MST for Parkinson's Disease

"MST treatment will be administered over the frontal/vertex cortex using 100 Hz stimulation using the MagPro XP MST with Cool TwinCoil. The MST determination of seizure threshold will be done using 100% machine output applied at 100 Hz at progressively escalating train durations, commencing at 2 seconds and increasing by 2 seconds with each subsequent stimulation until an adequate seizure is produced. During subsequent sessions, one stimulation will be delivered using a train duration that is 4 seconds longer than the train duration at threshold (with a maximum train duration of 10 seconds).~MST treatments will be administered twice a week, for up to 16 treatments. This will be performed under the effect of anesthesia. The treatment procedure is approximately 10 minutes, followed by a recovery period of approximately 30 minutes."
