The knee joint position sense of a control group of healthy women was compared with that of women diagnosed as having severe osteoarthritis (OA) of the knee. Movements monitored were multi-joint when weightbearing on one leg. All subjects completed two angle rematching tests on two separate test occasions, and the criterion and reproduction angles which lay in the range of 15-45 degrees knee flexion were recorded photographically on each occasion. The results showed that the OA group performed the rematching tests with less accuracy than the controls (p < 0.05). Additionally, the OA group displayed significantly higher average flexion error magnitudes than the controls. These results suggest that joint position sense is less accurate and may be systematically distorted during multi-joint movements of the affected legs of a high proportion of women with severe knee OA. They further suggest that to improve their functional performance, patients with knee OA probably require a carefully constructed sensorimotor rehabilitation programme in which pain, effusion and fatigue are minimised.
将一组健康女性的膝关节位置觉与被诊断患有重度膝关节骨关节炎（OA）的女性的膝关节位置觉进行了比较。监测的动作是单腿负重时的多关节动作。所有受试者在两个不同的测试场合完成了两次角度匹配测试，每次都对膝关节屈曲15至45度范围内的标准角度和再现角度进行拍照记录。结果显示，骨关节炎组在匹配测试中的准确性低于对照组（p < 0.05）。此外，骨关节炎组的平均屈曲误差幅度明显高于对照组。这些结果表明，在患有重度膝关节骨关节炎的高比例女性的患侧腿多关节运动过程中，关节位置觉不太准确且可能会系统性地扭曲。它们还进一步表明，为了改善其功能表现，膝关节骨关节炎患者可能需要精心制定的感觉运动康复计划，其中要尽量减少疼痛、积液和疲劳。
