Neuromodulation in COVID-19 Patients
Study Details
Study Description
Brief Summary
This clinical study is aimed at investigating the effects of transcranial direct current stimulation (tDCS) on COVID-19 patients not admitted to the intensive care unit. The tDCS is a non-invasive brain stimulation technique which applies a low intensity electrical current in order to modulate neuronal activity. Patients included will be submitted to a single session with active or sham tDCS, aiming to modulate prefrontal or supplementary motor area (SMA). Evaluation protocol will be performed before and after stimulation to verify the incidence of adverse events related to treatment and whether tDCS would affect measures of executive functioning, mood, anxiety, autonomic response and motor function in COVID-19 patients. We hypothesize the neuromodulation would be a safety, promising treatment to reduce possible impairments in COVID-19 patients.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: tDCS-SMA Participants randomized to this arm will receive a single tDCS session delivered at 2mA to the supplementary motor area (SMA) for 30 minutes. |
Device: Transcranial direct-current stimulation
A single tDCS session will be delivered to the supplementary motor area (SMA) by a DC stimulator (NeuroConn, Germany). During stimulation, a pair of saline-soaked sponge electrodes (surface 35 cm²) will be used, with one electrode (anode) placed 1,8 cm forward Cz and the other electrode (cathode) over the right supraorbital region, according to the International 10-20 EEG system. Current intensity will be ramp up for 30 seconds until reaches 2 mA, and after 30 minutes current intensity will be ramp down for 30 seconds.

| Experimental: tDCS- DLPFC Participants randomized to this arm will receive a single tDCS session delivered at 2mA to the right (cathodal) and left (anodal) dorsolateral prefrontal cortex (DLPFC) for 30 minutes. |
Device: Transcranial direct-current stimulation
A single tDCS session will be applied bilaterally over the dorsolateral prefrontal cortex (DLPFC) by a DC stimulator (NeuroConn, Germany). During stimulation, a pair of saline-soaked sponge electrodes (surface 35 cm²) will be placed over F3 (anode) and F4 (cathode), according to the International 10-20 EEG system. Current intensity will be ramp up for 30 seconds until reaches 2 mA, and after 30 minutes current intensity will be ramp down for 30 seconds.

| Sham Comparator: tDCS- SHAM Participants randomized to this arm will receive a single session of Sham tDCS for 30 minutes, delivered to supplementary motor area (SMA) or to the right (cathodal) and left (anodal) dorsolateral prefrontal cortex (DLPFC). |
Device: Sham Transcranial direct-current stimulation
A single Sham-tDCS session will be applied bilaterally over the dorsolateral prefrontal cortex (DLPFC) or over the supplementary motor area (SMA) by a DC stimulator (NeuroConn, Germany). A pair of saline-soaked sponge electrodes (surface 35 cm²) will be placed according to the International 10-20 EEG system. For SMA , one electrode (anode) will be placed 1,8 cm forward Cz and the other electrode (cathode) over the right supraorbital region. For DLPFC, electrodes will be placed over F3 (anode) and F4 (cathode). Current intensity will be ramp up for 30 seconds until reaches 2 mA, and after 30 seconds current intensity will be ramp down for 15 seconds.
