Spinal posture and mobility were studied in 71 girls with progressive adolescent idiopathic thoracic scoliosis. Measurements were carried out by inclinometers and a compass in three planes; sagittal, frontal, and horizontal. The patients were divided into three groups according to the curve magnitude. Group 1 had curves smaller than 25 degrees, group 2 had curves between 25 and 35 degrees, and group 3 had curves greater than 35 degrees. The positional inclines of sacrum, upper lumbar and upper thoracic areas became more vertical as the curve size increased resulting in smaller lumbar lordosis and thoracic kyphosis. In the thoracic spine flexion and bending to the right was smaller in group 3 than in the other groups. Rotations in both clockwise and counterclockwise directions decreased as the curve size increased. In the lumbar spine only bending to the left decreased significantly with the curve size increase. All thoracic and lumbar movements except lumbar rotations had a general tendency to stiffening as the curve size increased. Of the mobility measurements thoracic rotation most clearly decreased with increased curves, which together with straightening of the spine can be important features in the pathomechanism of a progressive idiopathic thoracic curve.
对71名患有进行性青少年特发性胸椎侧弯的女孩的脊柱姿势和活动度进行了研究。使用倾角仪和指南针在矢状面、额状面和水平面三个平面进行测量。根据侧弯程度将患者分为三组。第1组侧弯小于25度，第2组侧弯在25至35度之间，第3组侧弯大于35度。随着侧弯程度增加，骶骨、上腰椎和上胸部区域的位置倾斜变得更加垂直，导致腰椎前凸和胸椎后凸减小。在胸椎，第3组向右的前屈和侧屈小于其他组。随着侧弯程度增加，顺时针和逆时针方向的旋转均减少。在腰椎，仅向左的侧屈随着侧弯程度增加而显著减少。随着侧弯程度增加，除腰椎旋转外，所有胸椎和腰椎运动总体上都有僵硬的趋势。在活动度测量中，胸椎旋转随侧弯增加最明显减少，这与脊柱变直一起可能是进行性特发性胸椎侧弯发病机制中的重要特征。
