  1. 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;
  2. a Maximum score of the DHI-G: 100 points; higher scores mean more disability
  3. b Maximum scores of the functional and emotional subscale: 36 points
  4. c Maximum score of the physical subscale: 28 points
  5. d Maximum score of the HADS: 42 points; higher scores mean more anxiety or depression
  6. e Maximum scores of the anxiety and depression subscale: 21 points
