Description

Technical Field

[0001] The present invention relates to the field of muscle function assessment based on precise measurement of perioral muscle strength, and in particular to a perioral muscle strength rhythmic training assessment device and method. Background Art

[0002] Existing perioral muscle training programs include lip pursing, lip flicking, tongue lifting, tongue protrusion, and tongue flicking, which can be roughly divided into rhythmic (elastic) training (lip flicking, tongue flicking) and continuous training (lip pursing, tongue lifting, tongue protrusion).

[0003] Existing rhythmic (elastic) exercises for perioral muscle strength training lack unified standards for duration, frequency, and intensity, making the exercises repetitive and boring. There are no appropriate quantitative evaluation methods or standards for perioral muscle strength, making it impossible to accurately predict the effectiveness of muscle function training. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the present invention provides a perioral muscle strength rhythmic training evaluation device and method, which can automatically and accurately evaluate perioral muscle function training.

[0005] The technical solution adopted by the present invention to achieve the above-mentioned purpose is:

[0006] A perioral muscle strength rhythmic training assessment method comprises the following steps:

[0007] 1) Using a thin film pressure sensor to collect the resistance value signal of the perioral muscle force during training;

[0008] 2) Preprocessing the resistance value signal to obtain perioral muscle strength training information for a single action;

[0009] 3) Calculate the effectiveness of individual training movements;

[0010] 4) Determine whether the training time has reached the total training time. If so, proceed to step 5). Otherwise, repeat steps 1) to 3).

[0011] 5) Comprehensively evaluate the training movements during the entire training process and output the evaluation score of this training.

[0012] After the effectiveness of a single training action is obtained, a graphical output is provided showing the comparison between the single training action and the standard template.

[0013] The step 2) comprises the following steps:

[0014] 2.1) Convert the resistance value signal into a voltage value signal;

[0015] 2.2) Determine whether a training exercise is effective based on whether the pressure value and duration of the exercise are within the specified standard range;

[0016] 2.3) All ineffective movements are removed, and the pressure value and duration of effective movements are used as the perioral muscle strength training information of a single movement.

[0017] The step 3) is specifically as follows:

[0018] Assume that the height H of the standard template represents the pressure value, and the width W represents the effective time of the action. The actual pressure curve of the test is: in is the jth pressure sample of the i-th training action, j∈[1,J], J represents the number of samples in a single training action, then the difference between the actual detection pressure of a single sampling point and the template pressure is for:

[0019]

[0020] The standard template is used as a sliding window, with the number of sampling steps as the step size, and a single training action generates an effective degree sequence by sliding the standard template The first effective degree of the i-th training action is for:

[0021]

[0022] When the step size is n, the nth effective degree for:

[0023]

[0024] And so on, until W+n>J,

[0025] The generated effective degree sequence Take the minimum value to get the effectiveness A of the i-th training action (i) .

[0026] The step 5) is specifically as follows:

[0027] For all the effectiveness of the whole training process A (i) Sort from small to large to form a new sequence A (j) , calculate the effectiveness of the top N% of the rankings to obtain the evaluation score of the training effect of the entire training process. The evaluation score Score is:

[0028]

[0029] Among them, S is the effectiveness of all A in the entire training process(i) The number of, N is the set threshold, Score∈[0,100].

[0030] After obtaining the evaluation score of this training, the historical change curve of the perioral muscle rhythmic training is output in combination with the historical data of the trainee.

[0031] A perioral muscle strength rhythmic training and evaluation device, comprising:

[0032] Thin film pressure sensor, used to collect resistance value signals of perioral muscle strength during training;

[0033] A signal acquisition module, used for converting resistance value signals into voltage value signals;

[0034] The training action extraction module is used to detect and record the voltage value signal representing the training action after the end of a single training action.

[0035] A data analysis module is used to analyze the effectiveness of a single training action based on voltage value signals;

[0036] The comprehensive evaluation output module is used to comprehensively evaluate the training movements in the entire training process after a set of training movements is completed, and output the evaluation score of this training.

[0037] The thin film pressure sensor and the signal acquisition module transmit data wirelessly.

[0038] The present invention has the following beneficial effects and advantages:

[0039] 1. During perioral muscle training, accurate digital quantification of perioral muscle strength is provided, making it convenient for trainees to self-check changes in perioral muscle strength;

[0040] 2. Through voice prompts, formulate training time and movement frequency standards for the rhythmic (elastic) strength of the perioral muscles, and standardize and unify the perioral muscle training process.

[0041] 3. Manual interpretation of perioral muscle strength training results is very time-consuming and labor-intensive. The present invention uses automated analysis methods to evaluate each training action in real time and output the overall training effectiveness results.

