Postural and Lumbopelvic Control: Crucial Factors in the Functionality of Patients with Low Back Pain—A Descriptive Cross-Sectional Study

Background: Low back pain (LBP) is one of the most prevalent musculoskeletal disorders in adults worldwide. Alterations in postural and lumbopelvic control and functionality appear to be determining factors in its resolution. Methods: A cross-sectional study was performed. Patients with LBP were enrolled. Lumbar pain; postural control (PC), total area of the center of pressure (TACOP), and the velocity of the center of pressure (VCOP); lumbopelvic control (LPC); and functionality were evaluated. Statistical tests were implemented to determine differences between sex and age and correlation models among the variables. Results: Thirty adult patients with LBP were analyzed. A strong relationship was found between pain and functionality r = 0.64; p < 0.001. A moderate relationship was found between pain and TACOP r = 0.395; p = 0.031. A moderate relationship was observed between TACOP and functionality 0.413; p = 0.023 and between LPC and TACOP r = 0.416; p = 0.001. Conclusions: This study demonstrates the significant impact of LBP on postural control, lumbopelvic control, and functionality. These results highlight the importance of addressing postural and lumbopelvic control in LBP treatment. No significant differences based on gender and age were found, but all clinical variables differed significantly between the LBP and control groups, underscoring the unique impairments associated with LBP.
