健康老年人舌骨的运动学研究

Study of hyoid motion during swallowing in normal elder

目的探讨食物黏稠度、性别对正常老年人吞咽时舌骨运动功能的影响。方法选取 60例健康老年人进行电视X线透视吞咽功能检查 ,分别比较性别、食团黏稠度对受试者吞咽时舌骨运动的时间与空间参数的影响。结果老年男性吞咽时舌骨的运动时间长于老年女性 ,舌骨向上、向前运动幅度大于老年女性 (P <0 .0 5 ) ;吞咽 3种不同黏稠度食团时 ,舌骨向前运动幅度无显著性差异 ;吞咽液体时 ,舌骨向上运动幅度明显小于半固体与固体食物 (P <0 .0 1) ,而吞咽半固体与固体食物之间无显著性差异。舌骨运动时间随食物黏稠度增加而增加。结论吞咽时 ,舌骨的运动包括向上及向前运动 ,食团黏稠度主要影响舌骨的向上运动 ,不同性别舌骨的运动时间与幅度不同。

ObjectiveTo explore effects of food viscosity and sex on hyoid motion during swallowing in normal elder.MethodsVideofluoroscopic studies were done in 60 healthy elder. Hyoid motion during swallowing food with different viscosity was measured.ResultsOlder male had longer movement duration, greater amplitudes of upward and forward movement than older female ( P<0.05). Amplitudes of upward movement in jam thick swallow and bread thick swallow were greater than that in liquid swallow ( P<0.01) . Bread thick swallow had the longest movement duration; liquid swallow had shortest movement duration.ConclusionThe hyoid bone moves both upward and forward during swallowing, the amplitude of upward displacement is highly variable and influenced by food viscosity. The duration and amplitude of hyoid motion in male or female are different. [
