INTRODUCTION AND HYPOTHESIS: Patients with interstitial cystitis/bladder pain syndrome (IC/BPS) often experience chronic pelvic and even systemic pain that can be difficult to clinically manage. Pulsed electromagnetic field (PEMF) therapy, a non-invasive strategy that has shown significant efficacy for pain reduction in other chronic pain conditions, may provide benefit for pain management in patients with IC/BPS. METHODS: PEMF delivery to patients occurs via a bio-electromagnetic-energy device which consists of a flexible mat (180 × 50 cm) that the patient lies on for systemic, full-body delivery and/or a flexible pad (50 × 15 cm) for targeted delivery to a specific body region (e.g., pelvic area). The duration of individual sessions, number of sessions per day, total number of sessions, and follow-up observation period vary between previously published studies. Positive outcomes are typically reported as a significant reduction in visual analog scale (VAS) pain score and functional improvement assessed using validated questionnaires specific to the condition under study. RESULTS AND CONCLUSIONS: The use of PEMF has been evaluated as a therapeutic strategy for pain management in several clinical scenarios. Randomized, double-blinded, placebo-controlled trials have reported positive efficacy and safety profiles when PEMF was used to treat non-specific low back pain, patellofemoral pain syndrome, chronic post-operative pain, osteoarthritis-related pain, rheumatoid arthritis-related pain, and fibromyalgia-related pain. Based on these positive outcomes in a variety of pain conditions, clinical trials to evaluate whether PEMF can provide a safe, non-invasive therapeutic approach to improve symptoms of chronic pain and fatigue in patients with IC/BPS are warranted.
引言与假设:间质性膀胱炎/膀胱疼痛综合征(IC/BPS)患者常经历慢性盆腔疼痛甚至全身性疼痛,临床管理颇具难度。脉冲电磁场(PEMF)疗法是一种非侵入性策略,已在其他慢性疼痛病症中显示出显著的止痛效果,可能对IC/BPS患者的疼痛管理有益。 方法:通过生物电磁能量设备向患者输送PEMF,该设备包括一块柔性垫(180×50厘米),患者躺在上面接受全身照射,和/或一块柔性垫(50×15厘米)用于靶向照射特定身体区域(如盆腔区域)。先前发表的研究中,单次治疗时长、每日治疗次数、总治疗次数以及随访观察期各不相同。阳性结果通常表现为视觉模拟量表(VAS)疼痛评分显著降低,以及使用针对所研究病症的有效问卷评估的功能改善。 结果与结论:在几种临床情况下,已对PEMF作为疼痛管理治疗策略进行了评估。随机、双盲、安慰剂对照试验报告称,当PEMF用于治疗非特异性腰痛、髌股疼痛综合征、慢性术后疼痛、骨关节炎相关疼痛、类风湿关节炎相关疼痛和纤维肌痛相关疼痛时,具有积极的疗效和安全性。基于这些在多种疼痛病症中的积极结果,有必要开展临床试验以评估PEMF是否能为改善IC/BPS患者的慢性疼痛和疲劳症状提供一种安全、非侵入性的治疗方法。
