Gestational diabetes is associated with alteration on pelvic floor muscle activation pattern during pregnancy and postpartum: Prospective cohort using electromyography assessment.

Background and objective: Gestational diabetes mellitus (GDM) is a comorbidity which may cause acute and lifelong disorders to mother and child. Alterations in muscular and connective tissues have been associated with GDM in translation studies, characterizing gestational diabetic myopathy. Pregnancy-specific urinary incontinence and sexual disabilities, disorders that depend on the pelvic floor muscle (PFM) integrity, are also associated with GDM both during and after pregnancy. The aim was to compare PFM activation patterns between GDM and non-GDM women from 24-30 gestational weeks to 18-24 months postpartum during a standard clinical test during gestation and postpartum. Methods: We conducted a prospective three-time-point cohort study from gestation (24-30 weeks-T1, and 36-38 weeks-T2) to 18-24 months postpartum (T3). PFM electromyography was recorded in primigravida or primiparous women with one previous elective c-section with or without the diagnosis of GDM according to the American Diabetes Association criteria. A careful explanation of the muscle anatomy and functionality of the PFM was given to participants before EMG assessment. The outcome measures were PFM activation patterns assessed during pregnancy and postpartum, comparing intra and between groups. PFM activation patterns were assessed by normalized electromyography signal at rest and during 1-second (sec) phasic, 10-sec hold, and 60-sec sustained contractions. Results: Demographic and obstetric data showed homogeneity between groups. The GDM group achieved peak PFM EMG amplitudes similarly to the non-GDM group, but they took longer to return to baseline levels during the ~1-sec contraction (flicks). During 10-sec hold contractions, the GDM group sustained lower levels of PFM activation than the non-GDM group at both 36-38 weeks of gestation and 18-24 months postpartum when compared to the non-GDM group. Conclusion: The results suggest that GDM impaired PFM control mainly on 1-sec flicks and 10-sec hold contraction, which appears to develop during late pregnancy and extends long-term postpartum. This motor behavior may play a role on pelvic floor dysfunctions.

Prevalence and factors associated with pelvic floor dysfunction in university women: a cross-sectional study / Prevalência e fatores associados à disfunção do assoalho pélvico em mulheres universitárias: um estudo transversal

Abstract Introduction Urinary incontinence (UI), fecal inconti-nence (FI), and genito-pelvic pain or penetration disorder (GPPPD) are considered pelvic floor dysfunction (PFD), and are mainly characterized by poor functionality of the pelvic floor muscles. Despite the relevance of these dysfunctions in women's lives, the demand for care is low. Objective To analyze the prevalence of PFD, in university women, and factors associated with PFD. Methods This is a cross-sectional study conducted at São Paulo State University, Marília, SP, Brazil, with undergraduate and/or postgraduate women aged over 18 years. An online questionnaire containing 40 open and multiple-choice questions about PFD was developed by the authors and a Google form was disclosed via social media (Facebook, Instagram) to the participants. The questionnaire was applied between April and July 2020. Results A sample of 707 participants was included. The average age was 22.5 ± 21.0 years old. The most prevalent PFD was GPPPD, reported by 30.7% of women, followed by UI (16.8%) and FI (3.2%). PFD was significant less reported in the Midwest region compared to other regions (p = 0.015) and significantly more prevalent in women who attended public university (p = 0.038), in women with UI, FI, and GPPPD. The association-test showed that attending public university showed association to UI (p < 0.001), FI (p = 0.008) and GPPPD (p = 0.006). In addition, parity showed association with GPPD (p = 0.032) and to attend health courses with UI (p = 0.002). Conclusion PFD is prevalent among university women and GPPPD was the most recurrent, followed by UI and FI. GPPPD was associated with parity and attending a public university. UI was associated with attending public university and health courses. FI was associated with attending a public university.

