Techniques for Registration of Myoelectric Activity of Women's Pelvic Floor Muscles: A Scoping Review.

INTRODUCTION AND HYPOTHESIS: Surface electromyography is commonly applied to measure the electrophysiological activity of the neuromuscular system. However, there is no consensus regarding the best protocol to assess pelvic floor muscles. METHODS: A scoping literature review was carried out in six databases, using MeSH descriptors. It included studies with electromyographic assessment in adult women presenting or not with pelvic floor dysfunction. The results were presented in categories to contribute to the development of a protocol considering the most used parameters for non-invasive assessment of myoelectric activity of pelvic floor muscles. RESULTS: A total of 1,074 articles were identified, and 146 studies were selected for analysis. The intravaginal probe was used in 80.8% of the studies, the bipolar sensor with metallic plates placed on both sides of the vagina was the most frequent (71.3%), with a reference electrode positioned on the anterior superior iliac spine (33.5%). The supine position with hip and knee flexed (45.2%) was the most frequent position used. Of the studies, 44.5% normalized the data by maximum voluntary contraction (MVC) whereas 44.5% performed an average of 3 MVCs. CONCLUSIONS: The most frequently used protocol for the pelvic floor is the bipolar intracavitary probe with metal plates positioned at 3-9 o'clock and introduced distally to the vaginal introitus with the volunteer in the supine position and the hip and knee flexed with the reference placed on the anterior-superior iliac spine.

Effectiveness of group aerobic and/or resistance exercise programs associated with pelvic floor muscle training during prenatal care for the prevention and treatment of urinary incontinence: A systematic review.

AIM: To evaluate the effectiveness of aerobic and/or resistance group exercise programs associated with pelvic floor muscle training (PFMT) during prenatal care for the prevention and treatment of urinary incontinence (UI) using the best level of evidence. METHODS: A search was carried out in the MEDLINE/PubMed, LILACS, PEDro, CENTRAL, and SCOPUS databases, without restrictions. The terms "urinary incontinence" and "pregnant woman" were used. Randomized and quasi-randomized clinical trials were included using aerobic and/or resistance exercise programs plus PFMT as an intervention compared to usual care. The Cochrane tool (RoB 2.0) and GRADE were used to assess risk of bias and certainty of evidence, respectively. Quantitative analysis was assessed by meta-analyses. RESULTS: Five publications were included. There was a reduction in the reports of UI postintervention at 16 weeks (RR: 0.83; 95% CI: 0.74-0.93, one study, 762 women, random effects: p = 0.002) and after 3 months (RR: 0.76; 95% CI: 0.60-0.95, one study, 722 women, random effects: p = 0.02), based on moderate certainty of evidence and improvement in UI-specific quality of life (MD: -2.42; 95% CI: -3.32 to -1.52, one study, 151 women, random effects: p < 0.00001), based on low quality of evidence. Other results showed no difference between the postintervention groups, with low and very low evidence. CONCLUSION: There is moderate evidence that the aerobic and/or resistance exercise program associated with PFMT compared to usual care can reduce postintervention UI, as well as 3 months postintervention, and that it can improve UI-specific quality of life, but with low-evidence certainty.

Active pelvic movements on a Swiss ball reduced labour duration, pain, fatigue and anxiety in parturient women: a randomised trial.

