Table 5.
The post-hoc t-tests with a Bonferroni corrected alpha level for comparisons across time (p<0.0025) for the normalized electromyographic mean power frequency (EMG MPF) responses including the mean difference between time points, 95% confidence interval of the difference, effect size (Cohen’s d), and p-value between each time point.
