Stress Urinary Incontinence Clinical Trial
Official title:
Transcutaneous Mechanical Nerve Stimulation (TMNS) by Vibration in the Treatment of Stress Incontinence and Urge Incontinence
During transcutaneous mechanical nerve stimulation in spinal cord injured men an increase in
pressure was observed in the external urethral sphincter along with an increase in bladder
capacity. In a subsequent study it was demonstrated that Transcutaneous Mechanical Nerve
Stimulation (TMNS) in women could induce pressure increment of the external urethral
sphincter. A pilot study have since shown that after 6 weeks of stimulation 24 out of 33
women suffering from urinary stress incontinence were able to contract their pelvic floor
muscles and had become free of symptoms. Another pilot study has shown promising effect on
the overactive bladder syndrome.
The present study aims to treat urinary incontinence and includes 2 groups of patients with
30 patients in each group: Women suffering from urinary stress incontinence and women
suffering from urge incontinence. A medical vibrator is used and in each group the subjects
will be randomized to vibration treatment or no vibration treatment. All patients will
receive pelvic floor training and all women suffering from urge incontinence will receive
anticholinergic medications.
The stimulation will be performed at the perineum every day for 6 weeks with an amplitude of
2 mm and a frequency of 100 Hz. Results will be evaluated on the basis of questionnaires,
micturition diaries and diaper tests.
If the investigators are able to demonstrate a significant reduction in the incontinence
symptoms in the subjects the investigators asses that vibration can be a way of
reestablishing a normal function of the pelvic floor muscles and bladder function in
incontinent patients.
