Description

Technical Field

[0001] The invention relates to the technical field of massage training, and in particular provides a massage technique training system. Background Art

[0002] Tuina, also known as "massage" and "pressing the legs", is a traditional Chinese medicine external treatment method; Tuina techniques are the key to the clinical treatment of Tuina. Tuina training mainly involves: "technique" (force method and strength), "time" (massage duration, frequency and speed), "space" (massage site and range), "movement" (posture and manual movement); the above four aspects are important factors affecting the clinical efficacy of Tuina and are the focus of Tuina teaching. In the process of Tuina training, teachers can judge whether students have errors in the three aspects of "time, space and movement" through observation, so as to correct the errors and improve the students' operation level. Tuina is very physically demanding, so in terms of "technique", many labor-saving techniques need to be mastered in order to achieve long-term Tuina work.

[0003] However, in terms of "technique", it is difficult for teachers to make accurate judgments through observation, especially when students are prone to incorrect force generation despite correct posture. In this case, because the student's posture is correct, it is difficult for the teacher to observe whether the student's force generation method is correct. Instead, the teacher can only judge whether the student's force generation method is correct by whether the student is easily fatigued. For example, if the student is easily fatigued, it means that the force generation method is incorrect. However, whether the student is easily fatigued cannot accurately determine which specific massage movements of the student are inaccurate in force generation, and the teacher cannot provide effective guidance, resulting in the difficulty of teaching the force generation method in massage training. Summary of the invention

[0004] The present invention provides a massage technique training system, which is used to solve the problem that during training, a teacher cannot accurately judge whether a trainee's force-generating method is correct and cannot effectively teach the trainee on the force-generating method.

[0005] The technical solution of the present invention is as follows:

[0006] A massage technique training system includes a first pressure sensor, a motion capture mechanism, an electromyographic acquisition mechanism and a force model; wherein:

[0007] The pressure sensor is used to detect the pressure applied to the force model during the massage process.

[0008] The motion capture mechanism is used to capture the trajectory of body movements.

[0009] The myoelectric acquisition mechanism is used to collect the myoelectric signals of the muscles and convert the myoelectric signals into muscle force parameters;

[0010] It also includes a controller, which stores standard data of massage techniques, the standard data including standard limb movement trajectory, standard pressure and standard muscle force parameters, the pressure sensor, motion capture mechanism and electromyography acquisition mechanism are electrically connected to the controller respectively, the controller compares the captured limb movement trajectory with the standard limb movement trajectory, and determines whether the limb movement trajectory is accurate; the controller makes the standard pressure correspond to the pressure detected by the pressure sensor, and compares the pressure detected during the massage process with the standard pressure; the controller makes the standard muscle force parameters correspond to the muscle force parameters detected by the electromyography acquisition mechanism, and compares the muscle force parameters during the massage process with the standard muscle force parameters.

[0011] In this solution, the pressure sensor can detect whether the pressure on the force model during the massage process is sufficient. The motion capture mechanism can capture the trajectory of limb movements. Through the captured limb movement trajectory, it can be judged whether the posture, limb movement, movement amplitude and movement frequency during massage are accurate. The electromyographic acquisition mechanism can collect the electromyographic signals of the muscles and convert the electromyographic signals into muscle force parameters. By comparing the collected muscle force parameters with the standard muscle force parameters, it can be judged whether the force method is correct. If the measured integral electromyographic value is greater than the standard integral electromyographic value, it means that the force method is not labor-saving enough; if the measured muscle contribution rate is greater than the standard muscle contribution rate, it means that the force-generating muscle is incorrect; if the measured discharge time is different from the standard discharge time, it means that the force order of each muscle participating in the action is incorrect; if the muscle synergistic contraction rate is lower than the standard muscle synergistic contraction rate, it means that the synergy of the muscles participating in the action is poor and the action efficiency is not high. The teacher can accurately judge whether the student's force method is correct based on the size of the muscle force parameters, so that the teacher can judge the student's force method through quantitative data and accurately guide the student's force method.

[0012] Preferably, the electromyographic acquisition mechanism includes a plurality of surface electrodes, each surface electrode being used to fixedly acquire the electromyographic signals of different muscles.

[0013] In this solution, the surface electrodes only need to be attached to the skin surface to collect the electromyographic signals of the corresponding muscles, which is simple and quick to operate. In addition, multiple surface electrodes can be set to collect the electromyographic signals of multiple muscles respectively. By combining the force of each muscle, the wrong position of force can be judged more accurately, which is convenient for teachers to provide precise guidance.

