Pelvic Floor Physical Therapy for Pelvic Floor Hypertonicity: A Systematic Review of Treatment Efficacy.

INTRODUCTION: Hypertonicity of the pelvic floor (PFH) is a disabling condition with urological, gynecological and gastrointestinal symptoms, sexual problems and chronic pelvic pain, impacting quality of life. Pelvic floor physical therapy (PFPT) is a first-line intervention, yet no systematic review on the efficacy of PFPT for the treatment of PFH has been conducted. OBJECTIVES: To systematically appraise the current literature on efficacy of PFPT modalities related to PFH. METHODS: PubMed, Embase, Emcare, Web of Science, and Cochrane databases were searched from inception until February 2020. A manual search from reference lists of included articles was performed. Ongoing trials were reviewed using clinicaltrial.gov. Randomized controlled trials (RCTs), prospective - and retrospective cohorts and case-study analyses were included. Outcome measures were pelvic floor muscle tone and function, pain reports, sexual function, pelvic floor symptom scores, quality of life and patients' perceived effect. RESULTS: The literature search resulted in 10 eligible studies including 4 RCTs, 5 prospective studies, and 1 case study published between 2000 and 2019. Most studies had a high risk of bias associated with the lack of a comparison group, insufficient sample sizes and non-standardized interventions. Six studies were of low and 4 of medium quality. All studies were narratively reviewed. Three of 4 RCTs found positive effects of PFPT compared to controls on five out of 6 outcome measures. The prospective studies found significant improvements in all outcome measures that were assessed. PFPT seems to be efficacious in patients with chronic prostatitis, chronic pelvic pain syndrome, vulvodynia, and dyspareunia. Smallest effects were seen in patients with interstitial cystitis and painful bladder syndrome. CONCLUSION: The findings of this systematic review suggest that PFPT can be beneficial in patients with PFH. Further high-quality RCTs should be performed to confirm the effectiveness of PFPT in the treatment of PFH. van Reijn-Baggen DA, Han-Geurts IJM, Voorham-van der Zalm PJ, et al.

The effect of EMG biofeedback assisted pelvic floor muscle therapy on symptoms of the overactive bladder syndrome in women: A randomized controlled trial.

AIMS: The overactive bladder syndrome (OAB) is defined as urinary urgency, usually accompanied by frequency and nocturia, with or without urgency urinary incontinence. Biofeedback-assisted pelvic muscle therapy (BAPFMT) is a first-line treatment option for OAB. The aims of this study were to determine the efficacy and effectiveness of BAPFMT on symptoms of OAB after 9 weeks of treatment and to detect changes EMG activity of individual pelvic floor muscles (PFM) with the MAPLe. METHODS: Patients were randomly divided into an intervention group that received BAPFMT with the MAPLe or into a control group which received only toilet behavior and lifestyle instructions. The Pelvic Floor Inventories (PeLFIs), the King's Health Questionnaire (KHQ), a voiding dairy, a 24 h pad-test, and vaginal EMG registration of the pelvic floor with the MAPLe were used at inclusion and after 9 weeks follow-up to determine the effect of BAPFMT on complaints of OAB and Quality of Life (QoL). RESULTS: Fifty-eight patients were included. The PeLFIs, KHQ, voiding dairy, and 24 h pad-test showed significant improvements in the intervention group compared to the control group in complaints of OAB and QoL. EMG activity showed significant improvements for specific individual muscles at the different sides and depths for rest, maximal voluntary contraction, and endurance. CONCLUSIONS: EMG BAPFMT is effective in the OAB syndrome in women. It significantly reduces symptoms and complaints of OAB and increases QoL for patients. It shows that EMG changes in individual PFM, measured with the MAPLe, are relevant and related to symptom reduction.

Effect of preoperative pelvic floor muscle therapy with biofeedback versus standard care on stress urinary incontinence and quality of life in men undergoing laparoscopic radical prostatectomy: a randomised control trial.

