[0021] The execution subject of the non-invasive feedback method for pelvic floor muscle training provided in the embodiments of this application can be an electronic device, wherein the electronic device may include, but is not limited to, electronic devices such as laptops, desktop computers, tablet computers, 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 embodiment can be applied to any scenario where it is necessary to non-invasively determine the effect of pelvic floor muscle training performed by an organism. For example, if an 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 embodiment can be executed through an electronic device, thereby non-invasively determining the effect of pelvic floor muscle training performed by the organism, improving the safety and comfort of the pelvic floor muscle training process.

[0023] Please refer to Figure 1. Figure 1 is a flowchart of 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, which are detailed below: In S101, during pelvic floor muscle training of an organism, the first electromyographic signal generated by the depolarization of pelvic floor muscle fibers during contraction is obtained by an active electrode set on the pelvic floor muscles of the organism.

[0024] In one possible implementation, the active electrode may be specifically set 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 pelvic floor muscle fibers during contraction of the organism through the active electrode is non-invasive.

[0025] In practical applications, electronic devices can be communicatively connected to the active electrode. Based on this, the active electrode can obtain the first electromyographic signal generated by the depolarization of pelvic floor muscle fibers during contraction.The first electromyographic signal generated by the depolarization of the pelvic floor muscle fibers when the pelvic floor muscles of the organism contract is sent to the electronic device so that the electronic device can acquire the first electromyographic signal generated by the depolarization of the pelvic floor muscle fibers when the pelvic floor muscles of the organism contract.

[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 organism 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 whether the pelvic floor muscle training performed by the organism by the electronic device meets the preset requirements based on the first electromyographic signal of the electronic device through steps a to c, as detailed below: In step a, a second electromyographic signal generated at the target position during the pelvic floor muscle training of the organism is acquired by a reference electrode set at the target position of the organism; wherein, the distance between the target position and the pelvic floor muscles of the organism is less than a preset distance threshold, and the target position is located in the electrically neutral part of the organism.

[0028] In this implementation, the target position can be the anterior superior iliac spine / posterior superior iliac spine near the pelvic floor muscles. Since there is less muscle activity at the target location, the second electromyographic signal generated at the target location can be used 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 and second electromyographic signals.

[0030] In this implementation, the number of active electrodes can be at least two, and each active electrode acquires a corresponding first electromyographic signal. Specifically, the first electromyographic signal acquired by each active electrode can be calibrated based on the second electromyographic signal to obtain calibrated first electromyographic signals. For example, the number of active electrodes can be two, and based on this, the first electromyographic signals acquired by the two active electrodes can be calibrated based on the second electromyographic signal to obtain calibrated first electromyographic 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 the calibrated two first electromyographic signals can be determined as the target electromyographic signal. By determining the voltage difference between the 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 first electromyographic signal with the second electromyographic signal, electromyographic signals generated by the pelvic floor muscles between the two active electrodes can be selectively detected, while other electromyographic 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 electromyographic signals as the target electromyographic signal, electromyographic signals present on both active electrodes can be eliminated, as described on page 4 / 10 of the specification, CN 121662416 A.This can reduce common-mode noise (e.g., environmental electrical interference or motion artifacts).

[0033] In step c, based on the target electromyography (EMG) 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 EMG signal, the maximum voluntary contraction signal value of the pelvic floor muscles of the organism can be obtained first, and the target EMG signal can be normalized based on the maximum voluntary contraction signal value. Then, based on the maximum voluntary contraction signal value and the normalized target EMG signal, it can be determined whether the pelvic floor muscle training performed by the organism meets the preset requirements.

[0035] The maximum voluntary contraction signal value is a standard measurement index in electromyography, defined as the maximum muscle activity or force that the organism can generate voluntarily 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 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 electromyography (EMG) of the organism's pelvic floor muscles through the active electrode and the reference electrode, and determine the peak amplitude of the EMG corresponding to each of the two maximum pelvic floor muscle contractions, thereby determining the average value of the peak amplitude of the EMG corresponding to each of the two maximum pelvic floor muscle contractions 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 the preset requirements based on the maximum voluntary contraction signal value and the normalized target EMG signal through steps d to f, as detailed below: In step d, based on the normalized target EMG signal, the third EMG signal of the organism's pelvic floor muscles during the relaxation period of the organism during pelvic floor muscle training is determined, and the fourth EMG signal of the organism's pelvic floor muscles during the movement period of the organism during pelvic floor muscle training is determined.

[0038] In this implementation, the pelvic floor muscle training performed by the organism includes a relaxation period and an exercise period. There is a significant difference between the third electromyographic (EMG) signal of the pelvic floor muscles during the relaxation period and the fourth EMG signal during the exercise period. Based on this, the electronic device can determine the third EMG signal of the pelvic floor muscles during the relaxation period and the fourth EMG signal during the exercise period using a preset method.

[0039] In step e, the pelvic floor muscle activation threshold is determined based on the average value and standard deviation of the third EMG signal.

[0040] In this implementation, after determining the third EMG signal of the pelvic floor muscles during the relaxation period of the organism's pelvic floor muscle training, the average value and standard deviation of the third EMG signal can be calculated respectively. The pelvic floor muscle activation threshold can be determined based on the average value and standard deviation of the third EMG signal using the following formula: Pelvic floor muscle activation threshold= Average value of the third electromyographic signal + a × Standard deviation of the third electromyographic 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 period of the pelvic floor muscle training performed by the organism. 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 period of the pelvic floor muscle training performed by the organism.

