Association of motor impairment scores with the mean individual and cumulative lesion volumes for each region
| Lesion Type: | Lesion Volume,a cm3 | Correlation Between Impairment Score and Lesion Volume (p-value)b |
|---|---|---|
| Region 1 c | 15.9 (30.7) 0.09 - 126.2 |
-0.35 (0.025)* |
| Region 2 d | 4.1 (6.6) 0.0 - 28.5 |
-0.28 (0.10) |
| Region 3 e | 0.058 (0.051) 0.0 - 0.17 |
0.029 (0.86) |
| Region 4 f | 0.63 (1.1) 0.0 - 3.9 |
0.005 (0.98) |
| Region 1 + 2 | 19.6 (36.7) 0.12 - 154.7 |
-0.35 (0.028)* |
| Region 1 + 2 + 3 | 19.6 (36.2) 0.12 - 154.7 |
-0.34 (0.030)* |
| Region 1 + 2 + 3 + 4 | 19.9 (36.6) 0.20 - 154.7 |
-0.34 (0.032)* |
Data for entire patient sample (n = 41) is shown
a Lesion volumes are shown as mean (SD) and range
b Correlation between mean lesion volume of a Region and Fugl-Meyer motor impairment scores (Values are Spearman rank correlation coefficients, with p-values in brackets)
c Region 1 represents the lesion core
d Region 2 represents the peri-necrotic tissue
e Region 3 represents lesions in the same hemisphere as index stroke
f Region 4 represents lesions in the opposite hemisphere
