Table 4 Spearman correlation between the per cent changes in fractional anisotropy and clinical scores (n = 12).

Region of per cent reduction in FA	Per cent reduction in NIHSS rs (p)	Per cent reduction in FM scale rs (p)	Per cent reduction in BI rs (p)
Above the internal capsule	−0.47 (0.04)	−0.56 (0.02)	−0.39 (0.09)
Internal capsule	−0.41 (0.08)	−0.44 (0.06)	−0.11 (0.27)
Below the internal capsule	−0.51 (0.03)	−0.68 (0.01)	−0.22 (0.19)

BI, Barthel Index; FA, fractional anisotropy; FM scale, Fugl‐Meyer scale; NIHSS, National Institutes of Health Stroke Scale.

The per cent changes in FA value: ((W12FA value –W1FA value)/W1FA value × 100%). The per cent changes in clinical scores: ((W12scores – W1scores)/W1scores × 100%).
