Correlation between gait speed, gait smoothness and executive functions. Single, Cognitive, Motor: single task modality, cognitive and motor dual-task; AP: anterior-posterior; RMS: root mean square; SPARC: spectral arc length measure (dimensionless, 1); FAB: Frontal Assessment Battery. The FAB scores are split into < and ≥ the median (vertical dashed line). Rho: Spearman’s rho; p: p-value of the Spearman correlation. The boxplots show the speed and SPARC values in the participants’ sample split according to the median FAB value to make the association between walking metrics and executive functions more apparent
