Non-thermal pulsed ultrasound treatment for the reduction in abdominal fat: A pilot study

10 female subjects with body mass index of 24 (range 22-29) underwent 3 biweekly UltraShape treatments for abdominal fat. Ultrasound imaging of the targeted fat layer and skin caliper measurements decreased significantly following treatment.

Study Details:

  • 10 female subjects with mean age 52 years (range 39-60), Fitzpatrick Skin Types I-IV and body mass index 24 (range 22-29)
  • 3 biweekly UltraShape treatments with U-Sculpt or VDF transducer in single-pass mode to abdomen with mean focal treatment zones (FTZ) of 8.3 (range 6 to 10)
  • Skin caliper and ultrasound measurements post-treatment compared to baseline

Study Results:

  • Little or no discomfort, mean pain level of 0.3 (Tx 1), 0.4 (Tx 2) and score of 0 for all subjects with Tx 3 (scale of 0=no pain to 10)
  • Ultrasound imaging of the targeted fat layer decreased significantly by 13%, 16%, and 13% at follow-ups, respectively
  • Fat layer as performed by skin calipers decreased by 12%, 10%, and 13% at follow-ups, respectively
  • All subjects noted improvement at the final follow-up
  • No immediate skin response following treatment
  • No adverse events
