Abstract

The objectives of this study were to evaluate a novel design dynamic force platform the Quantitative Posturography System (QPS). The evaluation consisted of identifying the effects due to ageing and disease of the postural control system and also to examine the relationship between functional performance and postural sway. An AOVA design and Pearson-Product correlation design were used. Seventy healthy subjects, seven subjects with Parkinson’s disease and eight subjects with a history of falls took part in the study. It was found that the QPS was able to identify changes due to both the ageing process and disease on the postural control system. Also a moderate correlation coefficient was found between the sway parameters of the QPS and the two functional balance assessment tests, the Single Leg Stance Test (SLST) and the Functional Reach Test (FR test). In conclusion, the QPS was able to detect the change in the postural control system due to both the ageing process and disease. It was also found that there is a moderately strong relationship between functional performance and postural sway.
