Although changes in the gait biomechanics during pregnancy are known to occur, it is unclear whether they return to their original state after childbirth. The objective of the current systematic review is to summarize existing literature reporting the biomechanical characteristics of gait in postpartum women and to identify knowledge gaps that calls for future investigations in this population. Relevant articles were selected using MEDLINE (PubMed), Scopus (Elsevier), Embase (Elsevier), and Web of Science (Clarivate Analytics). Articles were included if they met the following criteria: They must (1) include postpartum women, (2) report measures related to three-dimensional (3D) kinematics and/or kinetics, (3) have been published after 1990, and (4) have been published in English. The current systematic review included a total of 14 articles, five of which compare the data from postpartum women with nulliparous women or pre-pregnancy data. We observed that gait biomechanics changes of postpartum women could persist for more than 5 years after the childbirth. This review provides novel viewpoints on the biomechanics of postpartum women's gait and recommendations for future studies to fully understand these changes and improve postpartum women's physical and mental wellbeing.

产后与妊娠相关的步态生物力学适应是否恢复到孕前状态？：系统评价

尽管已知怀孕期间步态生物力学会发生变化，但尚不清楚分娩后是否会恢复到原始状态。当前系统评价的目的是总结报告产后妇女步态生物力学特征的现有文献，并确定需要对该人群进行未来调查的知识差距。使用 MEDLINE (PubMed)、Scopus (Elsevier)、Embase (Elsevier) 和 Web of Science (Clarivate Analytics) 选择相关文章。如果文章符合以下标准，则被纳入：它们必须 (1) 包括产后妇女，(2) 报告与三维 (3D) 运动学和/或动力学相关的测量结果，(3) 已于 1990 年之后发表，并且 (4 ）已以英文出版。目前的系统评价共包括 14 篇文章，其中 5 篇将产后妇女的数据与未产妇或怀孕前的数据进行了比较。我们观察到，产后女性的步态生物力学变化可以在产后持续5年以上。该综述为产后女性步态的生物力学提供了新颖的观点，并为未来的研究提供了建议，以充分了解这些变化并改善产后女性的身心健康。
