Care practice #2: freedom of movement throughout labor.

This updated edition of Care Practice Paper #2 presents the evidence for the benefits of allowing freedom of movement in labor. Physiologic and anatomical principles that support the benefits of movement are explained. The authors review common obstacles to movement in labor, including the routine use of interventions that inhibit women's ability to walk or change position. Women are encouraged to plan to be active in labor and to select care providers and birth settings that provide the full range of options for using movement in labor.
