Lumbar Lordosis in Asymptomatics Subjects and Patients with Chronic Low Back Pain

Introduction: The relationship between the degree of lumbar lordosis and chronic and purpose low back pain (LBP) has long been speculated , but there is discrepancy in findings of previous researchers. The purpose of this of this study was to determine differences between lumbar lordosis in asymptomatic and LBP subjects. Matherials: Lumbar lordosis of 420 patients with chronic LBP and 420 asymptomatic subjects was measured by two examiner. A flexible ruler was used to measure lumbar lodosis in all subjects. Results: The averagr degree of lumbar lordosis for all subjects was 37 ± 13°. Females had greater lumbar lordosis (42 ± 15°) than males (32 ± 10°) and elderly subjects had lesser lumbar lordosis than yonger and middle aged subjects. Conclussoion: The degree of lumbar lordosis was not differet between normal subjects and those with LBP. it seems that effects of lumbar lordosis on LBP and treatment programs need to be reevaluated.
