This one blind clinical trial study was performed on 370 nulliparous mothers in Talesh Shahid Nooraani hospital in 2011.

Data collection tool was a checklist including the characteristics of the subjects، Partograph form and assessment of first، second & third stages of labor. Data was analyzed using SPSS software (version 13) and t-test and chi -square test. P < 0. 05 was considered significant. Length of first and second stages of labor between two groups had statistically significant difference (P<0. 001). Length of first and second stages of labor was longer in physiological delivery group than traditional group، but length of third stage of labor was not statistically significant between two groups (P<0. 72). The results showed that the method of physiological delivery can increase the length of labor.
