The Effects of Combined Noninvasive Radiofrequency and Ultrasound Cavitation on Anthropometric Indices: A Four-Group Interventional Study

Subcutaneous fat reduction is performed using different noninvasive body contouring techniques including noninvasive radiofrequency (RF) and ultrasound cavitation (USC). The aim of this study was to evaluate the effects of combined RF-USC on anthropometric indices among obese and overweight people. This four-group interventional study was conducted on 149 obese and overweight individuals. Participants were allocated to an abdomen and flank group (n = 82), an abdomen and hip group (n = 34), an abdomen and thigh group (n = 13), and a control group (n = 20). Participants in the three intervention groups received combined RF-USC twice a week for five consecutive weeks and followed a low-calorie diet. Except for hip circumference, other anthropometric indices (including abdomen, waist, and thigh circumferences) significantly decreased after ten-session combined RF-USC. However, no statistically significant differences were detected among the groups concerning pretest and posttest mean values of body fat mass and body weight. Ten-session combined RF-USC is effective in significantly reducing abdomen, waist, and thigh circumferences among obese and overweight individuals.
