A reliable M-mode ultrasound protocol for the assessment of diaphragm motion. Chest. 2014;145(3 Suppl):463A.http://hdl.handle.net/10400.21/4736Diaphragm is the principal inspiratory muscle. Different techniques have been used to assess diaphragm motion. Among them, M-mode ultrasound has gain particular interest since it is non-invasive and accessible. However it is operator-dependent and no objective acquisition protocol has been established. Purpose: to establish a reliable method for the assessment of the diaphragmatic motion via the M-mode ultrasound.engUltrasoundM-modeDiaphragmatic motionRehabilitationconference object10.1378/chest.1822202
