Postural stability is essential for functional independence in the pregnant population. The contradictions between existing studies and the lack of consistent characteristics in the strategies used by pregnant women for postural control demonstrate the need for further investigation.
The aim was to review the available literature on postural strategies throughout pregnancy in both static and dynamic conditions and to provide an assessment of the quality of these studies in terms of methodological issues to identify the reasons for the inconsistencies in findings between research centers.
Literature searches were conducted using PubMed and EBSCOhost Research Databases. The latest search was performed on September 01, 2024. The review was restricted to longitudinal, cross-sectional, case-control, and descriptive studies focused on the effect of pregnancy on the stability of future mothers, with the following criteria: healthy pregnant women and singleton pregnancies. Trials were excluded if they were restricted to multiple pregnancies or considered various kinds of interventions. The methodological quality was evaluated using the criteria proposed by Downs and Black. Data items such as information on study design, characteristics of the study sample, equipment used, stability task performance, and outcome measures were presented.
The final analysis comprised 22 articles, including a total of 641 pregnant and 296 nonpregnant women. Research results in both static and dynamic conditions are inconclusive, showing either a decrease, no change, or improvement in postural equilibrium as pregnancy advances. Importantly, the results indicate that women in advanced pregnancy may be at increased risk of falling when their vision is compromised.
A lack of homogeneity in the study groups and a small number of longitudinal analyses were observed. The methodologies applied and the postural indices used to measure body sway varied across the studies. Our findings can serve as basic data for health promotion programs to encourage safe daily activities in pregnant women.
姿势稳定性对于孕妇的功能独立性至关重要。现有研究之间的矛盾以及孕妇用于姿势控制的策略缺乏一致特征，表明有必要进行进一步调查。
旨在回顾关于孕期在静态和动态条件下姿势策略的现有文献，并根据方法学问题对这些研究的质量进行评估，以确定研究中心之间结果不一致的原因。
使用PubMed和EBSCOhost研究数据库进行文献检索。最近一次检索于2024年9月1日进行。该综述仅限于纵向、横断面、病例对照和描述性研究，重点关注怀孕对未来母亲稳定性的影响，标准如下：健康孕妇和单胎妊娠。如果试验仅限于多胎妊娠或考虑各种干预措施，则将其排除。使用唐斯和布莱克提出的标准评估方法学质量。呈现了诸如研究设计信息、研究样本特征、使用的设备、稳定性任务表现和结果测量等数据项。
最终分析包括22篇文章，共纳入641名孕妇和296名非孕妇。静态和动态条件下的研究结果都没有定论，随着孕期进展，姿势平衡显示出下降、无变化或改善。重要的是，结果表明，妊娠晚期的女性在视力受损时跌倒风险可能会增加。
观察到研究组缺乏同质性，纵向分析数量较少。各项研究应用的方法和用于测量身体摇摆的姿势指标各不相同。我们的研究结果可为促进健康计划提供基础数据，以鼓励孕妇进行安全的日常活动。
