This prospective observational cohort study aims to investigate the association between maternal musculoskeletal factors of the hip, lumbopelvic, abdominal, and pelvic floor regions and childbirth outcomes, as well as their consequences on pelvic floor function during the postpartum period. A total of 376 pregnant women will be recruited at 36 weeks of gestation and followed until 12 weeks postpartum. Musculoskeletal assessments will include hip range of motion, lumbopelvic mobility, abdominal muscle function, and pelvic floor strength and morphology. Obstetric outcomes such as mode of delivery and perineal trauma will be recorded after childbirth. The study will analyze whether maternal musculoskeletal function during late pregnancy is associated with delivery mode and pelvic floor dysfunction in the postpartum period.
