Responsiveness of the Spanish Pelvic Floor Distress Inventory and Pelvic Floor Impact Questionnaires Short Forms (PFDI-20 and PFIQ-7) in women with pelvic floor disorders

The Effectiveness of Adding Transvaginal Radiofrequency to Pelvic Floor Muscle Training for 6 Weeks in Women with Stress Urinary Incontinence. A Double-Blind Randomised Controlled Trial

INTRODUCTION AND HYPOTHESIS

The objective was to evaluate the clinically beneficial effect of adding transvaginal monopolar non-ablative radiofrequency (RF) to pelvic floor muscle training (PFMT) on leakage severity, quality of life and urinary incontinence-related symptoms in women with stress urinary incontinence (SUI).

METHODS

A double-blind randomised controlled trial was conducted, with a 6-week intervention and a 6-month follow-up. Participants were randomly assigned to the experimental group (PFMT plus RF; n = 18) or the control group (PFMT plus placebo; n = 20). The primary outcome was the International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF). Secondary outcomes included the Pelvic Floor Distress Inventory-20 (PFDI-20) and the Pelvic Floor Impact Questionnaire-7 (PFIQ-7), self-efficacy, female sexual function, pelvic floor muscle dynamometry, 1-h pad test and number of SUI episodes per week. Inferential analyses of the data were performed using a two-factor analysis of variance.

RESULTS

Both groups achieved a statistically significant improvement in ICIQ-SF over time. However, the differences observed in the experimental group exceeded the minimal clinically important differences by 4 points (MD = -9.4, 95% CI = -12.6 to -6.3), which was not observed in the control group (MD = -3.9, 95% CI = -6.9 to -1.0). This was maintained at the 6-month follow-up with a significant time*group interaction (p < 0.001, ηp2 = 0.150). There was no time*group interaction in the other variables (p > 0.05). Additionally, a significant difference in favour of the experimental group was observed in the 1-h pad test and episodes of SUI per week (p < 0.05).

CONCLUSIONS

This study highlights the beneficial effects of adding transvaginal RF to PFMT on the severity and amount of leakage, as well as on the quality of life and urinary incontinence-related symptoms in women with moderate SUI. Future trials are needed to assess the effects of this intervention in women with severe SUI.

Correlation of Self-Efficacy for Pelvic Floor Muscle Exercise with Symptoms of Stress Urinary Incontinence in Women

INTRODUCTION AND HYPOTHESIS

Self-efficacy for pelvic floor exercises, i.e. confidence in achieving pelvic floor contractions, may predict adherence to treatment. However, there is a paucity of literature investigating the clinical relevance of this outcome. The aim was to determine the relationship between self-efficacy for pelvic floor exercise and symptom severity, pelvic floor distress and impact on quality of life, as well as sociodemographic characteristics and pelvic floor muscle strength in women with stress urinary incontinence (SUI).

METHODS

A cross-sectional study was conducted in women with SUI. The Spanish version of the Broome Pelvic Muscle Self-Efficacy Scale was used to assess self-efficacy for pelvic floor exercise. The dependent variables were: urinary incontinence symptoms using the International Consultation on Incontinence Questionnaire, short form (ICIQ-SF), pelvic floor distress symptoms using the Urogenital Distress Inventory-6, impact on quality of life using the Incontinence Impact Questionnaire (IIQ-7), leakage using the 1-h pad test, number of SUI episodes per week and pelvic floor muscle strength.

RESULTS

A total of 56 women with a median age of 44.5 years were included. Self-efficacy for pelvic floor exercise correlated negatively and moderately with the ICIQ-SF (r = -0.529; p < 0.001), IIQ-7 (r = -0.442; p = 0.001), 1-h pad test (rs = -0.467; p < 0.001); and number of SUI episodes/week (rs = -0.489; p < 0.001). Correlation with the other outcomes was weak or non-existent. Linear regression with forward selection showed that the ICIQ-SF was the variable most related to self-efficacy (β: -3.01, 95% CI: -4.03 to -1.69).

CONCLUSIONS

These findings highlight the importance of assessing self-efficacy for pelvic floor exercise in the treatment of women with SUI. Future prospective studies are needed to confirm these findings.

Effects of hypopressive exercises on post-partum abdominal diastasis, trunk circumference, and mechanical properties of abdominopelvic tissues: a case series

BACKGROUND

Abdominal diastasis (AD) is highly prevalent at post-partum. Although several conservative approaches have been proposed, an effective and protocolized treatment is lacking for this condition.

