A Dynamometer-based Wireless Pelvic Floor Muscle Force Monitoring

This paper covers the design and implementation of a proof of concept for a wireless system measuring pelvic floor muscle forces based on a dynamometer. The proposed device is the main component of a novel assessment tool intended for pelvic floor muscle rehabilitation in women suffering from urinary incontinence. The proposed system allows the physiotherapist to wirelessly monitor variation in pelvic floor muscle forces during assessment or training. Wireless communication is provided by a Bluetooth low energy transceiver and a corresponding interface designed for this purpose. Force measurements are sensed with strain gauge precision sensors operated in a Wheatstone bridge configuration. The designed module consumes 14 mW of power in operating mode. System design and experimental results are reported and discussed.

Pelvic floor muscle training: mechanisms of action for the improvement of genitourinary syndrome of menopause

Objective: This study aims to investigate the mechanism of action of pelvic floor muscle training (PFMT) for the improvement of the signs and symptoms of genitourinary syndrome of menopause (GSM) in postmenopausal women with GSM and urinary incontinence (UI).Methods: Twenty-nine women were included in the secondary analysis of a single-arm feasibility study. Using color Doppler ultrasound, the peak systolic velocity, time-averaged maximum velocity, and pulsatility index of the internal pudendal and dorsal clitoral arteries were measured at rest and after a pelvic floor muscle (PFM) contraction task. PFM function was assessed by dynamometry, and vulvovaginal tissue elasticity was measured using the Vaginal Atrophy Index.Results: PFMT significantly improved blood flow parameters in both arteries (p < 0.05) and significantly increased the speed of PFM relaxation after a contraction (p = 0.003). After the intervention, a marginally significant decrease in PFM tone was observed, as well as an increase in PFM strength (p = 0.060 and p = 0.051, respectively). Finally, improvements in skin elasticity and introitus width were observed as measured by the Vaginal Atrophy Index (p < 0.007).Conclusion: Our findings suggest that PFMT improves blood flow in vulvovaginal tissues, PFM relaxation capacity, and vulvovaginal tissue elasticity in postmenopausal women with GSM and UI.

Pelvic floor muscle training versus no treatment, or inactive control treatments, for urinary incontinence in women: a cochrane systematic review abridged republication

BACKGROUND

Pelvic floor muscle training is the most commonly used physical therapy treatment for women with urinary incontinence.

OBJECTIVES

To assess the effects of Pelvic floor muscle training for women with urinary incontinence in comparison to a control treatment and to summarize relevant economic findings.

METHODS

Cochrane Incontinence Group Specialized Register (February 12, 2018).

SELECTION CRITERIA

Randomized or quasi-randomized trials in women with stress, urgency or mixed urinary incontinence (symptoms, signs, or urodynamic).

DATA COLLECTION AND ANALYSIS

Trials were independently assessed by at least two reviewers authors and subgrouped by urinary incontinence type. Quality of evidence was assessed by adopting the Grading of Recommendations, Assessment, Development and Evaluation approach.

RESULTS

The review included thirty-one trials involving 1817 women from 14 countries. Overall, trials were small to moderate size, and many were at moderate risk of bias. There was considerable variation in the intervention's content and duration. Based on data available, we can be confident that Pelvic floor muscle training can cure or improve symptoms of stress and all other types of urinary incontinence. It may reduce the number of leakage episodes and the quantity of leakage, while improving reported symptoms and quality of life. Women were more satisfied with Pelvic floor muscle training, while those in control groups were more likely to seek further treatment. Long-term effectiveness and cost-effectiveness of Pelvic floor muscle training needs to be further researched.

CONCLUSIONS

The addition of ten new trials did not change the essential findings of the earlier review, suggesting that Pelvic floor muscle training could be included in first-line conservative management of women with urinary incontinence.

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.

Pelvic floor muscle training versus no treatment, or inactive control treatments, for urinary incontinence in women

BACKGROUND

Pelvic floor muscle training (PFMT) is the most commonly used physical therapy treatment for women with stress urinary incontinence (SUI). It is sometimes also recommended for mixed urinary incontinence (MUI) and, less commonly, urgency urinary incontinence (UUI).This is an update of a Cochrane Review first published in 2001 and last updated in 2014.

OBJECTIVES

To assess the effects of PFMT for women with urinary incontinence (UI) in comparison to no treatment, placebo or sham treatments, or other inactive control treatments; and summarise the findings of relevant economic evaluations.

SEARCH METHODS

We searched the Cochrane Incontinence Specialised Register (searched 12 February 2018), which contains trials identified from CENTRAL, MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, ClinicalTrials.gov, WHO ICTRP, handsearching of journals and conference proceedings, and the reference lists of relevant articles.

SELECTION CRITERIA

Randomised or quasi-randomised controlled trials in women with SUI, UUI or MUI (based on symptoms, signs or urodynamics). One arm of the trial included PFMT. Another arm was a no treatment, placebo, sham or other inactive control treatment arm.

