摘要

目的：本研究擬探討正常老化、性別以及食物種類對吞嚥功能造成的影響。方法：總共有100位年齡介於24歲到80歲的個案參與本研究,男女各半。研究使用固定在喉頭的表面記錄電極記錄乾吞口水及吞食不同種類食物時喉頭的位移狀況。主要的評估參數包括吞嚥波的平均潛伏期、振福及間期。結果：研究顯示，所有個案乾吞口水時吞嚥波的平均潛伏期與喝水及吃餅乾時有顯著差異，但與吃布丁時沒有差別。事實上，乾吞口水時吞嚥波的平均潛伏期及振幅均大於進食其他種類的食物。喝冰水及溫水時吞嚥波的平均潛伏期不管在年輕及年長個案組均無顯著差異。61-80歲這組個案吞嚥時的平均潛伏期顯著比年輕的個案來得長。而男性不管在吞食何種食物黏度的吞嚥波振福均顯著大於女性，其中又以21-40歲的年輕男性這組與女性的差異最為明顯。結論：吞嚥治療時常用的乾吞口水並不是容易進行的技巧，而吞嚥反射在60歲以上的個案顯著慢於年輕的個案；另外，正常的老化並不太影響吞嚥的力量，尤其是女性個案。（台灣復健醫誌2012；40（1）：1-7）

Objective: The purpose of this study was to investigate the physiologic changes of swallowing along with normal aging, and to study the influences on swallowing of gender and food consistency.Methods: One hundred adult men and women aged 24 to 80 participated. Each subject underwent a swallowing evaluation, in which a surface transducer was placed on the neck to detect laryngeal movement when they performed a dry swallow and wet swallow for different food consistencies. Main outcome measures included mean onset, mean amplitude and mean duration of the deglutition wave.Results: In this study, the onset of the dry swallow deglutition wave reached statistical difference with warm water, ice water and cookie swallows, but not with a pudding swallow. Prolonged onset and largest amplitude of deglutition wave were actually observed during dry swallow. There was no significant difference between the onset of the deglutition wave following the ice water and warm water swallow for each age group. The onset of deglutition for the subjects aged 61-80 was slower than for the younger subjects. The male subjects revealed significantly larger amplitude of deglutition wave than the females for each food consistency. The 21-40 year-old male subjects had significantly larger deglutition wave amplitude with the dry swallow; warm water and cookie swallow than the female groups.Conclusion: Our results suggest that even among normal populations, dry swallowing is not an easy task to do. Slowing of the initiation of swallowing reflex might begin as early as 60 years old. And, aging alone does not significantly affect the strength of oral pharyngeal muscles particularly in female population. (Tw J Phys Med Rehabil 2012; 40(1): 1 - 7)
