BPVD indicates bilateral peripheral vestibular dysfunction; CVD, central vestibular dysfunction; DHI-G, Dizziness Handicap Inventory - German version; HADS, Hospital Anxiety Depression Scale; multisensory/multifactorial causes of dizziness; SD, standard deviation; UCLA-DQ, University of California Los Angeles - Dizziness Questionnaire; UPVD, unilateral peripheral vestibular dysfunction;

a Maximum score of the DHI-G: 100 points; higher scores mean more disability

b Maximum scores of the functional and emotional subscale: 36 points

c Maximum score of the physical subscale: 28 points

d Maximum score of the HADS: 42 points; higher scores mean more anxiety or depression

e Maximum scores of the anxiety and depression subscale: 21 points
