Several studies on the simultaneous use of high-intensity focused electromagnetic field (HIFEM) and radiofrequency (RF) have shown safety and effectiveness of fat reduction and muscle mass increases in other parts of the body. This study investigated HIFEM+RF procedure effect on muscle mass and adipose tissue in the upper arms.
Thirty-four subjects enrolled in this multicentric study underwent four, 30-minute bilateral procedures over the upper arms spaced one week apart, with the device simultaneously emitting HIFEM and RF energies. Fat and m. triceps muscle tissue change was measured via magnetic resonance imaging at baseline, 1-month, and 3-month follow-up visits. Additionally, digital photographs, patient comfort, and satisfaction questionnaires were obtained. The trial is registered on ClinicalTrials.gov under NCT04596241.
MRI images analysis showed significant improvement at both follow-up visits. At 1-month follow-up (n=28) patients showed 22.3 percent (-4.0±1.2 mm) decrease of average fat tissue, and 21.5 percent (+8.2±2.3 mm) muscle mass increase. Twenty-five patients completed the 3-month follow-up visit, with average decrease in fat tissue by 25.5 percent (-4.9±1.5 mm) and average increase in muscle mass by 23.9 percent (+8.9±2.01 mm). Analysis of questionnaires revealed high satisfaction with the results (84.64%), high comfort during the treatment (91.18%), and low VAS score (1.58±2.0), indicating painless procedure.
Presented results demonstrate the safety and effectiveness of the HIFEM+RF procedure for muscle mass increase and fat reduction in the upper arm area. These findings correspond with the outcomes seen in other body parts.
多项关于同时使用高强度聚焦电磁场（HIFEM）和射频（RF）的研究表明，其在减少身体其他部位脂肪和增加肌肉量方面具有安全性和有效性。本研究调查了HIFEM+RF程序对上臂肌肉量和脂肪组织的影响。
34名受试者参与了这项多中心研究，在上臂接受了4次、每次30分钟的双侧治疗，每次治疗间隔一周，治疗设备同时发射HIFEM和RF能量。在基线、1个月和3个月随访时，通过磁共振成像测量脂肪和肱三头肌肌肉组织的变化。此外，还获取了数码照片、患者舒适度和满意度问卷。该试验已在ClinicalTrials.gov上注册，注册号为NCT04596241。
MRI图像分析显示，两次随访时均有显著改善。在1个月随访时（n=28），患者平均脂肪组织减少22.3%（-4.0±1.2毫米），肌肉量增加21.5%（+8.2±2.3毫米）。25名患者完成了3个月随访，脂肪组织平均减少25.5%（-4.9±1.5毫米），肌肉量平均增加23.9%（+8.9±2.01毫米）。问卷分析显示，患者对结果的满意度较高（84.64%），治疗期间舒适度较高（91.18%），视觉模拟评分较低（1.58±2.0），表明该治疗过程无痛。
目前的研究结果表明，HIFEM+RF程序在上臂区域增加肌肉量和减少脂肪方面具有安全性和有效性。这些发现与在身体其他部位观察到的结果一致。
