Description

Technical Field

[0001] The present invention relates to the field of medical technology, and in particular to a pelvic floor muscle training system. Background Art

[0002] Currently, magnetic stimulation training for the pelvic floor muscles involves placing the pelvic floor muscles within a magnetic field. The high-intensity, varying magnetic field emitted by the device stimulates the pelvic floor nerves to achieve the effect of passive contraction of the pelvic floor muscles. During magnetic stimulation training, the subject is instructed to actively contract their pelvic floor muscles. The pelvic floor muscle strength feedback from the training system determines the subject's pelvic floor muscle status, allowing adjustments to be made to the pelvic floor muscle training. However, during the use of current pelvic floor muscle training systems, the abdominal muscles assist in the contraction of the pelvic floor muscles during active contraction. Consequently, excessive abdominal muscle exertion often results in inaccurate pelvic floor muscle strength measurements. Summary of the Invention

[0003] In view of this, the present invention provides a pelvic floor muscle training system to solve the problem of inaccurate pelvic floor muscle strength measurement due to excessive abdominal muscle exertion.

[0004] The present invention provides a pelvic floor muscle training system, which includes a pelvic floor pressure detection device, an abdominal myoelectric detection device, and a controller, wherein the controller is connected to the pelvic floor pressure detection device and the abdominal myoelectric detection device respectively; wherein the controller is used to:

[0005] receiving the pelvic floor muscle pressure signal collected by the pelvic floor pressure detection device and the abdominal myoelectric signal collected by the abdominal myoelectric detection device;

[0006] determining a target engagement degree of the abdominal muscles during pelvic floor muscle contraction based on a correlation between the pelvic floor muscle pressure signal and the abdominal myoelectric signal;

[0007] Output corresponding prompt information based on the target participation level.

[0008] In this method, by configuring an abdominal electromyography detection device, a controller receives the pelvic floor muscle pressure signal collected by the pressure detection device and the abdominal electromyography signal collected by the abdominal electromyography detection device, and determines the target engagement of the abdominal muscles during pelvic floor muscle contraction based on the correlation between the pelvic floor muscle pressure signal and the abdominal electromyography signal, thereby outputting corresponding prompt information based on the target engagement. Therefore, during training, when excessive abdominal muscle exertion is detected, corresponding prompt information can be output to prevent the subject from overusing the abdominal muscles to assist the pelvic floor muscles in exerting force, and to prevent the abdominal muscles from interfering with the measurement of pelvic floor muscle strength, thereby improving the accuracy of pelvic floor muscle strength measurement.

[0009] In an optional embodiment, the controller is configured to determine a target engagement of the abdominal muscles during pelvic floor muscle contraction based on a correlation between the pelvic floor muscle pressure signal and the abdominal myoelectric signal, including:

[0010] The controller is used to:

[0011] Obtaining a pelvic floor muscle pressure waveform and an abdominal electromyography waveform based on the pelvic floor muscle pressure signal and the abdominal electromyography signal;

[0012] Analyzing the pelvic floor muscle pressure waveform to determine a pelvic floor muscle contraction area in the pelvic floor muscle pressure waveform;

[0013] Determining the abdominal muscle contraction area corresponding to the abdominal electromyography waveform based on the pelvic floor muscle contraction area;

[0014] The target engagement degree is obtained based on a correlation between a pelvic floor muscle pressure signal in the pelvic floor muscle contraction area and an abdominal myoelectric signal in the abdominal muscle contraction area.

[0015] In this method, the controller first analyzes the generated pelvic floor muscle pressure waveform to determine the pelvic floor muscle contraction area in the pelvic floor muscle pressure waveform, and then determines the abdominal muscle contraction area corresponding to the generated abdominal electromyography waveform based on the pelvic floor muscle contraction area, so as to avoid interference with the judgment of the abdominal muscle participation due to the abdominal muscle force when the pelvic floor muscle is relaxed. Therefore, based on the correlation between the pelvic floor muscle pressure signal in the pelvic floor muscle contraction area and the abdominal electromyography signal in the abdominal muscle contraction area, the target participation of the abdominal muscles during pelvic floor muscle contraction can be accurately obtained.

[0016] In an optional embodiment, the controller is configured to obtain the target engagement based on a correlation between a pelvic floor muscle pressure signal in the pelvic floor muscle contraction area and an abdominal myoelectric signal in the abdominal muscle contraction area, including:

[0017] The controller is used to:

[0018] Determining a correlation between a pelvic floor muscle pressure signal within the pelvic floor muscle contraction region and an abdominal myoelectric signal within the abdominal muscle contraction region;

[0019] The target engagement level is determined based on the correlation and the abdominal electromyographic signal within the abdominal muscle contraction area.

[0020] In this method, the correlation between the pelvic floor muscle pressure signal in the pelvic floor muscle contraction area and the abdominal electromyographic signal in the abdominal muscle contraction area is first determined, and then the abdominal electromyographic signal in the abdominal muscle contraction area is processed based on the correlation. Therefore, the target involvement of the abdominal muscles during pelvic floor muscle contraction can be quickly determined.

[0021] In an optional embodiment, the controller is configured to determine the target engagement based on the correlation and the abdominal electromyographic signal in the abdominal muscle contraction area, including:

[0022] The controller is used to:

[0023] Analyze the waveform in the abdominal muscle contraction area to determine the abdominal electromyographic signal corresponding to the contraction peak in the abdominal muscle contraction area;

[0024] Calculating the degree of engagement of the abdominal muscles corresponding to each contraction peak based on the correlation corresponding to each contraction peak in the contraction area and the abdominal electromyographic signal;

[0025] The target engagement level is obtained based on the average of all the engagement levels.

[0026] In this method, the abdominal EMG signals corresponding to the contraction peaks within the contraction area are first determined. Based on the correlation between the contraction peaks within the contraction area and the abdominal EMG signals, the degree of abdominal muscle engagement corresponding to each contraction peak is calculated. The target degree of abdominal muscle engagement is then determined based on the average of these contraction peaks. This allows for a comprehensive assessment of abdominal muscle engagement during pelvic floor muscle contraction, preventing the influence of individual detection errors or brief abdominal muscle exertion on the assessment of abdominal muscle engagement.

[0027] In an optional implementation, the controller is configured to output corresponding prompt information based on the target engagement, including:

[0028] The controller is used to:

[0029] If the target participation is greater than a preset threshold, the prompt information is output.

