Seventy parturient women were randomized into two groups, one receiving transcutaneous nerve stimulation, the other mock stimulation with an identical looking apparatus. The patients' assessment of pain relief and the use of analgesics during labor were recorded. There was no difference between the two groups in the degree of pain relief. There was no reduction in the need for analgesics which could be ascribed to the use of nerve stimulation. The use of analgesics in each patient was correlated to the duration of labor.
70名产妇被随机分为两组，一组接受经皮神经刺激，另一组使用外观相同的仪器进行模拟刺激。记录患者对分娩期间疼痛缓解的评估以及镇痛药的使用情况。两组在疼痛缓解程度上没有差异。神经刺激的使用并未减少镇痛药的需求。每位患者的镇痛药使用情况与产程时长相关。
