The aim of this study is to evaluate the clinical efficacy of reduction of local fat on ipsilateral thigh through cryolipolysis (zeltiq) and controlateral thigh using by amplitude modulated frequency (conventional) method.

Condition Intervention Phase
Device: zeltiq
Device: electrical stimulation
Phase 1
Phase 2

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Factorial Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Clinical Efficacy of Local Fat Reduction on the Thigh of Korean Women Through Cryolipolysis

Further study details as provided by Wonik Trade Company, Korea:

Primary Outcome Measures:
  • clinical efficacy of fat reduction on thigh by femoral CT [ Time Frame: 1 month ]
    As the difference of fat amounts on both thigh measured by femoral CT will be evaluated, fat amounts, metabolic variables, gross appearance on ipsilateral thigh by cryolipolysis (Zeltiq) would be compared to those on controlateral thigh by frequency method for 4 weeks.

Secondary Outcome Measures:
  • clinical efficacy/safety of fat reduction through cryolipolysis [ Time Frame: 3 months ]
    Histological examination under skin biopsy, and gross appearance, and metabolic variables, and fat amounts by femoral CT, and questionnaire for satisfaction will be compared for past 3 months

Estimated Enrollment: 15
Study Start Date: July 2010
Estimated Study Completion Date: October 2010
Estimated Primary Completion Date: August 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: zeltiq
Cryolipolysis had been done for 1 hour on ipsilateral thigh fat through Zeltiq machine.
Device: zeltiq
Cryolipolysis had been conducted for targeted fat area on thigh for 1 hour through Zeltiq machine made in Zeltiq Aesthetics.
Other Name: zeltiq, cryolipolysis
Sham Comparator: electrical stimulation
Lipolysis had been done for 30 minutes on controlateral thigh fat through amplitude modulated frequency.
Device: electrical stimulation
Lipolysis would be done on controlateral thigh for 30 minutes through 3000 Hz- amplitude modulated frequency.
Other Name: electrical frequency

Detailed Description:

Cryolipolysis is a new concept to reduce fat since Zeltiq machine had been introduced several years ago. Several different trials such as high frequency, liposuction and chemical lipolysis to remove fat had been emerged and tried. Therefore, we would like to know the clinical efficacy of cryolipolysis through comparative experiment with former frequency method on each thigh on healthy Korean women.

Healthy premenopausal women who want to reduce the fat on thigh were included. 28 healthy volunteered women recruited for this study, 15 subjects among participated after interviewing, sampling their metabolic variables at initial visit. A total of 15 subjects would be investigated through food diary(24hour), femoral CT, anthropometric, metabolic variables at initial, 4th, 12th week. Histological examination under skin(initial and 12th week), questionnaire(4th, 12th week) for satisfaction, adverse events would be monitored during 3 month.
