There was a correlation between pelvic floor muscle contractility measured by surface electromyography and by digital palpation. Both methods can be used to validate data in research and clinical setting.

PURPOSE: to translate, culturally adapt and validate the questionnaire "International Consultation on Incontinence Questionnaire Overactive Bladder" (ICIQ-OAB) for the Portuguese Language. METHODS: two Brazilian translators acquainted with the objectives of this research translated the ICIQ-OAB into Portuguese and both translations were back-translated by two other native English speaking translators. The differences between the versions were brought to agreement and pre-tested in a pilot study. The final version of the ICIQ-OAB was applied together with the previously translated and tested version of the International Consultation on Incontinence Questionnaire -Short Form (ICIQ-SF) in 142 male and female patients with irritative urinary symptoms. For the validation of the ICIQ-OAB the following psychometric features were evaluated: reliability (internal consistency and test-retest) and validity of the survey. The retest was performed four weeks after the first interview. RESULTS: the reliability of the instrument was demonstrated through the Cronbach α Coefficient, with a general result of 0.7. The test-retest corroborated the stability of the instrument through the intraclass correlation coefficient and presented a result of 0.91 and 0.95 when compared to both the ICIQ-OAB and ICIQ-SF, respectively. When the instruments were compared by the Pearson correlation coefficient the result was 0.7 (p=0.0001), that confirms the validity of the study criterion. The concurrent validity was evaluated by

Vaginal delivery was associated with a decrease in pelvic floor muscle strength and endurance 45 days after delivery when compared to elective cesarean section as well as emergency cesarean section.

There is co-activation of the transversus abdominis/internal oblique and the pelvic floor muscles in young, asymptomatic nulliparous women. This pattern was modified in primigravid pregnant and primiparous postpartum women regardless of the delivery mode.
