研究概览
简要总结
The researchers want to see if nerve stimulation interventions cause a change in vaginal blood flow. This intervention was performed in women who have neurogenic (spinal cord injury) or non-neurogenic sexual dysfunction and healthy women.
详细描述
Two nerve stimulation locations (genital nerve and tibial nerve) were targeted with skin-surface electrical stimulation in separate experimental sessions.
This study was designed as a crossover study, but all participant data was analyzed together due to small enrollment size.

结局指标
主要结局
Percent Change in Average Vaginal Pulse Amplitude (VPA) During Stimulation From the Average Baseline Value
时间窗: Test baseline (approximately minute 0) up to Test completion (approximately minute 60)
VPA will be measured by a vaginal plethysmography transducer. A sensor placed in the vagina will measure changes in blood flow.
次要结局
- Percent Change in Heart Rate After Stimulation From Baseline(Test baseline (approximately minute 0) up to Test completion (approximately minute 60))
- Percent Change in Mean Arterial Blood Pressure During Stimulation From Baseline(Test baseline (approximately minute 0) up to Test completion (approximately minute 60))
- Change in Subjective Arousal After Stimulation(Test baseline (approximately minute 0) up to Test completion (approximately minute 60))
