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) |
|---|---|---|---|
| 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%). | |||