[0030] In this method, when the target engagement exceeds a preset threshold, the controller is configured to output a prompt message. This prevents excessive abdominal muscle engagement from interfering with the pelvic floor muscles, ensuring accurate pelvic floor muscle strength measurement.

[0031] In an optional embodiment, the system includes a prompt device, which is connected to the controller and is used to output the prompt information through text and / or graphics and / or voice.

[0032] In this manner, a prompting device is provided in the system for outputting the prompting information via text and / or graphics and / or voice, thereby enabling the training subject to timely understand the current engagement status of the abdominal muscles.

[0033] In an optional embodiment, the system further comprises a magnetic stimulation output device connected to the controller, and the controller is further configured to:

[0034] Based on the waveform characteristics corresponding to the pelvic floor muscle contraction area, obtaining the current maximum muscle force value corresponding to the current adjustment cycle when the pelvic floor muscle contracts;

[0035] Get the historical maximum muscle strength value corresponding to the previous adjustment cycle;

[0036] Based on the historical maximum muscle strength value and the current maximum muscle strength value, a current pelvic floor muscle pressure threshold is determined, and the current pelvic floor muscle pressure threshold is used to determine the triggering condition of the magnetic stimulation output device.

[0037] In this method, the controller determines the current maximum muscle force value corresponding to the current adjustment cycle of pelvic floor muscle contraction based on the waveform characteristics of the pelvic floor muscle contraction area, and obtains the historical maximum muscle force value corresponding to the previous adjustment cycle to determine the current pelvic floor muscle pressure threshold, thereby automatically adjusting the trigger conditions of the magnetic stimulation output device to ensure the accuracy of the pelvic floor muscle pressure threshold. Therefore, during training, the trigger conditions of the magnetic stimulation output device can be made more closely aligned with the actual training situation of the training subject, avoiding the problem of the initial maximum muscle force value being too large, resulting in no stimulation, or the initial maximum muscle force value being too small, resulting in stimulation without the pelvic floor muscle contracting forcefully.

[0038] In an optional embodiment, the system includes a first operating mode and a second operating mode, the second operating mode being subsequent to the first operating mode, and the controller is further configured to:

[0039] Obtaining a target maximum muscle strength value when the pelvic floor muscles contract in the first working mode;

[0040] Obtaining a spacing adjustment coefficient corresponding to each operating parameter of the magnetic stimulation output device;

[0041] Based on the target maximum muscle force value and the interval adjustment coefficients corresponding to the respective pulse parameters, the respective operating parameters of the magnetic stimulation output device in the second operating mode are determined.

[0042] In this approach, the controller determines the various operating parameters of the magnetic stimulation output device in the second operating mode based on the target maximum muscle force value during pelvic floor muscle contraction in the first operating mode and the spacing adjustment coefficients corresponding to the various operating parameters of the magnetic stimulation output device. This improves the accuracy of adjusting the various operating parameters of the pelvic floor muscle training system, ensuring that the various operating parameters of the magnetic stimulation output device in the second operating mode are consistent with the actual conditions of the training subject, thereby achieving better pelvic floor muscle training results.

[0043] In an optional embodiment, the controller is further configured to:

[0044] Obtaining a current working submode of the pelvic floor muscle training system to determine a target muscle strength reference value corresponding to the current working submode, where the current working submode is one of the submodes included in the first working mode and the second working mode;

[0045] Processing the maximum muscle strength value of the pelvic floor muscle during contraction based on the target muscle strength parameter value to obtain a pelvic floor muscle contraction score;

[0046] Pelvic floor muscle contraction feedback information is generated based on the pelvic floor muscle contraction score.

[0047] In this approach, the controller processes the maximum muscle force value during pelvic floor muscle contraction based on the target muscle force reference value corresponding to the current operating submode to obtain a pelvic floor muscle contraction score, thereby generating corresponding pelvic floor muscle contraction feedback information. This allows for timely understanding of the subject's actual pelvic floor muscle contraction status, enabling the system's operating state to be adjusted accordingly, ensuring the accuracy of parameter adjustment for the pelvic floor muscle training system.

[0048] In an optional embodiment, the controller is further configured to:

[0049] Calculating the average of the maximum muscle force values ​​during a single contraction of the pelvic floor muscles to obtain the average maximum muscle force;

[0050] Analyzing the degree of muscle weakness during pelvic floor muscle contraction based on the maximum muscle strength average to obtain pelvic floor muscle fatigue;

[0051] Pelvic floor muscle fatigue feedback information is generated based on the pelvic floor muscle fatigue.

[0052] In this approach, the controller analyzes the degree of muscle weakening during pelvic floor muscle contraction based on the average maximum muscle force during contraction, determining pelvic floor muscle fatigue and generating pelvic floor muscle fatigue feedback information. This allows for timely understanding of the subject's pelvic floor muscle fatigue and accurate adjustment of the pelvic floor muscle training system's operating state.

[0053] In an optional embodiment, the system includes a display device connected to the controller, and the controller is further configured to:

[0054] Obtaining a current pelvic floor muscle pressure waveform corresponding to a current display page of the display device;

[0055] Determine a pelvic floor muscle relaxation area in the current pelvic floor muscle pressure waveform, where the pelvic floor muscle relaxation area is other areas in the current pelvic floor muscle pressure waveform except the pelvic floor muscle contraction area;

[0056] Obtaining a baseline muscle strength value based on a pelvic floor muscle pressure waveform characteristic corresponding to the pelvic floor muscle relaxation area;

[0057] Based on the waveform characteristics corresponding to the pelvic floor muscle contraction area in the current pelvic floor muscle pressure waveform, obtaining the maximum muscle force value of the pelvic floor muscle contraction corresponding to the current pelvic floor muscle pressure waveform;

[0058] Determining a coordinate axis height corresponding to the current page based on the maximum muscle force value corresponding to the current pelvic floor muscle pressure waveform, the reference muscle force value, and a preset redundant height;

[0059] The current pelvic floor muscle pressure waveform is displayed on the current page based on the coordinate axis height.

[0060] In this approach, the controller determines the coordinate axis height corresponding to the current page based on the maximum muscle force value of the pelvic floor muscle contraction corresponding to the current pelvic floor muscle pressure waveform, the baseline muscle force value corresponding to the pelvic floor muscle relaxation, and a preset redundant height, and dynamically adjusts the current page to display the current pelvic floor muscle pressure waveform. This ensures that the entire pelvic floor muscle pressure waveform fits within the display device's screen, providing real-time feedback of the complete pelvic floor muscle pressure signal.

