The purpose of this study is to evaluate the efficacy and electrophysiology of repetitive transcranial magnetic stimulation in the treatment of essential tremor.
This is a randomized controlled study.The purpose is to evaluate the efficacy of repetitive transcranial magnetic stimulation(rTMS) in the treatment of essential tremor,and explore the possible mechanism by detecting the changes of clinical scale and TMS-electroencephalogram(TMS-EEG), so as to seek an effective therapy for essential tremor.

| The efficacy of the treatment on the essential tremor evaluated by Essential Tremor Rating Assessment Scale (TETRAS) score | The TETRAS is widely used tremor evaluation scale.TETRAS has been used for evaluation tremor in patients with essential tremor focuses primarily on the assessment of activities of daily living and tremor.The TETRAS score ranges from 0 to 112. The higher the TETRAS score, the more severe the symptoms. | visit 1(baseline), visit 2(Day 10), visit 3(Day 30) |
