Assessment of pelvic floor function: a series of simple tests in nulliparous women.

The aim of the study was to assess normal ranges, variations, test-retest reliability and correlations between tests for a battery of simple, minimally invasive tests of pelvic floor function in nulliparous asymptomatic women. Women were recruited by advertisement and underwent dipstick urinalysis, simple cystometrics, provocative tests for incontinence, Q-tip test and surface electromyography with acrylic plug electrodes. Subjects were retested at a later date. Nineteen subjects underwent initial testing and 12 were retested. A wide range of normal values was obtained. Cystometric measures of first and strong urge to void the maximum bladder capacity, Q-tip test and rectal perineometry had significant correlations between the two visits. There were no significant between-test correlation coefficients. It was concluded that the simple tests used demonstrate a mixed ability to follow pelvic floor function longitudinally.
