Ultrasonographic Measurement After Multilayer Stimulation for Body Fat Reduction and Muscle Strengthening: A Pilot Study.

[BACKGROUND] Demand for noninvasive body contouring is rising as patients seek alternatives to liposuction. We evaluated a device combining electrical muscle stimulation, radiofrequency, and vacuum technology for abdominal fat reduction and muscle enhancement.

[METHODS] In a prospective study, 20 adults (15 women, 5 men; 28-50 y; body mass index [BMI] 22-28 kg/m²) received 16 sessions over 8 weeks (two 30-min sessions/wk) targeting the abdomen. Outcomes at baseline and 1 month posttreatment included ultrasonographic abdominal fat and muscle thickness, waist circumference, BMI, standardized photography, and patient-reported satisfaction. Safety and downtime were documented.

[RESULTS] At 1 month, mean abdominal fat thickness decreased by 0.61 cm (95% confidence interval [CI], 0.48-0.74; < 0.001), and muscle thickness increased by 0.24 cm (95% CI, 0.17-0.31; < 0.001). Waist circumference reduced by 2.13 cm (95% CI, 1.81-2.45; < 0.001), and BMI changed by -0.53 (95% CI, -0.59 to -0.54; < 0.001). Standardized images and patient ratings indicated improved contour and skin elasticity. The treatments were well tolerated, with high satisfaction and minimal downtime.

[CONCLUSIONS] Combined electrical muscle stimulation, radiofrequency, and vacuum therapy produced significant reductions in abdominal fat and waist size, increased muscle thickness, and improved perceived contour with favorable tolerability. These findings support this multimodal, noninvasive approach as a promising option for abdominal shaping.
