Comparative analysis of biofeedback and physical therapy for treatment of urinary stress incontinence in women

Conservative interventions for treating urinary incontinence in women: an Overview of Cochrane systematic reviews

BACKGROUND

Urinary incontinence (UI) is the involuntary loss of urine and can be caused by several different conditions. The common types of UI are stress (SUI), urgency (UUI) and mixed (MUI). A wide range of interventions can be delivered to reduce the symptoms of UI in women. Conservative interventions are generally recommended as the first line of treatment.

OBJECTIVES

To summarise Cochrane Reviews that assessed the effects of conservative interventions for treating UI in women.

METHODS

We searched the Cochrane Library to January 2021 (CDSR; 2021, Issue 1) and included any Cochrane Review that included studies with women aged 18 years or older with a clinical diagnosis of SUI, UUI or MUI, and investigating a conservative intervention aimed at improving or curing UI. We included reviews that compared a conservative intervention with 'control' (which included placebo, no treatment or usual care), another conservative intervention or another active, but non-conservative, intervention. A stakeholder group informed the selection and synthesis of evidence. Two overview authors independently applied the inclusion criteria, extracted data and judged review quality, resolving disagreements through discussion. Primary outcomes of interest were patient-reported cure or improvement and condition-specific quality of life. We judged the risk of bias in included reviews using the ROBIS tool. We judged the certainty of evidence within the reviews based on the GRADE approach. Evidence relating to SUI, UUI or all types of UI combined (AUI) were synthesised separately. The AUI group included evidence relating to participants with MUI, as well as from studies that combined women with different diagnoses (i.e. SUI, UUI and MUI) and studies in which the type of UI was unclear.

MAIN RESULTS

We included 29 relevant Cochrane Reviews. Seven focused on physical therapies; five on education, behavioural and lifestyle advice; one on mechanical devices; one on acupuncture and one on yoga. Fourteen focused on non-conservative interventions but had a comparison with a conservative intervention. No reviews synthesised evidence relating to psychological therapies. There were 112 unique trials (including 8975 women) that had primary outcome data included in at least one analysis. Stress urinary incontinence (14 reviews) Conservative intervention versus control: there was moderate or high certainty evidence that pelvic floor muscle training (PFMT), PFMT plus biofeedback and cones were more beneficial than control for curing or improving UI. PFMT and intravaginal devices improved quality of life compared to control. One conservative intervention versus another conservative intervention: for cure and improvement of UI, there was moderate or high certainty evidence that: continence pessary plus PFMT was more beneficial than continence pessary alone; PFMT plus educational intervention was more beneficial than cones; more-intensive PFMT was more beneficial than less-intensive PFMT; and PFMT plus an adherence strategy was more beneficial than PFMT alone. There was no moderate or high certainty evidence for quality of life. Urgency urinary incontinence (five reviews) Conservative intervention versus control: there was moderate to high-certainty evidence demonstrating that PFMT plus feedback, PFMT plus biofeedback, electrical stimulation and bladder training were more beneficial than control for curing or improving UI. Women using electrical stimulation plus PFMT had higher quality of life than women in the control group. One conservative intervention versus another conservative intervention: for cure or improvement, there was moderate certainty evidence that electrical stimulation was more effective than laseropuncture. There was high or moderate certainty evidence that PFMT resulted in higher quality of life than electrical stimulation and electrical stimulation plus PFMT resulted in better cure or improvement and higher quality of life than PFMT alone. All types of urinary incontinence (13 reviews) Conservative intervention versus control: there was moderate to high certainty evidence of better cure or improvement with PFMT, electrical stimulation, weight loss and cones compared to control. There was moderate certainty evidence of improved quality of life with PFMT compared to control. One conservative intervention versus another conservative intervention: there was moderate or high certainty evidence of better cure or improvement for PFMT with bladder training than bladder training alone. Likewise, PFMT with more individual health professional supervision was more effective than less contact/supervision and more-intensive PFMT was more beneficial than less-intensive PFMT. There was moderate certainty evidence that PFMT plus bladder training resulted in higher quality of life than bladder training alone.

AUTHORS' CONCLUSIONS

There is high certainty that PFMT is more beneficial than control for all types of UI for outcomes of cure or improvement and quality of life. We are moderately certain that, if PFMT is more intense, more frequent, with individual supervision, with/without combined with behavioural interventions with/without an adherence strategy, effectiveness is improved. We are highly certain that, for cure or improvement, cones are more beneficial than control (but not PFMT) for women with SUI, electrical stimulation is beneficial for women with UUI, and weight loss results in more cure and improvement than control for women with AUI. Most evidence within the included Cochrane Reviews is of low certainty. It is important that future new and updated Cochrane Reviews develop questions that are more clinically useful, avoid multiple overlapping reviews and consult women with UI to further identify outcomes of importance.

