当老年人吞咽频率下降时，怀疑与吞咽有关的器官废用性萎缩。然而，吞咽频率在老年人的日常生活中还没有被检查。我们开发了一种吞咽频率计包含喉麦克风，不限制受试者的能力，进行日常活动。在这项研究中，评估了血糖仪的实用性。实验1：检查测量仪检测吞咽的能力。指导受试者以自愿的速度吞咽唾液或食物。在这些手术过程中，通过测量仪、自计数和视频荧光造影同时记录吞咽事件。因此，所有的吞咽事件所确定的米符合吞咽事件所确定的自我计数和视频荧光。实验2：吞咽声音在个体之间和个体内部都表现出不同的模式。因此，我们检查了吞咽事件计数器计数的数量之间的一致率，并在15名受试者在一个较长的时间比实验1中的自我计数。由两名检查员计算的量表和自我计数之间的一致率在休息时分别为96.8 +/- 4.5%和98.9 +/- 3.3%，在用餐时分别为95.2 +/- 4.5%和96.1 +/- 4.1%。我们的研究结果表明，该仪器可用于测量日常情况下的吞咽频率。
Disuse atrophy of swallowing-related organs is suspected when decreased swallowing frequency is seen in the elderly. However, swallowing frequency has not been examined in elderly people during daily life. We developed a swallowing frequency meter containing a laryngeal microphone that does not restrict the subjects ability to perform daily activities. In this study, the utility of the meter was assessed. Experiment 1: The ability of the meter to detect swallowing was examined. The subject was instructed to swallow saliva or foods at a voluntarily pace. During these procedures, swallowing events were simultaneously recorded by the meter, self-enumeration and videofluorography. As a result, all of the swallowing events identified by the meter coincided with the swallowing events identified by self-enumeration and videofluorography. Experiment 2: Swallowing sounds display various patterns both between and within individuals. Therefore, we examined the concordance rate between the number of swallowing events counted by the meter and that counted by self-enumeration in 15 subjects over a longer period than in experiment 1. The concordance rates calculated by two examiners between the meter and self-enumeration were 96.8 +/- 4.5% and 98.9 +/- 3.3% at rest and 95.2 +/- 4.5% and 96.1 +/- 4.1% during meals, respectively. Our findings indicate that this meter is useful for measuring the frequency of swallowing during daily situations.
