Pessary management practices for pelvic organ prolapse among Australian health care practitioners: a cross-sectional study.

INTRODUCTION AND HYPOTHESIS: Vaginal pessaries are a low-cost, effective treatment for pelvic organ prolapse (POP) and an alternative to surgery. Whilst traditionally pessary management (PM) has been provided by medical professionals, particularly gynaecologists, recent international studies found other professionals, including physiotherapists and nurses, may be involved. It is unknown which health care practitioners (HCPs) provide PM for POP in Australia or the distribution of services. METHODS: In a cross-sectional study design, a self-reported electronic survey investigated Australian HCPs providing PM for POP. Purposive and snowball sampling targeted HCPs, professional organisations and health care facilities. Descriptive statistics described PM in relation to HCP professional profile, PM provision and geographical location. RESULTS: There were 536 respondents (324 physiotherapists, 148 specialists, 33 general practitioners (GPs) and 31 nurses providing PM. Most worked within metropolitan regions (n = 332, 64%), 140 (27%) in rural, 108 (21%) in regional and 10 (2%) in remote areas. Most worked privately (n = 418, 85%), 153 (46%) worked publicly and 85 (17%) in both. Ring pessaries were most commonly used, followed by cube and Gellhorn. HCPs reported variable training in PM, and 336 (69%) had no mandatory workplace competency standard; however, 324 (67%) wanted further training. Women travelled long distances to access services. CONCLUSIONS: Doctors, nurses and physiotherapists provided PM in Australia. HCPs had variable training and experience in PM, with rural and remote HCPs particularly wanting further training. This study highlights the need for accessible PM services, standardised and competency-based training for HCPs, and governance structures ensuring safe care.

The relationship between symptom severity, bother and psychological factors in women with pelvic organ prolapse: A cross-sectional observational study.

AIM: The primary aim is to explore the relationship between symptom severity and prolapse bother in women with pelvic organ prolapse (POP). The secondary aim is to determine the association between psychological variables and prolapse bother. METHODS: A cross-sectional observational study was conducted via online surveys assessing POP bother (visual analog scale for bother), POP symptom severity (International Consultation on Incontinence Questionnaire-Vaginal Symptoms), and psychological measures of depression and anxiety (Kessler psychological distress scale [K-10]), catastrophizing (modified pain catastrophizing scale [mPCS]), and self-efficacy (modified pain self-efficacy questionnaire [mPSEQ]) in women with self-reported POP. Symptom severity, bother and psychological variables were analyzed using linear regression. RESULTS: Seventy-six women with a mean (SD) age of 42.8 (14.57) years were included in analysis. A moderate to strong positive linear relationship (R2 = 0.449, p < 0.001) was found between symptom severity and POP bother. Prolapse bother and psychological variables were moderately correlated, where increased K-10 scores (R2 = 0.230, p = 0.001), higher mPCS scores (R2 = 0.460, p < 0.001), and lower mPSEQ scores (R2 = 0.460, p < 0.001) were associated with increased POP bother. Moderate and severe catastrophizing was associated with significantly higher POP bother, with mean POP bother scores of 7.861 ± 0.45 (p < 0.001) and 8.652 ± 0.45 (p < 0.001), respectively. CONCLUSION: A moderate positive relationship between POP bother and symptom severity was found, with greater psychological distress and lower self-efficacy associated with increasing POP bother. Women presenting with POP should be screened for psychological factors to guide management.

Development of a multinational, multidisciplinary competency framework for physiotherapy training in pessary management: an E-Delphi study.

INTRODUCTION AND HYPOTHESIS: Vaginal support pessaries are intravaginal devices designed to relieve symptoms of pelvic organ prolapse, but they can cause serious medical complications if not managed well. Physiotherapists are well placed to manage pessaries, but there are no guidelines on the training required for competency in pessary management (PM). METHODS: A scoping review of current literature on PM training was conducted to develop draft competency standards, which were reviewed by a multidisciplinary focus group. Using e-Delphi methodology, a multidisciplinary and multinational expert panel then refined the standards. Three rounds of e-Delphi online surveys were conducted, with individual participant feedback and one videoconference to discuss items that did not reach consensus. Consensus was set at 80% agreement and stability measured using kappa coefficient. RESULTS: Pessary training competency standards, developed by 29 experts, covered three key domains including: (1) prerequisite knowledge and understanding; (2) entrustable professional activities; (3) pessary-specific standards under ten key roles. Consensus was reached on all 73 (100%) competency standards and stability demonstrated for 95.9% of standards. There was no attrition of expert panel participants through the e-Delphi rounds. CONCLUSIONS: This e-Delphi study provides the first, robust recommendations on training standards for physiotherapists in PM. These competency standards will provide clinicians with a self-assessment tool, and educators and training institutions with a benchmark in training for PM, which should improve options and reduce risk for women with prolapse being managed with a pessary.

