[0021] The non-invasive feedback method for pelvic floor muscle training provided in this application can be executed by an electronic device, which may include, but is not limited to, laptops, desktop computers, tablets, mobile phones, and non-invasive feedback devices for pelvic floor muscle training.
[0022] The non-invasive feedback method for pelvic floor muscle training provided in this application can be applied to any scenario where the effectiveness of pelvic floor muscle training performed by a living organism needs to be determined non-invasively. For example, when a living organism is performing pelvic floor muscle training, active electrodes can be placed on the pelvic floor muscles of the organism, and then the various steps of the non-invasive feedback method for pelvic floor muscle training provided in this application can be executed through an electronic device. This allows for the non-invasive determination of the effectiveness of the pelvic floor muscle training performed by the organism, improving the safety and comfort of the pelvic floor muscle training process.
[0023] Please see Figure 1 , Figure 1 This is a flowchart illustrating the implementation of the non-invasive feedback method for pelvic floor muscle training provided in this application embodiment. The non-invasive feedback method for pelvic floor muscle training provided in this application embodiment may include S101~S102, as detailed below: In S101, during the pelvic floor muscle training process of the organism, the first electromyographic signal generated by the depolarization of the pelvic floor muscle fibers during contraction is obtained by using active electrodes placed on the pelvic floor muscles of the organism.
[0024] In one possible implementation, the active electrode can be placed in the perineum between the anus and vagina of the organism. It should be noted that since the perineum between the anus and vagina of the organism is on the surface of the organism, obtaining the first electromyographic signal generated by the depolarization of the pelvic floor muscle fibers when the pelvic floor muscles contract through the active electrode is non-invasive.
[0025] In practical applications, electronic devices can communicate with active electrodes. Based on this, the active electrodes can send the first electromyographic signal generated by the depolarization of pelvic floor muscle fibers during contraction to the electronic devices, so that the electronic devices can acquire the first electromyographic signal generated by the depolarization of pelvic floor muscle fibers during contraction.
[0026] In S102, based on the first electromyographic signal of the electronic device, it is determined whether the pelvic floor muscle training performed by the electronic device meets the preset requirements.
[0027] In this embodiment of the application, after acquiring the first electromyographic signal, the electronic device can determine, through steps a to c, whether the pelvic floor muscle training performed by the electronic device meets the preset requirements based on the first electromyographic signal, as detailed below: In step a, a second electromyographic signal generated at the target location is acquired by a reference electrode set at the target location of the organism during pelvic floor muscle training; wherein the distance between the target location and the pelvic floor muscles of the organism is less than a preset distance threshold, and the target location is located in the electrically neutral part of the organism.
[0028] In this implementation, the target location can be the anterior superior iliac spine or posterior superior iliac spine near the pelvic floor muscles. Since muscle activity is relatively low at the target location, the second electromyographic signal generated at that location can serve as a stable zero-voltage reference point, which can then be used to calibrate the first electromyographic signal.
[0029] In step b, the target electromyographic signal is determined based on the first electromyographic signal and the second electromyographic signal.
[0030] In this implementation, there can be at least two active electrodes, and each active electrode acquires a corresponding first electromyographic (EMG) signal. Specifically, the first EMG signal acquired by each active electrode can be calibrated based on the second EMG signal to obtain calibrated first EMG signals. For example, there can be two active electrodes; therefore, the first EMG signals acquired by the two active electrodes can be calibrated based on the second EMG signal to obtain calibrated first EMG signals corresponding to the two active electrodes.
[0031] Then, the target electromyographic signal can be determined based on the voltage difference between the calibrated first electromyographic signals. Specifically, the voltage difference between two calibrated first electromyographic signals can be used as the target electromyographic signal. By using the voltage difference between two calibrated first electromyographic signals as the target electromyographic signal, signal specificity can be improved and common-mode noise can be reduced.
[0032] Specifically, by calibrating each of the first electromyographic (EMG) signals using the second EMG signal, the EMG signal generated by the pelvic floor muscles between the two active electrodes can be selectively detected, while other EMG signals besides those generated by the pelvic floor muscles between the two active electrodes will not be detected, thus improving signal specificity. By determining the voltage difference between the two calibrated first EMG signals as the target EMG signal, the EMG signal present on both active electrodes can be eliminated, thereby reducing common-mode noise (such as environmental electrical interference or motion artifacts).
[0033] In step c, based on the target electromyographic signal, it is determined whether the pelvic floor muscle training performed by the organism meets the preset requirements.