Managing anxiety disorders with the neuro-biofeedback method of Brain Boy Universal Professional

Background

Biofeedback is a non-invasive therapeutic method used independently or as an adjunct alongside other methods.

Objective

This study evaluated the efficacy of biofeedback in the treatment of anxiety disorders.

Methods

The sample consisted of 85 individuals with anxiety symptoms who underwent neuro-biofeedback therapy using Brain Boy Universal Professional. Anxiety was assessed by both the Hamilton Rating Scale for Anxiety (HAM-A) and Zung Anxiety Self-Assessment Scale (SAS) before the initiation and after completing ten sessions with biofeedback.

Results

Before biofeedback and based on the HAM-A scale, 27.0% of the individuals showed mild to moderate anxiety, 16.5% medium anxiety, and 56.5% severe anxiety. After the completion of biofeedback, 90.6% of the individuals experienced mild to moderate anxiety, 5.9% medium anxiety, and 3.5% severe anxiety. Based on the SAS scale, before biofeedback, 42.4% of the individuals showed minimal to moderate anxiety, 21.2% marked severe anxiety and 36.5% most extreme anxiety. After the biofeedback, 68.2% of the individuals were within a normal range, 27.1% had minimal to moderate anxiety, 4.7% marked severe anxiety, and none in most extreme anxiety.

Conclusion

Both HAMA-A and SAS scales showed statistically reduced anxiety levels after biofeedback therapy. Thus, the primary symptom of anxiety can be addressed by the biofeedback method.

OUTLET OBSTRUCTED CONSTIPATION AND FECAL INCONTINENCE: IS REHABILITATION TREATMENT THE WAY? MYTH OR REALITY

Pelvic floor rehabilitation aims to address perineal functional and anatomic alterations as well as thoraco-abdominal mechanic dysfunctions leading to procto-urologic diseases like constipation, fecal and urinary incontinence, and pelvic pain. They require a multidimensional approach, with a significant impact on patients quality of life. An exhaustive clinical and instrumental protocol to assess defecation disorders should include clinical and instrumental evaluation as well as several clinical/physiatric parameters. All these parameters must be considered in order to recognize and define any potential factor playing a role in the functional aspects of incontinence, constipation and pelvic pain. After such evaluation, having precisely identified any thoraco-abdomino-perineal anatomic and functional alterations, a pelvi-perineal rehabilitation program can be carried out to correct the abovementioned alterations and to obtain clinical improvement. The success of the rehabilitative process is linked to several factors such as a careful evaluation of the patient, aimed to select the most appropriate and specific targeted rehabilitative therapy, the therapist's scrupulous hard work, especially as regards the patient's emotional and psychic state, and finally the patient's compliance in undertaking the therapy itself, especially at home. These factors may deeply influence the overall outcomes of the rehabilitative therapies, ranging from "real" success to illusion "myth".

Evaluation of applying Kinesio taping in children with urinary incontinence

INTRODUCTION

Physiotherapeutic methods, used in patients with urinary incontinence, are recommended and acknowledged treatment methods. They include pelvic floor muscle exercises, electrical stimulation, magnetic field, acupuncture, and biofeedback. However, the influence of Kinesio taping (KT) applications is not known. The aim of this work was to assess the influence of the KT method on the number of incontinence incidents in children. Additionally, children included in the research were given a depression level test to assess their mental state and how it is influenced by incontinence.

MATERIAL AND METHODS

The study included 62 children (37 boys and 25 girls), aged 7-14 years, diagnosed as having night urinary incontinence and frequent daytime incontinence (daytime wetting). Study participants were randomly allocated to the research group, in which KT was applied, or the control group in which a placebo was used. The main outcome measure was the number of incontinence incidents.

RESULT

The analysis of study results indicated that there was a statistically significant decrease (p < 0.001) in the number of incontinence incidents after KT was applied among children in the research group compared with those in the control group. After 4 days of KT application the number decreased by half within 24 h (Figure).

