2 November 2008	Amended	Converted to new review format.
28 February 2006	New search has been performed	Ten new trials identified: six trials were included in the review, including two trials of hypnosis, two acupressure trials and two acupuncture trials. Four trials were excluded. We have removed trials of biofeedback from this update because they will be reviewed separately in the review following the newly published protocol 'Biofeedback for pain during labour'. Trials with a loss greater than 25% were not excluded from the analysis. A sensitivity analysis was undertaken on trials with a loss to follow up of 25% or greater.
