With the recent advances in radiological science, there was radiographic techniques development and several researches to diagnosing dysphagia. We proposed the new Imaging technology based on Near Infrared radiation (NIR) for video fluoroscopic swallowing study (VFSS). To reduce the risk of the VFSS examination for swallowing rehabilitation, multi-NIR camera system comprised. Based on the multi-NIR camera imaging system, Computational simulation was conducted to identify the potential of the multi-NIR camera imaging system as a clinical tool (screening system). As a result of the simulation applied in this study, the proposed system has a potential to be a clinical solution although there is a few of limitations. we believe that it will be a good tool to support the VFSS as a screening technology in clinical fields.

Objectives: The aim of this study is to report the effects of Korean medical treatment with electroacupuncture on post-stroke dysphagia. Methods: Two stroke patients with dysphagia received Korean medical treatment including electroacupuncture for about six months and three months respectively. A Numerical Rating Scale (NRS), Video Fluoroscopic Swallowing Study (VFSS) were used to confirm efficacy of electroacupuncture therapy as outcome measurements. Results: After treatment, swallowing function was improved, and symptoms related to dysphagia were decreased. NRS, VFSS showed improvement in stroke patients with dysphagia. Conclusions: This study shows that Korean medical treatment with electroacupuncture can be useful for dysphagia.

Dysphagia is common and serious problems in post-stroke patients. The post-stroke dysphagia with aspiration is associated with dehydration, malnutrition, pneumonia, sepsis and death. Up to date, gag reflex and choking history used to decide the aspiration in clinical. The purpose of this study was to evaluate the aspiration and to choice the proper meal formation using by video fluoroscpic swallowing study(VFSS) with post-stroke dysphagia patients. 58 post-stroke patients and ten normal person participated to perform the VFSS with liquid type, puding, yoplait, rice mixed with barium(Ba). Two rehabilitation medicine doctors and a radiological technologist analysed the phase(oral, pharyngeal, esophageal phase)with video film, and checked the pharyngeal transition time(PTT). 38 patients showed abnormality in pharyngeal phase, 13 patients in oral and pharyngeal phase, 3 patients in oral phase, and 2 patients in pharyngeal and esophageal phase. 43 patients(65.2%) occured the aspiration, but 23 of 43 patients improved by the chin tuck position. Aspiration occured 34 patients in liquid type, 2patients in rice gruel and nothing in boiled rice. After VFSS, 13 of 23 patients change the intaking pathway from nasogastric tube(NGT) to oral, On the contrary with 3 of 42 patients from oral to NGT. Consequently VFSS is clearly effective to evaluate the aspiration with post-stroke dysphagia patients.

This study was performed to examine the presence of dysphagia and analyze characteristics of the symptoms in cerebrovascular accident(CVA) patients without awareness of dysphagia. A questionnaire for this study was given to CVA patients who had visited P rehabilitation medical center in Busan. Eleven patients (4 males and 7 females) who answered no awareness of dysphasia were given to VFSS, functional dysphasia scale, and NCSE. Descriptive statistics and Pearson correlation analysis were performed by SPSS 12.0. All of subjects without awareness of dysphasia showed characteristics of dysphasia symptoms. Prominent dysfunctions were problems in oral phase and delay of swallowing reflex in pharyngeal phase. For the aspect of cognition, they showed lower score in construction, memory, and similarity than other NCSE items. There was highly significant correlation between orientation, judgment and delay of swallowing reflex. Verbal comprehension and residual materials in oral cavity showed closed correlation. CVA patients without awareness had dysphagia with high probability. The early evaluation of dysphagia should be performed in CVA patients in order to prevent complications due to CVA, so it is necessary to increase the effectiveness of rehabilitation therapy.

Swallowing disorders that can affect nutrient intakes and quality of life are commonly shown among the elderly as well as patients with neurogenic disorder. This study verifies the reliability and validity of the Swallowing Disturbance Questionnaire (SDQ), a subjective swallowing disability assessment tool, modified for Koreans' eating habit and cultural sentiment, against 105 stroke patients, in order to help identify early swallowing problems of the elderly. Reliability of internal consistency in the Korean version of SDQ is .601, test-retest reliability is .97, and concurrent validity is .956. Based on 8 points of cut-off score, 46.8% of sensitivity and 81.6% of specificity. Comparing the results of video fluoroscopic study (VFSS), an objective swallowing disorder test with those of Korean version of SDQ, negative predictive value (NPV) and positive predictive value (PPV) was shown as 81% and 53%. The Korean version of SDQ is expected to be a useful testing tool to discriminate swallowing disorders in stroke patients. It has great clinical significance in that swallowing difficulties shown by subjects can be sorted out to request a diagnostic assessment before clinical evaluation by a rehabilitation therapist or ruling out unnecessary exposure to additional tests by accurately identifying stroke patients without swallowing problems.
