【摘要】：目的：應用表面肌電圖（Surface Electromyography，sEMG）技術(shù)與分析系統(tǒng)，探討正常受試者和腦卒中后吞咽障礙患者（post-stroke dysphagia，PSD）咽期吞咽過程中頦下肌群和舌骨下肌群肌電活動的平均振幅和持續(xù)時間的差異。方法：本實驗收集正常對照組（健康成人組，30例），病例組（PSD確診患者組，30例)，對患者臨床資料進行收集。采用芬蘭Megawin6000-T8型表面肌電圖儀采集兩組受試者在靜息狀態(tài)、空吞咽、吞咽5ml水時兩組肌群的表面肌電信號，分析出平均振幅（AEMG）和持續(xù)時間兩個指標，比較兩組之間有無統(tǒng)計學差異。結(jié)果：①靜息狀態(tài)下：病例組和對照組頦下肌群和舌骨下肌群的平均振幅均無統(tǒng)計學差異（P㧐0.05）；病例組：頦下肌群和舌骨下肌群肌電活動的平均振幅相比無統(tǒng)計學差異（P㧐0.05）；對照組：頦下肌群和舌骨下肌群肌電活動的平均振幅也無統(tǒng)計學差異（P㧐0.05）。②空吞咽狀態(tài)下：頦下肌群的平均振幅和持續(xù)時間比較，病例組較對照組平均振幅升高，持續(xù)時間延長，且具有統(tǒng)計學差異（P㩳0.05）；舌骨下肌群的平均振幅和持續(xù)時間比較，病例組較對照組平均振幅明顯升高，持續(xù)時間明顯延長，且具有統(tǒng)計學差異（P㩳0.05）；③吞咽5ml水狀態(tài)下：病例組兩組肌群肌電活動的平均振幅較對照組平均振幅顯著升高（p㩳0.005）；病例組兩組肌群肌電活動的持續(xù)時間較對照組持續(xù)時間顯著延長（p㩳0.001）；④組內(nèi)之間比較：對照組：頦下肌群和舌骨下肌群平均振幅和持續(xù)時間在空吞咽和吞咽5ml水狀態(tài)下均無統(tǒng)計學差異（P㧐0.05）;病例組：頦下肌群和舌骨下肌群平均振幅和持續(xù)時間在空吞咽和吞咽5ml水狀態(tài)下均無統(tǒng)計學差異（P㧐0.05）。 結(jié)論：sEMG技術(shù)可以作為一種無創(chuàng)、簡單、快速檢測咽期吞咽過程中相關(guān)肌群肌電活動的方法，通過頦下肌群和舌骨下肌群肌電活動的平均振幅和持續(xù)時間可以初步篩查和評估吞咽功能，反映舌骨上抬和喉上抬的難易程度和持續(xù)時間，評估患者完成此動作的神經(jīng)肌肉的功能狀態(tài)，預測吞咽障礙患者誤吸的風險。
[Abstract]:Objective: to study the surface electromyography (Surface Electromyography,sEMG) technique and analysis system in normal subjects and patients with dysphagia after stroke (post-stroke dysphagia,). PSD) the mean amplitude and duration of myoelectric activity in submental and subhyoid groups during pharyngeal swallowing. Methods: normal control group (30 healthy adults, 30 cases) and case group (PSD group, 30 cases) were collected. The surface electromyography (EMG) of two groups of subjects were collected by using Finnish Megawin6000-T8 surface electromyography in resting state, empty swallowing and swallowing 5ml water. The mean amplitude (AEMG) and duration were analyzed. There were statistical differences between the two groups. Results: (1) there was no significant difference in the mean amplitude of submental muscle group and subhyoid muscle group between the case group and the control group under resting state (P0. 05). In the case group, there was no significant difference in the mean amplitude of myoelectric activity between submental group and subhyoid group (P0. 05). The mean amplitude of myoelectric activity in submental group and subhyoid group was not significantly different (P0. 05). 2 under empty swallowing, the mean amplitude and duration of submental muscle group were higher than that of control group. The duration was prolonged and there was statistical difference (P0. 05). Compared with the control group, the mean amplitude and duration of subhyoid muscle group in the case group were significantly higher than those in the control group, and the duration was significantly prolonged (P0. 05). 3 under the condition of swallowing 5ml water, the mean amplitude of myoelectric activity in the two groups was significantly higher than that in the control group (p0. 005). The duration of myoelectric activity in the two groups was significantly longer than that in the control group (p0. 001). Comparison among the four groups: in the control group, the mean amplitude and duration of submental and subhyoid muscle groups were not significantly different under the condition of empty swallowing and swallowing 5ml water (P0. 05). In the case group, the mean amplitude and duration of submental and subhyoid muscle groups were not significantly different between empty swallowing and swallowing 5ml water (P0. 05). Conclusion: sEMG can be used as a noninvasive, simple and rapid method for the detection of myoelectric activity in pharyngeal swallowing. The mean amplitude and duration of myoelectric activity in submental and subhyoid muscles can be preliminarily screened and evaluated to reflect the degree of difficulty and duration of hyoid and laryngeal elevation. To assess the neuromuscular function of the patient who completed the action and predict the risk of misprision in patients with dysphagia.