[0065] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0066] Common pelvic floor muscle training methods include electrical stimulation training in physical training. Among them, electrical stimulation training mainly adopts an invasive training method, which places vaginal electrodes or other invasive probes in the vagina to collect pelvic floor electromyographic signals and electrical stimulation output, thereby realizing pelvic floor muscle signal monitoring, feedback training, and electrical stimulation training. However, some women express discomfort, embarrassment, or resistance to this common invasive training method because vaginal electrode training involves private parts, which leads to privacy protection issues. This limits the acceptability and training effect of invasive training.

[0067] Magnetic stimulation training is a non-invasive method that allows participants to train while clothed, is quick to achieve results, is simple and painless, and protects the participant's privacy. Therefore, it has attracted widespread attention. Currently, magnetic stimulation training for the pelvic floor muscles involves placing the pelvic floor muscles within a magnetic field. The device's high-intensity, varying magnetic field stimulates the pelvic floor nerves, achieving passive contraction of the pelvic floor muscles. However, these magnetic stimulation training devices typically monitor only the pelvic floor muscle electromyography (EMG) signal or other single signals, failing to comprehensively assess pelvic floor muscle effort and the involvement of synergistic muscles. The in vitro biofeedback training modules in these devices also only measure changes in overall pelvic floor muscle pressure. Pelvic floor muscle contraction may utilize the strength of other muscles, such as the abdominals, gluteal muscles, and adductors; pelvic floor muscle contraction primarily coordinates with the abdominal muscles. Therefore, single-channel pelvic floor EMG feedback signals cannot reflect the involvement of the abdominal muscles in simultaneous pelvic floor muscle contraction, leading to inaccurate pelvic floor muscle force measurements and preventing trainers from assessing the participant's true training performance.

[0068] In view of this, a pelvic floor muscle training system is provided in this embodiment. Figure 1 FIG is a schematic structural diagram of a pelvic floor muscle training system according to an embodiment of the present invention. Figure 1 As shown, the system includes a magnetic stimulation output device, a pelvic floor pressure detection device, an abdominal myoelectric detection device, and a controller. The magnetic stimulation output device is used to generate electromagnetic pulses, the pelvic floor pressure detection device is used to collect pelvic floor muscle pressure signals, and the abdominal myoelectric detection device is used to collect abdominal myoelectric signals.

[0069] In some optional embodiments, the abdominal electromyography detection device includes an abdominal electrode sheet 1 and an abdominal electromyography monitoring module 2, wherein the abdominal electrode sheet 1 is used to sense the degree of tightening of the abdominal muscles and convert it into an electric charge, and the abdominal electromyography monitoring module 2 is connected to the abdominal electrode sheet 1 and the controller, respectively, and the abdominal electromyography monitoring module 2 is used to convert the electric charge into an abdominal electromyography signal. In the pelvic floor muscle training system provided in this embodiment, the abdominal electromyography detection device is provided with an abdominal electrode sheet 1 and an abdominal electromyography monitoring module 2, so that the degree of tightening of the abdominal muscles can be sensed in real time to convert it into an abdominal electromyography signal, so as to accurately determine the involvement of the abdominal muscles when the pelvic floor muscles contract based on the abdominal electromyography signal.

[0070] In some optional embodiments, the pelvic floor pressure detection device includes a bladder 3 and a biofeedback module 4. The bladder 3 is used to sense the pelvic floor muscle pressure of the test subject. The biofeedback module 4 is connected to the bladder 3 and the controller, respectively. The biofeedback module 4 is used to detect the pressure generated by the deformation of the bladder 3 and convert it into a pelvic floor muscle pressure signal, and then feed the pelvic floor muscle pressure signal back to the controller. Furthermore, the bladder 3 of the pelvic floor pressure detection device is made of a non-conductive elastic material. During training, the bladder 3 is installed at the perineum of the training subject to monitor the training subject's pelvic floor muscle pressure signal in real time, thereby further ensuring the objectivity and accuracy of the pelvic floor muscle assessment.

[0071] In some optional embodiments, the magnetic stimulation output device includes a magnetic stimulation coil 5 and a magnetic stimulation control module 6. The magnetic stimulation control module 6 is connected to the magnetic stimulation coil 5, and the magnetic stimulation control module 6 is used to output a pulse current to enable the magnetic stimulation coil 5 to generate an electromagnetic pulse.

[0072] Specifically, the controller is connected to the magnetic stimulation output device, the pelvic floor pressure detection device, and the abdominal myoelectric detection device. The controller is configured to: receive pelvic floor muscle pressure signals collected by the pelvic floor pressure detection device and abdominal myoelectric signals collected by the abdominal myoelectric detection device; determine the target engagement of the abdominal muscles during pelvic floor muscle contraction based on the correlation between the pelvic floor muscle pressure signals and the abdominal myoelectric signals; and output corresponding prompt information based on the target engagement.

[0073] The pelvic floor muscle training system provided in this embodiment is configured with an abdominal electromyography detection device, and a controller receives the pelvic floor muscle pressure signal collected by the pressure detection device and the abdominal electromyography signal collected by the abdominal electromyography detection device, so as to determine the target engagement of the abdominal muscles during pelvic floor muscle contraction based on the correlation between the pelvic floor muscle pressure signal and the abdominal electromyography signal, and thus output corresponding prompt information based on the target engagement. Therefore, during the training process, when excessive abdominal muscle exertion is detected, corresponding prompt information can be output to prevent the test subject from overusing the abdominal muscles to assist the pelvic floor muscles in exerting force, and to prevent the abdominal muscles from interfering with the measurement of pelvic floor muscle strength, thereby improving the accuracy of pelvic floor muscle strength measurement.

[0074] It can be understood that the pelvic floor muscle training system of this embodiment avoids the use of vaginal electrodes or other invasive probes commonly used in traditional pelvic floor rehabilitation training through an in vitro biofeedback training method with abdominal electromyography monitoring. The training subjects do not need to endure discomfort and can train while wearing clothes, which improves the comfort and convenience of pelvic floor muscle training. At the same time, by monitoring the pelvic floor muscle pressure signals and abdominal electromyography signals, and analyzing the target participation of the abdomen during pelvic floor muscle contraction, corresponding prompt information is output according to the target participation. Therefore, the working parameters of the magnetic stimulation output device can be adjusted according to the participation of the abdominal muscles during pelvic floor muscle contraction of different training subjects, thereby improving the individualization and pertinence of the training effect.

