BACKGROUND The purpose of this study was to find out predictors influencing on the clinical course of stroke during the first 4 weeks after the onset through statistical research, especially whether the blood glucose level after stroke and the stroke with Diabetes Mellitus correlate with functional impairments and neurological outcome or not. METHOD During 7 months period(from 1-1-1997 to 7-31-1997), 32 selected patients prognosed as acute cerebral thrombosis were studied by using Modified Barthel Index, PULSES profile in an attempt to correlate Diabetes Mellitus and hyperglycemia(more than $120mg/d{\ell}$, $150mg/d{\ell}$) with functional impairment and neurological outcome and to evaluate the influence of sex, the side of hemiparesis and age at admission, 1 week and 4 weeks after admision(admitted within 2 days after the onset). RESULT 1. The sex, side of hemiparesis and age had no significant effect upon functional impairment during first 4 weeks after the onset, but recurrent-stroke resulted in significantly higher degree of functional impairment than first-stroke during first 4 weeks after the onset. 2. The patients with Diabetes Mellitusin in acute cerebral thrombosis resulted in significantly higher degree of functional impairment than the patients without Diabetes Mellitus in acute cerebral thrombosis during first 4 weeks after the onset. 3. The patients with hyperglycemia in acute cerebral thrombosis resulted in significantly more severe neurological outcome than the patients without hyperglycemia in acute cerebral thrombosis within 2 days after the onset. CONCLUSION The study suggested that recurrent-stroke and Diabetes Mellitus were the poorer prognosis factors of functional impairment in acute cerebral thrombosis patients during first 4 weeks after the onset. and the poorer prognosis factor of neurological outcome in acute cerebral thrombosis patients was hyperglycemia within 2 days after the onset.

One of the maindisadvantages of Orthogonal Frequency Division Multiplexing (OFDM) is the Peak to Average Power Ratio (PAPR) problem. To reduce PAPR and improve the error performance of the OFDM signal over a fading channel, an OFDM system combining an Adaptive Symbol Selection Scheme (ASSS) and channel estimation can be used. Because of the side information of ASSS, however, the data rate decreases in the conventional ASSS OFDM system. In this letter, to overcome this impairment, we propose a technique to transmit side information by using pilot tones, and demonstrate that the proposed technique can give reasonable bit error rate (BER) performance.

This study aimed to investigate the effect of traditional Korean medical treatments on a stroke patient with gait disturbance, cognitive impairment, dysuria, and dysphagia. A 78-year-old female with chronic middle cerebral artery infarction had symptoms of gait disturbance, cognitive impairment, dysuria, and dysphagia. After being treated with Korean medicine therapies, including acupuncture and herbal medicine, the patient's symptoms were significantly improved. During all the treatments, Indices including manual muscle test, functional ambulation category, functional independence measuring, mini-mental state examination-K, global deterioration scale, pelvic symmetry, functional ambulation profile used to evaluate her symptoms indicated improvement in her symptoms, without any side effects. Traditional Korean medical treatments, such as acupuncture and herbal medicine, can be considered to be effective therapies for a stoke patient who has symptoms of gait disturbance, cognitive impairment, dysuria, and dysphagia.

Objectives : The mortality rate of subarachnoid hemorrhage(SAH) has been reduced recently due to refinement of microsurgical technique and improved perioperative management. Also, many survivors of SAH show excellent neurological recoveries. However, we found that a high proportion of the survivors do not fully regain their premorbid status in cognitive and memory function. Object of this study is to evaluate which factors might influence on cognitive and memory impairment in ruptured aneurysmal SAH patients. Methods : In this prospective study, a series of 66 patients with aneurysmal subarachnoid hemorrhage(SAH) from 1996 to 1998, most of whom had a "good" or "fair" neurological outcome, were assessed with various tests of cognition and memory function. All patients underwent clipping operation by pterional approach. Right side approach was performed in 16 case and left 21 cases. K-WAIS(Korean-Wechsler Adult Intelligence Scale) was used as method of cognition and memory function test. The time interval between SAH and assessment varied between 4 months and 8 months, averaging 6.2 months. Statistical analyses were carried out for each test score to see whether aneurysm site(A-com : non A-com), route of approach, age and sex, vasospasm, Hunt-Hess grade and Fisher CT group at admission, Glasgow Outcome Scale(GOS) at discharge affect cognitive and memory function. Results : Aneurysm site was not shown to be associated with performance on any test, and the initial grade (Hunt-Hess grade, Fisher CT group) of SAH and vasospasm had only minimal predictive values. The grade at discharge( GOS) was proved to be the best predictor of impairment of cognition and memory function within 1 year after operation. Conclusion : The authors conclude that the diffuse effects of SAH are more important than focal neuropathology in relation to cognitive impairment in this group of patients.