DATA COLLECTION AND ANALYSIS

At least two review authors independently assessed trials for eligibility and risk of bias. We extracted and cross-checked data. A third review author resolved disagreements. We processed data as described in the Cochrane Handbook for Systematic Reviews of Interventions. We subgrouped trials by diagnosis of UI. We undertook formal meta-analysis when appropriate.

MAIN RESULTS

The review included 31 trials (10 of which were new for this update) involving 1817 women from 14 countries. Overall, trials were of small-to-moderate size, with follow-ups generally less than 12 months and many were at moderate risk of bias. There was considerable variation in the intervention's content and duration, study populations and outcome measures. There was only one study of women with MUI and only one study with UUI alone, with no data on cure, cure or improvement, or number of episodes of UI for these subgroups.Symptomatic cure of UI at the end of treatment: compared with no treatment or inactive control treatments, women with SUI who were in the PFMT groups were eight times more likely to report cure (56% versus 6%; risk ratio (RR) 8.38, 95% confidence interval (CI) 3.68 to 19.07; 4 trials, 165 women; high-quality evidence). For women with any type of UI, PFMT groups were five times more likely to report cure (35% versus 6%; RR 5.34, 95% CI 2.78 to 10.26; 3 trials, 290 women; moderate-quality evidence).Symptomatic cure or improvement of UI at the end of treatment: compared with no treatment or inactive control treatments, women with SUI who were in the PFMT groups were six times more likely to report cure or improvement (74% versus 11%; RR 6.33, 95% CI 3.88 to 10.33; 3 trials, 242 women; moderate-quality evidence). For women with any type of UI, PFMT groups were two times more likely to report cure or improvement than women in the control groups (67% versus 29%; RR 2.39, 95% CI 1.64 to 3.47; 2 trials, 166 women; moderate-quality evidence).UI-specific symptoms and quality of life (QoL) at the end of treatment: compared with no treatment or inactive control treatments, women with SUI who were in the PFMT group were more likely to report significant improvement in UI symptoms (7 trials, 376 women; moderate-quality evidence), and to report significant improvement in UI QoL (6 trials, 348 women; low-quality evidence). For any type of UI, women in the PFMT group were more likely to report significant improvement in UI symptoms (1 trial, 121 women; moderate-quality evidence) and to report significant improvement in UI QoL (4 trials, 258 women; moderate-quality evidence). Finally, for women with mixed UI treated with PFMT, there was one small trial (12 women) reporting better QoL.Leakage episodes in 24 hours at the end of treatment: PFMT reduced leakage episodes by one in women with SUI (mean difference (MD) 1.23 lower, 95% CI 1.78 lower to 0.68 lower; 7 trials, 432 women; moderate-quality evidence) and in women with all types of UI (MD 1.00 lower, 95% CI 1.37 lower to 0.64 lower; 4 trials, 349 women; moderate-quality evidence).Leakage on short clinic-based pad tests at the end of treatment: women with SUI in the PFMT groups lost significantly less urine in short (up to one hour) pad tests. The comparison showed considerable heterogeneity but the findings still favoured PFMT when using a random-effects model (MD 9.71 g lower, 95% CI 18.92 lower to 0.50 lower; 4 trials, 185 women; moderate-quality evidence). For women with all types of UI, PFMT groups also reported less urine loss on short pad tests than controls (MD 3.72 g lower, 95% CI 5.46 lower to 1.98 lower; 2 trials, 146 women; moderate-quality evidence).Women in the PFMT group were also more satisfied with treatment and their sexual outcomes were better. Adverse events were rare and, in the two trials that did report any, they were minor. The findings of the review were largely supported by the 'Summary of findings' tables, but most of the evidence was downgraded to moderate on methodological grounds. The exception was 'participant-perceived cure' in women with SUI, which was rated as high quality.

AUTHORS' CONCLUSIONS

Based on the data available, we can be confident that PFMT can cure or improve symptoms of SUI and all other types of UI. It may reduce the number of leakage episodes, the quantity of leakage on the short pad tests in the clinic and symptoms on UI-specific symptom questionnaires. The authors of the one economic evaluation identified for the Brief Economic Commentary reported that the cost-effectiveness of PFMT looks promising. The findings of the review suggest that PFMT could be included in first-line conservative management programmes for women with UI. The long-term effectiveness and cost-effectiveness of PFMT needs to be further researched.