[0014] In order to solve the problem of the surface electrodes being misplaced, the force model is provided with reference points, and the reference points correspond to the placement positions of the surface electrodes.

[0015] In this scheme, when it is necessary to attach surface electrodes to the muscles, the surface electrodes can be attached by referring to the position of the control points on the force model. With the control points as position references, trainees can attach the surface electrodes to more accurate positions, thereby accurately collecting the electromyographic signals of the corresponding muscles.

[0016] In this scheme, the sticking scheme (position, number, etc.) of the surface electrodes varies according to different massage operation actions.

[0017] When multiple surface electrodes are provided, each surface electrode is used to detect the electromyographic signals of different muscles. To solve the problem that the electromyographic signals detected by each surface electrode cannot be distinguished, each surface electrode and each control point are respectively provided with a label, and the surface electrode corresponds to only one control point.

[0018] In this solution, since one surface electrode corresponds to only one reference point, the surface electrode will only be attached to the same position when in use, and will only collect the electromyographic signal of one position. Therefore, it is only necessary to determine which surface electrode the electromyographic force parameter corresponds to, and then it is known which muscle part the muscle force parameter corresponds to, which can solve the problem of muscle force parameter being unable to be identified.

[0019] Preferably, the positions of the control points correspond to the correct muscle positions and incorrect muscle positions for exerting force during the massage action.

[0020] In this solution, the position of the control point corresponds to the position of the correct muscle, which can detect whether the muscle that should exert force is exerting force and whether the force is too large; and the position of the control point also corresponds to the position of the wrong muscle, which can detect whether the student is exerting force in the wrong way, which is convenient for the teacher to guide. It should be noted that the wrong muscle position refers to one or several muscle positions that are easy to exert force incorrectly based on experience statistics.

[0021] Preferably, the electromyographic acquisition mechanism converts the signals collected by the surface electrodes into muscle force parameters and sends them to the controller. The controller counts the signal sequence of each surface electrode to determine the force sequence, size, contribution and degree of coordination of different muscles in the massage action.

[0022] In this solution, the force generation sequence of each muscle is determined by the force generation parameters of each muscle. It can be determined whether the force generation sequence of each muscle is correct, thereby judging whether the student's force generation method is correct, so that the teacher can provide accurate guidance.

[0023] In order to solve the problem that the pressure sensor is difficult to connect to the human body, a detection glove is also included. The pressure sensor is arranged on the detection glove, and the pressure sensor is fixed to the human body through the detection glove.

[0024] In this solution, the pressure sensor is set on the detection glove. When training is needed, you only need to put on the detection glove to fix the relative position of the pressure sensor and the hand. The whole process is efficient and convenient. After the training is completed, the pressure sensor can be separated from the hand by taking off the glove. The operation is simple and efficient.

[0025] Preferably, the fingertips, palms and backs of the detection gloves are respectively provided with pressure sensors.

[0026] In order to solve the problem that students cannot intuitively feel whether the pressure applied to the force model is sufficient during the massage process, the gloves are provided with an indicator light, which is electrically connected to the controller and is used to display whether the pressure detected by the pressure sensor reaches the standard pressure.

[0027] In this solution, since the indicator light is provided on the detection glove, the trainee can judge whether the pressure is accurate by observing the state of the indicator light during the massage process.

[0028] Preferably, the motion capture mechanism captures the motion trajectory of the torso and arms.

[0029] In this solution, during the massage process, the rational use of the body weight of the trunk can achieve the effect of saving effort. Therefore, the movement trajectory of the trunk is captured, and the range of motion of the trunk is used to determine whether the trainee has used the weight of the trunk, thereby correcting the trainee's massage movements.

[0030] Beneficial effects of the present invention:

[0031] The present invention collects the student's pressing pressure on the force model, limb movement trajectory and muscle force, respectively, and can judge the student's force size, posture, movement trajectory and movement frequency. In particular, the student's force method can be corrected through electromyographic signals, solving the problem that it is difficult to accurately teach the student's force method. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to more clearly illustrate the technical solution of the present invention, the drawings required for describing the embodiments are briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0033] Figure 1 It is a schematic diagram of the system structure of the present invention. DETAILED DESCRIPTION

[0034] In conjunction with the accompanying drawings, the technical solution of the present invention is clearly and completely described through specific implementation methods of the embodiments of the present invention.