Do features of randomized controlled trials of pelvic floor muscle training for postprostatectomy urinary incontinence differentiate successful from unsuccessful patient outcomes? A systematic review with a series of meta-analyses.

AIMS: Efficacy of pelvic floor muscle training (PFMT) for postprostatectomy incontinence (PPI) differs between randomized clinical trials (RCT). This might be explained by variation in content/delivery of PFMT (eg, biofeedback, muscles targeted, and time of commencement of training). This review investigated whether outcome of meta-analysis differs based on presence or not of specific RCT features. METHODS: PubMed, CINAHL, EMBASE, Physiotherapy Evidence Database (PEDro), and Cochrane were searched for RCTs that investigated efficacy of PFMT on PPI. PFMT details and outcomes were extracted. Methodological quality and comprehensiveness of PFMT reporting was assessed using the PEDro scale and Consensus on Reporting Template, respectively. Effect size and 95% confidence intervals were calculated for incontinence rate at 3 months. To identify features that influenced efficacy, separate meta-analyses were performed for studies with and without specific features. RESULTS: Twenty-two trials were included, and 15 were used for meta-analysis of 3-month outcomes. Overall, meta-analysis showed reduced incontinence with PFMT (risk ratio [RR] = 0.85; I2 = 55%; P = .005). Meta-analyses showed better outcomes for PFMT than control groups when the study included preoperative PFMT (RR = 0.76; I2 = 30%; P = .006), biofeedback (RR = 0.73; I2 = 58%; P = .006), instruction to contract around the urethra (RR = 0.9; I2 = 43%; P = .009), a control group without PFMT instruction (RR = 0.85; I2 = 69%; P = .05), inclusion of all men irrespective of continence status (RR = 0.84; I2 = 30%; P = .003) and continence defined as no leakage (RR = 0.85; I2 = 48%; P = .05). CONCLUSIONS: Preoperative PFMT, biofeedback, urethral instructions, no PFMT instruction for controls, inclusion of all men, and continence defined as no leakage are features associated with successful patient outcomes. Future studies should consider these features in design of interventions and pooling data for meta-analysis.

Motor, cognitive and mobility deficits in 1000 geriatric patients: protocol of a quantitative observational study before and after routine clinical geriatric treatment - the ComOn-study.

BACKGROUND: Motor and cognitive deficits and consequently mobility problems are common in geriatric patients. The currently available methods for diagnosis and for the evaluation of treatment in this vulnerable cohort are limited. The aims of the ComOn (COgnitive and Motor interactions in the Older populatioN) study are (i) to define quantitative markers with clinical relevance for motor and cognitive deficits, (ii) to investigate the interaction between both motor and cognitive deficits and (iii) to assess health status as well as treatment outcome of 1000 geriatric inpatients in hospitals of Kiel (Germany), Brescia (Italy), Porto (Portugal), Curitiba (Brazil) and Bochum (Germany). METHODS: This is a prospective, explorative observational multi-center study. In addition to the comprehensive geriatric assessment, quantitative measures of reduced mobility and motor and cognitive deficits are performed before and after a two week's inpatient stay. Components of the assessment are mobile technology-based assessments of gait, balance and transfer performance, neuropsychological tests, frailty, sarcopenia, autonomic dysfunction and sensation, and questionnaires to assess behavioral deficits, activities of daily living, quality of life, fear of falling and dysphagia. Structural MRI and an unsupervised 24/7 home assessment of mobility are performed in a subgroup of participants. The study will also investigate the minimal clinically relevant change of the investigated parameters. DISCUSSION: This study will help form a better understanding of symptoms and their complex interactions and treatment effects in a large geriatric cohort.

"I wish I knew then what I know now" - pain science education concepts important for female persistent pelvic pain: a reflexive thematic analysis.

