Overview
Surface mechanomyography (sMMG) has been proposed as a tool to study muscle mechanical activity. sMMG is a noninvasive technique using specific transducers to record muscle surface oscillations due to mechanical activity of the motor units . It could be of major interest for the detection of respiratory efforts in patients with respiratory failure. This study aims at assessing the performances of sMMG to measure and detect respiratory drive and effort in healthy volunteers.
