This study was performed to investigate the clinical pictures and rehabilitation service patterns of stroke patients in cities of kimchon(kumi), jinju. pohwang, jeonju and jeju from January 1,2001 to march. Authors developed structured questionnaire, and distributed it to each physical therapist. Total number of distributed questionnaire was 400, and 301 questionnaire were col looted and analysed finally.1. The occurrence rate of hemorrhagic stroke(60.5%) was higher than that of ischemic stroke(39.5%). The highest incidence of the stroke was noted in the group of 50 years and ratio of male to female 1.3 : 1. 2. The several warning sign is motor deficit(42.5%). headache. dizziness, vomitting(31.9%) and difficulty speaking or understanding(10.6%). 3. The most important contributing factor of stroke was hypertension both hemorrhagic(50.0%) and ischemic stroke(40.3%). 4. In the painful stroke patients(53.2%). the major problems were shoulder pain(51.3%) and shoulder-hand syndrom(31.3%). 5. In hemorrhagic stroke. the seasonal preference was autumn and summer. In ischemic stroke. the seasonal preference was autumn and winter. 6. In the surgery, hemorrhgic stroke(44.5%) was higher than that of ischemic stroke(20.2%). 7 The major impairment were motor deficit(95.3%), psychological deficits(24.4%), hearing and speech deficit(23.4%). vision deficit(14.7%) and perception deficit(12.7%). 8. The rehabilitation services for stroke patients were physical therapy(98.0%), occupational therapy(41.5%), oriental therapy(35.1%), speech therapy(17.5%) and psychological therapy(7.4%). 9. The start of rehabilitation service was different according to surgery. 36.5% of patients started physical therapy in 4 week and 32.0% of patients started in 8 week later in surgery and 53.1% of patients started physical therapy in 2 week in not surgery( P<0.05). 10.

Objective : This study was aimed to investigated the warning signs and its relationship with the other characteristics in acute stroke patients. Methods : Three-hundred sixty three acute stroke patients were recuited in the oriental medical hospitals of 3 universities located in metropolitan region from October in 2005 to October in 2006. We evaluated their stroke type with brain MRI, their waring signs, and general characteristics such as age, sex, past history, risk factor, etc. Result : Of the 363 patient, 138(38%) patients were experience of warning signs. The frequency of Stress were found more in experience of warning signs than none of them. Warning signs were more common in Large Artery Atherosclerosis than in the other etiology. Conclusion : Although a concrete conclusion can hardly be drawn from this study, it reminds physicians of the importance of warning signs which their patients appeal. For the further investigation, it seems to be necessary to construct fundamental databases for stroke by increasing the number of patients and by examination into the etiology and location.

Purpose: A CT angiography spot sign (CTA-spot) is a significant predictor of the early expansion of an intracerebral hemorrhage (ICH-Ex). Dynamic-susceptibility-contrast magnetic resonance imaging (DSC-MRI) can track the real-time leaking of contrast agents. It may be able to indicate active bleeding, like a CTA-spot. Materials and Methods: From September 2014 to February 2017, we did non-contrast CT, CTA, and DSC-MRI examinations of seven patients with acute ICH. We investigated the time from symptom onset to the first contrast-enhanced imaging. We evaluated the time course of the contrast leak within the ICH at the source image of the DSC-MRI and the volume change of ICH between non-contrast CT and DSC-MRI. We compared the number of slices showing CTA-spots and DSC-MRI leaks. Results: The CTA-spot and DSC-MRI leak-sign were present in four patients, and two patients among those showed ICH-Ex. The time from the symptom onset to CTA or DSC-MRI was shorter for those with a DSC-MRI leak or CTA-spot than for three patients without either (70-130 minutes vs. 135-270 minutes). The leak-sign began earlier, lasted longer, and spread to more slices in the patients with ICH-Ex than in those without ICH-Ex. The number of slices of the DSC-MRI leak and the number of the CTA-spot were well correlated. Conclusion: DSC-MRI can demonstrate the leakage of GBCA within hyperacute ICH, showing the good contrast between hematoma and contrast. The DSC-MRI leakage sign could be related to the hematoma expansion in patients with ICH.