OBJECTIVE

To identify modifications of inter-rectus abdominis distance (IRAD), trunk circumferences and mechanical properties of the AD, transversus abdominis and the pelvic floor (PF) muscles, after the application of hypopressive exercises (HE) and at a two-month follow-up in postpartum AD.

METHODS

Twelve volunteers with post-partum AD followed a four-week (three times a week) tailored program of HE. The main outcome was the IRAD, assessed at four specific supraumbilical points (3, 6, 9, and 12 cm). Abdominal circumference and respiratory expansion were measured at three different locations (axillar, xiphoid, and umbilical), and the mechanical properties of abdomino-pelvic tissues were also assessed using tonometry (MyotonPRO). Four evaluations were performed for all outcomes: at baseline, post-intervention, at a 1-month follow-up, and at a 2-month follow-up.

RESULTS

The IRAD of participants was reduced (p < .05), furthermore, some participants displayed no AD after the intervention period. In addition, the abdominal circumference increased, mainly at follow-up, whereas the thoracic respiratory expansion decreased a median of 2 cm. The tension and stiffness of the LA decreased, when assessed at 3 and 6 cm supraumbilical. Finally, the tension and elasticity of TA/IO and of the PF, and also the elasticity of the PF decreased after the intervention period. No complaints were identified in relation to the HE program or assessments.

CONCLUSION

A program of HE showed positive results for the reduction of post-partum AD. Different study designs should be performed to better explain the effects of HE for AD.

Cross-cultural adaptation and measurement property analysis of the Brazilian Portuguese version of the Three Incontinence Questionnaire

INTRODUCTION AND HYPOTHESIS

The differential diagnosis of urinary symptoms may allow health professionals to establish a therapeutic objective and to choose the appropriate treatment for the patient's complaint. The aim of this study was to cross-culturally adapt the Three Incontinence Questionnaire (3IQ) into Brazilian Portuguese (3IQ-Br) and to analyze test-retest reliability, construct, and criterion validity in women.

METHODS

The cross-cultural adaptation of the 3IQ-Br included forward-translation, back-translation, and consensus among an expert committee. Participants with and without urinary incontinence (UI) completed the 3IQ-Br, King's Health Questionnaire (KHQ), and Questionnaire for Female Urinary Incontinence Diagnosis (QUID-Br). Only women with UI answered 3IQ-Br after 7-10 days. Test-retest reliability and construct validity were analyzed using the Cohen linear kappa (k). The 3IQ-Br accuracy was analyzed using the area under the curve (AUC) of the receiver-operating characteristic (ROC) curve, considering the sensitivity and specificity to correctly classify women with and without UI.

RESULTS

The reliability of each question from the 3IQ-Br was considered substantial in the test-retest. The agreement among 3IQ-Br, QUID-Br, and KHQ was almost perfect for UI diagnosis (k > 0.8). The 3IQ-Br was considered to have good accuracy in distinguishing women with UI considering the KHQ (AUC 0.83, 95% confidence interval [CI] 0.78 to 0.87, p < 0.001), and fair to the QUID-Br (AUC 0.73, 95% CI 0.68 to 0.78; p < 0.001).

CONCLUSIONS

The results of this study showed that this version of the 3IQ-Br has acceptable measurement properties for identifying and differentiating UI symptoms in Brazilian women.

Spanish Questionnaires for the Assessment of Pelvic Floor Dysfunctions in Women: A Systematic Review of the Structural Characteristics and Psychometric Properties

BACKGROUND

Pelvic floor dysfunctions affect a third of the adult female population, including a large number of clinical conditions, which can be evaluated through validated questionnaires that inform us of the status and perception of women both objectively and subjectively. The main objective of this study was to review and explain the topics of the validated questionnaires in Spanish on pelvic floor dysfunctions and to review their psychometric properties.

