研究目的:

本研究旨在通过一项三臂随机对照试验,明确比较序贯与联合两种磁电治疗模式对产后盆底功能障碍(PFD)的临床疗效优劣,为优化康复方案提供高级别循证依据。同时,通过动态监测血清骨桥蛋白(OPN)水平,解析其与盆底功能恢复的相关性,探索磁电治疗调控组织修复的潜在分子机制。  

Objectives of Study:

This study aims to conduct a three-arm randomized controlled trial to determine the comparative clinical efficacy of sequential versus combined magnetic-electrical therapy modalities for postpartum pelvic floor dysfunction (PFD), thereby providing high-level evidence-based guidance for optimizing rehabilitation protocols. Concurrently, by dynamically monitoring serum osteopontin (OPN) levels, we will elucidate its correlation with pelvic floor function recovery and explore the potential molecular mechanisms through which magnetic-electrical therapy modulates tissue repair.
