P225 Effect of 30, 50 and 100Hz tetha burst stimulation on healthy individuals

Continuous tetha burst stimulation (cTBS) protocol mainly consists of 3 stimulus bursts repeating every 200ms at 50Hz and It has been interpreted that cTBS had inhibitory effects on human motor cortex. On the other hand, there are some reports that 50Hz cTBS had variability within and between subjects on cortical excitability. In addition, little was known about the effect of different cTBS modalities. The objective of this study is to investigate the effects of 50Hz, 30Hz and 100Hz cTBS on motor cortical excitability healthy subjects.
