Dizziness Handicap Inventory correlates of computerized dynamic posturography.

To assess the handicapping effect of dizziness related to posture and balance, the Dizziness Handicap Inventory (DHI) and Computerized Dynamic Posturography (CDP) were used to assess 101 consecutive patients referred for neurotologic evaluation of dizziness. Most patients, regardless of diagnosis, related some level of preexisting handicap, most often in the DHI Physical subscale. Generally, females and patients with bilateral lesions scored higher in all DHI subscales. No clinically useful correlations emerged between DHI and CDP testing, although DHI scores were marginally higher for patients failing CDP conditions. Functional balance ability could not be correlated with patient handicap, but a literature review suggests that the desynchrony between dizziness signs and symptoms may be related to underlying patient anxiety and differences in coping strategies.
