title: Assessment of perineal floor function: electromyography with acrylic plug surface electrodes in nulliparous women.
abstract: A new technique using acrylic plug surface electrodes was employed to record electromyographic activity in the musculature surrounding the rectum and vagina. Forty-one asymptomatic nulliparous women were tested. The group had a wide range of normal values. When eight women were chosen at random for a second testing session, intra-class correlation coefficients to compare readings between the two sessions ranged from 0.76-0.97, indicating adequate reliability. No demographic factor correlated with the voltage generated in these women.