Quality of Life in Women with Stage 1 Stress Urinary Incontinence after Application of Conservative Treatment-A Randomized Trial

Stress urinary incontinence (SUI) influences quality of life in female patients. In this study, we used ICIQ LUTS QoL (The International Consultation Incontinence Questionnaire Lower Urinary Tract Symptoms quality of life) to determine the quality of life (QoL) in various domains in patients with stage 1 SUI. The study included 140 perimenopausal women subjected to urodynamic tests at the Department of Gynaecology, Endocrinology and Gynaecologic Oncology, Pomeranian Medical University, Police (Poland) in 2013-2015. The study subjects were divided into two groups, A and B. Each patient completed two questionnaires, an original survey developed by the authors and the validated ICIQ LUTS QoL. Two exercise programs, each lasting for 3 months and consisting of 4 weekly sessions, were recommended to the study subjects. The program for Group A included exercises for pelvic floor muscles (PFM) with simultaneous tension of the transverse abdominal muscle (TrA), and the program for Group B, PFM exercises without TrA tension. After completing the exercise programs, patients with stage 1 SUI, both from Group A and from Group B, showed a significant improvement in most QoL domains measured with ICIQ LUTS QoL. However, more beneficial effects of the training were observed in the group subjected to PFM exercises with TrA tension.

BACKGROUND

Pelvic floor muscle training is the most commonly used physical therapy treatment for women with stress urinary incontinence (SUI). It is sometimes also recommended for mixed and, less commonly, urgency urinary incontinence.

OBJECTIVES

To determine the effects of pelvic floor muscle training for women with urinary incontinence in comparison to no treatment, placebo or sham treatments, or other inactive control treatments.

SEARCH METHODS

We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL) (1999 onwards), MEDLINE (1966 onwards) and MEDLINE In-Process (2001 onwards), and handsearched journals and conference proceedings (searched 15 April 2013) 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). One arm of the trial included pelvic floor muscle training (PFMT). Another arm was a no treatment, placebo, sham, or other inactive control treatment arm.

DATA COLLECTION AND ANALYSIS

Trials were independently assessed by two review authors for eligibility and methodological quality. Data were extracted then cross-checked. Disagreements were resolved by discussion. Data were processed as described in the Cochrane Handbook for Systematic Reviews of Interventions. Trials were subgrouped by diagnosis of urinary incontinence. Formal meta-analysis was undertaken when appropriate.

MAIN RESULTS

Twenty-one trials involving 1281 women (665 PFMT, 616 controls) met the inclusion criteria; 18 trials (1051 women) contributed data to the forest plots. The trials were generally small to moderate sized, and many were at moderate risk of bias, based on the trial reports. There was considerable variation in the interventions used, study populations, and outcome measures. There were no studies of women with mixed or urgency urinary incontinence alone.Women with SUI who were in the PFMT groups were 8 times more likely than the controls to report that they were cured (46/82 (56.1%) versus 5/83 (6.0%), RR 8.38, 95% CI 3.68 to 19.07) and 17 times more likely to report cure or improvement (32/58 (55%) versus 2/63 (3.2%), RR 17.33, 95% CI 4.31 to 69.64). In trials in women with any type of urinary incontinence, PFMT groups were also more likely to report cure, or more cure and improvement than the women in the control groups, although the effect size was reduced. Women with either SUI or any type of urinary incontinence were also more satisfied with the active treatment, while women in the control groups were more likely to seek further treatment. Women treated with PFMT leaked urine less often, lost smaller amounts on the short office-based pad test, and emptied their bladders less often during the day. Their sexual outcomes were also better. Two trials (one small and one moderate size) reported some evidence of the benefit persisting for up to a year after treatment. Of the few adverse effects reported, none were serious.The findings of the review were largely supported by the summary of findings tables, but most of the evidence was down-graded to moderate on methodological grounds. The exception was 'Participant perceived cure' in women with SUI, which was rated as high quality.

AUTHORS' CONCLUSIONS

The review provides support for the widespread recommendation that PFMT be included in first-line conservative management programmes for women with stress and any type of urinary incontinence. Long-term effectiveness of PFMT needs to be further researched.

Pelvic floor muscle training for stress urinary incontinence: a randomized, controlled trial comparing different conservative therapies

BACKGROUND AND PURPOSE

Pelvic floor muscle training (PFMT) is an effective therapy for stress urinary incontinence (SUI). There is little and inconsistent data about different strategies of PFMT. Finding the right, patient-oriented treatment decision seems to be essential in order to achieve good results in conservative management of SUI. It was the aim of this prospective randomized controlled trial (RCT) to compare three different strategies using electromyography (EMG) biofeedback-assisted PFMT with and without electrical stimulation (ES) for treatment of SUI in women capable of voluntarily contracting the pelvic floor when a home-training device with vaginal electrode was used.

METHOD

Three-arm RCT comparing 1) EMG biofeedback-assisted PFMT and conventional ES; 2) EMG biofeedback-assisted PFMT and dynamic ES; and 3) EMG biofeedback-assisted PFMT. Primary outcome measures were quality of life (King's Health Questionnaire) and degree of suffering (rated on a visual analogue scale from 1 to 10). Secondary outcome measures were number of pads used, pad weight test, contractility of the pelvic floor measured by digital palpation and intra-vaginal EMG.

RESULTS

The quality of life significantly increased over the 12-week training. The number of pads used was reduced, the pad weight test and the contractility of the pelvic floor significantly improved. There were no significant differences between the three groups.

