Hemiparesis
Conditions
Interventions
This is a clinical, randomized, Sham-controlled, double-blind, crossover study. With 35 individuals with Stroke that will be stimulated with Transcranial Direct Current Stimulation (ETCC) performed us
only the researcher responsible for coding the electrical stimulus will know
however, will not participate in the post-procedure evaluation and re-evaluation
Participants will be randomized to receive 4 interventions: 1- anodal tDCS (tDCS) on the left temporal cortex (T3) and
2- simulated tDCS (tDCS) on the left temporal cortex (T3) and cathode on the contralateral supraorbital region
3- anodal tDCS (tDCS) on the right temporal cortex (T4) and cathode on the contralateral supraorbital region
4- Simulated tDCS (tDCS) on the right temporal cortex (T4)

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| It is expected that the intervention will improve the sympathetic vagal balance of individuals with stroke, which will be evaluated through Heart Rate Variability (HRV), measured by a heart rate monitor (Polar® RS800 CX) in the following periods: baseline (Heart Rate Variability-1) for 10 minutes; after 6-minute walk test (6MWT) for 2 minutes (Heart Rate Variability-2), and after transcranial Direct Current Stimulation for 2 minutes (Heart Rate Variability-3). Heart Rate Variability data will be analyzed and mapped using the Heart Rate Variability Analysis program, in the Fast Fourier Transform (FFT) format and will be expressed in normalized units. After normalization, the absolute powers obtained in relation to the absolute powers obtained in the respective predefined frequency ranges: low frequency (LF) from 0.04 to 0.15 Hz and high frequency (HF) from 0.15 to 0.4 Hz | — |
Secondary
| Measure | Time frame |
|---|---|
| It is expected that the intervention will improve the Functional Capacity (FC) of individuals with stroke, the Functional Capacity will be evaluated by the 6-minute walk test (6MWT) (meters) in two moments: pre (6MWT-1) and post-transcranial Direct Current Stimularion (6MWT-2), following the standards established by the American Thoracic Society. | — |
