Body shaping with acoustic wave therapy AWT(®)/EPAT(®): randomized, controlled study on 14 subjects

J Cosmet Laser Ther. 2011 Dec;13(6):291-6. doi: 10.3109/14764172.2011.630089.


Introduction: Reduction of localised adiposities by non invasive means is a very frequent request among the female and male population.

Objective: The objective of this study is to demonstrate the efficacy and safety of AWT(®), combining two different mechanical waves, planar AWT and radial AWT during the same session, in volume reduction of saddle bags in women.

Methods: Treatment was performed on the saddle bag areas of 14 female patients, with the CELLACTOR(®) SC1 (Storz Medical AG, Tägerwilen, Switzerland) using extracorporeal pulse activation technology, EPAT(®). This device includes two handpieces, the C-ACTOR(®) and the D-ACTOR(®). Within 4 weeks, eight AWT(®) treatment sessions have been performed with both applicators. Follow-up visits were performed 1, 4 and 12 weeks after the last treatment.

Results: Measurements with the ultrasound system clearly demonstrate a significant diminution in the subcutaneous fat layer thickness and a reduction of the averaged circumference of thighs.

Conclusions: This study, although performed on a small number of patients, tends to show the safety and efficacy of AWT(®) in treating localized fat areas in a non-invasive way. There is also an additional benefit for patients in reducing the cellulite appearance and improving the skin firmness at the same time by using AWT(®).
