Lumbar Lordosis
Definition
The natural anterior convexity (inward curve) of the lumbar spine. Normal lumbar lordosis is approximately 40-60 degrees (Cobb angle). Excessive lordosis (hyperlordosis) is an exaggerated curve that compresses posterior spinal elements. Reduced lordosis (flat lumbar spine) increases anterior disc loading.
Clinical Significance
Lumbar lordosis is directly linked to pelvic tilt -- anterior pelvic tilt increases lordosis, posterior tilt decreases it. Excessive lordosis compresses facet joints and narrows the spinal canal posteriorly. Insufficient lordosis increases anterior disc compression. The lumbar curve adapts to the pelvis below and the thoracic spine above, making it a downstream indicator rather than a primary driver in most cases.
How AKMI Assesses This
AKMI measures lumbar lordosis through lateral postural analysis, correlating with pelvic tilt angle and thoracic kyphosis. The assessment determines whether lumbar position is driven by pelvic orientation, thoracic compensation, or intrinsic lumbar pathology.
