Cross-sectional comparison of digitomotography measures between early patients with PD, mid-stage PD and controls.

Data are presented with mean (standard deviation). Statistical comparisons were performed with ANOVA (right column). Results of analyses between single cohorts (controls versus early Parkinson’s disease (PD), controls versus mid-stage PD, early PD versus mid-stage PD) are displayed as follows: Compared to controls without ° and with °° Bonferroni correction (p ** Compared to early PD with Bonferroni correction.CoV, coefficient of variation; DEV mean, mean tap deviation from the predefined 1.55 Hertz cueing tone; DEV SD, variability of tap deviation from the predefined 1.55 Hertz cueing tone; IPI, interpeak interval; SD, standard deviation; TF, tap force.Cross-sectional comparison of digitomotography measures between early patients with PD, mid-stage PD and controls.
