目的：(1)比较健康对照和不同病因的吞咽困难患者舌骨和会厌的运动学运动情况；(2)评价吞咽运动学分析在鉴别吞咽困难发病机制方面的潜在价值。方法：我们对9例无吞咽困难的对照组、7例幕上脑卒中患者和3例出现吞咽困难的炎性肌病患者的舌骨进行了二维视频运动分析。主要观察指标为：(1)舌骨水平和垂直偏移、会厌旋转；(2)吞咽时舌骨和会厌的运动轨迹。结果：与对照组和脑卒中患者相比，肌病患者舌骨水平偏移和会厌旋转减少（P < 0.05）。吞咽困难患者在不同病因的轨迹分析中表现出与对照组不同的模式。结论：吞咽困难的病因不同，舌骨和会厌在吞咽过程中的运动程度和模式不同，吞咽运动分析可用于鉴别吞咽困难的发生机制。(C) 2006 Elsevier Ltd版权所有。
Purpose: (1) To compare the kinematic motion of the hyoid bone and the epiglottis in healthy controls and a sample of patients with dysphagia of different etiologies, and (2) to evaluate the potential value of kinematic swallowing analysis to differentiate the mechanism of dysphagia.Methods: We performed two-dimensional video motion analysis of the hyoid bone using videofluoroscopic images in nine controls without any swallowing difficulty, and seven patients with supratentorial stroke, three patients with inflammatory myopathy who showed dysphagia. Main outcome measures were: (1) horizontal and vertical excursion of the hyoid bone, and rotation of the epiglottis, and (2) trajectory of the hyoid bone and epiglottis during swallowing.Results: Horizontal excursion of the hyoid bone and rotation of the epiglottis were reduced in patients with myopathy as compared to control and patients with stroke (P < 0.05). Patients with dysphagia showed different patterns as compared to control in trajectory analysis according to their etiology.Conclusion: We conclude that extent and pattern of movement of the hyoid bone and the epiglottis during swallowing were different according to etiology of dysphagia, and swallowing motion analysis could be applied to differentiate the mechanism of dysphagia.
