Computerized dynamic posturography (CDP) assesses balance by integrating sensory inputs. It provides functional insights into balance deficits and predicts physical therapy benefits for patients with vestibular disorders.

Area of Science:

  • Neuroscience
  • Biomechanics
  • Otolaryngology

Background:

  • Posturography has evolved with computerized dynamic posturography (CDP).
  • CDP integrates force platforms with visual stimuli to evaluate sensory input for balance.
  • It assesses overall balance rather than directly measuring peripheral or central vestibular function.

Purpose of the Study:

  • To review the current status of computerized dynamic posturography.
  • To highlight its utility in assessing patients with suspected vestibular disorders.
  • To discuss the interpretation of CDP patterns and their clinical significance.

Main Methods:

  • Utilizes the Equitest device by NeuroCom International.
  • Employs the sensory organization test (SOT) to assess balance.

  • Analyzes patient responses to varying sensory conditions.

    • Main Results:

    • Specific CDP patterns, like 'vestibular pattern' and 'surface dependence', are observed in patients with vestibulospinal deficits.
    • CDP can track compensation for peripheral vestibular loss over 2-3 weeks.
    • Discrepancies with other vestibular tests (e.g., electronystagmography) suggest CDP measures a different aspect of vestibular function.

    Conclusions:

    • CDP offers valuable functional information on balance and its impact on daily living.
    • It does not provide localization or etiological data but assesses balance control.
    • CDP can predict patient response to physical therapy interventions for balance disturbances.
