Proprioceptive, Fear-related and Inflammatory Factors in the Persistence of Pregnancy-related Lumbopelvic Pain.

Sponsor: Hasselt University

Summary

Pregnancy-related lumbopelvic pain (PLPP) affects 50-90% of pregnant women and is often dismissed as a normal part of pregnancy. However, the long-term consequences can be dramatic. Up to 21% of women with PLPP still have pain three years postpartum, and 10% experience disability, poorer quality of life, and lower ability to work 11 years after delivery. Because the multifactorial etiology of PLPP is unclear, prevention and treatment fall short. Previous studies on the causes of PLPP focused on impairments in motor output but ignored that impairments in sensory input (e.g., proprioception, the primary expertise of our research group) often precede motor output problems. Moreover, though psychological factors such as fear (of movement) are known to affect PLPP, their predictive role in PLPP remains understudied. Finally, the role of systemic inflammation in PLPP has yet to be examined, despite recent studies demonstrating its role in the chronification of lumbopelvic pain in the general population. This prospective cohort study aims to identify new modifiable predictors for the onset of PLPP during pregnancy and its persistence postpartum. The investigators will compare sensory (proprioception, body perception), fear-related, and inflammatory factors between women with and without PLPP and determine their predictive role in the onset and persistence of PLPP. The results will increase our understanding of the multifactorial etiology of PLPP and help optimize prevention and treatment.
