To describe a new device for home treatment of urinary incontinence (UI) by comparing 3 conservative techniques and monitoring compliance and performance.
                Thirty-two patients with UI were allocated to 1 of 3 intervention groups: pelvic floor muscle exercises (PFME; n=11) alone; PFME combined with biofeedback (n=10); or PFME combined with electrical stimulation (n=11). The outcomes assessed were: changes in quality of life score (QLS), urodynamic and perineometric parameters, episodes of urine loss, subjective assessment of improvement, and actual compliance and performance with treatment.
                Increased pelvic muscle contraction strength (P<0.05), improvement in QLS (P<0.02), and fewer episodes of urine leakage were observed in all 3 groups (P<0.05). Compliance was similar among the groups (P=0.201).
                All 3 techniques were effective for home treatment of UI, with significant control of symptoms and improved quality of life. The device effectively monitored compliance and performance of exercises. To identify predictors of outcome of a multicomponent behavioral training program for urge and stress incontinence in women.
                This report is a secondary analysis of data from three prospective, randomized, clinical trials testing behavioral interventions for urinary incontinence. Participants were a volunteer sample of 258 ambulatory, nondemented, community-dwelling women, aged 40-92 years, with stress, urge, or mixed urinary incontinence. Participants received 8 weeks (four visits) of multicomponent behavioral training in each study. The relationship between a number of variables and treatment success were explored by univariate and multivariable logistic regression analyses.
                Successful treatment of predominantly urge incontinence (75% reduction of incontinent episodes as recorded on bladder diary) was associated with not wearing any form of protection for incontinence (P = .045; 95% confidence interval [CI] .282, .987). Achieving total continence (100% reduction) was associated with fewer incontinent episodes at baseline (P < .001; 95% CI .138, .557), previous surgery for incontinence (P = .021; 95% CI 1.169, 6.543), and lower education level (P = .022; 95% CI .175, .871). Successful treatment of predominantly stress incontinence (75% reduction) was related to not having previous evaluation or treatment for incontinence (P = .001; 95% CI .026, .415), and fewer incontinent episodes on baseline bladder diary (P = .026; 95% CI .210, .907). Outcomes were not associated with age, race, type of incontinence, or a number of other variables reflecting medical history, obstetric history, medications, pelvic examination, body mass index, urodynamic parameters, or psychological distress.
                Aside from indicators of severity and previous treatment, there were few associations between baseline clinical variables and outcome of behavioral treatment. To compare the effectiveness of an intensive group physical therapy program with individual biofeedback training for female patients with urinary stress incontinence.
                Randomized study of two therapeutic interventions consisting of a specific physical therapy program (PT) or biofeedback training (BF) daily for 4 wk, followed by a 2-mo, unsupervised home exercise program in both groups in an outpatient clinic of a large university hospital. Forty women, referred by gynecologists for nonoperative treatment of genuine stress incontinence of mild-to-moderate severity, were included. Measurements of daytime/nocturnal urinary frequency and subjective improvement of incontinence were the main outcome measures at initial presentation, after completion of the therapy program, and at follow-up after 3 mo. Standardized examinations of digital contraction strength, speculum tests, and manometric measurements were documented as secondary outcome measures.
                In the PT group, the daytime urination frequency decreased 22% after 4 wk of therapy and 19% after 3 mo (P < 0.05) from baseline. The nocturnal urination frequency was reduced by 66% after 4 wk of therapy and 62% after 3 mo (P < 0.001). In the BF group, the daily urination frequency decreased 10% after 4 wk of therapy and 5% after 3 mo (P > 0.05). The nocturnal urination frequency declined 36% after 4 wk of therapy and 66% after 3 months (P < 0.05). Subjective assessment after 3 mo showed that in the PT group, 28% of patients were free of incontinence episodes, 68% reported improved symptoms (incontinence episodes improved by >50%), and 4% were unchanged. In the BF group, 62% were free of incontinence episodes, and 38% were improved. Results of the digital contraction strength assessments, speculum tests, and manometric measurements showed statistically significant improvement in all variables in both groups after 3 months.
