Abstract

• The effect of circumvaginal muscle (CVM) exercises to improve sexual function in married women has not been investigated by currently acceptable research methods, nor have appropriate instruments and techniques to carry out such investigation been available. The purpose of this research was to study the effect of CVM exercise on sexual function, and of measuring CVM function after CVM exercises. The research tools used were a modified Derogatis Sexual Function Inventory questionnare and a pressure sensitive intravaginal balloon device. This research was conducted in Kwangju-city and Chonnam province, Korea from July, 1994 to July, 1995. The research used a non-equivalent control pre-post test quasi-experimental design. Forty-five healthy married female volunteers, aged 30?8, and were randomly assigned by age using the matching fixed-length blocks to two groups. The experimental group consisted of 21 women who were assigned a 25 -minute per day CVM home exercise program for six weeks. The control group of 24 women did not do the CVM home exercises. The CVM home exercise was developed by Dougherty (1989a) and adopted to Korea by Lee (1993). Data were analyzed by x2-test, Paired t-test, Spearman product-moment correlation using SAS/PC+. The results are summarized as follows: 1. There were no significant differences in the characteristics of the subjects between the exper imental and control groups before the CVM home exercises. 2. Hypothesis 1 that married women who participated in CVM home exercises would have higher mean scores on the sexual function (SF) than in those who did not participate in home exercise was supported. 3. Hypothesis 2 that married women who participated in CVM home exercises would have higher vaginal pressure on SF than in those who did not participate in home exercises was supported (mean maximum pressure, t= -7.338, P<.0001, peak maximum pressure, t=-11.164, P<.0001). 4. Hypothesis 3 that the more often (number of days) and the more frequent (numbers of times per day) that married women do CVM home exercise, the higher their mean scores on SF and vaginal pressures was supported (r =0.233, P<.01; r=0.352, P<.05). A six week CVM home exercise program using a tape recording showed that SF can be improved. Results of this study showed that married women who exercise on a regular basis for six weeks improve their sexual function and increase the mean vaginal pressure and peak maximum pressure (tested by electronic monitor). In conclusion, CVM exercise is effective in increasing SF.