[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 electromyographic signal is greater than or equal to the pelvic floor muscle activation threshold based on the fourth electromyographic signal, and then determine the duration of each contraction based on the duration for which the amplitude of the fourth electromyographic signal is greater than or equal to the pelvic floor muscle activation threshold. For example, if the duration for which the amplitude of the first fourth electromyographic signal is greater than or equal to the pelvic floor muscle activation threshold is t1, the duration for which the amplitude of the second fourth electromyographic signal is greater than or equal to the pelvic floor muscle activation threshold is t2, and the duration for which the amplitude of the third fourth electromyographic signal is greater than or equal to the pelvic floor muscle activation threshold 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 electromyographic signal is less than the pelvic floor muscle activation threshold each time based on the third electromyographic signal, and then determine the duration of each relaxation based on the duration for which the amplitude of the third electromyographic signal is less than the pelvic floor muscle activation threshold each time. For example, if the duration for which the amplitude of the third electromyographic signal is less than the pelvic floor muscle activation threshold for the first time is t4, the duration for which the amplitude of the third electromyographic signal is less than the pelvic floor muscle activation threshold for the second time is t5, and the duration for which the amplitude of the third electromyographic signal is less than the pelvic floor muscle activation threshold for the third time is t6, then the duration of each relaxation is t4, t5, and t6.

[0046] Specifically, the electronic device can determine the maximum amplitude value of the fourth electromyographic signal corresponding to each pelvic floor muscle contraction based on the fourth electromyographic signal, and then determine the relaxation duration based on the maximum amplitude value of the fourth electromyographic signal corresponding to each pelvic floor muscle contraction.The maximum amplitude of each contraction is determined. For example, if the maximum amplitude of the fourth electromyographic signal corresponding to the first pelvic floor muscle contraction is n1, the maximum amplitude of the fourth electromyographic signal corresponding to the second pelvic floor muscle contraction is n2, and the maximum amplitude of the fourth electromyographic signal corresponding to the third pelvic floor muscle contraction is n3, then the maximum amplitude of each contraction can be determined as n1, n2, and n3.

[0047] Subsequently, 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 the preset requirements.

[0049] For example, the electronic device can determine whether the duration of each contraction meets the preset requirement 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 requirement; 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 duration of contraction is greater than or equal to the preset first standard deviation threshold, then the duration of each contraction does not meet the preset requirement.

[0050] For example, the electronic device can determine whether the duration of each relaxation meets the preset requirement in the following way: if each sub-time in the duration of each relaxation 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 requirement; if any sub-time in the duration of relaxation 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 requirement.

[0051] For example, the electronic device can determine whether the maximum amplitude of each contraction meets the preset requirement in the following way: if each sub-maximum amplitude in the maximum amplitude of each contraction is greater than a preset amplitude threshold, and the standard deviation of the maximum amplitude of each contraction is less than a preset third standard deviation threshold, then it can be determined that the maximum amplitude of each contraction meets the preset requirement;

[0052] For example, the electronic device can determine whether the pelvic floor muscle activation threshold meets the preset requirement 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 a 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 a signal to the organism in a preset manner to prompt whether the pelvic floor muscle training performed by the organism meets the 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, in addition to determining whether the pelvic floor muscle training performed by the organism meets the preset requirements, the electronic device can also determine the quality score of 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 determining 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, thereby determining the root mean square value of the electromyographic signal during each contraction phase of the organism during pelvic floor muscle training.The start time of the contraction phase and the end time of the last contraction phase are used to determine the total duration of pelvic floor muscle training for the organism.

[0058] In this implementation, the electronic device can determine the trend of electromyographic signal changes during pelvic floor muscle training based on the third and fourth electromyographic signals, and determine the trend of fatigue level changes during pelvic floor muscle training based on the trend of electromyographic signal changes during pelvic floor muscle training.

[0059] In step h, the quality score of 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 changes.

[0060] In this implementation, the electronic device can determine the sub-scores corresponding to each of the following parameters: duration of each contraction, duration of each relaxation, maximum amplitude of each contraction, maximum voluntary contraction signal value, pelvic floor muscle activation threshold, maximum amplitude of each contraction, root mean square value of electromyography signal during each contraction, total duration, and fatigue level trend. Then, based on the sub-scores and their corresponding weighting coefficients corresponding to each of these parameters, the electronic device can determine the quality score of the pelvic floor muscle training performed by the organism.

[0061] Subsequently, 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 performed by the organism 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 the embodiments of this application, firstly, during the pelvic floor muscle training process of the organism, the first electromyographic signal generated by the depolarization of the pelvic floor muscle fibers when the pelvic floor muscle contracts is obtained by the active electrode set on the pelvic floor muscle 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 in this method is obtained by the active electrode set on the pelvic floor muscle of the organism, and since the active electrode can be directly attached to the skin, the effect of pelvic floor muscle training can be determined without the use of a vaginal probe, thus eliminating the need for a vaginal probe.The effectiveness of pelvic floor muscle training performed on the organism is determined invasively, improving the safety and comfort of the pelvic floor muscle training process.
