目的 研究等速测试系统评定膝关节位置觉的重复测试信度和不同测试者间测试信度.方法 应用Biodex System 3型等速系统测试16例健康志愿者双侧膝关节位置觉(采用被动角度重建测试法),选择屈膝30°、45°和60°为目标角度,记录受试者实际角度与目标角度间的差值绝对值(误差角).由2名测试者负责重复测试和不同测试者间重复测试,前、后2次测试中间间隔3d.结果 受试者屈膝30°、45°和60°时,其误差角的重复测试信度组内相关系数(ICC)分别为0.728、0.780和0.807,不同测试者间信度Pearson相关系数分别为0.676、0.610和0.705,提示均具有显著相关性(P＜0.05).通过单因素方差分析发现受试者双膝、前后2次测试时各目标角度误差角间差异均无统计学意义(P＞0.05),所有受试者角度重建时误差角的95％可信区间上限均＜3°.结论 采用等速系统评定受试者膝关节位置觉具有较好的重复测试信度,在屈膝30 ～60°范围内选择1个目标角度测试即可,当受试者膝关节角度重建误差角＞3 a时应考虑其临床意义.

Objective To determine the intra-and inter-tester reliability of a dynamometer in assessment of knee joint position senses (JPS).Methods Sixteen healthy volunteers (intra-rater N =6,inter-rater N =10) were examined with regard to intra-and inter-tester reliability of knee JPS by using Biodex System 3 dynamometer,measured by passive replication test,with subjects passively returning to the initial positions at 30°,45° and 60° knee flexion.The absolute error (AE) angle was recorded.Both intra-and inter-tester reliability studies involved two testers.Results The intra-tester reliability of the AE were moderate reliable at 30°,45°and 60° knee flexion,and the values of intra-class correlation coefficients (ICC) were 0.728,0.780 and 0.807,respectively.The values of Pearson's correlation coefficients for inter-tester reliability were 0.676,0.610 and 0.705,respectively (P ＜ 0.05).There was no significant difference between the AE values of dominance and non-dominant knees,test and retest,and in the AE values of 30°,45°and 60° knee flexion (P ＞ 0.05).The 95％ confidence upper limits of all subjects' AE values were less than 3°.Conclusion The major findings of this study suggest that the test-retest reliability of the knee JPS were moderate using Biodex System 3 dynamometer,and selecting a target angle of passive replication test can achieve the same purpose in 30° to 60°knee flexion.The clinical significance should be taken into consideration when the AE changes were greater than 3 degrees.
