Essential Tremor | Experimental Therapeutics in Essential Tremor Using Cerebellar Transcranial Direct Current Stimulation

Essential Tremor research study

What is the primary objective of this study?

The purpose of this study is to determine whether transcranial cathodal direct current stimulation (tDCS) delivered over the cerebellum can improve essential tremor.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
