Study Notes
Hip Joint and Movement
- The term "lumbopelvic rhythm" describes the rotation of the pelvis, and often the superimposed trunk, over relatively fixed femurs.
- The iliofemoral ligament limits hip abduction and extension, and to a lesser degree, external rotation.
- Femoral-on-pelvic hip osteokinematics is described by the motion of the femur moving on the pelvis.
- The hip joint is a type of ball-and-socket joint.
Lumbopelvic Rhythm
- During ipsidirectional lumbopelvic rhythm, the pelvis and lumbar spine move together in the same direction.
- The purpose of ipsidirectional lumbopelvic rhythm is to facilitate movement and reduce stress on the lumbar spine.
- Contradirectional lumbopelvic rhythm is used when the pelvis and lumbar spine move in opposite directions, such as during heavy lifting or bending.
- The sequence of lumbo-pelvic rhythm during trunk extension is lumbar spine extension, followed by pelvic rotation.
Hip Flexion
- The force-couple typically shown during hip flexion is between the iliopsoas and the tensor fasciae latae.
