The risk of falls increases with age, particularly in patients with osteoarthritis (OA). We aimed to investigate the relationships of fall history and spatiotemporal parameters in patients with hip and knee OA. This cross-sectional study included 51 patients with hip or knee OA. Fall history over the past year was recorded, and the centre of pressure (COP) parameters of gait and standing were assessed using the FDM-T treadmill. Comparisons were made between the fall and non-fall groups. Compared with the non-fall group, the fall group exhibited significant posterior displacement of the COP intersection during gait (p = 0.001). In hip OA patients, significant age, anterior‒posterior symmetry, and variability differences were observed. In knee OA patients, anterior‒posterior symmetry and lateral variability showed significant between-group differences. This study revealed a significant association between posterior COP displacement during gait and fall history. This parameter may serve as a novel fall indicator. Further prospective studies are needed to determine its predictive value for fall prevention.
跌倒风险随年龄增长而增加，在骨关节炎（OA）患者中尤为如此。我们旨在研究髋部和膝部骨关节炎患者的跌倒史与时空参数之间的关系。这项横断面研究纳入了51例髋部或膝部骨关节炎患者。记录过去一年的跌倒史，并使用FDM-T跑步机评估步态和站立时的压力中心（COP）参数。对跌倒组和非跌倒组进行了比较。与非跌倒组相比，跌倒组在步态期间COP交叉点出现显著的向后位移（p = 0.001）。在髋部骨关节炎患者中，观察到显著的年龄、前后对称性和变异性差异。在膝部骨关节炎患者中，前后对称性和侧向变异性在组间显示出显著差异。本研究揭示了步态期间COP向后位移与跌倒史之间存在显著关联。该参数可能作为一种新的跌倒指标。需要进一步的前瞻性研究来确定其在预防跌倒方面的预测价值。
