|---|---|---|---|---|---|
| Comparison (Data 1 vs. Data 2) | Similarity Index | Data 1 | Data 2 | Data 1 | Data 2 |
| 40% MLF vs. 15% MLF in controls (n = 6) | 0.893 ± 0.135 | 93.8 ± 2.4 | 94.8 ± 2.5 | 92.3 ± 9.1 | 94.0 ± 5.0 |
| All trials in stroke vs. trials with arm rotation matched to controls (n = 7) | 1.0* | 89.9* | 88.8* | 89.3 ± 6.1 | 87.0 ± 8.0 |
| Dominant vs. nondominant arms in controls (n = 6) | 0.853 ± 0.162 | 94.4 ± 2.0 | 94.4 ± 1.6 | 93.1 ± 7.6 | 93.6 ± 4.9 |
VAF, variance accounted for; MLF, maximum lateral force.

Comparison performed with data pooled across subjects in two groups, so no means ± SD value available for similarity index and global VAF. Due to technical issues, rotational data were only available for 7 stroke survivors.
