Power analysis: power was determined by simulation. Lower and upper lines define exactly the 95% CI for power, calculated based on the binomial distribution. N is the total sample size. The analysis was performed at a 0.05 significance level considering 2 × 2 factorial analysis of variance (ANOVA) (tDCS plus CIMT and sham tDCS plus CIMT from pretest to post-test). Power has been estimated here for an interaction term (A *C).
