The ability to contract the pelvic floor may be assessed during pelvic exam with a Brink's score. However, there are still elements of subjectivity in components of this score and researchers continue to look for an objective measure of pelvic floor muscle tone. The Peritron perineometer device has been shown to correlate well with pelvic floor contraction, based on Brinks scores.Measurements taken with the Peritron device have better inter-rater reliability than other measures of pelvic floor contraction, which makes it an attractive tool for clinical research. However, its use in clinical research is hampered by the lack of normative data with perineometer measurements. Though there are some studies that use the perineometer to assess resting (i.e. non-contracted) pelvic tone after therapies for pelvic pain, there are no studies that assess the typical perineometer measurements in women with levator spasm, and there are no data to guide how these measurements may compare with women having a normal pelvic floor examination. We hypothesize that: 1) Women with high resting pelvic tone perceived on exam will have high perineometer measurements and women with normal pelvic tone on exam will have low perineometer measurements, regardless of whether or not they report pelvic pain. 2) Women with high resting perineometer measurements will have minimal change in perineometer scores between resting and maximum pelvic floor contraction (squeeze). 3) In women with clinical evidence of levator spasm, resting perineometer measurements will correlate with severity of pelvic pain symptoms. We plan to investigate these hypotheses by executing the following specific aims:
