Proper posture provides the best balance and body stability at minimal muscular effort. It is constantly controlled by the central nervous system, which integrates the stimuli from the proprioceptors (deep feeling sensors), vision receptors, and balance receptors through the subcortical structures. The main purpose of the study was to describe single stance stability and its correlation with the degree of scoliosis and trunk rotation among patients suffering from idiopathic scoliosis and in the control group without scoliosis. The study included 80 patients (69 girls and 11 boys) and 40 healthy children without scoliosis (21 girls and 19 boys). The Cobb angle technique was used to determine the magnitude of the deformity. All subjects were divided into three subgroups according to Bogdanov's classification. Single stance stability with eyes open and eyes closed was assessed with an electronic postural station-Delos Postural Proprioceptive System (DPPS). In case of multiple group comparisons for variables with normal distribution ANOVA with Scheffe, post hoc test was used or Kruskal-Wallis test was used as the nonparametric equivalent. The relationship between the two continuous variables was investigated using either Pearson product-moment correlation or Spearman's rank correlation. In all these calculations, the statistical significance level was set to < 0.05. The single stance test showed a significant difference between the stability index with eyes open and stability index with eyes closed in study and control groups. The character of these alterations is influenced by the degree of trunk rotation. The degree of scoliosis according to Bogdanov classification does not determine the decrease in stability indexes. In summary, significantly lower values of the stability index during one-leg standing with eyes closed indicated balance impairment, which is mainly connected with inadequate functioning of the proprioceptive system.
正确的姿势以最小的肌肉努力提供最佳的平衡和身体稳定性。它由中枢神经系统不断控制，该系统通过皮质下结构整合来自本体感受器（深部感觉传感器）、视觉感受器和平衡感受器的刺激。本研究的主要目的是描述特发性脊柱侧凸患者和无脊柱侧凸对照组单腿站立的稳定性及其与脊柱侧凸程度和躯干旋转的相关性。研究包括 80 名患者（69 名女孩和 11 名男孩）和 40 名无脊柱侧凸的健康儿童（21 名女孩和 19 名男孩）。Cobb 角技术用于确定畸形的程度。所有受试者均根据 Bogdanov 分类分为三组。睁眼和闭眼单腿站立稳定性采用电子姿势站-Delos 姿势本体感觉系统（DPPS）评估。对于具有正态分布的变量的多组比较，使用 ANOVA 与 Scheffe 后测检验，或使用 Kruskal-Wallis 检验作为非参数等效检验。使用 Pearson 积矩相关或 Spearman 等级相关研究两个连续变量之间的关系。在所有这些计算中，统计显著性水平均设为 < 0.05。研究组和对照组睁眼和闭眼单腿站立稳定性指数之间存在显著差异。这些变化的特征受躯干旋转程度的影响。根据 Bogdanov 分类的脊柱侧凸程度并不能确定稳定性指数的降低。总之，闭眼单腿站立时稳定性指数明显降低表明平衡受损，这主要与本体感觉系统功能不足有关。
