Efficacy of Biofeedback-Assisted Pelvic Muscle Floor Training and Electrical Stimulation on Women With Stress Urinary Incontinence
Study Details
Study Description
Brief Summary
The pathophysiological mechanism of stress urinary incontinence divides stress urinary incontinence into urethral hypermobility and intrinsic sphincter deficiency. Pelvic floor muscle exercises as first line therapy have been found to be extremely helpful in patients with mild to moderate forms of incontinence. Biofeedback is that used an instrument to record the biological signals ( electrical activity) during a voluntary pelvic floor muscle contraction and present this information back to the woman in auditory or visual form .Electrical stimulation can provide stress urinary incontinence women to detect the pelvic floor muscles, and can also promote the contraction of the pelvic floor muscles and strengthen the muscles. This study assumes that urinary incontinence women with different pathophysiological classifications receiving a pelvic floor muscle training with surface electromyographic biofeedback and electrical stimulation is difference in strengthening of pelvic muscle and improving of symptoms.

Detailed Description
Participant will be assign randomly biofeedback-assisted pelvic floor muscle training (PFMT) group and biofeedback-assisted pelvic floor muscle training (PFMT) combined to electrical stimulation group for two month.The investigators expected that combination therapy will improve the compliance and severity of symptoms in women with stress urinary incontinence.

Outcome Measures
Primary Outcome Measures
- King's Health Questionnaire (KHQ) [Time Frame: through study completion, an average of 8 weeks]
KHQ has 3 parts consisting of 21 items. Part 1 contains general health perception and incontinence impact (one item each). Part 2 contains role limitations, physical limitations, social limitations (two items each), personal relationships, emotions (three items each) and sleep/energy (two items), severity measures (four items).Part 3 is considered as a single item and contains ten responses in relation to frequency, nocturia, urgency,urge, stress, intercourse incontinence, nocturnal enuresis,infections, pain, and difficulty in voiding. The 4 subscales scored between 1 (best) and 4 (worst) in part 1 and 2. The Symptom Severity scale is scored from 0 (best) to 3 (worst) in part 3 .
- A five-item Self-Assessment of Treatment (SAT) [Time Frame: through study completion, an average of 8 weeks.]
to assess improvement and satisfaction with treatment, consists of 1 item. The scale scored between 1 (worst) and 5 (best ) .
- Sandvik urinary incontinence severity test [Time Frame: through study completion, an average of 8 weeks]
The Sandvik test was developed by Sandvik et al to be used as a simple way to calculate severity of urinary incontinence in women. Answer the two questions below and your result will be displayed (Severity Index Score).
- Symptom Indexes for Stress Incontinence [Time Frame: through study completion, an average of 8 weeks]
assigning a grade based on a clinical history of incontinence: grade 1-only on Severe coughing, sneezing, lifting heavy objects, lifting heavy objects, jumping; grade 2-on walking or running; grade 3-on walking, doing housework (eg washing dishes, sweeping the floor), changing posture (eg from standing to squatting or sitting...);grade 4-on Resting state, such as turning over in bed
Secondary Outcome Measures
- Introital and transvaginal ultrasound in the assessment of urogenital and pelvic floor dysfunction [Time Frame: through study completion, an average of 8 weeks]
the transducer is placed over the external urethral orifice with the transducer axis corresponding to the body axis Ultrasound assessment of the bladder and urethra starts in the midsagittal plane. From this position, the transducer can be moved to the left or to the right for additional assessment of the periurethral tissue. The distance between bladder neck and line through the lower edge of the pubic symphysis, and the posterior urethrovesical angle β (angle between urethral axis and bladder floor) are determined at rest and during contraction, coughing, and pressing. Changes in these parameters during contraction and pressing and in particular visual real-time ultrasound assessment serve to evaluate the reactivity of the pelvic floor muscles and the adequacy of the connective tissue supportive structures of the urogenital organs.
- one-hour pad test [Time Frame: through study completion, an average of 8 weeks]
The test is carried out according to the recommendations of the International Continence Society and lasts for one hour and fifteen minutes. It consists in weighing the amount of urine retained in a sanitary napkin after the patient has completed a set of standard exercises, distributed over an hour.
- change of electromyographic activity [Time Frame: through study completion, an average of 8 weeks]
Electromyographic activity of the pelvic floor muscles (PFMs) and the synergistic abdominal muscles (SAMs) during each session of PFMT(µV)
