摘要:

背景:膝骨性关节炎患者屈膝肌力及伸膝肌力均有不同程度的下降,进而影响患者的平衡控制能力。
目的:探讨膝骨性关节炎患者动态平衡功能的变化特征。
方法:纳入22例膝骨性关节炎患者(膝骨性关节炎组)和20例健康正常人(正常组),应用动态平衡仪进行动态平衡能力测试,包括总体稳定指数、前后方向稳定指数和左右方向稳定指数;稳定性测试:包括完成稳定性测试全部随机目标跟踪的时间,平均方向控制能力和前、后、右、左、前右、前左、后右、后左8个方向上的控制能力。
结果与结论:膝骨性关节炎组在睁眼双足站立、闭眼双足站立状态下总体稳定指数、前后方向稳定指数、左右方向稳定指数均高于正常组(P < 0.01),平均方向控制能力、前方控制能力、后方控制能力、左方控制能力、后右方控制能力测试值低于正常组,而完成该测试所需时间明显增加(P < 0.01)。说明膝骨性关节炎患者动态平衡能力下降。

Abstract:

BACKGROUND: Patients with knee osteoarthritis have decreased knee muscle strength and knee extensor muscle strength thus affecting the balance control ability.
OBJECTIVE: To explore the change characteristics of dynamic balance ability in knee osteoarthritis patients.
METHODS: Twenty-two knee osteoarthritis patients (knee osteoarthritis group) and 20 healthy adults (control group) were included. The dynamic balance ability was tested with dynamic balance device. The stability index, anterior/posterior stability index and medial/lateral stability index were measured. In limits of stability test, we measured direction control performance, average direction control performance, forward 
direction control performance, back direction control performance, left direction control performance, right direction control performance, forward/left direction control performance, forward/right direction control performance, back/left direction control performance, back/right direction control performance and limits of stability time.
RESULTS AND CONCLUSION: The total instability index, anterior/posterior stability index and medial/lateral stability index with eyes open or closed while standing with feet in the knee osteoarthritis group were higher than those in the control group (P < 0.01), and the average direction control performance, forward direction control performance, back direction control performance, left direction control performance and right direction control performance were lower than those in the control group, but the time for accomplish the test was increased significantly (P < 0.01). The results indicated the dynamic balance ability of the knee osteoarthritis patients was decreased.
