A) xy-plot of the displacement of the CoP in both the anterio-posterior (A/P) and in the medio-lateral (M/L) direction that illustrates the changes in the center of pressure during light and heavy touch in comparison to the no touch condition in a representative subject with Parkinson’s disease without medication (OFF). B) The mean and SD of the root mean square (RMS) of the center of pressure (CoP) in A/P and C) M/L direction as well as the CoP velocity in D) A/P and E) M/L direction during no touch (NT), heavy touch (HT) and light touch (LT) in age-matched control subjects as well as in subjects with Parkinson’s disease (PD) OFF and ON their medication.
