Maternal activity restriction in pregnancy and the prevention of preterm birth: an evidence-based review

Abstract

Activity restriction is one of the most common practices used for the prevention of preterm birth. 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.
