Hindi Translation and Validation of the "Freezing of Gait Questionnaire" in Patient's with Parkinson's Disease

Background and aim:
Freezing of Gait-Questionnaire (FOG-Q) is the only valid and reliable subjective assessment tool for assessing freezing of gait severity. So, a Hindi version is required for usage in the Hindi-speaking population. The aim of this study was to cross-culturally adapt and validate the Hindi version of the Freezing of Gait-Questionnaire (HFOG-Q).
Methods:
The translation was done according to Beaton guidelines. 26 Hindi-speaking individuals with Parkinson’s disease were assessed using the HFOG-Q, Movement Disorder Society-Unified Parkinson’s Disease Rating Scale (MDS-UPDRS) I, II, and III, Fall efficacy scale (FES) & Hoehn and Yahr Staging.
Results:
HFOG-Q score was moderate to well associated with H&Y stage, MDS UPDRS item 2.13 (Freezing), item 3.10 (Gait), item 3.11 (Freezing of Gait), FES Score, MDS UPDRS I, MDS UPDRS II (rS = 0.516-0.688). There is a highly strong relationship between HFOG-Q and MDS UPDRS part III (rs = 0.761). A significant fair correlation between the HFOG-Q with PD duration and item 2.12 of MDS UPDRS (rS = 0.387-0.465) were found.
Conclusion: HFOG-Q is a valid tool for assessing FOG in Hindi-speaking populations.
Clinical implication: For usage in the Hindi-speaking individuals with Parkinson’s disease.