QUESTION: How much do active pelvic movements on a Swiss ball during labour affect maternal and neonatal outcomes? METHOD: A randomised trial with concealed allocation, blinded assessors and intention-to-treat analysis. PARTICIPANTS: Two-hundred parturient women. INTERVENTION: The experimental group performed pelvic anteversion and retroversion, lateral pelvic tilts and circular hip movements according to individual obstetric evaluation (foetal station and position, cervical dilatation and the presence of early pushing urge) on a Swiss ball. The control group received usual care. Both groups were permitted to walk and shower. OUTCOME MEASURES: The primary outcome was the duration of the first stage of labour. The secondary outcomes were the duration of the second stage of labour, pain intensity, delivery mode, medication use, local swelling, fatigue, anxiety, satisfaction and neonatal outcomes. RESULTS: The experimental intervention reduced the duration of labour by 179 minutes (95% CI 146 to 213) in stage one and 19 minutes (95% CI 13 to 25) in stage two. It decreased pain by approximately 2 points (95% CI 2 to 2) on a 0-to-10 scale at 30, 60 and 90 minutes. It reduced the risk of a caesarean section (ARR 0.14, 95% CI 0.03 to 0.25; NNT 7, 95% CI 4 to 32) and vulvar swelling (ARR 0.11, 95% CI 0.03 to 0.19; NNT 9, 95% CI 5 to 31). It reduced fatigue by 18 points (95% CI 16 to 21) on a 15-to-75-point scale and anxiety by 9 points (95% CI 8 to 11) on an 18-to-72-point scale. Other effects were negligible or unclear. CONCLUSION: Active pelvic movements on a Swiss ball during labour reduced the duration of labour, pain intensity, and maternal fatigue and anxiety; they also lowered the risk of caesarean section and vulvar swelling. Several effects exceeded the smallest worthwhile effect. REGISTRATION: NCT04124835.

Cochlear radiation dose and hearing loss in patients with vestibular schwannoma undergoing radiosurgery: systematic review

Abstract Objectives: To determine the cut-off point of the cochlear radiation dose as a risk factor for hearing loss in patients with vestibular schwannoma treated with radiosurgery. Methods: A systematic review of the literature was performed without language or publication year restrictions in the MEDLINE/PubMed, EMBASE, Web of Science, LILACS/VHL and Cochrane Library databases. Studies that met the following criteria were included: 1) population: adults of both sexes who underwent radiosurgery for vestibular schwannoma treatment; 2) exposure: cochlear radiation; 3) outcome: hearing loss; 4) type of study: cohort. Two independent reviewers conducted the entire review process. The registration number in PROSPERO was CRD42020206128. Results: From the 333 articles identified in the searches, seven were included after applying the eligibility criteria. There was no standardization as to how to measure exposure or outcome in the included studies, and most studies did not present sufficient data to enable meta-analysis. Conclusion: It was not possible to determine a cut-off point for high cochlear dose that could be considered a risk factor for hearing loss.

Effectiveness of the aquatic physical therapy exercises to improve balance, gait, quality of life and reduce fall-related outcomes in healthy community-dwelling older adults: A systematic review and meta-analysis.

BACKGROUND: Opting to use aquatic or land-based physical therapy exercises to improve balance, gait, quality of life and reduce fall-related outcomes in community-dwelling older adults (CDOAs) is still a questionable clinical decision for physiotherapists. OBJECTIVE: Assess the quality of evidence from randomized or quasi-randomized controlled trials that used aquatic physical therapy exercises to improve balance, gait, quality of life and reduce fall-related outcomes in CDOAs. METHODS: Articles were surveyed in the following databases: MEDLINE/PubMed, EMBASE, SCOPUS, LILACS, Web of Science, CENTRAL (Cochrane Central Register of Controlled Trials), PEDro, CINAHL, SciELO and Google Scholar, published in any language, up to July 31, 2023. Two independent reviewers extracted the data and assessed evidence quality. The risk of bias of the trials was evaluated by the Cochrane tool and evidence quality by GRADE approach. Review Manager software was used to conduct the meta-analyses. RESULTS: 3007 articles were identified in the searches, remaining 33 studies to be read in full, with 11 trials being eligible for this systematic review. The trials included presented low evidence quality for the balance, gait, quality of life and fear of falling. Land-based and aquatic physical therapy exercises improved the outcomes analyzed; however, aquatic physical therapy exercises were more effective in improving balance, gait, quality of life and reducing fear of falling in CDOAs. The meta-analysis showed that engaging in aquatic physical therapy exercises increases the functional reach, through of the anterior displacement of the center of pressure of CDOAs by 6.36cm, compared to land-based physical therapy exercises, assessed by the Functional Reach test: [CI:5.22 to 7.50], (p<0.00001), presenting low quality evidence. CONCLUSIONS: Aquatic physical therapy exercises are more effective than their land-based counterparts in enhancing balance, gait, quality of life and reducing the fear of falling in CDOAs. However, due to methodological limitations of the trials, this clinical decision remains inconclusive. It is suggested that new trials be conducted with greater methodological rigor, in order to provide high-quality evidence on the use of the aquatic physical therapy exercises to improve the outcomes analyzed in CDOAs.

