Objectives : Metabolic syndrome (MetS) is associated with increasing risk of cardiovascular morbidity and mortality but the risk of stroke associated with the MetS is less well established. The objective of this study was to evaluate the prevalence of MetS in stroke patients. Methods : We analyzed the data of 806 patients with acute ischemic stroke from Hanbang Stroke Registry supported by the Ministry of Science and Technology of Korea. Subjects' enrollment was done in the oriental medical hospitals of 4 universities located in the metropolitan region from April 2007 to August 2008. We analyzed all registered data and evaluated the prevalence of MetS and specific components of MetS. Results : The prevalence of MetS in stroke patients according to American Heart Association/National Heart Lung and Blood Institute (AHA/NHLBI) criteria was 59.6%. The prevalence according to the International Diabetes Federation (IDF) criteria was 41.6%. The prevalence of female patients was higher than that of male patients (71.8% vs 51% by AHA/NHLBI criteria; 61.7% vs 27.7% by IDF criteria). The prevalence of central obesity, low HDL cholesterol and hypertension was higher in female patients. There was no significant relationship between MetS and stroke subtype. Conclusions : This work gives us the basic data on the association between MetS and risk of stroke. There should be the prospective cohort studies to evaluate MetS and the risk of stroke.

Objective : Western sleeping pills work very fast and effectively against insomnia. But they also bring about many side effects. Therefore oriental medicine can be a good alternative remedy. There are many clinical reports about patients treated for insomnia after stroke using oriental medicine. However, there are no clinical report about patients treated for insomnia after stroke diagnosed by Gobub & Bokjin. We want to prove the effect of Gobub & Bokjin in diagnosis and treatment for the insomnia patients after stroke. Methods : We chosed a patient who had suffered from insomnia after stroke. We administered acupuncture treatment, as well as Herbal medicine(Bokryoungum and Sanjoinsan). We monitored total sleep time per a day for 23 days. Results & Conclusion : Bokryoungum and Sanjoinsan was effective in improving overall sleep time day.

Objective: Participation restrictions are serious problems that stroke survivors experience while reintegrating into family, work, community, and social situations after participating in rehabilitation programs. The purpose of this study was to explore the factors affecting participation in activities of daily living (ADL), as well as social and leisure activities of individuals with hemiparetic stroke. Design: Cross-sectional study. Methods: The study involved 96 participants who were diagnosed with a first stroke 6 months before the study (58 men, 38 women; $60.3{\pm}14.3years$). The Berg Balance Scale, Modified Barthel Index, Manual Function test, and Activity Card Sort were used to assess static and dynamic balance function, upper limb function, level of independence, and their level of participation within the community. A regression analysis was used to identify the influence of factors affecting participation in ADL, social and recreational activities. Results: The Activity Card Sort scores were significantly affected by the Manual Function test and Modified Barthel Index scores (p<0.05). Participation in leisure activities was affected by the level of independence. Participation in social activities was affected by the balance function and level of independence of the participants. Conclusions: The results of this study have shown that participation restrictions are affected by upper limb function, balance function, and the level of independence in individuals with hemiparetic stroke.

A 21-year-old female patient complaining of hemiparesis was diagnosed with right middle cerebral artery infarction. No risk factor was found, despite an extensive young-age stroke work-up, except her history of marijuana use. The patient had smoked marijuana for treating depression for more than five years. Magnetic resonance angiography showed multifocal intra- and extracranial stenoses, suggesting cannabinoid-induced vasculopathy. Since the use of illicit drugs has increased nationwide, physicians should consider it as a possible cause of a stroke due to an unknown etiology.