[0075] In some optional embodiments, the controller is used to determine the target engagement of the abdominal muscles during pelvic floor muscle contraction based on the correlation between the pelvic floor muscle pressure signal and the abdominal electromyography signal, including: the controller is used to obtain a pelvic floor muscle pressure waveform and an abdominal electromyography waveform based on the pelvic floor muscle pressure signal and the abdominal electromyography signal; the controller is used to analyze the pelvic floor muscle pressure waveform to determine the pelvic floor muscle contraction area in the pelvic floor muscle pressure waveform; the controller is used to determine the abdominal muscle contraction area corresponding to the abdominal electromyography waveform based on the pelvic floor muscle contraction area; the controller is used to obtain the target engagement based on the correlation between the pelvic floor muscle pressure signal in the pelvic floor muscle contraction area and the abdominal electromyography signal in the abdominal muscle contraction area.

[0076] It should be noted that the target participation is calculated during the training of the pelvic floor muscles.

[0077] In the pelvic floor muscle training system provided by this embodiment, the controller first analyzes the generated pelvic floor muscle pressure waveform to determine the pelvic floor muscle contraction area in the pelvic floor muscle pressure waveform, and then determines the abdominal muscle contraction area corresponding to the generated abdominal electromyography waveform based on the pelvic floor muscle contraction area, so as to avoid interference of the abdominal muscle force when the pelvic floor muscles are relaxed with the judgment of the abdominal muscle participation. Therefore, based on the correlation between the pelvic floor muscle pressure signal in the pelvic floor muscle contraction area and the abdominal electromyography signal in the abdominal muscle contraction area, the target participation of the abdominal muscles when the pelvic floor muscles are contracted can be accurately obtained.

[0078] Furthermore, the controller is configured to analyze the pelvic floor muscle pressure waveform and determine a pelvic floor muscle contraction region in the pelvic floor muscle pressure waveform, including: the controller determining the pelvic floor muscle contraction region in the pelvic floor muscle pressure waveform based on a target data point in the pelvic floor muscle pressure waveform. Specifically, the target data point is the start and end points of the pelvic floor muscle contraction.

[0079] Exemplarily, when the assessment begins, abdominal electromyographic signals and pelvic floor muscle pressure signals are received. A contraction template for guiding the training subject to contract the pelvic floor muscles is displayed on the interface of the display device, and the training subject controls the contraction of the pelvic floor muscles according to voice and / or graphic and / or text instructions. The last point of the contraction template on each screen is a template node. When the collected pelvic floor muscle pressure waveform does not reach the template node, the pelvic floor muscle pressure signal continues to be acquired and the pelvic floor muscle pressure waveform is drawn. When the pelvic floor muscle pressure waveform reaches the position of the template node, all cached pelvic floor muscle pressure signals are taken out to calculate the target data point of the pelvic floor muscle pressure waveform. If no significant target data point is found, that is, there is no change caused by pelvic floor muscle contraction in the pelvic floor muscle pressure waveform, the default maximum muscle strength value is directly used as the current maximum muscle strength value. According to the target data point of the pelvic floor muscle pressure waveform, the entire pelvic floor muscle pressure waveform can be divided into a pelvic floor muscle relaxation area and a pelvic floor muscle contraction area, and the pelvic floor muscle pressure signals in the pelvic floor muscle contraction area can be distinguished according to the different areas where the data is located. and pelvic floor muscle pressure signals in relaxed areas of the pelvic floor

[0080] Specifically, during actual training, a pelvic floor pressure detection device and an abdominal electromyography detection device are mounted on a training belt. The training subject wears the training belt so that the pelvic floor pressure detection device and the abdominal electromyography detection device fit the training subject's abdomen and perineum, respectively. After donning the belt, the system is activated, and the magnetic stimulation output device and an in vitro biofeedback training device 7 based on the pelvic floor pressure detection device and the abdominal electromyography detection device are connected. The pelvic floor muscle training system is initialized, and the training subject provides personal information and training requirements. The training subject begins training, and the magnetic stimulation output device initiates magnetic stimulation training. The pelvic floor pressure detection device monitors the training subject's pelvic floor muscle pressure signal in real time. The bladder 3 of the pelvic floor pressure detection device converts muscle contraction in the perineum into compression of the bladder 3, causing pressure changes within the bladder 3. The pressure detection module can measure the current pressure data in real time. After the controller reads the data from the pressure detection module, it converts it into a pelvic floor muscle pressure signal that can be used by the controller, thereby displaying the pelvic floor muscle pressure signal in real time.

[0081] In some optional embodiments, the controller is used to obtain the target engagement based on the correlation between the pelvic floor muscle pressure signal in the pelvic floor muscle contraction area and the abdominal electromyographic signal in the abdominal muscle contraction area, including: the controller is used to determine the correlation between the pelvic floor muscle pressure signal in the pelvic floor muscle contraction area and the abdominal electromyographic signal in the abdominal muscle contraction area; the controller is used to determine the target engagement based on the correlation and the abdominal electromyographic signal in the abdominal muscle contraction area.

[0082] The pelvic floor muscle training system provided in this embodiment first determines the correlation between the pelvic floor muscle pressure signal in the pelvic floor muscle contraction area and the abdominal electromyographic signal in the abdominal muscle contraction area, and then processes the abdominal electromyographic signal in the abdominal muscle contraction area based on the correlation. Therefore, it is possible to quickly determine the target engagement of the abdominal muscles during pelvic floor muscle contraction.

[0083] Specifically, when the pelvic floor muscles contract, the abdominal electromyography detection device can also collect abdominal electromyography signals. Calculate pelvic floor muscle pressure signals during pelvic floor muscle contraction and abdominal electromyographic signals The correlation coefficient (i.e. the correlation between the two) is used to determine the involvement of the abdominal muscles. This correlation coefficient reflects whether the abdominal electromyographic signal will have the same changes as the pelvic floor muscle pressure signal, that is, whether the abdominal muscles are involved in the contraction of the pelvic floor muscles.

[0084] In some optional embodiments, the controller is used to determine the target engagement based on the correlation and the abdominal electromyographic signals in the abdominal muscle contraction area, including: the controller is used to analyze the waveform in the abdominal muscle contraction area to determine the abdominal electromyographic signals corresponding to the contraction peaks in the abdominal muscle contraction area; the controller is used to calculate the engagement of the abdominal muscles corresponding to each contraction peak based on the correlation and the abdominal electromyographic signals corresponding to each contraction peak in the contraction area; the controller is used to obtain the target engagement based on the average of all engagements.

