简要总结
This study will examine whether measurement of pelvic floor muscle sEMG activity is responsive to explicit sexual stimuli, and whether it correlates with self-reports of sexual arousal in healthy women. Participants' vaginal, labial and anal sEMG readings will be monitored during exposure to neutral, erotic and anxiety-provoking films. Participants will also be required to provide subjective ratings of sexual arousal before and after each film. If pelvic floor sEMG is validated as a psychophysiological measure, these findings may have important clinical and research implications by providing a greater understanding of the mechanisms involved in sexual arousal and for providing a relatively easy method of assessing sexual arousal in a clinical or research setting.
详细描述
HYPOTHESES:
- Investigators hypothesize that, relative to the neutral films, PFM EMG activity will significantly increase in response to the erotic film as measured by the labial, anal, and vaginal EMG probes.
- Investigators hypothesize that, relative to the anxiety-provoking film, PFM EMG activity will significantly increase in response to the erotic film as measured by the labial, anal, and vaginal EMG probes.
- Investigators hypothesize that continuously measured subjective sexual arousal (via the arousometer) will correlate significantly with PFM EMG activity during the erotic film.
