Abstract

Age-related disabilities affect the body balance in humans and negatively impact health and the quality of life. The control of posture in humans is not fully comprehended yet and it has under intense scientific investigation.Hence, the purposes of the present study are 1) The implementation of a public database of postural sway signals in young and elderly adults; and 2) Investigation of the mechanisms of postural control by modeling and simulation studies.The implementation and deployment of this public data base containing human postural control signals will allow the access of a normative data set from research groups worldwide. The use, testing and, possibly, validation of innovative data analysis techniques for postural control data, can eventually be performed in the same data set. By doing this, a more objective assessment and comparisons of these different data analysis methods can be undertaken. This project aims to improve the current data analysis methods used to detect changes in postural control and the development of innovative ones. In addition, the development of computational models and simulation will allow clarifying specific research questions about the mechanisms of postural control that have been widely debated in the scientific community. In particular, the collected data during the first stage of the present study would be better interpreted with this modeling and computational simulation stage. (AU)
