客观的。检验以下假设：1）膝部位置感随年龄增长而下降； 2）骨关节炎（OA）患者的膝关节位置感比老年人差； 3)膝关节位置感与功能状态的相关性。方法。对 30 名双膝 OA 患者（双膝 Kellgren/Lawrence 分级大于或等于 2 级）、29 名老年对照（符合排除 GA 的临床和放射学标准）和 25 名年轻对照进行了膝关节位移检测阈值的测量，还评估了运动范围、松弛、放射学严重程度和功能状态。 结果。关节位移检测阈值与年龄之间存在中度相关性（右膝和左膝分别为 r = 0.598 和 r = 0.501），OA 患者与老年对照之间的阈值存在显着差异，本体感觉障碍与较差的疾病特异性功能状态相关。结论。本体感觉随着年龄的增长而下降，并且在患有膝骨关节炎的老年患者中进一步受损。本体感觉差会导致膝关节骨关节炎的功能障碍。
Objective. To test the hypotheses that 1) knee position sense declines with age; 2) patients with osteoarthritis (OA) have worse knee position sense than elderly controls; and 3) knee position sense is correlated with functional status.Methods. The threshold for detection of knee joint displacement was measured in 30 patients with bilateral knee OA (Kellgren/Lawrence grade greater than or equal to 2 in both knees), 29 elderly controls (who met clinical and radiographic criteria for exclusion of GA), and 25,young controls, Range of motion, laxity, radiographic severity, and functional status were also assessed.Results. A moderate correlation was found between joint displacement detection threshold and age (r = 0.598 and r = 0.501 for the right knee and the left knee, respectively), The threshold was substantially and significantly different between the OA patients and the elderly controls, Proprioceptive impairment was associated with worse disease-specific functional status.Conclusion. Proprioception declines with age, and is further impaired in elderly patients with knee OA. Poor proprioception mag contribute to functional impairment in knee OA.
