Balance and locomotion are two main complex functions, which require intact and efficient neuromuscular and sensory systems, and their proper integration. In many studies the assumption of their dependence is present, and some rehabilitation approaches are based on it. Other papers undermine this assumption. Therefore the aim of this study was to examine the possible dependence between gait and balance in patients with neurological or sensory integration problems, which affected their balance.
75 patients (52 with neurological diseases, 23 with sensory integration problems) participated in the study. They underwent balance assessment on Kistler force plate in two conditions, six tests on a Balance Biodex System and instrumented gait analysis with VICON. The gait and balances parameters and indices, together with entropy and cyclograms were used for the analysis. Spearman correlation, multiple regression, cluster analysis, and discriminant analysis were used as analytical tools.
The analysis divided patients into 2 groups with 100% correctly classified cases. Some balance and gait measures are better in the first group, but some others in the second.
This finding confirms the hypothesis that there is no direct link between gait and balance deficits.
平衡和运动是两项主要的复杂功能，这需要完整且高效的神经肌肉和感觉系统，以及它们的恰当整合。在许多研究中存在它们相互依赖的假设，并且一些康复方法就是基于此。其他论文则对这一假设提出质疑。因此，本研究的目的是检查患有影响其平衡的神经或感觉整合问题的患者的步态与平衡之间可能存在的依赖性。
75名患者（52名患有神经疾病，23名患有感觉整合问题）参与了该研究。他们在两种情况下在奇石乐测力板上进行了平衡评估，在平衡 Biodex 系统上进行了六项测试，并使用 VICON 进行了仪器化步态分析。步态和平衡参数及指标，以及熵和周期图被用于分析。使用斯皮尔曼相关性、多元回归、聚类分析和判别分析作为分析工具。
分析将患者分为两组，病例分类正确率为100%。第一组的一些平衡和步态测量结果较好，但第二组的其他一些结果较好。
这一发现证实了步态与平衡缺陷之间没有直接联系这一假设。
