lateral pelvic displacement, one of the five major kinetic determinants of gait. It helps to synchronize the rhythmic movements of walking and is produced by the horizontal shift of the pelvis or relative hip abduction. It is often a factor in the diagnosis and treatment of various orthopedic diseases, deformities, and abnormal conditions and in the analysis and correction of dysfunctional gaits. Compare knee-ankle interaction, knee-hip flexion, pelvic rotation, pelvic tilt.
