Summary

To evaluate the compatibility and correlation between noninvasive surface respiratory electromyography and invasive transesophageal diaphragmatic electromyography measurements, as facilitating indicators of neural respiratory drive evaluation during treadmill exercise. Transesophageal diaphragmatic EMG (EMGdi,es) and surface inspiratory EMG, including surface diaphragmatic EMG (EMGdi,sur), surface parasternal intercostal muscle EMG (EMGpara) and surface sternocleidomastoid EMG (EMGsc) were detected simultaneously during increasing capacity exercise in stable patients with COPD. EMGdi,es, EMGdi,sur, EMGpara and EMGsc was quantified using root mean square (RMS), which represent as RMSdi,es, RMSdi,sur, RMSpara and RMSsc.

DIAGNOSTIC_TEST

Exercise testing

The test consisted of a steady-state resting period of 3 min followed by 1 min of unloaded pedaling at 60 cycles/min for each individual; the exercise load was increased by 10 W each min until the test had to be stopped because symptoms prevented further exercise. After test results were recorded, EMGdi,es and each surface inspiratory EMG of maximal exercise capacity were analysed.