DISCUSSION

As can be seen from the analysis of the literature on urinary incontinence therapy, several physiotherapeutic methods are described. They are not merely based on a single strategy but include combinations of methods. To our knowledge, the method described in our work is a pioneer method, previously not applied on its own. It is, however, limited by a relatively small number of research participants, although it took 29 months to gather the group for the research. Additionally, the research based on the principle that children with up to threw incontinence episodes per day were given KT applications every 3 days (72 h per session), whereas children with more frequent incontinence episodes were given KT applications every day (24 h per session). It seems that the principle should be that all children are given KT applications with the same frequency. Perhaps it could be interesting to compare the effects between groups with different frequency. Nevertheless, we believe that the results obtained in this research are of interest in the context of possibility to use KT for urinary incontinence in children.

CONCLUSION

The KT method may serve as an effective complementary form of physiotherapy for children with urinary incontinence.

Effect of electromyographic biofeedback as an add-on to pelvic floor muscle exercises on neuromuscular outcomes and quality of life in postmenopausal women with stress urinary incontinence: A randomized controlled trial

AIMS

To compare the efficacy of pelvic floor muscle exercises (PFME) with and without electromyographic biofeedback (BF) in increasing muscle strength, improving myoelectric activity, and improving pre-contraction and quality of life in postmenopausal women with stress urinary incontinence.

METHODS

Randomized controlled trial of 49 postmenopausal women with stress urinary incontinence. Participants were allocated across three groups: control, PFME alone, and PFME + BF. Forty-five women completed the study (14 control, 15 PFME, 16 PFME + BF; mean age 58.26 years). Outcome assessment was carried out using digital palpation (modified Oxford grading scale), electromyography, and the International Consultation Incontinence Questionnaire-Short Form (ICIQ-SF) quality of life instrument. The treatment protocol consisted of eight twice-weekly, 20-min one-on-one sessions. Controls were assessed only at baseline and after 1 month.

RESULTS

The PFME and PFME + BF groups exhibited significant increases in muscle strength (Oxford scale) (P < 0.0001), precontraction while coughing (P < 0.0001), maximum voluntary contraction, duration of endurance contraction, and ICIQ-SF scores (P < 0.0001). PFME + BF was associated with significantly superior improvement of muscle strength, precontraction while coughing, maximum voluntary contraction, and duration of endurance contraction as compared to PFME alone (P < 0.05).

CONCLUSIONS

This preliminary study suggests that pelvic floor muscle training, with and without biofeedback, is associated with increased muscle strength, myoelectric activity, precontraction of pelvic floor muscles, and improved quality of life in postmenopausal women with stress urinary incontinence.

Nonsurgical Treatment of Urinary Incontinence in Elderly Women

Urinary incontinence is a prevalent condition in elderly women with significant associated morbidity. Incontinence can by grouped into several types: stress incontinence, urgency incontinence, overflow incontinence, functional incontinence, and mixed urinary incontinence. Careful evaluation, including history and physical examination, is critical to making the correct diagnosis and guiding therapy. A variety of nonsurgical treatments, including behavioral therapies, pelvic floor muscle exercise, medications, and other treatments, are available; can be successful for many older women; and may preclude the need for surgery. Working closely with the patient, understanding her goals of care, and targeting treatments accordingly are essential for success.

Clinical Guideline for Female Lower Urinary Tract Symptoms

The "Japanese Clinical Guideline for Female Lower Urinary Tract Symptoms," published in Japan in November 2013, contains two algorithms (a primary and a specialized treatment algorithm) that are novel worldwide as they cover female lower urinary tract symptoms other than urinary incontinence. For primary treatment, necessary types of evaluation include querying the patient regarding symptoms and medical history, examining physical findings, and performing urinalysis. The types of evaluations that should be performed for select cases include evaluation with symptom/quality of life (QOL) questionnaires, urination records, residual urine measurement, urine cytology, urine culture, serum creatinine measurement, and ultrasonography. If the main symptoms are voiding/post-voiding, specialized treatment should be considered because multiple conditions may be involved. When storage difficulties are the main symptoms, the patient should be assessed using the primary algorithm. When conditions such as overactive bladder or stress incontinence are diagnosed and treatment is administered, but sufficient improvement is not achieved, the specialized algorithm should be considered. In case of specialized treatment, physiological re-evaluation, urinary tract/pelvic imaging evaluation, and urodynamic testing are conducted for conditions such as refractory overactive bladder and stress incontinence. There are two causes of voiding/post-voiding symptoms: lower urinary tract obstruction and detrusor underactivity. Lower urinary tract obstruction caused by pelvic organ prolapse may be improved by surgery.

