Abstract:

Objective To investigate the therapeutic effects of combined magnetic and electrical stimulation with an "intelligent exercise prescription" and novel matrix radiofrequency therapy in patients with pelvic organ prolapse （POP）. Methods A total of 158 patients with POP who received treatment at the Gynecological Pelvic Floor Rehabilitation Center of the Eighth Affiliated Hospital of Southern Medical University between October 2022 and July 2025 were retrospectively enrolled and divided into an observation group （n = 64） and a control group （n = 94） based on their treatment plans. The control group underwent magnetic and electrical stimulation combined with an "intelligent exercise prescription" regimen. Specifically， patients received 10 sessions of electrical stimulation， 5 sessions of magnetic stimulation， and performed 15 ~ 20 minutes of daily home exercise training guided by the "intelligent exercise prescription." The observation group received， in addition to the aforementioned treatments， four sessions of novel matrix radiofrequency therapy. Changes in the muscle strength grades of type Ⅰ and type Ⅱ pelvic floor muscles， Glazer surface electromyography （EMG） values， and POP-Q staging were compared between the two groups before and after treatment. Results After treatment， both groups demonstrated significant improvements in type Ⅰ and type Ⅱ muscle fiber strength compared to baseline （all P < 0.05）， with the observation group showing greater improvement in type Ⅰ muscle fiber strength than the control group （P < 0.05）. The muscle potential values of the observation group during rapid contraction， tense contraction， and endurance contraction stages were markedly increased compared to pre-treatment levels. Moreover， the muscle potential values during the pre-resting stage were significantly reduced after treatment （P < 0.05）. In the observation group， POP-Q grades of the anterior vaginal wall， uterus， and posterior vaginal wall were all significantly lower post-treatment than pre-treatment （all P < 0.05）. However， no statistically significant differences were observed between the observation group and the control group in these parameters （P > 0.05）. Both groups exhibited relatively high compliance rates （both ≥75.0%）， with no significant difference between them （P > 0.05）. The treatment cost for the observation group was significantly higher than that for the control group （P < 0.05）. Conclusions The combination of magneto-electrical stimulation， an "intelligent exercise prescription，" and novel matrix radiofrequency therapy can significantly improve pelvic floor muscle strength and muscle potential values in the short term， compared to pre-treatment levels. This integrated approach also effectively alleviates the prolapse of the anterior vaginal wall， uterus， and posterior vaginal wall. Furthermore， the combination of magnetic and electrical stimulation， "intelligent exercise prescription，" and matrix radiofrequency therapy demonstrates superior efficacy in enhancing type Ⅰ pelvic floor muscle fiber strength when compared to the combination of magnetic and electrical stimulation with "intelligent exercise prescription" alone. However， this treatment protocol entails a relatively high economic burden， and its clinical application should be carefully evaluated in consideration of patients’ functional needs and financial conditions.