Use of Virtual Reality-Based Games to Improve Balance and Gait of Children and Adolescents with Sensorineural Hearing Loss: A Systematic Review and Meta-Analysis.

BACKGROUND: Children and adolescents with sensorineural hearing loss (SNHL) often experience motor skill disturbances, particularly in balance and gait, due to potential vestibular dysfunctions resulting from inner ear damage. Consequently, several studies have proposed the use of virtual reality-based games as a technological resource for therapeutic purposes, aiming to improve the balance and gait of this population. OBJECTIVE: The objective of this systematic review is to evaluate the quality of evidence derived from randomized or quasi-randomized controlled trials that employed virtual reality-based games to enhance the balance and/or gait of children and adolescents with SNHL. METHODS: A comprehensive search was conducted across nine databases, encompassing articles published in any language until 1 July 2023. The following inclusion criteria were applied: randomized or quasi-randomized controlled trials involving volunteers from both groups with a clinical diagnosis of bilateral SNHL, aged 6-19 years, devoid of physical, cognitive, or neurological deficits other than vestibular dysfunction, and utilizing virtual reality-based games as an intervention to improve balance and/or gait outcomes. RESULTS: Initially, a total of 5984 articles were identified through the searches. Following the removal of duplicates and screening of titles and abstracts, eight studies remained for full reading, out of which three trials met the eligibility criteria for this systematic review. The included trials exhibited a very low quality of evidence concerning the balance outcome, and none of the trials evaluated gait. The meta-analysis did not reveal significant differences in balance improvement between the use of traditional balance exercises and virtual reality-based games for adolescents with SNHL (effect size: -0.48; [CI: -1.54 to 0.57]; p = 0.37; I2 = 0%). CONCLUSION: Virtual reality-based games show promise as a potential technology to be included among the therapeutic options for rehabilitating the balance of children and adolescents with SNHL. However, given the methodological limitations of the trials and the overall low quality of evidence currently available on this topic, caution should be exercised when interpreting the results of the trials analyzed in this systematic review.

Eficácia E Custo-Utilidade De Intervenções Para O Tratamento Da Enurese Em Crianças E Adolescentes Sob A Perspectiva Do Sistema Único De Saúde Brasileiro: Effectiveness and Cost-Utility of Interventions for Enuresis Treatment in Children and Adolescents From the Brazilian Single Health System Perspective.

OBJECTIVES: This study aimed to estimate the cost-utility of effective interventions for enuresis treatment in children and adolescents and to calculate the incremental cost-utility ratio from the perspective of the Brazilian Unified Health System in a 1-year time horizon. METHODS: The economic analysis is in 7 stages: (1) survey of evidence of treatments for enuresis, (2) performing the network meta-analysis, (3) estimation of the probability of cure, (4) cost-utility analysis, (5) model sensitivity analysis, (6) analysis of acceptability of interventions by acceptability curve, and (7) monitoring the technological horizon. RESULTS: The association between desmopressin and oxybutynin is the therapeutic strategy with the highest probability of success in the treatment of enuresis in children and adolescents compared with placebo (relative risk [RR] 2.88; 95% confidence interval [CI] 1.65-5.04), followed by the combination therapy between desmopressin and tolterodine (RR 2.13; 95% CI 1.13-4.02), alarm (RR 1.59; 95% CI 1.14-2.23), and neurostimulation (RR 1.43; 95% CI 1.04-1.96). Combination therapy between desmopressin and tolterodine was the only 1 considered not to be cost-effective. Neurostimulation, alarm therapy, and therapy had the respective incremental cost-utility ratio values: R$5931.68, R$7982.92, and R$29 050.56/quality-adjusted life-years. CONCLUSION: Among the therapies that are on the borderline of efficiency, the combined therapy between desmopressin and oxybutynin presents the greatest incremental benefit at an incremental cost that is still feasible, given that it does not exceed the reference value of the cost-effectiveness threshold established in Brazil.