[0034] In this implementation, after obtaining the target electromyographic signal, the maximum voluntary contraction signal value of the pelvic floor muscles of the organism can be obtained first, and the target electromyographic signal can be normalized according to the maximum voluntary contraction signal value. Then, based on the maximum voluntary contraction signal value and the normalized target electromyographic signal, it can be determined whether the pelvic floor muscle training performed by the organism meets the preset requirements.
[0035] Among them, the maximum voluntary contraction signal value is a standard measurement index in electromyography, defined as the maximum muscle activity or force that an organism can voluntarily generate when the pelvic floor muscles contract to the maximum extent.
[0036] In practical applications, the maximum voluntary contraction signal value can be determined by an electronic device based on the electromyography (EMG) of the pelvic floor muscles of the organism. For example, before pelvic floor muscle training, the organism can perform two maximum pelvic floor muscle contractions. The electronic device can acquire the EMG of the pelvic floor muscles of the organism through active electrodes and reference electrodes, and determine the peak amplitude of the EMG corresponding to each of the two maximum pelvic floor muscle contractions. The average value of the peak amplitude of the EMG corresponding to each of the two maximum pelvic floor muscle contractions is then determined as the maximum voluntary contraction signal value.
[0037] In one possible implementation, the electronic device can determine whether the pelvic floor muscle training performed by the organism meets preset requirements based on the maximum voluntary contraction signal value and the normalized target electromyographic signal through steps d to f, as detailed below: In step d, based on the normalized target electromyographic signal, the third electromyographic signal of the pelvic floor muscles of the organism during the relaxation period of pelvic floor muscle training is determined, and the fourth electromyographic signal of the pelvic floor muscles of the organism during the movement period of pelvic floor muscle training is determined.
[0038] In this implementation, the pelvic floor muscle training performed by the organism includes a relaxation phase and an exercise phase. Furthermore, there is a significant difference between the third electromyographic signal of the pelvic floor muscles during the relaxation phase and the fourth electromyographic signal of the pelvic floor muscles during the exercise phase. Based on this, the electronic device can determine the third electromyographic signal of the pelvic floor muscles during the relaxation phase and the fourth electromyographic signal of the pelvic floor muscles during the exercise phase by a preset method.
[0039] In step e, the pelvic floor muscle activation threshold is determined based on the mean and standard deviation of the third electromyographic signal.
[0040] In this implementation, after determining the third electromyographic signal of the pelvic floor muscles during the relaxation period of the organism during pelvic floor muscle training, the mean and standard deviation of the third electromyographic signal can be calculated separately. The pelvic floor muscle activation threshold can then be determined based on the mean and standard deviation of the third electromyographic signal using the following formula: Pelvic floor muscle activation threshold = mean of third electromyography (EMG) signal + a × standard deviation of third EMG signal Where 'a' is a preset coefficient, and in practical applications, 'a' can be 3.
[0041] The pelvic floor muscle activation threshold can be used to determine whether the pelvic floor muscles of an organism are activated. For example, if the amplitude of the electromyographic signal corresponding to the electromyographic signal is greater than or equal to the pelvic floor muscle activation threshold, it can be considered that the pelvic floor muscles of the organism are being activated, and thus it can be considered that this is the exercise phase of pelvic floor muscle training. If the amplitude of the electromyographic signal corresponding to the electromyographic signal is less than the pelvic floor muscle activation threshold, it can be considered that the pelvic floor muscles of the organism are not activated, and thus it can be considered that this is the relaxation phase of pelvic floor muscle training.
[0042] In step f, based on the pelvic floor muscle activation threshold, the third electromyographic signal, and the fourth electromyographic signal, it is determined whether the pelvic floor muscle training performed by the organism meets the preset requirements.
[0043] In this implementation, the electronic device can first determine the duration of each contraction, the duration of each relaxation, and the maximum amplitude of each contraction during pelvic floor muscle training based on the pelvic floor muscle activation threshold, the third electromyographic signal, and the fourth electromyographic signal.
[0044] Specifically, the electronic device can determine the duration for which the amplitude of the fourth electromyography (EMG) signal is greater than or equal to the pelvic floor muscle activation threshold each time, and further determine the duration of each contraction based on the duration for which the amplitude of the fourth EMG signal is greater than or equal to the pelvic floor muscle activation threshold each time. For example, if the duration for which the amplitude of the first fourth EMG signal is greater than or equal to the pelvic floor muscle activation threshold is t1, the duration for the second fourth EMG signal is t2, and the duration for the third fourth EMG signal is t3, then the duration of each contraction is t1, t2, and t3.