CONCLUSION

This RCT shows significant improvement in patients' quality of life for conservative therapy of SUI. Differences between the three therapeutic options analyzed could not be found. Additional ES showed no benefit for patients with SUI, capable of voluntary pelvic floor contraction.

Pelvic floor muscle training versus no treatment, or inactive control treatments, for urinary incontinence in women

BACKGROUND

Pelvic floor muscle training is the most commonly used physical therapy treatment for women with stress urinary incontinence. It is sometimes recommended for mixed and less commonly urge urinary incontinence.

OBJECTIVES

To determine the effects of pelvic floor muscle training for women with urinary incontinence in comparison to no treatment, placebo or sham treatments, or other inactive control treatments.

SEARCH STRATEGY

The Cochrane Incontinence Group Specialised Trials Register (searched 18 February 2009) and the reference lists of relevant articles were searched.

SELECTION CRITERIA

Randomised or quasi-randomised trials in women with stress, urge or mixed urinary incontinence (based on symptoms, signs, or urodynamics). One arm of the trial included pelvic floor muscle training (PFMT). Another arm was a no treatment, placebo, sham, or other inactive control treatment arm.

DATA COLLECTION AND ANALYSIS

Trials were independently assessed for eligibility and methodological quality. Data were extracted then cross-checked. Disagreements were resolved by discussion. Data were processed as described in the Cochrane Handbook (Higgins 2008). Trials were subgrouped by diagnosis. Formal meta-analysis was not undertaken because of study heterogeneity.

MAIN RESULTS

Fourteen trials involving 836 women (435 PFMT, 401 controls) met the inclusion criteria; twelve trials (672) contributed data to the analysis. Many studies were at moderate to high risk of bias, based on the trial reports. There was considerable variation in interventions used, study populations, and outcome measures.Women who did PFMT were more likely to report they were cured or improved than women who did not. Women who did PFMT also reported better continence specific quality of life than women who did not. PFMT women also experienced fewer incontinence episodes per day and less leakage on short office-based pad test. Of the few adverse effects reported, none were serious. The trials in stress urinary incontinent women which suggested greater benefit recommended a longer training period than the one trial in women with detrusor overactivity (urge) incontinence.

AUTHORS' CONCLUSIONS

The review provides support for the widespread recommendation that PFMT be included in first-line conservative management programmes for women with stress, urge, or mixed, urinary incontinence. Statistical heterogeneity reflecting variation in incontinence type, training, and outcome measurement made interpretation difficult. The treatment effect seems greater in women with stress urinary incontinence alone, who participate in a supervised PFMT programme for at least three months, but these and other uncertainties require testing in further trials.

WITHDRAWN: Pelvic floor muscle training for urinary incontinence in women

BACKGROUND

Pelvic floor muscle training is the most commonly recommended physical therapy treatment for women with stress leakage of urine. It is also used in the treatment of women with mixed incontinence, and less commonly for urge incontinence. Adjuncts, such as biofeedback or electrical stimulation, are also commonly used with pelvic floor muscle training. The content of pelvic floor muscle training programmes is highly variable.

OBJECTIVES

To determine the effects of pelvic floor muscle training for women with symptoms or urodynamic diagnoses of stress, urge and mixed incontinence, in comparison to no treatment or other treatment options.

SEARCH STRATEGY

Search strategy: We searched the Cochrane Incontinence Group trials register (May 2000), Medline (1980 to 1998), Embase (1980 to 1998), the database of the Dutch National Institute of Allied Health Professions (to 1998), the database of the Cochrane Rehabilitation and Related Therapies Field (to 1998), Physiotherapy Index (to 1998) and the reference lists of relevant articles. We handsearched the proceedings of the International Continence Society (1980 to 2000). We contacted investigators in the field to locate studies. Date of the most recent searches: May 2000.

SELECTION CRITERIA

Randomised trials in women with symptoms or urodynamic diagnoses of stress, urge or mixed incontinence that included pelvic floor muscle training in at least one arm of the trial.

DATA COLLECTION AND ANALYSIS

Two reviewers assessed all trials for inclusion/exclusion and methodological quality. Data were extracted by the lead reviewer onto a standard form and cross checked by another. Disagreements were resolved by discussion. Data were processed as described in the Cochrane Handbook. Sensitivity analysis on the basis of diagnosis was planned and undertaken where appropriate.

