Effectiveness of a prenatal pilates program on ligamentous laxity and joint hypermobility in pregnant women: a dual-center randomized controlled trial.
Trial report in BMC pregnancy and childbirth, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06684002 (Investigation of the Effect of Pilates Exercises on Laxity in Pregnant Women), which is not on this map. Cited by 2 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
backgroundPregnancy-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.
methodsIn this prospectively registered, dual-center randomized controlled trial (ClinicalTrials.gov: NCT06684002), 42 healthy primiparous women at 14-16 weeks' gestation were randomized to an 8-week structured prenatal Pilates program (n = 21) or standard prenatal care without exercise (n = 21). The intervention was delivered by the same certified physiotherapist at both centers to ensure consistency. Outcomes included anterior cruciate ligamentous laxity measured with the GNRB arthrometer, generalized joint hypermobility using the Beighton score, and activity limitations due to pelvic girdle pain assessed by the Pelvic Girdle Questionnaire, evaluated at baseline, 4 weeks, and 8 weeks.
resultsParticipants in the Pilates group showed no significant changes in ligamentous laxity and joint hypermobility and reported minimal activity limitations throughout the intervention (p > 0.05). In contrast, the control group demonstrated significant deterioration across all outcomes (p < 0.05). After 8 weeks, the Pilates group demonstrated significant improvements compared to the control group, with medium effect sizes for ligamentous laxity (p < 0.05, ηp² ≥ 0.06), a small effect size for joint hypermobility (p = 0.017, ηp² = 0.039), and a large effect size for activity limitations due to pelvic girdle pain (p = 0.021, ηp² = 0.317).
conclusionsAn 8-week structured prenatal Pilates program appears to effectively prevent the progression of ligamentous laxity and joint hypermobility while reducing activity limitations associated with pelvic girdle pain, supporting its integration into routine prenatal care to enhance maternal musculoskeletal stability, functional capacity, and quality of life during pregnancy.
