Both the PVDF sensors and accelerometers were used to detect the submental muscle activity and pharyngeal motion. They were anchored on an elastic bandage to ensure the well contact between the sensor and the skin. The signals detected by PVDF sensors and accelerometers were amplified and recorded simultaneously. The swallowing function was evaluated by using the swallowing trigger duration between the submental muscle activity and the pharyngeal motion. Ten normal male subjects without clinical evidence of dysphagia were enrolled in this study. The average age of the subjects was 25±3 y. The subjects were asked to swallow 1cc, 5cc, 20cc of 250C water, 1/3 teaspoon of pudding, 1/8 piece of soda cracker, and 5cc 250C of lemon water respectively. All subjects had adequate rest between each swallow. The result showed that the trigger duration for swallowing different volume of water reduced as the bolus volume increased with statistical significance. The trigger duration of swallowing different consistency of bolus increase as the viscosity increased. We concluded that the self-designed phagometer can be used to evaluate the swallowing function for various volume bolus and is effective in facilitating the swallowing.誌謝.................................................................................................................................I 中文摘要.......................................................................................................................II 英文摘要......................................................................................................................III 目錄..............................................................................................................................IV 表目錄..........................................................................................................................VI 圖目錄........................................................................................................................VII 第一章 緒論..............................................................................................................1 1-1 前言.........................................................................................................................1 1-2 文獻回顧.................................................................................................................3 1-3 研究動機與目的.....................................................................................................6 1-4 論文架構.................................................................................................................8 第二章 研究原理...................................................................................................11 2-1 正常吞嚥的解剖構造...........................................................................................11 2-2 吞嚥之神經控制機制...........................................................................................12 第三章 研究方法...................................................................................................18 3-1 壓力感測器之設計與原理...................................................................................18 3-1-1 PVDF壓電薄膜之特性..............................................................................19 3-1-2 PVDF壓電sensor製作方法......................................................................22 3-1-3 壓電訊號放大之電路設計與理論...........................................................22 3-1-4 濾波器之設計與理論...............................................................................26 3-2 加速度計之介紹與設計.......................................................................................27 3-2-1 加速度計之介紹.......................................................................................27 3-2-2 加速度計之電路設計...............................................................................28 3-3 影像處理系統之介紹...........................................................................................29 3-3-1 硬體架構設計...........................................................................................29 3-3-2 軟體分析方法...........................................................................................29 3-4 實驗對象...............................................................................................................30 3-5 實驗流程...............................................................................................................30 3-5-1 實驗流程...................................................................................................30 3-5-2 實驗項目...................................................................................................31 3-6資料處理與分析....................................................................................................32 第四章 研究結果與討論.....................................................................................45 4-1體積對吞嚥所造成的影響....................................................................................45 4-2 黏稠度對吞嚥造成的影響...................................................................................48 4-3 酸鹼度對吞嚥造成之影響...................................................................................48 4-4 喉部抬升之研判...................................................................................................49 4-5 實驗討論...............................................................................................................50 第五章 結論與未來展望.....................................................................................62 5-1 結論.......................................................................................................................62 5-2 未來展望...............................................................................................................63 參考文獻......................................................................................................................641564192 bytesapplication/pdfen-US吞嚥舌骨喉骨喉部抬升swallowinghyoid bonelaryngeal bonelaryngeal elevationthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/62576/1/ntu-94-R92543034-1.pdf
