How Does the Lumbopelvic Complex Cope with the Obstetrical Load during Standing? Ergonomic Aspects of Body Posture in Pregnant Women

Pregnancy induces numerous modifications in the musculoskeletal system of female body. Since one essential roles lumbopelvic structure is to support mechanical loads upright position, this study was designed simulate response complex growing foetus pregnant women. The authors hypothesized that posture (i.e., lordosis and muscle involvement) under pregnancy conditions might be adjusted minimize demands obstetrical load. analysis load on during gestation made based numerical simulations carried out AnyBody Modeling System. pregnancy-related adjustments such as increased pelvic anteversion lumbar enhance reduction activation (e.g., erector spinae, transversus abdominis or iliopsoas), fatigue spinal (reaction force). results may help develop antenatal exercise programs targeting core strength stability.
