Abstract

Abstract : Supplemental Digital Content is Available in the Text. Abstract : BACKGROUND: Aesthetic muscle stimulation (AMS) using high-intensity electromagnetic field (HIFEM) targets skeletal muscle neurons, causing muscle hypertrophy and loss of adipose tissue, thereby cultivating a sculpted physique. Many studies have evaluated AMS for noninvasive body contouring; however, the efficacy, safety, and long-term data remain unclear. OBJECTIVE: To critically evaluate the current literature on the use of electromagnetic muscle stimulation for body contouring and provide a consensus on patient selection and long-term efficacy of AMS. MATERIALS AND METHODS: PubMed and Embase were searched using the terms: "HIFEM, " "Electromagnetic therapy, " and "muscle" or "Electrical stimulation muscle treatments" and "aesthetics." Studies involving the use of muscle stimulation for nonaesthetic/dermatologic, in vitro studies or studies involving animals were excluded. RESULTS: Twenty studies in total were included [9 moderate-quality, 8 low-quality, and 3 very low‒quality studies] based on the Grading of Recommendations, Assessment, Development, and Evaluation scale, representing 521 patients. Body sites evaluated included the abdomen (378 patients), buttock (156 patients), arms (22 patients), and calves (15 patients). CONCLUSION: Electromagnetic muscle stimulation represents an effective therapeutic intervention for abdominal contouring that yields increased muscle thickness, and reduced abdominal fat thickness, for up to 1 year after treatment. Larger, controlled studies are needed to determine the efficacy of electromagnetic muscle stimulation alone for contouring of buttocks, thighs, arms, and calves.