The effect of pelvic floor muscle training in urinary incontinent elderly women: a sistematic review

Introduction The International Continence Society (ICS) determines that the pelvic floor muscles training (PFMT) is the first-choice treatment of urinary symptoms in women. Objective The aim of this study was to systematize randomized controlled clinical trials that address the effects of PFMT in the treatment of urinary symptoms in older women using objective outcome measures. Method Systematic review search was performed eletronic the following databases: Medline, Pubmed, Lilacs, PEDro and manual research conducted in the references of the studies. Were considered eligible women aged over 60 years who performed PFMT in isolation, without the involvement of another technique. The PFMT performed in clinic or at home, with or without the supervision of a therapist and with or without the use of biofeedback as an adjunct. Considered as outcome measures urodynamic studies, voiding diary that assesses daytime urinary frequency, nocturnal urinary frequency, urinary incontinence and exchange absorbent, and, finally, the absorbent test that quantifies loss urinary grams. The assessment of methodological quality of the studies was conducted by PEDro scale. Results Three studies were reviewed in full. Only one trial was rated high methodological quality. There was significant improvement in urinary symptoms after treatment proposed in the three selected studies. Conclusion Considering the studies available so far are weak the evidence for the use of PFMT in the treatment of urinary symptoms in elderly women.

Short-term outcomes after rehabilitation treatment in patients selected by a novel rehabilitation score system (Brusciano score) with or without previous stapled transanal rectal resection (STARR) for rectal outlet obstruction

PURPOSE

The purpose of this study was to examine short-term outcomes of rehabilitation treatment in patients with or without previous stapled transanal resection (STARR) for rectal outlet obstruction by using a novel rehabilitation score system (Brusciano score).

METHODS

This is a retrospective cohort study conducted at a single tertiary referral institution including all patients with chronic functional constipation admitted to the outpatient unit from 2004 to 2009.

RESULTS

Among 330 consecutive patients, 247 (74.8 %) (204 females and 43 males) showing a significantly higher rehabilitation score (mean of 15.7 ± 1.8; range, 7-25) than healthy controls (mean, 3.2 ± 1.2; range 2-6) (p < .0001) were selected for rehabilitation. Of the 247 patients evaluated, group A (no previous surgery) consisted of 170 patients (53 males; mean age, 44.8 ± 12.9 years; range, 19-80) of which 38 presented mixed constipation, whereas group B (previous surgery) consisted of 77 patients (18 males; mean age, 47.0 ± 11.2 years; range, 22-81). The Brusciano score, Agachan-Wexner score and quality of life improved in both groups of patients after treatment. Better improvements of Brusciano and Agachan-Wexner scores were observed in patients with previous STARR (group B).

CONCLUSIONS

The rehabilitation score system employed in this study seems to be a useful tool in selecting and assessing the outcome of patients who might benefit from rehabilitation treatment. Constipation and quality of life were significantly improved by the rehabilitation treatment. Further studies are needed to clarify either the impact of rehabilitation treatment on long-term outcome of patients treated for rectal outlet obstruction or its role in those who develop problems over time.

Randomized controlled trial of pelvic floor muscle training with or without biofeedback for urinary incontinence

INTRODUCTION AND HYPOTHESIS

To compare the effects of pelvic floor muscle training (PFMT), with or without biofeedback (BF), for stress urinary incontinence (SUI), focusing on condition-specific quality of life (QOL) outcomes.

METHODS

Women with SUI were randomized to PFMT with BF (BF group, n = 23) or without BF (PFMT group, n = 23) for 12 weeks. As primary outcome measures, subjective symptoms and QOL were assessed by the King's Health Questionnaire (KHQ) and International Consultation on Incontinence Questionnaire-Short Form (ICIQ-SF). A voiding diary, 1-h pad test, and measurement of PFM strength were secondary outcome measures. Changes in the primary and secondary outcomes were assessed before and after 12 weeks' exercise training.

RESULTS

Of the 9 domains of the KHQ, the scores of 5 significantly decreased in the PFMT group, and the scores of 7 significantly decreased in the BF group. All ICIQ-SF items and the total score significantly decreased in both groups after therapy. The number of incontinence episodes significantly decreased in the PFMT group, and tended to decrease in the BF group, but this was not significant (P = 0.054). The leakage volume in the 1-h pad test tended to decrease in both groups, but was not significant. Maximum vaginal squeeze pressure significantly increased in both groups. There were no significant inter-group differences in the changes in any of the parameters assessed.