[0085] The pelvic floor muscle training system provided in this embodiment first determines the abdominal EMG signals corresponding to the contraction peaks within the abdominal muscle contraction area. Based on the correlation between the contraction peaks within the contraction area and the abdominal EMG signals, the system calculates the degree of abdominal muscle engagement corresponding to each contraction peak, and then determines the target degree of engagement based on the average of the contraction peaks. This allows for a comprehensive determination of the abdominal muscle engagement during pelvic floor muscle contraction, preventing the influence of individual detection errors or brief abdominal muscle exertion on the determination of abdominal muscle engagement.

[0086] Specifically, the target engagement is calculated according to the following formula: Among them, E precent is the target participation, m is the number of pelvic floor muscle pressure signals within the pelvic floor muscle contraction area, is the abdominal electromyographic signal in the abdominal muscle contraction area, ρ i Pelvic floor muscle pressure signal and abdominal electromyographic signals The correlation coefficient of g(x,y) is used to characterize the method of obtaining the participation of the abdominal muscles at any contraction peak. is the pelvic floor muscle pressure signal in the pelvic floor muscle contraction area, and f(x,y) is used to represent the pelvic floor muscle pressure signal and abdominal electromyographic signals A method for determining the correlation (i.e., correlation coefficient) between two sets of data may be a commonly used correlation coefficient calculation method, where x and y are used to represent parameter variables in the calculation process.

[0087] It should be noted that the target participation value range is [0,1]. The closer the target participation value is to 1, the higher the correlation between the pelvic floor muscle pressure signal and the abdominal electromyographic signal when the pelvic floor muscle contracts, that is, the more the abdominal muscles are involved when the pelvic floor muscle contracts; the closer the target participation value is to 0, the more the pelvic floor muscle contracts, which mainly relies on the pelvic floor muscles to exert force, and the abdominal muscles are less involved.

[0088] In some optional implementations, the controller is configured to output corresponding prompt information based on the target engagement, including: if the target engagement is greater than a preset threshold, the controller is configured to output prompt information.

[0089] In the pelvic floor muscle training system provided in this embodiment, the controller is configured to output a prompt message when the target engagement level exceeds a preset threshold. Therefore, interference with the pelvic floor muscles caused by excessive abdominal muscle engagement can be avoided, thereby ensuring accurate pelvic floor muscle strength measurement.

[0090] In addition, when the target participation is greater than the preset threshold, the controller is used to output prompt information, which can also assist the training subject to complete the correct and standardized pelvic floor muscle contraction movement, helping to improve the contraction strength of the pelvic floor muscles and the participation of synergistic muscles, thereby enhancing the training effect.

[0091] In some optional embodiments, the system includes a prompt device connected to the controller, and the prompt device is used to output prompt information through text and / or graphics and / or voice.

[0092] The pelvic floor muscle training system provided in this embodiment is provided with a prompting device for outputting prompt information through text and / or graphics and / or voice, so that the training subject can timely understand the current engagement status of the abdominal muscles.

[0093] In some optional embodiments, the controller is also used to obtain the current maximum muscle strength value corresponding to the current adjustment cycle of the pelvic floor muscle contraction based on the waveform characteristics corresponding to the pelvic floor muscle contraction area; the controller is used to obtain the historical maximum muscle strength value corresponding to the previous adjustment cycle; the controller is used to determine the current pelvic floor muscle pressure threshold based on the historical maximum muscle strength value and the current maximum muscle strength value, and the current pelvic floor muscle pressure threshold is used to determine the triggering conditions of the magnetic stimulation output device.

[0094] It should be noted that the current pelvic floor muscle pressure threshold is dynamically adjusted during pelvic floor muscle training. In addition, each adjustment cycle can be regarded as the duration of the pelvic floor muscle pressure waveform corresponding to each screen contraction template.

[0095] In the pelvic floor muscle training system provided in this embodiment, the controller determines the current maximum muscle force value corresponding to the current adjustment cycle when the pelvic floor muscles are contracted based on the waveform characteristics of the pelvic floor muscle contraction area, and obtains the historical maximum muscle force value corresponding to the previous adjustment cycle to determine the current pelvic floor muscle pressure threshold, thereby automatically adjusting the triggering conditions of the magnetic stimulation output device to ensure the accuracy of the pelvic floor muscle pressure threshold. Therefore, during the training process, the triggering conditions of the magnetic stimulation output device can be made to be more in line with the actual training situation of the training subject, avoiding the problem of the initial maximum muscle force value being too large resulting in no stimulation or the initial maximum muscle force value being too small resulting in stimulation without the pelvic floor muscles being contracted forcefully.

[0096] It should be noted that after the entire pelvic floor muscle pressure waveform is divided into the pelvic floor muscle relaxation area and the pelvic floor muscle contraction area, the pelvic floor muscle pressure signal in the pelvic floor muscle contraction area can be obtained. and pelvic floor muscle pressure signals in relaxed areas of the pelvic floor Then, the maximum muscle strength value of the pelvic floor muscle contraction area and the baseline muscle strength value of the pelvic floor muscle relaxation area can be calculated according to the following formula: Among them, p Max is the maximum muscle force value, G(x) is used to characterize the algorithm for calculating the maximum muscle force value based on the waveform characteristics of the pelvic floor muscle contraction area, p base is the baseline muscle strength value, and F(x) is used to characterize the algorithm for calculating the baseline muscle strength value based on the waveform characteristics of the pelvic floor muscle relaxation area. The pelvic floor muscle will contract multiple times during the contraction phase, and p Max is the mean maximum muscle strength corresponding to each contraction phase of the pelvic floor muscles.

[0097] Specifically, during the training process, since there is no historical maximum muscle strength value in the first adjustment period, the maximum muscle strength value p of the first adjustment period is obtained after the contraction of the first screen is completed. Max and the reference pressure value p base , the pelvic floor muscle pressure threshold is calculated according to the following formula: p threshold =H(p Max ,p base ); where H(x,y) is a method for adjusting the pelvic floor muscle pressure threshold. This method finds the pelvic floor muscle pressure threshold based on the input maximum and minimum muscle force values ​​(i.e., the baseline muscle force value in the pelvic floor muscle relaxation area). When the muscle force value during pelvic floor muscle contraction (i.e., the value of the pelvic floor muscle pressure signal) reaches the pelvic floor muscle pressure threshold, magnetic stimulation begins according to the specified magnetic stimulation parameters. During subsequent training, each time the pelvic floor muscle contraction triggers magnetic stimulation, the current maximum muscle force value p' corresponding to the current adjustment cycle will be calculated using the same algorithm. Max After stimulation, the current pelvic floor muscle pressure threshold is recalculated according to the following formula: p' threshold =H(p′ Max ,p base). That is, according to the current maximum muscle strength value p' Max The pelvic floor muscle pressure threshold is recalculated based on the characteristics related to the current baseline muscle strength value.

