Electroacupuncture and UI

Details and patient eligibility

About

The investigators have developed an investigation comparing electroacupuncture with pelvic floor exercises in female urinary incontinence (UI). It is a randomized clinical trial with 71 women with UI and two arms: 37 women received electroacupuncture with pelvic floor exercises and another arm with 34 women who only received pelvic floor exercises. The investigators evaluated the effectiveness using the International consultation on incontinence questionaire-urinary incontinence short form (ICQ-UI SF) Spanish version. The investigators also evaluated the safety of electroacupuncture in our sample.

Full description

The International Continence Society defines urinary incontinence (UI) as the objectively demonstrable involuntary loss of urine. It affects women of any age. UI significantly impairs patients quality of life, limits their autonomy and reduces their self-esteem. The impairment of health-related quality of life due to UI can be even greater than that caused by some chronic diseases such as diabetes or high blood pressure.

It is common for this type of disorder to be significantly associated with depressive symptoms and feelings of anxiety, which end up affecting the physical, psychological, social, cultural and sexual levels.

UI is classified into: Stress or Effort UI (the most frequent), urge UI and mixed UI. In stress UI, involuntary urine leakage is associated with physical exertion that causes an increase in abdominal pressure; it occurs as a result of a failure in the urethral resistance mechanisms. In urge UI, the involuntary loss of urine is preceded by a compelling desire to urinate; it is due to an increase in urinary bladder contractility. In mixed UI, involuntary urine loss is associated with stress and urge incontinence.

The prevalence of UI varies according to the type of study, the definition and assessment of UI and the characteristics of the population studied (mainly age and sex, with the frequency increasing with age and in women). Worldwide, figures ranging from 5% to 72% have been published; in Spain, the available data range from 15% to 42%, the average prevalence being estimated at 40.6%. The therapeutic approach to UI can be pharmacological (anticholinergics, alpha-blockers and topical estrogens are the most commonly used agents), urological surgery, external devices (such as pessary and urethral occluder), pelvic floor exercises and stimulation by electroacupuncture.

The International Consultation on Urological Diseases recommended pelvic floor muscle training as A level evidence treating simple mild and moderate stress urinary incontinence, which curative rate varies 30% to 60%, although it is a lifelong treatment. Conservative interventions such as pelvic floor muscle training are more likely to be used than drugs or surgery while a woman is pregnant or in the postnatal period.

Pelvic floor exercises for the treatment of urinary incontinence was popularized by Arnold Kegel (1948). It has been recommended in the treatment of stress and mixed urinary incontinence, but has increasingly become part of the treatment of urge UI. It is based on two functions of the pelvic floor muscles: support of the pelvic organs, and a contribution to the urethral sphincter closure mechanism.

From the interpretation of traditional Chinese medicine, the problem of urinary incontinence may be due to a deficiency of energy or "Qi". The pelvic floor, bladder and anal sphincter need significant energy to function properly. This is why it is thought that acupuncture may be a beneficial treatment, as it may increase energy along the urinary tract. UI can be included in two syndromes depending on the signs and symptoms presented by the patient.

Our investigators work compares the effectiveness of electroacupuncture on the point R7 together with pelvic floor exercises versus pelvic floor exercises alone.

71 participants in 2 patient groups

kegel´s exercise (pelvic floor exercise)

Active Comparator group

Description:

A midwife/nurse works with the women according to the following protocol: 1.-identify anal sphincter, and try to raise it from chair (without adding abdominal, thigh, and buttock muscles) with a position of sitting; 2.- identify elevator ani muscle and try to raise vagina from chair (without adding abdominal, thigh, and buttock muscles) with a position of sitting, bent forward, elbows on knees; 3.- contract elevator ani muscle with a position of sitting, lying, and standing; 4.- contract anal sphincter with a position of sitting, lying, and standing. The sessions are conducted by the same midwife/nurse to women in both groups/arms to be performed by the women at home. .
