To compare the physiological sexual responses of women with complete spinal cord injuries (SCIs) with those of able-bodies women.
Controlled laboratory-based analysis of responses to audiovisual erotic and audiovisual erotic combined with manual stimulation.
The sexual physiology laboratory at our free-standing rehabilitation hospital.
A volunteer sample of 13 women with complete SCIs above T6 along with eight able-bodies women, matched for age and educational status.
A 78-minute protocol using 6-minute baseline alternating with 12-minute testing conditions was conducted.
Included vaginal pulse amplitude, subjective arousal, heart rate, blood pressure, and respiratory rate.
Showed comparable increases in subjective arousal in both groups with audiovisual but not audiovisual combined with manual stimulation. Vaginal pulse amplitude increased in able-bodied subjects but no SCI subjects with isolated audiovisual stimulation; however, with the addition of manual stimulation all subjects responded similarly. Other nongenital correlates of sexual arousal were similar between SCI and able-bodies subjects.
These results provide physiological validation of the hypothesis that women with complete SCI can respond with audiovisual stimulation similarly to able-bodies women in those functions that are controlled neurologically above the level of their injuries, whereas, genital vasocongestion will not occur because the neurological pathway is interrupted. In contrast, reflex genital vasocongestion can occur in women with complete SCI despite a lack of subjective arousal. These findings can be used to educate women with complete SCIs about their sexual responses.
比较完全性脊髓损伤（SCI）女性与身体健全女性的生理性性反应。
基于实验室的对照分析，观察对视听色情刺激以及视听色情刺激结合手动刺激的反应。
我们独立康复医院的性生理实验室。
13名T6以上完全性SCI女性的志愿者样本以及8名年龄和教育程度匹配的身体健全女性。
采用一个78分钟的方案，6分钟基线期与12分钟测试期交替进行。
包括阴道脉搏振幅、主观唤起、心率、血压和呼吸频率。
两组在视听刺激时主观唤起均有类似增加，但在视听刺激结合手动刺激时并非如此。身体健全的受试者在单纯视听刺激时阴道脉搏振幅增加，而完全性SCI受试者无此变化；然而，加入手动刺激后所有受试者反应相似。SCI受试者与身体健全受试者之间性唤起的其他非生殖器相关指标相似。
这些结果为以下假设提供了生理学验证，即完全性SCI女性在其损伤水平以上神经控制的功能方面，对视听刺激的反应与身体健全女性相似，而由于神经通路中断不会发生生殖器血管充血。相反，尽管缺乏主观唤起，完全性SCI女性仍可发生反射性生殖器血管充血。这些发现可用于对完全性SCI女性进行性反应方面的教育。
