Resumo: |
Transcranial stimulation Direct Current (ETCC) in healthy subjects can modulate the autonomic nervous system (ANS), but were not found similar studies in stroke and is characteristic of this population present cardiorespiratory changes increasing the risk to new cerebrovascular events. Objective: To evaluate the immediate effect of tDCS over the left temporal cortex the (T3) and right (T4), the cardiorespiratory parameters (functional capacity and modulation ANS) in individuals who have had strokes. Methodology: clinical trial, randomized, double blind in 20 hemiparetic. Rated Heart Rate (HR), blood pressure (BP), oxygen saturation, Borg dyspnea (D) and lower limbs, distance and heart rate variability (HRV), before and after active tDCS and sham on T3, tDCS active and sham on T4. Electrode Cathode: supra-orbital contralateral to the anode, 2mA for 20 min. Sham stimulation (30 sec). Results: tDCS on T3 in patients with left injuries decreased: HR (p???0.05), BP (p???0.05), Borg D (p???0.05) and increased distance traveled (p???0.05) and on T4 decreased: HR (p???0.05) and BP (p???0.05). Individuals with right lesion, tDCS on T3 decreased: HR (p???0.05), BP (p???0.05) and increased distance (p???0.05) in T4 BP (p???0.05). The recovery of the 6MWT after tDCS over T3 in patients with left lesion decreased sympathovagal balance (p???0.05) and on T4 (p???0.05). Individuals with right post stimuli injury on T3 and T4 decreased balance (p???0.05). Sample power was of great magnitude in individuals with injury right after tDCS over T3 (d = 1.60) compared to T4 (d = 1.41). There was no significance of HRV after active tDCS and sham on T3 and T4 at baseline. Conclusion: tDCS on T3 and T4 in the recovery of the 6MWT proved to be effective in the ANS modulation and cardiorespiratory parameters, regardless of the side of the lesion and tDCS on T3 and T4 showed no effect on basal HRV, regardless of the side of the lesion. |
