INTRODUCTION: Strategies to reduce pharmacologic use for pain are needed. Pulsed electromagnetic field (PEMF) therapy is a noninvasive, nonpharmacologic treatment for pain that modifies nitric oxide signaling to improve healing. This study examined whether PEMF decreased pain and pharmacologic use vs. standard-of-care (SOC) treatment for joint and soft tissue pain. METHODS: This prospective, randomized controlled trial enrolled 120 patients presenting with joint or soft tissue pain at five orthopedic clinic sites. The PEMF group self-administered daily therapy from a commercially available device and the SOC group received standard treatment daily as prescribed by the clinician. Patients recorded their pain level, pharmacologic usage, and adverse events daily for 14 days. After 14 days, patients in the SOC group were given the option to crossover to PEMF therapy and continue for 16 days. The study was overseen by an independent clinical research organization. It was hypothesized that PEMF would be superior to SOC for pain management. RESULTS: PEMF treatment provided significant analgesic benefits compared to SOC. Complete data was collected for 91 patients, 48 from the PEMF group and 43 from the SOC group. The least squares mean pain score change from baseline was - 1.8 (a 36% reduction) for the PEMF group, significantly surpassing - 0.46 (a 10% reduction) for the SOC group (p < 0.0001). Pharmacologic usage decreased from 40 to 18% for the PEMF group (a 55% reduction), while the SOC group decreased from 40 to 35% (a 12% reduction). In the crossover subgroup, patients experienced an additional 18% decrease in pain score and 63% decrease in pharmacologic use after switching from SOC to PEMF treatment. CONCLUSIONS: PEMF was significantly more effective than SOC at managing pain and reducing pharmacologic use. PEMF therapy should be considered for noninvasive, nonpharmacologic management of joint and soft tissue pain. TRIAL REGISTRATION: ClinicalTrials.gov ID NCT05244187.
引言:需要采取策略减少疼痛药物的使用。脉冲电磁场(PEMF)疗法是一种用于疼痛的非侵入性、非药物治疗方法,可调节一氧化氮信号传导以促进愈合。本研究探讨了与关节和软组织疼痛的标准治疗(SOC)相比,PEMF是否能减轻疼痛并减少药物使用。 方法:这项前瞻性、随机对照试验纳入了5个骨科诊所的120例出现关节或软组织疼痛的患者。PEMF组使用市售设备自行进行每日治疗,SOC组按照临床医生的处方接受每日标准治疗。患者连续14天每天记录疼痛程度、药物使用情况和不良事件。14天后,SOC组患者可选择交叉接受PEMF治疗并持续16天。该研究由一个独立的临床研究组织监督。假设PEMF在疼痛管理方面优于SOC。 结果:与SOC相比,PEMF治疗具有显著的镇痛效果。收集了91例患者的完整数据,其中PEMF组48例,SOC组43例。PEMF组自基线起的最小二乘平均疼痛评分变化为-1.8(降低36%),显著超过SOC组的-0.46(降低10%)(p<0.0001)。PEMF组的药物使用从40%降至18%(降低55%),而SOC组从40%降至35%(降低12%)。在交叉亚组中,患者从SOC转换为PEMF治疗后,疼痛评分额外降低了18%,药物使用降低了63%。 结论:在管理疼痛和减少药物使用方面,PEMF明显比SOC更有效。对于关节和软组织疼痛的非侵入性、非药物管理,应考虑PEMF疗法。 试验注册:ClinicalTrials.gov标识符NCT05244187。