CONCLUSIONS

The results indicate that PFMT is effective for treating SUI. There is no apparent add-on effect of BF training in short-term follow-up.

Vaginal cone therapy in patients with stress urinary incontinence

PURPOSE

The aim of this study is to assess the effectiveness of the vaginal cone usage in patients with stress urinary incontinence (SUI) treated by hormone replacement therapy (HRT).

METHODS

In this prospective controlled study, vaginal cone therapy is proposed to 22 postmenopausal patients with SUI having HRT who were admitted to Istanbul University, Faculty of Medicine Urogynecology Division. The vaginal cone therapy protocol consisted of one 40-min session per day over a 12-week period at standing position, and to push back the vaginal cone if they feel it slide for 15 times. Control group consisted of ten postmenopausal patients receiving only HRT. For the two groups, perineometry value, pad test, and 3 days average number of incontinence were assessed at the beginning and after 2 months of treatment.

RESULTS

In the vaginal cone group, in all parameters a statistically significant difference was observed toward improvement as compared to baseline (p < 0.01); there were no significant differences (p > 0.05) in the HRT group. While comparing between the mean differences of two groups, the average number of urinary leakage was decreased and perineometry value was statistically increased (t = 3.74, p < 0.001; t = 3.24, p < 0.01) in vaginal cone group rather than in the HRT group which was calculated from the urinary diary.

CONCLUSIONS

Vaginal cone could be an effective method of treatment in patients with SUI and may be a preferable treatment for patients who have problem to come to hospital and want to work independently at home.

Biofeedback for the treatment of female pelvic floor muscle dysfunction: a systematic review and meta-analysis

Biofeedback (BF) has been widely used in the treatment of pelvic floor dysfunctions, mainly by promoting patient learning about muscle contraction with no side effects. However, its effectiveness remains poorly understood with some studies suggesting that BF offers no advantage over the isolated pelvic floor muscle training (PFMT). The main objective of this study was to systematically review available randomized controlled trials assessing the effectiveness of BF in female pelvic floor dysfunction treatment. Trials were electronically searched and rated for quality by use of the PEDro scale (values of 0-10). Randomized controlled trials assessing the training of pelvic floor muscle (PFM) using BF in women with PFM dysfunction were selected. Outcomes were converted to a scale ranging from 0 to 100. Trials were pooled with software used to prepare and update Cochrane reviews. Results are presented as weighted mean differences with 95 % confidence intervals (CI). Twenty-two trials with 1,469 patients that analyzed BF in the treatment of urinary, anorectal, and/or sexual dysfunctions were included. PFMT alone led to a superior but not significant difference in the function of PFM when compared to PFMT with BF, by using vaginal measurement in the short and intermediate term: 9.89 (95 % CI -5.05 to 24.83) and 15.03 (95 % CI -9.71 to 39.78), respectively. We found a few and nonhomogeneous studies addressing anorectal and sexual function, which do not provide the cure rate calculations. Limitations of this review are the low quality and heterogeneity of the studies, involving the usage of distinct protocols of interventions, and various and different outcome measures. The results of this systematic review suggest that PFMT with BF is not more effective than other conservative treatments for female PFM dysfunction.

Feedback or biofeedback to augment pelvic floor muscle training for urinary incontinence in women

BACKGROUND

Pelvic floor muscle training (PFMT) is an effective treatment for stress urinary incontinence in women. Whilst most of the PFMT trials have been done in women with stress urinary incontinence, there is also some trial evidence that PFMT is effective for urgency urinary incontinence and mixed urinary incontinence. Feedback or biofeedback are common adjuncts used along with PFMT to help teach a voluntary pelvic floor muscle contraction or to improve training performance.

OBJECTIVES

To determine whether feedback or biofeedback adds further benefit to PFMT for women with urinary incontinence.To compare the effectiveness of different forms of feedback or biofeedback.

SEARCH STRATEGY

We searched the Cochrane Incontinence Group Specialised Trials Register (searched 13 May 2010) and the reference lists of relevant articles.

SELECTION CRITERIA

Randomised or quasi-randomised trials in women with stress, urgency or mixed urinary incontinence (based on symptoms, signs or urodynamics). At least two arms of the trials included PFMT. In addition, at least one arm included verbal feedback or device-mediated biofeedback.

DATA COLLECTION AND ANALYSIS

Trials were independently assessed for eligibility and risk of bias. Data were extracted by two reviewers and cross-checked. Disagreements were resolved by discussion or the opinion of a third reviewer. Data analysis was conducted in accordance with the Cochrane Handbook for Systematic Reviews of Intervention (version 5.1.0). Analysis within subgroups was based on whether there was a difference in PFMT between the two arms that had been compared.

