Safety and efficacy of a novel high-intensity focused electromagnetic technology device for noninvasive abdominal body shaping.

Abstract

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 23.8kgm-2 ) underwent 4 treatments on abdomen with high-intensity focused electromagnetic (HIFEM) field device. Treatments took 30minutes and were spaced apart by 2-3days. 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±2.63cm (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.
