Low-Frequency, High-Intensity Ultrasound for Waist Circumference Reduction

Not Applicable

Completed

Brief Summary: This study evaluates the effectiveness and safety of externally applied lower frequency ultrasound to the waist/abdominal region of adults to achieve a reduction of fat cells/tissues below the skin, evidenced by a reduction in patient waist circumference.

Detailed Description: This study is to evaluate principally the effectiveness, and secondarily the safety, of external application of lower frequency ultrasound to the waist/abdominal region of adults to achieve a reduction of adipose cells/tissues in the subcutaneous region. The application of higher frequency (200kHz to 3MHz) ultrasound for this purpose has previously been demonstrated and such devices have received clearance for treatment in the United States. The question remains whether application of ultrasound at a lower frequency (35kHz to 45kHz) can achieve comparable results without introducing any new or elevated risks to the patient. This study will apply 3 treatments of the ultrasound energy and evaluate the change in patient's waist circumference, which would be evidence of reducing sub-cutaneous adipose cells/tissues.

Arm && Interventions

Group	Intervention	Description
Treatment group	Ultrasound	Each patient shall receive a total of 3 treatments. Each treatment shall consist of applying the ultrasound device for 30 minutes to the skin surface, working the device methodically over the abdominal area. The device shall be set at the maximum emission level, have an intensity of approximately 1.0 watt/cm\^2.

Primary Outcome Measures

Name	Time	Method
Waist Circumference Change	The difference between the circumference measurement immediately prior to the first treatment (Baseline) to immediately after the 4-week follow-up assessment (approximately 6 weeks from Baseline).	Change in measurable circumference of the patient's abdominal area from Baseline to immediately after the 4-week follow-up assessment (approximately 6 weeks from Baseline).

Secondary Outcome Measures

Name	Time	Method
Number of Participants With Pain	Assessed during and immediately after (up to 15 minutes after use ceased) each application of the device, and at 1 week, 4 weeks, and 12 weeks post-treatment.	Incidence of pain during each application of the device and/or immediately following each application of the device (up to 15 minutes after use of the device ceased).
