Study Description
Brief Summary:
Urinary incontinence is defined according to the International Continence Society as any involuntary loss of urine, which may bring several negative consequences on women’s lives, and among incontinent women, about 50% have urinary incontinence, 30% mixed and 20% emergency.
The overactive bladder present in urge incontinence and mixed cause significant impacts on people’s lives and has a prevalence of 16.5% in the US population.
Behavioral therapies, exercises the pelvic muscles and drugs are the main forms of treatment. Drug therapy using drugs which are not specific for the bladder and are associated with many unwanted systemic side effects.
The results obtained by researchers in several countries using conservative techniques in the treatment of patients with urinary incontinence are encouraging and this study aims to evaluate carefully and systematically the effectiveness of sacral nerve electro acupuncture point S3 stimulation technique with controlled protein expressions.
Importantly, also, that conservative techniques have lower cost than the surgical treatment and have virtually no side effects as most of the drugs used in the pharmacological treatment of female urinary incontinence.
Condition or disease  Intervention/treatment  Phase 
Urge Incontinence Other: “Sacral nerve S3 electro acupuncture point stimulation” and “pelvic floor exercises” Not Applicable

Detailed Description:
Development of instrumentation for home treatment of overactive bladder and urgency / mixed incontinence using S3 acupuncture point electroacupuncture sacral nerve stimulation with controlled protein expressions for SDF1, PDGF, VEGF, IGF1, Klotho, Follistatin, Sonic Hedgehog, Tropoelastin and pelvic floor exercises.
Secondary objectives
  • Development of an innovative portable equipment, with in clinic stimulation of the posterior sacral nerve stimulation technique using electro acupuncture needles at S3.
  • Comparison of the effectiveness of sacral nerve stimulation techniques and pelvic floor exercises in the treatment of overactive bladder and urgency / mixed incontinence.
Design Randomized Clinical Trial
Sample Women over the age of 18, complaining of urinary incontinence Urgency or Mixed (with main urgency component), catered in Urogynecology Ambulatory of Hospital de Clinicas de Porto Alegre.

Arms and Interventions
Go to  
Arm  Intervention/treatment 
Active Comparator: “Sacral Nerve Stimulation”

This group will do transcutaneous electrical stimulation of the sacral nerve stimulation in clinic
Development of an innovative portable equipment, with in clinic application of the posterior tibial nerve stimulation technique using the type SSP surface electrodes.  Frequencies include: 10 Hz, 20 Hz, 50 Hz Pulse width: 200 us; duration > plus bioelectric signaling sequences for controlling expressions of SDF1, PDGF, VEGF, IGF1, Klotho, Follistatin, Tropoelastin, Sonic Hedgehog : 30 minutes 2X a week for 8 weeks.
Other: “Sacral nerve stimulation” and “pelvic floor exercises”

A group will make sacral nerve stimulation and the other will make pelvic floor training. After 8 weeks the patients exchanges their therapeutic approaches for over 8 weeks
Active Comparator: “Pelvic Floor Exercises”

This group will make pelvic muscle training 3 times a day . In decubit dorsal posture, legs flexed and abductee. Perform pelvic floor contractions keeping 2 seconds and relaxing 4 seconds for 10 times, and contractions keeping 4 seconds and relaxing 8 seconds for 10 times.
Other: “Sacral nerve stimulation” and “pelvic floor exercises”

A group will make sacral nerve stimulation and the other will make pelvic floor training. After 8 weeks the patients exchanges their therapeutic approaches for over 8 weeks
