Previous studies found important function of brain in exercises regulation on healthy and athlete patients and this studies showed not invasive stimulation on temporal cortex brain, induces electrics field to insula cortex, in addition modulate autonomic nervous system cognition efforts during submaximal (maximal hight frequency) and maximal exercises. Measure immediate effects of transcranial stimulation in bloodstream (tDCS) anodic on right and left temporal cortex in the cardiorespiratory parameters (functional capacity, perception of efforts and modulation of autonomic nervous system) in patients with hemiparesis due stroke. Methods and Material: It Is a clinical trial, controlled and Double blind, using 30 adult patients with stroke sequel, like roam. Evaluation will be hemodynamic measure data such as: Heart Rate, Respiratory Rate, Blood Pressure, Lung Capacity Vital and assessment of the Autonomic Nervous System, before and after anodic electro stimulation from bloodstream on right and left temporal cortex region (T3 area) and cathodic position in contralateral supraorbital region to anode (Fp2). On temporal cortex will be applied of 2mA during stimulation of 20 minutes. Sham stimulation all electrodes Will be used. The stimulator turns on for 30 seconds. Results: The primary results will analyze cardiac frequency before and after tDCS and second step will assess the travelled distance on walking test for 6 minutes with and without tDCS and compare these respiratory reviews results with stroke gravity.
