Maintaining body balance is a complex function based on the information deriving from the vestibular, visual, and proprioceptive systems. The aim of the study was to evaluate quiet single stance stability in young adults with lumbar derangement syndrome (LDS) and in the control group of the healthy subjects. The second aim of this study was to determine whether pain intensity, degree of disability, and the level of physical activity can influence postural control in patients with LDS. It is important to underline that selecting a homogeneous group of LBP patients using, for example, mechanical diagnosis and therapy method and Quebec Task Force Classification, can result in an increased sensitivity of the study. The study included 126 subjects: 70 patients with LDS (37 women, 33 men) and the control group 56 healthy volunteers (36 women, 20 men). In case of multiple group comparisons for variables with normal distribution, ANOVA post hoc test was used or, as the nonparametric equivalent, Kruskal-Wallis test. In all these calculations, the statistical significance level was set to < 0.05. The stability index eyes open for the study group was 88.34 and for the control group 89.86. There was no significant difference in the level of postural control between the study and control groups ( > 0.05). The level of stability index eyes closed (SI EC) for the study group was 71.44 and for the control group 77.1. SI EC results showed significant differences in proprioceptive control during single leg stance between the study and control groups ( < 0.05). The level of pain intensity, the degree of disability, and physical activity level did not influence postural control in the study group with LDS. In summary, patients with LDS showed significantly worse proprioceptive control.
维持身体平衡是一个复杂的功能，基于来自前庭、视觉和本体感觉系统的信息。本研究的目的是评估年轻的腰椎紊乱综合征 (LDS) 患者和健康对照组在安静单腿站立时的稳定性。本研究的第二个目的是确定疼痛强度、残疾程度和身体活动水平是否会影响 LDS 患者的姿势控制。重要的是要强调，例如使用机械诊断和治疗方法以及魁北克任务分类选择具有同质性的 LBP 患者组可以提高研究的敏感性。该研究包括 126 名受试者：70 名 LDS 患者（37 名女性，33 名男性）和对照组 56 名健康志愿者（36 名女性，20 名男性）。对于具有正态分布的变量，进行了多组比较，使用方差分析后检验或非参数等效的 Kruskal-Wallis 检验。在所有这些计算中，统计显著性水平设置为 < 0.05。研究组睁眼的稳定性指数为 88.34，对照组为 89.86。研究组和对照组之间的姿势控制水平没有显著差异（> 0.05）。研究组闭眼的稳定性指数（SI EC）为 71.44，对照组为 77.1。SI EC 结果表明，研究组和对照组之间在单腿站立时的本体感觉控制方面存在显著差异（< 0.05）。疼痛强度水平、残疾程度和身体活动水平均未影响 LDS 患者的姿势控制。总之，LDS 患者的本体感觉控制明显较差。