MAIN RESULTS

Forty-three trials met the inclusion criteria. The primary or only reference for 15 of these was a conference abstract. The pelvic floor muscle training programs, and comparison interventions, varied markedly. Outcome measures differed between trials, and methods of data reporting varied, making the data difficult to combine. Many of the trials were small. Allocation concealment was adequate in five trials, and nine trials used assessors masked to group allocation. Thirteen trials reported that there were no losses to follow up, seven trials had dropout rates of less than 10%, but in the remaining trials the proportion of dropouts ranged from 12% to 41%. Pelvic floor muscle training was better than no treatment or placebo treatments for women with stress or mixed incontinence. 'Intensive' appeared to be better than 'standard' pelvic floor muscle training. PFMT may be more effective than some types of electrical stimulation but there were problems in combining the data from these trials. There is insufficient evidence to determine if pelvic floor muscle training is better or worse than other treatments. The effect of adding pelvic floor muscle training to other treatments (e.g. electrical stimulation, behavioural training) is not clear due to the limited amount of evidence available. Evidence of the effect of adding other adjunctive treatments to PFMT (e.g. vaginal cones, intravaginal resistance) is equally limited. The effectiveness of biofeedback assisted PFMT is not clear, but on the basis of the evidence available there did not appear to be any benefit over PFMT alone at post treatment assessment.Long-term outcomes of pelvic floor muscle training are unclear. Side effects of pelvic floor muscle training were uncommon and reversible. A number of the formal comparisons should be viewed with caution due to statistical heterogeneity, lack of statistical independence, and the possibility of spurious confidence intervals in some instances.

AUTHORS' CONCLUSIONS

Pelvic floor muscle training appeared to be an effective treatment for adult women with stress or mixed incontinence. Pelvic floor muscle training was better than no treatment or placebo treatments. The limitations of the evidence available mean that is difficult to judge if pelvic floor muscle training was better or worse than other treatments. Most trials to date have studied the effect of treatment in younger, premenopausal women. The role of pelvic floor muscle training for women with urge incontinence alone remains unclear. Many of the trials were small with poor reporting of allocation concealment and masking of outcome assessors. In addition there was a lack of consistency in the choice and reporting of outcome measures that made data difficult to combine. Methodological problems limit the confidence that can be placed in the findings of the review. Further, large, high quality trials are necessary.

Meta-Analysis of Pelvic Floor Muscle Training

BACKGROUND

Although many studies have reported the effectiveness of pelvic floor muscle training (PFMT) for treating female urinary incontinence, the magnitude of the effect and the optimal configuration of the parameters of the training have not been clearly determined.

OBJECTIVES

The aims of this meta-analysis were: (a) to calculate the effect size of pelvic floor muscle training compared to no treatment on incontinent episodes, urine leakage amount, and perceived severity of urine loss, and (b) to identify parameters of PFMT and subjects' characteristics influencing the magnitude of the effects.

METHODS

The search for relevant literature published from 1980 to 2005 consisted of using several computerized databases, citation searching, and footnote chasing. Twelve studies met the inclusion criteria, and were reviewed and coded.

RESULTS

The overall mean weighted effect size on incontinent episodes, urine leakage amount, and perceived severity were -0.68 (Z = 5.89, p < .001), -1.48 (Z = 2.64, p = .008), and -1.66 (Z = 1.68, p = .092), respectively. The studies with women having stress urinary incontinence showed a mean weighted effect size of -0.77 (Z = 7.03, p < .001), whereas studies with women having any type of urinary incontinence showed a mean weighted effect size of -0.47 (Z = 4.40, p < .001). The mean weighted effect size for studies including subjects over 60 years mean age was -0.54 (Z = 6.21, p < .001), whereas that of studies in which the average age was younger than 60 years was -0.94 (Z = 6.58, p < .001).

DISCUSSION

The treatment effect of PFMT on the incontinent episodes may be greater in younger women with only stress urinary incontinence. It appears that the number of daily contractions and the length of training period are not related to effect sizes on the condition that training includes at least daily 24 contractions and keeps for at least 6 weeks.

Rehabilitation Therapy and Urinary Incontinence after Radical Retropubic Prostatectomy

INTRODUCTION

To assess the efficacy and evidence-based data in the literature about rehabilitation therapy in patients with post-prostatectomy urinary incontinence.

MATERIALS AND METHODS

An analysis of published full-length papers identified by a Medline search from 1990 through 2004 was carried out. Abstracts published in peer-reviewed journals in the same period of time were also considered.

RESULTS

Efficacy, tolerability and safety of rehabilitation therapy were evaluated, according to the available data in the literature, with special regard to randomized controlled trials in order to define a clear-cut, evidence-based efficacy of this form of therapy.

CONCLUSIONS

Rehabilitation therapy is a simple and safe way of managing post-prostatectomy urinary incontinence. Nonetheless, few randomized controlled studies have been carried out so far to establish its evidence-based efficacy and it is thus not possible to be scientifically sure of its value. It is therefore necessary to undertake well-designed randomized controlled studies, with a large number of patients, a well-matched control group and an adequate follow-up.

Pelvic floor muscle training versus no treatment, or inactive control treatments, for urinary incontinence in women

BACKGROUND

Pelvic floor muscle training is the most commonly used physical therapy treatment for women with stress urinary incontinence. It is sometimes recommended for mixed and less commonly urge urinary incontinence.

