The aim of this study was to determine whether the differences in timing of the peak growth velocity (PGV) between sitting height, total body height, subischial leg length, and foot length can be used to predict whether the individual patient with adolescent idiopathic scoliosis is before or past his or her PGV of sitting height. Furthermore, ratios of growth of different body parts were considered in order to determine their value in prediction of the PGV of sitting height in the individual patient. Ages of the PGV were determined for sitting height (n=360), total body height (n=432), subischial leg length (n=357), and foot length (n=263), and compared for the whole group and for the individual child in particular. Furthermore, the ages of the highest and lowest ratios between the body length dimensions were determined and compared to the age of the PGV of sitting height. The mean ages of the highest and lowest ratios were significantly different from the mean age of the PGV of sitting height in 3 out of 12 ratios in girls and 8 out of 12 ratios in boys. The variation over children was large and the ratios were too small, leading to a too large influence of measurement errors. The mean ages of the PGV all differed significantly from the mean age of the PGV of sitting height. However, the variation over individual children of the age differences in PGV between body dimensions was large, and the differences in timing of the PGV were not useful to predict whether the individual child is before or past his or her PGV of sitting height.
本研究旨在确定坐高、全身体高、下肢长和足长的最大生长速度（PGV）峰值出现时间的差异是否可用于预测特发性脊柱侧凸青少年患者的 PGV 是在其之前还是之后。此外，还考虑了不同身体部位生长比例，以确定其在预测个体患者坐高 PGV 方面的价值。确定了坐高（n=360）、全身体高（n=432）、下肢长（n=357）和足长（n=263）的 PGV 年龄，并对所有患者和个别患者进行了比较。此外，还确定了身体长度维度之间最高和最低比例的年龄，并与坐高 PGV 年龄进行了比较。在女孩中，12 个比值中有 3 个，男孩中有 12 个比值中的 8 个，最高和最低比值的平均年龄与坐高 PGV 的平均年龄显著不同。儿童之间的差异很大，且比值太小，导致测量误差的影响过大。所有 PGV 的平均年龄与坐高 PGV 的平均年龄显著不同。然而，个体儿童之间的 PGV 之间的年龄差异很大，PGV 出现时间的差异无法用于预测个体患者是在其坐高 PGV 之前还是之后。
