Posturography techniques to identify balance problems in elderly individuals with vestibulopathy - a comparison study

Area of Science:

• Vestibular System Disorders
• Geriatric Medicine
• Biomechanics

Background:

• Vestibular disorders significantly impact balance and mobility, especially in the elderly.
• Accurate assessment of postural control is crucial for managing individuals with vestibular dysfunction.
• Different posturography methods may offer varying sensitivity in detecting balance impairments.

Purpose of the Study:

• To compare the efficacy of computerized dynamic posturography (CDP) and mobile posturography (MP) in assessing postural outcomes.
• To evaluate the performance of these methods across four distinct postural conditions.
• To identify age-related differences in postural control using these assessment tools.

Main Methods:

• Participants with vestibular disorders were stratified into two age groups: 18-60 years and over 60 years.
• Both groups underwent assessment using CDP (EquiTest System®) and MP (Vertiguard System®).
• Testing encompassed four conditions: eyes open/closed on stable/unstable surfaces.

Main Results:

• The elderly group exhibited poorer overall outcomes with CDP compared to the younger group.
• No significant differences in outcomes were observed between age groups when using MP.
• CDP identified more abnormalities in the elderly, particularly in condition 4 (eyes open, unstable surface) during MP assessment.

Conclusions:

• CDP demonstrates higher sensitivity in detecting abnormal postural sway in elderly individuals with vestibular disorders.
• Mobile posturography, specifically condition 4, appears sensitive for identifying postural instability in this population.
