摘要

Introduction and Hypothesis

Postpartum pelvic floor dyssynergic defecation (PFDD) is a common and distressing condition. We hypothesized that transcutaneous tibial nerve stimulation (TTNS) combined with standard rehabilitation would be superior to rehabilitation alone for alleviating symptoms in primiparous women with PFDD.

Methods

In this randomized controlled trial, 40 primiparous women with PFDD were allocated to an intervention group (TTNS + standard rehabilitation, n = 20) or a control group (sham stimulation + standard rehabilitation, n = 20). The intervention lasted 6 weeks. Primary (constipation symptom score) and secondary outcomes (clinical efficacy, pelvic floor surface electromyography) were assessed at baseline and post-treatment.

Results

Both groups improved significantly after treatment (p < 0.05). However, the intervention group demonstrated a significantly greater reduction in constipation symptom scores (p < 0.05) and a higher overall clinical effectiveness rate (90% vs. 65%, p < 0.05). Pelvic floor surface electromyography showed significantly greater improvement in the intervention group for resting, fast, and slow contraction phases (p < 0.05), but not for endurance (p > 0.05).

Conclusions

TTNS is an effective adjunct to standard rehabilitation for improving constipation symptoms and pelvic floor muscle function in primiparous women with PFDD. It represents a valuable, non-invasive therapeutic option for this condition.This study demonstrates positive effects of transcutaneous tibial nerve stimulation as an adjunctive therapy for primiparous women with postpartum pelvic floor dyssynergic defecation. It significantly improves constipation symptoms, clinical effectiveness rates, and key parameters of pelvic floor muscle function compared to standard rehabilitation alone. Given its non-invasive nature, favorable safety profile, and demonstrated clinical benefits,TTNS represents a valuable addition to the therapeutic options for this common postpartum condition.
