Abstract
: Low back pain (LBP) is a common musculoskeletal disorder influenced by spinal sagittal alignment, anthropometric characteristics, and occupational activity. Alterations in lumbar lordosis and associated lumbosacral angles have been implicated in the development and severity of LBP. This study aimed to assess the relationship between occupation, anthropometric factors, and lumbar sagittal alignment in patients with LBP.
Methods: A comparative cross-sectional study was conducted over two years at the Department of Anatomy, Index Medical College Hospital and Research Centre, Indore. The study included 110 participants: 55 patients with clinically diagnosed LBP and 55 age- and sex-matched healthy controls. Demographic, occupational, and anthropometric data were recorded. Lateral lumbosacral radiographs were acquired under standardized conditions and analyzed using RadiAnt DICOM Viewer software. Four sagittal alignment parameters—lumbar lordosis angle (LLA), lumbosacral angle (LSA), sacral inclination angle (SIA), and lumbosacral disc angle (LSDA)—were measured, and statistical analysis was performed to evaluate correlations and differences across occupational groups.
Results: Sedentary participants exhibited lower LLA and higher SIA compared to manual laborers and mixed-activity individuals, with significant differences observed for LLA (p = 0.029), SIA (p = 0.033), and LSDA (p = 0.041). Strong correlations were found among sagittal parameters: LLA negatively correlated with SIA (r = −0.62) and LSDA (r = −0.58) and positively with LSA (r = 0.46). The mean height, weight, and BMI of participants were 164.2 ± 7.8 cm, 67.5 ± 9.6 kg, and 24.9 ± 3.1 kg/m², respectively. Comparisons between housewives and working females revealed higher LLA and lower SIA in working females, highlighting the influence of occupational activity on spinal curvature.
Conclusion: Occupational type and anthropometric factors, particularly BMI, significantly affect lumbar sagittal alignment in patients with LBP. These findings underscore the importance of considering lifestyle, occupational activity, and body habitus when evaluating spinal biomechanics and developing preventive or therapeutic strategies for LBP.
