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 three groups 1) electroacupuncture group: electroacupuncture will be provided to patients at BL33, BL35 and SP6 for 3 time per week for 8 weeks; 2) sham electroacupuncture group: sham electroacupuncture will be provided to patients at sham acupoints to BL33, BL35 and SP6 for 3 time per week for 8 weeks.The follow-up time for the first two groups are 24 weeks and life style counselling will be provided once when receiving the first acupuncture treatment(contents are the same as the life style counselling group). 3) life style counselling group: life style advice will be provided to patients at enrolment with content on drinking, diet, weight control, lung disease, urinary track infection control, and etc. Patients in this group will be followed up for 20 weeks. Primary and secondary outcome will be measured at 4, 8, 20, 32 weeks, respectively.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: electroacupuncture 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 8 weeks(24 times in total), followed with 24-weeks follow up. 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. Standardised 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. Life style counselling will be provided to all patients and contents are as same as the life style counselling group. |
Other: electroacupuncture
same as described in experimental arm.
Behavioral: life style counselling
life style counselling to patients with mixed urinary incontinence contains advice on daily drinking, caffeine intake, diet, constipation, exercise, heavy lifting, lung disease, urinary track infection and etc.
|
| Sham Comparator: sham electroacupuncture 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. Life style counselling will be provided to all patients and contents are as same as the life style counselling group. |
Other: sham electroacupuncture
same as described in sham comparator.
Behavioral: life style counselling
life style counselling to patients with mixed urinary incontinence contains advice on daily drinking, caffeine intake, diet, constipation, exercise, heavy lifting, lung disease, urinary track infection and etc.
|
| Other: life style counselling group patients randomised to this group will receive a one-time life style counselling at the enrolment to improve their daily behaviour to expedite the recovery of their mixed urinary incontinence. Then the patients will be followed up for 20 weeks. |
Behavioral: life style counselling
life style counselling to patients with mixed urinary incontinence contains advice on daily drinking, caffeine intake, diet, constipation, exercise, heavy lifting, lung disease, urinary track infection and etc.

Outcome Measures
Primary Outcome Measures
- the proportion of participants with at least 50 percent decrease from baseline in the mean 24-hour incontinence episodes. [at the 8th week after the last treatment]
data will be collected and evaluated by 72-hour incontinence episodes dairy
Secondary Outcome Measures
- the proportion of participants with at least 50 percent decrease from baseline in the mean 24-hour incontinence episodes [at baseline, 4th, 20th and 32nd week]
data will be collected and evaluated by 72-hour incontinence episodes dairy
- the proportion of participants with at least 50 percent decrease from baseline in the mean 24-hour urgent incontinence episodes [at baseline, 4th, 8th 20th and 32nd week]
data will be collected and evaluated by 72-hour incontinence episodes dairy
- the proportion of participants with at least 50 percent decrease from baseline in the mean 24-hour stress incontinence episodes [at baseline, 4th, 8th, 20th and 32nd week]
data will be collected and evaluated by 72-hour incontinence episodes dairy
- the change from baseline in the amount of urine leakage measured by the 1-hour pad test [at baseline, and the 8th week]
data will be collected by 1-hour pad test
- the change from baseline in the validated Chinese version of International Consultation on Incontinence Questionnaire-Short Form(ICIQ-SF) scores [at baseline, 4th, 8th, 20th and 32nd week]
data will be collected via International Consultation on Incontinence Questionnaire-Short Form(ICIQ-SF). 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.
- the change from baseline in the validated Chinese version of the Overactive Bladder Questionnaire-Short Form scores [at baseline 4th, 8th, 20th and 32nd week]
data will be collected via the Overactive Bladder Questionnaire-Short Form. The higher the total score is, the severer the condition is.
- number of patients with one or more life style change [at the 4th, 8th, 20th and 32nd week]
life style change, such as drinking, diet, weight control and etc, will be evaluated through questionnaire
- incidence rate of any adverse events [this is a case-based data reported by each centre from the start of treatment to the end of follow-up, up to 1 year and 4 months.]
adverse event associated either with or without acupuncture will be documented as soon as it is reported in any centres. The type of conditions, time of on-set and relief, its relation with the intervention, treatment to the adverse event, whether the patient's participation is terminated or not due to the adverse event, etc.
- patients' expectation to treatment [at baseline]
patients will be asked about their expected effect of the treatment via question: In your expectation, how is your incontinence like in a two month time. Five choices will be provided 1) much better; 2) slightly better; 3) I don't know; 4) no change; 5) worse.
- blinding assessment [in 8th week after any acupuncture treatment]
patients will be asked whether they received electroacupuncture or sham acupuncture to assess the effect of blinding
