What Is Lumbopelvic Rhythm?

Listen to this article

Lumbopelvic rhythm or the hip-spine coordination refers to the way in which the lumbar spine, moves in combination with the pelvis. It is the kinematic relationship between lumbar spine and hip joints during sagittal plane movement.The activity of bending over to touch one's toes with knees straight depends on lumbopelvic rhythm.

Lumbopelvic Rhythm

According to Cailliet, the first part of bending forward consists of lumbosacral flexion followed by anterior tilting of pelvis at hip joints . The muscles in the lower back namely erector spinae, contract eccentrically to control the movement against gravity while trunk flexes and pelvis tilts anteriorly. The muscles that flex the hip contract concentrically and this motion is balanced by eccentric contraction of muscles that extend the hip.

When return to the erect posture, this rhythm is reversed. It is initiated by posterior tilting of pelvis at the hip, followed by extension of lumbar spine. The hip extensors initiate the posterior rotation of the pelvis until it is in a better position for spinal extensors to concentrically contract without too much stress being put on them. As these muscles contract concentrically, the hip flexors contract eccentrically to help control the movement.The aspect of motion of interest include timing, as well as magnitude related characteristics.

Lumbopelvic Rhythm Contribution To Low Back Pain

Lumbopelvic rhythm while bending forward and returning to initial position has been investigated and better understanding of trunk motion pattern was achieved as used on research on low back disorders. During forward bending, the eccentric contractions of the lumbar and hip extensors help to lower the body in a controlled motion against gravity. If the muscles are weak or fatigued, the weight of the body is enough to overload the muscles and this causes strain. When the body is returning to the erect position, if the hip flexors are tight or the extensors are too weak to initiate posterior pelvic rotation, the spinal extensors can get overloaded, causing injury and pain.

Improvement Of Lumbopelvic Rhythm By Correction Of Forward Head Posture

Research was done on the improvement of lumbopelvic rhythm by correction of forward head posture which concluded that the study showed clinical significance in the improvement of lumbopelvic rhythm by forward head correction given for 4 weeks of treatment.

This included cervicothoracic fascia release, Maitland mobilisation, stretching of trapezius, pectorals, levator scapulae and neck exercise like chin tuck and chin drop.


  • It is used to identify 'Pelvic cross syndrome' in gymnasts.
  • It is used to identify weakness, inflexibilities or muscles imbalance which contribute to low back pain.
