项目摘要

This study was aimed to develop the tongue pressure measurement procedure as a diagnostic system of dysphagia in the elderly. We used an originally developed sensor sheet system for measuring tongue pressure dining swallowing in the healthy subjects and dysphagic patents with stroke or Parkinson's Disease. As results of analysis of the state of tongue pressure production during swallowing, we found a lot of findings which could be the basis for developing diagnostic criteria of dysphagia as bellows.1. It was secured that our sensor sheet system could be used for tongue pressure measurement like as an experimental palatal plate with pressure sensors.2. There were differences in the tongue pressure production during swallowing between young adult subjects and elderly subjects. Maximal magnitude of tongue pressure along the median line in the elderly was smaller than that in young adults. Duration of tongue pressure at each sensing point in the elderly was longer than that in young adults.3. Maximal tongue pressure during swallowing in the paralyzed side of acute stroke patients was smaller than that in non-paralyzed side.4. Maximal tongue pressure during swallowing at the posterior-circumferential part in patients with Parkinson's Disease was smaller than that in normal subjects. Duration of tongue pressure at each sensing point in patients with Parkinson's Disease was shorter than that in normal subjects.5. These findings suggested the possibility of developing diagnostic criteria of dysphagia by tongue pressure measurement.6. There was a sequential coordination among tongue pressure production, EMG activity of swallow related muscles and swallowing sound, which suggested the possibility of comprehensive evaluation system of oro-pharyngeal swallow.

本研究的目的是发展舌压测量程序作为老年人吞咽困难的诊断系统。我们使用了一个最初开发的传感器片系统测量舌压力用餐吞咽在健康受试者和吞咽困难的中风或帕金森氏病患者。通过对吞咽过程中舌压产生状态的分析，我们发现了许多可以作为制定吞咽障碍诊断标准的依据.我们的感测片系统可以像实验性的腭板压力感测器一样用于舌压测量.在吞咽过程中，年轻成人受试者和老年受试者之间的舌压产生存在差异。舌压最大值沿着中线在老年人小于年轻人。老年人舌压各感觉点持续时间均长于青年人.急性脑卒中患者瘫痪侧吞咽时最大舌压小于非瘫痪侧.帕金森病患者吞咽时舌后环部最大压力小于正常人。帕金森病患者舌压各感觉点持续时间短于正常人.这些结果提示了通过舌压测量建立吞咽障碍诊断标准的可能性.舌压的产生、吞咽相关肌群的肌电活动和吞咽音之间存在着序贯的协调关系，提示建立口咽吞咽综合评价系统的可能性。
