a Comparison of alpha EEG power before and after PoNS®, displaying statistically significant main effect of time; (b) Order by time interaction effect on alpha and theta power and Tukey pairwise post-hoc test statistical tests demonstrating a statistically significant increase alpha and theta power when exposed to HF stimulation in the first session; (c) Time-frequency spectral power for each exposure group (HF First and LF First) during each testing session
