目的:我们的研究旨在通过比较辐照后患者和健康个体之间HD-sEMG的定量参数和地形图,探讨使用高密度表面肌电图(HD-sEMG)进行吞咽评估的可行性。
方法:招募10名健康志愿者和10名放疗后鼻咽癌患者。记录了96通道HD-sEMG,尽管每个参与者消耗的食物浓度不同(稀薄和稠的液体,果泥,粥,和软米饭)。从HD-sEMG信号的均方根(RMS)生成动态形貌,以说明吞咽过程中的前颈肌功能。通过包括平均RMS在内的客观参数评估肌肉的平均功率和吞咽模式的对称性。左/右能量比,左/右能量差。
结果:研究显示,吞咽困难患者和健康个体的吞咽模式不同。患者组的平均RMS值高于健康组,但差异无统计学意义。吞咽困难患者表现出非对称模式。
结论:HD-sEMG是一种有前途的技术,可用于定量评估吞咽困难患者颈部肌肉的平均功率和吞咽活动的对称性。

Our study aimed to investigate the feasibility of using high-density surface electromyography (HD-sEMG) for swallowing assessment by comparing the quantitative parameters and topographic patterns of HD-sEMG between post-irradiated patients and healthy individuals.
Ten healthy volunteers and ten post-irradiated nasopharyngeal carcinoma patients were recruited. 96-channel HD-sEMG was recorded although each participant consumed different consistencies of food (thin and thick liquid, puree, congee, and soft rice). Dynamic topography was generated from the root mean square (RMS) of the HD-sEMG signals to illustrate the anterior neck muscle function in the swallowing process. The averaged power of muscles and the symmetry of swallowing patterns were assessed by objective parameters including average RMS, Left/Right Energy Ratio, and Left/Right Energy Difference.
The study showed different swallowing patterns between patients with dysphagia and healthy individuals. The mean RMS values were higher in the patient group compared to the healthy group, but the difference was not statistically significant. Asymmetrical patterns were shown in patients with dysphagia.
HD-sEMG is a promising technique that could be used to quantitatively evaluate the average power of neck muscles and the symmetry of swallowing activities in patients with swallowing difficulties.
