Patients with focal arm dystonia have increased sensitivity to slow-frequency repetitive TMS of the dorsal premotor cortex.


We used PET to examine the pattern and time course of changes produced by repetitive transcranial magnetic stimulation (rTMS) over the dorsal premotor cortex (PMd) in healthy subjects and in patients with primary focal dystonia. Subjects received 1800 stimuli of subthreshold 1 Hz rTMS or sham stimulation to the left PMd. Afterwards, we measured regional… (More)
