本研究旨在评估随着怀孕的进展，从椅子上站起来和向前行走的模式的变化。12名孕妇和10名未经产妇女被纳入本研究。在矢状面用数码摄像机对参与者进行录像，并使用图像分析软件识别附着在受试者身上的标记的坐标。孕妇站立时躯干屈曲角峰值较小，而站立时髋关节伸展角峰值较大。此外，峰值水平和垂直的质心速度较低，出现早，在孕妇比对照组。在上升过程中，孕妇阻尼的推进归因于子宫体积的增加，他们加强了在步态开始向前推进。为了确保安全的运动，孕妇不应该开始步态，直到达到一个稳定的站立位置后，上升。皇冠版权所有（C）2013由爱思唯尔有限公司出版。保留所有权利。
The present study aimed to assess the changes in the pattern of rising from a chair and walking forward as pregnancy progressed. Twelve pregnant women and 10 nulliparous women were included in this study. Participants were videotaped with a digital video camera in the sagittal plane, and the coordinates of the markers attached to the subjects were identified using image analysis software. The peak trunk-flexion angle in pregnant women during rising was smaller, but the hip-extension angle during the stance phase was larger than in controls. Also, the peak horizontal and vertical velocities of the center of mass were lower, and appeared earlier, in pregnant women than in controls. During rising, pregnant women dampened the propulsion attributable to increased uterus volume, and they enhanced the forward propulsion at gait initiation. To ensure safe motion, pregnant women should not initiate gait until reaching a stable standing position after rising. Crown Copyright (C) 2013 Published by Elsevier Ltd. All rights reserved.
