The purpose of this study was to investigate the effects of direct swallowing treatment on recovering swallowing functions and quality of life. The study was performed over three weeks from December 3 to 21, 2012 for one dysphagia patient who was diagnosed with a stroke. The study design was carried out using a reversal design (AB) in single-subject experimental research. The direct swallowing treatment were implemented by a total of 10 times, five times a week and 20 minutes for each treatment, and the results of the treatment were compared and analyzed based on the differences in scores during the treatment period of the baseline and swallowing treatment. After completing the direct swallowing treatment, the swallowing function in stroke patients was improved and the improved swallowing function affected the quality of life positively. Based on the results of this study, it is necessary to make efforts to improve the swallowing function and quality of life in patients through applying such early direct swallowing treatment with oral intakes for the subjects who can take direct swallowing treatment in clinics.

The purpose of this study was to analyse the effects of yoga exercise on balance ability and gait velocity in stroke patients. Subjects were categorized in to a control group and yoga program group with 9 for each group. Yoga program was conducted for 60minute for 8weeks, three times a week. For the purposes, the study measured Stability Index(SI, postural sway) and Weight Distribution Index(WDI) using Tetrax, Functional Reach Test(FRT), Dynamic Gait index(DGI) and 10 meter walking test. At pre- and post-exercise after appling the yoga exercise, the data was analyzed. Yoga exercise group's SI and WDI were decreased, FRT and DGI were increased in comparison with control group. But 10 meter walking test was no significance. It suggests that the yoga exercise could promote recovery from balance disorder after stroke.

최근 MR영상을 허혈성 뇌졸중의 초급성기에 뇌조직의 관류 이상을 조기에 진단하려는 연구들이 진행되고 있으나 아직 일반적인 진단용 소프트웨어만 있을 뿐 영상 자료를 후처리하여 뇌조직의 구조 및 기능적인 정보를 제공하는 mapping 영상을 특수 소프트웨어는 실용화되어 있지 않다. 본 논문에서는 Gamma-variate 곡선 정합을 이용한 뇌관류 파라미터 영상 mapping의 알고리즘 구현에 관해 연구하였다. 관류 MR영상의 각 화소마다 측정된 시간에 따른 신호강도의 변화 곡선은 비선형적이어서 뇌관류에 관한 여러 가지 혈역학적 변수들을 보다 정확하게 계산할 수 없었다. 그래서 수렴속도가 빠르고 안정성이 높은 비선형 최적화 알고리즘인 Levenberg-Marquardt 알고리즘(LMA)을 활용하였다. 즉 시간에 따른 신호강도의 변화 곡선을 Gamma-variate 함수를 이용하여 곡선 정합한 후, CBV, MTT, CBF, TTP, BAT, MS의 여러 가지 혈역학적 변수를 LMA에 의해 계산하였다. 그 결과로 관류 MR영상으로부터 얻은 mapping 영상은 초급성 허혈성 뇌졸중에서 관류에 관한 혈역학적 변화를 평가함으로써 나중에 생길 뇌경색의 범위를 예견하는 데에 유용하였다.

The purpose of this study was to compare the effectiveness of rehabilitation therapy with natural recovery in patients who had dysphagia due to stroke. Swallowing functions were examined on a total of 98 patients with stroke-caused dysphagia based on a videofluoroscopic swallowing study (VFSS) for 8 weeks. The each group was evaluated with DOSS, DSS and FOSS to assess swallowing ability in the first week and re-evaluated in the $8^{th}$ week during the session for investigating the recovery status. The author compared the above initial data and follow-up data using a Mann-Whitney U test, Kruskal-Wallis test and Wilcoxon's Signed Rank test, ANCOVA to confirm statistically controlling for the effects of other continuous variables, performed by IBM SPSS Statistics 20.0 for windows. There was statistically significant recovery in the experimental group except measure of DOSS (p>0.05). In the control group, it showed improvement in all the scales(p<0.05). After terminating each session, the comparison of the two group of patients showed statistical significant differences in DSS and FOSS(p<0.05). These results suggest that possibility of natural neurologic recovery has positive effects on early stage of dysphagia caused by stroke.

Purpose : The purpose of this study was to identify the effect of recovery of disability on post-stroke depression in stroke patients. Methods : Fifty patients with stroke were participated in this study. The stroke impact scale(SIS) was used to assess the recovery of disability according to stroke and short form of geriatric depression scale(SGDS) was used to assess the poststroke depression(PSD). Results : The suspicious for depression were exhibited in 38%(n=19) and patients with depression were 58% (n=26) of 50 patients with stroke. In correlation between recovery of disability and depression, emotion and recovery of stroke negatively correlated with depression(p<.05). Conclusion : These results demonstrates that patients with stroke need to manage and treat emotion for the prevention and management of PSD.