OBJECTIVES

To determine the effects of pelvic floor muscle training for women with urinary incontinence in comparison to no treatment, placebo or sham treatments, or other inactive control treatments.

SEARCH STRATEGY

The Cochrane Incontinence Group Specialised Trials Register was searched. The date of the most recent search was 1 December 2004.

SELECTION CRITERIA

Randomised or quasi-randomised trials in women with stress, urge or mixed urinary incontinence (based on symptoms, signs, or urodynamics). One arm of the trial included pelvic floor muscle training (PFMT). Another arm was a no treatment, placebo, sham, or other inactive control treatment arm.

DATA COLLECTION AND ANALYSIS

Trials were independently assessed for eligibility and methodological quality. Data were extracted then cross-checked. Disagreements were resolved by discussion. Data were processed as described in the Cochrane Handbook (Higgins 2005). Trials were subgrouped by diagnosis. Formal meta-analysis was not undertaken because of study heterogeneity.

MAIN RESULTS

Thirteen trials involving 714 women (375 PFMT, 339 controls) met the inclusion criteria, but only six trials (403 women) contributed data to the analysis. Most studies were at moderate to high risk of bias, based on the trial reports. There was considerable variation in interventions used, study populations, and outcome measures. Women who did PFMT were more likely to report they were cured or improved than women who did not. PFMT women also experienced about one fewer incontinence episodes per day. There were too few data to draw conclusions about effects on other outcomes such as condition specific quality of life. Of the few adverse effects reported, none were serious. The trials in stress urinary incontinent women which suggested greater benefit recruited a younger population and recommended a longer training period than the one trial in women with detrusor overactivity (urge) incontinence.

AUTHORS' CONCLUSIONS

Overall, the review provides some support for the widespread recommendation that PFMT be included in first-line conservative management programmes for women with stress, urge, or mixed, urinary incontinence. Statistical heterogeneity reflecting variation in incontinence type, training, and outcome measurement made interpretation difficult. The treatment effect might be greater in younger women (in their 40's and 50's) with stress urinary incontinence alone, who participate in a supervised PFMT programme for at least three months, but these and other uncertainties require testing in further trials.

El papel del fisioterapeuta pélvico

Pelvic physical therapy focuses on the prevention and the treatment of all kinds of functional disorders of the abdominal, pelvic and low back region, like urinary incontinence, that is considered as a high prevalent health problem in women, men, children and the elderly. Physical therapy is often considered as the first-choice treatment, due to its non-invasive character, the results in terms of symptom relief, the possibility of combining physical therapy with other treatments, the low risk of side effects and the moderate to low costs. Important restrictions for success might be motivation and perseverance of patient and therapist and the time needed for physical therapy. The armentum of the pelvic physical therapist contains interventions such as physiotherapeutic diagnostics, education and information of patients, pelvic floor muscle (PFM) training, bladder training (BlT), training with vaginal cones, electrical stimulation, biofeedback, etc. In stress incontinence, to improve the extrinsic closing mechanism of the urethra, physical therapy is aimed on strength improvement and coordination of the peri-urethral and pelvic floor muscles. Especially, PFM training is effective. For detrusor overactivity physical therapy aims to reduce or eliminate involuntary detrusor contractions through reflexinhibition. Here, electrical therapy appears to be an effective intervention. In mixed urinary incontinence the physiotherapeutic diagnostic and therapeutic process focuses on the predominant factors. Radical prostatectomy is the most important cause of incontinence in men. An adequate program of PFM training, after radical prostatectomy, decreases the duration and the extent of incontinence and improves the quality of life.

CONCLUSION

physical therapy is in many cases of incontinence an effective treatment option.

Behavioral Therapies at the Primary Care Level

Urinary incontinence, the complaint of any involuntary loss of urine, is a troubling symptom experienced by men and women of all ages. Options for treatment include a range of behavioral, pharmacologic, and surgical therapies. Behavioral therapies, such as dietary modification, pelvic floor muscle training, and bladder training, are noninvasive, with little risk of side effects, and experts agree they should represent the first line of treatment whenever possible. These therapies can be initiated and monitored at the primary care level, thereby enhancing the accessibility of care for those affected. The purpose of this article is to methodically review what is and is not known about behavioral therapies, with attention to research needs. Although there is clear evidence for pelvic floor muscle training in women with urinary incontinence and modest evidence in men for a short time after radical prostatectomy, less is known about bladder training, prompted voiding, habit retraining, and timed voiding. Additional research is required to enhance our understanding of the comparative efficacy of behavioral interventions in specific populations. This research must take an increasingly long-term focus, given the potentially chronic nature of urinary incontinence.

An anatomical description of the male and female urethral sphincter complex

PURPOSE

We performed a detailed study of the lower urinary tract of the male and female human fetus to elucidate the anatomy of the urethral sphincter complex in both sexes and its relationship to the surrounding organs and tissues.

