Fig 4. Correlations with clinical outcomes.

Fig 4

Scatter plots showing the relationships between neurophysiological and clinical outcomes. a-c) relation of comfortable walking speed with index of corticospinal excitability (ICE; black circles, left vertical axis) and ipsilateral silent period (iSP; gray squares, right vertical axis) in the paretic limb. More positive ICE values reflect greater contralateral motor excitability. Subfigure a, b, and c represent ICE values from the dynamic bilateral, dynamic unilateral, and isometric unilateral conditions, respectively. d) relation of paretic ankle track accuracy with contralateral silent period (cSP; black circles, left vertical axis) and ipsilateral silent period (iSP; gray squares, right vertical axis) in the paretic limb. e) relation of index of corticospinal excitability (ICE) in the non-paretic limb and with stance symmetry ratio (black circles, left vertical axis) and swing symmetry ratio (gray squares, right vertical axis). More positive ICE values reflect greater contralateral motor excitability. A symmetry value of 1 reflects perfect symmetry between the paretic and non-paretic limb.
