概括

在COPD患者的姿势控制任务中,肌 (scalene) (sEMG_scal) 和肌 (sternocleidomastoid) (sEMG_scm) 肌肉的表面电动图可以作为隔膜激活 (EMG_di) 的非侵入性标记物. 这为传统方法提供了一个不那么侵入性的替代方案.

科学领域:

呼吸系统生理学呼吸系统生理学
神经肌肉控制控制神经肌肉控制
肺部康复治疗肺部康复治疗

背景情况:

慢性阻塞性肺病 (COPD) 患者同时表现出姿势控制和隔膜功能受损.
传统的通过输食管电肌图 (EMG_di) 测量隔膜激活是侵入性的和昂贵的.
额外腹膜启发性肌肉表面电肌图 (sEMG) 提供了一个潜在的非侵入性替代方案.

研究的目的:

在COPD患者的姿势控制任务中,将隔膜电肌图 (EMG_di) 幅度与外隔膜鼓动肌的表面EMG幅度进行比较.
评价硬骨干肌 (sEMG_scm),骨肌 (sEMG_scal) 和副腹肋间肌 (sEMG_ic) 作为EMG_di.生理标志物的实用性.

主要方法:

九名COPD患者在不同的支面,手臂运动和呼吸条件下执行了六项姿势控制任务.
获得了EMG_di,sEMG_scm,sEMG_scal和sEMG_ic振幅的同时记录,并将其正常化为最大自愿收缩.
统计分析包括线性混合模型和Bland-Altman分析,以评估EMG信号之间的一致性和差异.

主要成果:

观察到EMG信号和姿势任务之间的显著相互作用 (p=0.0223).
经过校正后,sEMG_scal和sEMG_scm与EMG_di相比没有显著差异,并且有合理的一致性 (平均偏差分别为-3.7%和1.8%).
sEMG_ic的振幅明显低于EMG_di (p<0.0001到0.0007) 和总体偏差更高 (-20.7%).

结论:

在COPD的姿势控制评估中,面 (scalene (sEMG_scal) 和面 (sternocleidomastoid (sEMG_scm)) 肌肉表面电肌图可以作为可靠的隔膜激活 (EMG_di) 的生理标志物.
这些发现表明,COPD患者的呼吸和姿势控制功能可能会以更少的侵入性和更具成本效益的方式进行监测.
使用sEMG_scal和sEMG_scm可以减少临床和研究环境中侵入性EMG_di测量的需要.

Mechanism of Breathing III: The Accessory Muscles

The Role of Accessory Muscles in the Respiratory System
The respiratory system is a complex network that relies on primary respiratory muscles like the diaphragm, but also involves accessory muscles to enhance lung expansion and airflow during both inhalation and exhalation.
Enhancing Inhalation with Accessory Muscles:
Accessory muscles such as the sternocleidomastoid, scalene, intercostal, and abdominal muscles are crucial when additional respiratory effort is required, such as during deep...

Respiratory System Abnormal Finding I: Inspection and Percussion

Respiratory system abnormalities are a significant concern in healthcare due to their potential to indicate underlying severe conditions like Chronic Obstructive Pulmonary Disease (COPD), asthma, and pneumonia. These abnormalities can often be detected through physical examination methods like inspection and percussion.
Inspection Findings
During an inspection, several findings may suggest the presence of respiratory distress or disease. Pursed-lip breathing, where exhalation is slowed by...
