Note: The table shows the average stimulation intensity to elicit a MEP of >0.1 mA in five out of ten trials at the anterior tibialis muscle during rest (= resting motor threshold, RMT) and during slight activation of the muscle (= active motor threshold, AMT) at each visit. The data (mean ± standard deviation) are provided as percentage of the maximum output of the stimulator. Abbreviations: AMT—active motor threshold; iTBS—intermittent theta-burst stimulation; MEP—motor evoked potentials; RMT—resting motor threshold.