[0042] 4. Real-time visual feedback allows trainees to intuitively understand the training situation, which is conducive to the correct guidance of trainees' movements; BRIEF DESCRIPTION OF THE DRAWINGS

[0047] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0048] Figure 1 This is a schematic diagram of the system for automatic evaluation of perioral muscle rhythmic (elastic) training of the present invention. The trainee places multiple thin film sensors at corresponding positions in the mouth to detect lip muscle strength and tongue muscle strength, collect data and complete transmission, and can provide voice prompts to the trainee based on instructions issued by the trainee or trainer. The system includes: a signal acquisition module 1, a training action extraction module 2, a data analysis module 3, and a comprehensive evaluation output module 4.

[0049] Signal acquisition module 1 uses sampling technology to achieve digital and synchronous sampling of lip and tongue muscle force. Before use, a calibration experiment is performed to calibrate the relationship between the sensor and voltage changes. The sampling rate is determined by the hardware setting frequency, and digital information about the trainee's perioral muscle force is obtained during the training period.

[0050] Training action extraction module 2 is used to detect the pulse signal generated by the training action. The system prompts the start and end of the action, which facilitates the trainee to carry out perioral muscle strength rhythmic training with a fixed training frequency and holding time. After the completion of a single training action, the training action digital signal is extracted;

[0051] Data analysis module 3 is used to analyze the effectiveness of a single training action. The ideal training action digital pulse signal is similar to a rectangular wave. The trainee's single training action signal is compared with the ideal training action signal to analyze the effectiveness of the current action.

[0052] Comprehensive evaluation output module 4: After the trainee completes a set of training movements, the training movements in the entire training process are comprehensively evaluated, and the objective evaluation score of this training and the analysis of the individual's training history changes are output;

[0053] Thin film sensor 5, the thin film pressure sensor is a circular thin film of flexible material with a diameter of about 7mm and a thickness of about 0.4mm. The pressure sensing range is 2g to 100g. The measurement principle is that when the pressure applied to the effective area of ​​the sensor increases, the sensor output resistance decreases, and the resistance value change is converted into a voltage value change through the signal conditioning circuit.

[0054] Figure 2Schematic diagram of the echo signal curves of training movements and standard templates. Figure (a) shows the standard template for each training movement. The height of the standard template is H, representing the pressure value; the width is W, representing the effective time of the movement. Figure (b) shows the comparison between a training movement with a shorter time and the standard template. The effective time of the entire training movement is less than the width of the standard template. Figure (c) shows the comparison between a training movement with a lower pressure and the standard template. The pressure of the entire training movement is less than the height of the standard template. Figure (d) shows the comparison between a training movement with pressure fluctuation and the standard template. The pressure fluctuation of the entire training movement is too large, and there is a large difference compared with the standard template.

[0055] Reference Figure 3 , the implementation steps of the example of the present invention are as follows:

[0056] Step 1: Training begins. After the trainee places the thin film pressure sensor 5 in the oral cavity, he or she clicks the start button. The system then gives voice prompts for the start and end time of each training action, making it easier for the trainee to conduct perioral muscle strength rhythmic training with a fixed training frequency and holding time.

[0057] Step 2: Preprocess the original echo signal to detect and extract the single perioral muscle strength training information. The criteria for determining a single effective training process are: the force value is continuously greater than 50g and the duration is greater than 1s and less than 3s.

[0058] Step 3, such as Figure 4 As shown, compared with the standard template, the effectiveness of each training action is calculated.

[0059] Assume that the height (representing the pressure value) of the standard module is H, and the width (representing the effective time of the action) is W. The actual pressure curve detected is in is the jth pressure sample of the i-th training action, j∈[1,J], J represents the number of samples in a single training action. The difference between the actual detection pressure of a single sampling point and the template pressure is:

[0060]

[0061] The first effective degree calculation formula of a single training action of the i-th training action is:

[0062]

[0063] A single training action generates a series of effective degree values ​​by sliding the standard template. The step length of the standard template can be set to natural numbers such as 1, 2, etc. For example, taking the step length of 2, the second effective degree calculation formula is:

[0064]

[0065] And so on, until W+2>J.

[0066] The generated effective degree sequence Take the minimum value, which is the effectiveness A of the i-th training action (i) .

[0067] Step 4: Graphically output the comparison between a single training movement and the standard template, so that the trainee can find their own problems (lack of strength, short duration or large force fluctuations) in the next training movement and improve their own training movement;

[0068] Step 5: Determine the overall training time set by the system. If the overall training has not ended, repeat steps 1-4. If the overall training has ended, execute step 6.

[0069] Step 6: During the whole training process, according to the system prompts, you should complete the specified number of training actions. For example, if the number of training actions is 200, for 200 effective degree A (i) Sort from small to large to form a new sequence A (j) , calculate the effectiveness of the top 90%, or 180, to obtain the training effect evaluation of the entire training process. The scoring formula is:

[0070]

[0071] Among them, Score∈[0,100], the higher the score, the better the training effect.

[0072] Step 7: Combine the historical data of the trainee and output a curve chart of the historical changes in the rhythmic training of the perioral muscles.