METHODS

A systematic review was carried out in the PUBMED and WOS databases. The keywords used were in PUBMED: (((((((("Fecal Incontinence" [Mesh]) OR "Urinary Incontinence" [Mesh]) OR "Pelvic Organ Prolapse" [Mesh]) OR "Pelvic Floor Disorders" [Mesh]) OR "Sexual Dysfunction, Physiological" [Mesh]) OR "Pelvic Girdle Pain" [Mesh]) OR "sexual function" [Title/Abstract]) OR "Prolapse" [Title/Abstract]) AND "Surveys and Questionnaires" [Mesh] AND "Validation" [Title/Abstract] combined with the Boolean operators "AND"/"OR". In contrast, in WOS, a segregated search was carried out with each of the terms of pelvic floor dysfunction together with "Validation" and "Surveys and Questionnaires". All articles published up to 19 November 2021 were considered. Methodological quality was assessed with the COSMIN scale.

RESULTS

A total of 687 articles were identified, of which 13 were included. The evaluated questionnaires and the structural characteristics and psychometric properties of each of them were collected.

CONCLUSION

The Spanish versions of the questionnaires show good basic structural and psychometric characteristics for the evaluation of patients with pelvic floor dysfunctions and that they resemble other versions of the same questionnaire published in other languages.

Responsiveness of the Spanish Version of Newcastle Stroke-Specific Quality of Life Measure (NEWSQOL)

OBJECTIVE

To evaluate the responsiveness of the Spanish version of the Newcastle Stroke-specific Quality of Life measure (NEWSQOL) to assess quality of life in Spanish people after suffering a stroke.

DESIGN

A prospective observational study was conducted to assess the responsiveness of the Spanish version of NEWSQOL. The sample contained 128 patients who filled in the questionnaires before and after a physical therapy intervention. The responsiveness was assessed with p-values using the effect size (ES) and the standardized response means (SRMs) of the change. Besides, two other external criteria were used to distinguish patients who improved with the treatment from those who remained stable. This classification was based on one functional independence measure (the Barthel Index) and one disability measure (the modified Rankin Scale).

RESULTS

There was a statistically significant correlation (Spearman's coefficient = p < 0.01) between the domains of the Spanish version of NEWSQOL in relation to the Barthel Index and the modified Rankin Scale. All domains showed between marked-to-mild change responsiveness except sleep and relationships; mobility (ES 0.66 and SRM 0.92) and activities of daily living (ES 0.75 and SRM 0.87) were markedly responsive; communication (ES 0.38 and SRM 0.61) was moderately responsive; and pain, vision, cognition, feelings, emotions and fatigue were mildly responsive (ES 0.21-0.41 and SRM 0.23-0.44).

CONCLUSION

The Spanish version of NEWSQOL shows between marked and mild responsiveness to measure the perception of QoL in post-stroke patients. Therefore, its use can be suitable for evaluation studies, clinical trials and clinical practice.

Postural Sensorimotor Control on Anorectal Pressures and Pelvic Floor Muscle Tone and Strength: Effects of a Single 5P® LOGSURF Session. A Cross-Sectional Preliminary Study

Pelvic floor dysfunction (PFD) is a functional condition present most frequently in women. Despite pelvic floor muscle training being considered by the International Continence Society (ICS) as the first-line treatment in uncomplicated urinary incontinence, other more comprehensive postural methods as 5P^® LOGSURF have emerged. This preliminary cross-sectional study explores the effects of a single 5P^® LOGSURF session on pelvic floor muscle (PFM) tone and strength (MVC), resting anal tone, intrarectal pressure, and deep abdominal muscles activation. Thirty women were included (11 without PFD and 19 with PFD). Primary outcome measures were PFM tone, PFM MVC and resting anal tone and secondary measures outcomes were intrarectal pressure and deep abdominal activation. All outcome measures were collected before, throughout and after a single 30′ 5P^® LOGSURF session. The findings from this study suggest that PFM tone (PFD group: p = 0.09, d = 0.72; non-PFD group: p = 0.003, d = 0.49) and PFM MVC (PFD group: p = 0.016; non-PFD group: p = 0.005) decreased in both groups after a single 5P^® LOGSURF session, with a medium effect size for women with PFD. Contrarily, deep abdominal muscle MVC increased (PFD group: p < 0.001; non-PFD group: p = 0.03). Intrarectal pressure and resting anal tone decreased in both groups throughout the session. These results suggest that 5P^® LOGSURF method may be interesting if is performed by women with mild symptoms of PFD or healthy women to achieve a decrease in PFM tone in women who manifested pain to intracavitary techniques or practices. Further research with higher sample sizes and long-term are necessary for generalizing.

