History of Changes

Purpose

The purpose of this study is to determine whether transcranial direct current stimulation (tDCS) delivered over the motor cortex or the cerebellum can improve essential tremor and to identify the cerebral mechanisms involved in these potential effects.

Primary Outcome Measures:

Change from baseline in tremor amplitude on accelerometric recording 10 minutes after the end of tDCS [ Time Frame: 10 minutes after the end of tDCS ]

Secondary Outcome Measures:

Change from baseline in tremor amplitude on electromyographic recordings [ Time Frame: During tDCS (expected average of 15 minutes), 10 and 60 mn after the end of tDCS ]
Change from baseline in tremor amplitude on digitized tablet [ Time Frame: During tDCS (expected average of 15 minutes), 10 and 60 mn after the end of tDCS ]
Change from baseline in tremor amplitude on accelerometric recording [ Time Frame: During tDCS (expected average of 15 minutes) and 60 minutes after the end of tDCS ]