[0045] Specifically, the electronic device can determine the duration for which the amplitude of the third electromyography (EMG) signal is less than the pelvic floor muscle activation threshold each time, and further determine the duration of each relaxation based on the duration of the third EMG signal being less than the pelvic floor muscle activation threshold each time. For example, if the duration for which the amplitude of the third EMG signal is less than the pelvic floor muscle activation threshold for the first time is t4, the duration for ...
[0046] Specifically, the electronic device can determine the maximum amplitude of the fourth electromyographic signal during each pelvic floor muscle contraction based on the fourth electromyographic signal. Therefore, based on the determined maximum amplitude of the fourth electromyographic signal during each pelvic floor muscle contraction, the maximum amplitude of each contraction can be determined. For example, if the maximum amplitude of the fourth electromyographic signal during the first pelvic floor muscle contraction is n1, the maximum amplitude during the second pelvic floor muscle contraction is n2, and the maximum amplitude during the third pelvic floor muscle contraction is n3, then the maximum amplitude of each contraction can be determined as n1, n2, and n3.
[0047] Then, the electronic device can determine whether the pelvic floor muscle training performed by the organism meets the preset requirements based on the duration of each contraction, the duration of each relaxation, the maximum amplitude of each contraction, the maximum voluntary contraction signal value, and the pelvic floor muscle activation threshold.
[0048] Specifically, the electronic device can determine whether the duration of each contraction, the duration of each relaxation, the maximum amplitude of each contraction, and the pelvic floor muscle activation threshold meet preset requirements.
[0049] For example, an electronic device can determine whether the duration of each contraction meets the preset requirements in the following way: if each sub-time in the duration of each contraction is greater than a preset first duration threshold, and the standard deviation of each contraction duration is less than a preset first standard deviation threshold, then the duration of each contraction meets the preset requirements; if any sub-time in the duration of contraction is less than or equal to the preset first duration threshold, or the standard deviation of each contraction duration is greater than or equal to the preset first standard deviation threshold, then the duration of each contraction does not meet the preset requirements.
[0050] For example, an electronic device can determine whether the duration of each relaxation meets the preset requirements in the following ways: if each sub-time in each relaxation duration is greater than a preset second duration threshold, and the standard deviation of each relaxation duration is less than a preset second standard deviation threshold, then the duration of each relaxation meets the preset requirements; if any sub-time in each relaxation duration is less than or equal to the preset second duration threshold, or the standard deviation of each relaxation duration is greater than or equal to the preset second standard deviation threshold, then the duration of each relaxation does not meet the preset requirements.
[0051] For example, an electronic device can determine whether the maximum contraction value meets the preset requirements in the following ways: if each sub-maximum value in the maximum contraction value is greater than a preset amplitude threshold, and the standard deviation of the maximum contraction value is less than a preset third standard deviation threshold, then the maximum contraction value meets the preset requirements; if any sub-maximum value in the maximum contraction value is less than or equal to a preset amplitude threshold, or the standard deviation of the maximum contraction value is greater than or equal to a preset third standard deviation threshold, then the maximum contraction value does not meet the preset requirements.
[0052] For example, an electronic device can determine whether the pelvic floor muscle activation threshold meets the preset requirements in the following way: based on the maximum voluntary contraction signal value, a reasonable threshold range is determined. For example, (10% of the maximum voluntary contraction signal value and 50% of the maximum voluntary contraction signal value) can be determined as the reasonable threshold range. After determining the reasonable threshold range, if the pelvic floor muscle activation threshold is within the reasonable threshold range, it can be determined that the pelvic floor muscle activation threshold meets the preset requirements. If the pelvic floor muscle activation threshold is not within the reasonable threshold range, it can be determined that the pelvic floor muscle activation threshold does not meet the preset requirements.
[0053] After determining whether the duration of each contraction, the duration of each relaxation, the maximum amplitude of each contraction, and the pelvic floor muscle activation threshold meet the preset requirements, if any parameter among the duration of each contraction, the duration of each relaxation, the maximum amplitude of each contraction, and the pelvic floor muscle activation threshold does not meet the preset requirements, it can be determined that the pelvic floor muscle training performed by the organism does not meet the preset requirements. If the duration of each contraction, the duration of each relaxation, the maximum amplitude of each contraction, and the pelvic floor muscle activation threshold all meet the preset requirements, it can be determined that the pelvic floor muscle training performed by the organism meets the preset requirements.
