<qa>  What was the cranial elevation movement observed by the examiner?Study design - this study was conducted in Cinesiofunctional Performance Laboratory Pelvic and Womens Health at the Federal University of Uberlandia UFU, the volunteers were recruited from December 2014 to July 2015. This is an observational, cross-sectional and comparative study, the sample consisted of 141 nulliparous women non-pregnant nulliparous or primigravids. All volunteer shave signed an informed consent and the study was approved by the Ethics Committee of the Federal University of Uberlandia No.10671622014. Female students of UFU were invited by personal contact to participate in the study. The primigravids were participants in the Prenatal Program of the public health system in Uberlandia city and they have also been invited by personal contact. Inclusion criterion for volunteers were: never have passed for childbirth situation,ability to contract correctly the PFM and without urogynecological complaints. Exclusion criterion were: history of previous pelvic surgery, without previous sexual intercourse, and present neuromuscular diseases. The experient examiner, with expertise in PFM evaluation conducted the evaluations. After checking that they were eligible to participate in the survey, participants were asked to empty the bladder and to remain in the supine position on an appropriate bed with hips and knees flexed and maintaining the lumbar spine in neutral position.The PFM assessment was performed by vaginal palpation, vaginal squeeze pressure and dynamometry. The vaginal palpation and vaginal squeeze pressure are widely used in research involving the female pelvic floor and many studies have shown its reproducibility and validity10, 11, 12, 13. The measurements performed with a dynamometer in this study were similar to the study of Martinho et al4 which used the same instrument and have demonstrated reproducibility of the assessment method. During all PFM assessments, the volunteer was advised to stay relaxed and breathing normally. To be considered valid, the cranial elevation movement was observed by the examiner, as well as the absence of visible contractions of the adductor, muscles of the hip, gluteal muscles or abdominals. Strong verbal command was adopted to request the PFM contraction in all exams.
