Descriptive Information

• Brief Title: Efficacy and Safety Study of Electroacupuncture for Simple Female Stress Urinary incontinence-a Multicenter Trial
• Official Title: The Efficacy and Safety Study of Electro-acupuncture for Simple Female Stress Urinary Incontinence- a Multicenter, Randomized Controlled Trial
• Brief Summary: The purpose of this study is to evaluate the efficacy and safety of electroacupuncture （EA） for simple female stress urinary incontinence.
• Detailed Description: Stress urinary incontinence (SUI) is a common disease of female. The inconvenience caused by SUI affects the patients' quality of life and health seriously. To date, there has not specific therapy on SUI. Former research showed acupuncture may work for SUI. This multi-center randomized controlled clinical trial of acupuncture for simple female stress urinary incontinence is designed to confirm the efficacy and safety of EA. This project is conducted by Chinese researchers, supported by the Chinese Government. The research result is expected to provide high quality evidence of EA for simple female stress urinary incontinence.
• Study Type: Interventional
• Study Phase: Phase 2
• Study Design: Allocation: Randomized; Intervention Model: Parallel Assignment; Masking: Double (Participant, Outcomes Assessor); Primary Purpose: Prevention
• Condition: Urinary Stress Incontinence

Intervention

• Device: electroacupuncture group
  Procedure: electro-acupuncture;Points: Bilateral Zhongliao (BL33) Huiyang(BL35).Specially-made pad is stick on pierced acupoints. Bilateral BL33 are given acupuncture of 50～60mm with 30～45°angle to inward and downward by 75mm filiform needle. Bilateral BL35 are given acupuncture of 50～60mm to outward and upward by 75mm filiform needle. Twirl, lift and thrust for 3 times, until local sour and heavy feeling coming.The electric stimulator is applied to bilateral BL33 and BL35, with continuous wave,50 Hz and electric current 1- 5mA.Every session lasts for 30 min per day.The participants are treated continuously for 6 weeks for 3 sessions a week, 18 sessions for each patient in all. The treatment is designed based on recent literature research in 10 years, former result and expert consensus.
  Other Name: SDA-V electroacupuncture apparatus(Huatuo,made in China)
• Device: sham electroacupuncture group
  Procedure: sham electroacupuncture;Points: Bilateral sham Zhongliao (BL33) sham Huiyang(BL35).Specially-made pad is stick on pierced acupoints. Both sham BL33 and BL35 are given non-penetrating needling with blunt needle. Twirl, lift and thrust for 3 times. The sham electric stimulator is applied to bilateral sham BL33 and sham BL35. The mental wire has been cut off with a same outlook as the treatment group. The electric stimulator is looked normal but with no current output. Length of Treatment and the treatment sessions are the same as treatment group.
