OBJECTIVE Fibromyalgia (FM) is characterized by pain and fatigue, particularly during physical activity. Transcutaneous electrical nerve stimulation (TENS) activates endogenous pain inhibitory mechanisms. This study was undertaken to investigate if using TENS during activity would improve movement-evoked pain and other patient-reported outcomes in women with FM. METHODS Participants were randomly assigned to receive active TENS (n = 103), placebo TENS (n = 99), or no TENS (n = 99) and instructed to use it at home during activity 2 hours each day for 4 weeks. TENS was applied to the lumbar and cervicothoracic regions using a modulated frequency (2-125 Hz) at the highest tolerable intensity. Participants rated movement-evoked pain (primary outcome measure) and fatigue on an 11-point scale before and during application of TENS. The primary outcome measure and secondary patient-reported outcomes were assessed at baseline (time of randomization) and at 4 weeks. RESULTS After 4 weeks, a greater reduction in movement-evoked pain was reported in the active TENS group versus the placebo TENS group (group mean difference -1.0 [95% confidence interval -1.8, -0.2]; P = 0.008) and versus the no TENS group (group mean difference -1.8 [95% confidence interval -2.6, -1.0]; P < 0.0001). A reduction in movement-evoked fatigue was also reported in the active TENS group versus the placebo TENS group (group mean difference -1.4 [95% confidence interval -2.4, -0.4]; P = 0.001) and versus the no TENS group (group mean difference -1.9 [95% confidence interval -2.9, -0.9]; P = <0.0001). A greater percentage of the patients in the active TENS group reported improvement on the global impression of change compared to the placebo TENS group (70% versus 31%; P < 0.0001) and the no TENS group (9%; P < 0.0001). There were no TENS-related serious adverse events, and <5% of participants experienced minor adverse events from TENS. CONCLUSION Among women who had FM and were on a stable medication regimen, 4 weeks of active TENS use compared to placebo TENS or no TENS resulted in a significant improvement in movement-evoked pain and other clinical outcomes. Further research is needed to examine effectiveness in a real-world setting to establish the clinical importance of these findings.

经皮电神经刺激减少运动诱发的疼痛和疲劳:一项随机对照试验。

目的 纤维肌痛 (FM) 的特点是疼痛和疲劳,尤其是在体力活动期间。经皮神经电刺激 (TENS) 激活内源性疼痛抑制机制。本研究旨在调查在活动期间使用 TENS 是否会改善 FM 女性的运动诱发疼痛和其他患者报告的结果。方法 参与者被随机分配接受活性 TENS(n = 103)、安慰剂 TENS(n = 99)或无 TENS(n = 99),并被指示在每天 2 小时的活动期间在家中使用它,持续 4 周。使用调制频率 (2-125 Hz) 在最高耐受强度下将 TENS 应用于腰椎和颈胸区域。参与者在使用 TENS 之前和期间对运动诱发的疼痛(主要结果测量)和疲劳进行了 11 点评分。在基线(随机化时)和 4 周时评估主要结果测量和次要患者报告的结果。结果 4 周后,与安慰剂 TENS 组相比,活性 TENS 组报告的运动诱发疼痛减轻更大(组均数差异 -1.0 [95% 置信区间 -1.8,-0.2];P = 0.008)和无 TENS 组(组均数差 -1.8 [95% 置信区间 -2.6,-1.0];P < 0.0001)。与安慰剂 TENS 组相比,活性 TENS 组(组均数差 -1.4 [95% 置信区间 -2.4,-0.4];P = 0.001)和无 TENS 组(组平均差 -1.9 [95% 置信区间 -2.9, -0.9];P = <0.0001)。与安慰剂 TENS 组(70% 对 31%;P < 0.0001)和无 TENS 组(9%;P < 0.0001)相比,活性 TENS 组中更大比例的患者报告对变化的整体印象有所改善。没有与 TENS 相关的严重不良事件,<5% 的参与者经历了来自 TENS 的轻微不良事件。结论 在患有 FM 并接受稳定药物治疗的女性中,与安慰剂 TENS 或不使用 TENS 相比,使用 4 周的活性 TENS 可显着改善运动诱发的疼痛和其他临床结果。需要进一步的研究来检验现实环境中的有效性,以确定这些发现的临床重要性。没有与 TENS 相关的严重不良事件,<5% 的参与者经历了来自 TENS 的轻微不良事件。结论 在患有 FM 并接受稳定药物治疗的女性中,与安慰剂 TENS 或不使用 TENS 相比,使用 4 周的活性 TENS 可显着改善运动诱发的疼痛和其他临床结果。需要进一步的研究来检验现实环境中的有效性,以确定这些发现的临床重要性。没有与 TENS 相关的严重不良事件,<5% 的参与者经历了来自 TENS 的轻微不良事件。结论 在患有 FM 并接受稳定药物治疗的女性中,与安慰剂 TENS 或不使用 TENS 相比,使用 4 周的活性 TENS 可显着改善运动诱发的疼痛和其他临床结果。需要进一步的研究来检验现实环境中的有效性,以确定这些发现的临床重要性。
