简要总结
This study aims to investigate the effects of transcutaneous auricular vagus nerve stimulation (taVNS) on menstrual pain, pain threshold, depression, anxiety, menstrual symptoms, premenstrual syndrome, and functional and emotional impact of dysmenorrhea in young adult women with primary dysmenorrhea.
详细描述
Primary dysmenorrhea is a common condition affecting young women and is associated with significant physical and psychological symptoms. Non-invasive neuromodulation techniques such as transcutaneous auricular vagus nerve stimulation (taVNS) have gained attention as potential therapeutic approaches.
In this randomized controlled study, women diagnosed with primary dysmenorrhea will be randomly assigned to either an active taVNS group or a sham stimulation group. The intervention will be applied during the luteal phase between two consecutive menstrual cycles, totaling 10 sessions.
Outcome measures will include pain intensity, pain threshold, depression, anxiety, menstrual symptoms, premenstrual syndrome severity, and functional and emotional impact of dysmenorrhea.

结局指标
主要结局
Menstrual pain intensity
时间窗: Baseline (Cycle 1, Day 1 or Day 2 of menstruation). Cycle 2, Day 1 or Day 2 of menstruation (approximately one menstrual cycle [21-35 days] after baseline).
Menstrual pain intensity is assessed using the Visual Analog Scale (VAS). Scores range from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain. Higher scores indicate greater pain intensity.
Pain threshold
时间窗: Baseline (Cycle 1, Day 1 or Day 2 of menstruation). Cycle 2, Day 1 or Day 2 of menstruation (approximately one menstrual cycle [21-35 days] after baseline).
Pain threshold is assessed using a pressure algometer. The pressure pain threshold is recorded in lb/cm². Higher values indicate a higher pressure pain threshold and lower pain sensitivity.
次要结局
- Depression level(Baseline (Cycle 1, Day 1 or Day 2 of menstruation). Cycle 2, Day 1 or Day 2 of menstruation (approximately one menstrual cycle [21-35 days] after baseline).)
- Anxiety level(Baseline (Cycle 1, Day 1 or Day 2 of menstruation). Cycle 2, Day 1 or Day 2 of menstruation (approximately one menstrual cycle [21-35 days] after baseline).)
- Menstrual symptoms(Baseline (Cycle 1, Day 1 or Day 2 of menstruation). Cycle 2, Day 1 or Day 2 of menstruation (approximately one menstrual cycle [21-35 days] after baseline).)
- Premenstrual syndrome severity(Baseline (Cycle 1, Day 1 or Day 2 of menstruation). Cycle 2, Day 1 or Day 2 of menstruation (approximately one menstrual cycle [21-35 days] after baseline).)
- Functional and emotional impact of dysmenorrhea(Baseline (Cycle 1, Day 1 or Day 2 of menstruation). Cycle 2, Day 1 or Day 2 of menstruation (approximately one menstrual cycle [21-35 days] after baseline).)
