Electromyographic Response of the Pelvic Floor Muscles in Female Sex Workers [23I

Abstract

INTRODUCTION: Sex workers are exposed to situations of vulnerability and may have intercourse many times a day. This intense, constant sexual activity may result in changes to the vagina, overburdening the perineum and other pelvic muscles. Various studies have evaluated PF muscle function in different groups of women. METHODS: A cross-sectional, observational study was conducted with 30 female sex workers aged 18-56 years. The study was approved by local IRB. All the women underwent electromyographic evaluation. RESULTS: A negative correlation was found between electromyographic activity of the pelvic floor muscles and age (r = -0.369; p=0.045), weight (r = -0.401; p=0.028), body mass index (r = -0.412; p=0.024) and number of pregnancies (r = -0.399; p=0.029). Electromyographic activity of the external pelvic floor muscles was greater in the women who worked longer hours compared to those working fewer hours/day (p<0.001). No statistically significant difference was found in relation to skin color, time working in the profession or number of partners per day. CONCLUSION: No correlation was found between the frequency and intensity of sexual activity and electromyographic activity of the pelvic floor muscles in this group of female sex workers; however, electromyographic activity of the external pelvic floor muscles was greater in the women who worked longer hours.