AIMS: Laparoscopic radical prostatectomy (LARP) may cause stress urinary incontinence (SUI). This study reports the effects of preoperative pelvic floor muscle therapy (PFMT) on SUI and quality of life (QoL) in men undergoing LARP. MATERIALS AND METHODS: In this single-center randomized controlled trial, 122 patients undergoing LARP were assigned to an intervention group of PFMT with biofeedback once a week preoperatively, with 4 weeks' follow-up or to a control group receiving standard care. Randomization and allocation to the trial group were carried out by a central computer system. The primary analysis was based on 121 (n = 65; n = 56), comparing SUI rates and QoL in the two groups in a 1-year follow-up. Validated questionnaires, the Pelvic Floor Inventories (PeLFls), the King's Health Questionnaire (KHQ), the International Prostate Symptom Score (IPSS), a bladder diary, a 24-hr pad test and pelvic floor examination were used. Continence was defined as no leakage at all. All analyses were performed according to intention-to-treat. RESULTS: One hundred twenty-two patients were randomized, 19 patients were excluded from analysis because of early drop-out. There were no significant differences between both groups in the incidence of SUI and QoL based on the KHQ, IPSS, and pad tests (P ≥ 0.05). In all patients continence was achieved in 77.2% at 1 year postoperatively. CONCLUSIONS: Preoperative PFMT does not appear to be effective in the prevention of SUI and QoL following LARP.

Reliability and differentiation of pelvic floor muscle electromyography measurements in healthy volunteers using a new device: the Multiple Array Probe Leiden (MAPLe).

AIMS: A new multiple electrode probe, the Multiple Array Probe Leiden (MAPLe), has been developed for biofeedback registration of the individual pelvic floor musculature (PFM). The aim was to determine the reliability and differentiation of electromyography (EMG) signals measured with the MAPLe in healthy volunteers. METHODS: Two hundred twenty nine healthy volunteers not seeking treatment or using medication for symptoms of prolapse, lower urinary tract, bowel, pain, and/or sexual function related to pelvic floor dysfunction were qualified to participate. Subjects were asked to perform five tasks: rest, maximum voluntary contractions, endurance, cough, and valsalva. Mean EMG values per electrode were registered. Test-retest reliability was assessed using linear mixed model with random subject effects. One-way ANOVA tests were performed to detect differences between groups. RESULTS: Magnetic resonance imaging (MRI) showed that each of the electrodes could be related nearest to the individual muscles. For test-retest, the intraclass correlation ranged from 0.53 to 0.91. The MAPLe showed significant differences in average EMG values between men and women, and between nulliparous and parous, pre- and prostmenpausal women. Significant differences were seen between the left and right sides of the pelvic floor. In addition, the activity nearest to the individual pelvic floor muscles (external anal sphincter (EAS), puborectalis muscle, bulbospongiosus, ischiocavernosus and the pubococcygeus muscle) could be determined. CONCLUSIONS: The MAPLe is a reliable instrument measuring the EMG signals of the different sides and levels nearest to the pelvic floor musculature and is capable to differentiate between men and women, nulliparous, parous, pre- and postmenopausal. The findings of this study have implications for the diagnosis and treatment of pelvic floor dysfunction in the future.

Validation of the Pelvic Floor Inventories Leiden (PelFIs) in English.

AIMS: To evaluate the validity and reliability of the English translation of an interviewer-administered pelvic floor questionnaire, the "Pelvic Floor Inventories Leiden" (PeLFIs) for women, which addresses complaints of prolapse, bladder, and bowel dysfunction, pelvic floor pain and/or sexual dysfunction related to pelvic floor dysfunction. METHODS: The formal forward-backward translation of the PeLFIs was performed by bilingual Dutch/English translators. The final English version was administered to healthy volunteers (N = 94) and patients (N = 180) in Canada and the United States. Psychometric properties of the English version were examined, including internal consistency, test-retest reliability, content, and construct validity. Internal consistency was measured using Cronbach's alpha. Test-retest reliability was assessed by intraclass correlation coefficients. Construct validity was established by comparing scores in healthy volunteers and patients (using t-tests) and by intercorrelating domains. RESULTS: The forward-backward translation of the English version of the PeLFIs was consistent with the original Dutch questionnaire. In total, 274 questionnaires were administered. The retest was administered 2 weeks after the initial PeLFIs interview. Internal consistency of the questionnaire was 0.88 for the total scale. Cronbach's alpha of the domains ranged from 0.71 to 0.95. For the test-retest reliability, the agreement rate between the two tests exceeded 95% and the intraclass correlation ranged from 0.6 to 0.8. The differences between healthy volunteers and patients were statistically significant for all domains, but did not exceed the minimal important difference for some domains. Correlations between the domains were moderate to high. CONCLUSIONS: The PeLFIs questionnaire has been translated successfully into English and in its evaluation has shown adequate internal consistency and reliability.

