背景：自我报告问卷是确定踝关节不稳定个体的常用方法。最近的一项研究表明，单一使用任何一种最常用的问卷都无法显着预测脚踝稳定性状况。因此，本文的目的是介绍与功能性踝关节不稳定识别(IdFAI)发展相关的信息。方法：278例志愿者(男125例，女153例，年龄19.8±1.4岁)一次性完成IdFAI。以主轴因式分解为提取方法，采用VARIMAX旋转，进行探索性因子分析。此外，还进行了判别函数分析，以确定辨别分数并评估问卷的准确性。结果：因素分析显示：因素1(4个问题)解释了53.7%的变异，因素2(4个问题)解释了17.4%，因素3(2个问题)解释了6.3%。总体而言，这些因素解释了77.4%的差异。有一个明显的歧视分数为10.3，以确定谁拥有最低限度接受的标准的FM。总体而言，IdFAI的准确率为89.6%。结论：IdFAI是识别FAI个体的一种可行、合适的方法。临床意义：我们建议临床医生和研究人员使用IdFAI来识别功能性踝关节不稳定的个体，因为它是一个简短、简单、易于管理和使用的问卷，而且已被证明具有极好的准确性。
Background: Self-reported questionnaires are a common method used in identifying individuals with ankle instability. Recently a study illustrated the singular use of any of the most frequently utilized questionnaires failed to significantly predict ankle stability status. Therefore, the purpose of this article was to present information related to the development of the Identification of Functional Ankle Instability (IdFAI). Methods: Volunteers (n = 278; 125 males, 153 females, 19.8 +/- 1.4 years) completed the IdFAI on one occasion. An exploratory factor analysis was conducted with principal axis factoring as the extraction method with varimax rotation. Additionally, a discriminant function analysis was conducted to identify a discrimination score and to evaluate the accuracy of the questionnaire. Results: The factor analysis revealed: factor 1 (four questions) explained 53.7% of the variance, factor 2 (four questions) with an additional 17.4%, and factor 3 (two questions) an additional 6.3%. Overall, these factors accounted for 77.4% of the variance. There was a distinct discrimination score of 10.3 to identify people who have the minimally accepted criteria for FM. Overall, the IdFAI has an accuracy of 89.6%. Conclusion: This investigation showed that the IdFAI was a feasible and appropriate way to identify individuals with FAI. Clinical Relevance: We suggest clinicians and researchers utilize the IdFAI to identify individuals with functional ankle instability since it is a short, simple, easy questionnaire to administer and take, and has been shown to have excellent accuracy.
