Abstract
Motor threshold is a means of quantifying stimulus in transcranial mag netic stimulation. Two methods are used. One involves neurophysiology techniques and the other is visualization of movement. The aim was to compare the percentage of total machine output (PTMO) necessary to ach ieve motor threshold using these different methods. Neurophysiological and visualization of movement thresholds were determined in six subje cts. in all subjects, the two thresholds were achieved with a <10% dif ference in PTMO. Determination of motor threshold with a neurophysiolo gical and a visualization of movement method produced similar results.
