Abstract
Introduction: Prolonged labor is an important problem during labor which can have undesirable effects on both maternal and fetal health. Shortening the duration of labor has always been one of the aims of obstetricians. Hence, the purpose of this research was to investigate the effect of massage on the duration of labor in women attending to Bentolhoda Maternity Unit in the city of Bojnord, Northern Khorasan, Iran in 2005. Materials and Methods: In this clinical tial study, 62 primiparous women with normal pregnancy were participated. The indications of normal pregnancy included a gestational age of 37-42 weeks, single tone, and vertex presentation. Sampling was done by purposive method. Women were randomly allocated in two groups. The experimental group (n=32) received a 30-minute directional, reasonably firm and rhythmic effleurage massage in the back in each of the three phases of labor. The control group (n=30), did not receive any form of massage and received a routine 30-minutes nursing care in each of the three phases. Measurements were then made for strength, interval and frequency of contractions and the duration of each phase. Data were analyzed using student t, Chi-square and Mann-Whitney tests. Results: Findings showed a significant decrease in the duration of labor after massage sessions. The mean duration of labor for the massage group was 5.75 hourse and for the routine nursing care group 9.15 houres (p=0.001). Conclusion: According to the above results, there was a significant decrease in duration of the first phase of labor in pregnant women receiving massage sessions. Therefore, this method can be used to decrease the period of hospitalization.

Abstract
Introduction: Labor refers to the chain of physiologic events that allows a fetus to undertake its journey from the uterus to the outside world. 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<0.05). But there was no relationship between the second stage and induction. The mean time of active phase and the second stage in this study was significantly higher than women of Freidman study (3.56 hours in contrast to 2.2 hours and 25 minute in contrast to 18 minute, respectively)(p<0.001). Also in the present study the deceleration phase was not seen. Conclusion: Now the pattern of labor progression differs from Freidman's curve in 1950 and has not the sigmoid shape, and the most important factor affecting latent phase is the dilatation of cervix at the time of admission. So determining a standard curve, without bias, is very difficult, and statistical methods should be used to decrease the effect of confounding factors of participants.