ABSTRACT: Pain science education (PSE) provides people with an understanding of "how pain works" grounded in the biopsychosocial model of pain; it has been demonstrated to improve outcomes in musculoskeletal pain conditions. Preliminary evidence suggests PSE may be effective for female individuals with persistent pelvic pain, but how the content of PSE needs to be modified for this group remains to be determined. A reflexive thematic analysis of qualitative data was performed to identify PSE concepts that female individuals with persistent pelvic pain consider important and why. Twenty individual, semistructured interviews were conducted with adult females who had engaged with PSE and had self-identified as having "improved" pelvic pain. Most participants had been diagnosed with endometriosis (n = 16). Four themes were generated capturing PSE concepts considered important by female individuals with "improved" pelvic pain: (1) "A sensitised nervous system leads to overprotective pain" validated their pelvic pain as being real; (2) "Pain does not have to mean the body is damaged (although sometimes it does)" provided reassurance that pelvic pain does not mean their condition is worsening; (3) "How I think, feel, and 'see' my pain can make it worse" enabled participants to find optimal ways to manage their pain; and (4) "I can change my pain… slowly" provided hope that pelvic pain can improve and empowered them to pursue pain improvement as a viable goal. This study generated 4 PSE learning concepts that were important to female individuals with improved pelvic pain and may be incorporated into PSE curricula for female individuals with pelvic pain.

The Efficacy of Self-Management Strategies for Females with Endometriosis: a Systematic Review.

Self-management is critical for the care of endometriosis. Females with endometriosis frequently use self-management strategies to manage associated symptoms; however, the efficacy of such strategies is unknown. The aim of this review was to systematically appraise the evidence concerning efficacy of self-management strategies for endometriosis symptoms. Electronic databases, including Medline, Embase, Emcare, Web of Science Core Collection, Scopus, and the Cochrane Central Register of Controlled Trials, were searched from inception to March 2021. We included peer-reviewed experimental studies published in English evaluating the efficacy of self-management strategies in human females laparoscopically diagnosed with endometriosis. Studies underwent screening, data extraction, and risk of bias appraisal (randomised studies: Risk of Bias 2 tool; non-randomised studies: Risk Of Bias In Non-randomized Studies - of Interventions tool). Of the fifteen studies included, 10 evaluated dietary supplements, three evaluated dietary modifications, one evaluated over-the-counter medication, and one evaluated exercise. Most studies had a high-critical risk of bias. Many self-management strategies were not more effective at reducing endometriosis symptoms compared to placebo or hormonal therapies. Where studies suggest efficacy for self-management strategies, no recommendations can be made due to the poor quality and heterogeneity of evidence. High-quality empirical evidence is required to investigate the efficacy of self-management strategies for females with endometriosis.

How Might We Screen for Psychological Factors in People With Pelvic Pain? An e-Delphi Study.

OBJECTIVE: Persistent pelvic pain (PPP) is a complex condition often influenced by psychological factors that can alter treatment outcomes. These factors are potentially modifiable; however, currently there is no instrument to screen for them. The purpose of this study was to determine: (1) which psychological factors should be screened in individuals with PPP, and (2) the most appropriate statements to represent these psychological factors. METHODS: The study used a focus group design followed by an electronic-Delphi (e-Delphi) process. A focus group consisting of 8 experts was conducted to determine the relevant psychological factors to screen. These results informed round 1 of the e-Delphi process, consisting of a panel of 14 pain/pelvic pain experts. The e-Delphi process consisted of 3 rounds of online surveys and 2 teleconference discussions to establish consensus on the most appropriate statement to screen for each of the psychological factors. RESULTS: The focus group identified 13 relevant psychological factors. During the e-Delphi process, relevant screening statements were assessed using a 100-point allocation system. Experts could reword and suggest new statements. Statements were assessed for consensus and stability and were eliminated as the rounds progressed if they met the exclusion criteria. At the termination of round 3, there were 15 statements remaining. CONCLUSION: The final list of 15 statements will assist clinicians in screening for psychological factors and is an important step for clinicians in providing psychologically informed care to people with PPP. Future research should determine the psychometric properties of the statements to determine their clinical utility as a questionnaire. IMPACT: This study has refined a list of statements to help screen for psychological factors in individuals with PPP. Developed robustly using an e-Delphi method, this list is an important first step forward for clinicians to provide psychologically informed care to these individuals.

Reconsideration of pelvic floor muscle training to prevent and treat incontinence after radical prostatectomy.

