探讨同时进行高分辨率咽部测压(HRM)和肌电(EMG)实验范式的可行性，以检测呼气训练期间咽部、喉部和咽部肌肉活动的吞咽相关模式。技术报告。两名健康受试者在五个任务中同时获得了HRM、表面肌下肌电和肌内肌电：10cc吞水、最大呼气压力(MEP)测试和三种压力水平(假手术、50%和75%MEP)下的呼气肌力训练(EMST)。实验条件是可行的。腭咽闭合压、腭部肌电活动和咽部肌电活动随着呼气负荷的增加而增加。相反，在呼气任务中，甲状旁肌的肌电活动较低，这与呼气时的声门打开相一致。在呼气任务中，智下肌电模式变化更大。用HRM记录的腔内气压与测量的呼气压力和EMST装置的目标瓣膜开启压力相关。结果表明，同时的HRM/EMG/Emst范式可用于检测Emst过程中先前未量化的吞咽相关肌肉活动，特别是在腭部和咽部。我们的方法和初步发现将有助于指导未来以假设为导向的研究，并可能使研究人员能够评估在这些任务中活跃的其他肌肉群。确定作用机制是完善治疗算法的关键下一步，使用Emst和其他针对吞咽困难和呼吸道疾病人群的靶向治疗。
To examine feasibility of a simultaneous high-resolution pharyngeal manometry (HRM) and electromyography (EMG) experimental paradigm to detect swallowing-related patterns of palatal, laryngeal, and pharyngeal muscle activity during expiratory training. Technical report. Simultaneous HRM, surface submental, and intramuscular EMG were acquired in two healthy participants during five tasks: 10-cc water swallow, maximum expiratory pressure (MEP) testing, and expiratory muscle strength training (EMST) at three pressure levels (sham, 50%, and 75% MEP). Experimental conditions were feasible. Velopharyngeal closing pressure, palate EMG activity, and pharyngeal EMG activity increased as expiratory load increased. In contrast, thyroarytenoid EMG activity was low during the expiratory task, consistent with glottic opening during exhalation. Submental EMG patterns were more variable during expiratory tasks. Intraluminal air pressures recorded with HRM were correlated with measured expiratory pressures and target valve-opening pressures of the EMST device. Results suggest that a simultaneous HRM/EMG/EMST paradigm may be used to detect previously unquantified swallowing-related muscle activity during EMST, particularly in the palate and pharynx. Our approach and initial findings will be helpful to guide future hypothesis-driven studies and may enable investigators to evaluate other muscle groups active during these tasks. Defining mechanisms of action is a critical next step toward refining therapeutic algorithms using EMST and other targeted treatments for populations with dysphagia and airway disorders.
