“…Ainda assim, é importante reconhecer que o aparelho utilizado não permite detectar a presença dos principais músculos que atuam junto com a contração perineal. Por outro lado, dados da literatura mostram que quando isolada a ação desses músculos, restando somente o recrutamento da musculatura perineal com boa eficiência, existe uma forte correlação entre os achados da perineometria e da eletromiografia [29]. Ainda, é importante considerar o constatado por Rahmani et al [21], que afirmam que o perineômetro pode não ter a precisão desejável, mas isso não impede que as medidas obtidas sirvam de parâmetro na avaliação da pressão perineal.…”

AIMS: To verify intra and inter-rater reliability and concordance in the assessment of perineal pressure in nulliparous women.METHODS: Young, healthy, nulliparous, non-pregnant women who had had sexual intercourse and had a correct contraction of the perineal musculature on physical examination were included. Women were excluded if they used other muscles in a visually perceptible way during the perineal contraction; with changes in the pelvic muscles tone; with urinary incontinence; with cognitive alterations; with disease that could affect the muscular and nervous tissues; or practitioners of high-impact physical activity. The participants were submitted to two assessments of perineal pressure on the same day, with different evaluators. After one week the protocol was repeated. Perineal pressure was determined by means of a perineometer and obtained by the difference between the maximum pressure (Pmax) and the minimum pressure (Pmin) recorded by the device, in millimeters of mercury. Sustained contraction (SC) was evaluated by the time in seconds. In order to determine reliability, the intraclass correlation coefficient (ICC) was used. Bland-Altman test was used for the concordance analysis. Comparison of means was performed by the Wilcoxon test. A value of p≤0.05 was considered significant.RESULTS: Ten participants were included, with a mean age of 23.8±2.9 years and a body mass index of 22.2±1.8 kg / m². The evaluator A obtained excellent intra-rater reliability for Pmin (ICC=0.86, p<0.01) and Pmax (ICC=0.92, p<0.01); very good reliability for perineal pressure (ICC=0.65, p=0.01); and no statistical significance for SC. For evaluator B, there was no statistical significance for Pmin and Pmax, but there was very good reliability for perineal pressure (ICC=0.78, p<0.01) and SC (ICC = 0.70, p<0.01). In the inter-rater analysis (A vs B), on day 1 there was no statistical significance for Pmin, Pmax and perineal pressure; but there was very good reliability for SC (ICC=0.71, p<0.01). On day 2, there was no statistical significance for Pmin and Pmax, but there was very good reliability for perineal pressure (ICC=0.62, p=0.02) and good for SC (ICC=0.56, p=0.03). There was agreement between intra and inter-rater measurements.CONCLUSIONS: Perineal pressure measurements showed very good intra-rater reliability and good to very good inter-rater reliability, with intra and inter-rater concordance.

“…Initially, women were instructed on how to perform a correct PFM contraction, defined as an inward lift and squeeze around the pelvic openings. Images and anatomical models were used to explain the anatomy and function of the pelvic floor, and vaginal palpation was performed to ensure the ability to contract 13,15–18 …”

Then, they entered a supine position with hips flexed at 45°and slightly abducted, knees flexed at 90°with feet resting on the table.…”

Background Vaginal birth is a risk factor for weakening of the pelvic floor muscles (PFM) and development of pelvic floor dysfunction (PFD). Perineal tears may decrease PFM function. PFM tone can be assessed with surface EMG (sEMG), but reliability studies of sEMG in women with perineal tears are lacking. The aims of this study were to evaluate test–retest and intrarater reliability of sEMG and compare PFM activation between nulliparous and primiparous. Methods A sEMG test–retest was performed in 21 women (12 nulliparous and 9 primiparous with grade II tears) to assess intra‐rater reliability during rest and maximal voluntary contraction (MVC) of the PFM. Intraclass Correlation Coefficient (ICC), standard error of measurement (SEM) and minimal detectable change (MDC) were tested. A comparison between nulliparous' and primiparous' PFM activation during rest and MVC was performed. Results sEMG demonstrated fair reliability in nulliparous (ICC: 0.239; SEM: 5.2; MDC: 14.5) and moderate reliability in primiparous (ICC: 0.409; SEM: 1.5; MDC: 4.2) during rest. For peak MVC very good intrarater reliability was found in nulliparous (ICC: 0.92; SEM: 8.0; MDC: 22.2) and in primiparous (ICC: 0.823; SEM: 8.0; MDC: 22.2). Statistically significant lower PFM activation was found in primiparous women with perineal tear grade II than in nulliparous at rest (mean difference 9.1 µV, 95% confidence interval [CI] 3.0–19.0, p = 0.001), and during MVCpeak (mean difference 50.0 µV, 95% CI 10.0–120.0 p = 0.021). Conclusions sEMG is reliable when measuring PFM activation in primiparous women with perineal tears grade II. Women with perineal tears grade II have lower PFM activation both during rest and MVC.

“…(ANDREW et al, 2005;THOMPSON et al, 2006; RAHMANI; MOHSENI-BANDPEI, 2011). Estudos recentes mostram que apesar de se tratar de um aparelho simples, os resultados obtidos pelo perineômetro apresentam forte correlação com os achados eletromiográficos sobre a função dos MAP (MACÊDO et al, 2018;SARTORI et al, 2019). anos, a média das contrações rápidas em T0 se aproximou ao de outro estudo brasileiro que a média de valor de 13,1 (DP=7.3), porém a média das contrações lentas encontradas no presente estudo foi superior (SARTORI et al, 2019).…”
