The primary purpose of this study was to analyse the relationship between 4 different methods of measuring the knee position sense of persons diagnosed as having osteoarthritis of the knee and position sense deficit with their disease severity. To this end, the active position sense of 8 patients was assessed in sitting using a potentiometer known to measure knee angles precisely. Also administered was a validated subjective questionnaire, the Lequesne algofunctional index. The measurements of position sense included: total reproduction error; mean absolute reproduction error; variability in algebraic error or variable error; and the average constant error of 5 angle reproduction tests. The total error, mean absolute error and constant error measurements were significantly correlated with the handicap scores on the questionnaire (p < 0.01). These results plus the further finding of a bias towards target underestimation in this group strongly suggests that impaired proprioception might be an important pathogenetic factor in determining the severity of this disabling disease.
本研究的主要目的是分析4种不同方法测量被诊断为膝关节骨关节炎患者的膝关节位置觉及其位置觉缺陷与疾病严重程度之间的关系。为此，使用已知能精确测量膝关节角度的电位计，对8名患者坐位时的主动位置觉进行评估。同时还发放了一份经过验证的主观问卷——勒凯纳功能疼痛指数。位置觉测量包括：总再现误差；平均绝对再现误差；代数误差或可变误差的变异性；以及5次角度再现测试的平均恒定误差。总误差、平均绝对误差和恒定误差测量结果与问卷上的残疾评分显著相关（p<0.01）。这些结果，再加上该组中存在目标低估偏差的进一步发现，强烈表明本体感觉受损可能是决定这种致残性疾病严重程度的一个重要致病因素。