Resumo Introdução A incontinência urinária (IU), a incontinência fecal (IF) e a dor genitopélvica ou distúrbio de penetração (DGDP) são considerados disfunções do assoalho pélvico (DAP) e caracterizam-se principalmente pela má funcionalidade dos músculos do assoalho pélvico. Apesar da relevância dessas disfunções na vida das mulheres, a demanda por atendimento é baixa. Objetivo Analisar a prevalência das DAP em mulheres universitárias e fatores associados à DAP. Métodos Trata-se de um estudo transversal realizado na Universidade Estadual Paulista, Marília, SP, Brasil, com graduandas e/ou pós-graduandas maiores de 18 anos. Um questionário online contendo 40 questões abertas e de múltipla escolha sobre DAP foi desenvolvido pelos autores e um formulário do Google foi divulgado via mídia social (Facebook, Instagram) às participantes. O questionário foi aplicado entre abril e julho de 2020. Resultados Uma amostra de 707 participantes foi incluída. A média de idade foi de 22,5 ± 21 anos.

Knowledge of pelvic floor disorders in young women: a cross-sectional study / Conhecimento dos distúrbios do assoalho pélvico em mulheres jovens: um estudo transversal

Abstract Introduction: Young women's knowledge about pelvic floor function and dysfunction are poor. Objective: To identify the level of knowledge of young women about pelvic floor muscles (PFM) anatomy and function, pelvic floor muscle dysfunction (PFMD), pelvic organ prolapse (POP), and sexual dysfunction (SD). Methods: This is a cross-sectional study. Two hundred forty-two (242) young women from first to the third year of high school from ten public schools, in geographically disparate areas of a Brazilian county serving economic minority student populations, participated in the study. Data analysis was performed using SPSS 20.0 (SPSS Inc., Chicago, IL). The categorical data were expressed as absolute and relative frequency. Results: Only 28% of the young women knew PFM, and 26% answered to be able to contract these muscles. The prevalence of urinary incontinence was 16%, while 5% reported fecal incontinence. The previous knowledge about POP was similar between bladder and uterus prolapse, 34% and 40%, respectively. SD was known by 48% of the young women. Seventy-seven young women (31.8%) declared to have had sexual intercourse. Ten percent declared difficulties to allow vaginal penetration, and 48% of those who were able to have penetration declared that they experienced pain and discomfort. Conclusion: Young women have little knowledge about the PFM anatomy and function, PFMD, POP, and SD. In addition, they have complaints related to sexual practice, such as difficulty during vaginal penetration and pain.

Resumo Introdução: O conhecimento de mulheres jovens sobre a função e disfunção do assoalho pélvico é insuficiente.

Influence of transducer orientation on shear wave velocity measurements of the iliotibial band.

Tissue anisotropy influences estimation of mechanical properties of connective tissues, such as the iliotibial band (ITB). This study investigated the influence of ultrasound transducer rotation and tilt on shear wave velocity (SWV, an index of stiffness) measurements of the ITB and the intra-rater repeatability of SWV measurements in the longitudinal direction. SWV was measured unilaterally (dominant limb) using ultrasound shear wave elastography in the middle region of the ITB in supine at rest (20-25° knee flexion) in ten healthy volunteers (4 females). A 3-dimensional video system provided real-time feedback of probe orientation with respect to the thigh. Measurements were made at 10° increments of probe rotation, from longitudinal to transverse alignment relative to the approximate direction of ITB fibres, and 5-10° tilts about the longitudinal and sideways axes of the transducer. One-way repeated measures ANOVA compared SWV between angles and tilts. Intraclass correlation coefficients (ICCs) and standard error of measurement (SEM) were used to calculate repeatability for two to five (longitudinal only) repetitions. SWV was greatest when the transducer was aligned to ITB fibres (longitudinal: 10.5 ± 1.7 m/s) and lowest when perpendicular (transverse: 5.8 ± 2.4 m/s). Compared to longitudinal alignment, SWV decreased significantly (p < 0.01) when the transducer was rotated 20° or more. Tilted measurements did not differ between angles. Intra-rater repeatability was excellent with the average of two measurements (ICC = 0.99, 95% CI 0.95, 0.99; SEM = 0.31 m/s). These findings show that SWV changes with orientation relative to fibre direction. Transducer orientation requires careful control to ensure comparable measures.

