Response variability of different anodal transcranial direct current stimulation intensities across multiple sessions.

ABSTRACT:

Background

It is well known that transcranial direct current stimulation (tDCS) is capable of modulating corticomotor excitability. However, a source of growing concern has been the observed inter- and intra-individual variability of tDCS-responses. Recent studies have assessed whether individuals respond in a predictable manner across repeated sessions of anodal tDCS (atDCS). The findings of these investigations have been inconsistent, and their methods have some limitations (i.e. lack of sham condition or testing only one tDCS intensity).

Objective

To study inter- and intra-individual variability of atDCS effects at two different intensities on primary motor cortex (M1) excitability.

Methods

Twelve subjects participated in a crossover study testing 7-min atDCS over