Pelvic floor dysfunction is not a risk factor for febrile urinary tract infection in adults.

OBJECTIVE: To determine whether pelvic floor dysfunction (PFD) might be a risk factor for or consequence of febrile urinary tract infection (UTI), as UTI in adults is a common infection in which an underlying urological abnormality is often considered, and as in children, PFD is also thought to have a pathophysiological role in adults with UTI. PATIENTS AND METHODS: A multicentre case-control study was conducted at 26 primary-care centres and at six Emergency Departments of regional hospitals. Cases were consecutive patients aged > or =18 years, who presented with febrile UTI. Controls were randomly selected subjects who visited their general practitioner for reasons other than UTI or fever. A validated pelvic floor questionnaire (the Pelvic Floor Inventories Leiden, PelFIs) was used to assess pelvic floor function. RESULTS: Between October 2006 and December 2007, 153 cases were included; of these, the completed questionnaires of 102 (response rate 67%) were compared to those of 100 of 110 (response rate 91%) controls. The median age of cases and controls was 65 and 58 years, respectively; 40% of cases and controls were men. The percentage of PelFIs outcomes consistent with PFD were comparable between cases and controls, at 21% vs 23%, respectively (odds ratio 0.9, 95% confidence interval, CI, 0.4-1.78). In the multivariate analysis, comorbidity (odds ratio 4.9, 95% CI 2.2-11.1) and a history of UTI (odds ratio 2.5, 95% CI 1.0-6.1) were independent significant risk factors for febrile UTI, whereas PFD was not (odds ratio 1.0, 0.5-2.2). Within the group of cases, PFD was not associated with bacteriuria during assessment of PelFIs (odds ratio 1.1, 95% CI 0.4-3.5) and inversely related to a history of UTI within the previous year (odds ratio 0.2, 0.1-0.9). CONCLUSIONS: PFD is common among adults but it does not seem to be a risk factor for febrile UTI.

Chronic testicular pain as a symptom of pelvic floor dysfunction.

PURPOSE: We determined whether chronic testicular pain is related to pelvic floor overactivity after ruling out other disease pathology. MATERIALS AND METHODS: A total of 41 patients with chronic testicular pain evaluated at our Pelvic Floor Department at a tertiary academic center were included in this retrospective study. All patients underwent standard pelvic floor investigation, including history using a standardized questionnaire and electromyography registration of the pelvic floor. In the questionnaire patients were asked about complaints in 3 domains (micturition, defecation and sexual function) suggestive of pelvic floor dysfunction. Electromyography registration of the pelvic floor was performed. The resting tone of the pelvic floor was considered increased at 3 muV or greater. RESULTS: Mean patient age was 48 years. Of the patients 93% had at least 1 symptom suspicious of pelvic floor dysfunction. A total of 22% had complaints in 1 of the domains of micturition, defecation or sexual function, 24% had complaints in 2 domains and 49% had complaints in all 3 domains. On electromyography registration of the pelvic floor 88% of patients appeared to have an increased resting tone of the pelvic floor muscles at a mean of 6.7 muV (normal less than 3). The patients with a normal pelvic floor resting tone were significantly older than those with an increased resting tone (65.6 vs 45.6, p = 0.0001). CONCLUSIONS: Chronic testicular pain can be a symptom of pelvic floor overactivity, especially in younger patients. A diagnostic evaluation should be performed when no pathophysiology can be found.

Multiple pelvic floor complaints are correlated with sexual abuse history.

