BackgroundEnergy-based treatments include ultrasound, lasers, cryolipolysis, and radiofrequency. The most recent energy treatment for noninvasive body contouring is electromagnetic treatments—a hot topic in plastic surgery today. A systematic review to assess efficacy and safety has not been published.MethodsAn electronic search was performed using PubMed to identify the literature describing electromagnetic treatments. Measurements from imaging studies were tabulated and compared.ResultsFourteen clinical studies were evaluated. Two studies included simultaneous radiofrequency treatments. In 11 studies, the Emsculpt device was used; in 2 studies, the Emsculpt-Neo device was used. One study included a sham group of patients. The usual protocol was 4 treatments given over a 2-week period. No complications were reported. Eight studies included abdominal measurement data obtained using magnetic resonance imaging, computed tomography, or ultrasound. Photographic results were typically modest. Photographs showing more dramatic results also showed unexplained reductions in untreated areas.Measurement variances were high. The mean reduction in fat thickness was 5.5 mm. The mean increment in muscle thickness was 2.2 mm. The mean decrease in muscle separation was 2.9 mm (P = 0.19). Early posttreatment ultrasound images in 1 study showed an echolucent muscle layer, compared with a more echodense layer at the baseline, consistent with tissue swelling after exercise. Almost all studies were authored by medical advisors for the device manufacturer.DiscussionMeasurement data show small reductions in fat thickness, occurring almost immediately after the treatments. Adipocyte removal without tissue swelling would be unique among energy-based treatments. Similarly, muscle hypertrophy is not known to occur acutely after exercise; muscle swelling likely accounts for an early increment in muscle thickness. Any improvement in the diastasis recti is likely fictitious.ConclusionsElectromagnetic treatments, either administered alone or in combination with radiofrequency, are safe. However, the evidence for efficacy is tenuous. Measured treatment effects are very small (<5 mm). Conflict of interest and publication bias are major factors in studies evaluating energy-based alternatives. The evidence-based physician may not be satisfied that an equivocal treatment benefit justifies the time and expense for patients.

“…The study subject device, with its handpieces, shown in Figure 5, adapts perfectly to the different areas of the body treated and transmits electromagnetic energy directly to the muscle tissue, contracting and releasing it. This type of stimulation is superior to that achievable voluntarily by the user and it is already successfully used for body remodeling with excellent results [17,31].…”

Background and Objective: In recent years, a strong desire for slimmer and healthier-looking bodies has grown in the population. The aim of this study was to evaluate the effectiveness and safeness of the new technology Flat Magnetic Stimulation for buttock and abdomen remodeling in athletic subjects. Methods: A total of 49 patients (31 females and 18 males) were enrolled. Patients’ digital photos and buttocks/abdomen circumference measurements were taken to assess and monitor the effectiveness of treatment on muscle firming. The level of patient satisfaction was evaluated by a questionnaire based on a seven point Likert scale. Average scores were calculated at a 1-month follow-up (FU). Results: A significant increase in the buttocks’ mean circumference from 85.5 ± 0.7 cm to 88.5 ± 0.7 cm (p < 0.05) and in the abdomens’ mean circumference from 76.5 ± 9.19 cm to 78 ± 9.89 cm (p < 0.05) was observed 1 month after the last treatment. All subjects reported that their buttocks and abdomens felt more lift and toned. The average abdomen and buttocks satisfaction scores improve significantly at 1-month FU. Conclusions: Our data show that FMS treatment could be used as an effective mechanism for muscle toning.

“…2 Notably, these body contouring techniques do not address underlying musculature, despite musculature representing a vital aspect of the sculpted physique. 3,4 Aesthetic muscle stimulation (AMS) by using high-intensity focused electromagnetic field (HIFEM) or direct electrical muscle stimulation (EMS) is becoming a popular treatment that can target both the musculature and adipose tissue for superior aesthetic outcomes. 5 The objective of this study was to provide a comprehensive review of magnet-based AMS techniques and critically evaluate the current literature on its use in noninvasive body contouring.…”

Muscle Stimulation for Aesthetic Body Shaping: A Comprehensive and Critical Review

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.
