Clinical study on the efficacy of electroacupuncture combined with pelvic floor muscle training for female stress urinary incontinence.

BACKGROUND

To evaluate the clinical efficacy and synergistic effects of electroacupuncture (EA) combined with pelvic floor muscle training (PFMT) in the treatment of mild-to-moderate stress urinary incontinence (SUI) in women.

METHODS

A single-blind (assessor-blinded), 2 × 2 factorial, randomized controlled trial was conducted. A total of 128 SUI patients were allocated to 4 groups: the EA group (sessions every other day, targeting acupoints including Guanyuan [RN4] and Shenshu [BL23]), PFMT group (3 daily sessions), combination group (EA + PFMT), and waitlist group. The intervention lasted for 4 weeks. The primary outcome was the change in 1-hour pad test leakage volume. Secondary outcomes included 72-hour urinary incontinence episodes and International Consultation on Incontinence Questionnaire-Short Form scores. Data were analyzed using intention-to-treat and factorial analysis of variance.

RESULTS

The combination group showed the greatest reduction in leakage volume (6.17 g, 95% confidence interval [CI] = 5.89-6.44), significantly outperforming the EA group (4.53 g, 95% CI = 4.26-4.81), PFMT group (2.13 g, 95% CI = 1.85-2.41), and waitlist group (0.38 g, 95% CI = 0.11-0.66; all P < .001). Factorial analysis confirmed significant main effects for EA (mean difference = 5.35 g, 95% CI = 5.15-5.54) and PFMT (mean difference = 4.15 g, 95% CI = 3.95-4.34; both P < .001), but no interaction effect (P = .686). Secondary outcomes showed consistent improvements in incontinence episodes and International Consultation on Incontinence Questionnaire-Short Form scores.

CONCLUSION

Combined EA and PFMT significantly alleviated SUI symptoms. Although no synergy was observed, the additive therapeutic effect provided clinical benefits, offering a promising nonsurgical alternative for SUI management.