INTRODUCTION: The relationship between sexual abuse and urinary tract symptoms, sexual abuse and gastrointestinal symptoms, or sexual abuse and sexual dysfunction has been described before. A correlation between all these symptoms and sexual abuse has not yet been reported. AIMS: The first aim of this study was to document the prevalence rates of reported sexual abuse in a large sample of female patients with complaints of the pelvic floor. The second aim was to evaluate the frequency of complaints in the different domains of the pelvic floor, such as complaints of micturition, defecation, and sexual function, in female patients reporting sexual abuse, and comparing these data with female patients without a history of sexual abuse. METHODS: Female patients with pelvic floor complaints were evaluated in a tertiary referral center. History taking was assessed by a pelvic-floor clinician. The number of domains with complaints of patients with a history of sexual abuse was compared with the number of domains with complaints of patients without sexual abuse. MAIN OUTCOME MEASURES: The number of patients who reported sexual abuse and the frequency of complaints in the different domains of the pelvic floor. The number of domains of patients with a history of sexual abuse was compared with patients without a history of sexual abuse. RESULTS: Twenty-three percent (42/185) of the patients reported a history of sexual abuse. The female patients with a history of sexual abuse had significantly more complaints in three domains of the pelvic floor (35/42) compared with the nonabused (69/143) (83% vs. 48%, P < 0.001). CONCLUSIONS: Twenty-three percent of the female patients in a pelvic floor center evaluated by a pelvic-floor clinician reported a history of sexual abuse. This is comparable with the percentage of sexual abuse observed in the population at large. In our sample, the patients with multiple pelvic floor complaints (micturition, defecation, and sexual function) related to pelvic floor dysfunction were more likely to have a history of sexual abuse than the patients with isolated complaints.

"Diagnostic investigation of the pelvic floor": a helpful tool in the approach in patients with complaints of micturition, defecation, and/or sexual dysfunction.

INTRODUCTION: Pelvic floor dysfunction is recognized to be related to lower urinary tract dysfunction and to lower gastrointestinal symptoms, and is an influential factor in dysfunction and subsequent behavior of the genital system in both men and women. Caregivers should be informed regarding normal pelvic floor function in general and should be able to identify specific aspects of pelvic floor dysfunction in patients with related symptoms. In our hospital, this diagnostic consultation is indicated as Diagnostic Investigation of Pelvic Floor Function (DIPFF). AIM: This study looked at pelvic floor dysfunction related to specific complaints. METHODS: DIPFF consists of a medical history, a physical examination, including the International Continence Society (ICS) pelvic organ prolapse quantification system in female patients, and a biofeedback registration using a vaginal or anal probe. Based on our experience, we defined an elevated rest tone as greater than 2 microV using intravaginal or intra-anal electromyography. MAIN OUTCOME MEASURES: Stratification of patients with a single complaint, a combination of two or three complaints of the micturition, defecation or sexual (all compartments of the pelvic floor) resulted in subgroups of respectively 30, 74, and 133 patients. RESULTS: A total of 238 patients with complaints of micturition, defecation, and/or sexual function were included in this study. Electromyographic analysis revealed an elevated rest tone of the pelvic floor in 141 patients. In 184 patients, we found an involuntary relaxation of the pelvic floor. CONCLUSION: In our retrospective study, we found that 77.2% of patients who presented to the clinic with urinary, gastro or sexual complaints had measurable pelvic floor dysfunction (69.3% overactive rest tone and 7.9% under active rest tone). In relation to the ICS terminology, there is a need for a well-defined normal vs. elevated rest tone of the pelvic floor.

Development and validation of the pelvic floor inventories Leiden (PelFIs).

AIMS: To evaluate the validity and reliability in Dutch of the Pelvic Floor Inventories Leiden (PelFIs) for men and women, an administered questionnaire, developed to create a condition-specific pelvic floor questionnaire addressing all symptoms of micturition, defecation and sexual dysfunction related to pelvic floor dysfunction. METHODS: The PelFIs is an 83-item instrument for women and 76-item instrument for men measuring the degree of pelvic floor dysfunction, containing nine different domains. Questions have been selected which, from a clinical point of view, should configure a domain. The PelFIs was administered to healthy volunteers (N = 120), and to patients (N = 100). Reliability of the PelFIs was assessed by internal consistency and test-retest reliability. Construct validity was established comparing healthy volunteers and patients by intercorrelating the domains. RESULTS: A total of 220 questionnaires were completed; by 147 women and 73 men. Some domains in the men's questionnaire had a low alpha (alpha) although the overall alpha was good. The overall of the domains for men ranged from 0.53 to 0.90. The internal consistency for the total scale of men's questionnaire was 0.84. The overall of the domains in women ranged from 0.60 to 0.85. The internal consistency of the women's questionnaire was 0.88 for the total scale. Intraclass correlation ranged from 0.65 to 0.88. Differences between healthy volunteers and patients were statistically significant for all domains. CONCLUSION: The PelFIs is a new, practical and conceptually clear questionnaire, which focus on micturition, defecation and/or sexual dysfunction related to pelvic floor dysfunction.

