Abstract: This paper systematically searched Chinese and English databases from January 2000 to December 2024 to screen the research literature related to labor positions and biomechanics.By extracting key information such as study type, position type, measurement technique, mechanical parameters and injury findings, we focused on the differences in pelvic outlet expansion, lower limb joint loading and injury risk between upright and horizontal birthing positions, and then summarized the biomechanical mechanisms and findings by using thematic analysis.The analysis showed that the upright position could significantly expand the pelvic outlet, but might increase the load on the ankle and knee joints;the combination of video capture and open-source platform technology provided a new direction for the dynamic study of delivery positions.