MAIN RESULTS

Twenty four trials involving 1583 women met the inclusion criteria; 17 trials contributed data to analysis for one of the primary outcomes. All trials contributed data to one or more of the secondary outcomes. Women who received biofeedback were significantly more likely to report that their urinary incontinence was cured or improved compared to those who received PFMT alone (risk ratio 0.75 , 95% confidence interval 0.66 to 0.86). However, it was common for women in the biofeedback arms to have more contact with the health professional than those in the non-biofeedback arms. Many trials were at moderate to high risk of bias, based on trial reports. There was much variety in the regimens proposed for adding feedback or biofeedback to PFMT alone, and it was often not clear what the actual intervention comprised or what the purpose of the intervention was.

AUTHORS' CONCLUSIONS

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).

Clinical and instrumental parameters in patients with constipation and incontinence: their potential implications in the functional aspects of these disorders

PURPOSE

The aims of this study were to evaluate several clinical and instrumental parameters in a large number of patients with constipation and incontinence as well as in healthy controls and discuss their potential implications in the functional aspects of these disorders.

METHODS

Eighty-four constipated and 38 incontinent patients and 45 healthy controls were submitted to a protocol based on proctologic examination, clinico-physiatric assessment, and instrumental evaluation.

RESULTS

Constipated and incontinent patients had significantly worse lumbar lordosis as well as lower rate in the presence of perineal defense reflex than controls. Constipated but not incontinent patients had a lower rate of puborectalis relaxation than controls. Furthermore, worse pubococcygeal tests and a higher rate of muscle synergies presence, either agonist or antagonist, were observed in both constipated and incontinent patients compared to controls.

CONCLUSIONS

This study has demonstrated strong correlations between physiatric disorders and the symptoms of constipation and incontinence. Further studies designed to demonstrate a causal relationship between these parameters and the success of a specific treatment of the physiatric disorders on the proctology symptoms are warranted.

A contextual model of pelvic floor muscle defects in female stress urinary incontinence: a rationale for physiotherapy treatment

On the basis of the current literature, we describe a model of structural defects in stress urinary incontinence (SUI) and how physiotherapy for SUI can affect each component of the model with reference to the relevant anatomy and pathophysiology. This model of SUI involves four primary structural defects: (1) increased tonic stress on the pelvic fascia due to pelvic floor muscle (PFM) tears; (2) fascial tearing due to PFM denervation; (3) fascial weakness resulting from tears; and (4) inefficient PFM contraction due to altered motor control. These four components interact to collectively weaken urethral closure and allow urine leakage under conditions of increased intra-abdominal pressure. Physiotherapy can strengthen the PFM and may improve the efficiency and/or timing of PFM contractions to reduce or eliminate SUI. It is worthwhile for motivated women with SUI to try PFM exercise therapy as a first approach to treatment. Women need to be individually instructed to ensure that they correctly perform PFM contractions and that they can monitor their own performance. Long-term, high-intensity exercise, including home exercise, is necessary to achieve maximum effect. Under these conditions the improvement in urinary continence with PFM exercise can be complete and enduring.

Management of stress urinary incontinence with surface electromyography-assisted biofeedback in women of reproductive age

BACKGROUND AND PURPOSE

Although surgery has been widely accepted as the treatment of choice for stress urinary incontinence (SUI), there has recently been an increased interest in the conservative management of this condition. The aims of this study were to test the ability of a biofeedback-assisted pelvic-floor muscle exercise (PFME) program to affect symptoms of SUI in premenopausal women and to evaluate a training program that might lead to successful outcomes in a relatively limited number of sessions.

SUBJECTS

Twenty-six women with SUI were treated with PFME with surface electromyography (sEMG)-assisted biofeedback. All participants were of reproductive age and were treated individually for 12 sessions.

METHODS

results were evaluated with a 7-day voiding diary, a 1-hour pad test, pelvic-floor muscle strength measurements, sEMG amplitudes, a leakage index, and a quality-of-life questionnaire. These variables were compared before and after the intervention.

RESULTS

The frequency of urine loss, the occurrence of nocturia, and the number of pads required decreased significantly after the intervention. Objective cure was found in 61.5% of women. There was a significant improvement in the quality of life, in pelvic-floor muscle strength, and in the sEMG amplitudes of all contractions throughout the intervention.

