Purpose This study is aiming to examine the impact of the Oral Stereognosis Training(OST) on the Oral Stereognosis Ability(OSA), tongue sensory and swallowing ability targeting the stroke patients with a dysphagia. Methods The study is carried out with the subjects comprised of 24 patients by classifying them into two study groups, the experimental group of 12 patients and the control group of 12 patients who are all diagnosed with the dysphagia after having stroke and currently being. The OST and traditional swallowing treatments have been applied as intervention Methods. In order to figure out the OSA and reaction time for searching diagrams, the Oral Stereognosis Ability Test(OSAT) has been adopted, and the Semmes Weinstein Monofilament(SWM) has been utilized to examine the sensory of a tongue. finally, Videofluoroscopic Dysphagia Scale(VDS) based on the picture of Video Fluoroscopic Swallowing Study(VFSS) has been measured to find out the swallowing ability. Results The experimental group received oral Stereognosis Training had a significant difference in oral Stereognosis score and response time.(p<.01, p<.05) The experimental group received oral stereognosis training showed significant differences in tongue light touch.(p<.01) In addition, the experimental group received oral stereognosis training showed a significant difference in swallowing ability(p<.01). Conclusion The study discussed so far demonstrate that the OST, targeting the stroke patients with a dysphagia, has some positive influence on improving the OSA, the sensory of a tongue and the swallowing ability.