Analysis of the Measurement Properties of the Female Sexual Function Index 6-item Version (FSFI-6) in a Postpartum Brazilian Population.

OBJECTIVE: We evaluated internal consistency, test-retest reliability, and criterion validity of the Brazilian Portuguese version of the Female Sexual Function Index 6-item Version (FSFI-6) for postpartum women. METHODS: Therefore, questionnaires were applied to 100 sexually active women in the postpartum period. The Cronbach α coefficient was used to evaluate the internal consistency. Test-retest reliability was analyzed by Kappa for each item of the questionnaire and by the Wilcoxon parametric test, comparing the total scores of each evaluation. For the assessment of criterion validity, the FSFI was used as the gold standard and the receiver operating characteristic (ROC) curve was constructed. Statistical analysis was performed using IBM SPSS Statistics for Windows, version 21.0 (IBM Corp., Armonk, NY, USA). It was found that the internal consistency of the FSFI-6 questionnaire was considerably high (0.839). RESULTS: The test-retest reliability results were satisfactory. It can also be stated that the FSFI-6 questionnaire presented excellent discriminant validity (area under the curve [AUC] = 0.926). Women may be considered as having sexual dysfunction if the overall FSFI-6 score is < 21, with 85.5% sensitivity, 82.2% specificity, positive likelihood ratio of 4.81 and negative likelihood ratio of 0.18. CONCLUSION: We conclude that the Brazilian Portuguese version of FSFI-6 is valid for use in postpartum women.

Assessment of responsiveness and minimum important difference of the Maternal perception of Childbirth Fatigue Questionnaire (MCFQ) / Avaliação da responsividade e diferença mínima importante do Questionário de percepção Materna de Fadiga no trabalho de Parto (QMFP)

INTRODUCTION: The assessment of responsiveness and the Minimum Clinically Important Difference (MCID) is the basis for validating the Maternal perception of Childbirth Fatigue Questionnaire (MCFQ). OBJECTIVE: To assess the responsiveness and determine the value of the MCID for the MCFQ. METHODS: This is an observational study, conducted at HC-UFPE with 50 parturients in active labor. The MCFQ was applied in two moments: in the initial evaluation (EV1), performed at the beginning of labor between 4-6 cm of uterine dilation, and final (EV2), six hours after the first evaluation. Responsiveness was determined by calculating the effect size (ES), and standardized response mean (SRM), considering that values of 0.2, 0.5, and 0.8 points represent respectively small, moderate, or large values of responsiveness. The ability to detect change through the questionnaire was also assessed by the t-test. The level of significance adopted for this analysis was p less than 0.05. The MCID was verified based on the calculation of the standard error of measurement (SEM) index. RESULTS: The MCFQ showed values of 0.4 and 0.6 for ES and SEM respectively and a p-value <0.001, thus showing a good capacity for change. The value of the MCID for this population was seven points. CONCLUSION: MCFQ presents a potentially significant change with a value of the MCID of seven points after six hours of active labor.

