The circumvaginal musculature: correlation between pressure and physical assessment.
This study assessed two recently developed techniques to assess the circumvaginal musculature (CVM), the CVM Rating Scale and the pressure sensitive intravaginal balloon device (IVBD), and correlated results of the two methods. Thirty women volunteers, aged 20 to 42, were studied. CVM Rating Scale total scores and IVBD maximal contraction variables were measured for resting pressure, rate of rise, maximal pressure, rate of return, and time that a submaximal contraction could be sustained (endurance contraction). Age, parity, self-reported orgasm, self-reported Kegel exercises, and self-reported physical exercise were separately correlated with CVM Rating Scale total scores and IVBD maximal pressure results. A positive significant correlation was found between the CVM Rating Scale total scores and the IVBD maximal contraction results for the variables rate of rise, r = .50, p less than .01, maximum pressure, r = .82, p less than .01, and rate of return, r = .44, p less than .01. Self-reported orgasm had a positive significant correlation to the CVM Rating Scale total scores, rho = .34, p less than .05, and to the IVBD maximal pressure results, r = .52, p less than .01. A positive correlation was found between self-reported physical exercise and the CVM Rating Scale total scores, rho = .31, p less than .05. IBVD maximal pressure results were negatively correlated with age, r = -.34, p less than .05, and parity, r = -.34, p less than .05.
