Thermal fat reduction technologies are leading the market for nonsurgical abdominal contouring. However, they are ideal principally for patients with fat bulges.
Our study investigates the effects of a novel nonthermal technology affecting the abdominal musculature and subcutaneous adipose tissue.
A total of 22 patients (avg. BMI 23.8 kg m ) underwent 4 treatments on abdomen with high-intensity focused electromagnetic (HIFEM) field device. Treatments took 30 minutes and were spaced apart by 2-3 days. Photographs, weight, and waist measurements were taken at the baseline, after the last treatment, and at month 3 follow-up. Patient satisfaction was noted. Photographs were evaluated by blinded evaluators.
The study protocol was completed by 19 patients. At month 3, the average waist size reduction was 4.37 ± 2.63 cm (P < 0.01). The evaluators identified the before image from the 3-month image 89.47% of the time. About 91% of patients reported their abdominal appearance improved, and 92% stated they are satisfied with treatment results at month 3. No adverse events occurred.
Observed waist size reduction and aesthetic improvement appear to be a combination of fat reduction and increased muscle definition of abdominal wall. In lower BMI patients, the increased abdominal muscle definition was largely responsible for the improvement. This novel energy device provides an additional tool for body contouring with primary application for lower and medium BMI patients.
热脂肪减少技术引领着非手术腹部塑形市场。然而，它们主要适用于有脂肪凸起的患者。
我们的研究调查了一种影响腹部肌肉组织和皮下脂肪组织的新型非热技术的效果。
共有22名患者（平均BMI为23.8kg/m²）使用高强度聚焦电磁（HIFEM）场设备对腹部进行了4次治疗。每次治疗持续30分钟，间隔2 - 3天。在基线、最后一次治疗后以及3个月随访时拍摄照片、测量体重和腰围。记录患者满意度。照片由不知情的评估人员进行评估。
19名患者完成了研究方案。在3个月时，平均腰围减少了4.37±2.63厘米（P < 0.01）。评估人员在89.47%的情况下能从3个月时的图像中识别出之前的图像。约91%的患者报告其腹部外观有所改善，92%的患者表示对3个月时的治疗效果满意。未发生不良事件。
观察到的腰围减少和美学改善似乎是脂肪减少和腹壁肌肉清晰度增加的综合结果。在BMI较低的患者中，腹部肌肉清晰度的增加在很大程度上促成了这种改善。这种新型能量设备为身体塑形提供了一种额外的工具，主要适用于BMI较低和中等的患者。
