Introduction: Although for most women childbirth is one of the most beautiful experiences in their lifetime, it is mostly accompanied by severe pain as a result of anatomical-physiological changes. It is affected by various cultural, environmental and social factors before it is actually even felt. We use a variety of pharmacological and non-pharmacological techniques to relieve labour pain and thus prevent from possible complications. One of the less commonly used techniques is the use of Transcutaneous Electrical Nerve Stimulation (TENS), which is based on the theory of gate control, and has been used in obstetrics since 1970. Purpose: The purpose of this diploma work was to review scientific studies of the effects of TENS on pain relief during labour. Methods: Articles and literature were searched in PubMed, CINAHL, PEDro and COBISS+ databases. Selected literature in Slovene and English language, published after year 2005, was found with the help of key words: TENS, labour, labour pain, physiotherapy. Results: Based on inclusion and exclusion criteria, eight studies were selected. In all studies, TENS was used to relieve labour pain. Its use to reduce pain during the episiotomy procedure was examined in one study. Authors found that the use of TENS statistically and clinically made significant contribution to the relief of labour pain compared to conventional care, but did not significantly reduce pain during episiotomy cutting. Among other things, its use did not affect the duration of labour and the Apgar score of the newborn, measured in the 1st and 5th minute after birth. Discussion and conclusion: The results obtained with the literature review are indicating that TENS is an effective method for pain relief during labour. To define its effects better, further research should be done.