The effect of graded increments in positive end-expiratory pressure [PEEP] on hemodynamics required to ventilate 8 critically ill patients is reported. Acute respiratory insufficiency was a cause of death in only one patient of drug inoxication among the 8 patients studied. The cardiac output was not changed significantly after the increment of PEEP to the level of 20 cm H2O. The heart rate was increased significantly from 15 cm H2O PEEP [P<0.01] as compared to 0 cm H2O PEEP; and the stroke volume was decreased significantly from 15 cm H2O PEEP [P<0.05]. The blood pressure was not affected at any level of PEEP, but the pulmonary artery pressure was elevated significantly at 10 cm H2O PEEP [P<0.01]. The right ventricular transmural filling pressure was not affected at the level of 10 cm H2O PEEP, but from 15 cm H2O PEEP it was increased significantly. With the increment of PEEP, the left ventricular stroke work index was decreased slightly; and at 20 cm H2O PEEP, it was decreased significantly. The right ventricular stroke work index was increased only at 10 cm H2O PEEP. The systemic vascular resistance was decreased significantly from 15 cm H2O PEEP [P<0.01].

The purpose of this study was to find out the effect of muscular strength of quadriceps, hamstring of knee joint to isokintic, isotonic exercise treatment in stroke. Data was collected from 80 stroke from January 10. 1994 to april 10, 1994 in a Chungnam university hospital. The results were as follows; 1. Peak torque was higher isokinetic than isotonic excercise group both in quadriceps and hamstring of knee joint, 6 weeks, 8 weeks 10 weeks showed statistically significant in isokinetic exercise training group. 2. Total work was high isokinetic than isotonic exercise group both in quadricaps and hamstring of knee joint, 10 weeks 12 weeks showed statistically significant in isokinetic exercise training group. 3. Average peak torque and total work was higher isokinetic than isotonic excercise group both in quadriceps and hamstring of knee joint, showed statistically significant in isokinetic exercise training group (p<0.05).(p<0.01). Isokinetic and isotonic exercise treatment were needed for sutable walk training in stroke. But I think that better method was isokinetic exercise treatment in muscular strength and endurance.

Social readjustment is very important in rehabilitation of stroke survivors. The purpose of this study was to examine the level of social readjustment and related factors in stroke survivors. Especially, to find the most useful predictor for social readjustment is a major point of this research. The study included 254 outpatients who were given follow-up care after discharge from. Occupational rehabilitation and resumption of the perceived meaningful social activity prios to the stroke were used to measure social readjustment. The resumptions of first meaningful social activity was the best predictor for life satisfaction in stroke survivors(r=.245, p<.01). The substance of perceived meaningful social activities were job, meeting with friends, hobby and activities for the family. The sum of meaningful social activities (r=.175, p<.01) and occupational rehabilitation (r=.116, p<.05) were significantly related to life satisfaction. There were significant difference in IADL, depression and life satisfaction according to resumption of meaningful social activity. But, occupational rehabilitation was not related to depression. The level of social readjustment was different between occupational rehabilitation and resumption of meaningful social activity. It was 45.7% in the first meaningful social activity and 36.6% in occupational rehabilitation. The related factors with resumption of the first meaningful social activity were that of IADL, depression, illness intrusiveness and cognitive function. And the level of IADL, illness intrusiveness, cognitive function, and age were significantly related to occupational rehabilitation. In conclusion, we suggest that the resumption of the first meaningful activity in stroke survivors is the best predictor of social rehabilitation. Thus, nurses need to work for resumption of meaningful activity as well as occupational rehabilitation.

PURPOSE: The objective of this research is to investigate the effectiveness of mental practice on function and muscle activation of upper extremity (UE) in stroke patients. METHODS: The mental practice was conducted on 12 subjects for 10 minutes and the related existing work treatment for 20 minutes. The evaluation for the function of UE proceeded with Fugl-Meyer assessment of motor function (FMA) and muscle activity analysis instrument. Furthermore we analyzed patients' reaching activity by two stages, reaching phase and returning to original position phase. RESULTS: According to the research results, the subjects' upper limb function improved in all of the measured items and the total scores after the mental practice (p<.05). In muscle activity, CCR value was used to efficiently analyze the patients' reaching activity in the two stages of reaching stage and returning to the original position phase. While the elbow movement only had a bit of positive change (1.1%) in the reaching stage, both the shoulder (-12.3%) and elbow (-18.2%) movements had a positive change in the returning to original position phase. CONCLUSION: This research confirmed that the mental practice is effective for the enhancement of UE function for stroke patients. The result of this research can contribute to the progress of mental practice in clinical environment.
