This study assessed the relationship between involuntary pelvic floor muscle activity, muscle awareness and experienced threat in women with and without vaginismus. Information about this relationship may help understand the mechanism of vaginismus. Twenty-two women with vaginismus and seven control women participated in the study. Women were exposed to four emotion-inducing film excerpts. Vaginal electromyography was recorded. Experienced threat was continuously monitored with the use of a lever. Women responded with increased pelvic floor muscle activity to the threatening and sexually-threatening film excerpt. No changes occurred during the neutral and erotic excerpt. The subjective experienced threat as indicated with the lever showed the same response pattern. However, awareness of changes in muscle activity showed a slightly different pattern. Individual data were inspected. In general, agreement was found between recorded changes in muscle activity and experienced threat. The results of the erotic excerpt showed that awareness of changes in muscle activity is not only determined by information from the pelvic floor muscles, but also by other factors like situational information and the expectations of the women. The data support the idea of a general defense reaction as a mechanism of involuntary pelvic floor muscle activity. |
