Effects of transcutaneous electrical nerve stimulation (TENS) on labor pain

Based on the gate theory of pain, an apparatus was manufactured for transcutaneous electrical nerve stimulation (TENS) that relieves some pains. Since this method inflicts no harm to the patients and due to cultural and environmental effects on the intensity and tolerance of pain, this study was performed to determine the effectiveness of the method on alleviating of labor pain in the province of Chahar Mahal & Bakhtiary. TENS was used in 50 nulliparous patients and reduction of pain intensity, duration of delivery as well as patientsʹ inclination for future use of TENS, were compared to those of a control group that used placebo. Our results showed that there was a marked reduction in the duration of active phase of labor and a higher tolerance of labor pain and a higher inclination for reuse of the method in the case group compared to those of the control group. 52% of the case group inclined to reuse TENS for future labor. Also there was no significant reduction of labor pain in the case group. It can be concluded that due to the effectiveness of this method, its usage is advisable.