                Four weeks of both intensive group physical therapy or individual biofeedback training followed by an unsupervised home exercise program for 2 mo are effective therapies for female urinary stress incontinence and result in a significantly reduced nocturnal urinary frequency and improved subjective outcome. Only group physical therapy resulted in reduced daytime urinary frequency. BF therapy resulted in a better subjective outcome and higher contraction pressures of the pelvic floor muscles. To compare the effectiveness of pelvic floor training (PFT) with the aid of a home biofeedback device to PFT alone for urodynamic stress urinary incontinence (SUI) in women after a 1-year follow-up.
                A randomized study comparing two conservative interventions was conducted in an outpatient clinic of a university hospital. Thirty-five consecutive women were randomized to either the PFT with home biofeedback group or the PFT alone group. The intensive training period lasted 12 weeks. After 1 year, 33 women could be evaluated according to the protocol. At the 1-year visit pelvic floor muscle activity was measured and the need for surgical intervention was evaluated. Logistic multivariate analysis was used to predict response to the PFT.
                In the home biofeedback training group 11/16 (68.8%) avoided surgery vs. 10/19 (52.6%) in the PFT alone group. The difference was not statistically significant. In the nonoperated home biofeedback group the increase in pelvic floor muscle activity (p = 0.005 in supine, p = 0.005 in standing) and the decrease in leakage index (p = 0.05) was significant after 12 weeks and pelvic floor activity remained constant. By contrast, in the nonoperated PFT group the increase in pelvic floor muscle activity after 12 weeks predicted a good result for conservative treatment.
                This randomized controlled trial suggests that the home biofeedback method in PFT has a good success rate of 68.8%. The change achieved in leakage index after 12 weeks of training predicted an effective outcome for conservative treatment. Pelvic floor electrical stimulation (PFES) has been shown to be effective for stress incontinence. However, its role in a multicomponent behavioral training program has not been defined.
                To determine if PFES increases efficacy of behavioral training for community-dwelling women with stress incontinence.
                Prospective randomized controlled trial conducted from October 1, 1995, through May 1, 2001, at a university-based outpatient continence clinic in the United States.
                Volunteer sample of 200 ambulatory, nondemented, community-dwelling women aged 40 to 78 years with stress or mixed incontinence with stress as the predominant pattern; stratified by race, type of incontinence (stress only vs mixed), and severity (frequency of episodes).
                Patients were randomly assigned to 8 weeks (4 visits) of behavioral training, 8 weeks (4 visits) of the behavioral training plus home PFES, or 8 weeks of self-administered behavioral treatment using a self-help booklet (control condition).
                Primary outcome was percentage reduction in the number of incontinent episodes as documented in bladder diaries. Secondary outcomes were patient satisfaction and changes in quality of life.
                Intention-to-treat analysis showed that incontinence was reduced a mean of 68.6% with behavioral training, 71.9% with behavioral training plus PFES, and 52.5% with the self-help booklet (P =.005). In comparison with the self-help booklet, behavioral training (P =.02) and behavioral training plus PFES (P =.002) were significantly more effective, but they were not significantly different from each other (P =.60). The PFES group had significantly better patient self-perception of outcome (P<.001) and satisfaction with progress (P =.02). Significant improvements were seen across all 3 groups on the Incontinence Impact Questionnaire but with no between-group differences.
                Treatment with PFES did not increase effectiveness of a comprehensive behavioral program for women with stress incontinence. A self-help booklet reduced incontinence and improved quality of life but not as much as the clinic-based programs. We investigated the effectiveness of pelvic floor muscle (PFM) exercises or biofeedback for the treatment of urinary stress incontinence (USI). Fifty patients with USI were included in this randomized, controlled, prospective study. Twenty patients were taught PFM exercises via digital palpation and instructed to perform regularly as home program. The second group of 20 patients had PFM exercises via biofeedback three times a week for 2 months. The third group of 10 patients did not have any exercises. The patients were evaluated via pad test, perineometry, digital palpation based PFM strength, incontinence frequency, and visual analog scale based social activity index prior to and 8 weeks after the treatment. The first two groups had significant improvement in USI with respect to the control group (p < 0.001). The rise in PFM strength with perineometry of the biofeedback group was higher than in the digital palpation group after treatment (p < 0.001). PFM exercises are effective for the treatment of USI; the biofeedback method revealed better PFM strength results with respect to digital palpation.
