评价无创性体表呼吸肌电图和有创性经食管呼吸肌电图测量作为平板运动中神经呼吸驱动（NRD）评价的促进指标之间的兼容性和相关性。对20例稳定期COPD患者在提高运动能力过程中同时进行经食管吸气肌肌电图（EMGdi，es）和表面吸气肌肌电图（EMGdi，sur）、表面胸骨旁肋间肌肌电图（EMGpara）和表面胸锁乳突肌肌电图（EMGsc）的检测。使用均方根（RMS）对EMGdi，es、EMGdi，sur、EMGpara和EMGsc进行定量，并分别表示为RMSdi，es、RMSdi，sur、RMSpara和RMSsc。COPD患者运动时EMGdi，es与EMGdi，sur（r=0.966，p<0.01）、EMGpara（r=0.967，p<0.01）、EMGsc（r=0.956，p<0.01）之间存在显著相关。Bland-Altman图显示，与EMGdi，es和其他两个EMG参数之间的偏倚值相比，EMGdi，es和EMGpara之间的平均偏倚值最低。在比较EMGdi，es的估计值时，我们观察到最低偏倚值（−1%）和一致性值的最低限值（−10%至−12%）。EMGdi，es与EMGdi，sur、EMGdi，es与EMGpara、EMGdi，es与EMGsc的组内相关系数（ICC）分别为0.978（p <0.01）、0.980（p<0.01）、0.868（p<0.01）。RMSdi、sur、RMSpara和RMSsc可作为COPD患者NRD的生理学指标。在稳定期COPD患者中，RMSpara与平板运动期间的经食管肌电图显示出最佳的兼容性和相关性。
To evaluate the compatibility and correlation between noninvasive surface respiratory electromyography and invasive transesophageal diaphragmatic electromyography measurements as facilitating indicators of neural respiratory drive (NRD) evaluation during treadmill exercise. Transesophageal diaphragmatic electromyogram activity (EMGdi,es) and surface inspiratory electromyogram (EMG) activity, including surface diaphragmatic EMG activity (EMGdi,sur), surface parasternal intercostal muscle EMG activity (EMGpara), and surface sternocleidomastoid EMG activity (EMGsc), were detected simultaneously during increasing exercise capacity in 20 stable patients with COPD. EMGdi,es, EMGdi,sur, EMGpara, and EMGsc were quantified using the root mean square (RMS) and were represented as RMSdi,es, RMSdi,sur, RMSpara, and RMSsc, respectively. There was a significant association between EMGdi,es and EMGdi,sur (r=0.966, p<0.01), EMGpara (r=0.967, p<0.01), and EMGsc (r=0.956, p<0.01) in the COPD patients during exercise. Bland-Altman plots showed that the lowest mean bias value was between EMGdi,es and EMGpara compared with the bias values between EMGdi,es and the other two EMG parameters. In comparing the estimation of EMGdi,es, we observed the lowest bias values (−1%) and the lowest limits of agreement values (−10% to −12%). Intraclass correlation coefficient (ICC) between EMGdi,es and EMGdi,sur was 0.978 (p<0.01), between EMGdi,es and EMGpara was 0.980 (p<0.01), and between EMGdi,es and EMGsc was 0.868 (p<0.01). RMSdi,sur, RMSpara, and RMSsc could provide useful physiological markers of NRD in COPD. RMSpara shows the best compatibility and correlation with transesophageal diaphragmatic electromyography during treadmill exercise in stable patients with COPD.