MATERIALS AND METHODS

A total of 12 male and 14 female normal human pelvic specimens ranging from 17.5 to 38 weeks of gestation were studied by serial sections and immunohistochemical analysis. Three-dimensional reconstructions were created from serial sections to demonstrate the anatomy of the lower urogenital tract and urethral sphincter in both sexes. Specific attention was directed to the sphincteric muscle of the urethra.

RESULTS

The urinary continence mechanism is formed by a combination of detrusor, trigone and urethral sphincter muscles with distinctive histological characteristics in both sexes. In males the external urethral sphincter covers the ventral surface of the prostate as a crescent shape above the verumontanum, horseshoe shape below the verumontanum and crescent shape along the proximal bulbar urethra. The levator ani muscles form an open circle around the external sphincter with a hiatus at the ventral aspect. In females the external urethral sphincter covers the ventral surface of the urethra in a horseshoe shape. Caudally the same horseshoe-shaped external sphincter increases in size to envelop the distal vagina. The levator ani muscles do not support the proximal urethra. The smooth and striated muscle components of the urethral sphincter complex are inseparable in both sexes.

CONCLUSIONS

The developmental anatomy of the urethral sphincter complex is analogous in both sexes. The male and female urinary sphincter mechanism is composed of detrusor, trigone and urethral muscles, each of different muscular origins. The levator ani does not surround the ventral aspect of the urethra and may not have an active role in continence in both sexes. This new concept in the anatomy of male and female sphincter morphology may help to refine our reconstructive and ablative surgical techniques.

Reliability of dynamometric measurements of the pelvic floor musculature

AIMS

The objective of this study was to evaluate the reliability of strength and endurance dynamometric measurements of the pelvic floor musculature (PFM).

MATERIALS AND METHODS

Twenty-nine female participants, primipara and multipara, aged between 27 and 42 and presenting different severity levels of stress urinary incontinence (SUI), participated in the study. They were evaluated using a new pelvic floor dynamometer, an instrumented speculum based on strain-gauged technology. Strength and endurance evaluations were repeated in three successive sessions, each followed by a 4-week period. Maximal strength values were recorded at three dynamometer openings (5 mm, 1 cm, and 1.5 cm between the two dynamometer branches). The maximal rate of force development (MRFD) and percentage of strength lost after 10 and 60 sec were computed from the endurance trial. The generalizability theory was applied to estimate the reliability of the PFM measurements. The reliability was quantified by the index of dependability and the corresponding standard error of measurement (SEM) for one and the mean of three trials performed in one session for the strength measurements and one trial completed in one session for the MRFD and endurance measurements.

RESULTS

For the maximal strength measurements, the largest coefficient of dependability was obtained at the 1 cm opening, with a value of 0.88. The corresponding SEM reached 1.49 N. The reliability of the MRFD was also very good with a coefficient of 0.86 and an SEM of 0.056 N/sec. The reliability was minimally affected by the number of trials. The strength loss measurements at 10 and 60 sec were unreliable, with coefficient values of 0.38 and 0.10, respectively.

CONCLUSIONS

The results of the present study indicate that the reliability of the strength parameters (maximal strength and MRTD measurements) was high enough for future investigations on pelvic floor rehabilitation programs.

Development of a dynamometer for measuring the isometric force of the pelvic floor musculature

AIMS

The aim of this study was to design and develop a dynamometer providing a direct measurement of pelvic floor muscle (PFM) strength.

MATERIALS AND METHODS

Two pairs of strain gauges were mounted on the moveable branch of a dynamometric speculum allowing measurements at different vaginal apertures. Linearity, repeatability, independence of the site of application of the resultant force to the lower branch of the speculum and hysteresis were tested by means of in vitro calibration studies.

RESULTS

The linearity proved excellent over a range of 0-15 N with regression coefficients close to unity between imposed loads and voltage outputs. The slopes and intercepts of the regression lines were not significantly different between repeated sessions, indicating the high reliability of these in vitro measurements. The slopes and intercepts of the calibrations, using the same repertoire of loads imposed at three locations on the moving branch of the dynamometer, were not significantly different, confirming that the force measurement is independent of the site of the force application. Hysteresis was considered to be minimal.

CONCLUSIONS

This study demonstrates that the dynamometer provides reliable measurements. The new device thus appears to have conceptual and measuring advantages over conventional methods and seems to be a very promising instrument for measuring pelvic floor strength.

Transabdominal ultrasound measurement of pelvic floor muscle activity when activated directly or via a transversus abdominis muscle contraction

AIMS

The purpose of the present study was to compare the effectiveness of instruction to contract the pelvic floor muscles (PFM), the transversus abdominis (TrA), and the TrA + PFM visualized as displacement of the pelvic floor by ultrasound.

