There was a significant negative correlation between pregnancy weight gain and pelvic floor electrophysiological (r=-0.367, P=0.000), and there was a significant positive correlation between compliance with electrical stimulation combined with biofeedback treatment and pelvic floor electrophysiological score (r=0.337, P=0.000). Weight gain during pregnancy and compliance of electrical stimulation combined with biofeedback therapy were included in the equation model of influencing factors, and the proportion of variation explanation for the equation model of influencing factors of pelvic floor muscle electrophysiological increased after the addition of compliance as an independent variable. The compliance of electrical stimulation combined with biofeedback therapy can affect the electrophysiological score of pelvic floor muscle of patients. It is suggested to improve the compliance of patients through multiple ways to delay the occurrence and development of pelvic floor dysfunction.

With the persistence of injury and the lack of timely recovery, typical symptoms of pelvic floor dysfunction (PFD) gradually emerge (Sangsawang, 2014). According to the literature, the incidence of postpartum pelvic floor electrophysiological abnormalities ranges from 47% to 95% (Huang et al., 2018; Sun et al., 2015; Yang et al., 2019). Moreover, changes in postpartum pelvic floor electrophysiology are closely associated with the onset of PFD symptoms such as stress urinary incontinence and pelvic organ prolapse (Zhang et al., 2014). Affected patients are prone to negative emotions and feelings of shame (Wang et al., 2020), experience lower psychological resilience (Dai et al., 2018), and face an increased risk of postpartum depression, significantly impacting their quality of life. Non-surgical interventions, including manual therapy and stimulation or relaxation techniques (Sigurdardottir et al., 2021), are the primary treatment options for early-stage patients. Among these, pelvic floor electrical stimulation combined with biofeedback therapy has been strongly recommended in multiple guidelines as an essential method for postpartum pelvic floor rehabilitation (Okeahialam et al., 2022; Chinese Urological Association Female Urology Group, 2023). This approach facilitates passive contraction of the pelvic floor muscles through electrical stimulation while using sensors to convert muscle activity into visual or auditory signals, making the treatment process more engaging and interactive. Patients can also personalize the electrical stimulation intensity, frequency, and biofeedback training modes based on their pelvic floor muscle condition (e.g., muscle strength and contraction response). Compliance is a key factor in the success of non-surgical pelvic floor muscle therapy (Venegas et al., 2018; Araujo et al., 2020; Reed et al., 2020; Woodburn et al., 2021; Harper et al., 2023).
