Transcranial direct current stimulation (tDCS) is an established technique to modulate cortical excitability^1,2. It has been used as an investigative tool in neuroscience due to its effects on cortical plasticity, easy operation, and safe profile. One area that tDCS has been showing encouraging results is pain alleviation ^3-5.

High-definition transcranial direct current stimulation (HD-tDCS), with its 4x1-ring montage, is a noninvasive brain stimulation technique that combines both the neuromodulatory effects of conventional tDCS with increased focality. This article provides a systematic demonstration of the use of 4x1 HD-tDCS, and the considerations needed for safe and effective stimulation.

A Protocol for the Use of Remotely-Supervised Transcranial Direct Current Stimulation (tDCS) in Multiple Sclerosis (MS)

Margaret Kasschau^1,2, Kathleen Sherman^1,2, Lamia Haider², Ariana Frontario^1,2, Michael Shaw^1,2, Abhishek Datta³, Marom Bikson⁴, Leigh Charvet^1,2

¹Multiple Sclerosis Comprehensive Care Center, Department of Neurology, NYU Langone Medical Center, ²Department of Neurology, Stony Brook Medicine, ³Soterix Medical, Inc, ⁴Department of Biomedical Engineering, The City College of New York

The goal of this pilot study is to describe a protocol for the remotely-supervised delivery of transcranial direct current stimulation (tDCS) so that the procedure maintains standards of in-clinic practice, including safety, reproducibility, and tolerability. The feasibility of this protocol was tested in participants with multiple sclerosis (MS).