MATERIALS AND METHODS

Twenty female physical therapists, mean age 41.1 years (range 26-56) participated in the study. A 3.5 MHz 35 mm curved linear array ultrasound transducer (Dornier Medtech) was placed in the mid-sagittal plane immediately suprapubically, angled at 15-30 degrees from the vertical depending on subcutaneous fat and anatomical variations, to image the pelvic floor. Six trials of three maneuvers in random order were performed: contraction of PFM, TrA, and TrA + PFM.

RESULTS

In spite of correct contractions assessed by palpation and clinical observation, one subject demonstrated a downward movement of the pelvic floor during PFM contraction on ultrasound. Six subjects (30%) showed a downward movement during a TrA- contraction, and two during the combined TrA + PFM contraction. Instruction to contract PFM produced significantly greater mean displacement: 11.2 mm (95% CI 7.2-15.3) than TrA 4.3 mm (95% CI -0.2-8.8), P < 0.01, and combination: 8.5 mm (95% CI 5.2-12), P = 0.04. Hence, instruction of PFM contraction produced a 61.6% greater displacement of the pelvic floor in the correct direction than a TrA contraction.

CONCLUSIONS

It is concluded that ultrasound is a more valid method than palpation and clinical observation to assess PFM function, and that instruction to contract the PFM produces a significantly more effective pelvic floor muscle contraction than instruction to perform a TrA contraction.

Videourodynamic analysis of the relationship of Valsalva and cough leak point pressures in women with stress urinary incontinence

OBJECTIVES

To use videourodynamic assessment to investigate the relationship between Valsalva leak point pressure (VLPP) and cough leak point pressure (CLPP) in women with stress urinary incontinence (SUI).

METHODS

A total of 116 women with SUI were retrospectively analyzed by videourodynamic results, urethral pressure profilometry, and leak point pressure findings. All women had urine leakage during both coughing and performance of the Valsalva maneuver. The grade of SUI, VLPP, CLPP, maximal urethral closure pressure, and bladder neck descent during the stress test were compared among patients categorized according to three VLPP groups of less than 60 cm H(2)O, 60 or greater but less than 90 cm H(2)O, and 90 cm H(2)O or greater.

RESULTS

A significant inverse correlation was found between the grade of SUI and VLPP (r = -0.620, P = 0.000) and CLPP (r = -0.506, P = 0.000). The VLPP was less than 60 cm H(2)O in 41 women, 60 or greater but less than 90 cm H(2)O in 36, and 90 cm H(2)O or greater in 39. The CLPP was greater than the VLPP in 101 women (87.1%) and equaled the VLPP in 15 women (12.9%). Of the 41 women with a VLPP less than 60 cm H(2)O, 38 (92.6%) had a CLPP greater than the VLPP and 16 (39%) had greater bladder neck descent. The maximal urethral closure pressure had a weak but significant correlation with the VLPP (r = 0.299, P = 0.011) and CLPP (r = 0.325, P = 0.005).

CONCLUSIONS

The results of this study have demonstrated that the Valsalva maneuver and cough caused urinary leakage by different activities. A lower leak point pressure was found with VLPP than with CLPP to diagnose intrinsic sphincter deficiency. Complete assessment of urethral function, VLPP, CLPP, and bladder neck descent is essential for diagnosis and treatment of SUI.

Conservative therapy for overactive bladder: pelvic floor exercises

Overactive bladder affects the lives of millions of people. Anticholinergic medications are traditionally used to treat this condition, but some patients find these agents difficult to tolerate and ineffective. Conservative treatment with pelvic floor exercises, with or without biofeedback, electric stimulation, and behavioral modification, are excellent modalities that can be effective in the motivated patient. This review describes the available literature supporting the efficacy of pelvic floor exercises in the treatment of overactive bladder and guidelines for patient selection.

Dynamic MRI of the pelvic floor muscles in an upright sitting position

Since the pelvic floor muscles are situated inside the pelvis, the actual function is difficult to observe. Magnetic resonance imaging (MRI) is a new method that may prove to give additional information about pelvic floor muscle function during contraction. The purpose of the present study was to assess pelvic floor muscle function during contraction and straining in an upright sitting position by use of MRI. Sixteen women, nine continent and seven with urodynamically and clinically proven genuine stress incontinence participated in the study. MRI was performed in an open-configured GE Signa SP, 0.5 T Tesla magnet. With the participants sitting in an upright position on a pelvic RF-coil, sagittal, coronal and axial T1 weighted spin echo images of the pelvic floor were obtained. During contraction and straining a scan time of 2 seconds per image for 150-250 images, was performed in a mid-sagittal plane. The results showed that the mean inward lift during contraction was 10.8 mm (SD 6.0) for all women. During straining the mean downward movement was 19.1 mm (SD 7.4). The coccyx moved in a ventral, cranial direction during contraction and was pressed in a caudal, dorsal direction during straining. It is concluded that contraction of the pelvic floor muscles is concentric, moving the coccyx in a ventral, cranial direction. The movement measured by MRI in upright sitting position is less than that concluded after clinical observation in supine position. The coccyx is pressed dorsally during straining.
