研究目的：舌動態の定量解析手法を確立し，現行の舌強化訓練法・嚥下手技における舌の運動効果を定量的に検証する．さらに咽頭残留，誤嚥を認める摂食嚥下障害患者の舌動態を定量化し，症状との関連性について検討する．令和4年度の実施計画目的：舌動態の定量評価法の確立，対象：摂食嚥下障害の既往がない健常成人10名（男性5 名，女性5名）．方法：1, 舌の形態的・機能的異常の除外　舌の形態・可動域・舌小帯短縮症の有無を確認し，舌の形態的・機能的異常がないことを確認する．2, 嚥下CT撮影　撮影は320列面検出器型CTを用いて実施する．専用の椅子に被験者を着座させ，60度仰角に調整する．舌の輪郭描出を目的に被験者の舌表面をアルギン酸ナトリウム混合の希釈造影剤にてコーティングする．唾液嚥下と液体嚥下をそれぞれ1試行ずつ検者の合図で開始させCT撮影を行う．　3, CT画像処置　CT付属のソフトウェアで嚥下中の舌動態のMPR像・3D-CT像を作成する．描出された舌表面から舌の前後・左右径と体積を計測する．計測者は嚥下CTを用いた研究に精通した2名で行い，計測の信頼性を確認する．研究の進捗状況：5名の撮影を実施し，解析対象の3名の舌動態の描出並びに舌動態の定量解析を行っている．研究に関して有識者からの意見をもとに研究方法や解析方法等の修正を行いながら進めている．

Research purpose: The quantitative analysis technique of tongue dynamics has been established, and the current tongue strengthening training method and swallowing technique can quantitatively prove the effect of tongue movement. It is possible to identify and quantify the tongue dynamics of patients with dysphagia due to the presence of residue in the pharynx, and to identify and quantify the symptoms of ingestion and dysphagia. The purpose of the Reiwa 4-year treatment plan is to establish a quantitative assessment method for tongue dynamics. Target subjects: 10 healthy adults (5 males and 5 females) with past eating and swallowing disorders. Methods: 1. Exclude abnormalities in the shape and function of the tongue. Confirm the presence or absence of tongue shape, movable range, and shortening of the tongue tabula. Abnormalities in the shape and function of the tongue should be confirmed. 2. Swallowing CT imaging. The imaging technique is a 320-segment extractor-type CT scan. The exclusive chair allows the user to sit on it, and the elevation angle can be adjusted to 60 degrees. The surface of the tongue is traced out by the tongue. Swallowing saliva and swallowing liquids をそれぞれ1 Trial trial ずつ検者の合図でStart させCT imaging を行う． 3. CT image processing: CT attached to the tongue dynamic MPR image and 3D-CT image created by the swallowing medium. Trace the surface of the tongue and measure the front and back, left and right diameters and volume of the tongue. The person who measured the data is a person who has swallowed the CT and used it, studied it and is proficient in it, and the measurement is reliable and reliable. The status of the research progress: 5 people were photographed, 3 people were analyzed, and 3 people were exposed to tongue dynamics, and they were quantitatively analyzed and analyzed. Research is done, opinions of knowledgeable people are revised, research methods, analytical methods, etc. are corrected.
