Abstract

Postural ability can be evaluated through the analysis of body oscillations, by estimating the displacements of selected sets of body segments. The analysis of human movement is generally achieved through the exploitation of stereophotogrammetric systems that rely on the use of markers. Marker systems show a high cost and patient settings which can be uncomfortable. On the other hand, the use of force platform has some disadvantages: the acquisition of dynamics data permits to estimate only the body oscillations as a whole, without any information about individual body segment movements. Some of these drawbacks can be overcome by the use of video systems, applying a marker-free sub-pixel algorithm. In this paper, a novel method to evaluate balance strategies that utilises commercial available systems and applies methods for feature extraction and image processing algorithms is presented.
