Effectiveness of a prenatal pilates program on ligamentous laxity and joint hypermobility in pregnant women: a dual-center randomized controlled trial.

Background: Pregnancy-related anatomical and hormonal changes, including increased relaxin levels, may cause ligamentous laxity and joint hypermobility, while also contributing to decreased overall body mobility, potentially affecting functional stability. Pilates, focusing on core strength and postural control, is recommended during pregnancy, but its effects on ligamentous laxity and joint hypermobility have not been tested in a randomized controlled trial. This study aimed to investigate the effectiveness of a prenatal Pilates program on ligamentous laxity and joint hypermobility in pregnant women.
