A study of the effects of biofeedback on the pain of childbirth was conducted. Forty primigravidae were randomly assigned to either an experimental group or a control group. The experimental group was given a series of training sessions in biofeedback and used biofeedback equipment during labor. All subjects were monitored during the labor and delivery period for their reports of pain using a visual analogue scale (VAS) and a verbal descriptor scale (VDS). Results showed that women using biofeedback during childbirth reported significantly lower pain: from admission to labor and delivery (p less than 0.05:VDS; p less than 0.01:VAS), at delivery (p less than 0.005:VDS), and 24-hr postpartum (p less than 0.01:VDS). Also, women in the biofeedback group labored an average of 2 hr less and used 30% fewer medications. The results of this study suggest that EMG biofeedback may be effective in reducing levels of acute pain experienced by childbearing women.
一项关于生物反馈对分娩疼痛影响的研究展开了。40名初产妇被随机分为实验组或对照组。实验组接受了一系列生物反馈训练课程，并在分娩期间使用生物反馈设备。在分娩和产褥期，使用视觉模拟量表（VAS）和言语描述量表（VDS）对所有受试者的疼痛报告进行监测。结果显示，分娩时使用生物反馈的女性报告的疼痛明显更低：从入院到分娩和产褥期（p<0.05：VDS；p<0.01：VAS），分娩时（p<0.005：VDS），以及产后24小时（p<0.01：VDS）。此外，生物反馈组的女性平均分娩时间少2小时，用药量少30%。这项研究结果表明，肌电图生物反馈可能有效降低生育期女性的急性疼痛水平。
