Study Notes

Lumbopelvic rhythm refers to the relationship between the pelvis and lumbar spine during movement.
Ipsidirectional lumbopelvic rhythm involves the pelvis and lumbar spine rotating in the same direction, while contradirectional lumbopelvic rhythm involves them rotating in opposite directions.
Contradirectional lumbopelvic rhythm is used during walking to keep the supralumbar trunk stationary.
Pelvic-on-femoral osteokinematics in the sagittal plane involve anterior and posterior pelvic tilting.
Anterior pelvic tilt increases lumbar lordosis and allows for hip flexion, while posterior pelvic tilt reduces lumbar lordosis and flexes the lumbar spine.
Pelvic-on-femoral rotation in the frontal plane involves hip abduction and adduction, limited by natural limits of lateral bending in the lumbar spine and tightness in adductor muscles or pubofemoral ligament.
Pelvic-on-femoral rotation in the horizontal plane involves internal and external rotation of the support hip, limited by the small amount of axial rotation normally permitted in the lumbar spine.
The lumbar spine and trunk must follow the rotation of the pelvis for full expression of pelvic-on-femoral rotation.
The anatomic and kinematic linkage between the hip and lumbar spine is clinically relevant for evaluating and treating pain or movement dysfunction in this region of the body.
Pelvic-on-femoral osteokinematics can be restricted by natural limitations of movement within the lumbar spine and tightness in various muscles and ligaments.
