摘要

本研究旨在评估 A 型肉毒杆菌神经毒素(BoNT/A)治疗前后慢性盆底痛(CPP)患者盆底肌(PFM)两侧之间(两侧耦合)和盆底肌单侧内部(单侧耦合)的电耦合情况。在接受 BoNT/A 治疗前后(第 0、8、12、24 周),记录了 24 名 CPP 患者(P)左右两侧 PFM 的表面肌电图(sEMG)信号。同时还对 24 名健康女性(H)进行了记录。在收缩期间,通过其 sEMG 信号的交叉相关性(CC)和假想部分一致性(iCOH)评估 PFM 两侧和单侧耦合。通过比较 P(0) vs. P(8,12,24) 和 H vs. P(0,8,12,24) 来评估它们之间的显著差异。这项研究表明,治疗前各组的 PFM 双侧耦合相似,而在 BoNT/A 治疗前和治疗后,患者最疼痛一侧的 PFM 单侧耦合失常:振幅耦合(iCOH)低于健康女性。这可能是由于适应肌肉疼痛的神经运动控制策略发生了改变、PFM 的结构和电气发生了变化以及其神经支配模式发生了改变,这些可能会影响治疗后 CPP 的发生、持续或复发。

Pelvic floor muscle electrical coupling in chronic pelvic pain: Insights into pathophysiology and botulinum toxin treatment effects
This study aimed to assess the electrical coupling between both pelvic floor muscle (PFM) sides (two-sided coupling) and within individual PFM sides (one-sided coupling) in chronic pelvic pain (CPP) before and after botulinum neurotoxin type A (BoNT/A) treatment. Surface electromyographic (sEMG) signals were recorded from the left and right PFM of 24 patients (P) with CPP before and after being treated with BoNT/A (Weeks 0,8,12,24). Recordings were also made in 24 healthy women (H). PFM two-sided and one-sided coupling was evaluated during contractions by the cross-correlation (CC) and the imaginary part of coherency (iCOH) of their sEMG signals. Significant differences between their values were assessed comparing P(0) vs. P(8,12,24) and H vs. P(0,8,12,24). This study showed that PFM two-sided coupling is similar across groups before treatment, while PFM one-sided coupling on the patients’ most painful side is deranged before and also after BoNT/A treatment: amplitude coupling is lower (<CC) and phase difference is greater (>iCOH) than healthy women’s. This could be justified by altered neuromotor control strategies developed as an adaptation to muscle pain, structural and electrical changes in PFM, and alterations in their innervation pattern, which may influence the onset, perpetuation, or recurrence of CPP after treatment.