[0098] In some optional embodiments, the pelvic floor muscle training system includes a first working mode and a second working mode. The second working mode is subsequent to the first working mode, and the controller is also used to obtain the target maximum muscle force value when the pelvic floor muscles contract in the first working mode; the controller is used to obtain the spacing adjustment coefficient corresponding to each working parameter of the magnetic stimulation output device; the controller is used to determine the various working parameters of the magnetic stimulation output device in the second working mode based on the target maximum muscle force value and the spacing adjustment coefficient corresponding to each pulse parameter.

[0099] It should be noted that, in the first working mode, each contraction stage corresponds to a maximum muscle strength value, and the target maximum muscle strength value is the average of the maximum muscle strength values ​​corresponding to each contraction stage in the first working mode.

[0100] In the pelvic floor muscle training system provided in this embodiment, the controller determines the various operating parameters of the magnetic stimulation output device in the second operating mode based on the target maximum muscle force value during pelvic floor muscle contraction in the first operating mode and the spacing adjustment coefficients corresponding to the various operating parameters of the magnetic stimulation output device. Therefore, the accuracy of adjusting the various operating parameters of the pelvic floor muscle training system can be improved, so that the various operating parameters of the magnetic stimulation output device in the second operating mode are consistent with the actual conditions of the training subject, thereby achieving better pelvic floor muscle training results.

[0101] Specifically, the first working mode is the evaluation mode, and the second working mode is the training mode. After the evaluation is completed, the target maximum muscle strength value during the evaluation process will be saved. Different working parameters will have corresponding spacing adjustment coefficients, such as: frequency spacing adjustment coefficient ρ freq , stimulation time interval adjustment coefficient ρ time In addition, the intensity spacing adjustment coefficient ρ can be set according to the actual situation strength Then, according to the interval adjustment coefficient of each working parameter and the target maximum muscle strength value, the working parameters of the magnetic stimulation output device in the training mode are determined. For example, taking the working parameter as frequency, the frequency of the electromagnetic pulse generated by the magnetic stimulation output device in the training mode is calculated according to the following formula: F = B (p Max-evaluate ,ρ freq ); where B(x,y) is used to characterize the method of calculating frequency, p Max-evaluateis the target maximum muscle strength value. Therefore, the corresponding frequency parameters can be dynamically adjusted based on the change in maximum muscle strength to ensure they are consistent with the subject's current condition, thereby achieving optimal training results. It should be noted that B(x,y) can calculate the required parameters, such as intensity and stimulation duration, based on the calculation parameter type and the selected training program type.

[0102] It should be noted that before the initial training of the pelvic floor muscle training system, a relatively long assessment of the pelvic floor muscles is conducted based on a relatively complete assessment template, so that the various working parameters of the magnetic stimulation output device can be intelligently adjusted according to the assessment results before the initial training. In addition, before each training session, a shorter assessment of the pelvic floor muscles is also conducted, and the various working parameters of the stimulation output device are adjusted based on the assessment results before each training session. The pelvic floor muscle pressure threshold is adjusted during the training process. Because a training cycle is relatively long, such as one month, the pelvic floor muscle pressure threshold can be intelligently adjusted during subsequent training sessions based on the real-time monitored pelvic floor muscle pressure signal and abdominal electromyography signal, thereby optimizing the magnetic stimulation training effect and ensuring that the pelvic floor muscle force is standardized.

[0103] In some optional embodiments, the controller is also used to: obtain the current working sub-mode of the pelvic floor muscle training system to determine the target muscle strength reference value corresponding to the current working sub-mode, the current working sub-mode being one of the sub-modes included in the first working mode and the second working mode; process the maximum muscle strength value during pelvic floor muscle contraction based on the target muscle strength parameter value to obtain a pelvic floor muscle contraction score; and generate pelvic floor muscle contraction feedback information based on the pelvic floor muscle contraction score.

[0104] It should be noted that the pelvic floor muscle contraction score is calculated in both the first and second operating modes. The pelvic floor muscle contraction score is primarily calculated in the first operating mode (i.e., the assessment mode) to generate corresponding pelvic floor muscle contraction feedback information. The generated pelvic floor muscle contraction feedback information may or may not be displayed on the display page and / or in the report, and this is not specifically limited here.

[0105] In the pelvic floor muscle training system provided in this embodiment, the controller processes the maximum muscle force value during pelvic floor muscle contraction based on the target muscle force reference value corresponding to the current operating submode to obtain a pelvic floor muscle contraction score, thereby generating corresponding pelvic floor muscle contraction feedback information. This allows for timely understanding of the subject's actual pelvic floor muscle contraction status, enabling the system to adjust its operating state accordingly and ensure the accuracy of parameter adjustment in the pelvic floor muscle training system.

[0106] Specifically, in actual operation, the pelvic floor muscle training system is pre-configured with several pressure difficulty settings and custom pressure difficulty settings. Each pressure difficulty corresponds to a working sub-mode and a corresponding muscle strength reference value. After obtaining the target muscle strength reference value corresponding to the current working sub-mode, the maximum muscle strength value during pelvic floor muscle contraction is processed according to the following formula to obtain the pelvic floor muscle contraction score: S max =h(p Max ,p edge ); where S max is the pelvic floor muscle contraction score, p Max is the maximum muscle strength of the pelvic floor muscles during contraction, p edge is the target muscle strength reference value, and h(x,y) represents the algorithm used in the working submode to calculate the pelvic floor muscle contraction score using the muscle strength reference value and the maximum muscle strength value. Specifically, the pelvic floor muscle contraction score ranges from [0,100], with higher scores indicating better pelvic floor muscle contraction.

[0107] In some optional embodiments, the controller is also used to calculate the average of the maximum muscle force values ​​during a single contraction of the pelvic floor muscles to obtain the average maximum muscle force; the controller is used to analyze the degree of muscle weakening during pelvic floor muscle contraction based on the average maximum muscle force to obtain pelvic floor muscle fatigue; the controller is used to generate pelvic floor muscle fatigue feedback information based on the pelvic floor muscle fatigue.

