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 . 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.

特发性脊柱侧凸患者单足支持期间的姿势控制指标。

正确的姿势以最小的肌肉力量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，中枢神经系统通过皮层下结构整合来自本体感受器（深度感觉传感器），视觉感受器和平衡感受器的刺激。这项研究的主要目的是描述特发性脊柱侧弯患者和没有脊柱侧弯的对照组的单姿态稳定性及其与脊柱侧弯和躯干旋转程度的相关性。该研究包括80位患者（69位女孩和11位男孩）和40位无脊柱侧弯的健康儿童（21位女孩和19位男孩）。柯布角技术用于确定畸形的大小。根据Bogdanov的分类，将所有受试者分为三个亚组。使用电子姿势工作站Delos姿势本体感受系统（DPPS）评估睁眼和闭眼时的单姿势稳定性。如果对具有Scheffe的具有正态分布ANOVA的变量进行多组比较，则使用事后检验或将Kruskal-Wallis检验用作非参数等效项。使用皮尔逊积矩相关性或斯皮尔曼等级相关性研究了两个连续变量之间的关系。在所有这些计算中，统计显着性水平设置为 使用皮尔逊积矩相关性或斯皮尔曼等级相关性研究了两个连续变量之间的关系。在所有这些计算中，统计显着性水平设置为 使用皮尔逊积矩相关性或斯皮尔曼等级相关性研究了两个连续变量之间的关系。在所有这些计算中，统计显着性水平设置为。单姿态试验显示，研究组和对照组的睁眼稳定性指数和闭眼稳定性指数之间存在显着差异。这些变化的特征受躯干旋转程度的影响。根据Bogdanov分类的脊柱侧弯程度不能决定稳定性指标的降低。总之，闭腿时单腿站立时稳定性指数的值明显较低表示平衡受损，这主要与本体感受系统的功能不足有关。