How reliable is a self-administered questionnaire in detecting sexual abuse: a retrospective study in patients with pelvic-floor complaints and a review of literature.

INTRODUCTION: Sexual abuse and sexual functioning are topics that health professionals find difficult to discuss. Women who present with pelvic-floor complaints often experience sexual difficulties; therefore, questions regarding sexual function should be a routine part of screening. Furthermore, pelvic-floor complaints are correlated with sexual abuse and asking about abuse should be a routine part of screening as well. Considering the fact that many practitioners have difficulty enquiring about abuse, we have suggested that a questionnaire may be helpful in improving the recognition and management of patients who have a history of sexual abuse. AIM: The efficiency of detecting sexual abuse by a self-administered questionnaire. METHODS: Report of sexual abuse in a self-administered pelvic-floor questionnaire before visiting our outpatient pelvic-floor department was evaluated with the Pelvic Floor Leiden Inventories (PelFIs) administered by a pelvic- floor clinician in a later stage. MAIN OUTCOME MEASURES: The percentage of sexual abuse detected by a taken questionnaire administered by a pelvic-floor clinician not confessed during a previous self-administered questionnaire. RESULTS: Sexual abuse was reported in 20 patients with pelvic-floor dysfunction during administration of the PelFIs and were also evaluated on our pelvic-floor department. Only six of the patients (30%) did not note in the self-administered questionnaire that they had a history of sexual abuse. CONCLUSION: A self-administered questionnaire for pelvic-floor complaints is reliable in detecting sexual abuse and can be helpful in daily practice.

Placement of probes in electrostimulation and biofeedback training in pelvic floor dysfunction.

BACKGROUND: We examined the positioning of five commonly used probes in electrostimulation and biofeedback training. MATERIALS AND METHODS: Ultrasound and MRI were used to evaluate the position of these probes in two multiparous women, in reference to pelvic floor anatomy. RESULTS: From caudal to cranial we identified the anal external sphincter, puborectal muscle, and levator group. Positioning of probes varied considerably: the recording plates are situated from 1 cm caudal to 6 cm cranial of the puborectal muscle. Most probes stretched, due to a relatively large diameter, the vagina wall, anal external sphincter, or puborectal muscle beyond physiological proportions. On straining, all probes were pushed upwards into the rectum. CONCLUSION: The positioning of all examined probes varied considerably. Hence it is not likely that these probes give a reliable and uniform registration of muscular activity of the pelvic floor function or are all optimal for electrostimulation.

Effects of magnetic stimulation in the treatment of pelvic floor dysfunction.

OBJECTIVE: To correlate, in a pilot study, the clinical results of extracorporeal magnetic innervation therapy (ExMI) of the pelvic floor muscles with functional changes in the pelvic floor musculature, urodynamics and quality of life. PATIENTS AND METHODS: In all, 74 patients (65 women and nine men) with urge incontinence, urgency/frequency, stress incontinence, mixed incontinence and defecation problems were included in a prospective study of ExMI using a 'electromagnetic chair'. All patients were treated twice weekly for 8 weeks. Digital palpation and biofeedback with a vaginal or anal probe were used for registration of the pelvic floor musculature. A urodynamic evaluation, a voiding diary, a pad-test, the King's Health Questionnaire (KHQ) and a visual analogue scale (VAS) were completed by the patient at baseline and at the end of the study. RESULTS: In the group as a whole, there were no significant differences in the voiding diary, pad-test, quality of life, VAS score, biofeedback registration and urodynamics before and after treatment. Additional stratification was applied to the total patient group, related to the pretreatment rest tone of the pelvic floor, the basal amplitude registered on electromyography, to age and to previous treatments. However, there were no significant differences in the data before and after treatment within all subgroups (stress incontinence, urge incontinence, urgency/frequency, defecation problems, overactive pelvic floor, age, previous treatments), except for the KHQ domain of 'role limitations', where there was a significant improvement in all groups. CONCLUSION: ExMI did not change pelvic floor function in the present patients. The varying outcomes of several studies on ExMI stress the need for critical studies on the effect and the mode of action of electrostimulation and magnetic stimulation. In our opinion 'the chair' is suitable to train awareness of the location of the pelvic floor. However, active pelvic floor muscle exercises remain essential.
