• Description:
  Frequent trunk bending/return in the sagittal plane has been suggested as a risk factor for low back pain (LBP). The trunk motion in the sagittal plane is the result of flexion/extension of lumbar spine and rotation of pelvis. The relative pattern of lumbar and pelvic contributions to trunk motion has been studied under the so-called topic of lumbopelvic rhythm, which includes both magnitude and timing aspects of lumbar and pelvic contributions to trunk motion. We have previously shown that the magnitude of lumbar (pelvic) contribution to trunk motion is smaller (larger) in individuals older versus younger than 50 years old. But, there has not been any study yet to compare the timing aspect of lumbopelvic rhythm between the age groups. The mean absolute relative phase (MARP) between the thorax (i.e., sum of lumbar flexion/extension and pelvic rotation) and pelvis rotations was evaluated in this study to establish age-related differences in timing aspect of lumbopelvic rhythm among healthy individuals.
