Static posturographic recordings were obtained from six Parkinson’s patients and six age-matched, healthy control participants. The availability of vision and visuo-spatial cognitive load were manipulated. Postural sway patterns were analyzed using recurrence quantification analysis (RQA), which revealed differences in center of pressure (COP) dynamics between Parkinson’s and control participants. AP COP trajectories for the Parkinson’s group were not only significantly more variable than for… CONTINUE READING
