Correlation between beta-power and foot stomping speed (steps per second), across study session, excluding two non-responders (P01 and P09, N=8) to neurofeedback. Each participant contributed five data points: one during baseline foot stomping (FS), two during pre-neurofeedback FS, and two during post-neurofeedback FS. Both beta-power and movement speed were z-scored across all data points to allow comparison across participants and to report standardized effect sizes. The black regression line represents a linear fit across all trials, with a 95% confidence interval shown in gray.
