Three-dimensional motion analysis of lumbopelvic rhythm during lateral trunk bending
[Purpose] To examine the variations in the lumbopelvic rhythm and lumbar-hip ratio in the frontal plane. [Subjects and Methods] Markers were placed on the T10 and T12 spinous processes, bilateral paravertebral muscles at the T11 level, the pelvis, and the femur. Lumbar spine and hip angles were measured during lateral trunk bending using three-dimensional motion analysis. Data from the trunk la...
متن کاملThree-Dimensional Motion Analysis of Lumbopelvic Rhythm During Trunk Extension
Hip-spine coordination, known as the lumbopelvic rhythm, can be expressed as the lumbar-hip ratio. The lumbopelvic rhythm and lumbar-hip ratio can be used to assess lower limb function. We clarified the lumbopelvic rhythm and lumbar-hip ratio during trunk extension. We established a novel set of marker positions for three-dimensional motion analysis to assess the lumbar spinal angle. The origin...
متن کاملThree-dimensional analysis of renal artery bending motion during respiration.
PURPOSE To evaluate displacement and bending of the renal arteries during respiration. METHODS Seven men (mean age 59+/-7 years, range 54-71) were imaged with contrast-enhanced magnetic resonance angiography (MRA). Two phases of the MRA were acquired during separate normal inspiration and expiration breath-holds. Displacement of the kidneys and renal ostia and changes in renal branch angle we...
متن کاملLumbopelvic rhythm during trunk motion in the sagittal plane: A review of the kinematic measurement methods and characterization approaches
Lumbopelvic rhythm during trunk forward bending and backward return has been widely investigated to have a better understanding of the pattern of trunk motion, as used in research on low back disorders. Considerable differences in the methods used to measure, and approaches used to characterize the lumbopelvic rhythm hinder the integration of findings of those studies for further research in th...
متن کاملRelaxation phenomenon in lumbar trunk muscles during lateral bending.
This paper reports myoelectric activity measurements in the lumbar trunk muscles when subjects performed tasks involving various degrees of lateral bending. Biomechanical model analyses were made to estimate the tensions in the lumbar trunk muscles required to perform those tasks. The tensions and the activity measurements were compared to see if a muscle relaxation phenomenon occurred. A relax...