[0108] It should be noted that pelvic floor muscle fatigue is calculated in both the first and second operating modes. The pelvic floor muscle fatigue calculated in the first operating mode is primarily used to generate a corresponding pelvic floor muscle fatigue assessment report, while the pelvic floor muscle fatigue calculated in the second operating mode is primarily used to adjust parameters. For example, in actual operation, the magnetic stimulation output device can be controlled to operate or stop based on pelvic floor muscle fatigue, such as stopping the magnetic stimulation output device when the pelvic floor muscles are fatigued.

[0109] In the pelvic floor muscle training system provided in this embodiment, the controller analyzes the degree of muscle weakening during pelvic floor muscle contraction based on the average maximum muscle force during a single pelvic floor muscle contraction, determines pelvic floor muscle fatigue, and generates pelvic floor muscle fatigue feedback information. This allows timely understanding of the subject's pelvic floor muscle fatigue and accurate adjustment of the pelvic floor muscle training system's operating state.

[0110] Specifically, the pelvic floor muscles will contract multiple times during the contraction phase. Each contraction of the pelvic floor muscles corresponds to the average maximum muscle force. The pelvic floor muscle fatigue is then calculated according to the following formula: Among them, F is the fatigue of the pelvic floor muscles, and A(x) is used to characterize the method of calculating the degree of muscle weakening during each contraction of the pelvic floor muscles. The pelvic floor muscle fatigue value is the average value of the maximum muscle force during a single contraction of the pelvic floor muscles. It should be noted that pelvic floor muscle fatigue reflects the degree of weakening of pelvic floor muscle contraction. The normal range of pelvic floor muscle fatigue values ​​is [0.8, 1.2]. The closer the pelvic floor muscle fatigue value is to 1, the better the consistency of the training subject's pelvic floor muscle contraction. Pelvic floor muscle fatigue values ​​that are too large or too small indicate that the training subject's pelvic floor muscle contraction is more unstable, possibly indicating that the previous pelvic floor muscle contraction was too strong or too weak.

[0111] In some optional embodiments, the system includes a display device connected to a controller, and the controller is further used to obtain a current pelvic floor muscle pressure waveform corresponding to a current display page of the display device; the controller is further used to determine the pelvic floor muscle relaxation area in the current pelvic floor muscle pressure waveform, and the pelvic floor muscle relaxation area is other areas in the current pelvic floor muscle pressure waveform except the pelvic floor muscle contraction area; the controller is used to obtain a baseline muscle strength value based on the pelvic floor muscle pressure waveform characteristics corresponding to the pelvic floor muscle relaxation area; the controller is used to obtain the maximum muscle force value of the pelvic floor muscle contraction corresponding to the current pelvic floor muscle pressure waveform based on the waveform characteristics corresponding to the pelvic floor muscle contraction area in the current pelvic floor muscle pressure waveform; the controller is used to determine the coordinate axis height corresponding to the current page based on the maximum muscle force value, the baseline muscle force value and the preset redundant height corresponding to the current pelvic floor muscle pressure waveform; the controller is used to display the current pelvic floor muscle pressure waveform on the current page based on the coordinate axis height.

[0112] In the pelvic floor muscle training system provided in this embodiment, the controller determines the coordinate axis height corresponding to the current page based on the maximum muscle force value of the pelvic floor muscle contraction corresponding to the current pelvic floor muscle pressure waveform, the baseline muscle force value corresponding to the pelvic floor muscle relaxation, and a preset redundant height, and dynamically adjusts the current page to display the current pelvic floor muscle pressure waveform. This ensures that the entire pelvic floor muscle pressure waveform is within the display device's screen area, providing real-time feedback of a complete pelvic floor muscle pressure signal.

[0113] Specifically, the coordinate axis height corresponding to the current page is calculated according to the following formula: height =p Max -p base +θ,θ∈R+; where p height is the coordinate axis height corresponding to the current page, p Max is the maximum muscle strength of the pelvic floor muscles during contraction, p base is the baseline muscle strength value of the pelvic floor muscle relaxation area, θ is the preset redundancy height of the coordinate axis, and R+ is a set of positive real numbers. Specifically, the preset redundancy height can be set according to user habits, and its specific value is not limited here.

[0114] It should be noted that, whether it is the evaluation process or the training process of magnetic stimulation, the coordinate axis height corresponding to the current page will be calculated based on the calculated maximum muscle strength value and the baseline muscle strength value. After each screen template is completed, the coordinate axis height will be recalculated and changed to ensure that the waveform display is complete, so that the training subject can complete the training.

[0115] Understandably, during magnetic stimulation training, the high-intensity, changing magnetic field generated by the device stimulates the pelvic floor muscles to achieve a training effect. However, due to the eddy current effect, the metal parts on the conventional vaginal electrodes will produce a thermal effect, and the metal parts will reach a high temperature that is difficult for people to accept in a short period of time. Therefore, pelvic floor muscle strength detection methods with metal parts are difficult to apply to real-time muscle strength detection and analysis in magnetic stimulation training. Therefore, magnetic stimulation output devices rarely include active training modules. Some are equipped with a biofeedback module 4 for training, which also only has a single-channel fluid sensing perineal pressure change, making it impossible to distinguish between synergistic muscle interference and thus unable to determine whether the pelvic floor muscle force is normal. Therefore, in the pelvic floor muscle training system of the present invention, a pelvic floor pressure detection device and an abdominal electromyography detection device are introduced. By monitoring the pelvic floor muscle pressure signal and the abdominal electromyography signal, combined with intelligent algorithm analysis, it is possible to accurately assess the pelvic floor muscle function and generate a personalized magnetic stimulation training program based on individual differences. During the use of the pelvic floor muscle training system provided by this embodiment, the use of vaginal electrodes can be avoided, providing a more comfortable and convenient training experience.

[0116] At the same time, in the related art, most of the working parameters of the pelvic floor muscle training system are manually adjusted through external feedback from the detection object or pelvic floor electrical equipment and the operator's experience. They lack intelligent adjustment functions and cannot dynamically adjust the training parameters according to the actual situation of the training object, resulting in low accuracy of parameter adjustment of the pelvic floor muscle training system and insufficient precision and effectiveness of the training effect. In contrast, the pelvic floor muscle training system of the present invention can adjust magnetic stimulation parameters such as the pelvic floor muscle pressure threshold, the frequency of the electromagnetic pulse, and the stimulation time in real time to improve the accuracy of parameter adjustment of the pelvic floor muscle training system, optimize the training effect, and effectively improve the training effect. Not only that, through real-time monitoring and data recording, relevant personnel can also comprehensively track and evaluate the training progress of the training object, providing strong support for the personalized adjustment of the training plan.

