Abstract

Lee Cameron, Jonathan Marsden, Karen Watkins, Jenny Freeman

Pelvic girdle pain (PGP) occurs in 70% of pregnant women; of whom 25% have severe pain and 8% severe disability requiring the use of crutches, wheelchair or confinement to bed [1]. Patients with pregnancy related PGP have been shown to have increased pelvic joint motion compared with healthy pregnant controls, probably due to a combination of hormonal and biomechanical factors, leading to an increase in pelvic joint laxity, changes in lumbopelvic posture and increase in shearing forces through pelvic joints, thus leading to pain [2,3].
