The purpose of this study was to investigate the hypothesis that a lumbar pad producing extension of the lumbar spine is of value in posture support seats for children with Duchenne muscular dystrophy. Our method was to establish whether or not an increase in lumbar lordosis produced any increase in resistance to static lateral curvature of the supine lumbar spine. Nine boys with Duchenne muscular dystrophy were studied at an age when they were about to go into a wheelchair or had recently become wheelchair mobile. In each case the child lay supine on low-friction material on an x-ray table while the spine was flexed first to the right and then to the left, with and without a lumbar pad, by a predetermined force. The degree of lateral curvature was measured from anteroposterior radiographs. While lateral forces were applied when the boys were supine rather than seated, the results failed to show a difference in curvature with or without the lumbar pad.
对于患有杜氏肌营养不良症的儿童，能使腰椎伸展的腰垫在姿势支撑座椅中具有价值。我们的方法是确定腰椎前凸增加是否会使仰卧位腰椎静态侧方弯曲的阻力增加。对9名患有杜氏肌营养不良症的男孩进行了研究，他们正处于即将使用轮椅或最近刚开始使用轮椅活动的年龄。在每种情况下，孩子仰卧在X光检查台上的低摩擦材料上，脊柱先向右然后向左弯曲，施加预定的力，分别在有和没有腰垫的情况下进行。从前后位X光片测量侧方弯曲的程度。虽然在男孩仰卧而非就座时施加侧方力，但结果未能显示有或没有腰垫时弯曲度存在差异。