INTRODUÇÃO: A avaliação da responsividade e da Diferença Mínima Importante (DMI) é fundamentação para validação do Questionário de percepção Materna de Fadiga no Trabalho de Parto (QMFP). OBJETIVO: Avaliar a responsividade e determinar o valor da DMI para o QMFP. MÉTODOS: Trata-se de um estudo observacional, realizado no HC-UFPE com 50 parturientes em fase ativa do trabalho de parto. O QMFP foi aplicado em dois momentos: na avaliação inicial (AV1), realizada no início do trabalho de parto entre 4-6 centímetro de dilatação uterina, e final (AV2), após seis horas da primeira avaliação. A responsividade foi determinada pelo cálculo do effect size (ES), standardized response mean (SRM), considerando que valores de 0,2, 0,5 e 0,8 pontos representam respectivamente um pequeno, moderado ou grande valor de responsividade. A capacidade de detectar mudança pelo questionário também foi avaliada pelo test t. O nível de significância adotado para essa análise foi p menor que 0,05. A DMI foi verificada com base no cálculo do índice standard error of measurement (SEM). RESULTADOS: O QMFP apresentou valores de 0,4 e 0,6 de ES e SEM respectivamente e valor de p<0,001, logo apresenta uma boa capacidade de mudança. O valor da DMI para esta população foi de sete pontos. CONCLUSÃO: O QMFP apresenta uma mudança potencialmente significativa com um valor da DMI de sete pontos após seis horas de trabalho de parto ativo.

Electromyographic analysis of pelvic floor muscles during the execution of pelvic patterns of proprioceptive neuromuscular facilitation-concept: An observational study.

OBJECTIVE: To assess the effect of pelvic patterns of proprioceptive neuromuscular facilitation (PNF-concept) on pelvic floor muscles (PFM) recruitment, as well as the electromyographic activity of muscles synergic to the pelvic floor in healthy women. METHODS: Observational study conducted with 31 women aged between 18 and 35 years, with mean age of 23.3 ± 3.2 (22.1-24.4). PFM activity was monitored by surface electromyography during the combination of isotonics technique of four pelvic patterns of PNF-concept (i.e., anterior elevation, posterior depression, anterior depression, and posterior elevation). The electromyographic signal was analyzed using root mean square amplitude. Two-way repeated measures analysis of variance was performed to analyze differences in PFM activity between types of contraction (i.e., concentric, isometric, and eccentric) and the four pelvic patterns. RESULTS: PFM activity did not differ among the four pelvic pattens. However, PFM activity was significantly different between the combination of isotonics technique and baseline, F(1.6, 48.2) = 71.5; p < 0.000, with a large effect size (partial ƞ² = 0.705). Concentric (22.4 µV ± 1.1), isometric (17.3 µV ± 0.6), and eccentric (15 µV ± 0.5) contractions of combination of isotonics technique increased PFM activity compared with baseline (10.8 µV ± 0.4) in all pelvic patterns. By analyzing the electromyographic activity of the muscles synergistic to the pelvic floor, there is effect of the interaction of the type of contraction, the pelvic pattern of the PNF concept, and the synergistic muscles on the myoelectric activity of the external anal sphincter, F(3.2, 96.5) = 5.6; p < 0.000, with a large magnitude of effect (partial ƞ² = 0.15). In the anterior elevation pattern, the muscles synergistic to the pelvic floor present synergy in phase with the PFM, and in the posterior patterns there was a decrease in the activity level of all synergistic muscles, without changing the activity level of the PFM. CONCLUSION: PFM activity did not differ among the four pelvic patterns of PNF-concept. Nonetheless, the combination of isotonics technique showed a significant effect on PFM compared with baseline, with greater PFM activity during concentric contraction. Pelvic patterns of PNF-concept may be used to increase PFM recruitment in young healthy women.

What do cochrane systematic reviews say about interventions for enuresis in children and adolescents? An overview of systematic reviews.

