The foot of a pregnant woman undergoes morphological changes with the advancement of pregnancy. It is important to understand the structural changes of the foot during pregnancy and postpartum because any such change may alter the plantar pressure pattern and the entire foot biomechanics.
Primigravidae with a gestational age of 12 weeks or less, aged between 18 and 35 years were included in the study. They were prospectively studied across 5 time periods during pregnancy and postpartum. The measures recorded were length, width, navicular height, truncated foot length and normalized navicular height, truncated ratio of the foot, and the static plantar pressure pattern. Repeated-measures ANOVA was done to analyze the changes across various time periods.
All the foot parameters, except foot length and truncated foot length, showed significant differences across various time periods of pregnancy and postpartum (P < .001). It was found that the static plantar pressures also varied significantly (P ≤ .001).The maximum pressure was recorded at the hindfoot of the dominant leg.
The feet of pregnant women tend to get pronated as pregnancy advances but do not reach baseline values even at 6 weeks postpartum. Pregnant women tend to bear more weight on the dominant foot with an increased static hindfoot pressure as pregnancy progresses.
Prognostic study, Level I: Prospective.
随着孕期进展，孕妇的足部会发生形态变化。了解孕期及产后足部的结构变化很重要，因为任何此类变化都可能改变足底压力模式和整个足部生物力学。
纳入孕周小于或等于12周、年龄在18至35岁之间的初产妇。对她们在孕期和产后的5个时间段进行前瞻性研究。记录的测量指标包括长度、宽度、舟骨高度、截断足长、归一化舟骨高度、足部截断比例以及静态足底压力模式。采用重复测量方差分析来分析不同时间段的变化。
除足长和截断足长外，所有足部参数在孕期和产后的不同时间段均显示出显著差异（P <.001）。发现静态足底压力也有显著变化（P ≤.001）。最大压力记录在优势侧下肢的后足。
随着孕期进展，孕妇的足部趋于旋前，但即使在产后6周也未恢复到基线值。随着孕期进展，孕妇倾向于在优势足上承受更多重量，后足静态压力增加。
