简要总结
The study will include subjects diagnosed with Dystonic Tremor (DT), Essential Tremor (ET), and healthy controls in the age range of 21-80 years. Electroencephalography (EEG) will be used as the primary outcome measure. Transcranial Magnetic Stimulation (TMS) will be used over the motor cortices or cerebellar cortices as an intervention that is expected to have short-term (less than an hour) electrophysiological effects.
详细描述
The primary goal of this study is to compare differences in cortical activity of patients with tremor before and after applying a session of rTMS. Specifically, the investigators will apply rTMS to the primary motor cortex (M1) as our group and others have shown abnormal function of the region. Moreover, a study shows that targeting of M1 and the dorsal premotor cortex (dPMC) with rTMS results in a trend towards improved clinical outcome in patients with focal hand dystonia and cervical dystonia. The central hypothesis of this study is that rTMS can modify cortical oscillations in patient populations with tremor and that the investigators will be able to detect these changes with the use of Electroencephalography (EEG). By applying inhibitory rTMS to the motor cortices, the investigators may expect a shift in cortical oscillations towards normal activity.

结局指标
主要结局
Cognitive Assessment Using MoCA Version 7.1 Scores
时间窗: Day 1
Montreal Cognitive Assessment Version 7.1 was used to assess cognitive ability. This scales is score from a range of 0 to 30 with a score of 24 or less indicating mild cognitive impairment. Moderate cognitive impairment is indicated by a score of 18-23 and severe impairment is a score of 10 or less. Overall, a higher number indicates better cognitive ability.
