This study characterized the center of pressure planar displacement by palindromic strings. The objective is to test if the center of pressure pathway of able-bodied girls and those with a moderate and severe scoliosis displayed similar palindromic tendencies. The center of pressure excursions of 21 able-bodied girls were compared to 14 girls with a moderate scoliosis and 14 girls with severe one. Each girl was asked to stand upright on a force platform for 64 s. A crisscross grid of nine areas was centered around the mean center of pressure position (G) to define three other zones to use the MATLAB built-in nucleotide sequence analysis function. These were the antero-posterior extremities A, the coronal extremities C and the tilted or the four corners of the crisscross grid, T. The center of pressure positions were associated to any of the 4 zones using the GATC acronym. For all groups center of pressure pattern in decreasing order was A, G, T and C. Able-bodied girls favored the A zones. Girls with moderate scoliosis displaced their center of pressure mostly in the A zones with shifts in the T sections ( ≤ 0.001). Girls with severe scoliosis, additionally displaced their center of pressure in the C zones (P ≤ 0.001). An ankle modality characterized able-bodied girl's standing balance. Girls with a moderate scoliosis privilege the palindromic zones in the antero-posterior extremities with excursions in the corners of the base of support, girls with severe scoliosis further relied on the medio-lateral zones, suggesting a wobbling standing balance.

压力中心回文揭示了脊柱侧弯女孩站立平衡的摇摆

这项研究通过回文弦来表征压力平面位移的中心。目的是测试身体健全的女孩和患有中度和重度脊柱侧弯的女孩的压力通路中心是否表现出相似的回文倾向。研究人员将 21 名身体健全的女孩的压力偏离中心与 14 名患有中度脊柱侧弯的女孩和 14 名患有严重脊柱侧弯的女孩进行了比较。每个女孩都被要求在力台上直立 64 秒。九个区域的纵横交错网格以平均压力中心位置 (G) 为中心，以定义其他三个区域以使用 MATLAB 内置核苷酸序列分析功能。这些是前后肢 A、冠状肢 C 和十字网格的倾斜角或四个角 T。压力位置中心使用 GATC 缩写与 4 个区域中的任何一个相关联。对于所有组别，压力中心依次为 A、G、T 和 C。身体健全的女孩更喜欢 A 区。患有中度脊柱侧弯的女孩的压力中心主要转移在 A 区，T 区发生转移（≤ 0.001）。患有严重脊柱侧弯的女孩的压力中心也转移到了 C 区（P ≤ 0.001）。脚踝形态体现了身体健全女孩的站立平衡能力。中度脊柱侧弯的女孩优先考虑四肢前后回文区，支撑底座的角落有偏移，严重脊柱侧弯的女孩则进一步依赖中外侧区，这表明站立平衡不稳定。
