20.500.12556/DiRROS-30165 Pregnancy-related pelvic girdle pain affects balance in the second and third trimesters of pregnancy Introduction: During pregnancy, many changes in the musculoskeletal system and pregnancy-related disorders affect posture and postural stability. Pregnancy-related pelvic girdle pain (PPGP) is a common disorder in pregnancy; the cause remains unknown. The purpose of the present study was to determine if PPGP affects static postural stability and its relation to the stage of pregnancy. Methods: Sixty-three pregnant women between the ages of 18 and 45 and between the 12th and 38th weeks of gestation were included in the study. They were divided into four groups according on the trimester and the presence of PPGP. Static balance was assessed using a force plate on firm and compliant surfaces with eyes open and closed. Results: Pregnant women with PPGP had significantly (p < 0.05) greater centre-of-pressure velocity and sway area compared to pregnant women without PPGP, especially in the third trimester of pregnancy. In the second trimester, only two significant differences in COP parameters were observed between pregnant women with and without PPGP. Pregnant women in the third trimester of pregnancy had significantly (p < 0.05) greater centre-of-pressure velocity and larger postural sway area compared to pregnant women in the second trimester of pregnancy, regardless of PPGP. Discussion and conclusion: Pregnant women with PPGP had poorer static stability when compared to pregnant women without pain, especially in the third trimester of pregnancy. The cause could be found in the poorer ability to stabilise the trunk and pelvis, poorer proprioception, and issues with automatic movement patterns. pregnancy pelvic third trimesters of pregnancy true false true Angleški jezik Ni določen Neznano 2026-06-16 12:07:37 2026-06-16 12:07:37 2026-07-02 12:12:45 0000-00-00 00:00:00 2024 0 0 Nasl. z nasl. zaslona; Opis vira z dne 20. 5. 2024; str. 1-11 no. 3, [article no.] e0287221 Vol. 19 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 618.1 1932-6203 10.1371/journal.pone.0287221 195984387 RAZ_Hrvatin_Ivana_2024.pdf RAZ_Hrvatin_Ivana_2024.pdf 1 3206CDBE636709AEE2053393C0A0A486 b3dde4ff9fb3fc716d64f467474fd297f5c58a07ecc62d694f9e60b421b13b92 4b624a29-696b-11f1-97b2-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45643 https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0287221 1 3586b4cb-696b-11f1-97b2-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=45642 Univerzitetni klinični center Ljubljana 0 0 0