Urinary incontinence is common after radical prostatectomy. Pelvic floor muscle training provides a plausible solution. Although early trials provided promising results, systematic reviews have questioned the efficacy of this intervention. A major consideration is that most clinical trials in men have applied principles developed for pelvic floor muscle training for stress urinary incontinence in women, despite differences in anatomy between sexes and differences in the mechanisms for continence/incontinence. Literature regarding continence control in men has been conflicting and often based on erroneous anatomy. New understanding of continence mechanisms in men, including the complex contribution of multiple layers of striated pelvic floor muscles, and detailed consideration of the impact of radical prostatectomy on continence anatomy and physiology, have provided foundations for a new approach to pelvic floor muscle training to prevent and treat incontinence after prostatectomy. An approach to training can be designed to target the pathophysiology of incontinence. This approach relies on principles of motor learning and exercise physiology, in a manner that is tailored to the individual patient. The aims of this review are to consider new understanding of continence control in men, the mechanisms for incontinence after radical prostatectomy, and to review the characteristics of a pelvic floor muscle training program designed to specifically target recovery of continence after prostatectomy.

An argument for competency-based training in pelvic floor physiotherapy practice.

Pelvic floor dysfunction has been described as "a silent epidemic," affecting many people in the community yet under-recognized and insufficiently managed. There is evidence that pelvic floor physiotherapy can manage many of these disorders, however a competency framework to guide and inform pelvic floor physiotherapy training and practice is lacking. The assessment and management of the pelvic floor complex is not addressed as a core component of most entry-to-practice physiotherapy programs despite being within the scope of physiotherapy practice which is in contrast with the knowledge and skills that physiotherapists graduate with in core areas of clinical practice. This results in a registration-competency gap, and the need for post-graduation training to ensure clinicians are appropriately skilled to practice safely and effectively in this area. In addition, there are potential ethical and legal issues unique to this area of physiotherapy practice to be considered. We use a series of clinical scenarios to highlight the domains of knowledge, skills and communication required for practice in this area, based on our experience in Australia. We propose a framework for the future which defines competence in pelvic floor physiotherapy to provide clarity to clinicians about their clinical, ethical and legal obligations to the public, our referrers and third-party payers.

Physiotherapy for urinary incontinence.

BACKGROUND: International guidelines recommend treatment for urinary incontinence by a health professional such as a pelvic floor or continence physiotherapist with specialised training in the management of pelvic floor disorders. OBJECTIVE: This article discusses the role of a physiotherapy program in treating women with urinary incontinence. DISCUSSION: Treatment usually involves five consultations with a pelvic floor physiotherapist over 4-6 months. After an assessment of bladder function and the pelvic floor muscles, an individualised training program is prescribed. The focus of pelvic floor muscle training is to build strength, endurance, speed and the coordination of the pelvic floor muscles in different situations. An effective program has been shown to increase contractile strength as well as increased resting tone of the pelvic floor, which then provides improved support of the pelvic organs higher in the pelvis. Women may be offered an annual review by their physiotherapist in order to promote long term continence.

The Role of Preoperative Puborectal Muscle Function Assessed by Transperineal Ultrasound in Urinary Continence Outcomes at 3, 6, and 12 Months After Robotic-Assisted Radical Prostatectomy.

PURPOSE: The efficacy of pelvic floor muscle training (PFMT) for men with postprostatectomy incontinence (PPI) after robotic-assisted radical prostatectomy (RARP) is controversial and the mechanism for its possible effect remains unclear. The aim of this study was to investigate the relationship between bladder neck (BN) displacement, as a proxy for puborectal muscle activation, and continence outcomes after RARP. METHODS: Data were extracted from the South Australian Prostate Cancer Clinical Outcomes Collaborative database for men undergoing RARP by high volume surgeons who attended preoperative pelvic floor physiotherapy for pelvic floor muscle (PFM) training between 2012 and 2015. Instructions were to contract the PFM as if stopping the flow of urine. BN displacement was measured with 2-dimensional transperineal ultrasound, without digital rectal examination. Urinary continence status was assessed preoperatively and at 3, 6, and 12 months using the Expanded Prostate Cancer Index Composite 26. Data were analysed using logistic regression and mixed effects linear modelling. Confounding variables considered were baseline continence, age at diagnosis, margin status, nerve sparing procedures and pathological stage. RESULTS: Of 671 eligible men, 358 met the inclusion criteria and were available for analysis, with 136 complete datasets at 12-month follow-up. While BN movement was associated with preoperative continence, there was no significant effect of BN displacement on the change in urinary continence at 12 months postprostatectomy (P=0.81) or on the influence of time on continence over 3-12 months. CONCLUSIONS: Continence outcomes were not associated with BN displacement, produced by activity of the puborectal portion of the levator ani muscle, at 3, 6, or 12 months after RARP. These results suggest that the puborectal muscle does not play a role in the recovery of continence after RARP and may help to explain the negative findings of many studies of PFMT for PPI.

