ReviewTranscutaneous electrical nerve stimulation in labour pain: a systematic review.
To review the effectiveness and safety of transcutaneous electrical nerve stimulation (TENS) for labour pain. ⋯ Randomised controlled trials provide no compelling evidence for TENS having any analgesic effect during labour. Weak positive effects in secondary (analgesic sparing) and tertiary (choosing TENS for future labours) outcomes may be due to inadequate blinding causing overestimation of treatment effects.
