Time differentiated normalized motor evoked potential amplitudes (nMEP). A) Mean of recorded nMEP amplitudes for each time point across all 30 sessions for active and sham iTBS are presented for participants with SCI. Error bars represent one standard deviation from the mean. B) In the SCI group, the linear mixed effects model (LMEM) shows a significant difference over time in nMEP amplitudes depending on the type of iTBS, active or sham. C) In the nonimpaired group, the LMEM does not show an effect of stimulation type on nMEP amplitude. D) There was a difference in the effect of iTBS between groups, based on the LMEM, consistent with the excitation seen in the SCI group and not seen in the nonimpaired group. Each point represents all nMEPs across all sessions, for the given group and stimulation type
