To accomplish the study it was assessed a group of 12 post-stroke patients who were admitted in the Rehabilitation Clinic inside the University. As inclusion criteria it was established to be able to walk alone without supervision and with no aids.

All the patients signed an informed consent before performing the tests. To characterize the sample it were used the Fugl-Meyer scale, Orpington test, Mini Exam of the Mental State and some other data regarding the age, gender, type of the lesion and side of the lesion.

The 6 Minute Walk Test (6MWT) was conducted in a level corridor 30 meters long and 5 meters wide. Before and after testing were measured O2 saturation (SatO2) and heart rate (HR), respiratory rate (RR), blood pressure (BP), the Double Product (DP), a measure of myocardial oxygen consumption, was calculated as the product of HR and systolic BP, and the sensation of dyspnea and fatigue of the lower limbs using the Borg scale, and performing the record turns traveled, each 30 meters is considered a covered back. To calculate the predicted distance, the investigators use the formula described by American Thoracic Society (ATS) knowing the weight, age and height of participants. The Step Test (ST) was conducted in six minutes for it to be compared to the 6MWT.

Will be assessed Blood Pressure (BP), Heart Rate (HR), Breathing, Feeling of fatigue and dyspnea with the Borg scale, and the Double Product.

Will be evaluated through the correlation between the number of ascents on the step and the distance covered in walking test.
