The 6-item Foot Posture Index (FPI-6) is a reliable tool for the evaluation of foot deformities. Our aim was to translate and cross-culturally validate the FPI-6 for use in French-speaking countries and to determine the intra-rater and inter-rater reliability of the French version.
Cross-cultural adaptation was performed according to guidelines. Two clinicians assessed the FPI-6 in 52 asymptomatic individuals. We evaluated intra- and inter-rater reliability with the intraclass correlation coefficients (ICC), correlations (p-value < 0.05) and Bland-Altman plots. Standard error of measurement (SEM) and minimum detectable change (MDC) were determined.
For the cross-cultural adaptation, we modified several items of the FPI-6 user guide and added footnotes to ensure correct interpretation. ICC of the total FPI-6 scores were 0.94 to 0.96 for the intra- and inter-rater reliability for dominant and non-dominant lower limb. Correlations were significant ( < 0.001); r 0.88 to 0.92. Total score SEM was 0.68 to 0.78 and MDC was 1.58 to 1.82.
Intra- and inter-rater reliability of this French version of the FPI-6 was excellent for the total score and good to excellent for each item. The French FPI-6 can be used in French-speaking countries. The identification of SEM and MDC scores is useful for clinical interpretation.
6 项足部姿势指数（FPI-6）是评估足部畸形的可靠工具。我们的目的是将 FPI-6 翻译并跨文化验证为法语国家使用，并确定法语版本的内部和外部评分者可靠性。
根据指南进行跨文化适应。两名临床医生评估了 52 名无症状个体的 FPI-6。我们使用组内相关系数（ICC）、相关性（p 值<0.05）和 Bland-Altman 图评估内部和外部评分者可靠性。还确定了测量标准误差（SEM）和最小可检测变化（MDC）。
对于跨文化适应，我们修改了 FPI-6 用户指南的几个项目，并添加了脚注以确保正确解释。优势和非优势下肢的 FPI-6 总分的 ICC 为 0.94 至 0.96。相关性具有统计学意义（<0.001）；r 值为 0.88 至 0.92。总分的 SEM 为 0.68 至 0.78，MDC 为 1.58 至 1.82。
该法语版 FPI-6 的总分内部和外部评分者可靠性非常好，每个项目的可靠性为好至非常好。法语 FPI-6 可用于法语国家。识别 SEM 和 MDC 分数对于临床解释很有用。
