Comparison of the Modified Lumbar Pelvic Belt with the Current Belt on Low Back and Pelvic Pain in Pregnant Women

Abstract

Background: Low back pain is one of the most common problems for pregnant women during pregnancy. Most belts are designed for supporting the surface of the symphysis pubis or upper anterior iliac spine without any support in the lumbar region. Objective: This study aimed to compare the related effects between the new design and the current belt on the pain and function of pregnant women.Material and Methods: In this randomized control trial study, 48 pregnant women with pelvic and lumbar pain participated. The participants were randomly divided into three groups: current belt, modified belt, and control. Pain intensity assessment, pelvic girdle (PG), and Oswestry disability index (ODI) questionnaires were utilized at the beginning of the study and three weeks later. Results: The pain intensity decreased more in the modified belt group than in the current belt group. ODI and PG scores decreased in two belt groups after three weeks of follow-up. However, this decrease was greater in the modified belt group, there was no statistically significant difference. Conclusion: The disability decreased in both groups using the belts, and their function was improved. Accordingly, the use of a modified belt with lumbar and PG support can significantly reduce back and pelvic pain in pregnant women compared to the current pelvic belt.
