The effects of the lumbosacral Lumbostab orthosis on intervertebral mobility, spinal geometry, and the geometrical deformations of discs have been investigated with a three-dimensional (3-D) reconstruction technique of the lumbar spine. Positions studied are neutral standing, maximal flexion, extension, left lateral bending, and left axial rotation. Results from this preliminary study indicate that the orthosis has a tendency to reduce vertebral mobility and discal deformations mainly at the upper segments (L1-L3), while it seems to increase vertebral displacements and discal deformations at the lower levels.
采用腰椎三维（3-D）重建技术，研究了腰骶部Lumbostab矫形器对椎间活动度、脊柱几何形态以及椎间盘几何变形的影响。研究的体位包括中立位站立、最大前屈、后伸、左侧弯和左侧轴向旋转。这项初步研究的结果表明，该矫形器倾向于主要在腰椎上段（L1-L3）减少椎体活动度和椎间盘变形，而在腰椎下段似乎会增加椎体位移和椎间盘变形。
