Low-energy pulsed electromagnetic field (PEMF) therapy has been suggested as a promising therapy to increase microcirculation, which is of great concern in patients with fibromyalgia. This study evaluated the effectiveness of PEMF therapy on the treatment of fibromyalgia. A group of 108 women with fibromyalgia were allocated to a 12-week treatment period with an active Bio-Electro-Magnetic-Energy-Regulation (BEMER) device and a similar treatment period with an inactive device. Each patient received active and sham treatments in a random order. Pain and stiffness were assessed on a visual analog scale (VAS, scale 0-100 mm), and functional status was assessed by the Fibromyalgia Impact Questionnaire (FIQ). Mean VAS pain scores before the active and sham treatment periods were 66 (SD 22) and 63 (SD 22), respectively. After treatment periods, mean VAS pain scores had decreased significantly in active treatment, -12, 95% CI [-18, -6], and in sham treatment, -11, 95% CI [-17, -5]. Similarly, the decrease in stiffness and FIQ index after both treatments was statistically significant. However, per-protocol analysis showed no differences between active and sham treatments at any of the outcomes. This study demonstrated that low-energy PEMF therapy was not efficient in reducing pain and stiffness or in improving functioning in women with fibromyalgia.

脉冲电磁场​​疗法治疗纤维肌痛的疼痛和其他症状：一项随机对照研究。

低能量脉冲电磁场​​（PEMF）治疗被认为是增加微循环的有前途的治疗方法，这在纤维肌痛患者中引起了极大的关注。这项研究评估了PEMF治疗纤维肌痛的疗效。一组108名患有肌纤维痛的妇女被分配为使用主动生物电磁能量调节（BEMER）装置的12周治疗期，而使用不活跃装置的类似治疗期。每位患者均以随机顺序接受主动治疗和假治疗。在视觉模拟量表（VAS，量表0-100 mm）上评估疼痛和僵硬，并通过纤维肌痛影响问卷（FIQ）评估功能状态。在积极和假治疗期之前，VAS的平均疼痛评分分别为66（标准差22）和63（标准差22）。经过治疗期后 在积极治疗中，-12的95％CI的平均VAS疼痛评分明显降低[-18，-6]，在假治疗中-11的95％CI的平均疼痛评分[-17，-5]。同样，两种治疗后的硬度和FIQ指数的降低在统计学上也是显着的。但是，按方案分析显示，主动治疗和假治疗在任何结果上均无差异。这项研究表明，低能量PEMF疗法不能有效减轻纤维肌痛女性的疼痛和僵硬或改善其功能。生物电磁学。39：405-413，2018.©2018 Wiley Periodicals，Inc. 方案分析显示，主动治疗和假治疗在任何结果上均无差异。这项研究表明，低能量PEMF疗法不能有效减轻纤维肌痛女性的疼痛和僵硬或改善其功能。生物电磁学。39：405-413，2018.©2018 Wiley Periodicals，Inc. 方案分析显示，主动治疗和假治疗在任何结果上均无差异。这项研究表明，低能量PEMF疗法不能有效减轻纤维肌痛女性的疼痛和僵硬或改善其功能。生物电磁学。39：405-413，2018.©2018 Wiley Periodicals，Inc.
