Acute Effects After Stretching Respiratory Muscles on Ventilatory Pattern and Volume Distribution of Chest Wall

Completed

Phase N/A Results N/A

Trial Description

The purpose of study is to evaluate the acute effects of respiratory muscles stretching on ventilator pattern and volume distribution of chest wall in patients with right hemiparesis post-stroke and our hypothesis is that the use of RMS will be able to improve changes in the respiratory function.

Detailed Description

All study protocol will be performing in three different days. In the first day, the participants will undergo to the initial assessment, which consisted of anamnesis and anthropometric measurements: weight, height and body mass index (BMI). Then, they will be submitting to spirometry and respiratory muscle pressure using a manovacuometer.
All patients will submit underwent two types of intervention: respiratory muscles stretching (RMS) and remain at rest (control group). The stretching will occur throughout the expiratory phase to allow respiratory muscles to reach their maximal length, and two sets with 10 consecutive incursions will use for each stretching pattern with an interval of 30 seconds between series.
For the intervention in the control group, all volunteers will be position at rest in a comfortable in a chair during 20 minutes.
