What is the normal range for lumbar lordosis angle in adults?

The lumbar lordosis angle in adults typically falls within the range of 40 to 60 degrees. This curvature is an important anatomical feature that helps to support the weight of the upper body and maintain balance while standing and moving. A lordotic curve in the lumbar region plays a critical role in posture and spinal mechanics, allowing for proper distribution of forces along the spine during various activities.

Understanding this range is essential for healthcare professionals assessing spinal health, as deviations from the normal lumbar lordosis angle can indicate underlying issues, such as muscle imbalances or spinal disorders. Maintaining the lumbar lordosis within this normal range is crucial for optimal spinal function and biomechanics, influencing both mobility and overall physical health.