[0035] like Figure 1As shown, this embodiment provides a massage technique training system, including an electromyographic acquisition mechanism for collecting electromyographic signals of trainees, the electromyographic acquisition mechanism is used to collect electromyographic signals and convert the electromyographic signals into muscle force parameters. The electromyographic acquisition mechanism is configured with surface electrodes to collect electromyographic signals. The surface electrodes are attached to the surface of the skin, so as to collect electromyographic signals of the muscles under the skin. There are multiple surface electrodes, each of which is attached to different positions of the skin, so as to collect electromyographic signals of different muscles. It should be noted that the muscles corresponding to the surface electrodes are the muscles that will obviously exert force during the massage process.

[0036] The training system also includes a force model, on which the trainee practices massage movements. A reference point is set on the force model, and the position of the reference point corresponds to the position of the muscle, which is used as a reference for the position of the surface electrode. The trainee can observe the position of the reference point when attaching the surface electrode to ensure that the surface electrode can be attached to the correct position.

[0037] The training system also includes a pressure sensor for detecting the massage pressure of the trainee, and the pressure sensor is arranged on the detection glove. During training, after the trainee wears the detection glove, the pressure sensor located in the detection glove can detect the pressure applied by the trainee's hand on the force model, and the pressure data applied by the trainee can be obtained. The pressure data obtained can be used to determine whether the trainee's force is sufficient.

[0038] The palm, fingers, back of the hand and hypothenar of the detection glove are respectively provided with pressure sensors, which are used to detect whether the pressure of various parts of the hand is sufficient during different massage movements.

[0039] Alternatively, the detection gloves can be long gloves that can include both the palm and elbow of the trainee. In this case, a pressure sensor can also be set at the elbow position to detect whether the elbow force is sufficient during the action that requires elbow massage.

[0040] An indicator light can be set on the back of the hand of the detection glove, and the trainee can observe whether the applied pressure is accurate through the indicator light. For example, the indicator light has three colors, and the indicator light is electrically connected to the controller. The controller controls the color change of the indicator light according to the pressure signal. When the pressure applied by the trainee is greater than the standard pressure, the indicator light is red, when the pressure applied by the trainee is less than the standard pressure, the indicator light is yellow, and when the pressure applied by the trainee is within the standard pressure range, the indicator light is green. The trainee can judge whether the applied force is accurate through the indicator light. Setting the indicator light on the back of the hand of the detection glove is convenient for the trainee to observe. During the massage process, the trainee will basically lower his head to observe the massage position, and the back of the hand will always be in the field of vision, so the trainee can always observe the indicator light and adjust the force according to the indicator light. If the pressure information is displayed in other positions, the trainee needs to keep turning his head to view the pressure data, and turning his head will cause the trainee's torso angle to change, resulting in inaccurate movements of the trainee. Therefore, making the indicator light always within the trainee's field of vision can ensure that the trainee can judge whether the force is sufficient while maintaining the correct posture.

[0041] The training system also includes a motion capture mechanism for capturing the trajectory of body movements, such as the movement trajectory of arms and torso. Through the captured movement trajectory, it can be observed whether the amplitude and frequency of the massage action are accurate.

[0042] The above signals can be compared by the controller. For example, the controller is electrically connected to the pressure sensor, motion capture mechanism and electromyographic acquisition mechanism, and the teacher demonstrates the correct massage action. The pressure sensor, motion capture mechanism and electromyographic acquisition mechanism transmit the corresponding data of the teacher's massage action to the controller, and the controller uses the data as standard data. The standard data includes the standard pressure, standard limb movement trajectory and standard muscle force parameters in the corresponding massage action, among which the standard limb movement trajectory refers to the limb movement amplitude and frequency.

[0043] When students are training, the pressure sensor will detect the pressure data applied by the students. The controller will compare the pressure data of the students with the standard pressure to determine whether the pressure data of the students is within a certain range of the standard pressure. If the pressure data of the students is within a certain range of the standard pressure, it means that the students have exerted enough force in the massage action.

[0044] The student data captured by the motion capture mechanism will also be compared with the standard body movement trajectory to determine whether the student's movement amplitude and movement frequency are standard. Whether the movement amplitude is standard can be determined by the body angle. For example, the teacher demonstrates that the arm angle is within the range of 30-60°. If the student's arm angle exceeds this range during the massage, it means that the student's arm movement amplitude is inaccurate. Similarly, if the student's arm angle movement range is 40-50°, it also means that the student's arm movement amplitude is inaccurate.

