ObjectiveTo assess the effect of order of sensitivity testing at the vulva and thumb on the sensitivity determined at the second site tested among women with and without vulvodynia.Study DesignWe evaluated the stability of sensitivity measurements to pressure at the vulva and thumb when the order of testing was randomized to vulva first vs. thumb first; we repeated testing 1 week later in the opposite order.ResultsStability of results over time and the influence of the order of testing were determined among 13 women with vulvodynia and 20 asymptomatic control women. We found a strong correlation between results compared between the first and second visits as well as no order effect.ConclusionThe order of testing at vulvar and peripheral sites has little impact on the results of pressure-responsive sensitivity testing among women with and without vulvodynia.
