Intravaginal Electrical Nerve Stimulation in Women With Non-contracting Pelvic Floor

The Intervention group will receive Intravaginal Electrical Nerve Stimulation using Quark® Dualpex equipment, once per week during 8 weeks. The selected current will be biphasic, and the stimulation parameters will be: 50 Hz frequency, pulse width of 200 microseconds, contraction time (Ton) of 5 seconds, relaxation time (Toff) of 10 seconds, intensity of current defined according to the sensitivity (tolerance) of the patient, and total stimulation time of 20 minutes once a week delivered by an experienced Physiotherapist. In the last 10 minutes of each electrical nerve stimulation session women will be requested to perform voluntary PFM contractions along with the contractions induced by the electrical stimulation. Women will not be instructed to perform any aditional exercise or therapy at home.
