Single group repeated measures with multiple raters.
To determine the inter-rater reliability of KT-1000 measurements of novice and experienced raters and to provide error estimates for these raters.
The KT-1000 arthrometer is often used clinically to quantify anterior tibial displacement. Few data have been documented, however, about the relative reliability of KT-1000 measurements obtained by novice compared with experienced users.
Two novice and two experienced KT-1000 users performed measurements on 29 knees of 25 patients after anterior cruciate ligament (ACL) reconstruction or with a diagnosis of ACL deficiency. Measurements were performed at 131 N. Interrater and intertrial reliability coefficients (interclass correlation coefficient; ICC) and the standard error of measurement were calculated for expert and novice raters.
The interrater ICC for novices was 0.65 and the interrate error was +/- 3.52 mm (90% confidence interval [CI]). The interrater ICC for experts was 0.79 and the interrater error was +/- 2.94 mm (90% CI).
These results suggest that experience in using the KT-1000 is related to the interrater error of measurements and that training is an important consideration when using the KT-1000 arthrometer.
单组重复测量,多评估者参与。
确定新手和经验丰富的评估者对KT - 1000测量结果的评估者间信度,并为这些评估者提供误差估计。
KT - 1000关节测量仪在临床上常用于量化胫骨前移。然而,与经验丰富的使用者相比,关于新手使用KT - 1000测量结果的相对可靠性的记录数据很少。
两名新手和两名经验丰富的KT - 1000使用者对25例患者的29个膝关节进行测量,这些患者均接受了前交叉韧带(ACL)重建或被诊断为ACL缺损。测量在131 N的力下进行。计算了专家和新手评估者的评估者间信度系数(组内相关系数;ICC)和测量标准误差。
新手评估者间的ICC为0.65,评估者间误差为±3.52 mm(90%置信区间[CI])。专家评估者间的ICC为0.79,评估者间误差为±2.94 mm(90% CI)。
这些结果表明,使用KT - 1000的经验与测量的评估者间误差有关,并且在使用KT - 1000关节测量仪时,培训是一个重要的考虑因素。
