Brief Summary:
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 or disease Intervention/treatment Phase
Lipolysis Cryotherapy Effect Device: zeltiq Device: electrical stimulation Not Applicable

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.

Primary Outcome Measures :
  1. Change in Cross Sectional Area of Fat in Both Thighs [ Time Frame: 4 weeks ]
    reduction of fat amounts on both thighs measured by computerizing tomography

  2. Change of the Girths in Both Thighs [ Time Frame: 4 weeks ]
    Mean differences of the circumferences of both thighs measured by inches

Secondary Outcome Measures :
  1. Change of the Fat Amount of Both Thighs Between Baseline and 12 Weeks [ Time Frame: baseline and 12 weeks ]
    The mean differences of the Cross-Sectional Areas of both Thighs between Baseline and 12 weeks

  2. Change of Girths in Both Thighs for 12 Weeks [ Time Frame: 12 weeks ]
    Comparison of circumferences of both thighs for 12 weeks

  3. Weight Change for 12 Weeks [ Time Frame: baseline and 12 weeks ]
    Change in weight for 12 weeks
