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) lorenametaute.com 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 hindirochakkahaniya.com 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.
