Fig. 1: Relationship of right Supplementary Motor Area (SMA) anisotropy with step count and step length (SL).
From: Supplementary motor area microstructure defines the extent of gait impairment in Parkinson’s disease
Fractional anisotropy (FA) values are plotted against step count and step length (SL) for the right (SL R) and left (SL L) leg under three conditions: A normal gait, B fast gait, and C dual-task. Dot-coloring: MDS UPDRS III FoG score ≥1: red, FoG score of 0: blue. Lower FA values, are associated with fewer and longer steps. Raw data points are presented along the model fit. PFDR - P-value corrected for False-Discovery-Rate (FDR), R² - the partial R² value for FA from the model - the amount of unexplained variance reduced by the FA value is appended as a percentage.
