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 high definition (HD-tDCS) have been proposed to minimize functional and structural impairments. Recently, I electroencephalogram (EEG) has been used as predictor of HD-tDCS effectiveness in diverse neurological populations. However, evidences about this tool utilization as efficacy predictor of tDCS in COVID-19 people rest inconclusive. Thereby, our objective is to evaluate HD-tDCS efficacy on fatigue, pain and functional capacity of patients with COVID-19 chronic.
We propose a sham-controlled randomized clinical trial with patients in COVID-19 chronic. They will be evaluated according to following eligibility criteria :
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).

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Experimental Group/ Active HD-tDCS | Experimental | Patients who will be randomly enrolled in this group. They will receive 10 sessions of anodal stimulation on cortical representation zone of left diaphragmatic motor cortex using HD-tDCS associated to respiratory training; for 20 minutes (each session) with a 3mA intensity. The electrical current will be delivered with a ramp-up time of 30 s, held at 3mA for 20 min, and then ramped down over 30 s. |
|
| Control Group / Sham Group | Sham Comparator | Patients enrolled in this group condition will receive 10 sessions of anodal stimulation on cortical representation zone of left diaphragmatic motor cortex using HD-tDCS associated to respiratory training; for 20 minutes (each session) with a 3mA intensity. In the sham condition, the device will provide a 30-second ramp-up followed immediately by a 30-second ramp down. |