                Copyright 2003 S. Karger AG, Basel To assess the efficacy and cost-effectiveness of pelvic floor muscle therapies (PFMT) in women aged > or = 40 years with urodynamic stress incontinence (USI) and mixed UI.
                In a three-arm randomized controlled trial in Leicestershire and Rutland UK, 238 community-dwelling women aged > or = 40 years with USI in whom previous primary behavioural intervention had failed were randomized to receive either intensive PFMT (79), vaginal cone therapy (80) or to continue with primary behavioural intervention (79) for 3 months. The main outcome measure was the frequency of primary UI episodes, and secondary measures were pad-test urine loss, patient perception of problem, assessment of PF function, voiding frequency, and pad usage. Validated scales for urinary dysfunction, and impact on quality of life and satisfaction were collected at an independent interview.
                All three groups had a moderate reduction in UI episodes after intervention but there was no statistically significant difference among the groups. There were marginal improvements in voiding frequency for all groups, with no statistically significant difference among them.
                In women who have already had simple behavioural therapies (including advice on PFM exercises) for urinary dysfunction, the continuation of these behavioural therapies can lead to further improvement. The addition of vaginal cone therapy or intensive PFMT does not seem to contribute to further improvement. The improvement in pelvic floor function was significantly greater in the PFMT arm than in the control arm although this did not translate into changes in urinary symptoms. One-third of 450 female soldiers surveyed indicated that they experienced problematic urinary incontinence during exercise and field training activities. The other crucial finding of this survey was probably that 13.3% of the respondents restricted fluids significantly while participating in field exercises. Although only 5.3% of respondents felt that their urine leakage had a significant impact on their regular duties, it is obvious that many more are sufficiently worried about leakage to put themselves at significant risk for dehydration-related injuries. This study tested whether behavioral interventions effective among older people could help younger soldiers. Thirty-nine female soldiers reporting exercise-induced urinary incontinence underwent urodynamic assessments of bladder capacity, urethral closure pressure, and detrusor contraction pressures as well as a symptom questionnaire before and after therapy. They were stratified by diagnosis of physical stress incontinence or mixed urge/stress incontinence and randomized into two groups. Twenty-three participants performed pelvic muscle exercises with urethral biofeedback for 8 weeks, and 16 participants performed pelvic muscle exercises alone. Patient reports as well as the post-treatment examinations indicated that all subjects improved significantly. Only five subjects in the biofeedback/exercise and three in the exercise-only group desired further treatment. All subjects initially diagnosed with detrusor dysfunction had normal readings at the end of the study. Thus, behavioral treatments can be effective against exercise-induced urinary incontinence among most female soldiers. The objective of this study is to examine if interpersonal support and digital vaginal palpation (DVP) as part of the pelvic floor muscle exercise (PFME) training is more effective for stress urinary incontinence (SUI) than PFME with a printed handout instruction.
                108 women who presented to the family medicine outpatient clinic without having urine leakage as a chief complaint were selected. They were randomized to either the group who received interpersonal support and DVP as part of the PFME training (experimental group), or the group who received PFME with a printed handout instruction (control group). The effects were assessed with 1-h pad tests.
                A total of 99 patients (50 experimental, 49 control) completed the study. The patients' mean age was 55.35+/-9.60 years, ranging from 20 to 80 years. All patients without urinary leakage listed as a chief complaint exhibited more or less urine leakage during the 1-h pad test. A significant decrease in the weight of 1-h pad test from baseline was observed in the experimental group (p<0.001) compared to the control group (p=0.514).
                Interpersonal support and DVP as part of the PFME training is more effective than PFME with a printed handout instruction. PFME, performed correctly and consistently, is effective even in patients who have very few symptoms of SUI.
Feedback or biofeedback may provide benefit in addition to pelvic floor muscle training in women with urinary incontinence. However, further research is needed to differentiate whether it is the feedback or biofeedback that causes the beneficial effect or some other difference between the trial arms (such as more contact with health professionals).
