Kinematic analysis to elucidate postural control mechanism from rise up to gait initiation during pregnancy

目前的研究旨在评估孕妇在怀孕期间从椅子上站起来、向前走的姿势和模式的变化。体位变化存在较大的个体差异。孕妇站起来时躯干轻微弯曲，在怀孕早期，她们从椅子上站起来并达到稳定的站立姿势后开始走路。在整个妊娠期，她们在步态开始时通过大踢腿来增强向前推进力，但在妊娠中后期步态开始后，她们的姿势变得不稳定。

The present study aimed to assess the change in the posture and pattern of rising from a chair and walking forward as pregnancy progressed. There were great individual differences in the postural change. Pregnant women rose up with the small trunk flexion, and they initiated gait after rising from a chair and reaching a stable standing position during early pregnancy. They enhanced the propulsion forward at gait initiation by large kick out throughout gestational period, but their posture became unstable after gait initiation in mid to late pregnancy.
