Fig 2. Movements in participants with PD diverge from healthy movements proportional to disease severity.

A–Projection of healthy movement templates in healthy volunteers HV (gray) and PD (orange) participants. B–Projection of age matched healthy movement templates in gray and PD participants color coded according to the UPDRS score. C- Results of a linear regression model applied to the 3D of the RDS projections against the UPDRS score for each sensor aligned either with left or right step. The same analysis was repeated both for acceleration (left) and velocity (right). Only values with a p < 0.05 after correction for multiple comparisons (24: 6 sensors x 2 triggers x 2 conditions—velocity and speed) with Bonferroni method are shown.
