Summary

Dizziness Handicap Inventory (DHI) scores indicate a significant handicap in most patients with dizziness, particularly in physical function. However, DHI did not correlate well with objective balance tests like Computerized Dynamic Posturography (CDP).

Area of Science:

  • Neuroscience
  • Audiology
  • Vestibular Science

Background:

  • Dizziness is a common complaint impacting quality of life.
  • Objective measures of balance function are crucial for understanding dizziness.
  • The Dizziness Handicap Inventory (DHI) and Computerized Dynamic Posturography (CDP) are tools used in neurotologic evaluations.

Purpose of the Study:

  • To assess the handicapping effect of dizziness using the Dizziness Handicap Inventory (DHI).
  • To evaluate objective balance function using Computerized Dynamic Posturography (CDP).
  • To determine correlations between subjective dizziness handicap and objective balance measures.

Main Methods:

  • 101 consecutive patients referred for neurotologic dizziness evaluation were assessed.

  • Dizziness Handicap Inventory (DHI) was used to measure subjective handicap.
  • Computerized Dynamic Posturography (CDP) was employed for objective balance assessment.

    • Main Results:

    • Most patients reported some pre-existing handicap, primarily in the DHI Physical subscale.
    • Females and patients with bilateral lesions generally scored higher on all DHI subscales.
    • No significant clinical correlations were found between DHI scores and CDP results, though higher DHI scores were noted in patients failing CDP conditions.

    Conclusions:

    • Subjective dizziness handicap, as measured by DHI, does not strongly correlate with objective balance deficits measured by CDP.
    • Functional balance ability could not be correlated with patient-reported handicap.
    • Anxiety and coping strategies may influence the discrepancy between dizziness symptoms and objective findings.
