Results: There are different definitions for regular duration of labor and prolonged first stage of labor. During the 20th century, the regular duration of labor bisected. The specific use of maternal labor positions during labor can support labor progress during a prolonged first stage of labor. Conclusion: Labor positions are alternative methods to support labor progress in prolonged labor and a possibility to avoid medical interventions.
