Abstract

Low back pain(LBP) is a significant problem in today's society, with lifetime incidence rate reported between 50% and 90%. Many factors associated with LBP are reported. Among the causes, aberrations of posture may play a role in the development of LBP. Many investigators have assessed the curvature of spine in standing posture. But whether LBP is associated with lumbar hyperlordosis or hypolordosis is controversial.

Objective of the study was to evaluate static standing posture aberrations in chronic and acute LBP patients in comparison with healthy individuals. The sample including 98 subjects recruited to the following three groups: acute, chronic and control. Lumbar lordosis, thoracic kyphosis, lumbosacral angle and center of gravity(C.O.G.) were measured using skeletal analysis system and balance scan.

Chronic LBP patients exhibited a decreased lumbar lordosis, thoracic kyphosis, lumbosacral angle and backward displacement of C.O.G. compared to control group. Acute LBP patients exhibited a decreased lumbar lordosis, lumbosacral angle, increased thoracic kyphosis, and backward displacement of C.O.G. compared to control group.

We concluded that initially the lumbar hyperlordosis may result in LBP and thoracic and lumbar hypolordosis followed.

Key Words: Low back pain, Posture, Lumbar lordosis, Thoracic kyphosis
