Design outcomes

Primary

MeasureTime frame
Pain intensity of labor. Timepoint: Measurement of pain score and pain intensity upon entering the study, then after intervention in cervical dilatations of 4-5, 7-6 and 8-9 cm. Method of measurement: Pain score and intensity will be measured through the visual analog pain scale tool and McGill short pain questionnaire.;Length of first stage of labor. Timepoint: The length of the first stage of labor will be measured by the universal partograph form. Method of measurement: The length of the first stage of labor will be calculated from the time the pregnant mother enters the active phase (at the time of entering the study) until the dilatation of 10 cm of the cervix.
