tDCS in Post-COVID Syndrome: Comparison of Two Targets

January 28, 2024 updated by: Jordi A Matias-Guiu, Hospital San Carlos, Madrid

Neuromodulation Using Transcranial Direct Current Stimulation (tDCS) in Post-COVID Syndrome: Comparison of Two Targets

The main aim of this study is to compare the effect of two non-invasive neuromodulation targets in patients meeting WHO criteria for the post-COVID condition. A randomized, parallel, double-blind study will be conducted. Patients will receive 15 neuromodulation sessions through transcranial electrical stimulation for 3 weeks, associated with cognitive stimulation during therapy. The main objective will be to evaluate the change in physical fatigue. As secondary objectives, changes in cognition, depression, pain, quality of sleep and quality of life will be evaluated. The objective of this study is to evaluate the effect of two targets (left dorsolateral prefrontal and M1) of the neuromodulation intervention, together with cognitive stimulation.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Active, not recruiting

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Enrollment (Estimated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 65 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Confirmed diagnosis of COVID-19 at least 6 months before the participation in the study.
  • Diagnosis of post-COVID condition according to WHO criteria.
  • Age 18-65 years.
  • Spanish as native language.
  • Sign of written informed consent.

Exclusion Criteria:

  • History of stroke
  • History of traumatic brain injury or central nervous system infection
  • Diagnosis of other neurological or medical disorder that could impact on fatigue.
  • Diagnosis of active psychiatric disorder potentially impacting on fatigue or cognitive function.
  • Chemotherapy or radiotherapy for cancer.
  • Severe sensory deficits (e.g. visual loss) that could limit assessments included int the study protocol.
  • Taking drugs or uncontrolled medical disorder potentially causing or worsening fatigue. Specifically, uncontrolled adrenal insufficiency, miastenic syndromes, thyroid disorders, cardiac failure, chronic kidney disorders and neurodegenerative disorders are excluded.
  • History of abuse of alcohol or other toxics.
  • Any contraindication for transcranial electric stimulation: epilepsy, pregnancy, metallic implants, brain devices, pacemakers, head injuries).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
