Application of Direct Current Transcranial stImulation, Remotely superVised in Chronic fATiguE

It is a one-arm open-label interventional study with transcranial direct current stimulation in an remote home-based setting with the aims to evaluate the feasibility (usability of the device, compliance of patients, usability of the teletherapy), the effectiveness (clinical ratings) and the compatability of this intervention in 20 patients with myalgic encephalomyelitis/chronic fatigue syndrome.
