EEG as Predictor of HD-tDCS Effectiveness in Long COVID-19

Status Recruiting

Clinical Trial Summary

COVID-19 is an infectious disease which presents a heterogenous clinical presentation. Recent investigations suggest that people who were infected by COVID-19 often develop physical disabilities (i.e. pain, fatigue) and neurological complications after hospital discharge. Many therapeutic approaches such as transcranial direct current stimulation (tDCS) have been proposed to minimize functional and structural impairments. Electroencephalogram (EEG) has been used in this population to assess electrophysiological changes in the brain. However, evidences about EEG utilization as efficacy predictor of tDCS in COVID-19 people rest inconclusive.Our objective is to evaluate EEG as neurobiological predictor marker of tDCS efficacy on fatigue, pain, quality of life, self-efficacy and functional capacity in the chronic phase of COVID-19.

Clinical Trial Description

A double-blinded randomized clinical trial will be carried to analyse the EEG as neurobiological predictor marker of HD-tDCS 4x1 in patients in long COVID-19. This study is in accordance with the CONSORT guidelines, which will investigate the effectiveness of treatment with HD-tDCS. Patients who had a medical diagnosis of COVID-19, clinically stable, able to respond to simple commands, able to walk for six minutes and who sign study consent form will be enrolled. Those who present associated neurological diseases, pregnant, users of psychoactive drugs, patients who have metallic implants, electronic devices, pacemakers, or epileptic patients will be excluded. Patients will be allocated randomly to the experimental group or sham control. Sessions for experimental group consist of anodal HD-tDCS on Left diaphragmatic primary motor cortex associated to respiratory training (10 sessions, 3mA, 20 minutes/session). In the sham condition, the device provided a 30-second ramp-up period to the full 3 mA, followed immediately by a 30-second ramp down. Patients will be assessed in three moments: pre-treatment, post-treatment and after 30 days treatment ending (follow-up). ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