[0045] The electromyographic signals collected by the electromyographic acquisition mechanism are converted into muscle force parameters. The controller compares the trainee's muscle force parameters with the standard muscle force parameters to determine whether the trainee's force method is accurate.

[0046] It should be noted that the massage action is a continuous force action, and the pressure sensor will continuously detect the pressure. The massage action is also a continuous cycle action, and the pressure during the massage process changes cyclically. If time is used as the horizontal coordinate and the pressure data is used as the vertical coordinate, a continuously circulating line graph will be obtained in the coordinate graph formed by time and pressure data. The action frequency can also be determined by the cycle period of the line graph. According to the line graph, it can also be determined whether the change in the force applied in the massage action is accurate. For example, a massage action requires a gradual increase in pressure, and the pressure applied by the student in the massage action remains unchanged. The pressure data can also be used to determine whether the change in the student's force is accurate.

[0047] Similarly, the electromyographic signals collected by the electromyographic acquisition mechanism are also continuous. For example, in a continuous forward push, the muscles that exert force continue to exert force, so the electromyographic acquisition mechanism can continuously collect electromyographic signals. However, as the massage action progresses, other muscles will need to exert force after the limb angle changes. At this time, the electromyographic acquisition mechanism can also collect the force size, sequence and contribution of each muscle, as well as the force synergy of each muscle, to determine whether the student's action is accurate.

[0048] The muscle force parameters specifically include the integrated EMG value, muscle contribution rate, discharge time and muscle co-contraction rate. The integrated EMG value can reflect the size of muscle force, and the corresponding muscle force can be compared to determine whether the student's force is accurate. The muscle contribution rate reflects the contribution of the muscle in a specific action. Massage is a combination of many muscles. If the muscle contribution rate of a muscle is higher than the standard range, it means that the student has made a wrong choice of muscle in the massage. The discharge time can reflect the order in which each muscle participates in the force in an action; for example, in the massage operation, it is required to "drive the forearm with the upper arm", which can be judged by the discharge time of the upper arm and forearm muscles. The muscle co-contraction rate reflects the contraction synergy of each muscle in a specific action, which can reflect the efficiency of the massage action and determine whether each muscle has formed a coordination. By quantitatively monitoring the muscle force parameters, the problem of guiding the force method in massage teaching can be effectively solved, and the problem of "similar in form but not in spirit" in the massage operation of students can be effectively corrected.

[0049] It should be noted that the electromyography acquisition mechanism does not need to collect the electromyography conditions of all muscles, but only needs to collect the electromyography signals of several muscles that mainly exert force.

[0050] In an optional implementation, based on the common incorrect force-generating methods of students, the muscles corresponding to these incorrect force-generating methods can be monitored through muscle force parameters, so as to quickly correct the students, improve the correction efficiency, and improve the teaching quality.

[0051] The controller can also be equipped with a display to show the comparison between each data and the standard data. Both the teacher and the students can directly observe which aspects of the massage movements are inaccurate through the display.

[0052] If a display is configured, the motion capture mechanism can directly display the captured motion graphics through the display, and the pressure detected by the pressure sensor and the muscle force parameters collected by the electromyographic acquisition mechanism can be displayed through coordinate graphs respectively. The signals transmitted by different pressure sensors can be distinguished by lines of different colors, and the muscle force parameters corresponding to different muscles can also be distinguished by lines of different colors. In other words, on the interface of the display, one area displays the image of the limb movement trajectory captured by the motion capture mechanism, one area displays the coordinate graph of the pressure and time corresponding to the pressure sensor, and the last area displays the coordinate graph of the muscle force parameters and time. In each area, the data from the students and the standard data stored in the controller are displayed respectively, which is convenient for teachers and students to observe and compare.

[0053] In order to facilitate the teacher to observe the information of all students, the controller receives the information of multiple students at the same time. For example, the pressure sensor, motion capture mechanism and electromyography acquisition mechanism used to detect a student are used as an information acquisition unit. The controller can be electrically connected to multiple information acquisition units at the same time. The teacher can observe the data information of each student collected by the information acquisition unit through the display and observe whether the massage movements of each student are accurate.
