Young women had more pain than older women. Back pain starting during pregnancy may be a special entity and may have another origin than back pain not related to pregnancy. Manipulation keeps the segments of the pregnant woman's structure freely and normally movable. It permits a constant free flow of all body fluids and a normal venous supply to control function. During the second 6 weeks of pregnancy the growing fetus and expanding uterus often settle in the hollow of the sacrum and relief of nausea may be achieved.
Manipulation results in an easier pregnancy and an easier delivery.
The postpartum return of the mother to prepartum health is also expedited by manipulation. Manipulation has a part in the prevention and cure of toxemia's. It can be demonstrated that chiropractic care significantly reduces the mean labor time. There was significantly less likelihood of back labor when spinal manipulative therapy was administered during pregnancy. Regular adjustments can make pregnancy less stressful and delivery less uncomfortable.