DISCUSSION AND CONCLUSION

A relatively short-term intervention of PFME with sEMG-assisted biofeedback appeared to be helpful in relieving symptoms of SUI in premenopausal women and represents a reasonable conservative management option.

Dilemmas in the management of female stress incontinence: the role of pelvic floor muscle training

Treatment options for female stress urinary incontinence include pelvic floor muscle training, lifestyle interventions, bladder retraining, pharmacotherapy, anti-incontinence devices and surgery. Several consensus statements recommend pelvic floor muscle training as first line treatment. The aim of this review is to analyse all the currently available data and propose a treatment algorithm for clinical practice. A literature-based critical presentation of all treatment modalities, methods of assessing efficacy and comparison between them using a patient-centered approach was made. Many of the studies are observational, non-randomized with several methodological problems that lead to confusion. Emphasis was made to high quality randomized trials. The proposed treatment algorithm established only on evidence-based data. Management strategy however, must identify patient expectations and involve them in the decision-making more than traditional measures of treatment success.

Pelvic Floor Muscle Biofeedback in the Treatment of Urinary Incontinence: A Literature Review

Biofeedback is efficacious in the training of the pelvic floor musculature in order to enhance continence. This article reviews the anatomy and physiology of micturition as the underlying rationale for pelvic floor muscle biofeedback in the treatment of urinary incontinence. It critically reviews 28 studies published in peer reviewed journals from 1975 to 2005 that were prospective, randomized studies with parametric statistical analyses, operationally defined patient selection criteria, treatment protocols and outcome measures. The overall mean treatment improvement for patients undergoing biofeedback for urinary incontinence was 72.61%. In 21 of 35 (60%) paired comparisons, biofeedback demonstrated superior symptomatic outcome to control or alternate treatment groups. Larger studies and a standardization of technology and methodology are required for more conclusive determinations.

Pelvic floor exercises with biofeedback for stress urinary incontinence

OBJECTIVE

Prospective study to objectively evaluate the benefits of pelvic floor strengthening exercises associated to biofeedback for the treatment of stress urinary incontinence.

MATERIALS AND METHODS

Fourteen patients diagnosed with stress urinary incontinence (SUI) were selected for this study. All patients underwent a pelvic floor training associated to biofeedback for 12 consecutive weeks. Urodynamic tests, pad test and bladder diary were analyzed at the beginning of the study, at the end and after 3 months. The King's Health Questionnaire (KHQ) was applied before and after treatment to assess the impact in the quality of life.

RESULTS

There was a significant reduction in the pad weight (from 14.21 g to 1 g), number of urinary leakage episodes (from 8.14 per day to 2.57 per day) and daytime frequency (from 7.93 per day to 5.85 per day). At urodynamics the authors observed a significant increase in Valsalva leak-point pressure (from 103.93 cm H2O to 139.14 cm H2O), cistometric capacity (from 249.29 mL to 336.43 mL, p = 0.0015) and bladder volume at first desire to void (from 145 mL to 215.71 mL). Those differences were kept during the first 3 months of follow up. The KHQ revealed significant differences except in the case of ''general health perception'', which covers health in general and not exclusively urinary incontinence.

CONCLUSION

Treatment of SUI with pelvic floor exercises associated to biofeedback caused significant changes in the parameters analyzed, with maintenance of good results 3 months after treatment.

Pelvic floor muscle training and adjunctive therapies for the treatment of stress urinary incontinence in women: a systematic review

BACKGROUND

Stress urinary incontinence (SUI) is a prevalent and costly condition which may be treated surgically or by physical therapy. The aim of this review was to systematically assess the literature and present the best available evidence for the efficacy and effectiveness of pelvic floor muscle training (PFMT) performed alone and together with adjunctive therapies (eg biofeedback, electrical stimulation, vaginal cones) for the treatment of female SUI.

METHODS

All major electronic sources of relevant information were systematically searched to identify peer-reviewed English language abstracts or papers published between 1995 and 2005. Randomised controlled trials (RCTs) and other study designs eg non-randomised trials, cohort studies, case series, were considered for this review in order to source all the available evidence relevant to clinical practice. Studies of adult women with a urodynamic or clinical diagnosis of SUI were eligible for inclusion. Excluded were studies of women who were pregnant, immediately post-partum or with a diagnosis of mixed or urge incontinence. Studies with a PFMT protocol alone and in combination with adjunctive physical therapies were considered. Two independent reviewers assessed the eligibility of each study, its level of evidence and the methodological quality. Due to the heterogeneity of study designs, the results are presented in narrative format.

