Dual-Site Transcranial Magnetic Stimulation of the Supplementary Motor Area and Cerebellum for the Treatment of Essential Tremor.

Essential tremor is a common movement disorder that causes involuntary shaking, mainly during voluntary actions such as writing or holding objects. Recent research suggests that essential tremor is not caused by a single brain area, but by abnormal activity within a network that includes the cerebellum and motor areas of the brain. However, most non-invasive brain stimulation studies to date have targeted only one brain region and have shown inconsistent clinical benefits. This randomized, double-blind, placebo-controlled clinical trial aims to evaluate the effects of a dual-site transcranial magnetic stimulation (rTMS) protocol targeting the supplementary motor area (SMA) and the cerebellum in patients with essential tremor that does not respond adequately to standard medications. The study is based on previous pilot data showing meaningful tremor reduction using combined stimulation of these two brain regions. Participants will receive five sessions of rTMS, consisting of low-frequency stimulation over the SMA followed by high-frequency stimulation over the cerebellum. The main hypothesis is that this combined approach will lead to an immediate and sustained improvement in action tremor of the dominant upper limb, measured up to four weeks after treatment. Secondary outcomes include quality of life, safety, side effects, and changes in brain excitability associated with tremor improvement.
