title: Is there a relationship between objective and subjective assessment of balance in elderly patients with instability?
abstract: To assess whether a subjective questionnaire that measures the disability caused by balance disorders in daily life activities is correlated to objective assessment of balance in elderly patients with age-related instability. We included 37 subjects aged 65 years or more who presented balance disorders induced solely by age. Balance assessment was through the sensory organisation test and limits of stability of computerised dynamic posturography, the SwayStar system and the modified timed up and go test. The patients also completed the dizziness handicap inventory (DHI) questionnaire. The SwayStar balance control index (BCI) was most significantly correlated to the DHI score and the score of its different scales. When we divided the patients into subgroups according to DHI score, we only found statistically significant differences in the BCI and number of falls. In our population of elderly patients with instability, there is practically no correlation between the DHI and the static balance assessment. However, there is greater correlation with the BCI, which could show that dynamic balance is perceived as more disabling for these patients. In this case, when designing a rehabilitation protocol we should focus more on dynamic activities such as gait.