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 costs and benefits of physiotherapy as first-line treatment for female stress urinary incontinence.

OBJECTIVE: To evaluate the costs and benefits of physiotherapy for stress urinary incontinence (SUI) in Australia. METHODS: We evaluated the costs and benefits of physiotherapy for the treatment of SUI using outcome data from a prospective multicentre observational study conducted in 1999/2000. Women presenting with SUI to physiotherapists trained in continence management in 35 centres across Australia were recruited into the study. The outcomes of treatment were assessed using subjective, objective and quality-of-life measures at the conclusion of treatment and with 12-month follow-up. The number of treatments in an average episode of care was calculated and adverse events were recorded. RESULTS: Of the 274 consenting subjects, 208 completed an episode of physiotherapy care consisting of a median (IQ range) of five (4-6) visits. The estimated average costs for an episode of ambulatory physiotherapy treatment were dollar 302.40. Based on 'intention to treat' principles, 64% of women were objectively cured. There was a clinically and statistically significant improvement (p < 0.05) in all outcomes after treatment and these were maintained at one-year follow-up. No adverse events were reported. CONCLUSIONS AND IMPLICATIONS: Specialised ambulatory physiotherapy for SUI in Australia is a low-cost, low-risk and effective treatment. These results provide evidence to support international recommendations that physiotherapy should be routinely implemented as first-line treatment before consideration of surgery. This information has important economic implications for planning future health services.

Comparison of transperineal and transabdominal ultrasound in the assessment of voluntary pelvic floor muscle contractions and functional manoeuvres in continent and incontinent women.

Transperineal (TP) and transabdominal (TA) ultrasounds were used to assess bladder neck (TP) and bladder base (TA) movement during voluntary pelvic floor muscle (PFM) contraction and functional tasks. A sonographer assessed 60 asymptomatic (30 nulliparous, 30 parous) and 60 incontinent (30 stress, 30 urge) women with a mean age of 43 (SD=7) years, BMI of 24 (SD=4) kg m2 and a median parity of 2 (range, 0-5), using both ultrasound methods. The mean of three measurements for bladder neck and bladder base (sagittal view) movement for each task was assessed for differences between the groups. There were no differences in bladder neck (p=0.096) or bladder base (p=0.112) movement between the four groups during voluntary PFM contraction but significant differences in bladder neck (p<0.004) and a trend towards differences in bladder base (p=0.068) movement during Valsalva and abdominal curl manoeuvre. During PFM contraction, there was a strong trend for the continent women to have greater bladder neck elevation (p=0.051), but no difference in bladder base movement (p=0.300), when compared to the incontinent women. The incontinent women demonstrated increased bladder neck descent during Valsalva and abdominal curl (p<0.001) and bladder base descent during Valsalva (p=0.021). The differences between the groups were more marked during functional activities, suggesting that comprehensive assessment of the PFM should include functional activities as well as voluntary PFM contractions. TP ultrasound was more reliable and takes measures from a bony landmark when compared to TA ultrasound, which lacks a reference point for measurements. TA ultrasound is less suitable for PFM measures during functional manoeuvres and comparisons between subjects. Few subjects were overweight so the results may not be valid in an obese population.

Differences in muscle activation patterns during pelvic floor muscle contraction and Valsalva maneuver.

