Introduction[edit | edit source]
Lumbar joint is formed by wedge shaped IV disc anteriorly and posteriorly by L5-S1 facet.
Cailliet described a specific instance of coordinated, simultaneous activity of lumbar flexion and anterior tilting pf pelvis in sagittal plane during trunk flexion and extension.He combined lumbar and pelvic motion.[1]
When femur,pelvis and spine move in combined coordinated manner,it produces a larger ROM than what might be available to one segment alone.It is an open kinematic chain and is analogous to Scapulo-Humeral Rhythm.
What is lumbopelvic rhythm?[edit | edit source]
The activity of bending over to touch one's toes with knees straight depends on lumbopelvic rhythm.[2]
Lumbopelvic rhythm 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.
According to Cailliet[1] ,the first part of bending forward consists of lumbosacral flexion (FIG 1.A) followed by anterior tilting of pelvis at hip joints.(FIG 1.B). The muscles in the lower back namely erector spinae, contract eccentrically to control the movement against gravity while trunk flexes and pelvis. 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 hips, followed by extension of lumbar spine.[2]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 intrest include timing,as well as magnitude related characteristics.(FIG.3)
Lumbopelvic rhythm contribution to low back pain[edit | edit source]
While bending forward,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 can be enough to overload the muscles and this causes strain.During the reverse lumbopelvic rhythm,when the body is returning to the errect position,if the hip fexors are tight or the extensors are too weak to initiate posterior pelvic rotation , the spinal extensors can become overworked, causing injury and pain.(FIG.4)[3]