Muscle recruitment and co-contraction when walking in young women with chronic lumbar pain / Recrutamento e cocontração muscular durante a marcha em mulheres jovens com dor lombar crônica / Reclutamiento y co-contracción muscular durante la marcha en mujeres jóvenes con dolor lombar crónica

Abstract Introduction: The lumbar pain is the main musculoskeletal complaint reported by the active population, and it prevents daily activities such as walking. Objective: To assess muscle recruitment and the co-contraction of the trunk muscles during different walking speed in individuals with and without chronic lumbar pain. Method: Thirty-four sedentary young women attended the study, in which 18 belonged to the lumbar pain team (LPT) and 16 to the team without lumbar pain (WLP). We assessed the electromyography activity of the internal oblique (IO) local muscle and lumbar multifidus (MUL), and global external oblique (EO), abdominal rectus (AR) and lumbar iliocostalis (LIC), during walking. The electromyography analysis was performed from the average of the linear envelope value, normalized by the peak of muscle activation. The muscle co-contraction (IO/MUL, EO/LIC, AR/LIC, IO/EO, and the abdominal/paravertebral muscle groups) was calculated with the Falconer and Winter formula. The Shapiro-Wilk test, Multivariate Analysis, mixed Variance Analyses with Bonferroni post-hoc, and Pearson (p < 0.05) correlation coefficient were made by the statistical analysis. Results: In the WLP we could notice that the higher the speed, the higher the MUL activation. The co-contraction data demonstrated that IO/MUL muscles activate 20% more in the LPT, during the preferred speed; however, in the WLP, the results showed that the higher the walking speed, the higher the EO/LIC (21.8%) and IO/MUL (17.8%) muscles activation. Conclusion: The recruitment of local muscles doesn't differ among the evaluated groups and conditions; however, in WLP, the higher the MUL muscle action, the higher the walking speed.

Resumo Introdução: A dor lombar (DL) é a principal queixa musculoesquelética relatada na população ativa e incapacita atividades do cotidiano, como a marcha. Objetivo: Avaliar o recrutamento e co-contração dos músculos do tronco durante diferentes velocidades de marcha em indivíduos com e sem DL crônica. Método: Participaram 34 mulheres jovens, sedentárias, 18 compuseram o grupo DL (GDL) e 16 o grupo sem DL (GC). Foi avaliada a atividade eletromiográfica dos músculos locais oblíquo interno (OI) e multífido lombar (MUL), e globais oblíquo externo (OE), reto abdominal (RA) e iliocostal lombar (ICL), durante a marcha. A análise eletromiográfica foi realizada a partir da média do valor de envelope linear, normalizada pelo pico de ativação muscular. A co-contração muscular (OI/MUL, OE/ICL, RA/ICL, OI/OE e os grupos musculares abdominais/ paravertebrais) foi calculada com a fórmula de Falconer e Winter. A análise estatística foi feita por meio do teste Shapiro-Wilk, Análise Multivariada, Análise de Variância mista com pos-hoc bonferroni e coeficiente de correlação de Pearson (p < 0,05). Resultados: No GC podemos perceber que, quanto maior a velocidade, maior a ativação do MUL. Os dados de co-contração demonstraram que os músculos OI/MUL ativam 20% a mais no GDL, durante a velocidade de preferência, no GC, os resultados mostram que quanto maior a velocidade de marcha, maior a ativação dos músculos OE/ICL (21,8%) e OI/MUL (17,8%). Conclusão: O recrutamento dos músculos não difere entre os grupos e condições, contudo foi observado no GC que quanto maior a ação do músculo MUL maior é a velocidade de marcha.

Evolution of female urinary continence after physical therapy and associated factors.

BACKGROUND: Urinary incontinence (UI) is defined as any involuntary loss of urine that can influence the quality of life, personal hygiene and social interaction. The types of UI that most affect women are stress urinary incontinence, urge incontinence and mixed urinary incontinence. There are several risk factors that result in specific treatments. We aimed to investigate the evolution of female urinary continence after physical therapy intervention and its associated factors. METHOD: A retrospective cross-sectional study was conducted with 71 participants who were discharged from physiotherapy sector from August 2006 to April 2012 and met the inclusion criteria. RESULTS: Among the studied variables, the number of sessions and completion of home pelvic floor exercises showed a significant association. The urinary continence appeared in 43.7% of the cases, and factors, performance of home exercises, and number of sessions showed a significant association. CONCLUSION: The number of sessions and completion of home pelvic floor exercises showed a significant relationship with each other.
