Table 2. Motor Function Correlation with Diffusion Indices.

Spearman's rank correlation coefficients (ρ) between per-subject motor scores and fractional anisotropy or mean diffusivity values from ROI-analyses of right and left posterior limbs of the internal capsule (PLICs, p < 0.001) and corticospinal tracts (CSTs, p < 0.005) are reported.

Region of interest	Spearman's ρ
	Fractional anisotropy	Mean diffusivity
Right PLIC	0.807 (p < 0.001)	- 0.827 (p < 0.001)
Left PLIC	0.814 (p < 0.001)	- 0.827 (p < 0.001)
Right CST	0.845 (p < 0.005)	- 0.776 (p < 0.005)
Left CST	0.807 (p < 0.005)	- 0.777 (p < 0.005)
