| Research Abstract |
Objectives:
The purpose of this study was to develop an objective evaluation method of swallowing for handicapped patient.
Methods:
Study 1 : Subjects; Five healthy, fully dentate (Mean age: 30.6 ア 5.9yo.)
Study 2 : Subjects; Five healthy, fully dentate (Mean age: 41.3±5.2yo.)
Study 3 : Subjects; Four handicapped people
The general-purpose ultra-sound diagnostic equipment (US) with a 5 MHz electronic convex sector scanning probe, videofluorography (VF) and endoscope (VE) were used to observe tongue movements in swallowing the test food. To record the swallowing sounds, a heart sound microphone was connected to the ultra-sound diagnostic equipment through a physiologic signal unit. The tongue movements and swallowing sounds were simultaneously recorded on DVD and analyzed by plotting five inflection points (Tl, T2, T3, T4 and T5) of the movement curve and two beginning points of swallowing sounds (S1 and S2). Subjects were directed to swallow the test food (a starch compound mixed with water or pudding)
Results:
Study 1: From the VF-image and US-image, SI coincided with the point of time that the epiglottis was just going to shut, and T4 coincided with the point of time that the tail of test food has just got to the esophagus.
Study 2: From the US-image and VE image, SI coincided with the white-out in VE-image at swallowing. After the white-out in ES-image, S2 was observed in US-image. In the empty swallowing, S2 was not observed.
Study 3: In both two subjects, S2 was not observed when the aspiration was occurred. However, they could swallow the test food without aspiration, S2 was observed.
