Stroke, not specified as hemorrahgic or ischemic.
Conditions
Interventions
Patients from both groups were submitted to only one intervention session, in which intervention group patients, with fourteen subjetcs, underwent four minutes of Virtual Reality training offered by X
in maximal voluntary isometric contraction (MVIC) and during the execution of the active movements in both groups. Electroencephalographic activity at rest and during the proposed activity was also ev

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The central excitability (EEG) evaluation, considering the right channels (HD), statistics differences for the frequency data for the FC6 channel were observed; and for the power data in the AF4 and FC6 channels for the G2-RV group, and F8 for the G1 group. In the left hemisphere (HE) and the affected side (LA) analyzes, there were changes in the neural recruitment pattern for the frequency data in channel F7 and F0 (F7 / F8) for the G2-RV group.The training with VR promoted immediate changes in central excitability, with increased neural recruitment mainly in the right hemisphere, for the channels FC6, AF4 and F8, corresponding to the pre-central, primary and frontal motor areas. ;In the peripheral excitation (EMG), statistical differences were found in the ingestion for the brachial biceps muscle (BB) (p = 0.000) and anterior deltoid muscle (AD) (p = 0.041), without intergroup alterations.;The analysis of the dynamics between central and peripheral excitation in both groups was promoted by the measure that increases central excitability (EEG), increases peripheral excitability (EMG).;Regarding the performance of the years between the minutes of execution of the game as a score attributed to each minute, the statistical difference was not observed. | — |
Secondary
| Measure | Time frame |
|---|---|
| As a secundary outcome, regarding sample homogeneity, statistical differences were observed regarding the sociodemographic variables body mass and BMI between groups G1 and G2. ;Regarding the clinical variables, the homogeneity of the sample was confirmed. This result became important so that there was no influence, mainly on the degree of neurological impairment and upper limb function, on the individuals' performance during the proposed activity, as it could influence the electroencephalographic and electromyographic activity data collected. | — |
