Transcranial Direct Current Stimulation of the Motor Cortex in Essential Tremor

The current research is aimed at using Transcranial Direct Current Stimulation (tDCS) as complementary therapeutic tool in the treatment of essential tremor. Patients will be randomized into two groups (tDCS-cathode vs. tDCS-sham) according to detailed protocol. Main outcome will be measured by the change in tremor amplitude using an accelerometer pre and post cathodal tDCS of the motor cortex. A total of 40 patients ought to be enrolled as specified in methodology. Secondary outcomes will assess TRG essential tremor rating assessment scale (TETRAS) as well as clinical monitoring.
