Abstract


The changes of physiological and morphological during pregnancy muld lead to gait pattern's changes. The aim of this study was to analysis the variation of pregnancy gait balance. Sixteen healthy pregnant women by choosing were performed during the second and third trimesters and again post-partum. Novel EMED was used for measuring the trajectory of the centre of pressure (COP). The results revealed that COP deviation distance (Dn) significantly increase in third trimester compared with post-partum during the initial contact phase (P=0.038). No differences were observed in the deviation distance of trimesters and postpartum during the forefoot push off phase. This method and results maybe have a new sight to reveal the dynamic stability with advanced pregnancy.
