What is the effect of an anterior pelvic tilt on spinal curvature?

An anterior pelvic tilt significantly influences the curvature of the lumbar spine. When the pelvis tilts forward, it can cause the lumbar spine to assume a more exaggerated lordotic curve, leading to increased arching in the lower back. This change occurs because the tilt shifts the alignment of the pelvis in relation to the spine, prompting alterations in the distribution of forces along the vertebrae and resultant spinal curves.

As the pelvis tilts anteriorly, the lumbar vertebrae tend to extend more, contributing to heightened lumbar lordosis. This alteration can impact overall posture and may lead to discomfort or pain if not properly addressed, highlighting the importance of maintaining neutral pelvic positioning to support healthy spinal alignment. Understanding this relationship between pelvic position and spinal curvature is critical for professionals addressing postural issues and designing effective movement strategies.