OBJECTIVE: To conduct an overview of Cochrane systematic reviews about treatment alternatives for children and/or adolescents with enuresis. SOURCES: An overview of Cochrane systematic reviews about interventions for enuresis in children/adolescents was developed between September/2021 and December/2021. The protocol was registered on PROSPERO and the search was conducted only in the Cochrane Library database without any restriction. Reviews involving any type of intervention for the treatment of enuresis in children/adolescents were included. The risk of bias was assessed using Risk of Bias in Systematic Reviews (ROBIS) and the quality of reviews was assessed using A Measurement Tool to Assess Systematic Reviews (AMSTAR-2). SUMMARY OF THE FINDINGS: Seven systematic reviews were identified. Based on the ROBIS assessment, all reviews were classified as low risk of bias. According to the AMSTAR-2 assessment, the three oldest systematic reviews were rated as critically low quality, one review was moderate quality, and the three most recent systematic reviews were rated as high quality. No difference was shown between alarm and desmopressin for a complete response to therapy after treatment (RR = 1.30; 95%CI: 0.92 to 1.84), but alarm use is related to a lower risk of adverse events (RR = 0.38; 95%CI: 0.20 to 0.71). There is a moderate certainty that the association between imipramine and oxybutynin is better than placebo to reduce the risk of children who do not achieve 14 consecutive dry nights after treatment (RR = 0.43; 95%CI: 0.23 to 0.78). CONCLUSIONS: There is no difference between alarm and desmopressin for enuresis treatment. However, alarm therapy had fewer adverse events than desmopressin. Moreover, combination therapy between imipramine and oxybutynin is better than placebo.

Vocalization during the second stage of labor to prevent perineal trauma: A randomized controlled trial.

BACKGROUND AND PURPOSE: Most women suffer some degree of perineal trauma during vaginal delivery. Second stage management strategies, including vocalization, to protect the perineum have been investigated. OBJECTIVE: To compare the frequency and degree of perineal trauma at vaginal delivery, with and without use of the vocalization maneuver during the second stage of labor. MATERIALS AND METHODS: This is an open-label, randomized controlled trial. We conducted the study at the Center for Normal Deliveries of IMIP. We included low-risk women without prior cesarean deliveries. Women who met the inclusion criteria and signed the informed consent form were randomized to one of two groups: Group A (experimental) and Group B (control). A physical therapist encouraged women in Group A to maintain an open glottis during pushing and to emit sounds when exhaling (vocalization). Women in Group B underwent routine humanized vaginal deliveries. The outcomes of the study were perineal integrity and degree of perineal laceration. These were measured by the study team immediately after completion of the third stage of labor. RESULTS: Women in Group A tended to have less severe perineal tear (less second and third degree lacerations) and smaller lacerations than women in group B. The vocalization maneuver reduced the risk of a perineal tear greater than 2 cm by 68% (NNT 2.2). There was no difference in other outcomes. CONCLUSION: Encouraging women to follow a vocalization protocol coached by a physical therapist during the second stage of labor can be a helpful labor assistance technique, since this study showed that vocalization is associated with less extensive perineal tears. CLINICAL TRIAL REGISTRATION: This study was registered on ClinicalTrials.gov (www. CLINICALTRIAL: gov) registration number: NCT03605615.

Prevalence and factors associated with urinary incontinence in female crossfitters: A cross-sectional study.

OBJECTIVE: To determine the prevalence and factors associated with urinary incontinence (UI) in female crossfitters. METHODS: This is a cross-sectional study. Data were collected using assessment forms: Knowledge, Attitude and Practice survey for young female athletes; Incontinence Severity Index; and International Consultation on Incontinence Questionnaire for UI. Descriptive analysis was conducted to obtain absolute and relative frequencies, means and 95% confidence intervals (95% CI). Multivariate analysis was carried out to determine the association between UI and sociodemographic, gynecological-obstetric, and anthropometric variables, associated morbidities, previous history and physical activity. RESULTS: Prevalence of UI, in the 189 included volunteers, was 38.6% and the most frequent type was stress UI (69.9%). A total of 72.6% of incontinent women reported urine loss during CrossFit training. Knowledge (53.4%) and attitude (86.2%) regarding UI were generally adequate, while prevention, management and treatment were inadequate (96.3%). The predominant characteristics of UI were frequency of once a week or less (74.0%), in small amounts (86.3%), mild intensity (57.5%) and slight impact on quality of life (64.3%). In multivariate analysis, no variable was significantly associated with UI. CONCLUSIONS: The prevalence of UI in female crossfitters was 38.6%. The factors investigated did not contribute to the development of UI.

Effectiveness of the peanut ball use for women with epidural analgesia in labour: a systematic review and meta-analysis.

