Validation of the German Version of the New Freezing of Gait Questionnaire for People with Parkinson‘s Disease
Freezing of gait (FOG) in Parkinson’s disease (PD) is a highly disabling symptom which impacts quality of life. The New FOG Questionnaire (NFOG-Q) is the most commonly used tool worldwide to characterize FOG severity in PD. This study aims to provide a German translation of the NFOG-Q and to assess...

The German version of the NFOG-Q shows good internal consistency (Cα = 0.84).
