Vestibular neuritis 28 (32) 3.50 (5.07) 0.15 (0.30) 0.33 (0.44)
Non-otogenic dizziness 18 (14) 5.83 (7.63) 0.21 (0.51) 0.59 (0.73)
Cervical dizziness 16 (26) 6.75 (5.95) 0.29 (0.33) 0.63 (0.55)
Total not dizzy sub-group 129 (26) 5.00 (7.28) 0.23 (0.48) 0.46 (0.59)
  1. Number of participants and distribution according to diagnostic category and scores on the Vertigo Symptom Scale Short Form (VSS-SF), the vertigo/balance (VSS-Va) and the autonomic/anxiety (VSS-Ab) sub-scales according to dizziness and diagnostic groupc in N = 494 patients examined in the period 1992–2001 in Bergen, Norway
  2. a VSS-V sum score divided by number of scale items (8)
  3. b VSS-A sum score divided by number of scale items (7)
  4. c Analyses of variance showed significant differences between dizzy and not dizzy patients for all scales (VSS-SF, VSS-V, VSS-A). The difference was significantly larger for VSS-V than for VSS-A. Diagnostic group had no significant effect on any of the scales
  5. SD: Standard deviation
