighs, knee joints, ankle joints and other parts. Please refer to Figure 3Each key body surface part of the measured person is equipped with a first gyroscope 111 for detecting the posture signal of each key body surface part.
[0032] The second group of sensors 12 are arranged at key positions of the crossbar 21, and are used to collect second posture signals of the key positions of the crossbar 21. In this embodiment, the second group of sensors 12 may include a plurality of gyroscopes (i.e., second gyroscopes 121) for collecting posture signals, and the key positions of the crossbar 21 may include both ends and the middle of the crossbar 21.
[0033] As an example, please refer again to Figure 3 The second sensor group 12 may include three second gyroscopes 121 , which are respectively arranged at both ends and the middle of the cross bar 21 .
[0034] The third group of sensors 13 are arranged at designated positions of the two vertical poles, and are used to detect the shielding signal between the designated positions of the two vertical poles. The third group of sensors 13 may include one or more groups of laser transceivers for detecting whether there is an obstruction, and each group of laser transceivers includes a laser transmitter 131 and a laser receiver 132. The designated positions of the vertical poles may be flexibly determined according to actual conditions, and may be the ends or the pole bodies of the vertical poles.
[0035] As an example, see Figure 4 The third group of sensors 13 includes a laser transmitter 131 disposed on the first vertical rod 22 and a laser receiver 132 disposed on the second vertical rod 23 .
[0036] Please refer again Figure 4 In this embodiment, the first vertical rod 22 and the second vertical rod 23 are installed on the test board 24 to cooperate in detecting the action of "hurdle step". The laser transmitter 131 and the laser receiver 132 cooperate with each other to detect whether the laser emitted by the laser transmitter 131 is blocked by the legs when the person being tested completes the "hurdle step".
[0037] Understandably, when the third group of sensors 13 is in operation, the laser emitted by the laser emitter 131 can be normally irradiated on the laser receiver 132. If the laser receiver 132 does not receive the laser emitted by the laser emitter 131, a first level signal indicating that there is an obstruction between the designated parts of the two vertical poles will be generated; if the laser receiver 132 continues to receive the laser emitted by the laser emitter 131, that is, the received laser has not been interrupted, the laser receiver 132 will generate a second level signal indicating that there is no obstruction between the designated parts of the two vertical poles. The obstruction signal may include a first level signal and a second level signal.
[0038] As an example, the first level signal may be a high level signal, and the second level signal may be a low level signal.
[0039] In this embodiment, the first sensor group 11, the second sensor group 12, the third sensor group 13 and the prompt module 15 are all connected to the controller 14 by signals. It can be understood that the first sensor group 11, the second sensor group 12 and the third sensor group 13 can send the generated sensing signals to the controller 14. The signal connection can refer to a wireless communication connection or a wired communication connection.
[0040] For example, the prompt module 15 is electrically connected to the controller 14 through a physical line. The first sensor group 11, the second sensor group 12, and the third sensor group 13 can be electrically connected to the controller 14 through a physical line. In other embodiments, each sensor group can be provided with a wireless transmission module (for example, a Bluetooth transmission module), and the controller 14 is provided with a wireless receiving module (for example, a Bluetooth receiving module), and the first sensor group 11, the second sensor group 12, and the third sensor group 13 can be connected to the controller 14 signal through a wireless network.
[0041] In this embodiment, the horizontal bar 21, the two vertical bars and the test board 24 are used for the person being tested to complete corresponding functional movements, which may include 7 movements corresponding to the functional movement screening (FMS), namely squats, hurdle steps, straight lunges, shoulder flexibility, active straight leg raises, trunk stability push-ups and trunk rotation stability.
[0042] In this embodiment, a second group of sensors 12 are arranged on the crossbar 21 to sense the position and angle changes of the crossbar 21, so as to detect whether the crossbar 21 moves or deflects during the "squat" and "hurdle step" movements. The third group of sensors 13 arranged on the two vertical bars can detect whether the legs of the person being measured block the laser emitted by the laser emitter 131 when the person being measured is doing the "hurdle step" movement. The laser line generated by the third group of sensors 13 serves as an obstacle that the person being measured needs to cross.
[0043] In other embodiments, the two vertical poles may be connected by an elastic band, which is arranged parallel to the laser line and located above the laser line. The elastic band may serve as an obstacle that the person being measured needs to cross.
[0044] The scoring criteria for each FMS sub-item are 3 points, 2 points, 1 point, and 0 points. One sub-item is a functional action. The scoring criteria for each functional action are common knowledge, for example:
[0045] ① To complete the full-score squat action (3 points), the testee needs to hold the horizontal bar 21 above the head with both hands and directly above the feet, with the upper body straight, the thighs below the horizontal plane, and the knee joints directly above the feet;
[0046] ② To complete the full-score hurdle step action (3 points), the person being tested needs to hold the horizontal bar 21 behind the neck with both hands and keep it parallel to the hurdle frame during the action, keep the supporting leg on the test board 24 with the hip, knee and ankle straight, and move the waist slightly;
[0047] ③ Complete the full-score straight lunge squat action (3 points), which requires the testee to stand on the test board 24 with both hands holding the horizontal bar 21 behind the torso, and the torso does not move at all during the action, the feet remain on the test board 24, and the heel of the front foot and the knee of the back leg touch the test board 24;
[0048] ④Complete the full score of active straight leg raising (3 points), which requires the vertical line of the lateral ankle to fall between the middle of the thigh and the anterior superior iliac spine, and the lower limb on the non-moving side to maintain a neutral position;
[0049] ⑤ Complete full-mark trunk stability push-ups (3 points), requiring the waist to not shake during the movement and the lumbar spine to remain in a naturally straight position;
[0050] ⑥ To complete the full score of the trunk rotation stability test (3 points), it is necessary to extend the shoulder, hip and knee joints on the same side. The raised elbow, hand and knee must be kept in the same plane as the edge of the test board 24. At the same time, the trunk should be kept in a horizontal plane parallel to the test board 24. The lumbar spine should be kept naturally straight throughout the process.
