    摘要:

    目的:探索双膝骨关节炎(KOA)对女性老年人“踝关节策略”动态平衡能力的影响。方法:采用德国Dr-Wolff公司生产的Balance-check动态平衡能力测试仪,对KOA患者和一般老年人进行 “踝关节策略”动态平衡能力实验测试与对比分析。结果:1)KOA组“踝关节策略”动态平衡能力得分低于对照组(P<0.01);2)KOA组的旋转速度和最大旋转速度与平衡得分等指标的相关性普遍偏弱,但是对照组的旋转速度和最大旋转速度与平衡得分等指标的相关性普遍较强;3)KOA组和对照组的平衡得分均与中心区时间%、水平中时间%、垂直中时间%呈正相关关系,与其他指标呈负相关关系。KOA组目标球在水平中、垂直中、中心区停留时间%均低于对照组;4)KOA组在水平方向上的动态平衡控制能力与对照组基本一致(P>0.05),但是在垂直方向上的动态平衡控制能力弱于对照组(P<0.01)。结论:1)双膝骨关节炎降低了女性老年人“踝关节策略”动态平衡能力。2)目标球在平衡板中心区停留时间是评估女性老年人“踝关节策略”动态平衡能力的有效指标。旋转速度和最大旋转速度仅可用于评估一般女性老年人的“踝关节策略”动态平衡能力,不能用于评估双KOA女性患者。3)双KOA不会影响女性老年人的左右对称平衡能力,但是会降低其前后对称平衡能力。这预示着双KOA女性老年人更容易向前或者向后跌倒,不容易发生侧向跌倒。

    Abstract:

    Objective: To test whether KOA can affect the regulation of ankle joint on the dynamic balance ability of the elderly female. Methods: The Balance-check dynamic balance tester produced by Dr-Wolff of Germany was used to test and compare the dynamic balance ability of the "ankle strategy" for KOA patients and the general elderly. Results: 1) The dynamic balance ability of KOA group is lower than that of control group (P <0.01); 2) The correlation between rotation speed, maximum rotation speed and balance score and other indicators of KOA group is generally weak, but the correlation between rotation speed, maximum rotation speed and balance score and other indicators of control group is generally strong;3) In KOA group and control group, the balance ability score is positively correlated with the central time percentage, the middle time percentage and the vertical time percentage, and negatively correlated with other indexes. The time percentage of KOA group is lower than control group in the horizontal, vertical and central area. The dynamic balance control ability of KOA group in the left and right direction is basically the same as control group (P>0.05), but the dynamic balance control ability in the vertical direction is weaker than control group (P<0.01). Conclusions: 1) Bilateral KOA reduces dynamic balance of "Ankle Strategy" in the elderly female; 2) The dwell time of the target ball in the center of the balance plate is an effective indicator for assessing the dynamic balance ability of the elderly female e elderly female, and cannot be used to evaluate patients with double KOA; 3)
