The purpose of this study was to assess the test-retest reliability of heart rate (HR) and velocity measurements during peak effort and free treadmill walking tests in older patients with gait-impaired chronic hemiparetic stroke and control group. Twenty-two adults (13 men, 9 women; mean age, $73.7{\pm}5.2$ yrs) with chronic hemiparetic stroke are the experimental group. Nineteen elderly people (5 men, 14 women; mean age, $72.3{\pm}3.5$ yrs) were recruited as control group. Patients had mild to moderate chronic hemiparetic gait deficits, making handrail support necessary during treadmill walking. Free and peak effort treadmill walking tests were measured and then repeated at least two days later. Reliability was calculated from HR and walking velocity during free and peak effort treadmill walking test. Among the people who had strokes, HR [ICC(2,1)=.85, r=.86] and velocity [ICC(2,1)=.93, r=.93] were good parameters during free testing. Maximal testing generated good results for HR [ICC(2,1)=.81, r=.82] and velocity [ICC(2,1)=.96, r=.96] with the chronic hemiparetic stroke. In elderly people, HR [ICC(2,1)=.59, r=.62] and velocity [ICC(2,1)=.77, r=.76] were moderately reliable during free testing. Maximal testing produced moderate parameters for HR [ICC(2,1)=.74, r=.74] and velocity [ICC(2,1)=.66, r=.66] in the elderly. This study provides that free and maximal treadmill testing produce highly reliable HR and velocity measurements in adults with chronic hemiplegia using minimal handrail support.

The aim of this study was to determine the effect of action-observation training on arm function in people with stroke. Fourteen chronic stroke patients participated in action-observation training. Initially, they were asked to watch video that illustrated arm actions used in daily activities; this was followed by repetitive practice of the observed actions for 3 times a week for 3 weeks. Each training session lasted 30 min. All subject participated 12 training session on 9 consecutive training days. For the evaluation of the clinical status of standard functional scales, Wolf motor function test was carried out at before and after the training and at 2 weeks after the training. Friedman test and Wilcoxon signed rank test was used to analyze the results of the clinical test. There was a significant improvement in the upper arm functions after the 3-week action-observation training, as compared to that before training. The improvement was sustained even at two weeks after the training. This result suggest that action observation training has a positive additional impact on recovery of stroke-induced motor dysfunctions through the action observation-action execution matching system, which includes in the mirror neuron system.

Recent advances in computer science enabled people with severe motor disabilities to use brain-computer interfaces (BCI) for communication, control, and even to restore their motor disabilities. This paper reviews the most recent works of BCI in stroke rehabilitation with a focus on methodology that reported on data collected from stroke patients and clinical studies that reported on the motor improvements of stroke patients. Both types of studies are important as the former advances the technology of BCI for stroke, and the latter demonstrates the clinical efficacy of BCI in stroke. Finally some challenges are discussed.

Objectives : This study was to compare the level of activity participation(instrumental activities, leisure activities, and social activities of living) and quality of life for elderly people with and without stroke, and to analyze the correlation between the level of activity participation and quality of life in their scores on measures. Methods : The Korean Activity Card Sort(K-ACS) was conducted among 25 elderly people with stroke and 25 elderly people without stroke living in Busan, and their level of activity participation and quality of life were evaluated using the The Medical Outcome Study 36-item Short Form Health Survey(SF-36). Results : Elderly people with and without stroke both showed a significant difference in the retained level of activity participation, instrumental activities of daily living, leisure activities, social activities, and the SF-36 score. The scores of the elderly people with stroke for the retained level of activity participation and instrumental activities of daily living in the Korean Activity Card Sort had a significant correlation with the SF-36 score, whereas leisure activities and social activities did not show a significant correlation with the SF-36 score. Among the elderly people without stroke, there was a significant correlation between scores for the retained level of activity participation, leisure activities, and social activities of living in the Korean Activity Card Sort and the SF-36 score, but there was no significant correlation between instrumental activities of daily living and the SF-36 score. Conclusion : The level of activity participation and quality of life could be considered to correlate with one another, and an intervention to improve the activity participation of elderly people with stroke would help to enhance their quality of life.

Purpose: The purpose of this study is to investigate the effect of non-invasive transcranial direct current stimulation (tDCS) on muscle activity, including 10 m WT, TUG, and BBS, in hemiplegic stroke patients. Methods: This study was conducted on 42 inpatients diagnosed with hemiplegia due to stroke at hospital B in Daejeon for more than 6 months. Walking training was conducted for six weeks, five times a week for 30 minutes, with a general walking group (14 people), tDCS walking group (14 people), and tDCS (sham) walking group (14 people). Results: As a result of the study, the change in the muscle activity before and after tDCS intervention was significantly increased in the tibialis anterior muscle in the CG group. In the EG group, the erector spine (lumbar), rectus femoris, and tibialis anterior muscles significantly increased. In the SEG group, significant increases were observed in the rectus femoris and tibialis anterior muscles. Significant differences were found in the rectus femoris and tibialis anterior muscles in the comparison between groups after intervention according to tDCS application. Also, 10 m WT, TUG, and BBS were significantly increased in the CG, EG, and SEG groups after intervention, and there were significant differences in 10 m WT, TUG, and BBS in comparison between groups after intervention according to tDCS application. Conclusion: As a result, tDCS is an effective in improving the walking ability of stroke patients, and in particular, it effectively increases the muscle activity of the rectus femoris and tibialis anterior muscles, which act directly on walking, and also improves the speed and stability of walking. It is considered being an effective method to increase the gait of stroke patients by combining it with the existing gait training.

Objective: Setting therapeutic goals assist to identify patient priorities and predict problem that may arise in performing daily and functional activities. Goal setting is associated with improved rehabilitation outcomes in individuals with hemiparetic stroke. This study was conducted to assess the effects of having awareness and satisfaction of goals on the functional status of individuals with hemiparetic stroke. Design: Cross-sectional study. Methods: Eighty-one people who had been diagnosed with stroke participated in this study. The study was conducted through a face-to-face surveys to identify participants' awareness and satisfaction of goals and standard assessment tools were used to evaluate patients' functional status. This study measured functional status through three clinical measures including the manual function test (MFT), Berg Balance scale (BBS), and modified Barthel index (MBI). Results: In participants with hemiparetic stroke, the MBI, BBS, and MFT scores were significantly higher in the participants who were aware of the therapeutic goal than in those who were unaware (p<0.05). The MBI, BBS, and MFT scores were not significant between the participants who were satisfied with the goal and those who were unsatisfied. Conclusions: This study suggests that having awareness in therapeutic goal-setting could lead to improvement of functional status in those with hemiparetic stroke. This study highlights how goal-setting can have a positive effect on persons with hemiparetic stroke.

A growing number of people are concerned about their sleep. There are many people with chronic sleep disorders. As there are various causes in a disease, proper treatment according to each cause is necessary for a more effective treatment. In general, insomnia is classified into five categories of physical, physiological, psychological, psychiatric and pharmacological aspects. Sedative-hypnotics including benzodiazepine and non-benzodiazepine have widely been used in chronic insomniacs. However, most hypnotics including non-benzodiazepine cause some of dependence, tolerance, impaired daytime function and rebound insomnia. Therefore, we are looking forward to proposing an effective oriental treatment for insomnia. A 71-year-old male who had suffered from cerebral infarction was admitted to our department for oriental treatment of stroke and insomnia. Initial treatment modalities with administration of paroxetine were not effective. However administration of oriental medicine' Gochimmuwoo-san(Gaozhenwuyou-san)' achieved a desirable effect.
