Abstract: (10 Views)
Background: Pelvic alignment and lumbar lordosis are key postural parameters routinely evaluated in orthopedic assessments of patients with low back pain. This study aimed to compare the degree of lumbar
lordosis and pelvic tilt between patients with non-specific chronic low back pain and asymptomatic individuals during knee flexion and hip extension tests.
Methods: In this cross-sectional comparative study, 124 participants aged 20 to 45 were recruited from Babol, Iran, including 62 patients with non-specific chronic low back pain and 62 asymptomatic controls. For each participant, the magnitude and angle of lumbar lordosis were measured in the prone position. Pelvic tilt and its angle were assessed in a relaxed standing posture, as well as immediately after performing active hip extension and active knee flexion exercises. Data were analyzed using SPSS version 23, with a significance level of p < 0.05.
Results: No significant differences were found between the chronic low back pain group and controls in the mean lumbar lordosis angle (prone position) or mean pelvic tilt (standing position) across all measurement conditions (p > 0.05). Additionally, neither pain duration nor pain severity in the patient group correlated significantly with lumbar lordosis or pelvic tilt values (p > 0.05).
Conclusion: The findings suggest that lumbar lordosis and pelvic tilt, measured in relaxed prone and standing postures as well as after hip extension and knee flexion tests, do not significantly differ between individuals with non-specific chronic low back pain and asymptomatic controls. These postural parameters may therefore have limited clinical utility in assessing this patient population.
