Abstract: Objective：The English version of the Characterizing Freezing of Gait questionnaire (C-FOGQ) that is used to assess detailed information of freezing of gait was developed by Ehgoetz Martens et al. This study aims to develop the Japanese version of the C-FOGQ using guidelines for cross-cultural adaptation and to conduct the pretesting study.Methods：The C-FOGQ was translated with permission into Japanese according to the following guidelines for cross-cultural adaptation： (1) translation (English to Japanese), (2) back-translation (Japanese to English), and (3) pretesting. Thirty-nine patients with parkinsonism-related disorders participated in the pretesting study.Results：There was no significant linguistic problem in the process of translation and back-translation. In pretesting, the average response time of the Japanese version of the C-FOGQ was 526.8 seconds. The error/no-response rate was less than 1%. The average score for section II of the Japanese version of the C-FOGQ was 20.0 points.Conclusion：A linguistically-validated Japanese version of the FOGQ was developed according to the guidelines of cross-cultural adaptation. It seems to be possible to use this questionnaire for detailed evaluation of gait freezing in Japan as well as in the West.
