Study Overview
Brief Summary
The present study aims at enhancing our understanding of the influence of the mouthpiece configuration on the amplitude of oral pressures generated during a maximum expiratory pressure maneuver and on the neuromuscular recruitment of expiratory muscles (more specifically of the internal oblique and the transverse abdominal muscles).
Detailed Description
Enhancing our understanding of the influence of the mouthpiece configuration on oral pressures and on the neuromuscular recruitment of the internal oblique and the transverse abdominal muscles during a maximum expiratory pressure (MEP) maneuver is the primary goal of this study
Maximal Respiratory Mouth Pressures (MIP and MEP):
Maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) are commonly used indices to assess respiratory muscle strength at the mouth.
MIP measures the strength of inspiratory muscles, while MEP assesses expiratory muscle strength.
These measurements are simple, convenient, and noninvasive. However, clear standards for these measurements are not well-established.
