The top row shows box and whisker plots comparing the gait parameters estimates from the 2-min walk test for PD in white, PSP in gray. The box plots show the median (middle line), 25th and 75th percentiles, and the mean (X). The second row shows the Spearman correlations p between components of the TUG test and the modified PSPRS. C Shows the Spearman correlations p between components of the TUG test and the virtual UPDRS part III. * represents p value < 0.05, ** represents p value < 0.01, *** represents p value < 0.001
