Friedman (1954) describes a sigmoid pattern for labor. This study is carried out to identify the trend of labor progression in multiparous women. Materials and Methods: The present cohort study was conducted on 336 multiparous women. In order to assess labor stages, dilatation per unit of time was evaluated in each participant. Participants were divided into four groups: non intervention, induced, sedated, and both intervention groups. The related parameters were evaluated in all groups. Data was analyzed using one way analysis of variance, one sample t-test and mixed model regression models in reverse method for drawing the curve. Results: In all groups, with the increasing expansion of cervix the rate of cervix dilatation was increased. A significant relationship was observed between expansion speed rate in active phase of the first stage and the third stage, with induction of labor (p }, URL = {http://jams.arakmu.ac.ir/article-1-190-en.html}, eprint = {http://jams.arakmu.ac.ir/article-1-190-en.pdf}, journal = {Journal of Arak University of Medical Sciences}, doi = {}, year = {2008} }