Stroke is the leading cause of adult disability and the third leading cause of adult death in the world. Stroke has an impact on the physical, psychological and social dimensions of quality of life. An increasing number of authors have reported a deterioration of the quality of life in a large proportion of patients after a stroke. Just as satisfaction with each dimension varies to everyone, the importance of each dimension also varies and does not impact equally on the quality of life. So assessment on the quality of life has to adopt a multidimentional approach and to make use of the subjective and objective indicators.

Numerical simulations are conducted to investigate the mechanism for force generation of an insect with tandem wing configuration. Various stroke amplitudes, stroke plane angles and phase difference between the fore- and hind-wings are considered. The Reynolds number is 150 based on the chord length and maximum translation velocity of the wing. When an insect requires high lift such as takeoff, it flaps its wings in parallel at a lower stroke plane angle and a bigger stroke amplitude than those in the hovering. With wings in counter-stroke, the lift fluctuations decrease, and moreover mean lift force decreases. Interactions among the fore-wing, hind-wing and vortices are examined to explain the force variations

Objectives: Although it is difficult to define the quality of stroke care, acute ischemic stroke (AIS) patients with moderate-to-severe neurological deficits may benefit from thrombectomy-capable hospitals (TCHs) that have a stroke unit, stroke specialists, and a substantial endovascular thrombectomy (EVT) case volume. Methods: From national audit data collected between 2013 and 2016, potential EVT candidates arriving within 24 hours with a baseline National Institutes of Health Stroke Scale score ≥6 were identified. Hospitals were classified as TCHs (≥15 EVT case/y, stroke unit, and stroke specialists), primary stroke hospitals (PSHs) without EVT (PSHs-without-EVT, 0 case/y), and PSHs-with-EVT. Thirty-day and 1-year case-fatality rates (CFRs) were analyzed using random intercept multilevel logistic regression. Results: Out of 35 004 AIS patients, 7954 (22.7%) EVT candidates were included in this study. The average 30-day CFR was 16.3% in PSHs-without-EVT, 14.8% in PSHs-with-EVT, and 11.0% in TCHs. The average 1-year CFR was 37.5% in PSHs-without-EVT, 31.3% in PSHs-with-EVT, and 26.2% in TCHs. In TCHs, a significant reduction was not found in the 30-day CFR (odds ratio [OR], 0.92; 95% confidence interval [CI], 0.76 to 1.12), but was found in the 1-year CFR (OR, 0.84; 95% CI, 0.73 to 0.96). Conclusions: The 1-year CFR was significantly reduced when EVT candidates were treated at TCHs. TCHs are not defined based solely on the number of EVTs, but also based on the presence of a stroke unit and stroke specialists. This supports the need for TCH certification in Korea and suggests that annual EVT case volume could be used to qualify TCHs.

This study examined the relationships between protein expression and Poly ADP ribose polymerase in brain cell death in brains damaged by thrombotic stroke and treated with the Full Wave- Cockroft Walton (FWCW) method of Transcranial Magnetic Stimulation (TMS). The two-way switching element for TMS drove a half-bridge inverter of the current resonance of direct current voltage (+) and direct current voltage (-), and the experiment was conducted by stimulating the mice with thrombotic stroke through a range of pulses. Thrombotic stroke was caused of ligation of the common carotid artery of male SD mice, and blood reperfusion was conducted five minutes later. Protein expression was examined in immune reaction cells, which reacted to an antibody to Poly ADP ribose polymerase in the cerebrum cells, and western blotting. Observations of the PARP changes after thrombotic stroke showed that the number of Poly ADP ribose polymerase reactions were significantly lower (p < 0.05) in the group treated with TMS of the FWCW than the group with thrombotic stroke 24 hours after its onset. The application of FWCW-TMS helped prevent the necrosis of nerve cells and might prevent the brain damage that occurs as a result of thrombotic stroke, and improve the function recovery and disorder of brain cells.