Pelvic floor distress inventory (PFDI)-systematic review of measurement properties

INTRODUCTION AND HYPOTHESIS

The Pelvic Floor Distress Inventory (PFDI) and PFDI-20 have been translated and validated into several languages ​​with different measurement property values ​​and are recommended by the International Consultation on Incontinence (ICI) as grade A for assessing pelvic floor dysfunction. Thus, the aim of the current study was to investigate the measurement properties of the PFDI and PFDI-20.

METHODS

Systematic review conducted in August 2020 through a search performed in PubMed, SCOPUS, WoS, ScienceDirect, CINAHL, and Google Scholar for studies that evaluated the measurement properties of the PFDI and PFDI-20. The data were analyzed according to the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN).

RESULTS

Initially, 2857 studies were found, and 7 studies on PFDI and 25 on PFDI-20 were analyzed. The PFDI presented high quality of evidence for hypothesis testing, moderate for test-retest reliability and responsiveness, and very low quality of evidence for content validity. The PFDI-20 presented high quality of evidence for criterion validity, hypothesis testing, and responsiveness, moderate quality for test-retest reliability and measurement errors, and very low quality of evidence for content validity. It was not possible to rate the quality of evidence of the internal consistency of the PFDI and PFDI-20. No studies assessed the cross-cultural validity.

CONCLUSION

Only the hypothesis testing presented high quality of evidence for the PFDI. Criterion validity, hypothesis testing, and responsiveness presented a high quality of evidence for the PFDI-20. Due to the high degree of recommendation of the PFDI and PFDI-20 given by the ICI, further studies are needed to reevaluate all the measurement properties of these instruments.

Responsiveness of Pelvic Floor Distress Inventory (PFDI-20) and Pelvic Floor Impact Questionnaire (PFIQ-7) after pelvic floor muscle training in women with stress and mixed urinary incontinence

OBJECTIVE

To evaluate the responsiveness of Brazilian-Portuguese version of Pelvic Floor Distress Inventory-20 (PFDI-20) and Pelvic Floor Impact Questionnaire-7 (PFIQ-7) after pelvic floor muscle training (PFMT) in women with stress urinary incontinence (SUI) and mixed urinary incontinence (MUI).

STUDY DESIGN

This is an observational study with 72 women (51.8 ± 11.9SD years) with SUI (n = 33) and MUI (n = 39). Participants answered PFDI-20 and PFIQ-7 before and after PFMT, which consisted of a 12 weeks protocol supervised by a physiotherapist once a week with 30 min of a duration. Wilcoxon test, effect size (ES) and standardized response mean (SRM) were performed on baseline and after three months.

RESULTS

We found a significant reduction in PFDI-20 and PFIQ-7 after PFMT (p < 0.001), except for Pelvic Organ Prolapses Distress Inventory (POPDI-16), Colorectal-Anal Impact Questionnaire (CRAIQ-7) and Pelvic Organ Prolapse Impact Questionnaire (POPIQ-7). The responsiveness of both questionnaires was considered moderate for PFDI-20 (ES = 0.49; SEM = 0.61; p < 0.0001) and PFIQ-7 (ES = 0.51; SEM = 0.52; p < 0.0001).

CONCLUSIONS

PFDI-20 and PFIQ-7 Brazilian Portuguese version presented moderate responsiveness in women with SUI and MUI who performed a PFMT.

Quality of Life in POP: Validity, Reliability and Responsiveness of the Prolapse Quality of Life Questionnaire (P-QoL) in Spanish Women

The Prolapse Quality of Life Questionnaire (P-QoL) is a specific questionnaire created to assess the impact of pelvic organ prolapse on women’s quality of life. The aim of the present study was to cross-culturally adapt and assess the psychometric properties of the P-QoL for Spanish women. The cross-cultural adaptation was conducted by a standardized translation/back-translation method. Psychometric analysis was performed by assessing the validity, reliability, responsiveness and feasibility. A total of 200 Spanish women were recruited and assigned to symptomatic and asymptomatic groups. The Spanish P-QoL version demonstrated good content validity. Convergent validity showed high intercorrelations with the Pelvic Floor Distress Inventory short form and the Pelvic Floor Impact Questionnaire short form. The discriminant validity showed statistically significant differences between the symptomatic and the asymptomatic groups. The internal consistency was high and of acceptable values. The test-retest reliability was shown to be high in all the cases. Regarding responsiveness, the effect size and standardized response mean demonstrated moderate values. The average time for administration was 10 (3) min. The Spanish P-QoL showed considerable support for the appropriate metric properties of validity, reliability, responsiveness and feasibility to evaluate the symptom severity and its impact on the quality of life in Spanish women with urogenital prolapse.

