目的：本研究比较了经皮电刺激（TES）幅度对健康的年轻人和老年人吞咽过程中舌腭和咽部峰值压力的时间的影响。背景：经皮电刺激幅度是一个参数，可能对神经运动系统和吞咽生理有不同的影响。受年龄影响的吞咽生理学的一个方面是吞咽事件的时机。然而，不同的TES振幅吞咽生理的时间上的影响知之甚少，特别是在老年adults.Materials和方法：三十四名成年人（20年轻和14岁以上）吞咽10毫升的花蜜稠液体在三个TES条件：无刺激，低振幅刺激和高振幅刺激。TES通过前颈部的表面电极递送。结果：舌根（BOT）和下咽部（HYPO）存在显著的年龄×刺激幅度相互作用[F（2，62）= 5.087，p <0.009]。在BOT，低振幅TES导致更慢的吞咽在年轻的成年人相比，没有TES。在老年人中，低振幅TES导致吞咽速度比高振幅TES快。在HYPO时，两个年龄组的三个TES振幅之间的压力计时没有显著差异。在每一种情况下，低振幅TES导致更快的吞咽在老年人与年轻adults.Conclusions：经皮电刺激影响咽部压力的时间不同的年轻人和老年人，这问题的适当性使用一个尺寸适合所有的' TES振幅康复吞咽困难的人。
Objectives: This study compared the effect of transcutaneous electrical stimulation (TES) amplitude on timing of lingual-palatal and pharyngeal peak pressures during swallowing in healthy younger and older adults.Background: Transcutaneous electrical stimulation amplitude is one parameter that may have different impacts on the neuromotor system and swallowing physiology. One aspect of swallowing physiology influenced by age is the timing of swallowing events. However, the effect of varying TES amplitudes on timing of swallowing physiology is poorly understood, especially in older adults.Materials and methods: Thirty-four adults (20 younger and 14 older) swallowed 10 ml of nectar-thick liquid under three TES conditions: no stimulation, low-amplitude stimulation and high-amplitude stimulation. TES was delivered by surface electrodes on the anterior neck. Timing of pressure peaks for lingual-palatal contacts and pharyngeal pressures were measured under each condition.Results: A significant age x stimulation amplitude interaction was identified for the base of tongue (BOT) [F(2,62) = 5.087, p < 0.009] and the hypopharynx (HYPO) [F(2,62) = 3.277, p < 0.044]. At the BOT, low-amplitude TES resulted in slower swallows in the younger adults compared with no TES. In older adults, low-amplitude TES resulted in faster swallows compared with high-amplitude TES. At the HYPO, no significant differences were identified in pressure timing across the three TES amplitudes in both age groups. In each case, low-amplitude TES resulted in faster swallows in older adults compared with younger adults.Conclusions: Transcutaneous electrical stimulation influences pharyngeal pressure timing differently in young and old people, which questions the appropriateness of using a one-size-fits-all' TES amplitude for rehabilitating people with dysphagia.
