舌骨的垂直和向前移位是正常吞咽功能的关键生物力学组成部分。本研究的目的是评估口咽吞咽过程中舌骨的最大垂直位移和前位移。对40名不同年龄和性别的正常受试者进行了视频荧光透视吞咽检查的回顾性分析。使用ImageJ程序分析5 ml和10 ml稀液体的垂直和前向位移的平均值和标准差。年龄和性别差异进行重复测量的单因素方差分析。在吞咽过程中，年轻和老年受试者的舌骨前移位有显着差异，但垂直移位无显着差异。未观察到男性和女性受试者之间的显著差异。舌骨前移位随年龄增长而减少。这种减少可能与肌肉无力有关。然而，老年人可能会适应保持气道保护。
Vertical and anterior displacement of the hyoid bone is a critical biomechanical component of normal swallowing function. The purpose of this study was to evaluate the maximal vertical and anterior displacement of the hyoid bone during oropharyngeal swallowing. A retrospective review of video-fluoroscopic swallowing exams in 40 normal subjects varying by age and gender was performed. Means and standard deviations for both vertical and anterior displacement were analyzed on both 5-ml and 10-ml thin liquids using an ImageJ program. Age and gender differences were submitted to a repeated-measures one-way analysis of variance. There was a significant difference between younger and older subjects for anterior displacement of the hyoid bone during the swallow but not for vertical displacement. No significant differences between male and female subjects were observed. Anterior displacement of the hyoid bone decreased with increasing age. This reduction may be related to muscle weakness. However, older people may adapt to preserve airway protection.
