Acupuncture for Urinary Incontinence

Percent change in incontinent episodes (measured by self-report electronic bladder diary) at 1 week post-intervention (true or sham acupuncture) relative to baseline.

Percent change in incontinent episodes (measured by self-report electronic bladder diary) 4 weeks post true or sham acupuncture

Percent change in physical health related quality of life measured at 1 week post-intervention (true or sham acupuncture) relative to baseline; measured by the Medical Outcomes Study Short Form-36 (SF-36) Physical Component score. Higher SF-36 Physical Component scores are considered a better outcome.

Percent change in physical health related quality of life measured at 4 weeks post intervention (true or sham acupuncture) relative to baseline; measured by the Medical Outcomes Study Short Form-36 (SF-36) Physical Component score. Positive change indicates an increase in physical health-related quality of life.

Percent change in mental health related quality of life measured at 1 week1 post intervention (true or sham acupuncture) relative to baseline; measured by the Medical Outcomes Study Short Form-36 (SF-36) Mental Health Component score. Higher Mental Health Component scores are considered a better outcome.

Percent change in mental health related quality of life measured at 4 weeks post intervention (true or sham acupuncture) relative to baseline; measured by the Medical Outcomes Study Short Form-36 (SF-36) Mental Health Component score.

Percent change in incontinence specific quality of life at 1 week post intervention (true or sham acupuncture) as measured by the Incontinence Impact Questionnaire. Positive values indicate improvement in incontinence-specific quality of life.

Percent change in incontinence-specific quality of life a 4 weeks post-intervention (true or sham acupuncture) measured by the Incontinence Impact Questionnaire. Positive changes indicate improvement in incontinence-specific quality of life.

Time to relapse in months of participants who completed true acupuncture initially or who crossed-over following sham (offered to all sham participants)

Measured by filling the bladder with sterile fluid until until the subject reported a strong urge to urinate.

Documentation of a diagnostic impression of stress urinary incontinence following urodynamics

Documentation of a diagnostic impression of urge urinary incontinence following urodynamics

Glasses/cups per day of non-caffeinated fluids (including water) at baseline

Duration of urinary incontinence in years

Percentage of acupuncture (true or sham) visits completed as scheduled

Subjects' report of burden (difficulty) associated with the frequency, number and duration of treatment) and the position they had to remain in during the true and sham treatments. Subjects rate the difficulty associated with each of the four aspects of treatment on a 10-point scale ranging from 1 (not at all difficult) to 10 (extremely difficult). The burden score was calculated as the average of the scores on the 4 items with a possible range of 1 to 10 with higher scores indicating greater burden.

The number of participants who were received true acupuncture (as their initial intervention or after initially receiving sham acupuncture) and were eligible to receive a booster (had a 50% or greater reduction in incontinent episodes following true acupuncture) and completed at least one month of follow-up and experienced a 30% or greater increase in incontinent episodes during follow up.

Change in the number of incontinent episodes per day following booster acupuncture

Change in average duration of pelvic floor muscle contraction measured by electromyography. Subjects were instructed to tighten their pelvic floor muscles when prompted and hold the contraction until told to relax (up to 10 seconds). This was repeated three times and the duration of the contraction time was averaged.
