Despite the lack of evidence to support the efficacy of activity restriction, and newer data that highlight potential harms to the mother, the intervention is still prescribed. This review of the literature describes the potential benefits, harms, and efficacy of activity restriction in the prevention of preterm birth. © 2014 by Lippincott Williams & Wilkins.
