The Effect of High-Frequency Repetitive Transcranial Magnetic Stimulation on Advancing Parkinson's Disease With Dysphagia: Double Blind Randomized Clinical Trial.

We investigate if rTMS has a therapeutic role in the treatment of dysphagia in patients with Parkinson's disease (PD). . Thirty-three patients with PD and dysphagia were randomly classified with ratio 1:2 to receive sham or real rTMS (2000 pulses; 20 Hz; 90% resting motor threshold; 10 trains of 10 seconds with 25 seconds between each train) over the hand area of each motor cortex (5 minutes between hemispheres) for 10 days (5 days per week) followed by 5 booster sessions every month for 3 months.