Background: Stroke patients usually have arm weakness, which affects trunks and arms. Objective: To investigate the effects of paretic side and non-paretic side arm training on trunk control and upper limb functions. Design: Randomized Controlled Trial (single blind). Methods: Twenty patients with stroke in hospital were enrolled in the study. Twenty subjects were randomly assigned to paretic side arm training group (PATG, n = 10) or non-paretic side arm training group (NATG, n = 10). Trunk impairment scale (TIS) was used for trunk control, and box and block test (BBT) was used for upper limb function. Training was conducted for 4 weeks. Results: PATG showed significant difference in TIS (static balance, dynamic balance, coordination, total score) and BBT. NATG showed significant differences in static balance, and dynamic balance and total score except for coordination and BBT. PATG also showed a more significant difference in BBT and coordination and total score than NATG. Conclusions: The arm training performed on the paretic side are more effective than those performed on the non-paretic side in improving both upper limb function and trunk control in stroke patients.

Objective: The purpose of this study was to compare walking conditions (straight line and curved path) on walking patterns in persons who had experienced hemiplegic stroke and to determine whether if they adapt their walking pattern and performances according to changes in environmental conditions. Design: Cross-sectional study. Methods: Forty-four hemiplegic stroke survivors participated in this study. This study measured walking performance in three different walking conditions, such as straight walking, the more-affected leg in the inner curve walking, and less-affected leg in the inner curve walking conditions, and a 2-dimentional gait analysis system was used as a primary measurement. This study also measured secondary clinical factors including the Timed Up-and-Go Test, the Trunk Impairment Scale, and the Dynamic Gait Index. Results: After analyzing, cadence and step length of the less-affected side, stride length in the more-affected side, and stride length in less-affected side were significantly different among the three different walking conditions in this study (p<0.05), but other temporospatial parameters were not significant. Cadence was the largest in the straight walking condition. Step length in the less-affected side, stride length in the more-affected side, and stride length in less-affected side were also the longest in the straight walking condition. Conclusions: The results of the study suggest that hemiplegic stroke survivors show walking adaptability according to changes in walking demands and conditions, and moreover, cadence and step and stride lengths were significantly different between straight and curved walking conditions.

This study is to investigate neuro-anatomical correlation between neuropsychological results and cerebral cortex thickness of cognitive ability in the brain MRI targeting the patients with mild cognitive impairment. It was that 78 people who were diagnosed as first Parkinson's disease followed by neuropsychological screening battery(Parkinson's disease with mild cognitive impairment: 39 people; Parkinson's disease with normal cognition: 39 people) and 32 people of normal group were selected. Correlation between mild cognitive impairment and normal cognitive impairment and correlation between neuropsychological screening battery and cerebral cortex thickness in the brain MRI were performed by independent sample t-test or Pearson correlation coefficient and then level of significance of collected data was verified in p<0.05. As a result, cerebral cortex thickness of the Parkinson's disease with mild cognitive impairment in both side precuneas and right inferiortemporal lobe had statistically significant decrease. In addition, function of visuospatial ability, verbal and visual memory was reduced in neuropsychological screening battery for cognitive assessment. Especially, there was correlation between neuropsychological screening battery of verbal and visual memory anatomical left precuneus.
