Analysis of Influencing Factors on Circumvaginal Muscle Function in Married Women
Lee Young-Sook

Abstract
This research was conducted to explore the level of circumvaginal muscle(CVM) function and to determine the factors influencing circumvaginal muscle function in married women. The research tools used were a modified Hendickson¡¯s questionnaire, a CVM rating scale and a electronic monitoring system connected to a pressure sensitive intravaginal ballon device(IVBD). The measurement and interview were carried out at the experimental research clinic of Department of Nursing, Medical College, Chonnam National University in Kwangju-City, Korea from March to February 1997. Study subjects were 45 healthy married female volunteers of 30¡­59 years old. Calculation of Pearson¡¯s correlation coefficient and multiple regression analysis were carried out by computer using SAS/PC. The mean pressure of CVM was 20.5mmHg and the maximum pressure of CVM was 29.3mmHg. Digital measurement score of pelvic muscle strength was 9.4 points(range : 0¡­12 points) and relaxation score of the pelvic muscle 22.4 points(range : 0¡­60 points). The CVM scale showed a significant inverse relationship with the relaxation scores of the pelvic muscle. Influencing variables to mean pressure and maximum pressure of CVM in multiple regression analysis were pelvic muscle strength, number of vaginal delivery and cesarean section. Influencing variables to relaxation scores of the pelvic muscle in multiple regression analysis were periods of stress incontinence, pelvic muscle strength, number of vaginal delivery, orgasm, number of sex, and episiotomy of last delivery. Influencing variables to pelvic muscle strength in multiple regression analysis were pelvic muscle relaxation, number of vaginal delivery, maximum pressure of CVM, and birth weight of last baby. There was a significant correlation in results from the subjective, digital and pressure measuring methods on the CVM function. The subjective and digital measurements of CVM function can be easily applied to prevention, detection and control of CVM function for women without using the electronic monitor.