The Female Sexual Function Index: Transculturally Adaptation and Psychometric Validation in Spanish Women

BACKGROUND

The evaluation of sexual function is an important outcome in women who suffer some pelvic floor disorders (PFD). The Female Sexual Function Index (FSFI) is the most widely used questionnaire to evaluate the sexual health in female population. This study presents the adaptation and psychometric validation of the FSFI for Spanish women with PFD.

METHODS

The Spanish version of the FSFI was developed through the forward and backward translation process. The psychometric properties of reliability, validity, responsiveness, and feasibility were conducted in Spanish women with PFD who were assigned to the case or control group (with or without sexual dysfunction respectively).

RESULTS

A total of 323 Spanish women with PFD were recruited. The cross-cultural adaptation of the Spanish FSFI achieved a good semantic, conceptual, idiomatic, and content equivalence. The test-retest reliability was shown to be high in all of the cases. The convergent validity showed high results in the domain intercorrelations between each domain and total FSFI. The discriminant validity showed statistically significant differences between sexual dysfunction and control groups. The responsiveness was shown to be moderate to good in the dimensions and excellent in the total FSFI.

CONCLUSIONS

Spanish FSFI can be used as a reliable, valid, responsive, and feasible instrument for assessing sexual function in women.

Considering Low Health Literacy: How Do the Pelvic Floor Distress Inventory-Short Form 20 and Pelvic Floor Impact Questionnaire-Short Form 7 Measure Up?

OBJECTIVE

The objective of this study was to evaluate the readability and understandability of 2 commonly used pelvic floor disorder questionnaires, Pelvic Floor Distress Inventory-Short Form 20 (PFDI-20) and Pelvic Floor Impact Questionnaire-Short Form 7 (PFIQ-7), in a low health literacy patient population.

METHODS

Flesh-Kincaid, SMOG, Fry, and FORCAST readability assessment tools were used to assign US grade levels to each questionnaire (PFDI-20, PFIQ-7). Two health literacy experts used PEMAT and ELF-Q tools to determine understandability, organization, content, and quality of each form. A focus group of women with low health literacy used Stop Light Coding and a facilitator-prompted discussion to further evaluate understandability and critique the forms.

RESULTS

The PFIQ-7 required higher reading ability compared with PFDI-20 (ninth to 11th vs sixth to eighth mean grade level equivalents). Expert and focus group reviews identified concerns regarding purpose, formatting, and word choice in both forms. Focus group participants recommended assistance with questionnaire completion from clinical staff and gave mean overall ratings of 5.4 (0-10/worst to best) for PFDI-20 and 8.0 for PFIQ-7.

CONCLUSIONS

Knowledge of potential barriers to understanding and completion may improve utilization of and accuracy of patient responses to PFDI-20 and PFIQ-7 in women with low health literacy.

Muscle function of the pelvic floor in healthy, puerperal women with pelvic floor dysfunction

OBJECTIVES

To understand the function of the pelvic floor muscles (PFM) at different ages in healthy women and in puerperal women with pelvic floor dysfunctions (PFD) and to ascertain whether there are differences among them.

MATERIAL AND METHODS

A descriptive cross-sectional study was conducted between June 2014 and September 2016 and included 177 women, 70 of whom had no symptoms of PFD, 53 primiparous mothers in late postpartum and 54 with PFD. The function of the PFM was measured through vaginal palpation (quality of the contraction); manometry (force); dynamometer (tone, strength, and response to stretching), and surface electromyography (neuromuscular activity and resistance).

RESULTS

The healthy women showed superior values for PFM tone, maximum strength, neuromuscular activity and resistance than the puerperal mothers and the women with PFD (P<.01). The puerperal women and those with PFD showed similar functional PFM values (P>.05). The muscle function of the healthy women did not vary significantly with age, except in the case of tone, which was lower in the women older than 46 years (P=.004).

CONCLUSIONS

Age and births decrease the baseline tone of the PFM in healthy women. Therefore, lower strength, resistance and neuromuscular activity appear to be the main difference between the PFM of women with PFD and the PFM of healthy women.