[0117] In some optional embodiments, the pelvic floor muscle training system further includes an external biofeedback training device 7; wherein the pelvic floor pressure detection device and the abdominal electromyography detection device are respectively connected to the external biofeedback training device 7, and the external biofeedback training device 7 is connected to the magnetic stimulation output device, thereby forming a complete pelvic floor muscle training system. A controller and a display device are provided on the external biofeedback training device 7, and are used to process the collected pelvic floor muscle pressure signals and abdominal electromyography signals and display the training status in real time. The pelvic floor muscle pressure signals, abdominal electromyography signals, and data records monitored in real time by the external biofeedback training device 7 enable relevant personnel to comprehensively track and evaluate the training progress of the training subject, helping to guide the adjustment of the training plan and further optimize the training effect. Specifically, during the operation of the pelvic floor muscle training system, the abdominal electromyography detection device collects abdominal electromyography signals, and the pelvic floor muscle pressure detection device collects pelvic floor muscle pressure signals. Then, the abdominal electromyography signals collected by the abdominal electromyography detection device and the pelvic floor muscle pressure signals collected by the pelvic floor pressure detection device are fed back to the in vitro biofeedback training device 7. The controller in the in vitro biofeedback training device 7 processes the abdominal electromyography signals and the pelvic floor muscle pressure signals to generate corresponding feedback information (such as prompt information, pelvic floor muscle contraction feedback information, pelvic floor muscle fatigue feedback information, etc.) or control information, and sends the feedback information to the corresponding prompt device, display device or user equipment, and sends the control information to the magnetic stimulation output device so that the magnetic stimulation output device generates electromagnetic pulses according to the control information.

[0118] For example, see Figure 2The working process of the pelvic floor muscle training system includes the following steps: Step S11, obtaining the pelvic floor muscle pressure signal and the abdominal electromyography signal. Step S12, judging whether the training process is over, if so, executing step S13, otherwise executing step S14. Step S13, stopping collecting the pelvic floor muscle pressure signal and the abdominal electromyography signal, and the process ends. Step S14, judging whether the pelvic floor muscle pressure waveform reaches the template node, if so, executing step S16, otherwise executing step S15. Step S15, drawing the pelvic floor muscle pressure waveform and the abdominal electromyography waveform, and then returning to step S11. Step S16, finding the starting and ending points of the pelvic floor muscle contraction to obtain the target data point. Step S17, judging whether there is a target data point, if so, executing step S18, otherwise executing step S15. Step S18, calculating the parameters. Specifically, in the evaluation stage, the calculation parameters can be the maximum muscle strength value when the pelvic floor muscles are contracted, the baseline muscle strength value when the pelvic floor muscles are relaxed, the target engagement of the abdominal muscles when the pelvic floor muscles are contracted, the pelvic floor muscle contraction score, the pelvic floor muscle fatigue, and the coordinate axis height of the current page of the display device; in the treatment stage, in addition to the maximum muscle strength value when the pelvic floor muscles are contracted, the baseline muscle strength value when the pelvic floor muscles are relaxed, the target engagement of the abdominal muscles when the pelvic floor muscles are contracted, the pelvic floor muscle contraction score, the pelvic floor muscle fatigue, and the coordinate axis height of the current page of the display device, the calculation parameters can also be the calculation of the current pelvic floor muscle pressure threshold. Step S19, update the interface display. Specifically, according to the different stages of the pelvic floor muscle training system, the corresponding content is displayed.

[0119] It is worth noting that, in actual operation, the pelvic floor muscle training system operates as follows: 1. The pelvic floor pressure detection device monitors and collects the trainee's pelvic floor muscle pressure signals in real time. 2. The abdominal electromyography detection device monitors and collects the trainee's abdominal electromyography signals in real time. 3. Before training begins, the pelvic floor muscle training system comprehensively analyzes and evaluates the pelvic floor muscle pressure and abdominal electromyography signals to determine the contraction of the pelvic floor muscles. 4. Based on the evaluation results of pelvic floor muscle contraction in step 3, a personalized magnetic stimulation training plan is generated to adjust the operating parameters of the magnetic stimulation output device, such as the frequency and duration of magnetic stimulation. Parameters such as the intensity and pulse width of magnetic stimulation can also be adjusted by the user or automatically. 5. During training, the pelvic floor muscle pressure threshold is dynamically adjusted based on the real-time monitored pelvic floor muscle pressure and abdominal electromyography signals. This adjustment controls the output of magnetic stimulation to optimize the training effect and ensure proper pelvic floor muscle application. 6. During training, if the abdominal muscles are over-engaged, the pelvic floor muscle training system will provide intelligent prompts to the trainee to prevent interference with the pelvic floor muscles. Furthermore, during training, the pelvic floor muscle training system records and stores the trainee's pelvic floor muscle pressure signals and abdominal electromyography signals in real time until the end of the training. The trainee or relevant personnel can review the training effect report and data records, and relevant personnel can also adjust the training plan through data analysis.

[0120] In addition, in actual operation, the magnetic stimulation parameters can be adjusted in combination with the training progress of the training subject. By analyzing the historical data and training progress of the training subject's pelvic floor muscle pressure signals and abdominal electromyography signals, the pelvic floor muscle training system intelligently adjusts the magnetic stimulation parameters (such as: electromagnetic pulse frequency, stimulation time, etc.) to achieve the adjustment of the pelvic floor muscle magnetic stimulation training plan as the training progress changes.

[0121] It should be noted that in addition to combining abdominal electromyographic signals to assist in the assessment of pelvic floor muscle function, other signals can also be combined to assist in the assessment of pelvic floor muscle function and generate intelligent solutions. For example, the surface electromyographic signals of the pelvic floor muscles can be collected or other non-invasive sensing technologies such as ultrasound can be used. Through the monitoring and analysis of these signals, the pelvic floor muscle training system can still accurately assess the pelvic floor muscle function to adjust the training plan or the working parameters of the magnetic stimulation output device. Not only that, the controller can also use machine learning algorithms to process training data, including pelvic floor muscle pressure signals and abdominal electromyographic signals. By training a large amount of training data, the pelvic floor muscle training system can establish an intelligent model to more accurately predict the optimal setting values ​​of the magnetic stimulation parameters.

Such modifications and variations are all within the scope defined by the appended claims.
