Abstract
Aims: To explore changes in different outcome measures in a follow-up of persons with dizziness, and to investigate if these
changes indicate different domains of functioning. Methodology: Sixty-eight persons with dizziness, mean age of 47 years,
were included in an 18-month follow-up. Outcome measures used: the Vertigo Symptom Scale, Patient Specifi c Functional
Scale, Disability Scale, Dizziness Handicap Inventory, and tests of Dynamic Visual Acuity, Single Leg Stance, and Walking
Speeds. Major fi ndings: We found signifi cant improvements in impairments indicated by outcome measures of dizziness and
visual acuity, and in activity and participation indicated by outcome measures of standing balance, patient-specifi c activities,
disability and quality of life. Similar patterns of change were also found in subgroup analyses, except in gender. Correlations
between change-scores were in the range r 0 – 0.6. Signifi cant correlations were found between change scores indicating
body function and activity/participation (0.3 r 5). We found no correlations between self-report measures and tests.
Conclusion: Comprehensive use of outcome measures addressing body function, activity and participation appear to provide
information of changes in different domains of functioning. To enable broad and meaningful follow-up of patients with
long-lasting dizziness, generic and condition-specifi c measures, self-reports and tests in different domains of functioning
should be further explored.
