老年单、双膝痛骨关节炎患者的平衡功能及其跌倒风险对比分析

目的比较单膝痛和双膝痛骨关节炎老年患者的平衡功能特点及其跌倒风险。方法对30例老年无膝痛骨关节炎患者、30例老年单膝痛骨关节炎患者和32例老年双膝痛骨关节炎患者进行计时起立-行走测试(TUG)、静态姿势稳定性测试(PS)、动态姿势稳定极限性测试(LOS)以及动态跌倒风险测试(DFI)。结果单膝痛组TUG时间长于无膝痛组(P<0.05),双膝痛组明显长于无膝痛组(P<0.01),单、双膝痛组之间无显著性差异(P>0.05)。双膝痛组PS得分高于无膝痛组与单膝痛组(P<0.05),无膝痛组与单膝痛组之间无显著性差异(P>0.05)。双膝痛组的LOS完成时间明显长于无膝痛组和单膝痛组(P<0.01),无膝痛组与单膝痛组之间无显著性差异(P>0.05)。单、双膝痛组的DFI得分高于无膝痛组(P<0.05),双膝痛组高于单膝痛组(P<0.05)。结论老年单膝痛骨关节炎患者动态平衡功能的下降,存在高跌倒风险;老年双膝痛骨关节炎患者静态和动态平衡功能均下降,跌倒风险更高。

Balance Function and Falling Risk in Elderly Osteoarthritis Patients with Single or Double Knees Pain

Objective To explore the feature of balance function and falling risk in the elderly knee osteoarthritis patients with single knee pain or double knees pain.Methods 30 elderly knee osteoarthritis patients without pain,30 with single knee pain and 32 with double knees pain were tested with timed up and go test(TUG),postural stability(PS),limits of stability(LOS) and dynamic fall index(DFI).Results There was significant difference in the elderly between no pain and single or double knee pain(P<0.05) in TUG,but not between the single knee pain and double knees pain(P>0.05).There was no significant difference in the elderly between single knee pain and no pain(P>0.05) in PS,but was between double knees pain and the other 2 groups(P<0.05).There was significant difference between no pain and single or double knee pain(P<0.05) in LOS,but not between single knee pain and double knees pain(P>0.05).There was significant difference between no pain and single or double knee pain(P<0.05) in DFI,and between single knee pain and double knees pain(P<0.05).Conclusion The elderly osteoarthritis patients with single knee pain are in high falling risk with their dynamic balance injury,while those with double knees pain are in higher falling risk with their static and dynamic balance injury.