AIMS: To investigate the different muscle activation patterns around the abdomino-pelvic cavity in continent women and their effect on pressure generation during a correct pelvic floor muscle (PFM) contraction and a Valsalva maneuver. METHODS: Thirteen continent women were assessed. Abdominal, chest wall, and PFM activity and vaginal and intra-abdominal pressure (IAP), were recorded during two tasks: PFM contraction and Valsalva whilst bladder base position was monitored on trans-abdominal ultrasound. A correct PFM contraction was defined as one that resulted in bladder base elevation and a Valsalva resulted in bladder base depression. RESULTS: Comparison of the mean of the normalized EMG activity of all the individual muscle groups was significantly different between PFM contraction and Valsalva (P = 0.04). During a correct PFM contraction, the PFM were more active than during Valsalva (P = 0.001). During Valsalva, all the abdominal muscles (IO (P = 0.006), EO (P < 0.001), RA (P = 0.011)), and the chest wall (P < 0.001) were more active than during PFM contraction. The change in IAP was greater during Valsalva (P = 0.001) but there was no difference in the change in vaginal pressure between PFM contraction and Valsalva (P = 0.971). CONCLUSIONS: This study demonstrates a difference in muscle activation patterns between a correct PFM contraction and Valsalva maneuver. It is important to include assessment of the abdominal wall, chest wall, and respiration in the clinical evaluation of women performing PFM exercises as abdominal wall bracing combined with an increase in chest wall activity may cause rises in IAP and PFM descent.

Altered muscle activation patterns in symptomatic women during pelvic floor muscle contraction and Valsalva manouevre.

AIMS: To investigate the muscle activation patterns of the abdomino-pelvic region used by incontinent women during a pelvic floor muscle (PFM) contraction and a Valsalva manouevre compared to healthy, asymptomatic subjects. METHODS: Thirteen incontinent (symptomatic) women, identified using ultrasound to be consistently depressing the bladder base during PFM contraction, and thirteen continent women (asymptomatic) able to perform an elevating PFM contraction were assessed using surface electromyography (EMG) of the PFM, abdominal and chest wall muscles and vaginal and intra-abdominal pressure (IAP) measurements during PFM contraction and Valsalva under ultrasound surveillance. RESULTS: There were no differences between groups in age, parity or BMI. There was a difference in muscle activation patterns between groups (P = 0.001). During PFM contraction the PFM were less active and the abdominal and chest wall muscles were more active in the symptomatic group. During Valsalva, the PFM and EO were more active in the symptomatic group but there was no difference in the activation of the other muscles between groups. There was a significant interaction (group x pressure) for change in IAP (P = 0.047) but no significant interaction for change in vaginal pressure (VP) (P = 0.324). CONCLUSIONS: The symptomatic women displayed altered muscle activation patterns when compared to the asymptomatic group. The symptomatic women were unable to perform a voluntary PFM contraction using a localized muscle strategy, instead activating all the muscles of the abdomino-pelvic cavity. The potential for muscle substitution strategies reinforces the need for close attention to specificity when prescribing PFM exercise programs.

Assessment of voluntary pelvic floor muscle contraction in continent and incontinent women using transperineal ultrasound, manual muscle testing and vaginal squeeze pressure measurements.

The aims of the study were: (1) to assess women performing voluntary pelvic floor muscle (PFM) contractions, on initial instruction without biofeedback teaching, using transperineal ultrasound, manual muscle testing, and perineometry and (2) to assess for associations between the different measurements of PFM function. Sixty continent (30 nulliparous and 30 parous) and 60 incontinent (30 stress urinary incontinence (SUI) and 30 urge urinary incontinence (UUI)) women were assessed. Bladder neck depression during attempts to perform an elevating pelvic floor muscle (PFM) contraction occurred in 17% of continent and 30% of incontinent women. The UUI group had the highest proportion of women who depressed the bladder neck (40%), although this was not statistically significant (p=0.060). The continent women were stronger on manual muscle testing (p=0.001) and perineometry (p=0.019) and had greater PFM endurance (p<0.001) than the incontinent women. There was a strong tendency for the continent women to have a greater degree of bladder neck elevation than the incontinent women (p=0.051). There was a moderate correlation between bladder neck movement during PFM contraction measured by ultrasound and PFM strength assessed by manual muscle testing (r=0.58, p=0.01) and perineometry (r=0.43, p=0.01). The observation that many women were performing PFM exercises incorrectly reinforces the need for individual PFM assessment with a skilled practitioner. The significant correlation between the measurements of bladder neck elevation during PFM contraction and PFM strength measured using MMT and perineometry supports the use of ultrasound in the assessment of PFM function; however, the correlation was only moderate and, therefore, indicates that the different measurement tools assess different aspects of PFM function. It is recommended that physiotherapists use a combination of assessment tools to evaluate the different aspects of PFM function that are important for continence. Ultrasound is useful to determine the direction of pelvic floor movement in the clinical assessment of pelvic floor muscle function in a mixed subject population.
