title: Analysis and reliability of posturographic parameters in Parkinson patients at an early stage.
abstract: Aim of this work was to evaluate Parkinsonian (PARK) patients at their initial stage of the disease by static posturography in order to study: the stability of posture system; the role of visual input; the influence of an acute administration of levodopa. This would allow the creation of a database that can be useful to follow the progression of the disease. Attention was also focused on the assessment of the reliability of quantitative posturographic parameters (PP); a large number of PP that can be derived using classical, structural, and nonlinear approaches have been considered. Particular attention has been given to this latter approach. The class of PD subjects examined in this work resulted to be very different from classical Parkinsonian subjects studied in literature.
