The objectives of this study were to evaluate a novel design dynamic force platform, the quantitative posturography system. The evaluation consisted of identifying the effects due to ageing and disease on the postural control system and also to examine the relationship between functional performance and postural sway. Seventy healthy subjects, eight patients with Parkinson's disease and nine people with a history of falls took part in the study. It was found that the quantitative posturography system was able to identify changes in the postural control system due to both the ageing process and disease. Also a moderate correlation coefficient was found between the sway parameters measured by the quantitative posturography system and the two functional balance assessment tests, the single leg stance test and the functional reach test. A relationship was also found between functional performance and postural sway.
