Abstract

The Parkinson's disease (PD) patients' behavior during walking on uneven terrain is less known. Furthermore, we didn't find any paper that studied the visual control during obstacle avoidance task in PD patients. The aim of this study is to analyze the role of vision in the locomotor control during obstacle avoidance of different heights in PD patients and healthy elderly. It has been collected data of 14 PD patients (from 1 to 3 stages in the Hoehn & Yahr Scale) and 14 healthy elderly matched by age, gender and anthropometric characteristics. Participants were invited to walk on an 8m long pathway, under conditions without obstacle (WO), ankle height obstacle (AO) and mid shank height obstacle (MSO). After the researcher's command, at his/her preferred velocity, the participant should walk toward the obstacle, step over it and walk to the end of the pathway. The trials combined conditions of vision (DVI = dynamic visual information; SVI = static visual information; SSVI = self-selected visual information) and obstacle (WO, AO, MSO); twenty-seven trials were realized; they were distributed in 3 blocks. The visual sample was manipulated by the use of liquid crystal display goggles. Kinematics and kinetic analysis were realized by digital camcorders and two force plates (AccuGait, Advanced Mechanical Technologies, Boston, MA), respectively. The selected dependent variables refer to the spatial and temporal parameters during the approaching and crossing phases and variables extracted from normalized force-time curves. MatLab7.0 software will be used for filtering and calculating the dependent variables. Variables will be statistically treated in a descriptive way and by the multivariate analyses. (AU)
