Abstract

Objectives Low back pain (LBP) is a major health problem affecting the adult population. Postural changes are one of the risk factor in some cases. Abnormal posture makes a strain on ligaments and muscules that indirectly affects the curvature of lumbal spine. The purpose of this study was to investigate the relationship between the angles of lumbar spine and spinal mobility in acute and chronic LBP patients.

Methods Fifty patients (25 female, 25 male) with chronic Low Back Pain (CLBP) and fifty patients (30 female, 20 male) with acute low back pain (ALBP) were included the study. Both groups were subjected to lumbosacral radiography in lateral position while they were standing. Measurements were made directly from the radiographs. Patients were assessed by parameters such as spinal mobility, sacral inclination angle, lumbosacral angle and sacral horizontal angle. Spinal mobility included lumbar spinal flexion and extension and measured by double inclinometer method.

Results There were no statistical differences between age and gender in both groups (p > 0.05). The value of the SIA was significantly increased in CLBP patients compared to ALBP group. It was also correlated with lumbar extension in CLBP patients (p < 0.005). There was no statistical difference in LSA between ALBP and CLBP groups (p > 0.05). There was also no observable difference between two groups and no correlation with lomber flexion and extension for men and women (p > 0.05).

Conclusion The weakness of these muscles may cause a forward posture and an increase in lumbar lordosis. Additional researches should be helpful to confirm the relationship between the angles of lumbar spine and low back pain.
