In a closed kinematic chain of action, reduced lumbar lordotic curvature will not occur during an anterior pelvic tilt
In a closed kinematic chain of actions when there is anterior pelvic tilt, the lordotic curvature will be increased.
Initially there is a change in the inclination of the iliosacral segment followed by increased lordosis. Consequently the fifth lumbar vertebra displacement occurs due to vertebral shearing force. The anterior longitudinal ligament is stretched because of the increased lordosis.
