  • Stress test

    12 weeks

    12 weeks

Other Outcomes (1)

Study Arms (2)

Electrical pudendal nerve stimulation

EXPERIMENTAL

At a frequency of 2.5 Hz and an intensity (45\~55 mA) as high as the patient can tolerate without discomfort; 60 minutes three times a week for a total of four weeks

Behavioral: Electrical pudendal nerve stimulation

PFM training with Transvaginal ES

ACTIVE COMPARATOR

PFM training: EMG-biofeedback assisted PFMT was performed by specially trained therapists, 20 min three times a week for a total of four weeks. Patients conduct 30 maximal high intensity PFM contractions for 2-6 sec (with 2-6 sec rest), three sessions a day at home for a total of four weeks. Transvaginal ES: At a current intensity of \< 60 mA (as high as possible to get a contraction) and frequencies of 15 Hz and 85 Hz (alternate 3-min periods of stimulation); 20 min three times a week for a total of four weeks.

Behavioral: PFM trainingBehavioral: Transvaginal ES

Interventions

Four sacral points are selected. The two upper points are located about 1 cm bilateral to the sacrococcygeal joint. On the upper points, a needle of 0.40 Х 100 mm is inserted perpendicularly to a depth of 80 to 90 mm to produce a sensation referred to the urethra or the anus. The locations of the two lower points are about 1 cm bilateral to the tip of the coccyx. On the lower points, a needle of 0.40 Х 100 or 125 mm is inserted obliquely towards the ischiorectal fossa to a depth of 90 to 110 mm to produce a sensation referred to the urethra. After the sensation referred to the above regions is produced, each of two pairs of electrodes from a G6805-2 Multi-Purpose Health Device is connected with the two ipsilaterally inserted needles.
