Brief Summary:
The purpose of this study is to determine whether electroacupuncture is effective on waist circumference in obesity.

Condition or disease Intervention/treatment Phase
Obesity Device: Electroacupuncture Device: Sham electroacupuncture procedure Phase 2

Detailed Description:
Many studies have reported on the beneficial effects of acupuncture for obesity, although some negative reports also existed.(Wang F. et al. 2008)Recently conducted systematic review of Pittler and Ernst reported that there was insufficient, but not conclusive evidence to support the efficacy of acupuncture and acupressure for weight loss. However, most of these studies had methodological limitation, such as lack of adequate control group or unclear specific effect of electroacupuncture alone because auricular acupuncture was administered as well. In this sudy, we had three-arm randomized controlled trial(with sham control group) to investigate whether electroacupuncture is effective in the treatment of obesity.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 39 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single (Participant)
Primary Purpose: Treatment
Official Title: The Effect of Low Frequency Electroacupuncture on Waist Circumference in Obesity-Three Arm Randomized Controlled Trial, Pilot Study
Study Start Date : January 2010
Estimated Primary Completion Date : May 2010
Estimated Study Completion Date : May 2010

Arm Intervention/treatment
Experimental: Electroacupuncture
The Electroacupuncture therapy protocol included a total of 12 acupuncture points at the CV12,CV6, bilateral ST25, SP15, SP14,LI4, LI11, ST36, ST44. All acupuncture points were prepared with 70% alcohol pads, and disposable stainless steel needles were used. Abdominal acupuncture points were inserted horizontally 6~6.5cm in depth and the others were inserted vertically 2~2.5cm in depth until patient can feel De-Qi. All acupuncture points were stimulated electrically with a frequency of 24 Hz an intensity of 0.27-1.3mA(tolerable strength) with continuous stimulation by the pulse generator. The participants were given treatment twice a week for 30 minutes for 5 weeks by practitioner who had had 6 years of acupuncture training and 3 more years of clinical experience.
Device: Electroacupuncture
We used Electrical stimulator(STN-111,Stratek)with a frequency of 24 Hz and intensity of 0.27-1.3mA(tolerable strength), asymmetric interactive pulse with continuous stimulation by the pulse generator. The participants were given treatment twice a week for 30 minutes for 5 weeks(10 sessions) by practitioner.(n=13)
Other Name: EA group
Sham Comparator: Sham electroacupuncture procedure
The Sham electroacupuncture therapy protocol(Non-acupoint, No electrical stimulation)included the same number and type of needle, duration, frequency of sessions and practitioner as for the EA treatment, but superficially at non acupuncture points 15 mm to the lateral of each acupuncture point was treated. The points were not stimulated electrically, but the sound of the pulse generator was heard by the participants. (Lee SH, LeeBC 2009) Those receiving EA or SEA therapy were treated on alternate days to prevent crosstalk among groups, which could have compromised the blinded study design.
Device: Sham electroacupuncture procedure
We used same electroacupuncture device, number and type of needle, duration, frequency of sessions and practitioner as for the EA treatment. Specific details are as described in the arm description.(n=13)
Other Name: Sham EA group
No Intervention: Waiting list
No treatment was done for waiting group, but could receive same treatments as Electroacupuncture group after the end of trial.
