Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

After being informed about the study and potential risk, all patients giving written informed consent form will be undergo a 1-week screening period to determine eligibility for study entry. Eligible patients will be randomly assigned to one of the two groups 1) electroacupuncture group: electroacupuncture will be provided to patients at BL33, BL35 and SP6 for 3 time per week for the first 4 weeks, then twice a week for 4 weeks, and once a week for the last 4 weeks. There will be 24 times of treatment in total in 3 month; 2) sham electroacupuncture group: sham electroacupuncture will be provided to patients at sham acupoints to BL33, BL35 and SP6 with the same schedule as electroacupuncture group.The follow-up time for the two groups are 6 months after treatment. Primary and secondary outcome will be measured at 3, 6, and 9 months from the start of the treatment, respectively.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: electroacupuncture group
patients will receive electroacupuncture at 3 acupoints(Bladder meridian of foot-taiyang 33 and 35#BL33 and BL35), and Spleen meridian of foot-taiyin 33(SP6)) 3 times/week for 4 weeks, then 3 times/week for 4 weeks, and then once/week for 4 weeks(24 times in total in 3 months), and be followed up for 6 months after treatment. Disposable acupuncture needles with size of 0.30 × 75 mm will be used at BL 33 and BL 35, and needles with size of 0.30 ×40 mm at SP 6. Standardized electroacupuncture apparatuses will be used, and the stimulation will last for 30 minutes with a continuous wave of 20 Hz, and a current intensity of 2 to 6.5 mA at BL33 and BL 35, and 1 to 3.5 mA at SP6.
Other: electroacupuncture
the same as described in experimental arm.
Sham Comparator: sham electroacupuncture group
patient will receive sham electroacupuncture with the same frequency and amount as applied in the electroacupuncture group, as well as the follow-up period. Disposable acupuncture needles with size of 0.30 × 40 mm will be applied and penetrate the skin of patients for 2 to 3mm at sham acupoints to the 3 acupoints mentioned above. The stimulation will only last for 30-second with a very weak currency intensity and a continuous wave of 20 Hz.
Other: sham electroacupuncture
the same as described in sham comparator.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
the change from baseline on the score of the Pelvic Floor Distress Inventory-short form 20 (PFDI-20)
Time Frame: at baseline, and 3 months when the treatment is completed.
Data will be collected via the the Pelvic Floor Distress Inventory-short form 20 (PFDI-20) . The questionnaire consists of three sections, pelvic organ prolapse distress inventory 6 (POPDI-6), colorectal-anal distress inventory 8 (CRADI-8), and urinary distress inventory 6 (UDI-6). Each section has 6-8 questions with 5 answers rated from 0-4 in each, and mean score of each section is the total score of this section divided by number of questions in this session. Then the sum of the mean scores of the three section timing 25 will come to the total score of the questionnaire(0-300). The higher the total score is, the severer the symptoms are.
at baseline, and 3 months when the treatment is completed.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.

Time Frame: 6 months and 9 months since the start of the treatment.
Data will be collected via the Pelvic Floor Distress Inventory-short form 20 (PFDI-20) . The questionnaire consists of three sections, pelvic organ prolapse distress inventory 6 (POPDI-6), colorectal-anal distress inventory 8 (CRADI-8), and urinary distress inventory 6 (UDI-6). Each section has 6-8 questions with 5 answers rated from 0-4 in each, and mean score of each section is the total score of this section divided by number of questions in this session.

6 months and 9 months since the start of the treatment.
number of patients at different levels of pelvic organ prolapse quantitative examination(POP-Q)
Time Frame: at baseline, and 3 months when the treatment is completed.
Pelvic organ prolapse quantitative examination(POP-Q) is a manual approach to measure the severity of female pelvic organ prolapse with five level from 0 to 4 . The POP-Q examination will be conducted by experienced gynecologists in each participating center. The higher the level is, the severer the symptoms are.
at baseline, and 3 months when the treatment is completed.

Time Frame: at baseline, 3 months, 6 months and 9 months since the start of the treatment.
Data will be collected via the Pelvic Floor Impact Questionnaire Short Form-7（PFIQ-7) , which uses 7 questions to evaluate the impact of bladder, colorectal and virginal symptoms on daily life, respectively. For each type of symptoms, the answer to one question has four levels, no bother(0), mild bother(1), moderate bother(2), severe bother(3). The higher the total score is, the severer the quality of life is impacted.
at baseline, 3 months, 6 months and 9 months since the start of the treatment.

Time Frame: at baseline, 3 months, 6 months and 9 months since the start of the treatment.
Data will be collected via International Consultation on Incontinence Questionnaire-Short Form(ICIQ-SF) questionnaire. The total score(0-21scores) is an accumulated scores from question 1 to 3. The higher the total score is, the severer the incontinence is.
at baseline, 3 months, 6 months and 9 months since the start of the treatment.
the change from baseline on the score of pelvic organ prolapse/urinary incontinence sexual questionnaire-12(PISQ-12)
Time Frame: at baseline, 3 months, 6 months and 9 months since the start of the treatment.
Data will be collected via pelvic organ prolapse/urinary incontinence sexual questionnaire-12(PISQ-12), which uses 10 questions to evaluate the impact of pelvic organ prolapse/urinary incontinence on sexual life for patients. The answer to each question has five levels, including always(4), often(3), sometimes(2), rarely(1), never(0). The higher the total score is, the severer the impact of pelvic organ prolapse/incontinence to sexual life is.