[0054] Optionally, the electronic device can also send signals to the organism in a preset manner to indicate whether the pelvic floor muscle training performed by the organism meets preset requirements. For example, if the electronic device determines that the pelvic floor muscle training performed by the organism meets the preset requirements, it can control the green light in the electronic device to turn on and the red light in the electronic device to turn off; if the electronic device determines that the pelvic floor muscle training performed by the organism does not meet the preset requirements, it can control the red light in the electronic device to turn on and the green light in the electronic device to turn off.
[0055] In one possible implementation, the electronic device can determine not only whether the pelvic floor muscle training performed by the organism meets preset requirements, but also a quality score for the pelvic floor muscle training performed by the organism. Optionally, the electronic device can determine the quality score of the pelvic floor muscle training performed by the organism through steps g to h, as detailed below: In step g, based on the pelvic floor muscle activation threshold, the third electromyographic signal, and the fourth electromyographic signal, the root mean square value of the electromyographic signal during each contraction of the organism during pelvic floor muscle training, the total duration of the organism's pelvic floor muscle training, and the trend of the organism's fatigue level during pelvic floor muscle training are determined.
[0056] In this implementation, the electronic device can determine each contraction phase of the organism during pelvic floor muscle training based on the fourth electromyographic signal, and determine the root mean square value of the fourth electromyographic signal corresponding to each contraction phase based on the fourth electromyographic signal corresponding to each contraction phase, thereby obtaining the root mean square value of the electromyographic signal during each contraction phase of the organism during pelvic floor muscle training.
[0057] In this implementation, the electronic device can determine the start time of the first contraction phase and the end time of the last contraction phase based on the pelvic floor muscle activation threshold, the third electromyographic signal, and the fourth electromyographic signal. Thus, the total duration of pelvic floor muscle training can be determined based on the start time of the first contraction phase and the end time of the last contraction phase.
[0058] In this implementation, the electronic device can determine the trend of electromyographic signal changes in the organism during pelvic floor muscle training based on the third and fourth electromyographic signals, and determine the trend of fatigue level changes in the organism during pelvic floor muscle training based on the trend of electromyographic signal changes in the organism during pelvic floor muscle training.
[0059] In step h, the quality score of the pelvic floor muscle training performed by the organism is determined based on the duration of each contraction, the duration of each relaxation, the maximum amplitude of each contraction, the maximum voluntary contraction signal value, the pelvic floor muscle activation threshold, the maximum amplitude of each contraction, the root mean square value of the electromyographic signal during each contraction, the total duration, and the trend of fatigue level.
[0060] In this implementation, the electronic device can determine sub-scores for each of the following parameters based on the duration of each contraction, the duration of each relaxation, the maximum amplitude of each contraction, the maximum voluntary contraction signal value, the pelvic floor muscle activation threshold, the maximum amplitude of each contraction, the root mean square value of the electromyographic signal during each contraction, the total duration, and the trend of fatigue level. Then, based on the sub-scores and their corresponding weighting coefficients for each of these parameters, the quality score of the pelvic floor muscle training performed by the organism can be determined.
[0061] Then, the electronic device can output the quality score of the pelvic floor muscle training performed by the organism to the organism in a preset manner, so that the organism can improve the pelvic floor muscle training based on the quality score of the pelvic floor muscle training performed by the organism, thereby improving the effect of the pelvic floor muscle training performed by the organism.
[0062] As can be seen from the above, in the non-invasive feedback method for pelvic floor muscle training provided in this application embodiment, firstly, during the pelvic floor muscle training process, the first electromyographic signal generated by the depolarization of pelvic floor muscle fibers during contraction is obtained by using active electrodes placed on the pelvic floor muscles of the organism. Then, based on the first electromyographic signal, it is determined whether the pelvic floor muscle training performed by the organism meets the preset requirements. Since the first electromyographic signal used to determine whether the pelvic floor muscle training performed by the organism meets the preset requirements is obtained by active electrodes placed on the pelvic floor muscles of the organism, and since the active electrodes can be directly attached to the skin, the effect of pelvic floor muscle training can be determined without the use of a vaginal probe. Therefore, the effect of pelvic floor muscle training performed by the organism can be determined non-invasively, improving the safety and comfort of the pelvic floor muscle training process.
