rTMS for the Treatment of Freezing of Gait in Parkinson's Disease

It is delivered at a 5-second burst of 10Hz stimuli, repeated 20 times at every minute. Each treatment contains a total of 1000 pulses. Stimulus intensity is 90% of resting motor threshold. The SMA stimulation will be given using a coil centered at points 3-cm anterior to the leg motor area in the sagittal midline.

The procedure will be same as the high-frequency rTMS except that the coil is 90° angled away.
