Trial Outcomes & Findings for Effect of Peripheral Neuromodulation on Vaginal Blood Flow - Study 2 (NCT NCT06999265)

NCT ID: NCT06999265

Last Updated: 2025-07-16

Results Overview

VPA will be measured by a vaginal plethysmography transducer that is placed in the vagina to measure changes in blood flow during the full study session. Overall treatment sequence: baseline (nature) video erotic video 1 (no treatment = "control") baseline nature video (treatment on in middle) erotic video 2 (treatment) The average VPA value during the baseline period will be determined. The maximum percent change in VPA during each relevant sequence as compared to the average baseline VPA will be determined for each participant.

Tibial Nerve Stimulation, Then Genital Nerve Stimulation
Participants in this arm received tibial nerve stimulation during their first study visit. Those who returned for the second study visit then received genital nerve stimulation. Film Clip Alternation will take place during both interventions. Transcutaneous electrical nerve stimulation (TENS) - Tibial Nerve: TENS device (Empi Select 199584, Medi-Stim Inc.) Electrical stimulation applied to target the tibial nerve on one leg, with electrodes above the malleolus and on the bottom of the foot Transcutaneous electrical nerve stimulation (TENS) - Genital Nerve: TENS device (Empi Select 199584, Medi-Stim Inc.) Electrical stimulation applied to target the genital nerve, with electrodes on either side of the clitoris. Neutral and Erotic Film Clip Alternation: During the testing period, participants will first view a 5-minute neutral film depicting nature scenes to allow blood flow levels to stabilize. This will be followed by a 10-minute period while the subject watches an erotic film clip for assessment of arousal responses without electrical stimulation. A 10-minute clip of the same neutral film will follow, to allow blood flow levels to return to baseline. Five minutes into this film, electrical stimulation will be resumed at the previously determined amplitude. Finally, the subject will view another 10-minute erotic film clip depicting similar sexually explicit material as the first while electrical stimulation remains on as the last sequence in the testing.

PRIMARY outcome

Timeframe: Up to five months

Population: Analysis population is all participants who received the designated treatment, regardless of which treatment they received first or if they continued to the second treatment.

VPA will be measured by a vaginal plethysmography transducer that is placed in the vagina to measure changes in blood flow during the full study session. Overall treatment sequence: baseline (nature) video erotic video 1 (no treatment = "control") baseline nature video (treatment on in middle) erotic video 2 (treatment) The average VPA value during the baseline period will be determined. The maximum percent change in VPA during each relevant sequence as compared to the average baseline VPA will be determined for each participant.

A heart rate monitor (e.g. electrocardiogram or pulse oximetry) will be placed on the participant's arm, hand, or chest (as is appropriate per monitor) to measure the heart rate in beats per minute (bpm). The average heart rate in bpm during the baseline video will be determined. The average percent change in heart rate during each test sequence as compared to the average baseline heart rate will be determined.

Population: Analysis population is all participants who received the designated treatment, regardless of which treatment they received first or if they continued to the second treatment.

A blood pressure monitor will be placed on the participant's arm, hand, or chest (as is appropriate per monitor) to monitor off-target autonomic responses. The mean arterial blood pressure in millimeters of mercury (mm Hg) will be calculated for a period as the diastolic pressure plus 1/3 times the difference between the systolic pressure and the diastolic pressure, following standard practice. The average mean arterial blood pressure will be determined for the baseline period. The percent change in average mean arterial blood pressure with respect to the baseline period will be determined for each test sequence.
