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. •Gait biomechanics differ between postpartum and nulliparous women.•Postpartum women experience persistent alterations in gait even after 5 years.•Smaller gluteus maximus activity is seen in postpartum women.•Postpartum women show greater hip peak adduction moment.
