The high-intensity focused electromagnetic field (HIFEM) procedure is an effective method for noninvasive toning and shaping of buttocks.
To investigate and compare the efficacy of simultaneous application of HIFEM procedure with radiofrequency (RF) heating vs HIFEM standalone procedure on the buttocks.
Sixty-seven subjects (21-67 years, BMI 16-34 kg/m) were recruited and divided into two groups. Group A received simultaneous HIFEM + RF therapy, and group B received standalone HIFEM treatments. All participants underwent four 30-minute bilateral treatments on the buttocks. The MRI was used to evaluate the changes in muscle and fat thickness.
Data of 32 subjects from group A and 31 subjects from group B were reviewed at 1-month follow-up. On average, subjects from group A showed a 31.3% higher increase in muscle thickness, as shown in the MRI evaluation. The gluteal muscle thickness continued to grow and peaked at a 3-month follow-up, wherein 27 patients were evaluated in each group ( = 54). Group A showed on average +24.7% increase (gluteus maximus +8.5 ± 1.9 mm, medius +6.0 ± 1.1 mm, minimus +2.9 ± 0.8 mm), while group B exhibited only +15.9% increase in muscle thickness (gluteus maximus +5.2 ± 1.1 mm, medius +3.6 ± 1.0 mm, minimus +1.6 ± 0.4 mm). On average, group A showed a 35.6% higher growth in muscle thickness. Treatments were safe and comfortable with high satisfaction rates. No adverse event was reported throughout the study.
Our results suggest that simultaneous use of HIFEM + RF is safe and significantly more effective for gluteal contouring than the HIFEM procedure alone.
高强度聚焦电磁场（HIFEM）疗法是一种用于臀部非侵入性塑形的有效方法。
研究并比较HIFEM疗法联合射频（RF）加热与单纯HIFEM疗法对臀部的疗效。
招募了67名受试者（年龄21 - 67岁，体重指数16 - 34 kg/m），并将其分为两组。A组接受HIFEM + RF联合治疗，B组接受单纯HIFEM治疗。所有参与者均在臀部接受了4次每次30分钟的双侧治疗。采用磁共振成像（MRI）评估肌肉和脂肪厚度的变化。
在1个月的随访中，对A组的32名受试者和B组的31名受试者的数据进行了回顾。MRI评估显示，A组受试者的肌肉厚度平均增加了31.3%。臀肌厚度持续增长，并在3个月的随访中达到峰值，此时每组评估了27名患者（n = 54）。A组平均增加了24.7%（臀大肌增加8.5 ± 1.9 mm，臀中肌增加6.0 ± 1.1 mm，臀小肌增加2.9 ± 0.8 mm），而B组的肌肉厚度仅增加了15.9%（臀大肌增加5.2 ± 1.1 mm，臀中肌增加3.6 ± 1.0 mm，臀小肌增加1.6 ± 0.4 mm）。A组的肌肉厚度平均增长高出35.6%。治疗安全舒适，满意度高。在整个研究过程中未报告不良事件。
我们的结果表明，与单纯的HIFEM疗法相比，同时使用HIFEM + RF对臀部塑形安全且显著更有效。
