Figure 5. Changes in motor cortical excitability in the RIGHT hemisphere for each stimulation condition (anodal, dual and sham).

Both active stimulation conditions were associated with an excitability-enhancing effect at both time points in the right hemisphere, but this was significantly larger in the dual condition.

**=p<0.01, *=p<0.05; Error bars are 95% confidence intervals (CI) calculated on the transformed data and transformed back to the original scale.