RESULTS

Twenty four studies, including 17 RCTs and seven non-RCTs, met the inclusion criteria. The methodological quality of the studies varied but lower quality scores did not necessarily indicate studies from lower levels of evidence. This review found consistent evidence from a number of high quality RCTs that PFMT alone and in combination with adjunctive therapies is effective treatment for women with SUI with rates of 'cure' and 'cure/improvement' up to 73% and 97% respectively. The contribution of adjunctive therapies is unclear and there is limited evidence about treatment outcomes in primary care settings.

CONCLUSION

There is strong evidence for the efficacy of physical therapy for the treatment for SUI in women but further high quality studies are needed to evaluate the optimal treatment programs and training protocols in subgroups of women and their effectiveness in clinical practice.

The effect of home biofeedback training on stress incontinence

BACKGROUND

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.

METHODS

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.

RESULTS

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.

CONCLUSIONS

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.

Behavioral treatment options for urinary incontinence

Behavioral treatments improve bladder control by changing the incontinent patient's behavior, especially his or her voiding habits, and by teaching skills for preventing urine loss. These treatments are effective for most outpatient men and women with stress, urge, or mixed incontinence. The average reduction in the frequency of incontinence ranges from 57% to 86%. In long-term care settings, treatment is generally more challenging and yields more modest results. The advantages of behavioral interventions include the absence of side-effects, patient comfort, and high levels of patient satisfaction. Although most patients who receive behavioral treatment achieve significant improvement, most are not completely dry. Thus, there is a need for research to explore ways to enhance the effectiveness of these conservative therapies. Combining behavioral treatment with other treatments may have additive effects. Research is also needed to understand better the mechanisms of therapeutic change, the best methods for teaching pelvic floor muscle control, the optimal exercise regimens, the predictors of outcome, and the efficacy of behavioral treatments in men. Although behavioral interventions are more accepted today than 20 years ago, they are still not widely available or integrated into most clinical practices, and we know little of how effective they will be in these settings. Thus, it will be important to develop and evaluate creative modes of delivery, such as group intervention (especially by nonphysician providers), in a variety of clinical settings.

Behavioral intervention: the first-line treatment for women with urinary incontinence

Urinary incontinence is a women's health problem that imposes major consequences for personal quality of life and for national health care costs. The evidence base for the efficacy of the behavioral interventions of bladder training and pelvic muscle training to treat urinary incontinence in women is strong. Bladder and pelvic muscle training should be considered as basic health promotion education for all women. Screening for incontinence should be a routine component of women's health care and bladder and pelvic muscle training should be prescribed by clinicians as a first-line treatment for women who screen positive. This article summarizes the relevant research and outlines intervention strategies that clinicians can readily translate into everyday practice.

Device to promote pelvic floor muscle training for stress incontinence

AIM

Many patients with stress urinary incontinence do not have enough motivation to continue pelvic floor muscle training (PFMT) by themselves. Therefore, a device was created to support PFMT, and its effect was examined.

METHODS

Forty-six women with stress urinary incontinence were assigned to a control group or a device group in order of presentation. A pamphlet on PFMT was given to control patients, while the same pamphlet plus the device and instructions on its use were given to patients in the device group. The device had a chime that was set to sound three times a day when exercise sessions were scheduled. PFMT consisted of fast and slow pelvic floor muscle contraction exercises that were performed for 2 min and followed a rhythm set by the device.

RESULTS

After 8 weeks, 20 patients from the control group and 21 patients from the device group could be evaluated. In the control group, only the quality of life (QOL) index improved significantly. In the device group, however, the daily number of incontinence episodes, the number of pads used daily, the QOL index, and the pad weight in the pad test improved significantly. Patients in the device group said that they felt obligated to perform PFMT when the chime sounded. Forty-eight percent of patients from the device group were satisfied with the outcome of PFMT, while only 15% were satisfied in the control group.

CONCLUSION

This device may be useful to support the management of stress urinary incontinence.

Biofeedback and behavioral therapy for the management of female urinary incontinence

Biofeedback is useful for teaching PFM exercises, for motivation, and for compliance. The advantages of behavioral treatments are that they are safe, effective, and low risk with no documented side effects. They can be used for patients with stress, urge, or mixed urinary incontinence. Behavioral therapy has been criticized because complete cure is uncommon. However, many patients are satisfied with an improvement. Behavioral therapy is also useful as an adjunct to other therapies, such as surgery or pharmacologic treatment.
