The objective of this study was to quantify the effect of degenerative joint change on the proprioceptive acuity of women with osteoarthritis (OA) of the knee. Middle-aged women with OA of the knee, age-matched healthy women, and younger healthy women were studied. Tests examined the ability of subjects to correctly reproduce knee angles in weightbearing and non-weightbearing situations. The knee angles were photographed and measured in degrees. The absolute error (AE) of each matching test was calculated and the mean AE of two tests was used as the criterion variable in a three-way analysis of variance (ANOVA). The relationship between the reproduction error and the osteoarthritic subjects' self-paced walking speed was also examined. Under both test conditions the AE of the osteoarthritic subjects was greater than that of the healthy subjects (p < .05). There was, however, no significant relationship between the AE measurements of the patients and their walking speed. These data indicate that while women with OA may have poorer proprioception than healthy controls, this impairment may not affect their walking ability.
本研究的目的是量化退行性关节变化对膝骨关节炎（OA）女性本体感觉敏锐度的影响。研究对象包括患有膝OA的中年女性、年龄匹配的健康女性以及年轻健康女性。测试考察了受试者在负重和非负重情况下正确重现膝关节角度的能力。拍摄膝关节角度并以度为单位进行测量。计算每次匹配测试的绝对误差（AE），并将两次测试的平均AE用作三因素方差分析（ANOVA）中的标准变量。还研究了重现误差与骨关节炎受试者自定步速之间的关系。在两种测试条件下，骨关节炎受试者的AE均大于健康受试者（p <.05）。然而，患者的AE测量值与其步行速度之间没有显著关系。这些数据表明，虽然患有OA的女性可能比健康对照者本体感觉更差，但这种损伤可能不会影响她们的行走能力。