[0051] As an example, the test scenario of the subject doing a "squat" is as follows Figure 3 As shown, in Figure 3 In the test, the subject holds the horizontal bar 21 with both hands and does a squat. Figure 4 As shown, in Figure 4 In the test, the person being tested carries the horizontal bar 21 on his shoulders, holds the horizontal bar 21 on his shoulders with both hands, and performs a hurdle step action.
[0052] During the test, after the person being tested wears the first set of sensors 11 and completes the designated functional actions according to the corresponding requirements, the controller 14 can control the prompt module 15 to output an evaluation result representing that the person being tested has completed the designated functional actions. The evaluation result can be a result indicating whether the action is qualified, or a score for completing the action, which can be flexibly determined according to actual conditions. The designated functional actions can include any one of squats, hurdle steps, straight lunges, shoulder flexibility, active straight leg raises, trunk stability push-ups, and trunk rotation stability.
[0053] In this embodiment, during the test of the person being tested, the controller 14 can determine the scores corresponding to the first posture signal, the second posture signal and the occlusion signal according to a pre-calibrated scoring table corresponding to the specified functional action as an evaluation result, wherein the scoring table records the mapping relationship between the posture signals collected by the first group of sensors 11, the posture signals collected by the second group of sensors 12 and the occlusion signals collected by the third group of sensors 13 and the scores.
[0054] Understandably, engineers pre-calibrate a corresponding scoring table for each functional action, and the scoring table can be pre-stored on the controller 14. Among them, the first posture signal and the second posture signal can be converted into position coordinate data between each acquisition point, and the conversion method is conventional, which will not be repeated here. Based on the range of the position coordinates of the corresponding acquisition points when the person under test completes a single functional action under different scores, a scoring table can be created. That is, each scoring table records the mapping relationship between the range of sensor signals of each group of sensors during the functional action completed by the person under test and the corresponding scores. Among them, the acquisition point is the location where the gyroscope is installed.
[0055] During the test, the controller 14 can look up the table to obtain the score based on the sensor signals obtained from the first group of sensors 11, the second group of sensors 12, and the third group of sensors 13. Before the test, the prompt module 15 can send out guidance information of the name of the functional action that the test person is about to complete. After sending the guidance information, the controller 14 can call the score table corresponding to the functional action to score the completion of the kinetic action.
[0056] In this embodiment, the prompt module 15 may include a speaker and / or a prompt light for issuing an evaluation result representing whether the person being tested has completed a specified functional action. Understandably, the speaker may issue a voice prompt indicating that the action is qualified or unqualified under the control of the controller 14. The prompt light may issue a light prompt indicating that the action is qualified or unqualified under the control of the controller 14. For example, the prompt light includes a lamp bead that can emit multiple colors, and a green light is on when the action is qualified, and a red light is on when the action is unqualified.
[0057] When the evaluation result is a more refined score, the speaker can emit a voice with a corresponding score under the control of the controller 14. The voice chip of the controller 14 is pre-burned with voice content with a corresponding score.
[0058] When the evaluation result is a more refined score, the warning light may include multiple lamp beads, and the controller 14 may control the corresponding number of lamp beads to light up according to the obtained score. For example, the scoring criteria for each sub-item of FMS are 3 points, 2 points, 1 point, and 0 points. The warning light may include 3 lamp beads, and each time a lamp bead is lit, the score is increased by 1; if all three lamp beads are not lit, it means 0 points; if all three lamp beads are lit, it means that the score for completing the corresponding functional action is 3 points.
[0059] In other implementations, the prompt module 15 may be a display screen with a voice playback function, and the display screen may output a corresponding score value.
[0060] Please refer to Figure 2 As an optional embodiment, the functional action screening device 10 may further include a comparator 16. The first group of sensors 11, the second group of sensors 12 and the third group of sensors 13 are all connected to the controller 14 signal through the comparator 16. During the test, the comparator 16 is used to compare the first posture signal, the second posture signal and the occlusion signal with the preset signal representing the qualified action. The preset signal can be flexibly set according to the posture signal and the occlusion signal when each functional action is completed qualifiedly.
[0061] If any one of the first posture signal, the second posture signal and the occlusion signal is different from the corresponding preset signal, the comparator 16 outputs a first level signal representing an unqualified action to the controller 14, and the controller 14 controls the prompt module 15 to output an evaluation result representing an unqualified action based on the first level signal.
[0062] If the first pose signal, the second pose signal and the occlusion signal are all the same as the corresponding preset signals, the comparator 16 outputs a second level signal indicating that the action is qualified to the controller 14, and the controller 14 controls the prompt module 15 to output an evaluation result indicating that the action is qualified based on the second level signal. The first level signal may be a high level signal, and the second level signal may be a low level signal.
[0063] It should be noted that the signal processing of the sensor involved in the technical solution of the present application is a prior art and does not involve improvements to the computer program.
[0064] In this embodiment, the controller can be an integrated circuit chip with signal processing capability. The controller can be a central processing unit (CPU), a digital signal processor (DSP), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a single chip microcomputer (such as STM32 series chips), a microprocessor, etc.
[0065] The above description is only an embodiment of the present application and is not intended to limit the scope of protection of the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the scope of protection of the present application.
