BACKGROUND: Despite its wide use in clinical outcome measurement, there is yet no validated German language version of the @entity5363 available. After finishing cross-cultural adaption of the @entity5363 according to the AAOS guidelines, an analysis of agreement was carried out. METHODS: This was done by means of the 18-item Foot Function Index in its validated German translation by Naal et al. (FFI-D). The results of 91 orthopedic @entity1 as well as healthy @entity1 in both scores were then compared intraindividually. The cohort consisted of 46 individuals with @entity74 and 45 @entity1 without any hindfoot complaints. The FFI-D-Score was linearly transformed in the range 0-100 points of the AOFAS. RESULTS: Encouraging correlation was then found for the @entity1 with @entity74 (Spearman's correlation 0.73 (95% CI 0.52-0.85); a median deviation of -2 points (interquartile range -13 points; +13 points) in @entity1 with @entity74 implied good median intraindividual score concordance. However, with 30 of these 46 @entity1 showing score deviations beyond or below a pre-specified   10 points range of clinically tolerable deviations, the scores cannot be considered exchangeable. CONCLUSION: Although the agreement analysis was performed for the German translation of the two questionnaires, analogous results can be expected also for other languages. It should be noted that the results do not allow for judging which of the scores is better suited to give a valid statement on @entity1 outcome in treatment of @entity74 . To verify which of these two scores is better suited to represent hindfoot-dysfunction a subsequent study using instrumental gait analysis and surface EMG is being carried out.
