【目的】本研究旨在评估一种脚趾握力计的评定者内和评定者间信度。
【对象】研究对象为180名社区居民和20名大学生。
【方法】我们根据年龄将180人分为三组以确定评定者内信度。这三组分别为年轻人（年龄20 - 39岁）、中年人（年龄40 - 59岁）和老年人（年龄60 - 79岁）。以20名大学生为对象研究评定者间信度。我们计算组内相关系数来评估评定者内和评定者间信度。按性别对每组的评定者内信度进行评估。通过比较两名测试者的首次测量结果计算评定者间信度的组内相关系数。采用布兰德 - 奥特曼分析评估固定偏差和比例偏差。
【结果】评定者内信度在男性中显示出高度到几乎完全一致，在女性中显示出几乎完全一致。对于评定者内信度，大多数测量中发现有固定偏差，但完全没有发现比例偏差。评定者间信度显示出几乎完全一致。评定者间信度未发现固定偏差和比例偏差。
【结论】脚趾握力计的评定者内和评定者间信度较高，表明其适合临床使用。
[Purpose] The aim of this study was to evaluate the intrarater and interrater reliabilities of a toe grip dynamometer. [Subjects] The subjects were 180 community-dwelling people and 20 university students. [Methods] We assigned 180 individuals to three groups based on age to determine the intrarater reliability. The groups consisted of young (age, 20 to 39 y), middle-aged (age, 40 to 59 y) and older adults (age, 60 to 79 y). Interrater reliability was investigated using 20 university students as subjects. We calculated intraclass correlation coefficients to assess the intrarater and the interrater reliability. The intrarater reliability was assessed for each group by gender. We calculated intraclass correlation coefficients for the interrater reliability by comparing the first measurements made by two testers. The Bland-Altman analysis was used to assess fixed and proportional bias. [Results] The intrarater reliability showed a substantial to almost perfect agreement in male and almost perfect agreement in female subjects. For the intrarater reliability, a fixed bias was found in most measurements, but proportional bias was not found at all. The interrater reliability showed almost perfect agreement. Fixed bias and proportional bias were not found for the interrater reliability. [Conclusion] The intrarater and the interrater reliabilities of the toe grip dynamometer were substantial, indicating its suitability for clinical use.
