During lumbar extension, which pelvic and hip motions occur?

Lumbar extension and the pelvis move together in a coordinated lumbopelvic rhythm. When you extend the lumbar spine, the pelvis tips anteriorly (nutation), increasing the lumbar lordosis. At the same time, the hips extend to help bring the trunk upright and maintain balance. Counternutation (posterior tilt) or hip flexion would oppose lumbar extension, so those combinations don’t fit. Thus, the movement pattern is pelvis nutation with hip extension.
