Efficacy and Safety of Simultaneous Application of HIFEM and Synchronized Radiofrequency for Abdominal Fat Reduction and Muscle Toning: A Multicenter Magnetic Resonance Imaging Evaluation Study

BACKGROUND Radiofrequency and high-Intensity Focused Electromagnetic (HIFEM) field procedure are well-known, stand-alone, body-shaping modalities, yet their simultaneous application has not been investigated. OBJECTIVE The aim is to evaluate the efficacy of a novel device simultaneously delivering HIFEM and radiofrequency for subcutaneous fat reduction and muscle toning. MATERIALS AND METHODS Forty-one subjects with an average age of 39.7 ± 11.5 years were recruited. The subjects received 3 abdominal treatments (one per week). Magnetic resonance imaging images of the treated area were evaluated at baseline and at 1-, 3-, and 6-month visits for changes in subcutaneous fat, muscle thickness, and abdominal separation (AS). Anthropometric data and digital photographs were collected. Subject satisfaction and therapy comfort were evaluated. RESULTS The muscle mass increase peaked at 3 months, showing 26.1% thickening. The fat thickness reduction was most prominent at 3 months, showing a 30.8% reduction. The AS decreased by 18.8% at 3 months after treatment. The waist circumference reduced by 5.87 ± 3.64 cm at a 3-month follow-up. Six-month data showed maintenance of these outcomes. The treatment was considered as comfortable with high patient satisfaction. CONCLUSION The analysis of magnetic resonance imaging images and waist measurements showed that the therapy combining HIFEM and radiofrequency is highly effective in reducing subcutaneous fat and muscle thickening.
