Effects of Age and Gender during Three Lingual Tasks on Peak Lingual Pressures in Healthy Adults
Elizabeth(Elizabeth Rachel Oommen),Youngsun Kim 한국언어재활사협회 2018 Clinical Archives of Communication Disorders Vol.3 No.2
Purpose: This study examined the effects of age and gender during three intra-oral lingual tasks (elevation, protrusion, and depression) on peak lingual pressure in healthy adults. Methods: Healthy adults were divided into groups based on age, young (18 to 35 years) and older (>60 years) adults, and gender. All the 49 participants completed maximum isometric pressure intraoral lingual tasks (elevation, protrusion, and depression) and peak anterior lingual pressures were recorded using the three-bulb tongue array of the Digital Swallowing WorkstationTM. Peak lingual strength was recorded as the average of peak lingual pressures of the three trials for each lingual task. A three-way ANOVA, where the independent variables were age, gender, and lingual task, was conducted to determine the effects on the dependent variable, peak lingual pressure. Results: Younger adults were found to exhibit significantly greater peak lingual pressure when compared to older healthy individuals, while no differences in peak lingual pressures were observed between men and women. Among the three intraoral lingual tasks, peak lingual pressures were highest during lingual depression and least during lingual protrusion. Conclusions: The effects of age, gender, and lingual task on peak anterior lingual pressure, and the applicability of such lingual tasks in lingual strengthening exercises are discussed.

The Effects of Bolus Consistency in Pharyngeal Transit Duration during Normal Swallowing
임익재,김영선,Elizabeth Oommen,김현기,고명환 대한재활의학회 2012 Annals of Rehabilitation Medicine Vol.36 No.2
Objective To examine the eff ects of age, gender and bolus consistency in normal populations using the temporal measurement of Pharyngeal Transit Duration (PTD), which refl ects the duration of bolus fl ow from the ramus of the mandible to the upper esophageal sphincter. Method 40 normal and healthy subjects had Videofl uoroscopic Swallowing Examinations (VFSEs) of 5 ml thin and nectar thick liquids, and puree consistencies. A slow motion and frame by frame analysis was performed. Th reeway analysis of variance (ANOVA) was performed to examine the main eff ect and interactions, and paired t-tests for the three consistency comparisons. Results Older subjects had a significantly longer PTD than younger subjects (p<0.01). In addition, men had significantly shorter PTDs than women (p<0.01). Puree showed a significantly longer PTD than the other two consistencies, regardless of age and gender (p<0.05). Conclusion PTD is an indicative of motor weakness in pharyngeal swallowing secondary to aging. In addition, the results supported the assumption that there is a functional diff erence in pharyngeal swallowing between men and women. It is expected that the results of this study will be used for further investigation of patients with dysphagia.

The Effects of Bolus Consistencies on the Swallowing Safety in Poststroke Patients

배경 및 목적: 진한 액체나 퓨레 음식은 병원이나 요양원의 삼킴장애 환자에게 가장 많이 쓰이는 보상치료방법이다. 본 연구의 목적은 흡인을 보이는 뇌졸중 환자가 다양한 음식점도(묽은 액체, 진한 액체, 퓨레)를 삼켰을때 삼킴안전에 변화를 보이는지와 다양한 음식 사이에는 삼킴안전에 차이를 보이는지 알아보는 것이다. 방법: 뇌졸중 환자 24명 중 묽은 액체에서 흡인을 보인 환자 12명의 비디오투시조영검사 자료에서 각 환자의 5 mL의 묽은 액체, 진한 액체, 퓨레의 삼킴을 분석하였다. 본 연구에서 삼킴의 안전을 측정하기 위해 사용한 침습-흡인 척도는 1에서 8점 척도이다. 자료분석을 위해 일원분산분석(one way ANOVA)을 실시하였고, 유의수준은 .05로 설정하였다. 결과: 흡인을 보이는 뇌졸중 환자의 경우 음식점도에 따라 침습-흡인 척도에서 유의미한 차이를 보였다(p<.01). 흡인을 보이는 뇌졸중 환자의 묽은 액체와 진한 액체, 묽은 액체와 퓨레에서 침습-흡인 척도의 감소가 나타났고(p<.01), 진한 액체와 퓨레 사이는 유의한 차이를 보이지 않았다(p=.55). 논의 및 결론: 본 연구를 통해서 다음의 두 가지 임상적 의의를 생각해 볼 수 있다. 첫째, 묽은 액체에 흡인을 보이는 환자라 할지라도 진한 액체나 퓨레로 대체하여 액체나 음식을 안전하게 삼킬 수 있다. 둘째, 환자에게 묽은 액체를 대체할 것을 선택 시 진한 액체와 퓨레는 삼킴안전에 차이가 없다는 것이다. Objectives: Thickened liquids or pureed foods are one of the most frequently used compensatory strategies in hospitals and long-term care facilities for patients with dysphagia. The purpose of this study was to determine whether different bolus consistencies (thin liquid, nectar thick liquid, and puree) would improve the safety of swallowing and whether there would be a difference within these consistencies on swallowing safety in poststroke patients. Methods: Videofluoroscopic swallowing examinations (VFSEs) were obtained from 24 poststroke patients. Among them, 12 poststroke patients showed aspiration in thin liquid. VFSEs of these patients were advanced to swallowing nectar thick liquid and puree. To determine the safety of swallow in changes of bolus consistency, penetration-aspiration scale (P-A scale) was used to rate the swallow on a scale of 1 to 8. Statistical comparisons were made by one-way analysis of variance (ANOVA), and the significance level was set at p<.05. Results: For poststroke patients with aspiration, change in bolus consistency had a significant effect on the P-A acale rating (p<.01). The poststroke patients with aspiration exhibited significant decreases in P-A scale between thin liquid and nectar thick liquid and between thin liquid and puree (p<.01), but not between nectar thick liquid and puree (p=.55). Conclusion: The findings have two clinical implications. First, thickened liquid or puree provided an alternative way to obtain liquid or food safely to poststroke patients who aspirated thin liquids. Second, there is no difference on swallowing safety between nectar thick liquids and puree in poststroke patients with aspiration.
