Is this trial a fit for you?

Likely a good fit

Adults (16 years and older) with confirmed past COVID-19 infection and persistent symptoms such as migraines, headaches, chronic pain, neuropathic pain, arthralgia, myalgias, or sleep problems.

Probably not a fit

Individuals without persistent COVID symptoms or those with contraindications to tDCS or implanted cranial devices may not experience benefit.

What this trial studies

This interventional study investigates the effects of transcranial direct current stimulation (tDCS) in patients with persistent COVID-19 symptoms, focusing on headaches, migraines, chronic pain, and sleep problems. The trial includes an initial open-label phase followed by a randomized, sham-controlled, double-blind extension with four arms: anodal, bifrontal, cathodal, and sham tDCS. Enrollment aims for 27 participants in the initial phase and 60 in the extension phase, with primary outcomes unchanged and sleep measures added as secondary outcomes. Participants are adults with a confirmed past COVID-19 infection and persistent symptoms, and key exclusions include implanted devices or pregnancy. The study is conducted at the Catholic University of Valencia and affiliated sites in Valencia, Spain, under ethics approvals from the same institution.

Why it matters

Potential benefit: If successful, participants may experience reduced headaches, pain, and sleep disturbances due to tDCS treatment.

How similar studies have gone: Previous use of tDCS in migraine, chronic pain, and sleep disorders suggests potential benefits, but application to long COVID is relatively novel.
