Comparison between Measurements Obtained with three Different Perineometers

Abstract

OBJECTIVE: To analyze the results obtained in the evaluation of intra-vaginal pressure using three different brands of perineometers in nulliparous volunteers. MATERIALS AND METHODS: Twenty nulliparous women with no anatomical alterations and/or dysfunction of the pelvic floor were enrolled in our study. All the women had the ability to voluntarily contract their PFM (Pelvic Floor Muscles), as assessed by digital palpation. The intra-vaginal pressure was assessed using three different brands of perineometer (Neurodyn EvolutionTM, SensuPowerTM and PeritronTM). Each volunteer was evaluated on three alternate days by a single examiner using a single brand of perineometer on each day. In the assessment, the volunteers were required to pull (contract) their PFM in and up as strongly as possible 3 times and to sustain the contraction for 5 seconds, with an interval of 30 seconds between each pull. For the statistical analysis, a concordance correlation coefficient was used to compare the values that were obtained with each brand of perineometer. RESULTS: A moderate concordance (0.51) was found between the results from the PeritronTM and NeurodynTM perineometers, a fair concordance (0.21) between the PeritronTM and SensuPowerTM brands and a poor concordance (0.19) between the NeurodynTM and SensuPowerTM brands. CONCLUSION: The concordance of the measurements of the intra-vaginal pressure ranged from poor to moderate, suggesting that perineometers of different brands generate different results

Avaliação Do Assoalho Pélvico De Atletas: Existe Relação Com a Incontinência Urinária?

“…O sensor de pressão foi introduzido na vagina, e automaticamente foi quantificada a pressão vaginal de repouso (musculatura em repouso). O aparelho foi zerado e solicitou-se uma contração máxima, por pelo menos três segundos (pressão vaginal máxima) 21 .…”

Correlation between maximum voluntary contraction and endurance measured by digital palpation and manometry: An observational study

“…10 In recent years, different methods have been developed to evaluate PFM function quantitatively. 11,12 The measurement of vaginal pressure has been considered a reproducible method. 13,14 However, practitioners should be aware that increased intra-abdominal pressure might occur during the evaluation and influence the results.…”

Evaluation of pelvic floor muscle anatomy and function in women: modern techniques

“…Dlatego należy podkreślić, że zastosowanie perineometrii jest trudne i dyskusyjne przy bardzo słabej sile PFM, gdyż ruch sondy do wewnątrz jest praktycznie niemożliwy. Rozmiar sondy i jej marka były również rozpatrywane w aspekcie jej wpływu na pomiar [37,38]. Jeszcze jednym ważnym czynnikiem jest sposób zało-żenia sondy.…”
