Transcutaneous Electrical Nerve Stimulation for Labor Pain Control in Combination With Cardiotocography

Transcutaneous electrical nerve stimulation (TENS) is a non-invasive electro-physical modality used for several pain conditions including labor pain control. Despite several years of research, there is still no agreement within the literature regarding the selection of TENS parameters. It is aimed to investigate TENS1 alternating between 4 to 100 Hz compared to sham-TENS. The present study aims to evaluate TENS in combination with cardiotocography (CTG). The combination of TENS with CTG in a feedback-loop has not been reported in any studies before.