This meta-analysis aimed to evaluate, using the best level of evidence, the possible benefits and advantages of using peanut ball (PB) in women with an epidural during labour on the maternal and neonatal outcomes. This research was conducted using MEDLINE/PubMed, Embase, LILACS, CINAHL, CENTRAL, PEDro, Web of Science and SCOPUS databases, with no period or language restrictions. The terms 'labor' and 'peanut ball' were used. Clinical trials (randomised and non-randomised) were included when comparing a group of parturients using PB with a control group under usual care. Randomised clinical trials (RCTs) or quasi-randomised were eligible for this systematic review. Two reviewers independently screened studies, extracted data and assessed the quality of evidence which was evaluated by the GRADE system. Quantitative analysis through meta-analysis was also applied whenever possible. In this updated review, we included four studies with a total of 818 women in labour after the use of pharmacological analgesia. Our GRADE ratings of evidence ranged from high to low quality. Overall, the included studies varied in their risk of bias, in which most were considered with some concerns. There is high evidence that the use of PB after epidural analgesia reduces the duration of the first period of labour by 87 minutes and moderate evidence that it increases the chance of vaginal delivery 11%. However, there is no evidence about other maternal and neonatal outcomes.Impact StatementWhat is already known on this subject? The peanut ball (PB) is used after the use of pharmacological analgesia, as it favours the opening of the pelvic canal and helps women to adopt more comfortable postures, but its real effects are not clear.What do the results of this study add? Our results suggest that using the PB reduces the duration of the first period of labour after an epidural and increases the chance of a vaginal birth.What are the implications of these findings for clinical practice and/or further research? These findings recommend the use of a PB after an epidural and further research with women without the use of pharmacological analgesia.

Efficacy of spontaneous pushing with pursed lips breathing compared with directed pushing in maternal and neonatal outcomes.

This is a quasi-randomised clinical trial, with 62 low-risk pregnant women in the second stage of labour. They were randomly allocated in control (CG) (n = 31) and intervention (IG) (n = 31) groups. The IG performed spontaneous pushing with pursed lips breathing while the CG was oriented to perform directed pushing associated with Valsalva Manoeuvre (VM). There was no difference between the groups regarding the occurrence of episiotomy (RR 1,1; 95%IC 1,0 to 1,2). However, there was a decrease in the duration of the maternal pushing by 3.2 min (MD 3,2; 95%CI 1,4 to 5,1) and a difference in maternal anxiety (Md (IQR) IG 46 (35-52), CG 51 (44-56) p:0,049), both favouring the IG. Spontaneous pushing was effective in reducing the duration of the pushing and showed a difference in maternal anxiety but did not decrease the maternal and neonatal outcomes. Brazilian Clinical Trials Registry (ReBEC) under the identifier: RBR-556d22IMPACT STATEMENTWhat is already known on the subject? Spontaneous pushing reduces the duration of pushing time when compared to directed pushing with VM but has no effect on other maternal and neonatal outcomes, based on a low quality of evidence.What do the results of this study add? No subject has been published on the subject. Our results suggest that the use spontaneous pushing with pursed lips breathing reduces the duration of the pushing by 3.2 min, also showing a difference in maternal anxiety. This result may indicate its use for emotional control when compared to the directed pushing.What are the implications of these findings for clinical practice and/or further research? These findings may signal an attitude in decision-making about guiding the breathing pattern in the expulsive stage.

Repercussions of the Degrees of Hearing Loss and Vestibular Dysfunction on the Static Balance of Children With Sensorineural Hearing Loss.

