Abstract To explore the long-term therapeutic efficacy of the home-based training combined with sacral nerve magnetic stimulation (SNMS) and pelvic floor muscle rehabilitation training (PFMRT) for treating patients with chronic pelvic pain (CPP). Methods: From June 2022 to June 2023, 100 patients with CPP were selected and were divided into two groups (50 cases in each group) by random number table method. 10 patients in the control group had dropped out, so finally, 40 patients were included in the control group for analysis. The patients in the two groups received SNMS and PFMRT, and the patients in the observation group received home-based training additionally. The patients in the two groups were followed up for 6 months. The therapeutic effect, the pelvic floor muscle (PFM) strength, the situations of PFM tenderness and evaluation by Glazer surface electromyographic evaluation of pelvic floor, and the adverse reactions of the patients were compared between the groups. Results: The score (3.05±0.69 points) of the clinical global impression of improvement (CGI-I) of the patients in the observation group after treatment was significantly higher than that (2.12±0.57 points) of the patients in the control group. The PFM strength of the patients in the two groups after treatment had increased significantly. The grade by Laycock modified Oxford muscle strength classification (MOS) of the patients in the observation group was significantly better than that of the patients in the control group. The visual analogue scale (VAS) score of the patients in the two groups after treatment had decreased significantly, and which (2.84±1.06 points) of the patients in the observation group was significantly lower than that (3.65±1.44 points) of the patients in the control group. The values of the rapid contraction relaxation time, the average pre-resting electromyography and the average post-resting electromyography of the patients in the two groups after treatment had decreased significantly, and which (3.24±1.06 s, 4.83±1.45μV and 4.15±0.81μV) of the patients in the observation group were significantly lower than those (4.01±1.12 s, 5.66±1.61μV and 4.81±0.95μV) of the patients in the control group (all P<0.05). There was no any patient with obvious adverse reactions in the two groups during treatment. During the follow-up period, there was no significant difference in the CPP recurrence rate (1 case, 2.0% vs. 4 cases, 10.0%) of the patients between the two groups (Fisher's exact probability=0.167). Conclusion: Home-based training combined with SNMS and PFMRT for treating the patients with CPP has good effectiveness, which can improve their pelvic floor muscle strength and surface electromyography result, and can relieve their pain, and with the higher safety.
