Study Type Interventional
Study Design Allocation: Non-Randomized;   Intervention Model: Single Group Assignment;   Masking: Double (Investigator, Outcomes Assessor);   Primary Purpose: Treatment
Condition Adipose Tissue
Interventions Device: multipolar RF, varipulse
Device: cryolipolysis
Enrollment 10
Recruitment Details Ten subjects between the ages of 21 and 50 years of age, requesting a reduction in focal fat of the flanks were recruited from a single outpatient clinic.
Pre-assignment Details Subjects received one session of cryolipolysis treatment on both sides of their body before one side of their body was treated with multipolar radiofrequency plus varipulse technology. Each subject acted as their own control.
Arm/Group Title Cyrolipolysis Cryolipolysis, Multipolar RF With Varipulse Technology
Hide Arm/Group Description Each side of the subject received a cryolipolysis treatment. One side of the body received cryolipolysis plus multipolar radiofrequency with varipulse technology

Each subject received a single cryolipolysis treatment on both sides of their body.
[2]
Each subject received multipolar RF with varipulse technology to only one side of their body.
Arm/Group Title Cryolipolysis Treatment & Cryolipolysis With Legacy
Hide Arm/Group Description Each patient is their own control. Both flanks will be treated with cryolypolysis. The flank will be divided into two equal treatment areas where one side will receive multipolar radiofrequency with varipulse technology treatment and the other side will not.

Hide Baseline Analysis Population Description
Each subject received a cryolipolysis treatment to both sides of body. One side of the flank will then receive multipolar RF and PEMF with Varipulse technology and the other side will not.

1.Primary Outcome
Title General Improvement in Skin Laxity of the Flank Area
Hide Description Independent reviewer to identify the six month post-treatment photograph of the flank area treated with multi-polar radiofrequency, pulsed electro-magnetic fields and vacuum suction using the Global Aesthetic Improvement Scale (GAIS) where 3 = very much improved, 2 = much improved, 1 = improved, 0 = no change, -1 = worse, -2 = Much worse and -3 = very much worse.
Time Frame 6 months

Hide Statistical Analysis 1
Statistical Analysis Overview Comparison Group Selection Cryolipolysis Treatment & Cryolipolysis With Legacy
Comments The null hypothesis was that the addition of the multipolar radiofrequency with varipulse technology treatment to the cryolipolysis treatment would not show visual improvement.
Type of Statistical Test Superiority
Comments A significant improvement in skin laxity reduction is defined as a mean average increase in grade of 1 as per the GAIS.
Statistical Test of Hypothesis P-Value <0.01
Comments [Not Specified]
Method Wilcoxon (Mann-Whitney)
Comments Used Wilcoxon Matched-Pairs Signed-Ranks test
Time Frame Adverse events were collected for 11 months and 1 day.