OBJECTIVE: The purpose of this study was to assess the static balance of children with sensorineural hearing loss (SNHL) according to the degrees of SNHL and the function of the vestibular system. METHODS: This cross-sectional study was conducted in public schools located in Caruaru, Pernambuco state, Brazil, with 130 children (65 with normal hearing and 65 with SNHL as documented by air and bone conduction audiometry) of both sexes between 7 and 11 years old. Static balance was assessed by a stabilometric analysis using a force platform consisting of the circular area of center-of-pressure displacement of the children evaluated in 3 positions: bipedal support with feet together and parallel (PF), tandem feet (TF), and 1 foot (OF), carried out under 2 sensory conditions each, with eyes open and eyes closed. After balance assessments, the children with SNHL received examinations of auditory and vestibular functions-through audiometry and computerized vectoelectronystagmography, respectively-to compose the groups according to degrees of SNHL and vestibular function. RESULTS: The children with severe and profound SNHL demonstrated more static balance instabilities than the children with normal hearing in 5 positions assessed with eyes open (PF, TF, and OF) and eyes closed (PF and TF). The same phenomenon occurred in children with SNHL and associated vestibular dysfunction in all of the positions assessed with eyes open and eyes closed (PF, TF, and OF). CONCLUSION: The larger the degree of SNHL, the greater the balance instability of the children. The children with SNHL and associated vestibular dysfunction showed the highest balance instabilities in this study. IMPACT: Children with larger degrees of SNHL and associated vestibular dysfunction might require prolonged periods to rehabilitate their balance.

Assessment of the strength and electrical activity of the pelvic floor muscles of male-to-female transgender patients submitted to gender-affirming surgery: A case series.

AIMS: To assess the strength and electrical activity of the pelvic floor muscles (PFMs) of male-to-female transgender individuals submitted to gender-affirming surgery (GAS). METHODS: A case series study was conducted from October 2016 to August 2018. Transgender women, who were scheduled for GAS, participated in the study. The volunteers were submitted to a clinical evaluation of the PFM followed by digital palpation (PERFECT method) and electromyography in the preoperative, 15, and 30 days after GAS. They responded to the International Consultation on Incontinence Questionnaire-Urinary Incontinence (UI)-Short Form to evaluate the effect of UI on quality of life and to questions related to the urinary, anorectal, and sexual symptoms. Fifteen days after the GAS, patients were instructed to perform perineal exercises at home, twice a day. RESULTS: The study sample consisted of 15 transgender women with an average age of 30.6 (SD = 6.7) years. There was a decline in median strength and sustained muscle contraction duration (PERFECT), in the electrical muscle activity (RMSmean and RMSmax) between pre-GAS and 15 days after GAS (p < 0.05). However, there was an increase in these parameters between 15 and 30 days after GAS (p < 0.05). Moreover, six patients exhibited pre-GAS UI, which continued after surgery, with a worsening of urgency symptoms and improvement in nocturia and postmicturition leakage. CONCLUSION: Strength, sustained muscle contraction duration, and PFM electrical activity may decline 15 days after GAS, returning to pre-GAS values in the first month after surgery.

Techniques for registration of myoelectric activity of women's pelvic floor muscles: a scoping review protocol.

OBJECTIVE: The objective of this review is to identify the most frequently used protocols for analyzing the myoelectric activity of the pelvic floor muscles during surface electromyography in women aged 18 years or older. INTRODUCTION: Surface electromyography is normally used in assessment and treatment for research purposes when it is intended to quantitatively measure the electrophysiological behavior of the neuromuscular system. However, although there are internationally standardized, non-invasive assessment protocols for most muscle groups, there is no consensus for pelvic floor muscles, which makes it difficult to standardize in scientific research and clinical applicability. INCLUSION CRITERIA: Studies that explore registration protocols and filtering parameters of surface electromyographic signals in women aged over 18 years old with or without pelvic floor dysfunction will be considered. Studies encompassing either electromyographic biofeedback as a treatment resource only or electroneuromyography (needle electrode) will be excluded. METHODS: Primary studies published in the previous 10 years in MEDLINE, Embase, Scopus, Web of Science, CINAHL, and Cochrane Central databases will be included. The search will encompass descriptors registered in MeSH. The identified articles will be assessed for eligibility by two independent reviewers in three stages: evaluation by title, abstract, and full text. If there is any disagreement, a third reviewer will be consulted. Data will be extracted and organized in standardized spreadsheets. The results will be assigned to categories in order to facilitate the organization of a protocol with the most commonly used parameters for non-invasive assessment of myoelectric activity of pelvic floor muscles.
